The Bell P-63 Kingcobra is an American fighter aircraft developed by Bell Aircraft in World War II from the Bell P-39 Airacobra in an attempt to correct that aircrafts deficiencies. Although the P-63 was not accepted for combat use by the United States Army Air Forces, it was adopted by the Soviet Air Force.
The P-63 originated from the XP-39E prototype and retained the Bell trademark tricycle landing gear as well as the automobile-type cockpit doors and engine behind the cockpit. The 37 mm cannon that fired through the propeller hub was kept as well as the two synchronized .50 caliber machine guns in the nose and two additional .50 caliber guns located in under-wing pods, similar to the P-39Q.

The first P-63 prototype flew on December 7, 1942, exactly one year after Pearl Harbor and Bell’s chief test pilot, Bob Stanley, did not hesitate to compare it to the Supermarine Spitfire.3 The first two prototypes were lost due to mechanical failures—one prototype suffered a landing gear failure and the second suffered an engine failure by swallowing a valve. An improved 1,325 hp Allison V-1710-93 engine, with a war emergency rating of 1,500 hp was installed on the third prototype, in lieu of the Rolls-Royce Merlin which had been originally planned. This made it one of the fastest Kingcobras built with a the top speed of 421 mph (678 km/h) at 24,100 ft. (7,300 m). |
