I'm sure that I read an account of the RN's role in the development of shipboard ops in the F4U Corsair. It seems that the USN had difficulty with bringing the F4U aboard carriers due to the poor visibility over it's long nose in the approach attitude. Consequently, the F6F Hellcat became the preferred equipment for the carrier fighter squadrons, whilst the F4U was issued to the USMC for mainly land-based operations. When the FAA got hold of the Corsair they applied the hard-learned lessons of the Seafire and adopted a curving approach to the deck, giving the pilot much better visibility. This technique dramatically reduced the Corsair's landing accident rate and was adopted by the USN, allowing F4U to give distinguished service right through the Korean War and outliving the rival F6F.
