The C-7 Caribou at Hill Air Force Base
Hill Air Force Base repaired, maintained and stored the Pratt & Whitney R-2000 engine used in the C-7. Furthermore, a Utah detachment of the United States (US) Army Reserve operated the C-7 from Salt Lake City for some time.
This C-7B transferred to the US Air Force in December 1966 from the Army’s 17th Aviation Company at Phu Cat Air Force Base (AFB), South Vietnam. In January 1967, it was assigned to the 483rd Troop Carrier Wing (Medium) of the Pacific Air Forces, headquartered at Cam Ranh Bay AB, but it remained at Phu Cat with the 537th Tactical Airlift Squadron (TAS). While with the 537th TAS, the aircraft was used to airdrop supplies to various ground units in forward areas. Hill Aerospace Museum received this C-7B in 1991. In 2005, it was repainted to match its appearance while flying with the 537th TAS in Vietnam.
