The Cossack

The An-225 Mriya is a strategic airlift transport aircraft which was built by the Antonov Design Bureau, and is by some measures the largest airplane ever built. The design was an enlargement of the successful An-124 Ruslan. Mriya (Мрія) means "Dream" (Inspiration) in Ukrainian.
The An-225 was designed for the Soviet space program as a replacement for the Myasishchev VM-T. Able to airlift the Energia rocket's boosters and the Buran space shuttle, its mission and objectives are almost identical to that of the Airbus Beluga and the United States' Shuttle Carrier Aircraft.
