The Mil Mi-17 (also known as the Mi-8M series in Russian service, NATO reporting name "Hip") is a Russian helicopter currently in production at two factories in Kazan and Ulan-Ude. It is a medium twin-turbine transport helicopter that can also act as a gunship.
Developed from the basic Mi-8 airframe, the Mi-17 was fitted with the larger TV3-117MT engines, rotors, and transmission developed for the Mi-14, along with fuselage improvements for heavier loads. Optional engines for 'hot and high' conditions are the 1545 kW Isotov TV3-117VM. Recent exports to China and Venezuela for use in high mountains have the new VK-2500 version of the engine with FADEC control.
