Air base

An airbase (stylised air base in American English), sometimes referred to as a military airbase, military airfield, military airport, air station, naval air station, air force station, or air force base, is an aerodrome or airport used as a military base by a military force for the operation of military aircraft. An airbase typically has some facilities similar to a civilian airport; for example, air traffic control and firefighting. Some military aerodromes have passenger facilities; for example, RAF Brize Norton in England has a terminal used by passengers for the Royal Air Force's passenger transport flights. A number of military airbases may also have a civil enclave for commercial passenger flights, e.g. Beijing Nanyuan Airport (China), Chandigarh Airport (India), Ibaraki Airport (Japan), Burlington International Airport (USA), Sheikh Ul-Alam International Airport Srinagar (India), Taipei Songshan Airport (Taiwan), Eindhoven airport (The Netherlands). Likewise, the opposite also occurs; large civilian airports may contain a smaller military airbase within their environs, such as Royal Brunei Air Force Base, Rimba (located within Brunei International Airport). Some airbases have dispersed aircraft parking, revetments, hardened aircraft shelters, or even underground hangars, to protect aircraft from enemy attack. Combat aircraft require secure protected storage of aircraft ordnance and munitions. Other facilities may also include technical buildings for servicing and support of survival equipment (including flying helmets and personal liquid oxygen), flight simulator for synthetic training, servicing facilities for all aircraft systems (airframes, propulsion, avionics, weapons systems) and associated ground support systems (including mechanical transport).
