Mi-6 Hook

The Mi-6 Hook was a landmark Soviet heavy-lift helicopter, first flown in the late 1950s when turbine-powered rotorcraft were still maturing. It was designed to move heavy trucks, tracked vehicles, industrial equipment, and field teams into areas with poor ground infrastructure, including remote Soviet regions. At introduction it was among the world's largest rotary-wing aircraft and gave Soviet aviation a practical heavy-lift tool before the later Mi-26 arrived.

Technically, the Mi-6 used two large turboshaft engines driving a five-blade main rotor and a heavy transport fuselage sized for vehicles, cargo, or troops. A distinctive feature was its small fixed wing, which could carry part of the load in forward flight and reduce rotor demand at speed. The helicopter's size, payload, and range made it valuable for military logistics and civil construction, while its operating demands reflected the complexity of early heavy-lift rotorcraft.

Operationally, the Mi-6 moved troops, vehicles, supplies, and heavy equipment for Soviet and export users, while civil variants supported construction, resource extraction, and remote logistics. It also served as an important stepping stone in Soviet helicopter doctrine: large rotary-wing transport could move payloads directly to dispersed sites where fixed-wing aircraft could not land. Although largely overtaken by the Mi-26 and newer transport methods, the Mi-6 remains historically important as the platform that proved large-scale turbine helicopter lift in regular service.
