The British Fleet Air Arm (FAA) received 1,263 F6Fs under the Lend-Lease Act; initially, it was known as the Grumman Gannet Mark I. The name Hellcat replaced it in early 1943 for the sake of simplicity, the Royal Navy at that time adopting the use of the existing American naval names for all the U.S.-made aircraft supplied to it, with the F6F-3 being designated Hellcat F Mk. I, the F6F-5, the Hellcat F Mk. II and the F6F-5N, the Hellcat NF Mk. II. They saw action off Norway, in the Mediterranean, and in the Far East. Several were fitted with photographic reconnaissance equipment similar to the F6F-5P, receiving the designation Hellcat FR Mk. II.Green 1975, p. 93.
