The Curtiss P-40 Warhawk was a single-seat fighter and ground attack aircraft developed by the United States in 1938.

Description

It began as a modified version of the P-36 Hawk, an aircraft that Curtiss had previously built. It was equipped with a single engine (normally an Allison V-1710 V-12[N 1]), two .50 in (12.7 mm) machine guns in the nose, and two .303 Browning machine guns on each wing. Later versions, however, would have three .50 in (12.7 mm) guns in each wing. The P-40 was produced until November 1944, and was used in the air forces of 28 nations, including Great Britain.

History

Development

Development began with the XP-40, which was the 10th production example of the P-36. This was fitted with an Allison V-1710-19 (C-13) inline engine, under the terms of a USAC order dated 30th July 1938.[3] The type's first flight on 14 October 1938[4] revealed a lack of speed, which was resolved by moving the radiator from the belly to the underside of the engine cowling. This increased top speed from 299 mph (481 km/h) to 342 mph (550 km/h).[3] and resulted in the placing of an order for 524 production examples on 27th April 1939. The first of these, powered by a V-1710-33 (C-15) and fitted with a pair of fuselage mounted Browning M2 Machine Guns, made it's initial flight on 4th April 1940, and was followed by another 198 P-40s. These were followed by 131 P-40Bs with pilot armour, self sealing fuel tanks and a 0.3 in guns in each wing, and led to the P-40C, which was basically a P-40B with an additional 0.3 in gun in each wing.[4]

These were followed by the P-40D (Hawk 87A-2), fitted with a new series of Allison engine, resulting in a shorter nose and deeper radiator housing. The fuselage mounted guns were deleted, with armament being standardised as six 0.5 in M2 Machine Guns mounted in the wings.[5] The similar P-40E (Hawk 87A-3), which primarily differed in having the P-40D's cannon provision deleted,[6] became the first P-40 variant built in large numbers after the Bombing of Pearl Harbor, with 2,320 built on American contracts, supplemented by 1,500 built for the RAF as the Kittyhawk Mk IA.[7]

Combat Service

Japan

A number of captured P-40Es were used by the 50 Hiko Sentai of the IJAAF to defend Japanese occupied Rangoon during 1943. On 21 March 1943 a combination of factors resulted in a number of Mitsubishi Ki-21 bombers, which were returning from an attack against Feni Airfield, being shot down by Japanese flown P-40s operating from Mingaladon.[8]
