Jagdstaffel 42

Royal Prussian Jagdstaffel 42, commonly abbreviated to Jasta 42, 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 30 aerial victories during the war. The squadron's victories came at the expense of four killed in action, one wounded in action, and one taken prisoner of war.

History
Jasta 42 was founded in September 1917 at Flieger-Abteilung (Flier Detachment) 3, Gotha, Germany. The squadron became operational on 18 December 1917. On 17 April 1918, it was consolidated into Jagdgruppe 12, which was commanded by Heinrich Kroll.
