The F4U-4 Corsair was the last variant to be produced during WWII, entering service four months before the end of hostilities. It had the dual-stage, supercharged R-2800-18W engine which produced 2,100 hp (1,566 kW) of power. When the cylinders were injected with the water/alcohol mixture, power was boosted to 2,450 hp (1,827 kW). The aircraft required an air scoop under the nose and the unarmored wing fuel tanks of 62 U.S. gal capacities were removed for better maneuverability at the expense of maximum range. The propeller had one additional blade, bringing the total to four blades. Maximum speed was increased to a blistering 448 mph (718 km/h) and climb rate increased to over 3,800 fpm (1,180 metres per minute) as opposed to the 2,900 fpm (884 metres per minute) climb of the F4U-1A. The flight ceiling also increased significantly from 37,000 ft. (11,278 m) to 41,000 ft. (12,497 m). The "4-Hog" retained the original, 6x .50 cal armament and had all the external loads (i.e. drop tanks, bombs, etc.) of the F4U-1D. The armored windshield was now flat to avoid optical warping, unlike the curved, armored windshields of the earlier Corsairs.
