A tentative F-35A force estimate starts near forty-eight aircraft

How many F-35As are needed for a viable force, and is F-35A or Typhoon the better interceptor?

The tentative estimate is roughly 48 F-35As, assuming two-thirds availability. Typhoon is judged probably slightly better as an interceptor, and the A-model purchase is proposed as additional to the carrier-capable Bs.

Typhoon is judged probably slightly better as an interceptor. For a viable F-35A force, particularly one with a nuclear mission, the suggested minimum is roughly 48 aircraft. Assuming two-thirds availability, that would leave about 32 airframes for two available squadrons and the force integration group. This is an illustrative availability calculation rather than a stated operational requirement. Taking all 48 from intended F-35B purchases would leave too few carrier-capable aircraft, so a force on this scale would need additional procurement.
