 Later, an improved MiG-3 was developed, and by 1942, Mikoyan and Gurevich's team was made an independent design bureau, known informally as MiG, but formally as OKB-155 (which stands for Experimental Design Bureau in Russian).Throughout the Cold War, OKB-155 churned out some of Russia's most important jet aircraft.According to Siddiqi, technical information captured from defeated Germany played a substantial role in OKB-155 rolling out the USSR's first jet fighter, the MiG-9, in 1946.
