Hill Air Force Base (AFB) is a U.S. Air Force installation situated in Davis County, Utah, near Ogden, Layton, Clearfield, Riverdale, Roy, and Sunset. Approximately 30 miles north of Salt Lake City, the base was named in honor of Major Ployer Peter Hill of the U.S. Army Air Corps, who died in 1935 during a test flight. Construction of the Ogden Air Depot began in 1939, and the facility officially opened as Hill Field on November 7, 1940. During World War II, it served as a maintenance and supply base, repairing and returning thousands of aircraft to combat. It also became a long-term storage site for surplus airplanes. Hill Field was redesignated Hill Air Force Base on February 5, 1948, following the creation of the United States Air Force. The base played a significant role in logistical support during the Korean War and later provided maintenance for jet aircraft such as the F-4 Phantom II, F-16 Fighting Falcon, A-10 Thunderbolt II, and C-130 Hercules, along with missile systems. Currently, Hill AFB is home to the Air Force Materiel Command's Ogden Air Logistics Complex (OO-ALC), which manages a range of aircraft, engines, missiles, software, avionics, and components. The host unit is the 75th Air Base Wing, responsible for base operating support. Operational units include the 388th Fighter Wing and the 419th Fighter Wing, both operating F-35A Lightning II aircraft. The base also houses the Hill Aerospace Museum, which features over 80 retired aircraft and missiles, and manages the Utah Test and Training Range, a live-fire training area.
