A variant of the Mi-8, development of the Russian-made Mi-8MT (NATO Designation: 'Hip-H') began in 1967; production started in 1975.  Maximum internal and external payloads are both 4000 kg.  Unlike the Mi-8T, the turboshaft engine is equipped with deflectors to prevent dust intake; a 7.62 mm machine gun is also built onto the military-transport helicopter.  The cabin capacity is 24 passengers in addition to the two crew.

The export version is known as the Mi-17.
