history
Initially, the boat was primarily used to clear mines laid in the First World War and otherwise provided routine service in German waters. When the Kriegsmarine began rapidly building a submarine weapon after the German-British naval agreement of 1935 , the M 113 was converted into a submarine tender and put into service as such on June 20, 1936 with the new name Acheron . The boat served from October 8, 1936 at the test command for new warships and the test committee for submarines. The submarine acceptance groups (UAG) I, III and V of the “submarine acceptance commission” were stationed on the Acheron in Danzig .
On October 1, 1940, the boat was renamed M 513 and then used for the remainder of the war in mine detection and security. After the war it became the spoils of American war. It was scrapped in 1946 at the Pollock and Brown shipyard in Southampton , England.
