Hellcat production was all the more remarkable considering that many of the Grumman employees had never built airplanes before. The Wildcat's intended replacement, the Vought F4U Corsair (see NASM collection), first flown in 1940, was showing great promise, but development was slowed by problems, including the crash of the prototype. Manufacturers. Still, the quality of the Long Island-produced airplanes was such that in 1942 Vice Admiral John S. McCain Sr. (grandfather of U.S. "Naval Aviation Combat Statistics World War II, OPNAV-P-23V No. In fact, more Wildcats were built by Eastern than by Grumman. Green, William and Gordon Swanborough. A float-equipped version, known as the Wildcatfish, was tested, but the rapid expansion of land bases and of the escort carrier fleet ended the need for an amphibious airplane. This practice would make the F6F a tough, uncomplicated, easy-to-manufacture aircraft. Instrumentation on board and photographic plates taped to the control stick obtained data on radioactivity. F8F-1 Specs While not a combat veteran like her sisters, this Wildcat has survived to tell the story of the GM Eastern plants in New Jersey, the Escort Carriers, Island Hopping in the Pacific balanced with long summer days in the Midwest and on the coast, flying rides, airshows and introducing several generations to flight. The U.S. Navy officially adopted the aircraft type on 1 October 1941 as the Wildcat. [55] These two squadrons were disbanded in 1946. A 250USgal (950L) self-sealing fuel tank was fitted in the fuselage. [19] In addition, the forward fuselage sloped down slightly to the engine cowling, giving the Hellcat's pilot good visibility. US Navy pilots, including John "Jimmy" Thach, a pioneer of fighter tactics to deal with the A6M Zero, were greatly dissatisfied with the Wildcat's inferior performance against the Zero in the battles of the Coral Sea and Midway. U.S. Navy Wildcats participated in Operation Torch. [9][10], Grumman had been working on a successor to the F4F Wildcat since 1938, and the contract for the prototype XF6F-1 was signed on 30 June 1941. From 1943-1945, when the Hellcat was in service, only 42 carrier-based bombers or torpedo planes are known to have been lost to Japanese aircraft. The main differences were additional armor plate, a reinforced empennage, and the addition of the R-2800-10W engine, which had water injection for a limited boost in combat power. Oxford, UK: Osprey Publishing, 2013. The Grumman F6F Hellcat is an American carrier-based fighter aircraft of World War II. Length: 27 ft. 6 in. [41] In October 1942, long-ranged and unarmed F4F-7s began replacing the F4F-3Ps, but a detachment of three F4F-3P from VMO-155 operated from the Bogue-class escort carrier USS Nassau (CVE-16) during the amphibious invasion of Attu Island in May 1943. (Britains Royal Navy also flew the fighter, dubbing it the Martlet.). [24], From 1943, 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. Records indicate that exposure of this aircraft to the radioactive cloud was minimal and residual radiation is negligible. F7F-3 Specs [12][20] In addition, the rear fuselage and tail units were strengthened, and apart from some early production aircraft, most of the F6F-5s built were painted in an overall gloss sea-blue finish. [30], Thach was greatly dissatisfied and a vocal critic of the Wildcat's performance during the war (as were many US carrier pilots), stating in his Midway action report;[5]. This is perhaps one of the most interesting Wildcat survivors (Bu #86680). [31] At first, GM produced the FM-1, identical to the F4F-4, but reduced the number of guns to four, and added wing racks for two 250lb (110kg) bombs or six rockets. Poor design of the armament installation on early F4Fs caused these otherwise reliable machine guns to frequently jam, a problem common to wing-mounted weapons of many U.S. fighters early in the war. Grumman built the heavily armored Hellcat based on the F4F design but with different landing gear, much larger wings, and a bigger engine and propelleressentially a brand-new fighter. Span: 42 ft. 10 in. This page was last edited on 22 February 2023, at 19:17. [17] This was the first combat victory by a US-built fighter in British service in World War II.[17]. [54] After attempts to fit British radio sets, it was decided to use the superior American equipment. The advanced Wildcat had turned, by a process of evolution, into the Hellcat. Max Speed: 450 mph During these battles, it became clear that attacks without fighter escort amounted to suicide, but that the fighter component on the carriers was completely insufficient to provide both fighter cover for the carrier and an escort for an attack force. Length: 33 ft. 7 in. [59] The French Air Force also used the Hellcat in Indochina from 1950 to 1952. This original fighter was the Hawker "Typhoon" - a machine that having high flight data could not compete with the German aircraft in any struggles at high altitude: a thick . The U.S. Navy much preferred the more docile flight qualities of the F6F compared with the Vought F4U Corsair, despite the superior speed of the Corsair. So parts and assemblies were shared from Grumman lines to Eastern and back during the war assuring continuity when snags arose. Max Speed: 434 mph "Grumman F6F Hellcat". Hellcat Wildcat Some of the older aircraft encyclopedias describe the Hellcat as a "big beefy fighter" as opposed to the lighter, older and less powerful Wildcat. Instrumentation on board and photographic plates taped to the control stick obtained data on radioactivity. Designed to replace the earlier F4F Wildcat and to counter the Japanese Mitsubishi A6M Zero, it was the United States Navy's dominant fighter in the second half of the Pacific War. (National Archives) It was the largest number of fighter aircraft ever produced at a single facility, and it almost didn't happen. [25] The later F6F-3N, first flown in July 1943, was fitted with the AN/APS-6 radar in the fuselage, with the antenna dish in a bulbous fairing mounted on the leading edge of the outer right wing as a development of the AN/APS-4; about 200 F6F-3Ns were built. Even so, the aircraft performed well against the best Japanese opponents with a claimed 13:1 kill ratio against the A6M Zero, 9.5:1 against the Nakajima Ki-84, and 3.7:1 against the Mitsubishi J2M during the last year of the war. [citation needed][60]. The FM-2 covered the Philippine campaign with distinction. In British service initially, the aircraft were known as the Martlet I, but not all Martlets would be to exactly the same specifications as U.S. Navy aircraft. In 1943, the game changed when the American F6F Hellcat entered the war. For some strange reason, even after I had poured about five or six hundred rounds of ammunition directly into the Grumman, the airplane did not fall, but kept on flying. Initially designed as a twin-engine carrier-based fighter, the Tigercat revealed a problem maintaining directional stability when it was first flown on November 3, 1943. The British directly ordered and received a version with the original Twin Wasp, but again with a modified cowling, under the manufacturer designation G-36B. A bigger powerplant, however, would require the use of a larger propeller, which in turn necessitated a taller landing gear for increased ground clearance.

"One Thousand Planes a Day: Ford, Grumman, General Motors and the Arsenal of Democracy.". Length: 28 ft. 11 in. USN escort carriers in the Atlantic used Wildcats until the end of the war. Clearly the most pressing need in the Wildcat was a larger engine to boost performance. Production later switched to the improved FM-2 (based on Grumman's XF4F-8 prototype, informally known as the "Wilder Wildcat") optimized for small-carrier operations, with a more powerful engine and a taller tail to cope with the increased torque. Grumman didnt get a production order, and one wonders if the F5F might have succeeded had it too sported a cat name. Before the Fleet Air Arm took on charge the Martlet Mk Is, it had already ordered 100 G-36B fighters. [11] Instead of the Wildcat's narrow-track, hand-cranked, main landing gear retracting into the fuselage inherited from the F3F ( a design from the 1930s Grumman FF-1 fighter biplane), the Hellcat had wide-set, hydraulically actuated landing-gear struts that rotated through 90 while retracting backwards into the wings, but with full wheel doors fitted to the struts that covered the entire strut and the upper half of the main wheel when retracted, and twisted with the main gear struts through 90 during retraction. The first shipboard operations of the type in British service were in September 1941, aboard HMSAudacity, a very small escort carrier with a carrier deck of 420ft (130m) by 59ft (18m), no elevators and no hangar deck. By then, Grumman had produced 4,403 F6F-3s, which included 150 F6F-3N and F6F-3E night fighters, and a number of F6F-3P . Advertising Notice Thach. The Grumman Hellcat was a newer, improved fighter aircraft than the Grumman Wildcat, being 5 years newer design, and able to integrate wartime experience. The aircraft had become more important than ever with the continued delay of the Corsair. Armstrong managed to fly to a base, so he could eject over friendly territory. The Navy desperately needed the increased performance of the Hellcat to combat the Zero's dominance. The wing-sweep mechanism would be fine, however, and in later years the knowledge gained from the Jaguar was applied to the F-111 Aardvark and F-14 Tomcat. This design was still not competitive with the Brewster F2A Buffalo which won initial U.S. Navy orders, but when the F4F-3 development was fitted with a more powerful version of the engine, a Pratt & Whitney Twin Wasp R-1830-76, featuring a two-stage supercharger, it showed its true potential.[35].
