USS Cutlass

USS Cutlass (hull numberSS-478), renamed as ROCS Hai Shih (SS-791) since 1973, is a Tench-classsubmarine 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.

Decommissioned and struck from the U.S. naval register in 1973, Cutlass was transferred to the Republic of China Navy and renamed ROCS Hai Shih (SS-791). She is expected to remain in service until at least 2026, 53 years after she entered service with the ROC Navy and 82 years after she was first launched.
