The TCG Hızır Reis is a submarine notable for its high performance and striking offensive capabilities after World War II. Originally serving in the United States Navy as USS Gudgeon, the submarine spent 30 years in the U.S. Navy and was a key vessel during the Cold War. In 1983, it was transferred to the Turkish Navy and raised the Turkish flag in California. On September 30, 1983, it officially entered the Turkish Navy inventory as TCG Hızır Reis.
