The Mil Mi-4 (USAF/DoD reporting name "Type 36",[1]NATO reporting name "Hound")[2] is a Soviet transporthelicopter that served in both military and civilian roles.
The Mi-4 was designed in response to the American H-19 Chickasaw and the deployment of U.S. helicopters during the Korean War. While the Mi-4 strongly resembles the H-19 Chickasaw in general layout, including the innovative engine position in front of the cockpit, it is a larger helicopter, able to lift more weight and built in larger numbers. The first model entered service in 1953. The helicopter was first displayed to the outside world in 1952 at the Soviet Aviation Day in Tushino Airfield.
One Mi-4 was built with a jettisonable rotor. It served as an experimental vehicle for future pilots' means of safety and ejection designs.[3]
Operational historyedit
The Mi-4 transport helicopter laid the groundwork of Soviet Army Aviation. It was widely used both in the armed forces and in Soviet civil aviation, and for several decades remained the main type of helicopter in the inventory of the Soviet Armed Forces and of the Civil Air Fleet. The Mi-4 went out of service with the development of the Mi-8. It is no longer used by the Russian Air Force, though it remained in service in some countries as a utility helicopter or as a military transport a while longer. Albania was thought to be the final country using the helicopter, and by 2005 all were out of service. The Mi-4 played a very important role in the Bangladesh liberation war of 1971. The Mi-4 was the workhorse of the Indian Air Force[4] covering the medium lift role at the time. A highly successful heli-borne operation, the Meghna Heli Bridge, using Mi-4s helped the Indian Army's 57 Mountain Division clear the Meghna River. The helilift of a battalion of Indian troops to the outskirts of Sylhet was the first heli-borne operation of the Indian army.
Much like the UH-1 Huey, after it was gradually phased out of military service, it was used in various domestic roles: search and rescue, firefighting, polar expeditioning, construction site cargo helicopter, commercial flights and many others.[3]
An official video of a North Korean Air Force combat flying skills competition released in 2014 shows that the Mi-4 is still in limited service in North Korea.[5]
Armed versions based on the Mi-4A. V for Vooruzhenniy (Armed). Mi-4A with additional armament. Modification of 1967 had weapons complex K-4V, included four 9М17М ATGM "Phalanga" and 96 57-mm NAR S-5M in six blocks UB-16-57U (or six 100-kg bombs or four 250-kg bombs or tanks with an incendiary substance); 185 helicopters were converted to Mi-4AV.[6]
