History: In 1936 the US Navy evaluated a number of designs which were competing to be the Navy's new carrier-based fighter. Grumman built a design which, after several re-designations and airframe modifications, won the contract and eventually became the F4F Wildcat. The prototype, the XF4F-2, first flew on 2 September 1937. The prototype of an improved version, the XF4F-3, was renamed the F4F and was ordered by the Navy in August of 1939. The first five aircraft off the assembly line were sent to Canada, with the next 90 (designated "Martlet Mk I" going to the 804 Squadron of the Royal Navy's Fleet Air Arm where, in December 1940, two Martlets made history by becoming the first American-made aircraft to down a German plane in WWII.

The first US Navy F4F-3 was flown on 20 August 1940, powered by a Pratt & Whitney R-1830 engine with 1,200 horsepower. The subsequent F4F-4, incorporating several improvements including folding wings, six guns and self-sealing fuel tanks, was delivered in November 1941. It was then that the name "Wildcat" was first given to the F4F. As war raged around the world, the Wildcat's reputation and utilization grew immensely. It flew with the US Navy and US Marines in all of the major Pacific battles, and in North Africa with the Navy.

In mid 1942, Grumman realized that it needed to concentrate on the production of its new F6F Hellcat fighter, and so it contracted with the General Motors Company to build the Wildcat under the designation FM-1. The first FM-1 flew on 31 August 1942, and over 1,150 of them were produced, hundreds of which went to the Fleet Air Arm as the "Martlet Mk V." General Motors next developed an improved version, called the FM-2 ("Wildcat Mk VI" in the Fleet Air Arm), which was powered by a Wright R-1820 engine with 1,350 horsepower. It featured a taller vertical tail than the FM-1. Over 4,700 FM-2s were built before the Wildcat was eclipsed by the more capable fighters which appeared later in the war.
