Bell P-39 Airacobra aircraft played a vital role in Allied air power, especially during the first part of World War II. Although not suitable for operating at higher altitudes, due to having only a single stage supercharger, they proved a formidable adversary when operating below 12,000 feet.
The Airacobra was equipped with a 37 mm cannon, firing through the propeller hub. There were a pair of 12.7 mm machine guns in the nose and four 7.62 mm machine guns in its wings. This made it one of the most heavily armed single engine Allied fighter planes of World War II.
It is said that at speeds below 235 mph, the Bell P-39 Airacobra could out turn, out dive and out roll most aircraft of its time, even formidable Japanese front line fighters. The reason for the excellent low speed and low altitude performance was the location of its engine, behind the pilot. Its placement permitted a very streamlined fuselage, having much less frontal area than aircraft that had their engines located in their noses. The mid engine location of the engine provided room in the nose of the aircraft for its cannon and machine guns.
Airacobras were widely used by the Soviet air force for both air to air combat, ground attack, and troop support. Successful Soviet aces claimed over 50 air to air victories while piloting the aircraft.
One would think that the 37 mm cannon would make the Aircobra an excellent aircraft for use by the Soviets against German tanks. However, the United States chose to supply the Soviet Union only with high explosive 37 mm shells, not the armor piercing type. This made the 37 mm cannon equipped aircraft more useful against “soft” targets. The aircraft were also active in the Pacific Theatre where they were successfully used against Japanese ground forces.
A total of 9,584 Bell P-39 Airacobra aircraft of all types were produced of which approximately 5,000 were supplied to the Soviet Union.
