world war ii: soviet air forces

P-39 Airacobra of Soviet ace Ivan Gaidaenko, the Airacobra was not well received by the Americans, and the British, who wanted a fighter that could operate well at high altitude, but the lack of a supercharger on the P-39 meant it couldn’t perform well at high altitudes, however this wasn’t a problem on eastern front in the Soviet union, where most air engagements took place at lower altitudes where the P-39 performed well, that along with its heavy armament (Consisting of a 37mm cannon and dual 50s in the nose and either 4 30s in the wings or another pair of 50s) meant it was well received by Soviet pilots.
