Air force bases are military installations used by the Air Force to support operations, training, and maintenance of aircraft. These bases typically include runways, hangars, and facilities for personnel. They serve as hubs for various missions, including air defense, reconnaissance, and humanitarian assistance. In addition to housing aircraft, air force bases often provide living quarters, dining facilities, and recreational areas for service members and their families. They play a crucial role in national security by ensuring that air forces are ready to respond to threats and support missions both domestically and internationally.
