Bet F15 outlives F22 and F35. I’t versatile, fast, and comparatively economical. Who cares if they can see you coming if they can’t do anything to stop you?

The winner for longevity is still the B-52.

....don’t forget the venerable KC-135.....still chugging along after some 70 years or so....??

And the C-130 and the U2.
