Royal Prussian Jagdstaffel 57, commonly abbreviated to Jasta 57, was a "hunting group" (i.e., fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I.
[1] Jasta 57 was founded at the pilots and observers training school at Königsberg on 6 January 1918.
Four days later, it was incorporated into Rudolf Berthold's Jagdgruppe Nord and tasked to support 6 Armee.
Leutnant Hans Viebig (1897–1961), who would become Oberst of the Wehrmacht with the Knight's Cross of the Iron Cross, was first and shot down a Royal Aircraft Factory R.E.8 of the Royal Flying Corps.
It moved once again on 6 June, to join Jagdgruppe 7 under Emil Thuy in support of 2 Armee.
