Ironically, the F-111 was the only model/mission of the TFX development effort to survive. The TFX was the '60s version of the F-35, except it also tried for the air superiority role the F-22 now fills.
Nominal peacetime is when the bureaucrats try to save money with a single weapon system that "can do everything" ... but it seldom does more than one thing well. The M14 rifle is another '50s example.
