1) The performance envelope minimally relevant given the current state of missile technology. 2) Trillions haven't been spent on the F-35 as others have mentioned. Those numbers are outlays for the total of all R&D + procurement + maintenance for several decades + any specialized equipment needed for maintainence + some other things I can't remember off the top of my head 3) You're years behind the military on this. One of the ideas behind the F-35 is to be able to start integrating unmanned vehicles commanded by the F-35, and be a stepping stone for developing full manned-unmanned teaming for generation 6 fighters.
