Russia is pursuing a new and more advanced anti-satellite (ASAT) weapons system that would violate the Outer Space Treaty, according to Biden administration officials.

National Security Advisor Jake Sullivan briefed select members of Congress on new U.S. intelligence about the system on Feb. 15, and later that day, White House spokesperson John Kirby confirmed to reporters that the system is “related to an anti-satellite weapon that Russia is developing.”

Although it is not an “active capability that has been deployed,” Kirby said that the new system “would be a violation of the Outer Space Treaty, to which more than 130 countries have signed up to, including Russia.”

Article IV of the treaty expressly prohibits countries from deploying “in orbit around the Earth any objects carrying nuclear weapons or any other kinds of weapons of mass destruction, install[ing] such weapons on celestial bodies, or station[ing] such weapons in outer space in any other manner.”

Kirby said that “our general knowledge of Russian pursuit of this kind of capability goes back many, many months, if not a few years. But only in recent weeks has the intelligence community been able to assess with a higher sense of confidence exactly how Russia continues to pursue it.”

“We found out there was a capacity to launch a system into space that could theoretically do something that was damaging,” President Joe Biden told reporters at the White House on Feb. 16. “Hasn’t happened yet, and my hope is it will not.”

According to a CNN report that same day, officials familiar with the intelligence assessment confirmed that the Russian ASAT system under development involves a nuclear explosive device that would produce not only a massive nuclear-driven blast wave and a surge of radiation, but also a powerful electromagnetic pulse that could destroy, blind, or disable other satellites in orbit over a wide zone.

Such a weapon could pose a threat to U.S. and allied military communications, early-warning, and intelligence-gathering satellites if it were to become operational. It also would pose a threat to thousands of other space-based assets in orbit operated by dozens of other countries and commercial entities.

During the Cold War, the Soviet Union and the United States experimented with various types of ASAT weapons systems concepts, including the use of nuclear explosions to destroy objects in space and the production of beams of directed energy to destroy or disable enemy satellites.

Between 1958 and 1962, the United States carried out a handful of very high-altitude nuclear detonations, including the massive 1.4-megaton Starfish Prime test that occurred 250 miles above the Pacific Ocean and demonstrated the potential of nuclear detonations as ASAT weapons. The Soviets conducted a series of high-altitude nuclear test explosions over Kazakhstan between 1961 and 1962.

These test explosions produced a surge of free electrons that created X-rays capable of severely damaging electronic components and computer systems on the ground and in low earth orbit, an electromagnetic pulse that can disable unprotected electrical components on satellites, and a nuclear flash that can blind optical sensors on reconnaissance satellites. The Starfish Prime nuclear test explosion also produced radiation belts that lingered for months, disabling eight of the 24 satellites that were in orbit at that time, according to a 2022 report by the American Physical Society.

In 1963, U.S. and Soviet negotiators concluded the Limited Test Ban Treaty, which prohibits nuclear test explosions in the atmosphere, and in 1967 the Outer Space Treaty.

As Jaganath Sankaran wrote in Arms Control Today in 2022, Russia has been pursuing a range of ASAT system capabilities for more than a decade, including co-orbital ASAT weapons capabilities in the geostationary orbit where most military command-and-control satellites operate, as well as ground-based lasers and a range of satellite jamming systems to deny and degrade the capacity of weapons that rely on satellite-enabled information.

In 2021, Russia conducted an ASAT weapons test on one of its own satellites, breaking it into more than 1,500 pieces of debris, which can pose a serious threat to other objects in orbit. China, India, and the United States also have demonstrated ASAT missile capabilities.

But none of these systems involved nuclear explosive devices. Today, there are approximately 9,500 active satellites in orbit and two crewed, orbiting space stations. One or more nuclear weapons explosions in orbit would create far more indiscriminate damage than the 1962 Starfish Prime nuclear test, and the loss of satellite services would affect significant commercial, military, communications, and navigations systems on Earth.

On Feb. 15, Kremlin spokesperson Dmitry Peskov dismissed the claim that Russia was pursuing a nuclear-armed ASAT weapons capability as a “malicious fabrication," but on Feb. 16 he told RIA Novosti that Russia is ready to discuss the issue “if there are such initiatives from the American side.”

On Feb. 15, Kirby said, “We are in the process with engaging with Russia about this.” He said that Biden “has directed a series of initial actions, including additional briefings to congressional leaders, direct diplomatic engagement with Russia, with our allies and our partners as well, and with other countries around the world who have interests at stake.”

On Feb. 20, Russian President Vladimir Putin commented on the topic of nuclear weapons in space during a working meeting in Moscow with Russian Defense Minister Sergei Shoigu.

“Our position is clear and transparent: we have always been categorically against, and are now against, the placement of nuclear weapons in space,” Putin said, according to Kommersant. “On the contrary, we call for compliance with all agreements that exist in this area and proposed to strengthen this joint work many times over.”

The U.S. Air Force notified Congress on Jan. 18 that the new Sentinel intercontinental ballistic missile (ICBM) would cost 37 percent more than expected and take about two years longer than planned to build and deploy.

The cost per unit for the Sentinel system originally was projected to be $118 million and now is estimated at $162 million, putting the projected total program cost at roughly $120 billion over the next decade, up from an estimated baseline of $96 billion, the Air Force told Defense News.

The expected delay of the system’s initial operating capability likely will result in greater sustainment costs to keep the existing fleet of Minuteman III ICBMs operational.

The projected overrun would put the new missile system in “critical” breach of the Nunn-McCurdy Act, a law designed to prevent major cost overruns for weapons systems, a chronic problem plaguing the Pentagon.

There are two levels of breaches under the act. A program is in significant breach when the program unit cost increases by 15 percent of the current baseline or 30 percent over the original cost estimate. A critical breach occurs when the cost increases by 25 percent of the current baseline or 50 percent of the original estimate.

In 2020, Northrop Grumman was awarded a sole-source $13.3 billion contract for engineering and manufacturing Sentinel missiles to replace the current arsenal of 400 deployed Minuteman III ICBMs.

The Sentinel development program calls for acquiring 659 missiles, updating 450 launch silos, and modernizing more than 600 facilities to “like new conditions,” according to Air Force Global Strike Command. (See ACT, May 2023.)

In 2020 the Pentagon estimated that the total cost of the next-generation Sentinel program, including decades of operations and support, could be as high as $264 billion. (See ACT, March 2021.) Taking the new cost increases into account, the total cost of the program over its planned 50-year life cycle could be as high as $300 billion, plus another $15 billion for the production of the new W87-1 warhead for the missiles.

Under the act, the Defense Department is required to report to Congress whenever a major defense acquisition program exceeds certain cost thresholds. The notification must include an explanation of the cost increase, changes in the projected cost, changes in performance or schedule, action taken or proposed to control cost growth, and prior cost estimating information.

In addition, the department must submit a new selected acquisition report containing the new status of the total program cost, schedule, performance, cost per unit, and cost breach information. The report on the Sentinel program is due to be submitted within 45 days after President Joe Biden submits his budget to Congress, now set for March 9.

With a critical breach, the Office of the Secretary of Defense is required to conduct a root-cause analysis to determine what factors caused the cost increase.

Under the act, if the program is to continue, the defense secretary must certify no later than 60 days after the new selected acquisition report that the program is essential to national security, the new cost estimates are reasonable, the program is a higher priority than those whose funding will be cut to cover the cost increase, and a new management structure is in place to control additional cost growth. If the certification and requirements are met, the program will be allowed to continue.

At the Air Force Association forum on Feb. 11, Air Force Secretary Frank Kendall said that “nothing is off the table right now.… [W]e’re going to take a look at the totality of the [defense] budget” when addressing how to cover the additional $35 billion needed for the Sentinel program.

Rep. John Garamendi (D-Calif.), a member of the House Armed Services Committee and co-chair of the bicameral Nuclear Weapons and Arms Control Working Group, argued in a statement Jan. 18 that the overrun is “proof that we must look closely at our nation’s nuclear policies…[and] address our security needs without compromising fiscal responsibility.”

Some experts, such as Gabe Murphy, a national security policy analyst with Taxpayers for Common Sense, say that the United States should get rid of ICBMs entirely. “Whatever strategic value nuclear ICBMs may have held in the past, in our current security environment, they serve as little more than a bottomless pit…[into] which the Pentagon throws taxpayers’ hard-earned money,” Murphy wrote in an Feb. 11 essay for Stars and Stripes.

In 2016, former Defense Secretary William Perry wrote in The New York Times “that the United States can safely phase out” its land-based ICBM force. He argued that although the ICBM force is too costly and dangerous, submarine and bomber forces are highly accurate and thus are “sufficient to deter our enemies and will be for the foreseeable future.”

Despite the cost increases, congressional backers of the Sentinel program say it should go full-speed ahead. “Sentinel is absolutely necessary for the future of our nuclear deterrent. I’m committed to conducting vigorous oversight of the program and ensuring the Air Force follows through on making the necessary changes to address the cost overruns while continuing to advance the program,” House Armed Services Committee Chairman Mike Rogers (R-Ala.) said in a Jan. 19 press statement.

Others urged support for Sentinel whatever the cost. “Despite these challenges, abandoning or downsizing Sentinel isn’t an option. Our nation’s safety and prosperity depend on an updated and fully operational nuclear deterrent,” argued Sens. Roger Wicker (R-Miss.) and Deb Fischer (R-Neb.), the ranking members of the Senate Armed Services Committee and its strategic forces subcommittee, respectively, on Jan. 19 in The Wall Street Journal.
