I don't know the planned date but I think F-35's will start manning up in about another ten years if not sooner. Versions will be A: vanilla model, replacing USAF F-16's. B: STOVL capable replacing USMC and UK AV-8 Harriers, and C: Carrier capable replacing Navy Hornet C's. Remember, the carrier version will need more than just a tailhook but folding wings, heavier landing gear and a re-inforced airframe. That's what I've read anyway.
Anybody hear anything about the gun? 27mm Mauser chain gun is supposed to be the next big thing. All I ever read about was that Boeing's was modular, along with the parts that made it go either supersonic or STOVL, but never on the same flight. No wonder it lost.
Any info on the F-35's gun setup? A full time gun would be nice.
