The 545th Test Group is an inactive group of the United States Air Force. It was organized at Hill Air Force Base, Utan as the 6545th Test Group in January 1979 to manage the Utah Test and Training Range and the development of unmanned aerial vehicles. In 1994, it transferred its flight testing mission to Ogden Air Logistics Center, and in 1996 the 388th Fighter Wing assumed its range management, and the group was inactivated.
