Known for most of its operational life as Royal Air Force Gatow, or more commonly RAF Gatow, this former British Royal Air Force station (military airbase) is in the district of Gatow in south-western Berlin, west of the Havel river, in the borough of Spandau. It was the home for the only known operational use of flying boats in central Europe, and was later used for photographic reconnaissance missions by de Havilland Canada DHC-1 Chipmunks over East Germany. Part of the former airfield is now called General Steinhoff-Kaserne, and is home to the Luftwaffenmuseum der Bundeswehr, the German Air Force Museum.
