Question to the Ministry of Defence:
To ask the Secretary of State for Defence, what costings have been made for the acquisition of new nuclear weapons up to a total of 260 as announced in the Integrated Review.
The Integrated Review announced the UK will move to an overall nuclear weapon stockpile of no more than 260 warheads. This is a stockpile ceiling and we will remain deliberately ambiguous about the exact number of warheads to avoid simplifying the calculations of potential adversaries. The cost estimates for the wider warhead programme are undergoing consideration as part of Departmental budgeting.
