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.

However the aircraft became quite useful on the Eastern Front. Soviet pilots liked the machine for it’s heavy armament, great visibility and despite the drawbacks, the “Cobras” were really maintenance-friendly.

The P-39 series developed into the P-63 Kingcobra. This aircraft was larger and heavier, tailplane and wingtip redesign improved aerodynamics and increased maximum speed. These aircraft were supplied to the USSR from 1944 and despite the agreement not to use them in battles against Germans as they were designed for the Asian theatre, the Soviets secretly replaced their aging Airacobras with the modern P-63’s.

The main opponents of the” Cobras” were the German Bf 109 fighters F and G series. At the beginning of the war installing DВ-601Е and DВ-605А engines with up to 1450 h.p. allowed pilots to increase the speed of Bf’s in excess of 630 km/h, greater maneuverability in comparison with “Cobras” made them a very dangerous opponent. At the beginning of 1943  the new  Bf 109 G-6 fighters arrived at the Eastern Front, they had much better armament - 2x13mm MG’s and MK 108 30mm nose mounted cannon. Thus the last advantage of the “Cobras” - impressive burst mass was gone.From that point Soviet pilots could only count on their own skill.
