One of the great under reported history of the early war years in the South Pacific was the saga of the Gruman FM2 "wildcat". As time and events unfolded during the war,and because of more faster and better fighters, the FM2 was assigned duty on small escort carriers from mid 1943 until the end of the war.

The Wildcat was generally outperformed by the Mitsubishi Zero, its major opponent in the early part of the Pacific Theater, but held its own partly because, with relatively heavy armor and self-sealing fuel tanks, the Grumman airframe could survive far more damage than its lightweight, unarmored Japanese rival. Many U.S. Navy fighter pilots also were saved by the Wildcat's ZB homing device, which allowed them to find their carriers in poor visibility, provided they could get within the 30 mi (48 km) range of the homing beacon.
In the hands of an expert pilot using tactical advantage, the Wildcat could prove to be a difficult foe even against the formidable Zero. After analyzing Fleet Air Tactical Unit Intelligence Bureau reports describing the new carrier fighter, USN Commander "Jimmy" Thach devised a defensive strategy that allowed Wildcat formations to act in a coordinated maneuver to counter a diving attack, called the "Thach Weave.

Note the size of the man in the cockpit to give you some reference as to how small this aircraft was.
Grumman's Wildcat production ceased in early 1943 to make way for the newer F6F Hellcat, but General Motors continued producing Wildcats for both U.S. Navy and Fleet Air Arm use. At first, GM produced the FM-1 (identical to the F4F-4, but with four guns). Production later switched to the improved FM-2 (based on Grumman's XF4F-8 prototype) optimized for small-carrier operations, with a more powerful engine, and a taller tail to cope with the increased torque.
From 1943 onward, Wildcats equipped with bomb racks were primarily assigned to escort carriers for use against submarines and attacking ground targets, though they would also continue to score kills against Japanese fighters, bombers and kamikaze aircraft. Larger fighters such as the Hellcat and the Corsair and dedicated dive bombers were needed aboard fleet carriers, and the Wildcat's slower landing speed made it more suitable for shorter flight decks.
In the Battle off Samar on 25 October 1944, escort carriers of Task Unit 77.4.3 ("Taffy 3") and their escort of destroyers and destroyer escorts found themselves as the sole force standing between vulnerable troop transport and supply ships engaged in landings on the Philippine island of Leyte and a powerful Japanese surface fleet of battleships and cruisers. In desperation, lightly armed Avengers and FM-2 Wildcats from Taffys 1, 2 and 3 resorted to tactics such as strafing ships, including the bridge of the Japanese battleship Yamato, while the destroyers and destroyer escorts charged the enemy. Confused by the fierce resistance, the Japanese fleet eventually withdrew from the battle.
Four U.S. Marine Corps Wildcats played a prominent role in the defence of Wake Island in December 1941. USN and USMC aircraft formed the fleet's primary air defense during the Battles of Coral Sea and Midway, and land-based Wildcats played a major role during the Guadalcanal Campaign of 1942–43. It was not until 1943 that more advanced naval fighters capable of taking on the Zero on more even terms, the Grumman F6F Hellcat and Vought F4U Corsair, reached the South Pacific theatre.
7,860 Wildcats were built. During the course of the war, Navy and Marine F4Fs and FMs flew 15,553 combat sorties (14,027 of these from aircraft carriers, destroying 1,327 enemy aircraft at a cost of 178 aerial losses, 24 to ground/shipboard fire, and 49 to operational causes (an overall kill-to-loss ratio of 6.9:1). True to their escort fighter role, Wildcats dropped only 154 tons of bombs during the war.
This little fighter here in Aces High is a highly respected opponent in aerial combat, as in the hands of a capable pilot, this thing is hard to kill!
