Royal Prussian Jagdstaffel 1 (commonly abbreviated as Jasta 1) was a fighter squadron of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I. Jasta 1 was founded on 22 August 1916, using single seat fighters drawn from First Army. It was one of the first wave of dedicated fighter squadrons founded as a result of Oswald Boelcke's espousal of massing fighter air power.[1] Leopold Reimann scored the first of its 138 aerial victories two days later.[2][3] It served on the Western Front until September 1917, transferred directly to the Italian Front to serve until March 1918, then returned to France for the rest of the war.[4]
Besides the experienced pilots transferred in from Abwehr Kommando Nord/Kampfeinsitzerstaffel B, other two-seater pilots under 1. Armee were also posted to the fledgling unit.[6]
Vfw. Paul Bona claimed six victories December 1916—May 1917. He was killed in a crash in June 1917. Oberleutnant Hans Kummetz achieved 7 claims in a year of command before being killed in combat with Camels of No. 45 Squadron RAF in Italy early in 1918.
The squadron claimed 138 victories, with 107 of those confirmed.[4]
