During F4U-4 production, three were modified as prototypes for the F4U-5 model and were designated XF4U-5. On February 6, 1946, the Navy gave Chance Vought a letter-of-intent on the company’s proposal to build the F4U-5. Equipped with a new Pratt and Whitney engine and a sidewheel supercharger, it was a high-altitude fighter, designed to fight at 45,000 feet. The F4U-5 housed a R-2800-32W engine, developing approximately 2,300 horsepower which was 200 horsepower more than the “C” engine used in the F4U-4. The engine also maintained greater power to a higher critical altitude than did its predecessor. Maximum speed was listed at 469 miles per hour at 26,800 feet, rate-of-climb was 3,780 feet/min at sea level.
A redesigned cowl had air inlets at 4 o’clock and 8 o’clock. The entire outer-wing panels, for the first time on any Corsair, were metal covered. A substantial reduction in drag resulted. Spring tabs for use on the elevator and rudder controls reduced pilot effort as much as 40 percent. Guns and pitot tubes were electrically heated. The nose was dropped about 2 degrees to improve longitudinal stability and vision. Production began in 1946 with an order for 223. At that time, interest in night and all-weather fighters had grown to such an extent that the Navy ordered a large number of airplanes in the first group converted to night fighters (F4U-5N’s). This version is easily distinguished by its two-foot diameter radar dome in the leading edge of the right wing.
The F4U-5P was a long-range photo-reconnaissance airplane and was equipped with a unique rotating camera mount. Despite the 45,000-foot high-altitude capability, in actual use the F4U-5 would not require such an option. Its combat would be nearly all low-level, where the tremendous payload was eminently useful. When necessary, over 5000 pounds of ordnance could be carried on the twin underwing pylons and the centerline rack. And there were times when it was necessary.
