[34] True to their escort fighter role, Wildcats dropped only 154 tons of bombs during the war. [31] The F6F-5 was the most common F6F variant, with 7,870 being built. Index. [9][10], It was clear to Grumman that the XF4F-1 would be inferior to the Brewster monoplane, so Grumman abandoned the XF4F-1, designing instead a new monoplane fighter, the XF4F-2. These machines were named Martlet Mk IV. The Hellcat was a major improvement on the Wildcat, with a 2 row, 18 cylinder P&W R-2800 engine. [44], The U.S. Navy's all-time leading ace, Captain David McCampbell, scored all his 34victories in the Hellcat. The Fleet Air Arm purchased 312 FM-1s, originally with the designation of Martlet V. In January 1944, a decision was made to retain the American names for US-supplied aircraft, redesignating the batch as the Wildcat V. The Wildcat VI was the Air Ministry name for the FM-2 Wildcat in FAA service. Phone: (978) 562-9182 [55] These two squadrons were disbanded in 1946. [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. Manufacturers. By the time Hellcat production was in full swing, the lessons learned at Easterns Wildcat production in New Jersey enabled Grumman to build 400 Hellcats a month. They would see post-war service in a limited role in the U.S. Navy until 1953, and also in the French and Uruguayan navies. Designed as a "Zero Killer," the F6F maintained a kill ratio of . Instrumentation on board and photographic plates taped to the control stick obtained data on radioactivity. During the May 4 to 8, 1942 clash off the Solomons, U.S. Navy Wildcats shot down 14 A6Ms for a loss of just 10 aircraft. Height: 9 ft. 11 in. Only one was converted. At the time of Pearl Harbor, only Enterprise had a fully equipped Wildcat squadron, VF-6 with F4F-3As. Nevertheless, the first 10 received had fixed wings. [11] After losing out to Brewster, Grumman completely rebuilt the prototype as the XF4F-3 with new wings and tail and a supercharged version of the Pratt & Whitney R-1830 "Twin Wasp" radial engine. 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. The F6F Hellcat still bore a family resemblance, however, to its predecessor and there was little that was revolutionary in its design. Building on the F4F F4F Wildcat. At the same time a Hamiliton Standard Hydromatic propeller replaced the Curtiss propeller. [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. Span: 42 ft. 10 in. 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. [43], U.S. Navy and Marine F6F pilots flew 66,530 combat sorties and claimed 5,163 kills (56% of all U.S. Navy/Marine air victories of the war) at a recorded cost of 270 Hellcats in aerial combat (an overall kill-to-loss ratio of 19:1 based on claimed kills).

Max Speed: 450 mph [54], FAA Hellcats, as with other Lend-Lease aircraft, were rapidly replaced by British aircraft after the end of the war, with only two of the 12 squadrons equipped with the Hellcat at VJ-Day still retaining Hellcats by the end of 1945. Grumman built a total of 12,275 F6F Hellcat, of which 11,000 were built in just two years. [20] .mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}. The Grumman F6F Hellcat was originally conceived as an advanced version of the U.S. Navy's then current front-line fighter, the F4F Wildcat (see NASM collection). [13], The overall performance of Grumman's new monoplane was felt to be inferior to that of the Brewster Buffalo. 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. [60], The Uruguayan Navy also used them until the early 1960s. *The Wildcat is currently on display inside the American Heritage Museum next to our Pacific Theater exhibit. These aircraft were given the designation Martlet II by the British. The FM-1 Wildcat evolved with Eastern and Grumman collaborating on the new FM-2 design, which was required by the USN for its Jeep or Escort Carriers. Not until late in the war would Japanese aircraft such as the Kawanishi N1K George (see NASM collection) challenge the Hellcat. [citation needed][60]. It had a nine cylinder radial engine, and a narrow track landing gear. The increase to six guns was attributed to the Royal Navy, who wanted greater firepower to deal with German and Italian foes. In a departure from the militarys usual practice, the F9F designation was retained even after the aircraft was transformed into the Cougar: In 1951, the Panthers straight wing was replaced with a wing swept back 35 degrees. When attacking, use your superior power and high-speed performance to engage at the most favorable moment. Navy F4F-3s were replaced by F4F-4s in June 1942. The advanced Wildcat had turned, by a process of evolution, into the Hellcat. Just under nine lives that created a company legend. The Spitfire was the more manoeuvrable of the two in a turning fight, the Hellcat was stronger and faster and could stay in th. [55], After the war, the Hellcat was succeeded by the F8F Bearcat, which was smaller, more powerful (powered by uprated Double Wasp radials) and more maneuverable, but entered service too late to see combat in World War II. It was required that aircraft components manufacuted at both plants be interchangable. On arrival, it was assigned to VF-3 where it sustained damage in a wheels-up landing at NAS Barbers Point, Hawaii. Pilot Aviation Alphabet. The bombings of Hiroshima and Nagasaki changed everything, and the portly but deadly dogfighting Wildcat was now without a fight. Late in the war, the Wildcat was obsolescent as a front-line fighter compared to the faster (380 mph/610 km/h) F6F Hellcat or much faster (446 mph/718 km/h) F4U Corsair. Grumman's Wildcat production ceased in early 1943 to make way for the newer F6F Hellcat but General Motors continued producing Wildcats for U.S. Navy and Fleet Air Arm use. The Wildcat continued to be built throughout the remainder of the war to serve on escort carriers, where the larger and much heavier Hellcat could not be used. Because of Grumman's foresight in starting production early, Hellcats began rolling off the assembly line immediately and construction continued at an ever-increasing rate. At first, GM produced the FM-1 (identical to the F4F-4 but with four guns). The Grumman F6F Hellcat is an American carrier-based fighter aircraft of World War II. Grumman didnt get a production order, and one wonders if the F5F might have succeeded had it too sported a cat name. 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. featuring the Jacques M. Littlefield Collection explores major conflicts [3][4][5] The Wildcat has a claimed air combat kill-to-loss ratio of 5.9:1 in 1942 and 6.9:1 for the entire war.[6]. A few standard F6F-5s were also fitted with camera equipment for reconnaissance duties as the F6F-5P. It could carry rockets as well as bombs. Known components were used, and ease of manufacture was always a priority. After the war, civilian users added belly tanks to operate Tigercats as firebombers. "Corpulent Feline: Grumman's F4F Wildcat: Part One". [22] [Note 5], The F6F series was designed to take damage and get the pilot safely back to base. 6 x 5-inch (127mm) HVAR unguided rockets underwing. A variant of the F4F-4, designated F4F-4B for contractual purposes, was supplied to the British with a modified cowling and Wright Cyclone engine. [13], Throughout early 1942, Leroy Grumman, along with his chief designers Jake Swirbul and Bill Schwendler, worked closely with the U.S. Navy's Bureau of Aeronautics (BuAer) and experienced F4F pilots,[14] to develop the new fighter in such a way that it could counter the Zero's strengths and help gain air dominance in the Pacific Theater of Operations. It was inspired by appearance of the A6M2-N "Rufe", a modification of the Mitsubishi A6M2 "Zeke". Like the Hellcat, the R-2800 was rugged and easily maintained. 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. Enter the Grumman F6F Hellcat. [27] In total, 4,402 F6F-3s were built through until April 1944, when production was changed to the F6F-5. Green, Swanborough and Brown 1977, pp. [40] Soon after, on 23 and 24 November, Hellcats engaged Japanese aircraft over Tarawa, shooting down a claimed 30 Mitsubishi Zeros for the loss of one F6F. [citation needed], In June 1942, 17 F4F-3s and one F4F-3A (18 total) were converted into F4F-3P photoreconnaissance planes. Ten fixed-wing G-36Bs were used by the FAA as Martlet III(A). The Hellcat was developed as an improvement upon a previous Grumman plane, the F4F Wildcat. Grumman FM-2 Wildcat Single-Seat, Single-Engine Carrierborne Monoplane Fighter Aircraft. they are:[63], Data from WWII Aircraft Performance[95]Janes Fighting Aircraft of World War II[96]Standard Aircraft Characteristics[97], Aircraft of comparable role, configuration, and era. Height: 12 ft. 4 in. [15] On 22 April 1942, Lieutenant Commander Butch O'Hare toured the Grumman Aircraft company and spoke with Grumman engineers, analyzing the performance of the F4F Wildcat against the Mitsubishi A6M Zero in aerial combat. [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]. [23][N 3] During the course of the war, Navy and Marine F4Fs and FMs flew 15,553 combat sorties (14,027 of these from aircraft carriers[32]), destroying a claimed figure of 1,327 enemy aircraft at a cost of 178 aerial losses, 24 to ground/shipboard fire, and 49 to operational causes[33] (an overall claimed kill-to-loss ratio of 6.9:1). ALTERNATIVE (F6F-5N): 2 x 20mm cannons WITH 4 x .50 caliber machine guns.2 x 11.75 (298mm) "Tiny Tim" unguided rockets underwing. He was awarded a DFC, and a Gold Star in lieu of a second DFC. The Hellcat remained the standard USN carrier-borne fighter until the F4U series was finally cleared for U.S. carrier operations in late 1944 (the carrier landing issues had by now been tackled largely due to use of Corsair by the Royal Navy Fleet Air Arm, which started in 1943). The type also pioneered combat operations from the smaller escort carriers. Both aircraft had great strengths and weaknesses. After repair, it was assigned to VF-83 where it was used in a training role until February 21, 1945. USN escort carriers in the Atlantic used Wildcats until the end of the war. Any success our fighter pilots may have had against the Japanese Zero fighter is not due to the performance of the airplane we fly but is the result of the comparatively poor marksmanship of the Japanese, stupid mistakes made by a few of their pilots and superior marksmanship and team work of some of our pilots. Span: 35 ft. 6 in. It performed well, was easy to fly, and was a stable gun platform, but what I really remember most was that it was rugged and easy to maintain. [34], The original Grumman F4F-1 design was a biplane, which proved inferior to rival designs, necessitating a complete redesign as a monoplane named the F4F-2. A center-section hardpoint under the fuselage could carry a single 150USgal (570L) disposable drop tank, while later aircraft had single bomb racks installed under each wing, inboard of the undercarriage bays; with these and the center-section hard point, late-model F6F-3s could carry a total bomb load in excess of 2,000lb (910kg). "Grumman F6F Hellcat". In any case, the construction of the airfields at forward bases by the "Seabees" was surprisingly quick. Only one XF10F was completed: It and the nearly complete second airframe ignominiously ended their days as arresting-barrier test airframes. As the performance of the basic F4F-3 was already below that of the Zero, the F4F-3S was clearly of limited usefulness. The plane equipped four squadrons (including the Normandie-Niemen squadron of WWII fame) before these units transitioned to the F8F Bearcat. During the Battle of Midway, only VMF-221 still used F4F-3s. When trials were flown against a captured A6M5 model Zero, they showed that the Hellcat was faster at all altitudes. U.S. Navy orders followed as did some (with Wright Cyclone engines) from France; these ended up with the Royal Navy's Fleet Air Arm after the fall of France and entered service on 8 September 1940. It was the single-engined Grumman F4F Wildcat, a carrier-based fighter first made in 1937. Belgium surrendered before any aircraft were delivered and by 10 May 1940, the aircraft order was transferred to the Royal Navy. Grumman FM-2 Wildcat Designed and ordered in 1936, the Wildcat finally entered service in November 1940. Although records show it to be a successful fighter, during World War II it was outclassed in several areas. Larger fighters such as the Hellcat and the Corsair and dive bombers were needed aboard fleet carriers and the Wildcat's slower landing speed made it more suitable for shorter flight decks.[31]. [44] Claimed victories were often highly exaggerated during the war. Operations from Audacity also demonstrated that the fighter cover was useful against U-boats. It is indeed surprising that any of our pilots returned alive. Although it was a superlative aircraft, the rise of jet fighters ended the Bearcats career as a U.S. fighter almost before it began, and most F8Fs were withdrawn from service before the Korean War. On the next voyage, four Fw 200 Condors fell to the guns of the Martlets, and of the combined total, two of these five Condors were shot down by Eric "Winkle" Brown during his time aboard. The Hellcat dominated aerial combat and is credited with destroying over 5,000 enemy aircraft. Modern Airpowers. 568 Main Street On 20 September, a German Fw 200 was shot down. [26] Hellcat night fighters claimed their first victories in November 1943. [5], Hellcats were credited with destroying a total of 5,223 enemy aircraft while in service with the U.S. Navy, U.S. Marine Corps, and Royal Navy Fleet Air Arm (FAA). Terms of Use [56], The Hellcat was used for second-line USN duties, including training and Naval Reserve squadrons, and a handful were converted to target drones. This preference was especially noted during carrier landings, a critical success requirement for the Navy. A 250USgal (950L) self-sealing fuel tank was fitted in the fuselage. In 1943, the game changed when the American F6F Hellcat entered the war. I turned the 20mm cannon switch to the "off" position, and closed in. Rate of climb was noticeably worse in the F4F-4; while Grumman optimistically claimed the F4F-4 could climb at a modest 1,950ft (590m) per minute, in combat conditions, pilots found their F4F-4s capable of ascending at only 500 to 1,000ft (150 to 300m) per minute.
