HH/UH-1N IroquoisService: Navy and Marine Corps
Description: Utility helicopter, primarily used for search and rescue, command and control and maritime special operations missions.
Mission: The HH-1N Iroquois helicopter is used by the Navy for shore-based search and rescue duties. The UH-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.
Background: 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.
UH-1N Iroquois are fielded in Marine Light Attack Helicopter
Squadrons, or HMLAs, along with the AH-1W
Super Cobras. Detachments from the HMLAs are deployed as part
of Marine Expeditionary Units to support ship-based amphibious exercises
