F4U also had the slight issue that the pilot was so far from the nose you couldn't see the carrier on finals. The RN actually took it to sea before the USN as a) they were desperate for modern fighters and b) they'd already mastered the curved final approach with the Seafire as that had the same problem.
The USAF did also use the originally designed for the USN A-7 Corsair, although the USMC didn't going for the Harrier instead. In the UK the RN and RAF both used the Buccaneer, Harrier, Phantom, and Venom.
