This post is for my Friend..Peter Worldman, a great humanitarian and a lover of flying objects...big and small.
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 United States' Shuttle Carrier Aircraft.
The An-225 first flew on 21 December 1988. 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 (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 metres (230 ft) long. A second An-225 was partially built during the late 1980s for use by the Soviet space program. The design of the second An-225 included a rear cargo door and a redesigned tail with a single vertical. It would be more effective for cargo transportation. 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 in 1994. 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, it had become apparent of the need for additional An-225 capacity, the decision was made in September 2006 to complete the second An-225. The second airframe was scheduled for completion around 2008. then delayed. By August 2009, the aircraft had not been completed and work had been abandoned.

In the late 1980s, efforts were begun by the Soviet government to generate revenue from its military assets. In 1989, a holding company was set up by the Antonov Design Bureau as a heavy airlift shipping corporation under the name "Antonov Airlines", based in Kiev, Ukraine and operating from London Luton Airport in partnership with Air Foyle HeavyLift. As the Soviet space program was in its last years, the An-225 was considered and accepted to be the prime way to transport the Buran Shuttle. The Buran Shuttle was a spacecraft much like the United States' Space Shuttle.
The company initiated operations with a fleet of four An-124-100s and three Antonov An-12s, but by the late 1990s a need for aircraft larger than the An-124 became apparent. In response, the original An-225 was re-engined, modified for heavy cargo transport, and placed back in service under the management of Antonov Airlines.
On 23 May 2001, the An-225 received its type certificate from the Interstate Aviation Committee Aviation Register (IAC AR). In September 2001, carrying a record load of 253.82 tonnes (279.79 short tons) of cargo, the An-225 flew at an altitude of 2 km (6,600 ft) over a closed circuit of 1,000 km (620 mi) at a speed of 763.2 km/h (474.2 mph). The type's first flight in commercial service departed from Stuttgart, Germany on 3 January 2002, and flew to Thumrait, Oman with 216,000 prepared meals for American military personnel based in the region. This vast number of ready meals was transported on some 375 pallets and weighed 187.5 tons.
Since then, the An-225 has become the major workhorse of the Antonov Airlines fleet, transporting objects once thought impossible to move by air, such as locomotives and 150-ton generators, and has become a valuable asset to international relief organizations for its ability to quickly transport huge quantities of emergency supplies during disaster relief operations.
Beginning in June 2003, the An-225, along with An-124s, delivered over 800 tons of equipment to aid humanitarian efforts in Iraq.
The An-225 has also been contracted by the Canadian and U.S. governments to transport military supplies to the Middle East in support of Coalition forces.
In November 2004, FAI placed the An-225 in the Guinness Book of Records for its 240 records.
On 11 August 2009, the heaviest single cargo item ever sent via airfreight was loaded onto an Antonov 225. At 16.23 metres (53.2 ft) long and 4.27 metres (14.0 ft) wide, the consignment–a generator for a gas power plant in Armenia and its loading frame–weighed in a record 189.09 tonnes (416,900 lb). During 2009 the An-225 was painted in a new blue and yellow paint scheme.
Based on Antonov's earlier
An-124, the An-225 has fuselage barrel extensions added fore and aft of the wings, which received root extensions. Two more
Ivchenko Progress D-18T 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 essential to enable the plane to carry very large and heavy external loads, which would otherwise 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.
Initially the 225 had a maximum gross weight of 600 tonnes (1,320,000 lb) but the aircraft was modified in 2000-01, at a cost of US$20M, with a reinforced floor which allowed increasing the maximum gross weight to 640 tonnes (1,410,000 lb) Both the earlier and later takeoff weights establish the An-225 as the world's heaviest aircraft, being heavier than the double-decker
Airbus A380 even though Airbus plans to pass the An-225's maximum landing weight with 591.7 tonnes (1,304,000 lb) for the A380. The
Hughes H-4 Hercules, known to most as the "Spruce Goose", had a greater wingspan and a greater overall height, but was considerably shorter, and due to the materials used in its construction, also lighter. In addition, the Hercules only flew once and never climbed above 21.3 m (70 ft), making the An-225 the largest aircraft in the world to take off multiple times. The An-225 is not only larger than the
Airbus A380 airliner, it is also considerably bigger than the
Antonov An-124,
Boeing 747 Large Cargo Freighter, and Lockheed
C-5 Galaxy, the nearest equivalent heavy cargo aircraft.
