T-115 was a minesweeper of the Soviet Navy during World War II and the Cold War. She had originally been built as USS Apex (AM-142), an Admirable-class minesweeper, for the United States Navy during World War II, but never saw active service in the U.S. Navy. Upon completion she was transferred to the Soviet Union under Lend-Lease as T-115; she was never returned to the United States. The ship was eventually scrapped on 1 June 1966. Because of the Cold War, the U.S. Navy was unaware of this fate and the vessel remained on the American Naval Vessel Register until she was struck on 1 January 1983.
