The Mil Mi-6 'Hook' was a Soviet military transport helicopter, which was widely used during the Cold War. Designed by Mikhail Mil in 1954, the prototype V-6 Shestjorka performed its maiden flight on June 5, 1957, and it entered service the following year. It was the first Soviet helicopter fitted with turboshaft engines, instead of piston engines. At the end of the 1950s, it was the largest helicopter in the world. It was also built in large numbers, being also employed by the armed forces of Eastern European countries and by North Korea and North Vietnam.
The Mil Mi-6 Hook was in service with the Red Army, from Europe to the Far East Asia, both as a troop transport and a heavy equipment transporter. Up to 70 well-accoutered paratroopers could be carried or a 13-ton load. Since it was a rear-loading helicopter, equipped with rear clam-shell doors and a ramp, it could also transport military vehicles. It was a very reliable and stable helicopter. The most widely built version was the Mi-6T, which was also acquired by the Peruvian Air Force.
