Early model F-14A had no nose pitot:
... but they seem to have quickly acquired them sometime in the late 1970s. The Iranian F-14s have them, and it's quite hard to find a picture of an F-14 without a nose pitot.
This is the nose pitot that appears on the majority of F-14s:
I believe the nose pitot measures angle of attack, a measurement I would have thought was critical to a big carrier-based aircraft like the F-14 from the outset.
So, why were the nose pitots introduced, and what effect did it have on the nature of piloting an F-14?
