Is it true that the F-14 cannont carry 6 AIM-54s and land on a carrier?
IIRC, this is true of the TF-30 engined ones, but the
F-110 engined ones can carry 6.
It was limited by go around capability, and the greater
thrust and throttle response of the F-110 made a difference.

Actually, it was a function of maximum landing weight. That was raised
later in the program (some of which would be absorbed F110 engine weight
IIRC), but 6 Px would leave little (any?)left for fuel in any case.
