In May 1937 the unit moved to Neustadt and was redesignated as the Unterseebootsschulflottille, ("U-boat School Flotilla"), commanded by Kapitänleutnant Heinz Beduhn.

In June 1940 it was redesignated 21. Unterseebootsflottille, and in July 1941 the flotilla moved bases to Pillau. The flotilla was disbanded in March 1945.^[1]
