Mil Mi-17
family of Russian military transport helicopters
The Mil Mi-17 (NATO reporting name: Hip) is a Soviet-designed Russian military helicopter family introduced in 1975 (Mi-8M), continuing in production as of 2024 at two factories in Russia, in Kazan and Ulan-Ude. It is known as the Mi-8M series in Russian service. The helicopter is mostly used as a medium twin-turbine transport helicopter, as well as an armed gunship version.
Development
Developed from the basic Mi-8 airframe, the Mi-17 was fitted with the larger Klimov 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 1,545 kW (2,072 shp) Isotov TV3-117VM. Recent exports to China and Venezuela for use in high mountains have the new Klimov VK-2500 version of the Klimov TV3-117 engine with FADEC control.
The designation Mi-17 is for export; the Russian armed forces call it the Mi-8MT. The Mi-17 is recognisable by the tail rotor on the port side instead of the starboard side, and dust shields in front of the engine intakes. Engine cowls are shorter than on the TV2-powered Mi-8, not extending as far over the cockpit, and an opening for a bleed air valve outlet is present forward of the exhaust.
Actual model numbers vary by builder, engine type, and other options. As an example, the sixteen new Ulan Ude-built machines delivered to the Czech Air Force in 2005 with -VM model engines were designated as Mi-171Sh, a development of the Mi-8AMTSh. Modifications include a new large door on the right side, improved Czech-built APU, and Kevlar armour plates around the cockpit area and engines.
This brief starts where responsible research should: with the source description of “Mil Mi-17” as family of Russian military transport helicopters. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as family of Russian military transport helicopters. Its deeper value depends on whether names, dates, institutions and citations support that framing.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q317288. The Library of Congress control number is sh2013001217. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1975, 2024 and 2005.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
