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, and Kevlar armor 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.
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 the Mi-171, Mi-17V-5, and Mi-17V7.
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.
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.

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. 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."
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.

In 2011, Chief of Staff of the Afghan National ArmyAbdul 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. The United States continued to purchase the helicopters for Afghanistan in 2013, despite a congressional prohibition. 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.
