Antonov An-124 Ruslan

The Antonov An-124 Ruslan, NATO reporting name Condor, is a large four-engined strategic airlift aircraft designed in the 1980s by the Antonov Design Bureau in the Ukrainian SSR of the Soviet Union. Design work began in 1971 under the name Izdeliye 400, answering a shortage of heavy airlift in the Soviet Military Transport Aviation Command, and final assembly lines were set up in Ulyanovsk, Russia, and at the Kyiv Aviation Plant AVIANT in Ukraine. It made its maiden flight on 24 December 1982 and first appeared in the West at the 1985 Paris Air Show. Four Lotarev D-18 turbofan engines power it. After the Soviet collapse it gained civil certification on 30 December 1992 and became a commercial heavy freighter, with 26 in commercial service in 2019. It is the heaviest operating cargo aircraft and the largest military transport aircraft in service, behind only the destroyed An-225, its enlarged derivative.
