            developed the license built Wright R-1820
            Cyclone (M-25) into the M-62.  This engine had a
            two-stage supercharger and an improved induction system.
             In 1941, the Soviet Union changed its aircraft and
            engine designations to a constructor system.  The M-62 was
            redesignated the ASh-62.  Including the related M-63,
            over 67,000 were produced.
