Question to the Ministry of Defence:

To ask the Secretary of State for Defence, how much funding has been (a) allocated and (b) spent on the Global Combat Air Programme Tempest programme as of 6 February 2024.

The March 2021 Defence Command Paper reaffirmed that that we will invest more than £2 billion in the Future Combat Air System (FCAS) out to 2025, and we have spent over £1.8 billion so far. This is part of a budget of over £12 billion over the next 10 years. The amount that we ultimately invest will be determined at future decision points.

Furthermore, the Ministry of Defence has invested over £1.1 billion in R&D through the Future Combat Air System Technology Initiative (FCAS TI), with a further £600 million from our Team Tempest industry partners to date.
