From its inception to the early 1990s, Aeroflot was the flag carrier and a state-owned enterprise of the Soviet Union (USSR). During this time, Aeroflot grew its fleet to over five thousand domestically-made aircraft and expanded to operate a domestic and international flight network of over three thousand destinations throughout the Soviet Union and the globe, making the airline the largest in the world at the time. In addition to passenger flights, Aeroflot also committed to freight operations and serving the state through transportation and military assistance. Following the dissolution of the USSR, the carrier was restructured into an open joint-stock company and embarked on a radical transformation process. Aeroflot shrank the fleet dramatically while at the same time purchasing Western aircraft and newer domestic models and focusing on expanding its international market share before moving to boost its domestic market share.
