Did the Fleet Air Arm dislike American lend-lease carrier aircraft because they did not match British requirements?
Short answerNo. It valued their availability and performance, then adapted them to British carrier operations and doctrine.
NotesThe Fleet Air Arm welcomed American Avengers, Hellcats, Wildcats, and Corsairs. British naval aircraft repeatedly lost their intended engines to Air Ministry priorities, forcing redesigns and delaying production. Imported aircraft offered strong performance even when they did not match every British doctrinal requirement. The Royal Navy adapted them to its own needs, a practice described as Anglicizing the aircraft. British work also extended to their engines, with Bristol credited with improvements to Wright Cyclones.
