ww2dbaseU-3539 was laid down in 1944, but her construction was ultimately cancelled in late Jan 1945 as Soviet troops advanced steadily up the Vistula river. Her incomplete hull was captured by by the Soviets on 30 Mar 1945. Under Soviet supervision, she was launched in Jul 1945 as TS-9 and transferred to the Soviet Baltic Fleet as she received additional work toward her final completion. She moved to Liepaja (Russian: Libau), Latvia, and later to Tallinn, Estonia. At Estonia, an inspection done in Oct 1945 ruled that she was not ready for commissioning. In late 1945 or early 1946, she was moved to Kronstadt in Leningrad, Russia. In Mar 1947, she was renamed R-5. She was struck from the Soviet Navy list and was broken up for scrap in 1948.
