AN-225 Myria

The Biggest Bird in The Sky 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. The An-225 is an extension of Antonov's earlier An-124. To meet the needs of its new role, fuselage barrel extensions were added fore and aft of the wings, which received root extensions. Two more Lotarev D-18 turbofan engines were added to the new wing roots, bringing the total to six, and an increased-capacity landing gear system with 32 wheels was designed. The An-124's rear cargo door and ramp were removed to save weight, and the empennage was changed from a single vertical stabilizer to a twin tail with an oversized horizontal stabilizer. The twin tail was made necessary by the requirement to carry very large and heavy external loads, which would disturb the aerodynamics of a conventional tail. Unlike the An-124, the An-225 was not intended for tactical airlifting and is not designed for short-field operation. The An-225 first flew on December 21, 1988. The aircraft was on static display at the Paris Air Show in 1989. Two aircraft were ordered, but only one An-225 (tail number UR-82060) is currently in service. It is commercially available for carrying ultra-heavy and oversize freight, up to 250,000 kg (550,000 lb) internally or 200,000 kg (440,000 lb) on the upper fuselage. Cargo on the upper fuselage can be 70 m long. A second An-225 was partially built during the late 1980s for use by the Soviet space program. Following the collapse of the Soviet Union in 1990 and the cancellation of the Buran space program, the lone operational An-225 was placed in storage. The six Lotarev engines were removed for use on An-124s, and the second An-225 airframe (nearing completion and awaiting engines) was also mothballed.
