The Deutsche Luftstreitkräfte (German: [ˈdɔʏtʃə ˈlʊftˌʃtʁaɪtkʁɛftə], German Air Force)—known before October 1916 as the Fliegertruppen des deutschen Kaiserreiches (Imperial German Flying Corps) or simply Die Fliegertruppe—was the World War I (1914–18) air arm of the German Army, of which it remained an integral part. 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 serving with the Marine-Fliegerabteilung remained an integral part of the Imperial German Navy (Kaiserliche Marine). Both military branches, the army and navy, operated conventional aircraft, balloons and Zeppelins.
The first military aircraft to be acquired by the German Army entered service in 1910 – forming the nucleus of what was to become the Luftstreitkräfte in October 1916. The duties of such aircraft were initially intended to be reconnaissance and artillery spotting in support of armies on the ground, just as balloons had been used during the Franco-Prussian War of 1870–1871 and even as far back as the Napoleonic Wars. For comparison, France's embryonic army air service (Aviation Militaire), which eventually became the Armée de l'Air, was instituted later in 1910 – the Air Battalion of the Royal Engineers (later re-organised as the Royal Flying Corps) was not formed until November 1911.
Luftstreitkräfte is a German word which literally means air force. In particular it may refer to:
