Air warfare branch of the German Empire
The Deutsche Luftstreitkräfte —known before October 1916 as Fliegertruppen —was the air arm of the Imperial German Army. In English-language sources it is usually referred to as the Imperial German Air Service, although that is not a literal translation of either name. German naval aviators of the Marine-Fliegerabteilung were an integral part of the Imperial German Navy. Both military branches operated aeroplanes, observation balloons and airships.
