The Marines were strong armed into buying the F-14, ~70 birds, in a quid pro quo by the Navy for getting the Harrier; VMFA-122 was supposed to get them initially. The Marine Corps never wanted them, choosing to stick with the Phantom II until the F-18 became available. Finally, after continued bitching by the Commandant, Schlesinger canceled the buy in July of '75. Several Marines actually became qualified F14 pilots/RIOs and even deployed with Navy VFs. Saw a 70s Marine Corps recruiting poster at Whidbey Island in 1982 that had a picture of an F-14 on it.
