HH-1H Iroquois

HH-1H Iroquois


The HH-1H is a light-lift Air Force helicopter used for distinguished visitor transport, and support of missile sites and ranges.


The pilot and co-pilot sit side-by-side and, depending on the mission, a flight engineer can be added to the crew.

Entrance to the passenger cargo area is through two sliding doors, one on each side of the aircraft. The sliding doors permit over-sized items to be loaded across the cabin. The HH-1H can accommodate up to 12 passengers, but that number and its cargo capacity is controlled by the amount of fuel necessary for the mission. For medical evacuation and ambulance service, litter racks are installed in the cab to serve six patients and one medical attendant.


The HH-1H, originally designed for local air base rescue, was delivered to the Air Force in the early 1970s. It is the single-engine version of the Huey helicopters first flown in 1956, then modified into more than 15 different models over the last 30 years.
