Question to the Ministry of Defence:

To ask the Secretary of State for Defence, whether the Re-entry Systems Options project has concluded its work.

As of the end of the last financial year (March 2017), the Ministry of Defence had spent £100.7 million on studies to inform the decision on whether to refurbish or replace the existing warhead.

This figure consists of £93.7 million on technology studies to support refurbishment of the current system and explore options for a potential future warhead and £7 million on studies to support the decision whether to refurbish or replace the existing warhead.

Studies related to Re-entry Systems Options to determine the best approach to be taken are continuing.
