Development;- Designed as a biplane to continue Grumman's very successful F3F series of single seat carrier fighters, the XF4F-1 was replanned on the drawing board in the summer of 1936 as a mid wing monoplane. Though this machine, the XF4F-2, lost out to the Brewster F2A Buffalo, Grumman continued with the XF4F-3 with a more powerful engine and in early 1939 received a French Aeronavale order for 100, the US Navy following with 54 in August. The French aircraft were diverted to Britain and renamed Martlet I. Production built up with both Twin Wasp and Cyclone engines, folding wings being introduce with the R4R-4, of which Grumman delivered 1,169 plus 220 Martlet IVs for the Fleet Air Arm. Eastern Aircraft Division of General Motors very quickly tooled up and delivered 839 FM-1s and 311 Martlet Vs, the British name then being changed to the US name of Wildcat. Grumman switched to the Avenger, Hellcat and other types but made F4F-7 reconnaissance versions weighing 10,328lb and having 24 hour endurance as well as a floatplane version. eastern took over the final mark, the powerful and effective FM-2, delivering 4,777 of this type ( including 340 Wildcat VI) in 13 months. A Martlet I shot down a Ju88 on Christmas day 1940, and an F4F-3 of VF-211 destroyed a Japanese bomber at Wake Island on 9 December 1941. each event was the first of thousands of furious actions from this quite old fighter emerged with a splendid reputation. Wildcats were especially valuable for their ability to operate from small escort carriers, the pioneer work having been done with British Martlets based in November 1940 on the 5,000 ton captured German vessel Audacity on which a flat deck had been built. Noted for their strength and manoeuvrability, Wildcats even sank Japanese submarines and a cruiser.
