The MiG-3 was a Soviet WWII fighter plane developed from the MiG-1 in an attempt correct the MiG-1s problems. Even though it never fully corrected the MiG-1s problems, the MiG-3 was considered a success. The MiG-3 was designed as a high altitude interceptor. At altitudes above 16,000 feet the plane performed well, being a match for any German fighter. However, since most of the combat against the German invasion took place at low altitudes, the MiG-3 did not perform well as a ground attack plane and was soon withdrawn from the front lines. In the Spring of 1942 the MiG-3 was moved to the air defense squadrons which flew them for the rest of the war. The MiG-3 had a maximum speed of 400 mph and was armed with 1 12.7 mm UBK machine gun, 2 7.62 mm ShKAS machine guns and could carry 2 more UBK machineguns or 2 100 kg bombs or 6 82 mm RS-82 rockets under the wings but this negatively affected flight performance. About 3,322 MiG-3s were produced. This model shows a MiG-3z.6 flown by Capt. A. V. Shlopov of 6 IAP, 6 IAK (Fighter Air Corps), IA-PVO (Moscow Air Defense) in the winter of 1941 / 42.
