USS Cutlass (SS-478), is a Tench-class submarine now in the service of the Republic of China Navy. She was the only ship of the United States Navy to be named for the cutlassfish, a long, thin fish found widely along the coasts of the United States and in the West Indies. Her keel was laid down by the Portsmouth Navy Yard on 10 July 1944. She was launched on 5 November 1944 sponsored by Mrs. R. E. Kintner, and commissioned on 17 March 1945 with Commander Herbert L. Jukes in command.
