How was the Antonov An-225 destroyed and why was it unique?

In our Aviation & Real-World Flying coverage, the Antonov An-225 Mriya was the sole completed six-engine heavy-lift aircraft built for the Buran shuttle. The 84-metre-long aircraft spanned 88.4 metres and had a 640-tonne maximum take-off weight. It was destroyed while parked in its Hostomel hangar during Russia’s February 2022 assault, not shot down.

How was the Antonov An-225 destroyed at Hostomel?

Mriya was lost to combat and fire damage inside its maintenance hangar, not during a flight. Russian airborne forces attacked Antonov Airport on 24 February 2022, at the start of Russia’s full-scale invasion of Ukraine, and the repeatedly contested airfield became a major battleground.

The site is variously called Antonov, Hostomel or Gostomel Airport. Ukraine announced Mriya’s destruction on 27 February, but that was the announcement date rather than a proven time of impact; safely inspecting the hangar was impossible while fighting continued.

Images taken after Ukrainian forces regained access showed a burnt-out cockpit and forward fuselage, severe damage around the centre structure and collapsed hangar sections covering the wreck. Parts of the rear fuselage and tail remained recognisable, but the completed aircraft was an operational and structural total loss.

Was the An-225 bombed or shot down?

No public evidence supports a shoot-down: the aircraft was parked in its hangar when it was destroyed. Ukrainian authorities and Antonov attributed the loss to attacking Russian forces, although accounts describe the damaging event variously as bombing, shelling or a strike on the hangar.

• Established: Mriya suffered catastrophic combat and fire damage on the ground during the battle for the airport.
• Official attribution: Ukraine and the aircraft’s operator blamed Russian forces.
• Unresolved publicly: The exact munition, point of impact and sequence that started the fatal fire.

Claims that a particular bomb, missile or artillery shell has been identified conclusively go beyond the widely available evidence.

Why was Mriya not evacuated?

The An-225 was undergoing engine maintenance and was not ready for a normal departure when the attack began. Antonov stated that one of its six engines had been removed for repairs.

A six-engine aeroplane cannot simply depart on five engines without an approved configuration, maintenance release, prepared crew, fuel, route and usable runway and airspace. Once Hostomel was under assault, refitting or towing an aircraft of this size to safety was not realistic.

Former employees later disputed whether Mriya could have been moved before the invasion. That raises questions about earlier planning and management decisions, but it does not establish that the aircraft was flight-ready on 24 February.

Why was the An-225 built?

The An-225 was designed to transport the Soviet Buran space shuttle and Energia rocket hardware too large for an ordinary cargo hold. Antonov developed it in Kyiv from the An-124 Ruslan design, lengthening the fuselage, enlarging the wing and adding two engines.

Buran rode on attachment points above the fuselage, much as the Space Shuttle travelled on NASA’s carrier aircraft. Mriya—Ukrainian for “Dream”—first flew on 21 December 1988 and flew with Buran mounted above its fuselage in 1989.

What made the Antonov An-225 unique?

Mriya combined six-engine power, outsized internal and external cargo capability and specialised loading gear in a configuration found on no other operational transport aeroplane.

• Six turbofan engines: Its enlarged wing centre section accommodated an additional pair of Progress D-18T engines, bringing the total to six.
• Twin-fin tail: Widely spaced vertical fins remained effective outside the disturbed airflow created by Buran or another load carried above the fuselage.
• Opening nose and kneeling gear: The nose swung upwards and the forward undercarriage lowered the fuselage for loading. Unlike the An-124, the An-225 omitted a rear cargo door and ramp, reducing structural weight.
• Thirty-two-wheel undercarriage: The numerous wheels spread its weight across the pavement, while steerable main-gear units helped the long aircraft turn.
• Two cargo modes: Freight could travel inside the hold or be secured externally above the fuselage.

Simmers can examine these defining features in our flyable Microsoft Flight Simulator recreation of Mriya’s six-engine, twin-tail layout.

How big was the Antonov An-225?

The sole completed aircraft, registration UR-82060, was 84 metres long, 88.4 metres across the wings and 18.1 metres high. Its dimensions and weight made it the heaviest aeroplane to enter operational service.

Some references give a 600-tonne maximum take-off weight. That was an earlier rating; 640 tonnes is the later uprated maximum normally associated with Mriya’s final operational form.

Maximum take-off weight includes the aeroplane itself, fuel, crew and payload. It does not mean the An-225 could carry 640 tonnes of cargo.

How much cargo could the An-225 carry?

The cargo compartment enclosed roughly 1,300 cubic metres, while the quoted structural payload limit was 250 tonnes. It carried generators, turbines, vehicles, industrial machinery and emergency freight that smaller transports could not accept.

That 250-tonne figure was not a guarantee that any object of that weight could fly. Nose-opening clearance, cargo dimensions, floor loading, centre of gravity and available securing points could all impose a lower limit. Fuel required for the route also reduced usable payload; our performance analysis explains how payload, range, speed and runway requirements constrained one another.

Was the An-225 the world’s biggest aircraft?

By maximum take-off weight, the An-225 was the heaviest aeroplane ever to enter operational service, but “biggest” depends on the measurement. At 84 metres, it was longer than any conventional aeroplane placed in regular service.

Its 88.4-metre wingspan was not the widest ever flown. The Hughes H-4 Hercules spanned about 97.5 metres, while the Stratolaunch aircraft spans roughly 117 metres. Mriya was also lower than the Airbus A380 despite being longer and having a wider wing.

Compared with the Boeing 747-8, the An-225 was about 7.7 metres longer and its wingspan was roughly 20 metres greater. Our comparison of the An-225 and Boeing 747 dimensions and carrying roles explains why the two aircraft served very different purposes.

Why was only one An-225 completed?

Only one An-225 was completed because the Buran programme ended and the intended fleet lost its original purpose. Construction of a second airframe stopped at a partial stage; it was never completed or flightworthy.

The first aircraft was stored after the Soviet space programme collapsed, then refurbished and returned to service with Antonov Airlines in 2001. It subsequently transported generators, industrial equipment and emergency cargo while setting multiple payload records.

Its commercial work did not justify a production fleet. Operating costs were extreme, the market for such loads was narrow and relatively few airports could accommodate the aeroplane and its loading arrangements.

What did the An-225’s size mean at an airport?

A sufficiently long runway alone did not make an airport suitable for the An-225. Planners also had to assess pavement strength, taxiway width, turning space, stand clearance, wingtip obstacles and access for specialised loading equipment.

Departure weight, temperature, elevation and wind altered the runway distance required for each flight. Its 88.4-metre span and long wheelbase also demanded careful routing while taxiing and parking; a runway capable of handling the take-off did not guarantee that the aircraft could reach a usable stand.

Can the Antonov An-225 be rebuilt?

The original Mriya cannot simply be repaired around its burnt forward and centre structures. Any reconstruction would be closer to completing a new aircraft using the unfinished second airframe, recoverable components from UR-82060, newly manufactured structures and modernised systems.

Engineering assessment, certification and funding would be substantial. Public statements of intent and estimated costs are not a fixed production schedule; our examination of what survives and what a proposed An-225 reconstruction would require covers that distinction in detail.
