Family of Russian military transport helicopters From Wikipedia, the free encyclopedia
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[update] at two factories, 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.

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.[citation needed]
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.[citation needed]
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. Eight have a loading ramp in place of the usual clamshell doors and can load a vehicle up to the size of an SUV.[citation needed]
In March 2007, licensed production of the Mi-17 started in China, with production being led by Mil Moscow Helicopter Plant JSC and the Sichuan Lantian Helicopter Company Limited in Chengdu, Sichuan province as a joint venture.[1] The plant built 20 helicopters in 2008, using Russian Ulan-Ude-supplied kits; annual production was expected to increase to 80 helicopters. The variants planned to be built by Lantian include the Mi-171, Mi-17V-5, and Mi-17V-7.[2] In 2021 it was reported that China was replacing the Russian-made Mi-17 with their own Z-20, except possibly for the Mi-171Sh assault helicopter; the last Mi-17 order was in 2014.[3]
In 2021 the website of Russian Helicopters, the manufacturer, said that the Mi-8/17 was "the most widely operated helicopter in history."[4]
Royal Cambodian Air Force Mi-17s were used during the Cambodian government's offensives; by 1994 ten operational airframes were in service, with five converted to helicopter gunships equipped with 57 mm S-5 rocket pods, providing air support for ground forces attacking the Khmer Rouge positions. In 1996 the Government launched an offensive during the dry season at the Khmer Rouge stronghold of Anlong Veng and Pailin, using five Mi-17 gunships and eight Mi-17-Mi-8 troops transports.[5]
In May 1999, during Operation Safed Sagar, the Mi-17 was used in the first air phase of the Kargil War by 129HU of the Indian Air Force (IAF) against the Pakistan Army. One IAF Mi-17 and one IAF MiG-21 were shot down by Pakistan Army Air Defence Anza-II shoulder-fired missiles. This led to the withdrawal of armed helicopters and attacks by fixed-wing aircraft in the Kargil theatre.[6]
The Mi-17 was used extensively by the Sri Lanka Air Force in Sri Lanka's war on terrorism by the LTTE. Seven of them were lost in combat and attacks on airports.[7]

This was the largest rescue by two helicopters in USAF history. USAF pilot Lt Col Gregory Roberts received the Distinguished Flying Cross for the mission.[11]
During the Tham Luang cave rescue in July 2018, the Royal Thai Army used the Mi-17 helicopter for searching operations, and evacuating the first batch of survivors from Tham Luang to Chiang Rai hospital;[12] on 10 July 2018 a Mil Mi-17 helicopter took the last evacuated boy to the hospital.[13]

This is the first time the Thai armed forces have acquired Russian aircraft instead of American aircraft.[16] Flight International quotes the Thai Army's rationale: "We are buying three Mi-17 helicopters for the price of one Black Hawk. The Mi-17 can also carry more than 30 troops, while the Black Hawk could carry only 13 soldiers. These were the key factors behind the decision."[17]
On 15 December 2008, it was reported that India ordered 80 Mi-17V-5 helicopters worth $1.375 billion, which would be delivered to the Indian Air Force between 2011 and 2014 to replace aging Mi-8s.[18] In August 2010, it was reported that India planned to order another 59 Mi-17s.[19] The first Mi-17V-5s entered service with India in February 2012.[20] In December 2012, India signed a contract for 71 aircraft at a reported cost of US$1.3 billion.[21][22] In December 2014 it was reported that India is in agreement with the Russian Federation to produce on its territory Mi-17s and Ka-226Ts.[23] All 151 helicopters were delivered as of February 2016.[24]

In 2011, Chief of Staff of the Afghan National Army Abdul Wahab Wardak announced that the US government would buy Mi-17s for use by Afghanistan's troops.
