The Mil Mi-10 (NATO reporting name Harke), given the product number izdeliye 60, is a Soviet military transport helicopter of flying crane configuration, developed from the Mi-6, entering service in 1963. Foregoing the requirement to carry palleted or podded cargoes, Mil redesigned the Mi-10 with a much shorter, fixed, four-leg undercarriage and replaced the extendible escape chute with a gondola fitted with flying controls for a pilot to fly the aircraft during slung load operations. The remainder of the aircraft is essentially identical with the long-legged version. Seventeen of the new flying crane were produced as the Mi-10K. The Mi-10 ("R") has held seven world records, none of which are still current, in the FAI E1 General class for rotorcraft powered by turbine engines.
