context_page_description: USS Thornback (SS-418), a Tench-class submarine, was the only ship of the United States Navy to be named for the thornback, a slender member of the shark family with a long pointed snout and a sharp spine at the end of each dorsal fin, native to northern Atlantic waters ranging from the temperate to the Arctic.
  Her keel was laid down on 5 April 1944 by the Portsmouth Navy Yard. She was launched on 7 July 1944 sponsored by Mrs. Peter K. Fischler, and commissioned on 13 October 1944 with Commander Ernest P. Abrahamson in command.
context_section_description: Placed in a reduced manning status on 14 April 1971, the ship was turned over to the Turkish Navy on 1 July 1971 and renamed TCG Uluçalireis (S 338) for the Ottoman admiral Uluç Ali Reis. Decommissioned from the United States Navy on that same date, she was later struck from the Naval Vessel Register on 1 August 1973. In 2000, after 28 years of service in the Turkish Navy she was taken from active duty. Handed over to the Rahmi M. Koç Museum, she can be visited at her moorings in Golden Horn in Istanbul.
