Offutt Air Force Base — Omaha, United States

Offutt Air Force Base, coded OFF, is a major United States Air Force installation located just south of Omaha, Nebraska. Historically significant as the headquarters of Strategic Air Command during the Cold War, Offutt now hosts U.S. Strategic Command, overseeing nuclear deterrence and global strike operations for the United States military. The base has a long aviation history dating back to World War I and has been the launch site for numerous reconnaissance and command aircraft, including the E-4B 'Doomsday Plane.' Offutt is not a civilian airport and does not accommodate commercial passenger traffic. Severe flooding in 2019 caused significant damage to portions of the base, prompting major reconstruction efforts. OFF remains one of the most strategically important military airfields in the country.
