JG 7 was formed under the command of Oberst Johannes Steinhoff, with Kommando Nowotny (the initial Me 262 test wing ) renumbered III./JG 7. Under the command of Major Erich Hohagen III./JG 7 was the only element of JG 7 ready to operate against the Allies. Throughout its existence JG 7 suffered from an irregular supply of new aircraft, fuel and spares.
