Royal Prussian Jagdstaffel 15, commonly abbreviated to Jasta 15, 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 150 aerial victories during the war, at the expense of seven killed in action, two killed in flying accidents, three wounded in action, one injured in a flying accident, and two taken prisoner of war.

[1] Three days later, it flew an interception mission against French and British bombers targeting Oberdorf's Mauser factory and destroyed three of them.

His death via wing failure in an early model Fokker Dr.1 triplane grounded the new aircraft and dampened the jasta's performance.

By summer 1918, the Jasta's aircraft markings had settled to royal blue fuselage and tail, brown rudders, and red noses extending back as far as the cockpit.
