The P-39 Airacobra is an American fighter constructed in the late 1930’s by Bell Corporation. According to the Air Force of US Army specification published in 1937 the military needed a high-altitude interceptor, fast, with a descent climb rate and heavily armed. The XP-39 model - “Airacobra” prototype - had its first flight on April 6th 1939. The aircraft had quite an unusual design - with the engine mounted in the rear (with the centre of mass being behind the pilot’s position) increased maneuverability and cockpit protection, but at the same time controlling the aircraft became somewhat unpredictable, the slightest mistake could cause a flat spin, thus even simple maneuvers required 100% concentration. The distinctive feature of most of the “Cobras” was the M4 37mm engine cannon - a powerful weapon but with poor ballistics and only 3 shots per second rate of fire. At first such a characteristics combination was not particularly appreciated by American pilots, who preferred trusted and stable machines with rapid-fire armament.
