Antonov An-22

The Antonov An-22 Antei (Ukrainian and Russian: Антей Antaeus) (NATO reporting name "Cock") was the world's heaviest aircraft, until the advent of the American C-5 Galaxy and later the Soviet An-124. Powered by four turboprops and four respective pairs of contra-rotating propellers, the design remains the world's largest turboprop-powered aircraft. It first appeared outside the Soviet Union at the 1965 Paris Air Show.
