More than 23,000 people work at the base. They include 13,000 civilians, 4,700 full-time military personnel, 3,700 contractors and 1,600 reservists.
Construction began in 1940 as World War II loomed.
The base occupies 6,698 acres at the Davis/Weber county line with more than 1,400 buildings and 13 million square feet of floor space.
Hill runs the Utah Test and Training Range 70 miles west of Salt Lake City, covering 2,675 square miles in western Utah and eastern Nevada.
Main organizations at Hill include the Ogden Air Logistics Center, host unit; the 388th Fighter Wing (active Air Force); the 419th Fighter Wing (Air Force Reserve); and the UTTR.
Hill's Ogden Air Logistics Center provides worldwide engineering and logistics for the F-16 Fighting Falcon and A-10 Thunderbolt aircraft.
