During the 1980s, the Antonov Design Bureau in the Ukrainian SSR of the Soviet Union created the Antonov An-225 Mriya, a strategic airlift cargo aircraft. Originally, this one-of-a-kind aircraft was designed to transport Buran-class orbiters as an expansion of the Antonov An-124.

Ukraine’s Antonov-225 freight jet, the world’s largest plane, was destroyed by Russian attacks near Kyiv on the fourth day of Moscow’s invasion, according to Ukraine’s state-owned Ukroboronprom organization.

“Russian invaders destroyed the flagship of Ukrainian aviation, the AN-225”, the organization stated in a statement, referring to the Antonov airfield in Gostomel, near Kyiv.

The aircraft was one-of-a-kind in the world, measuring 84 meters (276 feet) in length and capable of transporting up to 250 tonnes (551,000 pounds) of cargo at a top speed of 850 kilometers per hour (528 mph).

It was given the name “Mriya,” which means to “dream” in Ukrainian.

Ukraine’s Foreign Minister Dmytro Kuleba tweeted Sunday, “This was the world’s largest aircraft, AN-225 ‘Mriya'”
