history
The boat was used in the mine search and security service in the First World War . After the end of the war it was taken over by the Reichsmarine. The Navy had the boat rebuilt in 1937, and from October 1, 1937, it was used as a so-called test boat for the test association of the communications test command (NVK) to test radio, radio measurement and fire control technology. On October 12, 1937, it was named Störtebeker . On October 1, 1940, like all boats in its class , it was given a new number and now operated as the M 566 .
After the sinking of the M 538 on June 21, 1944 during a Soviet air raid in Reval , the M 566 took over the function of the command and escort ship for the 1st clearing boat flotilla . With this it took part in the last months of the war in the evacuation of refugees and soldiers from the Kurland basin and the former German eastern regions (" Company Hannibal ").
At the end of the war, the boat was American spoils of war, but was then assigned to the German mine clearance service with the entire 1st clearing boat flotilla on July 27, 1945 . There it served until November 30, 1947 as a guide and escort ship of the flotilla, which cleared mines in the western Baltic Sea with its home port Kiel . On December 1, 1947, the boat was finally handed over to the Office of Military Government for Germany (US) (OMGUS) as US property . The OMGUS chartered it on June 18, 1948 to the "Ostdeutsche Dampfschiffs- und Transport Gesellschaft (DSTG)" in Hamburg. The boat returned to OMGUS on September 12, 1949 and was scrapped in 1950.
