2 September 1937: First flight, Grumman XF4F-2 Bu. No.¹ 0383, a prototype fighter for the United States Navy and Marine Corps. The airplane was designed by Grumman’s Chief Engineer, Robert Leicester Hall.
The prototype was damaged when it nosed over during a forced landing, 11 April 1938. The pilot, Lieutenant Gurney, was not injured. 0383 was rebuilt as an XF4F-3. The Navy ordered the fighter into production as the F4F-3 Wildcat. XF4F-3 0383 was destroyed in an accident, 16 December 1940. The pilot was killed.
The Grumman F4F-3 Wildcat was a single-engine, single-place, mid-wing monoplane fighter designed for operation from aircraft carriers. F4F-4 and later variants had folding wings for a smaller “foot print” while stored aboard.
The F4F-3 Wildcat was 28 feet, 10½ inches (8.801 meters) long with a wingspan of 38 feet, 0 inches (11.582 meters). The height over the propeller with the airplane in 3-point attitude was 11 feet, 9 inches (3.581 meters). The wings had a total area of 260 square feet (24.16 square meters). They had 0° incidence and no leading edge sweep. Thewings had 5° dihedral. The F4F-3 had an empty weight of 5,293 pounds (2,401 kilograms) and gross weight of 7,432 pounds (3,371 kilograms) with 147 gallons (556 liters) of gasoline.
The F4F-3 was powered by an air-cooled, supercharged, 1,829.39-cubic-inch-displacement (29.978 liter) Pratt & Whitney Twin Wasp SSC7-G (R-1830-86) two-row, 14-cylinder radial engine with a compression ratio of 6.7:1. The R-1830-86 had a normal power rating of 1,100 at 2,550 r.p.m., from Sea Level to 3,300 feet (1,006 meters), and 1,000 horsepower at 2,550 r.p.m. at 19,000 feet (5,791 meters). It was rated at 1,200 horsepower at 2,700 r.p.m. for takeoff. The engine turned a three-bladed Curtiss Electric propeller with a diameter of 9 feet, 9 inches (2.972 meters) through a 3:2 gear reduction. The R-1830-86 was 4 feet, 0.19 inches (1.224 meters) in diameter, 5 feet, 7.44 inches (1.713 meters) long, and weighed 1,560 pounds (708 kilograms).
The F4F-3 had a maximum speed of 278 miles per hour (447 kilometers per hour) at Sea Level, and 330 miles per hour (531 kilometers per hour at 19,000 feet (5,791 meters). It could climn to 20,000 feet (6,096 meters) in 7.6 minutes. The service ceiling was 30,500 feet (9,296 meters) and its maximum range was 1,280 miles (2,060 kilometers).
The F4F-3 Wildcat was armed with four Browning AN-M2 .50-caliber machine guns. Later variants would have six guns.
The F4F Wildcat was produced by Grumman and the General Motors Corporation Eastern Aircraft Division as the FM-1. Grumman shifted to production of teh F6F Hellcat in early 1943. GM continued to build Wildcats until the end of the War. A total of 7,885 were built.

21 November 1947: Grumman Aircraft Engineering Corporation engineering test pilot Corwin Henry (“Corky”) Meyer took off from the company’s airfield at Bethpage, Long Island, New York, in the first prototype XF9F-2 Panther, Bu. No. 122475. After the preliminary flight evaluation, Meyer landed the new jet fighter on a longer runway at Idlewild Airport. The Bethpage runway was only 5,000 feet (1,524 meters) long. As the first jet aircraft built by Grumman, it wasn’t known if the XF9F-2 could land on that short a runway.
Air & Space/Smithsonian magazine quoted Meyer as saying that the weather was “the foulest of any first flight in my experience.” He described the prototype’s handling qualities: “It handled like a J-3 Cub.” In an article for Flight Journal, Corky Meyer wrote: “I conducted a very satisfactory first flight of the 5,000-pound-thrust Rolls-Royce Nene-powered fighter on November 21, 1947.”
The XF9F-2 Panther was the first jet-powered aircraft to be built by Grumman, a major supplier of aircraft for the United States Navy. It was a single-seat, single-engine, day fighter, designed for operation on the U.S. Navy’s aircraft carriers. It was developed from a proposed four-engine XF9F-1 night fighter. Grumman planned to use the Rolls-Royce RB.41 Nene centrifugal-flow turbojet engine. With 5,000 pounds rated thrust at 12,400 r.p.m., the Nene was more powerful (and more reliable) than any engine manufactured by an American company.
Originally it was planned that the Nene would be licensed for production to the Taylor Turbine Corporation as the J42-TT-2. No J42s were ready, so Taylor supplied Grumman with imported Rolls-Royce engines. The Navy had concerns about Taylor’s capability to produce engine in sufficient quantities and arranged for the J42 license to be sold to Pratt & Whitney.
The Panther was placed into production as the F9F-2. The F9F-2 was 37 feet, 5-3/8 inches (11.414 meters) long with a wingspan of 38 feet, 5⅜ inches (11.719 meters) long, with a wingspan of 38 feet, 0 inches (11.528 meters)—not including wing tanks. Its overall height was 11 feet, 4 inches (3.454 meters). The wings could be hydraulically folded to reduce the span for storage aboard ship. The Panther weighed 9,303 pounds (4,220 kilograms) empty, and had a gross weight of 19,494 pounds (8,842 kilograms.
The F9F-2 was powered by a Pratt & Whitney JT6 (J42-P-8) turbojet engine which produced 5,000 pounds of thrust (22.241 kilonewtons) at Sea Level, and 5,750 pounds (25.577 kilonewtons) with afterburner. The J42 was a license-built version of the Rolls-Royce Nene. The engine used a single-stage centrifugal-flow compressor, 9 combustion chambers and a single-stage axial-flow turbine. The J42-P-8 weighed 1,715 pounds (778 kilograms).
The Panther had a maximum speed of 575 miles per hour (925 kilometers per hour) at Sea Level. Its service ceiling was 44,600 feet (13,594 meters), and the range was 1,353 miles (2,177 kilometers).
The Panther was armed with four M3 20 mm autocannon placed in the nose with 760 rounds of ammunition. It could carry up to 3,000 pounds (1,361 kilograms) of bombs or eight 5-inch (12.7 centimeters) rockets on four hardpoints under each wing.
It was a very successful air-to-air and air-to-ground fighter during the Korean War. On 18 November 1952, Lieutenant Elmer Royce Williams, USN, flying an F9F-5 Panther, Bu. No. 125459, of VF-781 aboard the aircraft carrier USS Oriskany (CVA-34), shot down four of seven Soviet Air Force MiG 15 fighters which had launched from Vladivostok toward Task Force 77. His Panther sustained significant damage from enemy cannon shells. Though he safely returned to his carrier, the fighter, Number 106, was so badly damaged that it was pushed over the side. Lieutenant Royce was awarded the Silver Star for this action. No other pilot has ever shot down four MiG fighters during a single combat action.
The F9F Panther was flown during the Korean War by such famed naval aviators as Ted Williams, and future astronauts John Glenn and Neil Armstrong.
Grumman built 1,358 F9F-2,-3,-4 and -5 Panthers and another 1,392 swept wing F9F-6, -7 and -8 Cougars. Panthers remained in service with the United States Navy until 1958, and Cougars until 1974.
Corwin Henry (“Corky”) Meyer ¹ was born 14 April 1920 at Springfield, Illinois. He was the second of three children of Dr. John Gerhard Meyer, a physician and surgeon, and Betsy Arenia Corwin Meyer.
At the age of 17 years, Corky Meyer learned to fly in the Civilian Pilot Training Program. (This was a federal government-funded program which provided 72 hours of ground school and 35–50 hours of flight training, intended to increase the number of pilots available for civilian aviation.)
Meyer attended Springfield High School, in Springfield. He was a member of the Senior Boys’ Council and the National Honor Society. Meyer graduated from high school in May 1938, then entered the University of Illinois. He studied at the at the Massachusetts Institute of Technology (M.I.T.), Cambridge, Massachusetts, 1942–43.
Meyer was a pilot trainee for Pan American Airways before being employed as an engineering test pilot at the Grumman Aircraft Engineering Corporation at Bethpage, New York.
Meyer’s first project was testing newly-built TBF Avenger torpedo bombers. Later he was was a project test pilot for the F6F Hellcat, F8F Bearcat and F7F Tigercat. (Robert Leicester Hall made the first flights of these airplanes, but Corky Meyer was involved in flight testing of each of them early on.)
Corwin H. Meyer married Miss Dorothy Marjorie Fyfield, 7 April 1945, at Huntington, New York. They would have a daughter, Sandra Louise Meyer, born in 1950, and two sons, John Fyfield Meyer and Peter Meyer.
On 19 May 1952, Corky Meyer took the prototype variable-wing-sweep XF10F-1 Jaguar for its first flight at Edwards Air Force Base, California.
From 1952 to 1954, Meyer was head of Grumman’s flight operations at Edwards Air Force Base in California. In 1954, he became the first civilian airplane pilot to qualify for flight operations aboard U.S. Navy aircraft carriers, when he flew an F9F-6 Cougar to USS Lake Champlain (CVA-39). ²
Corky Meyer made the first flight of the XF9F-9 prototype, Bu. No. 138604, on 30 July 1954, and was able to approach mach 1 in level flight. The XF9F-9 was a completely redesigned F9F Cougar, which incorporated the “wasp-waist” in its area-ruled fuselage. The following year, this type would be redesignated the F11F Tiger.
In 1967, Meyer was appointed vice president of Grumman, and in 1968, he was elected to the board of directors of the Grumman Aerospace Corporation. He became the senior vice president of Grumman Aerospace in 1972. In 1974, Meyer became President of Grumman American Aviation Corp., Savannah, Georgia, a subsidiary which produced light civil airplanes, the Grumman AgCat, and the Gulfstream line of executive jets. Corwin Meyer retired from Grumman in 1978. He later served as chief executive officer of the Enstrom Helicopter Corporation and the Falcon Jet Corporation.
Meyer was an early member of the Society of Experimental Test Pilots. In 1971, he was awarded SETP’s James H Doolittle Award for excellence in technical management or engineering achievement in aerospace technology. In 1999 the National Aeronautic Association selected him for its Elder Statesman Award.
Meyer was the author of Corky Meyer’s Flight Journal, an autobiography published in 2005, by Specialty Press, North Branch, Minnesota.
Corwin Henry Meyer died in Naples, Florida, 1 June 2011, at the age of 91 years.
¹ Lutheran Church birth and baptismal records give Meyer’s name as “Henry Corwin Meyer.”
² On 3 April 1991, TDiA’s author became the only civilian helicopter pilot (at that time, and who was not a former military pilot) to qualify to fly from U.S. Navy warships at sea. The Deck Landing Qualification (DLQ) flights were evaluated by instructors from Helicopter Antisubmarine (Light) Squadron (HSL-31) aboard USS Kincaide (DDG-965), a Spruance-class guided missile destroyer.
