The squadron would score over 20 aerial victories during the war, including four observation balloons downed. The unit's victories came at the expense of three pilots killed, and one injured in a flying accidents.
Jasta 54 was created on 1 January 1918 at Flieger-Abteilung ("Flier Detachment") 6, Großenhain, Kingdom of Saxony. It went operational on 15 January. On the 19th, the new squadron joined Jagdgruppe 10 as part of 2 Armee. On 17 March 1918, Jasta 54 scored its first aerial victories. It moved to support 4 Armee in late March. On 6 June 1918, it returned to 2 Armee even as the squadron joined Jagdgruppe 9. On 10 July, it shifted to support 3 Armee. In August 1918, JG 9 transferred to 18 Armee, whence Jasta 54 served through war's end.
