Well, your memory does NOT serve, as the AIM-54 system most certainly WAS installed on Iranian F-14's, and they were supplied well in excess of 250 missiles.
Ya'all gotta remember, Iran under the Shah was vastly different than the Iran of today.
I sit corrected. Maybe I’m remembering something about after the fall of the Shah and the embargo of spare parts for the F-14. In any event, I went through Navy flight training with some of the Shah’s Boys, and we considered them to be laughingstocks.
