To say “helped out” is a little ungenerous. I think the Marine Corps genuinely enjoy working with the Royal Navy, as the hon. Gentleman acknowledges, and we have a very close working relationship with them. We have committed to 48 F-35s, which will arrive by 2025. We have not announced how many, but we will be buying more F-35s. We will take that decision by 2025, when the full complement of 48 have arrived.
