The Mikoyan-Gurevich MiG-3 (Russian: Микоян и Гуревич МиГ-3) was a Soviet fighter and interceptor aircraft used during World War II. It was a development of the MiG-1 by the OKO (opytno-konstruktorskij otdel — Experimental Design Department) of Zavod (Factory) No. 1 to remedy problems found during the MiG-1's development and operations. It replaced the MiG-1 on the production line at Factory No. 1 on 20 December 1940 and was built in large numbers during 1941 before Factory No. 1 was converted to build the Ilyushin Il-2. On 22 June 1941, at the beginning of Operation Barbarossa, some 981 were in service with the Soviet Air Forces (VVS), the Soviet Air Defence Forces (PVO) and Soviet Naval Aviation. The MiG-3 was difficult to fly in peacetime and much more so in combat. Originally designed as a high-altitude fighter-interceptor, combat over the Eastern Front was generally at lower altitudes, where it was inferior to the German Messerschmitt Bf 109 as well as most of its Soviet contemporaries. It was also pressed into service as a fighter-bomber during the autumn of 1941 but it was equally unsuited for this. The losses suffered in combat were very high, in percentage the highest among all the VVS fighters, with 1,432 shot down planes. Over time, the survivors were concentrated in the PVO, where its disadvantages mattered less, the last being withdrawn from service before the end of the war. The large number of defects noted during flight testing of the MiG-1 forced Mikoyan and Gurevich to make a number of modifications to the design. Testing was done on a full-size aircraft in the T-1 wind tunnel belonging to the Central Aero and Hydrodynamics Institute (TsAGI) to evaluate the problems and their proposed solutions. The first aircraft to see all of these changes applied was the fourth prototype of the I-200. It first flew on 29 October 1940 and was approved for production after passing its State acceptance trials. The first MiG-3, as the improved aircraft was named on 9 December, was completed on 20 December 1940 and another 20 were delivered by the end of the year. A number of reports had been received about poor quality aircraft received by the regiments which pointed directly at the NII VVS as it was responsible for monitoring the quality of the aircraft delivered to the VVS. On 31 May 1941 the People's Commissariat of Defense decreed that the NII VVS had been negligent. A number of senior managers were demoted and the head of the Institute, Major General A. I. Filin was summarily executed. The number of aircraft built was 3,422. For more details of the design, including the cahanges required to the MiG-1, plus operational history and variants, click here.
