Antonov An-225 Mriya Low-poly 3D model

The Antonov An-225 Mriya (Ukrainian: Антонов Ан-225 Мрія, lit. ''dream' or 'inspiration''; NATO reporting name: Cossack) was a strategic airlift cargo aircraft that was designed by the Antonov Design Bureau in the Ukrainian SSR within the Soviet Union during the 1980s. Originally, this unique aircraft was developed as an enlargement of the Antonov An-124 to transport Buran-class orbiters. After successfully fulfilling its Soviet military missions, it was mothballed for eight years. It was then refurbished and reintroduced into commercial operation with Antonov Airlines, carrying oversized payloads. While a second airframe with a slightly different configuration was partially built, construction was halted more than once due to a lack of funding and interest. This second aircraft was last brought up to 60–70% completion in 2009.

As an oversized aircraft, the Antonov An-225 Mriya held multiple records which included; heaviest aircraft ever built, and largest wingspan of any aircraft in operational service. Other records held by the An-225 were cargo related in terms of weight and length as the Antonov An-225 had the capability to carry up to 640 tonnes (705 short tons). The An-225 attracted a high degree of public interest, attaining a global following due to its size and its uniqueness. People frequently visited airports to see its scheduled arrivals and departures.

The An-225 was at Hostomel Airport when Russian forces launched an attack on the airport on 24 February 2022, as part of the invasion of Ukraine. The aircraft was destroyed in the attack.
