The HH-1N Iroquois is used by the Marine Corps to provide all-weather, day-or-night, airborne command, control and coordination for assault support operations. Additionally, it is used for assault transport and maritime special operations, forward air control, aeromedical evacuation of casualties from the field and tactical recovery of aircraft and personnel missions.
The H-1 family of helicopters, popularly known as the Huey, is the most successful military helicopter ever produced - more than 16,000 have been produced since 1956. Originating from a 1955 U.S. Army contract for a medical evacuation helicopter, the first Navy/Marine Corps Iroquois variant, the UH-1E, was first procured in 1964. Deliveries of the current version, the HH/UH-1N, began in 1971. The last, and newest, UH-1N was delivered in January 1979. Both the Navy HH-1N fleet and the Marine Corps UH-1N fleet are scheduled to start being replaced by the UH-1Y in March 2008. The UH-1N could be in the fleet until 2014 when the last UH-1Y is delivered.
