I always wondered why they couldn’t have just used the F-22 for both the air superiority role it was originally designed for and the multi-purpose role the F-35 was made for. The F-22 is more capable in every way, and more survivable with dual engines. They would have needed to figure out vertical take-off/landing version of the F-22 but I’m sure that was not impossible.
It may have looked more expensive on paper with ideal assumptions to produce lots of expensive F-22s instead of a few F-22’s and lots of cheaper JSFs. But in practice I bet the costs would have equalized, due to the increased volume of F-22s and the development of extensive institutional knowledge of that airframe - from manufacturing to maintenance to piloting/operating.
