It was built in Philadelphia and launched in 1943.","why_significant":"The nomination calls Lionfish a significant, almost intact example of the standard fleet submarine that played an important part in World War II. It avoided the postwar 'guppying' alterations and retains its original design and fittings. Because it does not meet the age criteria, it was nominated as an exception on the grounds that it is virtually intact and serves as an educational tool.","narrative":"Lionfish is a World War II submarine of the Balao class, semi-permanently moored in Battleship Cove on the Taunton River in Fall River, Massachusetts. It measures 311 feet long and 27 feet wide, with a 16-foot-diameter pressure hull and a teakwood deck. Four diesel-electric engines delivered 6,500 horsepower, and the boat ran submerged on batteries. It was launched in Philadelphia in November 1943, fitted out at Portsmouth Naval Shipyard, and commissioned in November 1944. In 1945 it joined the Pacific Fleet, made two war patrols near Japanese waters, and is credited with sinking an I-class submarine and a 100-ton schooner. Later service included reserve status, recommissioning in 1951, Atlantic and Mediterranean operations, and training duty from 1959 to 1972, when it moved to Battleship Cove. Most wartime submarines were heavily rebuilt after the war, but Lionfish kept its original design and fittings. It was listed as an exception to the age rule because it is nearly intact and serves as an educational tool.","period_of_significance":"1943","architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"Semi-permanently moored at Battleship Cove and used as a museum and educational resource; condition listed as good.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:11:55.070562-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/78/7945/63794578/content/electronic-records/rg-079/NPS_MA/76002270.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/76002270/c96b13e772-800.webp","url_1600":"https://nationalhistoricalregister.com/media/76002270/c96b13e772-1600.webp","licence":"Public domain","author":null,"credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:USS_Lionfish_(SS-298).jpg\" rel=\"noopener\">Unknown author</a>, Public domain, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:USS_Lionfish_(SS-298).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63794578","wikipedia":"https://en.wikipedia.org/wiki/USS_Lionfish","wikidata":"https://www.wikidata.org/wiki/Q3544085"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/bristol-county/uss-lionfish-ss0298-national-historic-landmark-76002270/"}
