Hill Air Force Base — Ogden, United States

HIF is the code for Hill Air Force Base, a major United States Air Force installation located near Ogden, Utah, and one of the largest employers in the state. The base is home to the Ogden Air Logistics Complex, which handles depot-level maintenance and overhaul for a wide range of Air Force aircraft, along with hosting fighter squadrons and the nearby Utah Test and Training Range used for weapons testing. HIF is a military airfield rather than a commercial airport, so it does not offer passenger service to the general public. Its presence has shaped the economic development of the surrounding Ogden area for generations, with thousands of military and civilian personnel supporting its operations.
