|The Mil Mi-26 (Russian Миль Ми-26, NATO reporting name "Halo") is a Russian/Soviet heavy transport helicopter in service in civilian and military roles. It is the heaviest and most powerful helicopter ever to have gone into production.|
The Mi-26 was designed for military and civil use and intended to be able to lift more than any previous helicopter. The first Mi-26 flew on December 14, 1977 and the first entered service in the Soviet military in 1983.
The Mi-26 was the first helicopter to operate with an eight-blade rotor. It is capable of single-engine flight in the event of loss of power by one engine (depending on aircraft mission weight) because of an engine load sharing system.
While it is only slightly heavier than the Mil Mi-6, it can lift more: 20 tons (tonnes) (44,000 lb).
