One model, the F2G utilized the huge 4 row radial engine from Pratt/Whitney, With 36 cylinders, and 4360 cu.in. The F4U-4 variant had the R2800-18W engine and a new four bladed prop. There were many variations of Corsair built over the life of its production, Some models were produced by Vought, some by Goodyear, some by Brewster. By the time of the first production run, the mighty Pratt/Whitney was producing 2000 horsepower for takeoff, and with its two-stage supercharger it would propel the Corsair to a speed of 417 mph at 20,000 feet. In June of 1940, the Navy order 584 of the distinctive fighters. It first flew on May 29, 1940, piloted by Lyman Bullard. In June of that year, the Navy approved the proposal, and placed an order for one prototype. Aerodynamically, having the wing meet the round fuselage at right angles had the advantage of low relative drag at the fuselage/wing joint. This kept the gear leg at its shortest possible length, so that it was strong enough to withstand the hard landing impact, and still provide the height to the fuselage so that the propeller would clear the deck. The landing gear was mounted at the lowest point of the wing. Their solution was to design the wings in an inverted gull-wing shape, coming down from the fuselage at an angle that was perpendicular to the fuselage, and then canting them upwards at a dihedral of 8 ½ degrees.

They also had to consider the demands made on the landing gear of a carrier based plane. In order to utilize all of that power, the design team had to cope with a huge propeller with a diameter of 13 ft. It was rated at 1850 horsepower for takeoff, a significant increase over current fighter power plants. The Vought design group came up with an innovative concept that utilized the power of the new Pratt and Whitney 2800R radial engine.

In early 1938, the Navy issued a set of specifications for a high performance, carrier-based fighter that could match the capabilities of the best land based aircraft, and also live with the operational and storage requirements of an aircraft carrier. Today, most simply refer to the Vought F4U as the Corsair. Japanese sailors called it whistling death. Some called it the bent wing wonder, and some called it hose nose.
