The Mil Mi-6 (NATO reporting name Hook), given the article number izdeliye 50 and company designation V-6, is a Soviet/Russian heavy transport helicopter that was designed by the Mil design bureau. It was built in large numbers for both military and civil roles and used to be the largest helicopter in production until Mil Mi-26 was put in production in 1980
