Re-named and re-numbered TCG Ulucalireis (S-338), she transited the Panama Canal and underwent overhaul at Philadelphia Navy Yard until January 1972. Arriving in Turkey, she was Commissioned in a dual ceremony with TCG Orureis (S-337), (ex-Pomfret (SS-391)) on 3 May 1972.
Pursuant to the Foreign Military Sales Act, the ex-Thornback was permanently transferred (sold) to Turkey and simultaneously struck from the U. S. Naval Vessel Registry (NVR).TCG Ulucalireis served in the Turkish Navy until she was Decommissioned on 7 August 2000. Still under ownership of the Turkish Navy, the ex-Thornback was moved to moorings at the Rahmi M. Koc Museum of Transport, Communications and Industry in Istanbul, Turkey were she is currently open to the public.
Thornback received one battle star for her World War II service.

Thornback 766k Thornback (SS-418) stood out of New London, Conn., on 20 March 1945 bound, via the Panama Canal, for the Hawaiian Islands. She arrived at Pearl Harbor on 25 May and conducted training in Hawaiian waters prior to getting underway on 11 June for the western Pacific. As she stood down the Pearl Harbor channel, a formation of LCI's, running down the wrong side of the channel, forced Thornback to crowd dangerously near the extreme edge of the channel. In the process, the submarine damaged her sound dome, necessitating repairs and a two-day delay in departing.Text courtesy of DANFS.
