The III./JG 54 has its roots in Prussia. Initially I./JG 21, the members were drawn from the Jesau region in Prussia. The modified Jesau coat-of-arms (a shield with a Jesau cross with three diving aircraft on a red background, with a white outline on the shield) was adopted as the Gruppe's own.
On July 15, 1939, I./JG 21 was redesignated III./JG 54. However, the bureaucratic nature of the young Luftwaffe was such that it was over a year before records would reflect the new designation. Consequently, III./JG 54 fought in Poland and France as I./JG 21.
