Erprobungskommando 154 was formed in November 1943 in Langenhagen, to test the new Focke-Wulf Ta 154 night fighter.
The use of the term in the World War II era Luftwaffe was for special units used to test new aircraft for combat readiness (as Erprobungskommando units) and examples existed that only used the "Kommando" name, such as the Luftwaffe Gruppe-sized Kommando Nowotny.
In September Hauptmann Eder was transferred to Erprobungskommando 262 and appointed Staffelkapitän, 1./Kommando Nowotny.
Major Wolfgang Späte, of JG 54 was transferred into the experimental flying unit Erprobungskommando 16 at Bad Zwischenahn in Northern Germany, where the Messerschmitt Me 163 Komet was under development and tactical testing.
