Perhaps the most controversial aspect of the plan to overhaul the nation’s nuclear arsenal is the replacement program for the intercontinental ballistic missile (ICBM) force, the land-based leg of the nuclear triad that also includes submarine-launched ballistic missiles (SLBMs) and heavy bombers. The current deployed fleet of 400 silo-based Minuteman III ICBMs are distributed across three bases touching five states and are expected to be removed from service by the U.S. Air Force in the mid-2030s.1 A follow-on ICBM system–known as the Ground-Based Strategic Deterrent (GBSD)–is scheduled to replace the Minuteman IIIs (and their supporting infrastructure) on a one-for-one basis between 2028 and 2035.2 Many have questioned the need for this program, including former Secretary of Defense William Perry, who has argued for eliminating all ICBMs.3

The latest independent Pentagon acquisition cost estimate to design and build the ICBM replacement ranges from $85 to over $140 billion (in then-year dollars),4 while the cost to operate and sustain the weapons system over its expected 50-year service life is projected at roughly $150 billion.5 This ICBM recapitalization cost is but one piece of a larger plan to sustain and upgrade the nuclear arsenal over the next thirty years, with the total price tag projected to exceed $1.2 trillion (in 2017 dollars).6 Separate modernization programs planned for U.S. conventional forces will require additional outlays. These upgrades will necessitate either a significant and prolonged increase in defense spending, which is unlikely to be forthcoming, or a reallocation of resources within the defense budget.7 Hard choices will likely be required among competing programs.

The Trump administration’s Nuclear Posture Review published in February endorses replacing and upgrading the current Minuteman III force with the GBSD program. It will be up to Congress to assess the program’s cost-effectiveness and evaluate alternatives. This paper will examine this issue in several stages: first, by considering whether ICBMs are needed to hedge against threats to the strategic submarines; second, by discussing their possible benefits and risks as a warhead “sponge”; third, by examining whether ICBMs possess necessary capabilities absent from other legs of the triad; and last, by considering the stability implications of developing a new ICBM with enhanced capabilities. Finally, the paper evaluates alternative options to the costly GBSD program of record.

HIGHLIGHTS

  • The deterrent value of the ICBM force is small and diminishing.
  • Without ICBMs, the current absence of any foreseeable threat to the U.S. strategic submarines assures that no adversary can preempt massive retaliation by the United States.
  • ICBMs should not be considered an acceptable hedge against possible future threats to the
  • strategic submarines.
  • ICBMs provide no unique nuclear strike capabilities not already provided by other legs of the strategic triad.
  • The enhanced capabilities planned for the GBSD are either unnecessary or may adversely affect strategic stability.
  • Consequently, the United States should consider eliminating its land-based missiles or abandoning or scaling back the planned GBSD program.

Are ICBMs needed to hedge against foreseeable SSBN vulnerabilities?

A central, if not the central, rationale for maintaining the ICBMs rests upon fears of vulnerability in the strategic nuclear submarine (SSBN) force.8 If the SSBNs are unable to withstand threats to their survivability and deliver nuclear weapons to the homeland of an adversary, it is argued, then the ICBMs provide a backup to carry out that mission. Absent any such threats, maintaining the ICBMs for the purpose of deterring nuclear attacks is more difficult to justify.

Concerns that technology may one day render SSBNs vulnerable have existed since nuclear weapons were first placed on submarines during the Cold War. And while U.S. SSBN vulnerability was last studied in the public domain several years ago, no prior scholarship has revealed any doubt about the survivability of the sea-based leg of the triad. Among these previous studies includes one 1983 paper by Richard Garwin that suggested the extraordinary demands of holding an SSBN in trail by passive acoustics9 would not threaten the force, and in any case, that countermeasures would very likely deter the attempt.10 Garwin further concluded that short-range sensors would be required by the “hundreds of thousands” to make the SSBN force vulnerable to attack.11 A different study claimed that countermeasures are even easier to deploy against attempts to acquire an active acoustic trail and that such threats are easily neutralized.12

(Photo: Ian Dudley/U.S. Air Force)Another study from 1994 by Eugene Miasnikov relied on the fundamental physics of sound propagation in the ocean to calculate the maximum range at which Russian strategic submarines could be detected. Miasnikov found that the ranges were so short that not only were covert trailing threats using passive acoustics implausible, but that the increasing silence of submarines in both the United States and Russia risked causing accidental collisions.13 This suggests that unintended mishaps have been the greater threat to SSBN survivability than from any capability intended to hold them at risk.

In addition, no nonacoustic means of detection has been found to present a survivability threat. All indications suggest that every possible nonacoustic signal–with the possible exception of subsurface water motions detected on the ocean surface by synthetic-aperture radar–can be attenuated if SSBNs patrol at greater ocean depths or if certain operational procedures or other countermeasures are implemented.14

Of course the possible detection of a U.S. SSBN is an insufficient basis upon which to judge their vulnerability. Once detected, an SSBN would need to be localized to within the range and accuracy of the weapon used to destroy it, and then successfully trailed while other U.S. SSBNs at sea were detected, localized, and trailed with acceptable confidence. Only after concluding that this circumstance may arise within a considered period could the survivability of the sea-based leg be brought into question.

Recent advancements in technology, however, have raised questions about possible future vulnerabilities. In particular, improved acoustic sensors, lasers, signal processing advancements, and unmanned undersea vehicles (UUV) have been mentioned as possible threats to the ability of submarines to remain concealed.15 Despite this concern and the need for an up-to-date review of fundamental survivability prospects in the public domain, no analysis has yet challenged the conclusions of the studies cited above.

Any review of SSBN survivability should consider whether these technological advancements neutralize the survivability gains made by the modernization and deployment of increasingly quiet submarines over the past few decades. What’s more, the U.S. Navy is planning to replace the existing fleet of 14 Ohio-class submarines with 12 new Columbia-class submarines that will use new technologies related to stealth to ensure the new boats will remain serviceable through the 2080s.

(Photo: John Kowalski/U.S. Navy)Factors that should be evaluated include: What is the maximum range at which any technology can detect an SSBN? If further localization to bring the target SSBN within range of a weapon to destroy it is necessary, what would be required? How do UUVs and advanced computer processing capabilities affect the challenge of trailing SSBNs? If any evolving technology adversely affects SSBN survivability, are there any countermeasures that could prevent an adversary from identifying real SSBNs? Even if the U.S. government has not developed countermeasures for certain detection technologies, how would an adversary reach this conclusion if possible countermeasures could be imagined? Could the U.S. government develop the necessary countermeasures? What confidence would an adversary then need before convincing itself that detecting and destroying U.S. SSBNs is possible before a second strike response from the United States?

It is important to note that one Ohio-class SSBN is armed with roughly 100 warheads–each with a yield of 100 kilotons (kt)–and carries 500 times more explosive energy than did the atomic bomb dropped over Nagasaki at the end of World War II.16 This is almost certainly an underestimate given that some deployed warheads on SSBNs have yields of 455 kt.17 If a single survivable SSBN only had a single 100 kt nuclear warhead uploaded onto each of its 20 Trident II D5 SLBMs, the total explosive energy would be equivalent to 100 Nagasaki bombs. Without ICBMs, each of these SSBNs at sea, both SSBN bases at Kings Bay, Georgia, and Bangor, Washington, and all nuclear-capable heavy bombers would need to be destroyed by an adversary before either a bomber or SSBN could retaliate with nuclear weapons in a second strike.18

Moreover, the long-acknowledged vulnerability of the ICBMs19 make them an unsuitable hedge against any threat to the SSBNs. To provide a useful backup, the ICBMs must be launched under attack, and possibly even on warning of an attack.20 This is unattractive because to prevent their destruction by Russia (and perhaps China in the future) a decision to launch would need to be made in only a few minutes, if not less, after detection and before knowing whether the attack is a false alarm. The deterrent value of this launch posture then rests upon the United States demonstrating commitment to it and hoping that an adversary believes it. While an argument could be made that the prospect of launching ICBMs under attack enhances deterrence, convincing U.S. adversaries that Washington would risk starting an accidental nuclear war to defend the life of the United States–when no adversary is capable of preempting massive U.S. retaliation–should be considered unacceptable.

If concerns exist about SSBN vulnerability, consideration should be given to developing a mobile or another more survivable ICBM basing mode with plans to deploy it quickly if any threat to the SSBNs arises. Mobile missiles would probably force an attacker to barrage a deployment area with nuclear weapons and deceptive basing modes would proliferate an attacker’s aim points, but both would provide a more survivable SSBN backup. Due to drastically higher costs and land constraints, however, alternatives to the fixed silo-based ICBMs appear politically infeasible; indeed, the current GBSD program plans to retain silo-basing. In any case, given expected SSBN invulnerability, threats to a more survivable ICBM are more likely to materialize first.

No rationale based upon fears of SSBN vulnerability therefore exists for spending a large sum of money to replace the ICBM force, and vulnerable silo-based ICBMs with a launch under attack option should not be considered an acceptable hedge against possible future SSBN threats.

Limitations of the ICBM “sponge” rationale

During his January 2017 confirmation hearing before the U.S. Senate Armed Services Committee to become Secretary of Defense, General James Mattis stated that the deterrent value of the ICBMs is derived from the notion “that they are so buried out in the central U.S. that any enemy that wants to take us on is going to have to commit two, three, four weapons to make certain they take each one out. In other words, the ICBM force provides a cost-imposing strategy on an adversary.”21

This is a common justification for retaining a large and distributed ICBM force given the unlikely prospect of an adversary successfully destroying 400 targets. If an adversary also accepts Mattis’s premise, the large number of ICBMs could provide meaningful deterrence. Even if an adversary imagined it was possible to destroy all 400, their need to use a significant fraction of their arsenal to do so would then limit the number of warheads remaining to target U.S. cities. This is known as the warhead “sink” or “sponge” rationale for retaining the ICBM force.

Yet this reasoning has significant limitations, beginning with how improving missile accuracy will make the ICBM force less of a warhead “sponge” in the future. Today the probability of destroying a Minuteman III missile silo with a single Russian warhead could exceed 98 percent given advancements in inertial guidance that could be aided with a Global Positioning System (GPS) and maneuverable reentry vehicles (MaRVs) to improve accuracy.22 While this may be an overstatement now, it should not be expected to remain one.

From the New Strategic Arms Reduction Treaty (New START) level of 1,550 warheads, a successful 1:1 attack on each of the 400 U.S. ICBMs would leave Russia with 1150 strategic nuclear warheads free to target U.S. command and control and civilian population centers. Even if two Russian warheads were needed to destroy each Minuteman III silo with the desired probability, 750 warheads would still remain–more than enough to destroy American society.

Furthermore, a 1986 study calculated that the nuclear blast and radioactive fallout from an attack with two 500 kt warheads exploding over each of the then 1,000 operational U.S. ICBM silos, 100 launch control centers (LCCs), and 16 missile test silos at Vandenberg Air Force Base would cause between 2.4–15.0 million deaths and an additional 4.0–31.8 million casualties.23 While this calculation should be updated, a nuclear attack on 400 ICBMs today could still cause millions of fatalities given the larger populations living downwind of the bases.24

Maintaining the ICBMs for use as a warhead “sponge” requires that Russia direct its warheads at the American homeland in order to target missiles that can destroy their country in the event of a nuclear war. Conversely, Russia would not need to threaten millions of American lives­ in this manner if the ICBMs did not exist. The number of homeland targets used for launching nuclear weapons should therefore be kept as small as possible to limit the number of nuclear warheads an adversary would be required to detonate inside the United States. As nuclear strategist Thomas Schelling wrote in 1987:25

“If we unilaterally dismantled our land-based missiles, we would instantly deprive a large part of the Soviet land-based missile force for its raison d’être. It might look to them as if they had much less to preempt. They actually would not, because the U.S. missiles they might have preempted were redundant in the first place. Looking over a seascape inhabited by U.S. submarines and at bombers likely to be launched on warning, they would see, without the smoke and the ruins, what would have been left over after they preempted. So if we cannot dismantle their land-based missiles by negotiation, we may gain a lot by dismantling their targets instead.”

Schelling went on to add that, “It may be hard to know which it is that the land-based missile forces on both sides would lament most–the loss of their missiles or the loss of their favorite targets.”26

If one still accepts the “sponge” rationale, however, a new GBSD missile is unnecessary because an adversary would still be required to attack life-extended Minuteman III missiles to limit damage. In any case, there is no way to eliminate the capability to target American cities other than by reducing the number of nuclear weapons through arms control.

Yet this analysis of the ICBMs as a warhead “sponge” is incomplete, having thus far only suggested that more American lives would be saved without an adversary needing to target U.S. ICBMs in a nuclear war. But what about the effect of ICBMs on the likelihood of nuclear war itself? Does the ICBM force increase or decrease the chances of a nuclear exchange?

Despite whatever complications may exist for executing a successful first strike on 400 ICBMs, reliance on them to deter attacks is problematic given their vulnerability, and the consequent deterrence value they provide should be considered small. That being said, how would the motivation arise during peacetime to attempt such an attack if the SSBNs–and possibly other survivable means of retaliation by the American military–could not also be destroyed? It is doubtful that ICBM vulnerability in this case invites preemptive attack.

In a severe crisis that involves missile exchanges, major battles, or the loss of some strategic nuclear targets by conventional means, however, an adversary could conclude that escalation to the nuclear level is imminent. And if they decide that it is preferable to be attacked with fewer weapons rather than more,27 attention could turn to the ICBMs and other vulnerable U.S. military targets. This concern is supported by both Russian and U.S. nuclear counterforce doctrines designed to limit damage if nuclear war appears inevitable, with the risk heightened from ever-improving counterforce capabilities against silo-based ICBMs due to missile accuracy improvements worldwide. In this case, nuclear warheads directed against 400 ICBM targets would kill millions of more Americans than if only vulnerable U.S. command and control targets, bomber bases, and SSBN bases were preemptively destroyed.

This appears to be the most likely circumstance in which the ICBM force could be targeted–an escalating conflict that convinces an adversary to do as well as possible. The benefits imagined from destroying more versus fewer targets could then increase the likelihood of an attack. In such a crisis, it may therefore be better to demonstrate more clearly what forces cannot be preempted rather than what can. As Thomas Schelling wrote about the prospect of the United States dismantling its ICBMs: “It looks like a posture quite stable against all the motivations that could lead to an outbreak of unwanted nuclear war.”28

Do ICBMs provide other benefits?

Beyond complicating the execution of a successful first strike, the ICBMs are assumed to offer other benefits. One of these is that of the three triad legs, the ICBMs can be launched most quickly. As a December 2016 report by eight U.S. Senators in the ICBM Coalition claimed, the “ICBMs give the President a timely response option.”29

Yet a 1993 report by the Government Accountability Office (GAO) stated that Communications, Command, and Control (C3) to SSBNs “is about as prompt and reliable as to ICBM silos, under a range of conditions.”30 The same report also found “no operationally meaningful difference in time to target” between the ICBMs and SLBMs indicating that the ICBMs were not needed for any time-sensitive targets.31

There also exists a presumption that ICBMs either are or should be used for targeting an adversary’s nuclear forces and command and control–known as “counterforce” targeting–to limit damage to the United States. While this is possible, their vulnerability would require a “launch under attack” option to destroy targets of any value. Avoiding this unattractive option leaves doubt about whether any ICBMs would survive an attack, and then the consequent demand that targeting requirements be satisfied without them would be as if the ICBMs did not exist at all.32

In addition, ICBM flight trajectories to plausible targets in China, North Korea, and Iran must pass over Russian territory.33 If Russia interprets a U.S. ICBM launch intended for another state as an attack on them, they may retaliate with a nuclear strike of their own. This possibility should rule out applying any credible deterrence rationale for the ICBM force to these other US adversaries because all could reasonably conclude that retaliation with ICBMs is unlikely if it risks triggering an unwanted nuclear war with Russia. In other words, without other weapons systems to deter nuclear attacks by other adversaries, ICBMs should not be expected to deter.

Without ICBMs, the United States could still deploy an arsenal of 1,150 New START accountable warheads against the following counterforce targets:34

Russia: WMD targets (456 warheads in 2-on-1 attacks against 228 missile silos); leadership command posts (110 warheads); war-supporting industry (136 warheads). At least 80 of these warheads would likely be assigned to destroy targets in the greater Moscow area alone

China: WMD targets (150 warheads in 2-on-1 attacks against 75 missile silos); leadership command posts (33 warheads); war-supporting industry (136 warheads).

North Korea, Iran, Syria: Each country would be covered with (43) warheads.

This plan lays out how U.S. warheads could be directed against the fixed targets of plausible adversaries. The total number could exceed 1,150 because each bomber is only counted as one under New START counting rules. Also neglected here are the very substantial counterforce capabilities of U.S. tactical nuclear weapons and conventional forces. This destructive power is more than sufficient to deter any rational adversary and provides the same counterforce coverage to limit damage to the United States regardless of whether the ICBMs are maintained.35

In sum, any imagined benefits regarding the promptness of ICBMs to deliver nuclear warheads to their assigned targets and counterforce targeting capability are practically nonexistent. The “launch under attack” requirement for using ICBMs in counterforce would also reduce the time the president has to evaluate response options, thereby increasing the risks posed by false warnings or miscommunication in a crisis.

A technological arms race may adversely affect strategic stability

Proponents of the ICBM leg also argue that replacing the Minuteman III with the GBSD should be valued for the capability enhancements to be included on the new missiles. In particular, some claim that new capabilities are necessary for penetrating the future ballistic missile defenses of U.S. adversaries and improving counterforce capabilities.

When asked at a congressional hearing why the new ICBM needed more capability and accuracy, General Robin Rand, commander of Air Force Global Strike Command, replied:36

“Potential adversaries are continuing their modernization efforts of their defensive systems to attempt to minimize what our ICBM force can effectively hold at risk. In order to maintain a credible deterrent, the ICBM force must have the performance to overcome these defensive measures.

Improved ICBM capability and accuracy has the benefit of providing ICBM strike planners the weaponeering options of either achieving a higher probability of effect on a given target; using fewer warheads per target while still achieving the desired level of effect and thus allowing more targets covered; or provide opportunities to potentially reduce yield size while still achieving the desired level of effect. These weaponeering options will be critical if changes to the current strategic weapon stockpile would otherwise adversely impact what targets could effectively be held at risk.”

This claim is not convincing. The land-based leg of the triad can utilize a whole repertoire of countermeasures to overpower growing ballistic missile defenses: adding additional warheads on each missile; deploying decoys or radar-reflecting wires (chaff) to complicate warhead detection; jamming adversary radars or leading an attack with a nuclear explosion to blind infrared detectors; or adding thrusters to warheads to enable maneuvers.37 And this is only a small sample of potential options. The claim that new capabilities on the GBSD are necessary to defeat future missile defense deployments therefore requires much greater scrutiny before it can be seriously considered.

An unarmed Minuteman III ICBM shoots out of its silo during an operational test launch February 25, 2012 at Vandenberg Air Force Base, Calif.  (U.S. Air Force photo)A more serious implication is what the stated need for this missile may suggest to the world about U.S. motivations. As discussed, ICBMs must be launched under attack to be used in counterforce, but a strong presumption against this risk requires that targeting requirements be satisfied without them. What General Rand’s comments suggest instead is that the United States may wish to improve the first-strike counterforce capabilities on its ICBMs.

Advancing this prospect by equipping U.S. ICBMs with improved accuracy is unnecessary, and together with new low-yield options for its warheads, could be destabilizing. If hypersonic delivery becomes possible with a follow-on ICBM that shortens the warning time of an incoming attack, strategic stability may be further adversely affected. These acquisitions risk driving a technological arms race around the world where a country’s growing awareness that an increasing fraction of its nuclear deterrent may be successfully destroyed–possibly without warning—coupled with that same country’s growing confidence in its own counterforce capabilities against an adversary’s targets may increase the chances that nuclear weapons will be used. These evolving capabilities would only add to crisis stability concerns previously discussed.

Therefore, a new ICBM is unnecessary to defeat ballistic missile defenses and does not require enhanced counterforce capabilities given existing capabilities on other legs of its triad. Regardless of whether other states pursue new technological enhancements for their weapons, similar acquisitions by the United States­ will only drive these destabilizing efforts further.

Options for ICBM force deployment

Given the excessive redundancy, risks, and costs associated with the existing ICBM force, “launch under attack” posture, and replacement plans, the United States should consider several alternative deployment options. The alternatives presented here range from comparatively small ICBM reductions and cost savings to more substantial changes. Each of the following alternatives would still allow for a deployed strategic nuclear force with more than sufficient retaliatory capacity to deter nuclear attacks on the United States or its allies.

  1. Eliminate one squadron (50 missiles and their silos) at each of the three Air Force ICBM bases, reducing the number of deployed ICBMs to 300.38 If the number of SSBNs were also reduced to 10–but 1,550 warheads remained deployed–the Congressional Budget Office (CBO) estimates that $40 billion would be saved over the next three decades.39 This force structure would still allow the United States to deploy the 1,550 warheads allowed under New START. With only 150 ICBMs, 8 SSBNs, and 1,000 deployed warheads, $85 billion would be saved over the next three decades.40 (See chart above.)
  2. Reduce the total number of ICBMs and rotate the remaining missiles among the 400 remaining silos. This would preserve the “sink” rationale by requiring an adversary to attack every remaining silo–unless it could confirm which are empty–to ensure destruction of every ICBM. More money could be saved if some of the silos were also eliminated.
  3. Extend the life of the Minuteman III force. A 2014 study from the RAND Corporation found no evidence that long-term sustainment of the Minuteman III missiles, with incremental modernization, could not continue in perpetuity.41 And a recent CSIS report suggested that the life of Minuteman IIIs could be extended beyond 2030 for a period of time while deferring a decision on GBSD.42 If GBSD was deferred for 20 years, CBO estimates that $37 billion could be saved over this period and $17.5 billion over the next thirty years by simply life extending the Minuteman III.43 This would leave open the option for gradually reducing the size of the deployed ICBM force over time, either through unilateral reductions or in conjunction with a nuclear arms reduction agreement.
  4. Eliminate the ICBM force. The Congressional Budget Office (CBO) estimates that $149 billion could be saved between 2017–2046 if the ICBM force was eliminated immediately, and that $120 billion could be saved over this period if the ICBMs were eliminated at the end of the Minutemen IIIs service life.44 In the unlikely event that future SSBN vulnerabilities arise and it is determined by national decision-makers that a backup to the SSBN force is required, a more survivable ICBM basing option could be developed and deployed. However, it is important to note that this would likely involve a mobile ICBM, which would likely cost more to acquire than the GBSD.

Conclusions

Without a technically valid explanation for how an adversary could imagine it is possible to destroy the U.S. SSBN force, the land-based ICBMs are redundant for deterring nuclear attacks on the United States. Their location and vulnerability also hold at risk millions of American lives that no adversary would be required to threaten if the ICBMs did not exist. And because they require a “launch under attack” alert posture to be survivable, should be considered an unacceptable backup to SSBN vulnerability. ICBMs are also unnecessary for time-sensitive targets and counterforce targeting requirements must be satisfied without them in the event of a nuclear war.

Perhaps most importantly, ICBM vulnerability may attract a preemptive nuclear attack in an escalating conflict that U.S. opponents believe will inevitably escalate to the nuclear level or that threatens their lives, regimes, or other vital interests. These motivations are consistent with both U.S. and Russian nuclear counterforce doctrines which posit that it is better to be attacked with fewer weapons rather than more. Growing confidence in counterforce capabilities against fixed silo-based ICBMs only heighten this risk.

Lastly, a new ICBM with enhanced capabilities officially supported for the purpose of penetrating the modernizing missile defense systems of U.S. opponents and improving counterforce kill probabilities is unnecessary and potentially destabilizing. The range of countermeasures that can overwhelm missile defense systems are extensive and already accessible for inclusion on current weapons, and steps that indicate the United States may be motivated to develop disarming first-strike capabilities could accelerate a technological arms race that increases the chances of nuclear use.

The public debate over the new Nuclear Posture Review and start of the GBSD program provide an opportunity to reevaluate the least valuable leg of the U.S. nuclear triad. Given the confluence of growing budget pressures, unnecessary risks, and diminishing benefits of maintaining the ICBMs outlined here, U.S. interests would best be served by deciding to significantly reduce or eliminate them.

The bombers are organized into three bases: Minot Air Force Base in North Dakota, Barksdale Air Force Base in Louisiana, and Whiteman Air Force Base in Missouri. Assuming only eight SSBNs are at sea, the U.S. nuclear deterrent is then distributed over only 13 targets. See Kristensen and Norris, “United States Nuclear Forces, 2017.”

20 “Launch on warning” is a launch in response to a sensor indication of an attack on the continental United States, while “launch under attack” is a launch after a high-confidence determination of a massive attack. Because “launch under attack” requires more time to reach that higher level of confidence, a decision about whether to launch with this option must be made in a shorter time for ICBMs to survive the incoming attack. The definitions for these launch postures are approximately those provided by the Air Force, as mentioned in Richard L. Garwin, “Launch Under Attack to Redress Minuteman Vulnerability,” International Security, Vol. 4, No. 3 (Winter, 1979-1980), pp. 117–139.

22 If the circular error probable (CEP) of an 800 kt warhead from a Russian ICBM is 200 m, the single-shot kill probability (SSKP) against a U.S. Minuteman III silo is 0.88. If the CEP = 150 m (still a conservative estimate and less accurate than the U.S. Minuteman III), the SSKP is 0.98.

24 This is also likely true because a Russian nuclear attack today on U.S. ICBMs would require the use of warheads with a yield of 800 kt–the most common yield among Russian ICBMs—not the 500 kt modeled in Daugherty, Levi, and von Hippel, “The Consequences of “Limited” Nuclear Attacks on the United States.”

32 It deserves mention that the ICBMs receive some support for their potential use as first-strike counterforce weapons. Because one never knows how a nuclear exchange may begin, however, ICBMs cannot be used in counterforce targeting unless the United States is willing to commit to a “launch under attack” posture or the decision arises in a conflict to use them first before any warning of an incoming attack. The psychological effect that the presence of ICBMs may have on an adversary in contributing to nuclear deterrence due to their potential use as first-strike weapons is not necessary given the absence of any technically valid rationale for how an adversary could preempt massive retaliation by the SSBNs. Their presence is more likely to contribute towards convincing an adversary that the United States is about to launch a disarming first-strike–thereby increasing the chances of nuclear use–and as mentioned, their vulnerability only adds to the chance that they will be attacked first in an escalating conflict.

34 These numbers were taken from the report “Global Zero U.S. Nuclear Policy Commission Report: Modernizing U.S. Nuclear Strategy, Force Structure and Posture,” Global Zero, 2012, and numbers for Russian and Chinese nuclear missile silos were obtained from Hans M.

Norris, “Chinese nuclear forces, 2016,” Bulletin of Atomic Scientists, 72:4, 205–211. Three warheads were added to each total in the Global Zero report for warheads covering North Korea, Iran, and Syria to make the total number of warheads add up to 1,150. China may not currently have as many as 75 ICBM silos, but it could have more than this in the future.

35 It deserves mention that there is no meaningful difference in kill probabilities between ICBMs or SLBMs against the strategic targets of U.S. adversaries and that SLBMs are able to reach any target within range of the ICBMs.

In March 2017, Gen. Paul Selva, the Vice Chairman of the Joint Chiefs of Staff, told the House Armed Services Committee (HASC) that Russia had deployed a ground-launched cruise missile (GLCM) violating the “spirit and intent” of the 1987 Intermediate Nuclear Forces (INF) Treaty.1 Selva warned the committee that Russia is “modernizing its strategic nuclear triad and developing new nonstrategic nuclear weapons.” His testimony illustrates the new normal of U.S.-Russian relations, wherein historic nuclear cooperation is profoundly at risk.

Russia’s alleged INF Treaty violation has soured already strained relations between the world’s largest nuclear powers. Yet, the United States and Russia continue to share a common interest in ensuring nuclear stability worldwide. Together, the countries possess over 90 percent of the planet’s roughly 15,000 nuclear weapons. This power carries a responsibility to rejuvenate cooperative initiatives that reduce nuclear risks dating back to the depths of the Cold War.

To effectively evaluate the opportunities and challenges involved in that objective, U.S. policymakers must understand Russia’s current nuclear force policy and strategy. This policy paper examines Moscow’s nuclear doctrine, capabilities and modernization efforts, the status of U.S.-Russian arms control treaties, and the primary obstacles to cooperation. It concludes by offering a set of recommendations for both mitigating threats to strategic stability and resuming a productive U.S.-Russian arms control dialogue.

Background

The longstanding tradition of U.S.-Russian dialogue and cooperation to reduce the dangers posed by nuclear weapons—dangers that their rivalry and possession of nuclear weapons created—has been critical to global security and the health of bilateral relations in general. Indeed, during the Cold War, collaboration on nuclear matters was often the only tether holding the relationship together. The global nonproliferation order is weakening. It cannot afford continued noncooperation between the world’s two largest nuclear powers.

Current pressures on the U.S.-Russian relationship

Perhaps the greatest source of tension between Moscow and Washington is a fundamental difference of perspective on the post-Cold War European and international order. The Kremlin views its loss of superpower status following the Soviet Union’s collapse, and subsequent exclusion from international decision-making, as a root cause of many global problems. Under the leadership of President Vladimir Putin, the country is focused on regaining regional and global influence. Russian possession of nuclear weapons is a crucial component of these ambitions.

Moscow feels entitled to a sphere of influence in the post-Soviet space at the same time that Washington maintains an orbit in Europe through NATO and its European alliances. As part of a quest to strengthen its influence in Eastern Europe and Central Asia, Russia is expanding and deepening its information warfare and foreign economic activities to further weaken Western liberal democracy in these regions. There is clear evidence of Russian interference in the 2016 U.S. presidential election, as well as in recent elections in France, the Netherlands, and Germany, with the intention of swaying the vote in favor of nationalist, populist candidates sympathetic to Russia.

Furthermore, Moscow is supporting pro-Russia authoritarian and oligarchic-style regimes and political movements throughout Eastern and Central Europe and Central Asia. Perceived attempts by Washington to interfere in that zone are sure to have exacerbated tensions with Moscow. An example is the eastward expansion of NATO, which Russia fears perhaps more than any other geopolitical threat.

Russia’s most recent military doctrine, published in 2014, explicitly identifies NATO expansion as a major threat to Russian national security. Russia has viewed the eastward expansion of NATO as a menace since before the Soviet Union fell—and especially since the 1999 NATO bombing of Kosovo. Moscow is highly critical of U.S. intervention in past conflicts in the Balkans and Middle East, and remains suspicious that NATO intends to destabilize incumbent regimes in the post-Soviet space. The Kremlin directly blames Washington for inciting uprisings in Georgia, Ukraine, and the Middle East.

In Ukraine, Moscow blames the Obama administration for encouraging the Maidan revolution and views U.S. policy toward Crimea as hypocritical. In Syria, Russia and the United States have disagreed on a range of issues, including the use of airspace, the future of the Bashar al-Assad regime, Syria’s use of chemical weapons, Iran’s role, how to fight the Islamic State, and which parties to the conflict constitute terrorist organizations.2

Finally, Moscow has amplified its muscular military signaling in recent years. In Ukraine and Syria in particular Russia has exercised nuclear sabre rattling and dangerous brinksmanship. Both countries have engaged in increased military exercises and force buildups on the NATO-Russia border.3

Arms control is not dead, but it’s wounded

Arms control is an area where Russia and the United States must cooperate, despite numerous tensions in their relationship. Yet, disagreements over treaties, missile defense, and approaches to nonproliferation have created additional challenges.

The INF Treaty is at the center of a significant and ongoing arms control treaty dispute between Moscow and Washington. In 2014 the United States accused Russia of testing a GLCM that violates that agreement. Then, in 2017, Washington alleged that Moscow had deployed the system. The Kremlin denies the allegations, and instead accuses the United States of violating the agreement. Mounting distrust on the treaty threatens to affect other hallmark agreements, such as the 2010 New Strategic Arms Reduction Agreement Treaty (New START).

New START requires that the United States and Russia each reduce their strategic nuclear forces to no more than 1,550 deployed warheads, 700 deployed delivery systems, and 800 deployed and non-deployed delivery systems by February 2018. The treaty is slated to expire in February 2021 but can be extended for another five years by mutual agreement by the two presidents. Since New START went into force in 2011, bilateral talks on further reductions have been put on hold amid a litany of U.S. and Russian disagreements in both the nuclear and non-nuclear realms.

Moscow is troubled by the expansion of U.S and NATO missile defenses, particularly the Aegis Ashore system in Romania and another planned site in Poland. While NATO argues that the intention of the system is “to protect European NATO allies, and U.S. deployed forces in the region, against current and emerging ballistic threats from the Middle East,” Moscow views the system as directed against Russia.4 Moscow’s perception is underscored by the fact that U.S. missile defense deployment planning did not change following the achievement of the 2015 Iran nuclear agreement, which curtailed the Iranian nuclear threat.

On the U.S. side, there is concern that Russia is lowering its threshold for nuclear use, thereby increasing the potential that regional conventional conflicts could escalate into catastrophic nuclear collisions. While it is certainly possible to interpret Russian nuclear doctrine in this way, American and Russian analysts debate whether Moscow has indeed incorporated limited strikes as part of its official military doctrine.

Despite these irritants, past cooperation between the two powers on New START and the Joint Comprehensive Plan of Action (JCPOA) to limit and roll back Iran’s emerging nuclear program indicates that future cooperation is possible.5 However, statements by the Trump administration suggesting that the United States might pull out of the JCPOA, as well as withholding a certification to Congress tied to the deal, have seriously harmed this potential and led Moscow to question Washington’s commitment to arms control and nonproliferation.

Furthermore, the bilateral risk reduction enterprise is under siege. Since the end of the Cold War, Washington and Moscow have worked in partnership to combat the threat posed by non-state actor access to nuclear weapons, but recently that collaboration has stalled.

Trump-era developments

Immediately following Donald Trump’s 2016 presidential victory, some believed that U.S.-Russian relations would rebound due to Trump’s admiration of Putin, his stated desire to improve ties, and Putin’s clear preference for Trump over Clinton. Yet, evidence of Russian election interference and support for Assad in Syria soon led Trump administration officials to expand their criticisms of Moscow. Congress has taken additional steps to put economic pressure on Moscow and constrain the president’s ability to engage.

Trump has yet to articulate a clear policy toward Russia, including on arms control. In January 2017, the administration announced plans to conduct a comprehensive review of U.S. nuclear weapons policy, posture, and planning. The release of this document, called the Nuclear Posture Review (NPR), is expected in February 2018. While Trump has expressed a desire to improve relations with Moscow, and on occasion professed that global nuclear weapons inventories should be significantly reduced, he has also publicly pledged to strengthen and expand U.S. nuclear capabilities. In a January 2017 phone call with Putin, Trump reportedly denounced New START and rebuffed Putin’s suggestion to extend the treaty.

In May 2017, White House and Kremlin officials stated that they would pursue resumed talks on strategic stability. The two sides held a first round of talks on September 12 in Helsinki, Finland, led by Thomas Shannon, undersecretary of state for political affairs, and Russian Deputy Foreign Minister Sergey Ryabkov, but the specific agenda has not been disclosed, nor has a date for the next round of talks been scheduled.

Congressional action could undermine U.S. relations with Russia

Republican hawks in Congress have introduced provisions that could jeopardize key arms control treaties, including the INF Treaty and New START. In an attempt to counter Russia’s INF Treaty violation, the fiscal year 2018 National Defense Authorization Act (NDAA) would provide funding for research and development on a new U.S. road-mobile GLCM with a range prohibited by the treaty.6

Nuclear policy of the Russian Federation

Russia published its most recent military doctrine in 2014. Although it discusses nuclear weapons and use, it is not meant to be the last word on Russian nuclear policy.

What the latest military doctrine says

The most recent version of Russian military doctrine identifies the past, present, and future expansion of NATO, and NATO activities “in violation of international law,” as a primary threat to Russian national security. Other main threats include the “creation and deployment of strategic missile defense systems,” which the doctrine argues “violate the balance of forces in the nuclear-missile sphere,” and the “deployment of strategic non-nuclear systems” and precision weapons. The document also references the weaponization of space and cyber and electronic warfare.7

Although Russia’s military doctrine demonstrates a view of the United States and NATO as aggressors in an evolving security environment, it also highlights the value of the arms control architecture and exhorts the military to “conclude and implement agreements in the area of nuclear-missile arms limitation and reduction.”8

The doctrine states that the purpose of Russia’s nuclear forces is to serve as a broad deterrent, and adds that Russia reserves the right to use:

“nuclear weapons in response to use against it and (or) its allies of nuclear and other weapons of mass destruction, as well as in the case of aggression against the Russian Federation with the use of conventional weapons, when the very existence of the state is
under threat.”9

Earlier versions of the doctrine described a lower standard for nuclear use, which prompted debates on concepts of de-escalation and pre-emption.10 There is now a near consensus view in Washington that Russian doctrine includes a so-called “escalate to de-escalate” strategy, whereby Moscow would use nuclear weapons on a limited basis to bring a conflict with a conventionally superior opponent to a halt.

Yet, the 2014 version does not mention de-escalation or legitimize pre-emptive strikes, and it is vague or silent about many aspects of nuclear use, including the scale of a nuclear response to an existential threat. It also does not include a no-first-use declaration, a policy Moscow abandoned in 2000.11

What the Russian government is saying and doing

The words and actions of the Kremlin and military officials provide additional context and insight into Russia’s military doctrine. In recent years, officials have emphasized the role of nuclear weapons in Russian defense strategy. Many recent prominent Russian military drills have included simulated nuclear strikes, including the September 2017 Zapad exercises, which featured two tests of the RS-24 Yars intercontinental ballistic missile (ICBM).

Kremlin leaders frequently draw attention to the strength of the arsenal in their public statements and, on occasion, have referenced it when issuing warnings to the West, such as the time Putin praised Russian nuclear weapons and said, “it’s best not to mess with us.”12 In 2009, Russia’s Deputy Prime Minister Dmitry Rogozin said, “we will certainly resort to using nuclear weapons in certain situations to defend our territory and state interests.”13 The 2003 Report of the Defence Ministry of the Russian Federation, known as the “Ivanov Doctrine” after then Defense Minister Sergei Ivanov, defined de-escalation as “forcing the enemy to halt military action by a threat to deliver or by actual delivery of strikes of varying intensity with reliance on conventional and (or) nuclear weapons.” The state press also regularly features headlines announcing the augmentation or improvement of an aspect of the nuclear arsenal.

These statements generate confusion among analysts as to whether Russia is truly lowering its threshold for nuclear use. Such ambiguity may ultimately be Moscow’s objective.

What analysts think about Russian doctrine

Western analysts frequently speculate on the conditions that would prompt Moscow to employ nuclear weapons. As noted above, military doctrine states that an existential threat would prompt Russia to employ its nuclear arsenal. However, it is unclear precisely what conditions Russia considers as constituting a threat to the existence of the Russian state, or how to measure the circumstances that would motivate Russia to escalate a conflict with limited nuclear strikes.14 Paul Bernstein, senior fellow for the National Defense University Center for the Study of Weapons of Mass Destruction, wrote in a 2016 report that Russia likely views any conflict involving NATO as posing an existential threat.15

Alexander Velez-Green of the Center for a New American Security (CNAS) argues that rapid technological advances, which “give far greater advantage to the side that escalates first,” have made it likely that Moscow would consider a first strike in a conflict situation.16 After analyzing Russia’s robust nuclear modernization program, some analysts note that many of its systems being upgraded have the capabilities needed to carry out “limited nuclear strikes against both military and non-military targets of value to the Western Alliance.”17 Russia has also improved its advanced non-nuclear capabilities, including theater-range precision strike systems,18 which could indicate a “pre-nuclear level of deterrence.”19

Then-Deputy Secretary of Defense Robert Work testified before Congress in 2015 that Russian nuclear doctrine contains a de-escalation strategy.20 But because the concept of de-escalation is not mentioned in public military doctrine, analysts debate whether the concept is formally part of Russian nuclear policy.

Eldridge Colby, currently Deputy Assistant Secretary of Defense for Strategy and Force Development, argued in a 2016 report for the Foundation for Strategic Research that Russia’s possession of the capabilities necessary for limited nuclear strikes, coupled with reports of limited nuclear strikes in recent military exercises, signal that Russia is lowering its nuclear threshold.21 Although de-escalation is not explicitly mentioned in military doctrine, the fact that senior military officials often reference the concept suggests it is part of Russian defense planning.

Conversely, Olga Oliker, senior adviser and director of the Russia and Eurasia Program at the Center for International and Strategic Studies, argues that because the purpose of military doctrine is to apprise adversaries of intention, it would be only logical to mention a lowering of threshold in the document if that were truly Moscow’s intention.22 Beyond doctrine, Oliker writes that there is “unconvincing” evidence that Russia invokes such a strategy, instead arguing that Moscow is more concerned with reminding the world that Russia has the power and capabilities to escalate—without actually intending to do so. The point is to keep NATO and Washington on their toes.23 Oliker says that recent Russian military exercises are meant “to test the readiness and command and control of Russia’s strategic nuclear forces,” and not as a “preparation for tactical use.”24

Russian nuclear capabilities in 2017: current status and modernization plans

While it is difficult to make a precise assessment of the size and composition of Russia’s nuclear stockpile, experts have been able to provide estimates using New START aggregate data and data from monitoring sources. Analysis from Hans Kristensen, Robert Norris, and Pavel Podvig indicate that, as of 2017, Russia owns a total military stockpile of operational forces of 4,300 nuclear warheads. Of these, 1,960 are deployed on ballistic missiles and at heavy bomber bases, and 500 strategic warheads and 1,850 non-strategic warheads are in storage.25 The military’s Strategic Rocket Forces (SRF) manages ICBMs, the Navy manages sea-based systems, and the Aerospace force manages air and missile defense systems.

Modernization plans and the State Armaments Programme (SAP)

Russia has pursued a major upgrade of its nuclear forces over the past decade. The vast scale of the program seems designed to counter perceived threats from the United States and NATO and maintain strategic stability.26 The program includes an emphasis on modernizing strategic nuclear and aerospace defense forces. Russian Defense Minister Sergey Shoigu said in 2017 that the military would “continue a massive program of nuclear rearmament, deploying modern ICBMs on land and sea, [and] modernizing the strategic bomber force.”27

Russia commenced the State Armaments Programme 2020 (SAP-2020) in 2011 to expand and upgrade the technology of the Russian Federation’s Armed Forces from 2011-2020. The stated goal of the SAP-2020 is to modernize 70 percent of Russian arms and equipment by 2020. But sanctions on Russia, a punishment for Russian aggression in Ukraine, have slowed the Russian economy­—and with it, progress on the SAP. Despite economic concerns, Russia is modernizing all three legs of its nuclear triad.28 In a 2017 speech before the Ministry of Defense, Putin extended the deadline to 2021. In this address he stated that the Russian nuclear triad was 79 percent modernized, and that by 2021 ground-based nuclear forces would be 90 percent modernized.”29

Russia frequently justifies its nuclear force posture by signaling a need to defend against U.S. missile defense and conventional strike capabilities and keep up with the pace and scope of U.S. nuclear modernization. Russian Foreign Ministry Director of Nonproliferation and Arms Control Mikhail Ulyanov remarked in 2014 on ongoing U.S. modernization plans, declaring that Russia would “take corresponding countermeasures to ensure our security.”30 Regarding modernization, it should be noted that the Russian program began before that of the United States.

Putin said in 2016, “It is necessary to strengthen the combat potential of the strategic nuclear forces, primarily for missile systems capable of and guaranteed to overcome the existing and future missile defense system [of the U.S.]”31 Russia is building new ICBM systems equipped with multiple independently targetable reentry vehicles (MIRVs) and maneuverable warheads to counter the U.S. missile defense program.

Budget and cost estimates of Russia’s nuclear program

According to the U.S. Defense Intelligence Agency, Russia plans to spend approximately $28 billion by 2020 on upgrades to its strategic nuclear triad. The budget for SAP-2020 was initially planned with a much higher GDP growth rate than was actually achieved. When oil prices fell from the expected $50 per barrel to under $35 per barrel and GDP stalled, the military was forced to make budget cuts of up to 10 percent for each ministry. These cuts hampered modernization plans.32 At the same time, the defense budget continues to grow at a higher rate than the national GDP, likely due to the lobbying power of the Russian defense industry and the government’s strong commitment to modernization.33 However, U.S. defense spending still far outpaces that of Russia.

Russia announced plans to spend approximately 20.7 trillion rubles ($704 billion) on the SAP-2020 in 2011, although Western analysts believe 19 trillion rubles to be a more realistic figure.34,35 First Deputy Defense Minister Vladimir Popovkin, who oversees the SAP, said that the bulk of the funding would go to developing eight nuclear-powered strategic submarines equipped with the Bulava missile system, modernizing ICBMs, purchasing precision weapons, and building a heavy-liquid ICBM.36 By 2015, Russia had procured only 30 of 400 desired ICBMs and submarine-launched ballistic missiles (SLBMs), two of eight desired ballistic missile submarines (SSBNs), 11 of 56 S-400 missile defense systems, and two of 10 desired Iskander-M tactical ballistic missile brigades.37 Actual Russian spending in 2015 for the nuclear complex was roughly 44 million rubles. In 2016, it was 46 million.38

The Defense and Finance Ministries put forward competing proposals to fund the SAP-2025 for the years 2018-2025. The Defense Ministry proposed a 24 trillion ruble budget, while Finance proposed a budget of half that amount, at 12 trillion.39 The two ministries will need to reconcile these figures to produce a budget for approval.40

The intercontinental ballistic missile (ICBM) force

As of March 2017, Russia’s stockpile includes an estimated 316 intercontinental ballistic missiles (ICBMs) carrying 1,076 warheads. Russia is increasing its arsenal of ICBMs equipped with multiple warheads, possibly to account for a smaller ICBM force than that of the United States. By the early 2020s, most mobile Russian ICBMs are expected to carry ballistic missile payloads containing multiple warheads.

The Russian ICBM force includes the Topol (SS-25), Topol-M (SS-27 Mod 2), RS-24 Yars (SS-27 Mod 2), UR-100NUTTH (SS-19), and R-36M2 (SS-18). The latter two are the oldest ICBMs in the arsenal. The R-36M2 is likely to remain in service until 2022, when it will be replaced by a new silo-based liquid-fuel ICBM, called Sarmat. Development of the RS-24 Yars began after the Strategic Arms Reduction Treaty (START) expired in 2009. It is a MIRVed variation of the Topol-M. The RS-26 Rubezh (no SS- designation), Sarmat (no RS- or SS- designation), and Barguzin are in development.41

The Russians are retiring Soviet-era ICBM systems in order to gradually replace older systems with newer systems by the early-to-mid 2020s.42 The new ICBMs are MIRVed, road-mobile, and silo-based—mainly variants of the Topol-M/RS-24 Yars missile. The road-mobile RS-26 Rubezh is planned for deployment in late 2017 and the Sarmat will replace the RS-20V in 2019 or 2020, although it is behind schedule. The Sarmat is expected to be a liquid-fueled missile equipped with as many as 10 MIRVs, and may carry a hypersonic maneuvering warhead. It will be able to attack U.S. targets by multiple trajectories, thereby allowing it to overcome U.S. missile defense systems.43

The Defense Ministry had announced the development of five regiments of a rail-based ICBM, called “Barguzin.” Testing was planned for 2019, and deployment, by 2020.44 Each regiment was to contain six missiles. An ejection test was reported in November 2016.45 However, it was reported in December 2017 that the program had been canceled.46

The ballistic missile submarine (SSBN) and submarine-launched ballistic missile (SLBM) force

The Russian force contains 11 operational submarine-launched ballistic missiles (SLBMs) across three classes, including the Delta III and Delva IV classes, with a total of 176 missiles carrying 768 warheads. Each submarine can carry 16 SLBMs, for a total of almost 800 warheads. Russian SLBMs include the R-29R (RSM-50, SS-N-18 Stingray), R-29RM Sineva (RSM-54, SS-N-23), RSM-56 Bulava (SS-N-32), and, according to some sources, a version of the RSM-54 known as the R-29RMU2 Lanier.

Russia is developing eight Borey-class submarines to replace the ageing Delta III and IV submarines in the mid-2020s, three of which have already been built. The first three are Borey and the additional submarines are Borey-A. The fourth submarine will be introduced in 2019 and the last should join the fleet sometime in 2021. Each will be loaded with sixteen Bulava SLBMs carrying up to six warheads per missile.47

The bomber force

Russia maintains a bomber force of approximately 68 aircraft. Only 50 of the deployed nuclear-cable bombers carry assigned nuclear weapons. Of the estimated 68 planes, approximately 25 are TU-95 MS6 (Bear-H6) long-range bombers, 30 are TU-95 MS16 (Bear-H16) long-range bombers, and 13 are Tu-160 (Blackjack) supersonic long-range bombers. They are capable of carrying nuclear air-launched cruise missiles (ALCMs). As strategic heavy bombers they are subject to New START limitations. The Russian air force also operates a multipurpose medium-range supersonic bomber, the Tupolev Tu-22M, which is considered a tactical nuclear delivery platform for various types of cruise missiles. It is not limited by New START.48

Russia is reportedly replacing its current fleet of Tu-95’s, Tu-160’s, and Tu-22M’s with a new generation of strategic bombers by the early 2020s. These fleets are being upgraded to increase their conventional capabilities. In 2015, the Defense Ministry revealed plans to resume production of the Tu-160M2, an upgrade to the Tu-160, in the mid-2020s.49 It reportedly signed a $103 million contract to upgrade three of the 10 Tu-160 bombers slated for modernization.50 Over the next decade, Russia is also developing a new generation bomber called the PAK-DA.

Nonstrategic nuclear weapons

The Russian nonstrategic arsenal totals 2,000 weapons, including short-range surface-to-surface missiles, air-to-surface missiles and bombs, nuclear-armed torpedoes, depth charges, and surface-to-air missiles for air defense. At least 760 warheads are used by the Russian Navy.51 About 570 nonstrategic weapons are used by the air force.52

Moscow currently has a far larger arsenal of non-strategic weapons than the United States, although Moscow might say that it is more accurate to count U.S. non-strategic weapons in combination with those of France and the United Kingdom, thus reducing the asymmetry. None of these forces are limited by treaties. The Congressional Commission on the Strategic Posture of the United States, co-chaired by former Secretaries of Defense William Perry and James Schlesinger, found this imbalance to be “worrisome to some U.S. allies in Central Europe.”53

Russia is developing dual-use systems, weapons that can be deployed in nuclear and conventional variants. Both the Kalibr sea-based cruise missile, which has an intermediate range, and the Iskander ground-based ballistic missile represent this type of weapon. Moscow is nearing full deployment of the potentially nuclear-capable Iskander-M system, which comprises short-range ballistic and cruise missiles, to replace Tochka-U missiles.

According to Pavel Podvig, director of the Russian Nuclear Forces Project, the development of dual-use systems is worrisome from a stability perspective. He writes that the systems are capable of “blurring the line between nuclear and nonnuclear weapons.”54 The U.S. European Command 2017 Posture Statement declared that “Russia’s fielding of a conventional/nuclear dual-capable system that is prohibited under the INF Treaty creates a mismatch in escalatory options with the West.”55

Early-warning system upgrades

Russia is upgrading its strategic force support systems, such as early-warning launch detection satellites and ballistic missile early-warning radars. The SAP called for as many as 10 new early-warning satellites by 2020. These had fallen behind U.S. capabilities after the Soviet collapse.56 Three new early-warning radars were planned to become operational in 2017 as part of an upgrade program to Russian early-warning systems. Russia began deployment of a new early-warning space-based system, known as EKS, in 2015. Satellites of these systems can transmit information in real time to command centers at western and eastern locations.57 According to Shoigu, in 2017 Russia will achieve full coverage of its perimeter through a “continuous radar field of warning systems for missile attack on all strategic air and space directions and on all types of trajectory of ballistic missile flights.” This achievement is a result of the three new radars beginning combat duty, as well as upgrades to three older radars.58

Russia’s missile defense capabilities and modernization

Despite Moscow’s fierce criticisms of the U.S. missile defense program, Russia is expanding and upgrading its air and missile defense systems. Russia exports many of these systems abroad. The A-135 ballistic missile defense system has been operational around Moscow since 1995, after replacing the 1970s-era A-35 Galosh system. Russia operates several families of air defense systems, each consisting of multiple variants and upgrades. These include the S-300P, S-300V, and S-400 systems. The S-500 system is in development.59

The S-300P (SA-10 Grumble/ SA-20 Gargoyle) is comparable to the U.S. Patriot PAC-3 system. The PMU-2 version introduced the 58N6E2 missile, which is capable against short-range ballistic missiles (SRBMs) and medium-range ballistic missiles (MRBMs).60,61

The S-300V (SA-12/SA-23) is also comparable to the U.S. Patriot PAC-3 system. It can intercept both SRBMs and MRBMs. An unknown number of systems were deployed to Syria beginning in 2015.62

The S-400 “Triumph” (SA-21 Growler) was designed as an upgrade to the S-300 family. It entered service in 2007, but production has been slow. The system is purportedly capable of intercepting ballistic missiles with a range of around 3,000 km; however, the intercept would have to take place in the atmosphere, making its defense capabilities limited. An unknown number of these systems are deployed in Syria.63

The S-500 “Prometheus” is in development to be a comprehensive anti-ballistic missile system that works in conjunction with the S-400. This system extends the engagement envelope of Russian air defenses beyond an altitude of 30 km, making it an “air / space defense system.” It is currently undergoing testing. Russian defense officials claim that the system will be capable of defending against ICBM attacks.64

The A-135 Moscow missile defense system was designed to protect Moscow. It comprises the Radar Don-2NP, a stationary, all-around, multi-purpose surveillance centimeter-range radar station, the command-and-control center, shooting complexes including 12-16 silo launchers of anti-missiles, and high-speed 53T6 interceptors that operate at the terminal trajectory phase and are nuclear-armed.65 The A-135 is aimed at intercepting ICBMs and SLBMs. The system’s upgrade project, called the A-235 Nudol, will employ a new, conventional version of the 53T6 missile with a longer range and higher accuracy.66 As part of the missile defense system, Russia has located 68 nuclear-tipped ballistic-missile interceptors near Moscow. For comparison, the United States deploys 44 anti-ballistic missile interceptors in Alaska and California.67,68,69

Obstacles to arms control

The INF Treaty dispute

The INF Treaty required the United States and Soviet Union to eliminate and permanently forswear all nuclear and conventional ground-launched ballistic and cruise missiles with ranges of 500 to 5,500 kilometers. The treaty led the countries to destroy a total of 2,692 short-, medium-, and intermediate-range missiles by the 1991 deadline.70 Yet, beginning in 2014 Washington has accused Russia of violating the treaty by testing, and as of 2017, deploying, a GLCM with a prohibited range.

The Trump administration says the Russian system of concern is the SSC-8 ground-launched cruise missile, which, according to the U.S. government, uses the Russian designator 9M729. Because Washington has not been transparent to the public about the violation, very little is known about the noncompliant system. Some have speculated that it is a ground-based version of the Kalibr missile, while others believe that the illegal missile is a follow-on to the R-500/SSC-7 Iskander missile. The SSC-8 is likely capable of targeting major European and east Asian cities, respectively, from Russia’s far western and eastern bases.71

Analysts have suggested various possible rationales for Russia’s development and deployment of the noncompliant system. Analysts point to a desire to enhance theater strike capabilities, increase the survivability of its forces, and destabilize NATO. Moscow’s concern over a security environment in which other nuclear-armed countries are not party to the INF Treaty may also be fueling the violation.72 That disadvantage is a main reason why Moscow has sought to multilateralize the INF Treaty.

In addition to denying U.S. allegations, Moscow has raised its own concerns about Washington’s compliance with the agreement. Russia charges the United States with the following practices: placing a missile defense launch system in Europe that can be used to fire cruise missiles, employing targets for missile defense tests that have similar characteristics to treaty-prohibited intermediate-range missiles, and developing armed drones that are seemingly equivalent to ground-launched cruise missiles.

In November 2016, the United States called a meeting of the Special Verification Commission (SVC), an implementing body established by the INF Treaty to resolve compliance issues. The meeting in Geneva was attended by Belarus, Kazakhstan, Russia, Ukraine, and the United States. There, the United States provided detailed information to Moscow about its allegations of Russian noncompliance.73 The meeting yielded little progress toward resolving the compliance dispute. A second meeting of the SVC took place from December 12-14, 2017, but little information from that session has so far emerged.

The 2017 State Department compliance report repeats past accusations of Russian treaty noncompliance. It claims that the United States has provided Russia with information on the offending missile, such as details regarding the internal designator for the mobile launcher chassis, names of companies involved in developing and producing the missile and launcher, history and coordinates, and documented Russian efforts to obfuscate the program.74 The Russian Foreign Ministry responded to that report by reiterating a complaint it has made in the past that Washington had provided only “odd bits and pieces of signals with no clarification of the unfounded concerns.”75

Washington’s reluctance to provide explicit detailed evidence—including evidence it claims to have already given to Russia—has stymied productive discussion around resolving the compliance dispute. Ultimately, compliance concerns only heighten feelings of distrust on both sides. Without a solution for adequately addressing each side’s concerns—and returning Russia to compliance—it will be difficult for Moscow and Washington to make progress on other arms control issues.

On December 8, 2017—the 30th anniversary of the signing of the INF Treaty—the Trump administration announced what it called an integrated strategy for dealing with the Russian violation. The strategy reaffirmed the U.S. commitment to preserving the treaty and said the United States would (1) continue efforts to seek a diplomatic settlement of the Russian violation, including through the Special Verification Commission; (2) begin research and development on options for conventionally-armed intermediate-range ground-launched missile systems; and (3) impose economic sanctions on Russian entities that had taken part in development and production of the SSC-8.76

To extend or not to extend New START?

Aggregate data from September 2017 demonstrates that Russia has decreased its deployed strategic warheads by 235 in the past 12 months. Russia now has 501 deployed delivery systems and 1,561 deployed strategic nuclear warheads—only 11 warheads over the New START limit of 1,550 warheads.

Both countries are on track to fulfill New START limits by the February 5, 2018 implementation deadline, and there are no indications of either side straying from their obligations. In December 2017 Russian Ambassador to the United States Anatoly Antonov confirmed that Russia would meet its New START limits on schedule.77 As the deadline approaches, Russia has signaled interest in commencing talks on extending the treaty. The Trump administration has yet to respond to these overtures.

Trump’s ambivalence toward New START and efforts by Congressional Republicans to link its extension to resolution of the INF Treaty dispute mean that the treaty could expire in 2021 with nothing to replace it—a dire result.

Third-Country nuclear forces

Although other nuclear-armed countries have arsenals amounting to less than five percent of the size of the Russian and American arsenals, Russia still seeks the institution of limits on these arsenals and the inclusion of other nuclear countries in the arms control regime. In fact, even during INF Treaty discussions, Moscow strongly advocated for extending negotiations to UK and French forces, and continued to call for the inclusion of France and the United Kingdom in subsequent arms control talks with Washington.78 In 2013, the Kremlin advocated for the multilateralization of future arms reductions. At the nuclear Nonproliferation Treaty Review Conference in 2015, the Russians stated that multilateral negotiations among all nuclear-armed states are necessary to make progress on disarmament.79 Russia has yet to table a specific proposal for expanding the arms control process.

The United States does not believe that the relatively small size of third-country nuclear forces warrants inclusion in the next round of arms reductions. It is possible that the United States would be open to multi-lateralization in the future, if and when the size of U.S. and Russian nuclear arsenals has been more significantly reduced. But at the present time, this issue is yet another on the list of disputes hampering U.S.-Russian cooperation.

U.S. missile defense in Europe

Russia has expressed strong objections to U.S.-NATO missile defense systems in Europe. Moscow worries that the European Phased Adaptive Approach (EPAA) could challenge the strength of Russia’s nuclear deterrent, especially after future modernization projects are completed.

Putin remarked in 2016 that “we were assured that the missile defense system and its European segment were designed to protect against Iranian ballistic missiles. However, we know that the situation with the Iranian nuclear issue was resolved…and nevertheless, work on a [U.S.] missile defense system continues.”80 Kremlin officials have also claimed that U.S. missile defense systems lower the threshold for nuclear use. Russian Foreign Minister Sergey Lavrov said in 2017, “the anti-missile umbrella may increase the illusion of invulnerability and impunity and lead to temptation of taking unilateral steps in the resolution of global and regional problems, including the reduction of threshold of nuclear weapons use.”81

Incentives for Russian engagement on arms control

The current tensions in the U.S.-Russian relationship would seem to preclude agreement on a major new arms control accord in the near term. But resuming an arms control dialogue with Washington should be attractive to Moscow for many reasons.

First, participating in arms control efforts with the United States cements Russia’s status as a great power. By being party to treaties that enshrine Russia and the United States as equal actors, Russia can portray itself as a global influencer on par with the United States.

Secondly, the verification provisions contained in treaties like New START allow Russia to monitor U.S. nuclear forces and then factor that knowledge into nuclear planning. If Washington and Moscow were to fail to agree to extend New START, Russia would likely be displeased with the loss of limits and transparency on U.S. forces.

Thirdly, active participation in the arms control regime benefits Moscow during a time of economic uncertainty and unrest at home. Arms control reduces the need to finance expansive nuclear modernization projects, which frees funds for use elsewhere.

Finally, Russian military doctrine explicitly declares a commitment to arms control and nonproliferation. To be true to its doctrine and legacy of bilateral nuclear cooperation, Russia must reengage with the United States on nuclear risk reduction.

Recommendations for U.S. policy

The poor state of the U.S.-Russian nuclear relationship demands prioritizing measures that are feasible in the near-term in order to build a productive, durable dialogue on arms control. These measures include improving the NATO-Russian relationship, resolving the INF Treaty dispute, and extending New START. Ultimately, engaging in meaningful talks on strategic stability between the United States and Russia must be a priority for Washington if it wishes to heal its nuclear partnership with Moscow.

Strengthen the NATO-Russia relationship

Russia is undeniably anxious about the expansion and conventional force superiority of NATO, which may be driving increased Russian sabre rattling, emphasis on nuclear weapons, and even the decision to test and deploy a GLCM prohibited by the INF Treaty. The NATO-Russian question begs for resolution.

Reviving and expanding channels for NATO-Russian communication could mitigate Russian unease. Communication is essential in order to prevent dangerous military incidents, especially in the Baltic region where tensions are extremely high. Preventing incidents will help to prevent unintended escalation—a critical need, given concerns about the possible Russian use of nuclear strikes to turn the tide of conventional conflicts. Establishing direct military contacts and independent bodies that assess and respond to military confrontations could help prevent conflict.82

Russia and NATO must implement mutual restraint measures, such as those laid out in the NATO-Russia Founding Act (NRFA),83 which could alleviate concerns on both sides of the border. The NRFA should be reviewed and updated to address current needs. The NATO-Russia Council is one possible forum for dialogue, but it might be more useful to establish a similar body that is solely focused on nuclear-related matters. Either way, it is critical that there be a space for Russian and NATO representatives to openly discuss the factors affecting security and strategic stability.

The two sides should prioritize options to resolve destabilizing force imbalances, particularly in the common border area. Their discussions should also explore regulations on tactical nuclear weapons, which have not yet been included in the bilateral arms control process. NATO could also reaffirm its commitment under the NRFA to carry out defense activities by “ensuring the necessary interoperability, integration, and capability for reinforcement rather than by additional permanent stationing of substantial combat forces.” Finally, a decision by Washington to unilaterally reduce the size of the U.S. nuclear arsenal could push Moscow to reevaluate the size and scope of its next SAP.84

Resolve the INF Treaty dispute

The preservation of the INF Treaty is a crucial safeguard against the advent of a destabilizing arms race in the region. Therefore, Washington and Moscow must urgently address their disagreement regarding the treaty compliance of both countries. The United States should prioritize a diplomatic approach while working to ensure that Russia does not gain a military advantage from its violation.

The Deep Cuts Commission, a group of nuclear experts from the United States, Russia, and Germany, recently published a plan of action for addressing the INF Treaty dispute.85 The plan requests that Russia allow U.S. experts to examine the disputed Russian GLCM. If the United States concludes that the missile is indeed violating the treaty, the paper recommends convening the SVC or a similar independent panel of U.S. and Russian experts to discuss destroying the illegal missiles and launchers to return Russia to compliance.

The Deep Cuts Commission proposal suggests that Washington address Moscow’s concerns over U.S. compliance by negotiating revisions to the treaty language to account for drones and the use of booster stages in target missiles for ballistic missile defense. To satisfy Russian concerns, the authors recommend that the United States alter the land-based version of the Mk-41 launcher to clearly differentiate it from the Mk-41 systems placed on U.S. warships, and institute transparency mechanisms that allow Russia to verify that the launchers in Romania and Poland only contain SM-3 interceptors.

If the INF Treaty does collapse, Washington must ensure that Russia shoulders the blame. This means avoiding steps—such as building a new U.S. missile—that would simultaneously raise red flags among NATO allies and enable Russia to claim that the United States is cultivating nuclear instability.

Extend New START as soon as possible

Given the value of New START to U.S., Russian, and global security, the Trump administration should waste no time in accepting Russia’s offer to extend the treaty. If the treaty is allowed to lapse with nothing to replace it, there will be no limits on Russia’s strategic nuclear forces. Furthermore, the United States will lose the important monitoring and verification measures that allow Washington to keep an eye on the size and composition of Russia’s nuclear stockpile.

The deterioration of the U.S.-Russian relationship has only increased the value of New START. By verifiably capping U.S. and Russian deployed nuclear forces, the treaty bounds the current tensions between the two countries. This is especially important because other key pillars of the U.S.-Russian arms control architecture, like the broader bilateral relationship, are under siege. Failing to respond to Moscow’s invitation to discuss an extension of New START would be a major missed opportunity to ensure continued stability and predictability in the strategic relationship.

Make the most of strategic stability talks

During the Cold War, the Americans and Soviets understood “strategic stability” to mean a security environment in which neither side had an incentive to launch a nuclear first strike. To achieve that end, they collaborated on implementing measures to govern strategic nuclear weapons, missile defense, and air defense.

It is urgent that Washington and Moscow resume such discussions, beginning by agreeing on a shared definition of “strategic stability” to meet the current threat environment. To do so likely entails expanding the agenda of the talks, which should feature key arms control agreements, namely the INF Treaty and New START, as well as missile defense, third-country nuclear forces, and advanced conventional weapons. Without a renewed commitment to strategic stability talks, it will be difficult to improve nuclear cooperation between Russia and the United States.

The first round of renewed U.S.-Russian strategic stability talks began September 12, 2017 in Finland. Following the meeting, U.S. State Department spokeswoman Heather Nauert said that “the discussions provided both sides with an opportunity to raise questions and concerns related to strategic stability and also to clarify their positions on that matter.” The two delegations agreed to continue implementing New START arms reductions to meet the February 2018 deadline. Conversations focused on extending New START will need to follow quickly if such an extension is to be achieved.

It is important that this round of talks yield other rounds in the near future. Although Lavrov commented pessimistically in October 2017 that the global community should not expect “considerable results in the foreseeable future”86 from the U.S.-Russian strategic stability talks, the very resumption of dialogue is a significant step forward. An important outcome of the talks would be a reaffirmation by the leaders of Russia and the United States of the 1985 declaration made by U.S. President Ronald Reagan and Soviet Leader Mikhail Gorbachev that “a nuclear war cannot be won and must never be fought.”

Conclusion

The United States and Russia must commit to continual dialogue if they wish to address the different perceptions and misperceptions on both sides of the relationship that are harming nuclear cooperation. Even in the bleakest moments of the Cold War, Washington and Moscow were able to cooperate on arms control. If both countries put aside their differences to embark on further nuclear force reductions, they could reduce threats and save billions of dollars. Healing relations and enhancing national and global security requires productive discourse and true dedication to reducing nuclear weapons.

Washington cannot control Moscow, but it can formulate smart policy in regard to its nuclear forces and diligently seek tough and pragmatic cooperation with the Kremlin. To make that possible, the Trump administration must articulate a clear policy toward Russia, as well as strategies to reduce nuclear risks. Congressional support will be necessary to achieve these goals. Rather than hasten the unraveling of several longstanding nuclear risk reduction efforts, the Trump administration and Congress should maintain and reinforce existing arms control and nonproliferation measures.

Finally, American and Russian officials must tone down harsh rhetoric and capitalize on issue areas where they do agree. Unfortunately, the internal politics and foreign policies of both countries continue to shrink potential areas of cooperation. But the relationship has weathered hazardous tensions and even near-catastrophes in the past, with Washington and Moscow able to maintain nuclear cooperation during their darkest days. Today’s leaders must learn from their predecessors and prioritize nuclear risk reduction, or face a more uncertain and dangerous future.

The Complex and Increasingly Dangerous Nuclear Weapons Geometry of Asia

Description: 

Asian states Pakistan, India, China, and North Korea comprise four of the world's nine nuclear-armed states. The interconnections of these countries must be considered to fully understand how nuclear nonproliferation can be influenced.

While much of the world’s attention is focused on efforts to halt the nuclear and missile tests of North Korea, the nuclear arsenals and ambitions of India, Pakistan, and China also pose significant dangers and deserve more attention.

The complicated nuclear weapons geometry of Asia extends from the subcontinent to the other side of the world. While Pakistan’s nuclear arsenal is designed to counter India’s conventional and nuclear forces, New Delhi measures its own nuclear weapons program against that of China. Beijing, in turn, judges the adequacy of its nuclear arsenal against the threat it perceives from the United States’ strategic offensive and defensive capabilities. And in its efforts to mitigate the ballistic missile threat from North Korea, the United States and its allies in the region are expanding their strategic and theater missile defense capabilities.

In order to fully understand how the pace and direction of nuclear proliferation can be influenced, the interconnections of these countries must be considered, along with the kinds of nuclear weapons they have at their disposal.

Resuming Negotiations with North Korea

Description: 

The window of opportunity to prevent North Korea from developing nuclear-armed ballistic missile systems is closing and Washington should explore every serious diplomatic overture from Pyongyang.

The window of opportunity to prevent North Korea from fielding nuclear-armed ballistic missiles is closing. Diplomatic engagement with North Korea has been scant in recent years. In response to Pyongyang’s nuclear and missile tests, the United States and other countries, through actions of the United Nations Security Council and independent policies, have adopted an approach of increasing political and economic isolation. Yet, during this time, Pyongyang has improved its nuclear weapons capability quantitatively and qualitatively.

The next presidential administration must prioritize reviewing and renewing Washington’s diplomatic approach to North Korea. With each successive nuclear and missile test, North Korea advances its knowledge and consolidates its capability. History has shown that it is far easier to convince North Korea to negotiate away a military capability it does not yet possess. Washington’s stated primary concern is a North Korean nuclear-armed intercontinental ballistic missile (ICBM). Pyongyang will achieve this capability if it is not reined in through a diplomatic agreement or understanding. Once Pyongyang achieves this status, the security balance in Asia will be disrupted and U.S. diplomats will be hard-pressed to convince North Korea to abandon the capability.

North Korea’s Nuclear Threat: How to Halt Its Slow but Steady Advance

In the first five weeks of 2016, North Korea twice defied UN Security Council resolutions designed to stem its pursuit of nuclear weapons. On January 6, it conducted its fourth underground nuclear test; on February 7, it launched a satellite into space for the second time. These two events provided a vivid reminder that North Korea continues to make progress mastering the technology needed for developing long-range ballistic missiles and arming them with nuclear warheads.

U.S. leaders have long sought to formulate and implement policies that would secure a denuclearized Korean peninsula, but these efforts have not been successful. U.S. political commentary on North Korea vacillates between taking at face value the regime’s exaggerated claims of technological prowess and reducing its leadership to cartoonish stereotypes.

A clearer understanding of North Korea’s motives and the current status of its nuclear and missile programs can lead to a more realistic strategy for enhancing U.S. security. That strategy would involve using enhanced sanctions as leverage for achieving a halt in North Korea’s nuclear and missile testing and production of fissile material, but this can only happen through negotiations.

The P5+1 (China, France, Germany, Russia, the United Kingdom, and the United States) have finalized a comprehensive nuclear agreement with Iran that will verifiably block Iran's pathways to nuclear weapons development--the uranium-enrichment route and the plutonium-separation route--and guard against a clandestine weapons program. We assess that the final agreement will be a net-plus for nonproliferation and will enhance U.S. and regional security.

This two-page Iran Nuclear Policy Brief examines the key provisions and benefits of a comprehensive nuclear deal with Iran.

Understanding the North Korean Nuclear Threat

As the 2015 Nuclear Nonproliferation Treaty (NPT) Review Conference continues in New York, the international community's failure to halt the spread of nuclear weapons to North Korea looms large. Unlike the four of the world's nine nuclear-weapon states that have shown some progress in reducing their nuclear arsenals, North Korea is working hard to expand its arsenal and make it more credible. Unlike six of the nine, which have either ratified the 1996 Comprehensive Test Ban Treaty or maintained a testing moratorium since the treaty was concluded, North Korea has conducted three underground nuclear tests, the only state to do so during the last 17 years.

Unlike the three nuclear-weapon states that never became parties to the NPT, North Korea signed the treaty, declared it was withdrawing, later pledged to denuclearize, and then reneged on its commitment.

The North's nuclear program today is out of control and accelerating, damaging both the NPT and international stability. Addressing this grim reality begins with an objective assessment of North Korea's actual nuclear capabilities and an acknowledgment that the Obama administration's "strategic patience" approach is not working.

Washington and Beijing must step up their efforts to revive the six-party process with the near-term goal of freezing Pyongyang's nuclear and missile programs, taking care to manage potential spoilers, Russia and the U.S. Congress.

Nuclear Cruise Missiles: Asset or Liability?

Description: 

The future of U.S. and Russian nuclear cruise missiles is at an inflection point.

The future of U.S. and Russian nuclear cruise missiles is at an inflection point. Russia's alleged testing of a ground-launched cruise missile has jeopardized not only the 1987 Intermediate-Range Nuclear Forces (INF) Treaty, but other bilateral nuclear agreements as well, adding further strain to the U.S.-Russian relationship.

The U.S. allegation and Moscow's three counter charges should be resolved with the help of the treaty's Special Verification Commission, which was explicitly designed to deal with compliance issues. But the two countries need to take a broader look at nuclear cruise missiles.

New strategic cruise missiles are part of an unaffordable drive by Washington and Moscow to simultaneously modernize all three legs of their strategic arsenals. Given the increasingly marginal role that nuclear cruise missiles play in ensuring a U.S.-Russian balance and their destabilizing impact when deployed by emerging nuclear powers such as Pakistan, it is time to consider doing away with them entirely.

Iran Nuclear Policy Brief: Breaking Down Iran's Breakout Capacity

As efforts intensify to bring the Iran nuclear negotiations to a successful conclusion by November 24, the issue of breakout continues to occupy center stage. Setting limits on Iran’s nuclear program to dissuade the leaders in Tehran from breaking out of the nuclear Nonproliferation Treaty and possibly building nuclear weapons is a central objective of the P5+1 powers (China, France, Germany, Russia, the United Kingdom, and the United States).

Consideration of the effect of agreed limits on the time it would take Iran to build nuclear weapons is, therefore, a necessary step in formulating the P5+1 negotiating position, but is not sufficient for navigating the appropriate course toward a comprehensive agreement.

Relying on the narrow definition of the term “breakout”—obtaining enough weapons-grade uranium gas for one bomb—does not fully capture the path that would have to be traveled. It is also necessary to consider “effective breakout”—the time needed to build a credible nuclear arsenal—in order to ensure that the proper balance between verification and limitations can be achieved.

A Win-Win Formula for Defining Iran's Uranium-Enrichment Capacity

As negotiators prepare to resume talks over Iran's nuclear program, they face a formidable task: to bridge the remaining gaps and reach a comprehensive nuclear deal by November 24. Perhaps the most difficult issue Iran and the P5+1 (China, France, Germany, Russia, the United Kingdom and the United States) must resolve is how to define the size and scope of Iran's uranium enrichment program.

To achieve a win-win outcome the two sides must develop a creative, technically sound formula that increases the time it would take for Iran to enrich uranium to weapons grade, while still providing Tehran with a modest program that allows domestic production of enriched uranium to contribute to fueling future civilian reactors and allows research and development to advance centrifuge technology.

In collaboration with the International Crisis Group, the Arms Control Association has developed a proposal to define Iran's uranium enrichment program in a manner that meets the fundamental concerns of both Tehran and the P5+1. The proposal is the product of feedback from a number of technical and political experts. While this may not be "the solution" to the enrichment puzzle, the proposal offers constructive options for the negotiators to consider.
