Corruption along with a dollop of incompetence, plain and simple.
ALso the fact that the F22 is very much a one trick pony.
AKA Air Superiority and that it for that air frame.
Sure it can drop a set of bombs, but the F35 can do heavier bombs AND carry a set of AMRAAMs while stealthed AT LONGER RANGE.
The F22 is a good plane, problem was it came at the wrong time (peace divided) in a far too of a specialized, and limited role to excel like it should.
The F35 does have more range then the two PRIMARY PLANES it replaces.
The F16 without drop and CFT has a max combat range of 340 miles give or take twenty miles.
While the FA18 hornets in similar set ups are barely better at 390 miles combat range.
Compare to the F35b, the VTOL Lightning, the version with the worse range of the lot, Has 500 miles...
The other two versions are pushing 670 miles, basically 200 to 300 miles more range clean. And the F35 clean means 6 AIM120s or 2 Aim120s and two 2000 pound bombs in the damn bays.
OH and the F22 clean subsonic full endurance mode, maxs out at 590 miles in radius with supercruise dropping it down to 460.
Again this is the COMBAT radius.
AKA can go from the target, bugger around, and come back in this distance with an useful load without tanker support.
And the F35a/cs have more range the most of the fighters types in the FORCE! The only one that has more are the F-15E/EXs at about 880 miles.
Honestly the speed can be fix by adding a proper intake ramps instead of those speed bumps so it can properly use the full power of the engine, then it have some proper get up and go.
