The Antonov An-225 Mega Transport!! Biggest Cargo aircraft

Antonov An-225


The Antonov An-225 airlift cargo aircraft that was designed by the Antonov Design Bureau of the soviet union during the is powered by six turbofan engine and is the worlds heaviest aircraft 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 An-225 has fuselage barrel extensions added fore and aft of the wings. The wings also received root extensions to increase span. Two more Progress D-18T turbofan engines were added to the new wing roots, bringing the total to six. An increased-capacity landing gear system with 32 wheels was designed, some of which are steerable, enabling the aircraft to turn within a 60 m-wide (200 ft) runway. Like its An-124 predecessor, the An-225 has nose gear designed to “kneel” so cargo can be more easily loaded and unloaded. Unlike the An-124, which has a rear cargo door and ramp, the An-225 design left these off to save weight, and the empennage design was changed from a single vertical stabilizer to a twin tail with an oversized, swept-back horizontal stabilizer. The twin tail was essential to enable the plane to carry large, heavy external loads that would disturb the airflow around 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 An-225 had a maximum gross weight of 600 tonnes but from 2000 to 2001 the aircraft underwent modifications at a cost of US$20M such as the addition of a reinforced floor, which increased the maximum gross weight to 710 short tons.

Both the earlier and later takeoff weights establish the An-225 as the world’s heaviest aircraft, being heavier than the double-deck Airbus A380. It is surpassed in other size-related categories, however: Airbus claims to have improved upon the An-225’s maximum landing weight by landing an A380 at 591.7 tonnes during tests and the Hughes H-4 Hercules, known as the “Spruce Goose”, has a greater wingspan and a greater overall height. But the Spruce Goose is 20% shorter and overall lighter, due to the materials used in its construction. In addition, the H-4 only flew once, making the An-225 the largest aircraft in the world to enter service.

The An-225’s pressurized cargo hold is 1,300 m3 (46,000 cu ft) in volume; 6.4 m (21 ft 0 in) wide, 4.4 m (14 ft) high, and 43.35 m (142 ft 3 in)  longer than the first flight of the Wright Flyer.


Antonov is flown by six pilot crew instead of 2 as commercial aircraft or other military aircraft it is 84 meters long and 88.4 metres wingspan 18.4 meters taller with a total wing area of 905 sq. metres.this aircraft weighs 285000 kg with no payload and the maximum takeoff weight of 640000 kg
