Royal Prussian Jagdstaffel 17 was a World War I "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, which was the forerunner to the Luftwaffe. As one of the original German fighter squadrons, the unit would score 101 aerial victories (including fourteen wins over enemy observation balloons) during the war, with another 22 of the squadron's claims going unconfirmed. The jasta paid a price of ten killed in action, two lost in flying accidents, six wounded in action, and three injured in accidents.
