To ask the Secretary of State for Defence, what estimate he has made of the cost of building a new replacement warhead.
30 June 2021
As the replacement warhead is in its early preliminary phases it is too early at this stage to provide a cost estimate. I am however able to provide information relating to completed financial years. The Ministry of Defence spent £116 million up to the end of the financial year (2018-19). A total of £98 million was spent on the Replacement Warhead readiness phase over the subsequent two financial years (2019-20 and 2020-21).
