Antonov An-225 Mriya Strategic airlifter

The Antonov An-225 Mriya (dream) is a one-off transport aircraft. Currently it is the world’s largest transport aircraft. Also it is the longest and heaviest aircraft ever built. It was developed in the 1980s specially for the Soviet space program. The only Soviet factories, capable of building a high-tech Buran spacecraft, were located around Moscow. However the Baikonur cosmodrome was located in Kazakhstan, approximately 2,100 km from Moscow. The Buran could not be transported by road or rail due to its oversized dimensions. So the Soviets needed a large cargo aircraft to carry the spacecraft.


So in its mission the An-225 is similar to the US Boeing 747 Shuttle Carrier Aircraft. The first An-225 was completed in 1988 and made its maiden flight during the same year. During this flight the aircraft set 110 world records. Its reporting name in the West was Cossack.

  The An-225 is a larger version of the An-124 and uses a number of its components, such as the same engines and avionics. However the An-225 has got 6 engines instead of 4. It is worth noting that the smaller An-124 is currently the world’s largest production military transport aircraft.

The An-225 Mriya has three variants: An-224, An-225-100 and An-325.

An-224 is the original designation of An-225. This variant features an additional rear cargo door.

An-225-100 is an improved version of the An-225. This variant is upgraded with better communication gear, navigation equipment and a traffic collision avoidance system (TCAS) for use in commercial operations.

An-325 is an extended variant of An-225. It is fitted with an additional engine on each in-board pylon, which increases the payload carrying capacity.

The Antonow An-325 was a planned enlarged and improved version of the Antonow An-225, which was never built. The An-225 was the largest production aircraft in the world and is designed to carry heavy loads on its back. The An-225 was initially designed to transport the Soviet Buran space shuttle and would be capable of launching the estimated 275-ton orbiter.

The AN-325 aircraft would have two additional engines, which should be mounted on the respective engine mounts in a manner similar to the American B-52. There would be an eight-jet plane with six engine gondolas. The aircraft, which never went beyond the planning stage, was intended as a launch platform for Russian and foreign spacecraft. It would have become by far the largest and most powerful aircraft in the world. Source

A total of 2 giant aircraft were planned to be built. However only one was completed. Work on the second airframe was abandoned in 2009 and it is still incomplete. Its current completion is around 60-70% and at least $300 million are required to finish the work. It is likely that it will never be completed, because there is no demand for another such large aircraft.

China Will Resurrect The World’s Largest Cargo Plane: Here


On August 30, members of the Aviation Industry Corporation of China (AICC) and the Antonov Corporation, the leading Ukrainian aviation company, signed an agreement to restart production of the AN-225, the world’s largest cargo plane.

The 640 ton, six engine An-225 is the world’s largest aircraft. Measuring at 84 meters in length and a wingspan of over 88 meters, it carries a world record payload of 250 tons (to put this into comparison, it can carry around 300,000 lbs more than the US military’s Boeing made C-17). The sole operational An-225 began flying in 1988, initially carrying the Soviet Buran, a 105 ton reusable spaceplane, on its back. It was put into storage after the Soviet collapse, but restored and put into commercial service in 2002. Since then it has been rented out, flying super heavy cargos like gas and wind turbines, as well as military supplies for NATO forces in the Middle East.


In 1989 the An-225 made its first flights with Buran space shuttle. In 1991, after collapse of the Soviet Union the aircraft was passed on to Ukraine. The Buran space program was taken over by Russia, but eventually in 1993 it was cancelled due to funding problems. So the aircraft lost its only role, that t is was specially designed for. In the former Soviet Air Force a smaller An-124 was used to carry tanks and other military equipment. Still though the An-225 had a large cargo compartment, and had the capability to carry various loads. In 1994 the sole operational An-225 was placed into storage, together with the second incomplete airframe. Until the late 1990s the aircraft was neglected. Some of its parts were cannibalized to keep other An-124 aircraft operational.


In the year 2000 the sole An-225 was re-engined, refurbished and modified for heavy cargo transport. It flew again in 2001. The aircraft received international certificates and since 2002 it is in commercial use by the Ukrainian Antonov Airlines. Currently it operates from London Luton airport. This aircraft carries ultra-heavy and oversized loads, that are too heavy or do not fit inside the smaller An-124. From time to time it carries various military cargo.



This giant aircraft can carry a whooping 250 t of cargo internally, or 200 t externally. For example the US C-5M Super Galaxy can carry only 140 t internally. The An-225 can carry 16 shipping containers, or up to 80 passenger cars.


Its cargo hold has a titanium floor. Nose of the aircraft folds upwards. The aircraft can kneel in a nose-down position to ease loading and unloading operations. Range with maximum payload is 4 000 km.

In fact the first flight of refurbished aircraft in commercial service was with military cargo. In Januarry 2002 the An-225 flew from Germany to Oman with 216 000 ready meals for American military personnel, based in the region. This vast number of ready meals weighted 187.5 t and was transported on 375 pallets.


The An-225 has been contracted by the US and Canadian governments to airlift military supplies to the Middle East in support of coalition forces. This aircraft can quickly transport huge quantities of supplies. A number of times the Antonov An-225 demonstrated its impressive capabilities by carrying 4 to 5 main battle tanks.


Since 2002 the An-225 has become the workhorse of the Antonov Airlines fleet. This aircraft transported objects that were previously thought impossible to move by air.


The An-225 is operated by a crew of 6-7 men, including two pilots, technicians and loadmaster.

Flight deck



The aircraft features an IFR compatible, all digital flight deck, which can accommodate six crew including a pilot, co-pilot, navigator, radio operator and two flight engineers. The flight deck is incorporated with automated navigation and flight control systems for quick analysing and servicing.

The first An-225 aircraft, that is currently active, was optimized for external loads. It lacks rear cargo doors, as lack of such feature allowed to decrease the weight of the aircraft. Also it has twin vertical stabilizers.

The second airframe, that is currently incomplete, had some design changes. It was planned to be more effective for cargo transportation. The second aircraft has a rear cargo door and a redesigned tail with a single vertical stabilizer.
