27), commonly abbreviated to Jasta 27, was a "hunting group" (fighter squadron) of the Luftstreitkräfte, the air arm of the Imperial German Army during World War I.
Armee-Flug-Park 4 (Army Flight Park 4) at Ghent contributed three aircraft and pilots to the foundation.
The newly appointed Staffelfuhrer (Squadron commander), Hans von Keudell, brought his own plane to the new unit, for the eighth aircraft.
[2] On 15 February 1917, Keudell led two of his pilots into combat in a three plane element of Albatros D.IIIs.
[2] The new squadron languished under its new commander; in three months, they suffered three casualties without scoring a further victory.
[5] Up until the end of the fighting in November 1918 Jasta 27 collectively accounted for 128 enemy aircraft and six observation balloons, and suffered eleven killed in action, three killed in flying accidents, and one taken prisoner of war.
