HH-1H Iroquois
Initially designated as the UH-1A, the Iroquois served during the Vietnam War starting in 1962. The subsequent variation, the HH-1H, was designed as a search and rescue aircraft for Intercontinental Ballistic Missile (ICBM) sites and test ranges. These aircraft could seat up to twelve passengers and carry a wide variety of cargo.
In 1973, the HH-1H helicopter on display was delivered to the 1550th Aircrew Training and Test Wing at Hill Air Force Base. In 1987, the aircraft was used for local air base rescue, personnel transport and support of the Utah Test and Training Range. In 1996, after 7,449 flight hours, the helicopter was retired from service and put on display at Hill Aerospace Museum. During its time at Hill Air Force Base, this aircraft was involved in three recorded rescues of personnel, as denoted by the three, small, helicopter decals on the overhead hoist.
