UK May Host U.S. Nuclear Weapons Again

The United Kingdom may host U.S. nuclear weapons on its territory for the first time since their complete withdrawal 15 years ago, a move that Russia stated would escalate already high nuclear tensions in Europe.

If the United States redeploys nuclear weapons to the United Kingdom for the first time in 15 years, they would be in addition to the 225 nuclear warheads that the UK has available for its submarine-launched ballistic missiles such as the Trident ballistic missile on this Vanguard class submarine.

The United States often employs the term “surety” when referring to the safety and security of U.S. nuclear weapons.

Russian Foreign Ministry spokesperson Maria Zakharova denounced the potential move on Sept. 5, saying that “[i]f this step is ever taken, we will view it as escalation, as a step that would take things in a direction that is quite opposite to addressing the pressing issue of pulling all nuclear weapons out of European countries.” Meanwhile, Russia purportedly has been transferring tactical nuclear weapons to Belarus.

The UK nuclear arsenal consists of an estimated 225 nuclear warheads for submarine-launched ballistic missiles. The U.S. nuclear weapons that potentially are headed for the UK most likely would be B61-12 gravity bombs.

Currently, the United States is believed to deploy an estimated 100 B61gravity bombs across five other European countries—Belgium, Germany, Italy, the Netherlands, and Turkey—under the NATO nuclear sharing mission. Washington withdrew an estimated 110 B61 bombs from Lakenheath in 2008.

A spokesperson for the UK Defense Ministry told The Guardian on Aug. 29 that “it remains a long-standing UK and NATO policy to neither confirm nor deny the presence of nuclear weapons at a given location.”

Kristensen and Korda offered a possible explanation for what looks like the return of U.S. nuclear weapons to the UK, suggesting that perhaps “the United States is currently preparing the infrastructure at RAF Lakenheath to allow the base to potentially receive nuclear weapons in the future or in the midst of a crisis, without necessarily having already decided to permanently station them there or increase the number of weapons currently stored in Europe.”

Marion Messmer of Chatham House in the UK suggested another interpretation. “There has also been a fairly sensitive discussion since the coup attempt in Turkey in 2016, and the long-running civil war in Syria, over whether the nuclear weapons which are assumed to be stationed in Turkey are safe there,” she told Arms Control Today on Sept. 19. “So, another potential explanation for this investment in Lakenheath might be that when the nuclear weapons are next going to be serviced, they won’t be replaced in Turkey, and will instead be stationed in the UK.”

Plans call for the dormitory construction to begin in June 2024 and finish in February 2026. The 2024 budget allotted $50 million for the project. Meanwhile, NATO is overseeing infrastructure and security upgrades at nuclear weapons storage sites in Europe, including Lakenheath, according to 2023 budget documents.

The activities at Lakenheath coincide with the anticipated arrival in Europe this year of new B61-12 bombs, which are replacing the B61-3/4 bombs, and amid the phased delivery of the nuclear-capable F-35A Lightning II jets to a U.S. Air Force squadron stationed at the UK base. The first aircraft of a planned 24 arrived in December 2021.
