The Mil Mi-17 (NATO reporting name "Hip") is a Russian helicopter in production at two factories in Kazan and Ulan-Ude. It is known as the Mi-8M series in Russian service. It is a medium twin-turbine transport helicopter. There are also armed gunship versions.

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 1545 kW (2070 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; Russian armed forces call it Mi-8MT. The Mi-17 can be recognized because it has 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, Kevlar armor plates around the cockpit area and engines. Eight have a loading ramp in place of the usual clamshell doors, and will load a vehicle up to the size of an SUV.

In May 2008 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. The plant built 20 helicopters in 2008, using Russian Ulan-Ude-supplied kits; production is expected to reach 80 helicopters per year eventually. The variants to be built by Lantian will include Mi-171, Mi-17V5, and Mi-17V7.[2]

Operational history

Service usage

Mi-17s were used during the Cambodian government's 1996 dry season offensive, five of them being converted to helicopter gunships equipped with 57mm rocket pods and providing air support for ground forces attacking the Khmer Rouge stronghold of Pailin.

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 against Pakistani regular and Pakistan-backed militant forces. One Mi-17 was downed by a shoulder-fired missile, and a fighter aircraft was lost in combat. This led the withdrawal of armed helicopters and attacks by fixed-wing aircraft began.[3]

The Mi-17 was used extensively by the Sri Lanka Air Force in the Sri Lankan Civil War. Seven of them were lost in combat and attacks on airports.[4]

The Mi-17 was used by the Colombian Army in Operation Jaque.

In 2001, the Macedonian Air Force used the Mi-17 against Albanian insurgents.

The Mi-17 is also used by search and rescue teams such as the Malaysian Fire and Rescue Department.

Executive Outcomes used them extensively in its operations in the Angolan Civil War.

The Mi-17 is used as a commercial passenger aircraft by Air Koryo, national airline of North Korea. Previous flights include those between Pyongyang and Kaesong and Pyongyang and Haeju.

The Mexican Navy uses its Mi-17s for anti-narcotic operations such as locating marijuana fields and dispatching marines to eradicate the plantations.[5]

The Slovak Air Force and Croatian Air Force operate Mi-17s in Kosovo as part of KFOR.

Both the pro-Gaddafi and anti-Gaddafi forces in the 2011 Libyan civil war have operated Mi-17s.

Mi-17s are operated by the Afghan Air Force. In July 2010 two Mi-17 were flown by a mixed crew of United States Air Force and Afghan Air Force personnel in a 13-hour mission that rescued 2,080 civilians from flood waters. 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.[6]

On 24 November 2015, a Russian Mi-8AMTsh was forced to land when it was hit by insurgent machine gun fire during the combat rescue mission of the ejected crew of the Russian Su-24 that was shot down by a Turkish Air Force F-16 earlier in the day. A Russian marine died in the attack, while the rest of the crew was recovered by another helicopter. The downed air-frame was destroyed with a TOW missile fired by local insurgents.

Recent orders

On 28 October 2008 the Royal Thai Army announced a deal to buy six Mi-17s to meet its requirement for a medium-lift helicopter. This is the first time the Thai armed forces have acquired Russian aircraft instead of American aircraft.[7] 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."[8]

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.[9] In August 2010, it was reported that India planned to order another 59 Mi-17s.[10] The first Mi-17V-5s entered service with India in February 2012.[11] In December 2012, India signed a contract for 71 aircraft at a reported cost of US$1.3 billion.[12] 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.[13] All 151 helicopters were delivered as of February 2016.[14]

On 11 June 2009, it was announced that the United States had handed over four Mi-17 cargo helicopters to the Pakistan Army to facilitate its counter-terrorism operations. This followed an urgent request for helicopters by Pakistan's Chief of Army Staff General Ashfaq Parvez Kayani in a leaked US embassy cable published on Wikileaks.[15]

On 10 July 2009, it was announced that Chile would pursue talks with Russia to purchase five Mi-17 multi-role helicopters for the Chilean Air Force, despite pressure from the United States.[16] However, as of January 2013, it seems that these plans were canceled.

On 16 September 2009, the United States Navy delivered the last two of four Mi-17s to the Afghan National Army Air Corps.[17] On 19 June 2010, it was announced that the US government would buy and refurbish 31 more Mi-17 helicopters from Russia to supply the Afghan Army.[18]

The US was reportedly considering adding the helicopter to the US military for Special Forces use in order to obscure troop movements.[19] The US has used some Mi-8s and Mi-17s for training,[20] and has purchased units for allies in Iraq, Afghanistan and Pakistan.[19]

In August 2010 a contract was signed by the Argentine Air Force for two Mi-17Es, plus an option on another three, to support Antarctic bases.[21][22]

In September 2010, the Polish Defense Minister announced that his country would buy five new Mi-17s from Russia, to support Polish operations in Afghanistan. All five Mi-17-1Vs were delivered by 2011.[23]

In 2010, the Kenyan Air Force purchased three Mi-171 medium-lift helicopters to supplement its fleet of IAR 330 Pumas, which have been flying for more than 20 years.

In 2011, Chief of Staff of the Afghan National Army Abdul Wahab Wardak announced that the US government will buy Mi-17s for use by Afghanistan's troops. He explained the choice of the Russian helicopter over the American Chinook was due to the familiarity of the Afghan technical and pilot staff with the helicopter type and that it is better suited for Afghanistan's environment.[24] The United States continued to purchase the helicopters for Afghanistan in 2013, despite a congressional prohibition.[25] Overall, 63 Mi-17s were acquired through the 2011 contract at a cost of US$16.4 to US$18.4 million each, or US$4 to US$6 million more each than a refurbished American Chinook.[26]

China signed two contracts with Rosobornexport in 2009 and 2012 for 32 and 52 Mi-171E, respectively.[27]

The Helicopters of Russia has concluded a contract with the Defense Ministry of Belarus for the supply of twelve Mi-8MTV-5 military transport helicopters in 2016-2017. The Belarusian military will get the helicopters possessing the same parameters as those used by the Russian military.[28]
