The '''Mil Mi-34''' ([[NATO reporting name]]: '''Hermit''') is a light [[helicopter]] designed by the [[Mil Moscow Helicopter Plant]] in either a two or four seat configuration for utility and training. It was first flown on 17 November 1986 and introduced at the [[Paris Air Show]] in 1987. The Mi-34 entered production in 1993, and is capable of performing aerobatic manoeuvres, including rolls and loops.

A new domestic engine version, Mil Mi-34M1 made its first hovering flight in October 2024. It uses the Russian made VK-650V [[turboshaft]] engine instead of the previous Radial engine.<ref name="Mi-34M1" />

In 2023, [[Russian Helicopters]] made the decision to restart production of the Mi-34, proposing the '''Mi-34M1''' using the newly developed [[Klimov VK-650]] light [[turboshaft]] engine.<ref>{{Cite web |date=2024-10-18 |title=Вертолёт с двигателем ВК-650В впервые поднялся в воздух » Авиация России |url=https://aviation21.ru/vertolyot-s-dvigatelem-vk-650v-vpervye-podnyalsya-v-vozdux/ |access-date=2025-12-31 |language=ru-RU}}</ref> The engine was planned to also be used on other [[Russia|Russian]] [[Helicopter|helicopters]] such as the [[Kamov Ka-226]] and [[Kazan Ansat]].<ref>{{Cite web |title=Rostec begins test of new VK-650V engine for KA-226T & Ansat-U |url=https://verticalmag.com/press-releases/rostec-has-started-testing-the-first-engine-in-russia-for-light-helicopters/ |access-date=2025-12-31 |website=Vertical Mag |language=en-US}}</ref> On 15 October 2024, hover tests of a [[prototype]] Mi-34M1 equipped with a VK-650V engine took place.

==Variants==
* '''Mi-34S'''<ref group=note>Jane's (2004–05) indicates that the Mi-34S is the base design and that prior to 1999, all marketing literature referred to the Mi-34 using the Mi-34C designation. The ''S'' or ''C'' suffixes were used to indicate the aircraft's certification by the [[Interstate Aviation Committee]]. The Russian word for ''certified'' ({{langx|ru|Сертифицированные}}) begins with the [[Cyrillic]] ''C'', which is [[Romanization of Russian|romanized]] as the letter ''S''.</ref> – four seat production model powered by a 239&nbsp;kW (325&nbsp;hp) Vedeneyev (VOKBM) [[Vedeneyev M14P|M-14V-26V]] nine-cylinder, air-cooled, radial engine mounted sideways in the fuselage, and equipped with modern avionics. A few aircraft were purchased by the Moscow police.
* '''Mi-34S2''' "Sapsan" – turbine version of the Mi-34. It will be able to accommodate up to 4 passengers and the first deliveries are planned by the end of 2011.
