Helicopters UH-1N: The Bell UH-1 Iroquois, commonly (or officially in the USMC) known as the "Huey", was a multipurpose military helicopter, famous for its use in the Vietnam war. The Huey was developed from 1955 US Army trials with the Bell Model 204. The initial designation of HU-1 (helicopter utility) led to its nickname. It was first used by the military in 1959 and went into triservice production in 1962 as the UH-1. The last were produced in 1976 with more than 10,000 made in total, of which the majority (7,000 or so) were deployed in Vietnam. In Vietnam, 2,202 Huey pilots were killed and approximately 2,500 aircraft were lost, roughly half to combat and the rest to operational accidents. In Vietnam primary missions included general support, air assault, cargo transport, aeromedical evacuation, search and rescue, and electronic warfare. During the conflict, the craft was upgraded, notably to a larger version based on the Model 205. This version was initially designated the UH-1D and flew operationally from 1967. The Huey was phased out with the introduction of the UH-60 Black Hawk, although the Army UH-1 Residual Fleet has around 700 UH-1s that were supposed to be retained until 2015. Army support for the craft was intended to end in 2004. Modern twin-engine versions of the aircraft continue in service for the USMC. USAF Lieutenant James P. Fleming piloted a UH-1F on a 26 November 1968 mission that won him the Medal of Honor UH-1N: Cold-weather capture Rescue chopper Watch the first step Huey lift off UH-1N Huey Huey MINOT AIR FORCE BASE, N.D.
