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 2021 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.

On 13 April 2022, US President Joe Biden announced that the US Government would supply 11 Mi-17 helicopters to the Ukrainian government to aid in its defence during the Russian invasion of Ukraine.[66] The U.S. supplied 16 Mi-17s including five that were undergoing maintenance in Ukraine when Russia invaded. These helicopters belonged to the former Afghan government, but were paid for by the US under the Afghanistan Security Forces Fund. Therefore, the Pentagon treated these aircraft as its property after that government fell in September 2021.[67]

More than 12,000 Mi-8/17 helicopters have been produced to date – a record for twin-engine helicopters anywhere in the world.
