The f14s mission went away. If you are worried about a sophisticated opponant attacking your carrier, a heavy fighter-interceptor is no longer a defense against modern missiles. It was a great plane for a job that no longer exists.

If you are really into weapon history, the Phoenix missile was originally meant for an airforce super interceptor, think an armed version of the SR-71. It was meant to shoot down Valkyrie-class supersonic bombers carrying nuclear weapons. That scenario never developed, but the navy took the missile for blue water battles defending carriers. Arguably, the f-14 was only so big and powerful because it needed to haul a radar capable of servicing the missile. Phoenix was never useful in mixed environments where friendlies might be in range because that wasn't part of the original intention. It was meant for killing big/fast things approaching in open sky, not picking out Migs over Syria.
