6 U-boats assigned to this flotilla during its service.
The 30th Flotilla was founded in October 1942 under the command of Kptlt. Helmut Rosenbaum. The boats reached Constanza after a transport up the river Elbe, then over land to the river Danube.
The operational area was limited to the Black Sea. Its history ended in September 1944, when the three last Flotillas boats U-19, U-20 and U-23 were scuttled on 10 and 11 September, 1944 near the Turkish coast.
