The Ilyushin Il-76 is a multi-purpose, fixed-wing, four-engine turbofan strategic airlifter designed by the Soviet Union's Ilyushin design bureau as a commercial freighter in 1967, to replace the Antonov An-12. It was developed to deliver heavy machinery to remote and poorly served areas. Military versions of the Il-76 have been widely used in Europe, Asia and Africa, including use as an aerial refueling tanker and command center.
