The Hellcat and the Vought F4U Corsair were the primary United States Navy carrier fighters in the second half of World War II. The Hellcat was withdrawn from service shortly after the war's end. The Hellcat was also used by the Royal Navy's Fleet Air Arm where it was initially known as the "Gannet" however this name was later discontinued and the Hellcat name used instead. Development Originally to be given the Wright R-2600 Cyclone engine of 1,700 hp (1,268 kW), the Hellcat was given the Pratt & Whitney R-2800 Double Wasp 2,000 hp (1,500 kW) after British combat experience with the Wildcat indicated better performance was necessary. The first, Cyclone-equipped prototype flew on June 26 1942, and the first Double Wasp-equipped aircraft on July 30, 1942. The first production aircraft off the line flew on 3 October 1942; the type reached operational readiness with VF-9 on USS Essex in March 1943. Construction Like the Wildcat, the Hellcat was a tough, straightforward aircraft, designed to be easy to manufacture and able to take severe damage and return safely to the carrier. 212 lb (96 kg) of cockpit armor was fitted to aid survival, as well as a bullet-proof windshield and armor around the engine oil tank and oil cooler. The family resemblance to the earlier aircraft was strong, but the Hellcat wasn't just a bigger, heavier, faster Wildcat. Instead of the Wildcat's narrow-track undercarriage retracting into the fuselage by hand, the Hellcat had hydraulically-actuated undercarriage legs set wider and retracting backward into the wings. The wing was low-mounted instead of mid-mounted. Armament consisted of the same six 0.5 in (12.7 mm) Browning machineguns as later Grumman-built Wildcats; later aircraft gained three hardpoints to carry 1,000 lb (450 kg) bombs. Action The Hellcat first saw action against the Japanese on 1 September 1943 when fighters off the USS Independence (CVL-22) shot down a snooping seaplane. Soon after, on 23 November, Hellcats engaged Japanese aircraft over Tarawa shooting down a claimed 30 Mitsubishi Zeros for the loss of one F6F. Hellcats were involved in practically all engagements with Japanese air power from that point onward. They were the major type of USN fighter involved in the Battle of the Philippine Sea where so many Japanese aircraft were shot down that the USN aircrews nicknamed the battle The Great Marianas Turkey Shoot.
