Source measurement	The prototype, which was named V-8, was designed in 1958 and based on the Mil Mi-4 with a larger cabin. Powered by an AI-24 2,010 kW (2,700 shp) Soloviev turboshaft engine, the single engined V-8 prototype had its maiden flight in June 1961 and was first shown on Soviet Aviation Day parade (Tushino Air Parade) in July 1961.^[source]Mil Mi-8 · Design and development; only the objects and conditions stated in this passage Two months after the engines were completed by Isotov, the third prototype designated V-8A equipped with two 1,120 kW (1,500 shp) Isotov TV2 engines, made its first flight piloted by Nikolai Ilyushin on 2 August 1962, marking the first flight of any Soviet helicopter to fly with purpose built gas turbine engines. The aircraft completed its factory based testing in February 1963.^[source]Mil Mi-8 · Design and development; only the objects and conditions stated in this passage There are numerous variants, including the Mi-8T , which, in addition to carrying 24 troops, is armed with rockets and anti-tank guided missiles . The Mil Mi-17 export version is employed by around 20 countries; its equivalent in Russian service in the Mi-8M series. The only visible differences between the Mi-8 and Mi-17 are A) the position of the tail rotor (Mi-8 right side, Mi-17 left side), B) the shape of the exhausts (Mi-8 circular, Mi-17 oval), and C) Dust shields in front of engine air intakes for the Mi-17. Also Mi-17 has some improved armour plating for its crew. The naval Mil Mi-14 version is also derived from the Mi-8.^[source]Mil Mi-8 · Design and development; only the objects and conditions stated in this passage The Finnish Defence Forces and the Finnish Border Guard began using Mi-8s in the 1970s, with the Finnish Air Force receiving its first, serialed HS-2, on 28 May 1973, and the second, HS-1, on 31 May 1973. Six Mi-8Ts were obtained at first, followed by further two Mi-8Ts and two Mi-8Ps. Three of the helicopters were handed over to the Border Guard Wing. One of these was lost after sinking through ice during a landing in April 1982. It was soon replaced by a new Mi-8.^[source]Mil Mi-8 · Operational history / Finland; only the objects and conditions stated in this passage After their Border Guard service, the helicopters were transferred to the civil register, but shortly thereafter to the Finnish Air Force. In 1997 it was decided that all helicopters, including the remaining five Mi-8Ts and two Mi-8Ps, should be transferred to the Army Wing at Utti . All Mi-8s have now been retired. One Mi-8 is on display at the Finnish Aviation Museum in Vantaa , and one is at the Päijänne Tavastia Aviation Museum in Asikkala , near Lahti . One Mi-8T is on display in Tuulos. The two final Mi-8Ts were given to Hungary in August 2011 with all the remaining spare parts.^[source]Mil Mi-8 · Operational history / Finland; only the objects and conditions stated in this passage On another occasions Abkhaz Mi-8MTVs were shot down by Georgian forces, by SA-14 in one case and by RPG-18 in a second case, both during 1993. In the final case, Georgian Mi-8MTV carrying civilian refugees was shot down, killing 25 people. Georgian Air Force and Police currently operate about 20 Mi-8T/MTVs.^[source]Mil Mi-8 · Operational history / Georgia; only the objects and conditions stated in this passage The Indian Air Force inducted the Mi-8 in the 1970s as part of a growing rotary-wing fleet that evolved without centralised long-term planning. Acquired in the wake of geopolitical deals and stop-gap needs, the Mi-8 formed the backbone of medium-lift capability before being succeeded by the Mi-17.^[source]Mil Mi-8 · Operational history / India; only the objects and conditions stated in this passage Between April and May 1986, Mi-8s were used in large numbers to drop radiation-absorbing materials into the No. 4 reactor of Chernobyl Nuclear Power Plant after the Chernobyl disaster , and the fire was extinguished by the combined effort of helicopters dropping over 5000 metric tons of sand, lead, clay, and neutron-absorbing boron onto the burning reactor and injecting liquid nitrogen into it. Most of the helicopters were severely irradiated and abandoned in a giant junkyard, the so-called "machines cemetery" near Chernobyl, with several disappearing from the site in later years. During the initial operation, one crashed near the power plant after hitting a construction crane cable with all the crew of four being killed in the crash. It is now known that virtually none of the neutron absorbers reached the core.^[source]Mil Mi-8 · Operational history / Soviet Union; only the objects and conditions stated in this passage On 16 August 2013, the Ministry of Defense of Ukraine reported that one of its Mi-8MSB had set a world altitude record of 9,150 metres (30,020 ft) at the Kirovske military airfield on 15 August.^[source]Mil Mi-8 · Operational history / Ukraine; only the objects and conditions stated in this passage The Ukrainian Armed Forces used Mi-8MSB along with Mi-24s in operations against separatists in Eastern Ukraine during the Russo-Ukrainian War . On 29 May 2014, a Ukrainian National Guard Mi-8 was brought down by Russian separatist forces in Donbas using a MANPADS near Slavyansk with 12 personnel, including an Army general, killed and one seriously injured. On 24 June 2014, a Ukrainian National Guard Mi-8 was shot down by separatist forces again using a MANPADS near Slavyansk with nine personnel killed. Ukrainian forces used Mi-8 helicopters to resupply forces during the Siege of Mariupol at Azovstal iron and steel works and bring in additional reinforcements for the Azov Regiment . Some 16 Mi-8s were used a number of times, two of which were shot down. Russia claimed on 5 April that it shot down two Ukrainian Mi-8s that it said were being used to evacuate commanders of the Azov Regiment . In late August 2023, it was reported that a Russian defector named Maksym Kuzminov handed over a Mi-8AMTSh to the Ukrainian forces in coordination with Ukrainian Intelligence agents.^[source]Mil Mi-8 · Operational history / Ukraine; only the objects and conditions stated in this passage During combat in the winter of 1991 in the Croatian war and in the spring of 1992 in the Bosnian War , the Yugoslav People's Army used the Mi-8 fleet for the evacuation of injured personnel, transport of cargo and search and rescue for the crews of aircraft forced down. As most flights were made behind the front, the Croatian forces were able to down just one helicopter, which was hit by small arms fire near Slavonski Brod on 4 October 1991.^[source]Mil Mi-8 · Operational history / Yugoslavia; only the objects and conditions stated in this passage The North Macedonian Air Force bought two Mi-8MT helicopters in 2001 from Ukraine . They fly in the Transport Helicopter Squadron (ex 301. Transport Helicopter Squadron). One crashed, killing all 8 passengers and 3 crew members in an accident in January 2008 .^[source]Mil Mi-8 · Operational history / Yugoslavia; only the objects and conditions stated in this passage During the Kosovo War of 1998 and 1999, the Federal Yugoslav Air Force used Mi-8s for transport of personnel and material to forces in otherwise-inaccessible mountain areas. Evacuation of injured personnel also occurred during the 1999 NATO bombing of Yugoslavia , flying at low altitude to avoid detection by NATO aircraft. In 1999, Yugoslav Mi-8s shot down at least one US Army Hunter UAV with the door gunner's 7.62 mm machine gun. Two Mi-17V helicopters secretly operated by the Special Operations Unit post-1997 were also active during the Kosovar conflict. After the unit disbanded in 2003, the helicopters were transferred to Serbia and Montenegro's air force .^[source]Mil Mi-8 · Operational history / Yugoslavia; only the objects and conditions stated in this passage As of mid-2020, the Serbian Air Force , the successor of the Federal Yugoslav Air Force, operates a small amount of Mi-8T which are now being replaced by Mi-17 helicopters. There are 13 Mi-17 in the Serbian air force currently. They are in the 138th Mixed-Transport-Aviation Squadron of 204th Air Base and 119th Combined-Arms Helicopter Squadron (ex 199th regiment) of 98th Air Base .^[source]Mil Mi-8 · Operational history / Yugoslavia; only the objects and conditions stated in this passage Vietnam- On 22 November 1992 a Vietnamese Mi-8 was sent from Hanoi carrying rescue workers for Flight 474 , but it crashed near Ô Kha mountain on the same day.
