The Antonov An-225 Mriya (Ukrainian: Антонов Ан-225 Мрія (dream or inspiration), NATO reporting name: "Cossack") is a strategic airlift cargo aircraft that was designed by the Antonov Design Bureau in the Soviet Union in the 1980s. It is powered by six turbofan engines and is the longest and heaviest airplane ever built, with a maximum takeoff weight of 640 tonnes (710 short tons). It also has the largest wingspan of any aircraft in operational service. The single example built has the Ukrainian civil registration UR-82060. A second airframe was partially built; its completion was halted because of lack of funding and interest.The Antonov An-225, initially developed for the task of transporting the Buran spaceplane, was an enlargement of the successful Antonov An-124. The first and only An-225 was completed in 1988. After successfully fulfilling its Soviet military missions, it was mothballed for eight years. It was then refurbished and re-introduced, and is in commercial operation with Antonov Airlines carrying oversized payloads.[1] The airlifter holds the absolute world records for an airlifted single item payload of 189,980 kilograms (418,834 pounds),[2][3] and an airlifted total payload of 253,820 kg (559,577 lb).[4][5] It has also transported a payload of 247,000 kilograms (545,000 pounds) on a commercial flight.
The Antonov An-225 was designed to airlift the Energia rocket's boosters and the Buran space shuttle for the Soviet space program. It was developed as a replacement for the Myasishchev VM-T. The An-225's original mission and objectives are almost identical to that of the United States' Shuttle Carrier Aircraft.The An-225 first flew on 21 December 1988 with a 74-minute flight from Kiev. The aircraft was on static display at the Paris Air Show in 1989 and it flew during the public days at the Farnborough air show in 1990. Two aircraft were ordered, but only one An-225 (registration CCCP-82060 later UR-82060[9]) was finished. It can carry ultra-heavy and oversize freight, up to 250,000 kg (550,000 lb) internally,[7] or 200,000 kg (440,000 lb) on the upper fuselage. Cargo on the upper fuselage can be 70 metres (230 ft) long.A second An-225 was partially built during the late 1980s for the Soviet space program. The second An-225 included a rear cargo door and a redesigned tail with a single vertical stabilizer. It was planned to be more effective for cargo transportation.[11] Following the collapse of the Soviet Union in 1991 and the cancellation of the Buran space program, the lone operational An-225 was placed in storage in 1994.[12] The six Ivchenko-Progress engines were removed for use on An-124s, and the second uncompleted An-225 airframe was also stored. The first An-225 was later re-engined and put into service.By 2000, the need for additional An-225 capacity had become apparent, so the decision was made in September 2006 to complete the second An-225. The second airframe was scheduled for completion around 2008,[14] then delayed. By August 2009, the aircraft had not been completed and work had been abandoned.[1][15] In May 2011, the Antonov CEO is reported to have said that the completion of a second An-225 Mriya transport aircraft with a carrying capacity of 250 tons requires at least $300 million, but if the financing is provided, its completion could be achieved in three years.[16] According to different sources, the second jet is 60–70% complete.In April 2013, the Russian government announced plans to revive Soviet-era air launch projects that would use a purpose-built modification to the An-225 as a midair launchpad.
