Post war service
The Tripartite Naval Commission allocated U-3515 to the Soviet Union in November 1945. On 2 February 1946, she arrived in Libau, Latvia, as British N-class N30, after having been kept in the United Kingdom. On 13 February 1946, the Soviet Navy renamed her N-27, and a Soviet crew was assigned to the submarine on 15 February 1946. Her commander from May 1946 to November 1947 was future Soviet admiral Vladimir Konovalov. She was allocated to the 1st Submarine Division of the 1st Submarine Brigade, Baltic Fleet, and was renamed B-30 (designated as a Б – (B) large type submarine) on 9 June 1949.
Sources give conflicting information for the rest of its career. According to one, it was sent to the reserve fleet on 29 December 1955. B-30 was redesignated on 18 January 1956, as a floating submarine battery recharging station PZS-35. Redesignated as test hulk B-100 on 2 July 1958, until finally being struck from the Soviet Navy on 25 September 1959, and broken up for scrap on 30 November 1959. Another source states that as of March 1951, she was reassigned to 27th Submarine Division, 158th Submarine Brigade, and turned into a test hulk on 10 June 1955 and renamed BSh-28, before being renamed on 9 January 1957 as UTS-3, reflecting its new status as stationary training submarine. UTS-3 was struck from the navy list on 1 September 1972, and sold for scrap on 5 February 1973. There is a photograph of the UTS-3 at a scrapyard that is dated to the early 1970s.
