Question to the Ministry of Defence:

To ask the Secretary of State for Defence, (a) what definition his Department has set for initial operating capability for the Future Combat Air System; and (b) what are the estimated dates for (i) initial operating capability and (ii) full operating capability for the programme.

Work on the Future Combat Air System (FCAS) is progressing at pace, enabled by a digital-first approach that embraces new technologies, and early investment in Research and Development. We are targeting an in-service date of 2035. The definition set for initial operating capability is classified and I am withholding details as its disclosure would be likely to prejudice the capability, effectiveness, or security of the Ministry of Defence and the Armed Forces. FCAS initial operating capability is planned to provide a step-change to the capabilities it will replace, including Typhoon.
