Question
To ask the Secretary of State for Defence, pursuant to the increase in nuclear warheads announced in the Integrated Review on 16 March 2021, (a) how many extra Trident Missiles will be required, (b) at what cost and (c) by which date.
Answer
The UK has sufficient Trident II D5 missiles for its needs. The recent announcement in the Integrated Review to limit our overall nuclear weapon stockpile to no more than 260 warheads does not change this.
