Jagdstaffel 40

Royal Saxon Jagdstaffel 40, commonly abbreviated to Jasta 40, was a "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I. The unit would score over 54 aerial victories during the war, including three observation balloons downed. The squadron's victories came at the expense of five killed in action, one killed in a flying accident, and six wounded in action.
