The Shvetsov M-82 was the most important Soviet radial engine of World War II. Using the M-62 cylinder with a shortened stroke, Shvetsov developed a 14-cylinder, two row radial engine. This engine was qualified at 1,250 hp in 1940.
In 1941, the Soviet Union changed its aircraft and engine designations to a constructor system. The M-82 was redesignated the ASh-82. Over 70,000 were produced including all variants.
