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).

24 August 1942: Flying a Grumman F4F Wildcat, Lieutenant Marion Eugene Carl, United States Marine Corps, a 27-year-old fighter pilot assigned to Marine Fighter Squadron 223 (VMF-223) based at Henderson Field, Guadalcanal Island, shot down four enemy airplanes in one day. They were a Mitsubishi A6M “Zeke” fighter, a Mitsubishi G4M1 “Betty” medium bomber and two Nakajima B5N2 “Kate” torpedo bombers. Carl had previously shot down an A6M during the Battle of Midway, less than three months earlier. He now had five aerial combat victories, making him the Marine Corps’ first ace.

Captain Carl was awarded the Navy Cross (his second) for his actions in the Solomon Islands from 24 August to 9 September 1942.

Marion Carl’s fighter was a Grumman F4F-4 Wildcat, designed by Robert Leicester Hall as a carrier-based fighter for the United States Navy. The F4F-4 was a single-place, single-engine, mid-wing monoplane with retractable landing gear.

The F4F-4 was 29 feet, 9-3/8 inches (9.077 meters) long, with a wingspan of 38 feet, 0 inches (11.582 meters) and overall height of 12 feet, 1-3/8 inches (3.693 meters). Unlike the preceding F4F-3, the F4F-4 had folding wings for storage aboard aircraft carriers. With the wings folded, the airplane was 14 feet, 4 inches (4.369 meters) wide. Its empty weight was 5,895 pounds (2,674 kilograms), and the gross weight was 7,975 pounds (3,617 kilograms).

The F4F-4 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-4 had a maximum speed of 284 miles per hour (457 kilometers per hour) at Sea Level, and 320 miles per hour (515 kilometers per hour) at 18,800 feet (5,730 meters). Its service ceiling was 34,000 feet (10,363 meters).

While the F4F-3 Wildcat was armed with four air-cooled Browning AN-M2 .50-caliber machine guns; the F4F-4 had six. It carried 1,400 rounds of ammunition.

The prototype XF4F-1 made its first flight in 1935. It was substantially improved as the XF4F-2. The first production F4F-3 Wildcat was built in February 1940. The airplane remained in production through World War II, with 7,860 built by Grumman and General Motors Eastern Aircraft Division (FM-1 Wildcat).

According to the National Naval Aviation Museum, F4F Wildcats held a 9:1 ratio of victories over Japanese aircraft, with 1,006 enemy airplanes destroyed in combat.

Marion Eugene Carl was born at Hubbard, Oregon, 1 November 1915. He was the second of four children of Herman Lee Carl, a dairy farmer, and Ellen Lavine Ellingsen Carl.

Carl graduated from Oregon State College at Corvallis, Oregon, and was commissioned as a second lieutenant in the United States Army Reserve, 31 May 1938. Lieutenant Carl soon resigned this commission to accept an appointment as an Aviation Cadet, United States Navy. He enlisted as a private, first class, Volunteer Marine Corps Reserve, 17 July 1938, and was designated a student Enlisted Naval Aviation Pilot assigned to the Naval Reserve Aviation Base, Squantum, Massachusetts. He entered flight school as an Aviation Cadet at Naval Air Station Pensacola near Pensacola, Florida, 26 July 1938.

After completing flight training, Carl was commissioned as a Second Lieutenant, United States Marine Corps Reserve, 20 October 1939. He was then assigned to Marine Fighting Squadron One (VMF-1) at Brown Field, Quantico, Virginia.

In 1940, Lieutenant Carl returned to NAS Pensacola as a flight instructor. On 25 February 1941, Second Lieutenant Carl, U.S.M.C.R., was appointed a Second Lieutenant, United States Marine Corps.

Lieutenant Carl was transferred to VMF-221 at San Diego, California, as a fighter pilot. The unit was assigned to the aircraft carrier USS Saratoga (CV-3) for transportation to Marine Corps Air Station Ewa, Oahu, Territory of Hawaii. On 25 December 1941, VMF-221 was deployed to Midway Atoll.

Marion Carl and his squadron fought during the Battle of Midway. Flying a Grumman F4F-3 Wildcat, Bu. No. 1864,¹ on 4 June 1942, he shot down his first enemy airplane, a Mitsubishi A6M Zero fighter, and damaged two others. Lieutenant Carl was awarded the Navy Cross for his actions in that decisive battle.

Marion Carl was next assigned to VMF-223 under the command of Captain John L. Smith. The Marine fighter squadron was the first air unit to arrive at Henderson Field on the island of Guadalcanal in the Solomons, 20 August 1942. This was a critical airfield, originally built by the Japanese military but occupied by Allied forces. On 24 August, Lieutenant Carl became the Marine Corps’ first “ace.”

Carl was shot down in 9 September 1942 and was missing for five days. He was helped by islanders who eventually returned him to his base.

The squadron departed Guadalcanal 16 October 1942, and sailed to San Francisco, California. VMF-223 was credited with destroying 110½ enemy aircraft. Carl was credited with 16.

Lieutenant Carl married Miss Edna T. Kirvin at New York City, New York, 7 January 1943.

On 26 January, he took command of VMF-223. On 8 May 1943, Lieutenant Carl was promoted to the temporary rank of captain. The squadron was re-equipped with the new Vought-Sikorsky F4U-1 Corsair. Training in the new fighter took place at MCAS El Toro, in southern California.

In August, the squadron returned to combat in the Solomons. By the end of 1943, Major Carl’s total of enemy aircraft destroyed was 18½ with 3 damaged, making him the seventh highest-scoring Marine fighter pilot of World War II.

After the War Marion Carl was assigned as a test pilot at NAS Patuxent River, Maryland, testing jet aircraft on aircraft carriers. He was also the first Marine Corps pilot to fly a helicopter. Carl commanded the Marine’s first jet squadron, VMF-122, which flew the McDonnell FH-1 Phantom. He was promoted to lieutenant colonel 7 August 1947.

In May 1955, Colonel Carl commanded Marine Photo Reconnaissance Squadron One (VMJ-1). The squadron flew the McDonnell FH-2 Banshee from air bases on the island of Formosa (Taiwan) on secret missions over the People’s Republic of China.

At Muroc Army Air Field (now Edwards Air Force Base) Marion Carl tested the Douglas D-558-I Skystreak and D-558-II Skyrocket, setting world records for speed and altitude. He was promoted to colonel, 1 October 1956.

Carl was promoted to major general in August 1967, with his date of rank retroactive to 1 June 1964. Carl commanded the 2nd Marine Aircraft Wing, then served as Inspector General of the Marine Corps from 1970 until 1973. When he retired in 1973, General Carl had accumulated more that 13,000 flight hours.

During his military career, Major General Carl was awarded the Navy Cross with two gold stars (three awards); The Legion of Merit with valor device and three gold stars (four awards); The Distinguished Flying Cross with four gold stars (five awards); and the Air Medal with two gold and two silver stars (twelve awards).

Tragically, General Carl was murdered in Roseburg, Oregon, 28 June 1998, as he defended his wife, Edna, during a home-invasion robbery. Mrs. Carl was wounded, but survived.

Major General Marion E. Carl, United States Marine Corps, is buried at Arlington National Cemetery.

21 August 1989: Forty-five years to the day after the first flight of the prototype Grumman XF8F-1 Bearcat, Lyle Shelton flew his highly-modified Unlimited Class racing plane, the F8F-2 Rare Bear, N777L, over a 3 kilometer course at Las Vegas, New Mexico, setting a Fédération Aéronautique Internationale (FAI) World Speed Record of  850.24 kilometers per hour (528.315 miles per hour),¹ and becoming the world’s fastest piston engine airplane.

Rare Bear had been built for the U.S. Navy at Grumman’s Bethpage, New York, plant, and assigned Bureau of Aeronautics serial number (Bu. No.) 122629. It was a light-weight, high performance interceptor designed to operate from the Navy’s smaller aircraft carriers.

Among other things, the original 2,250 horsepower Pratt & Whitney Double Wasp E12 (R-2800-30W) engine was replaced with a 3,347.66-cubic-inch-displacement (54.858 liter) hybrid Wright R-3350 Duplex-Cyclone 18-cylinder radial engine and a 13 foot, 6 inch (4.115 meters) diameter Aero Products four-bladed propeller from a Douglas AD-Skyraider, with the cowling from a Douglas DC-7. This customized engine reportedly produced 4,500 horsepower at 3,200 r.p.m, with 80 inches of manifold pressure.

Rare Bear won the National Air Races six times and set several speed and time to altitude records.

21 August 1944:¹ The first of two Grumman XF8F-1 Bearcat prototypes, Bu. No. 90460, made its first flight at Bethpage, New York, with Grumman’s Chief Engineer and test pilot Robert Leicester Hall at the controls. The Bearcat was a light-weight high performance interceptor, designed to operate from the U.S. Navy’s smaller aircraft carriers. It used an air-cooled, supercharged, 2,804.4-cubic-inch-displacement (45.956 liter) Pratt & Whitney Double Wasp 2SC13-G (R-2800-22) two-row, 18-cylinder radial engine, an uprated version of the engine used in its predecessor, the Grumman F6F Hellcat.

The R-2800-22 engine was rated at 1,700 horsepower at 2,600 r.p.m. at Sea Level, and 2,100 horsepower at 2,800 r.p.m., for takeoff and Military Power. In order to use the engine’s power more effectively, the prototype Bearcat used a 12-foot, 4-inch (3.759 meter) diameter, four-bladed Aero Products, Inc., propeller, driven through a 0.45:1 gear reduction.

The Bearcat was 20% lighter than the Hellcat. It was 50 miles per hour faster and had a much higher rate of climb.

For aircraft carrier operations, the new fighter could not sacrifice structural strength. In order to limit the weight, armament was reduced to four .50-caliber machine guns, and fuel capacity was also less than that of the Hellcat, giving it reduced range.

The production F8F-1 Bearcat was 27 feet, 6 inches (8.382 meters) long with a wingspan of 35 feet, 6 inches (10.820 meters) and overall height of 13 feet, 10 inches (4.216 meters) (to tip of propeller, in three-point position). With its wings folded, the width of the Bearcat was reduced to 23 feet, 9½ inches (7.252 meters).

The Bearcat’s wings are sharply tapered. Their angle of incidence is −1½°, and there is 5° 30′ dihedral. The leading edges are swept aft 5° 5′. The chord decreases from 9 feet, 7.87 inches (2.943 meters) at the root to 4 feet, 3.5 inches (1.308 meters) at a point 6 inches (15.24 centimeters) inboard from the tip. The total wing area is 244 square feet (22.7 square meters).

The fighter’s horizontal stabilizer has a span of 15 feet, 9 inches (4.801 meters) and a total area of 52.2 square feet (4.85 square meters). Its angle of incidence is +½°. The rudder has a height of 6 feet, 1–13/16 inches (1.875 meters). The vertical tail has a total area of 20.8 square feet (1.93 square meters), and is offset 2° left.

The F8F-1’s empty weight was 7,070 pounds (3,207 kilograms) and maximum takeoff weight was 12,947 pounds (5,873 kilograms). The F8F-2’s empty weight increased to 7,650 pounds (3,470 kilograms), and its maximum takeoff weight was 13,460 pounds (6,105 kilograms).

The production F8F-1 was powered by a Pratt & Whitney Double Wasp 2SC14-G (R-2800-34W) engine which had the same Sea Level power ratings as the R-2800-22. It produced 1,500 horsepower at 2,600 r.p.m. at 18,500 feet (5,639 meters) and had a Military Power rating of 1,700 horsepower at 2,800 r.p.m. at 16,000 feet (4,877 meters). The gear reduction drive ratio was also 0.45:1. A slightly larger Aero Products propeller with a diameter of 12 feet, 7 inches (5.835 meters) was installed. The R-2800-34W was 6 feet, 2.134 inches (1.883 meters) long, 4 feet, 4.80 inches (1.341 meters) in diameter and weighed 2,358.5 pounds (1,069.8 kilograms).

The F8F-2 was powered by a Pratt & Whitney R-2800-30W. The Normal Power rating increased to 1,720 horsepower at 2,600 r.p.m. at Sea Level, and 1,450 horsepower at 22,000 feet (6,706 meters). Takeoff and Military Power also increased: 2,250 horsepower at 2,800 r.p.m. at Sea Level, and 1,600 horsepower at 22,000 feet (6,706 meters). The R-2800-30W also drove an Aero Products propeller. The gear reduction ratio was the same. Its dimensions were slightly different than the -34W: 7 feet, 8.75 inches (2.356 meters) long, and 4 feet, 5.00 inches (1.346 meters) in diameter. The engine’s weight increased to 2,560 pounds (1,161 kilograms).

The Bearcat had a top speed of 336 knots (387 miles per hour/622 kilometers per hour) at Sea Level, and 388 knots (447 miles per hour/719 kilometers per hour) at 28,000 feet (8,534 meters). The airplane had initial rate of climb at Sea Level of 4,465 feet per minute (22.68 meters per second) and it could climb to 20,000 feet (6,096 meters) in 8.4 minutes. Its ceiling was 38,200 feet (11,643 meters).

Fuel capacity is 185 U.S. gallons (700 liters). The fighter’s range could be extended with a jettisonable centerline and two underwing tanks. The Bearcat’s combat radius was 235 nautical miles (270 statute miles/435 kilometers). Its maximum range, with three external tanks (350 gallons/1,325 liters), was 1,595 nautical miles (1,835 statute miles/2,954 kilometers).

The F8F-1 Bearcat was armed with four Browning AN-M2 .50-caliber machine guns. Inboard guns were provided with 325 rounds of ammunition, each, while the outboard guns had 200 rounds per gun. The F8F-2 replaced these with four M3 20 mm autocannon. Each inboard cannon had 325 rounds per gun, and the outboard guns had 188 rounds each. The F8F could also be armed with up to three 11.75-inch (29.845 centimeters) Tiny Tim air-to-ground rockets, or four 5-inch (12.7 centimeter) High Velocity Aerial Rockets (HVAR). For bombing missions, the Bearcat could carry one 1,600 pound (726 kilograms) bomb on the centerline and two 1,000 pounders (454 kilograms, each) under the wings.

The first prototype Grumman XF8F-1 Bearcat, Bu. No. 90460, crashed into Chesapeake Bay during gunnery tests at NAS Patuxent River, Maryland, 18 March 1945. Its pilot was missing, presumably killed. The airplane has recently–probably—been located.²

Robert Leicester Hall was born at Taunton, Massachussetts, 22 August 1905. He was the son of Bicknell Hall, a mechanical engineer, and Estella Beatrice Lane Hall.

Robert L. Hall (Michiganesian of 1927)

Hall attended the University of Michigan, graduating in 1927 with Bachelor of Science degree in Mechanical Engineering (B.S.M.E.). He was a member of the Phi Gamma Delta (ΦΓΔ) fraternity and the glee club. While at the University, Hall became a member of the American Society of Mechanical Engineers.

In 1929 he went to work for the Fairchild Airplane Manufacturing Company at Farmingdale, New York. While there, Hall met his first wife, Eugenie Therese Zeller, a 1928 graduate of Cornell University, and a secretary at the plant. They were married in 1930, and lived in a rented home on St. James Avenue, Chicopee City, Massachusetts. Their son, Robert Jr., was born 5 November 1931. They later divorced.

16 August 1969: Former Lockheed SR-71 test pilot Darryl Greenamyer flew his modified Grumman F8F-2 Bearcat, Conquest I (Bu. No. 121646, FAA registration N1111L) to 776.45 kilometers per hour (482.46 miles per hour) over a 3 kilometer course at Edwards Air Force Base, California.¹ In setting a new Fédération Aéronautique Internationale (FAI) world record speed for piston engine airplanes (Class C-1, Group I), he broke the record that had stood since 1936, set by Fritz Wendel in a prototype Messerschmitt Me 209.² The Bearcat won the National Air Races six times.

Darryl George Greenamyer was born 13 August 1936 at Southgate, California. He is the second son of George Petit Greenamyer, a gold miner, and Bette Bessent Greenamyer, a waitress.

Greenamyer served as a pilot in the United States Air Force, and as a civilian test pilot for Lockheed, flying the Lockheed SR-71A Blackbird. In 1970, he was honored with the Iven C. Kincheloe Award by the Society of Experimental Test Pilots for outstanding professional accomplishment in the conduct of flight testing.

On 21 January 1977, Greenamyer married Miss Mary Terese Croft in a civil ceremony in Arlington, Virginia.

Conquest I was built by the Grumman Aircraft Engineering Corporation in 1948 as an F8F-2 Bearcat, a carrier-based light weight fighter. The production F8F-2 Bearcat was 27 feet, 8 inches (8.432 meters) long with a wingspan of 35 feet, 6 inches (10.820 meters) and overall height of 13 feet, 5 inches (4.089 meters). Its empty weight was 7,070 pounds (3,206.9 kilograms) and maximum takeoff weight was 12,947 pounds (5,872.7 kilograms).

The production F8F-2 used an air-cooled, supercharged, 2,804.4-cubic-inch-displacement (45.956 liter) Pratt & Whitney Double Wasp E12 (R-2800-30W) twin-row 18-cylinder radial engine with a compression ration of 6.75:1. The R-2800-30W was rated at 1,720 horsepower at 2,600 r.p.m. at Sea Level, and 1,450 horsepower at 2,600 r.p.m. at 22,000 feet (6,706 meters). The Takeoff and Military Power ratings were 2,250 horsepower at 2,800 r.p.m. at Sea Level, and 1,600 horsepower at 2,800 r.p.m. at 22,000 feet (6,706 meters). These power ratings required 115/145 aviation gasoline and water/alcohol injection and 115/145 aviation gasoline. The engine drove an Aeroproducts Inc. four-bladed propeller with a diameter of 12 feet, 7 inches (3.835 meters) through a 0.450:1 gear reduction. The R-2800-30W was 8 feet, 2.75 inches (2.508 meters) long, 4 feet, 5.00 inches (1.346 meters) in diameter and weighed 2,560 pounds (1,161.2 kilograms).

The Bearcat had a top speed of 421 miles per hour (677.5 kilometers per hour). It could climb at 4,570 feet per minute (23.2 meters per second) and had a service ceiling of 38,700 feet (11,796 meters). Its range was 1,105 miles (1,778 kilometers).

Conquest I‘s wings were shortened by 7 feet (2.134 meters). The new wingspan is 28 feet, 6 inches (8.687 meters). The R-2800 engine of Greenamyer’s racer was modified to produce 3,100 horsepower. It drove an Aeroproducts propeller from a Douglas AD-6 Skyraider, which had a diameter of 13 feet, 6 inches (4.115 meters). The spinner from a North American Aviation P-51H Mustang was used.

Conquest I is in the collection of the Smithsonian Institution National Air and Space Museum. It was given to the museum by Greenamyer in exchange for an F8F-1 Bearcat, Bu. No. 90446. It is on display at the Steven F. Udvar-Hazy Center, Chantilly, Virginia.
