Britain’s disclosure last year of the size of its nuclear weapons stockpile shows, when combined with official information released earlier, that its Cold War nuclear stockpile was bigger than previously thought – more than 500 nuclear warheads in the 1970s.
Since then, Britain has reduced its stockpile by more than half to approximately 225 warheads and has decided to reduce it further to 180 warheads by the mid-2020s, a reduction of two-thirds compared with the Cold War level.
Modernization and continuous deployment at sea continues, however, and current plans might ironically lead to an increase in the number of warheads carried on each operational missile.
This and more is described in our latest Nuclear Notebook published in the Bulletin of the Atomic Scientists.
