UK reverses disarmament policy and decides to increase nuclear arsenal By TPN/Lusa, in News, UK · 16-03-2021 15:39:00 · 1 Comments The British Government has decided to increase the ceiling of its nuclear arsenal for the first time since the fall of the Soviet Union, as part of its strategic review of security, defence and foreign policy published on 16 March. The UK will raise the ceiling on its stockpile of nuclear warheads from 180 to 260, an increase of about 45 percent, according to the document, which will be presented in Parliament by the Prime Minister, Boris Johnson. The decision ends a policy of gradual nuclear disarmament that has been ongoing for about 30 years, although it is unusual to publicly reveal the exact number of warheads or missiles.
