She is berthed at Pier 45, Fisherman's Wharf, San Francisco, as a museum ship.","why_significant":"The nomination presents Pampanito as representative of the U.S. submarine force that blockaded Japan in World War II. She made six war patrols, is credited with sinking five ships (27,288 tons), and took part in rescuing 73 Allied POWs. She was serviced at Mare Island and retains her wartime integrity, having escaped postwar modernization.","narrative":"Berthed at Pier 45 on San Francisco's Fisherman's Wharf, USS Pampanito is a Balao-class fleet submarine built at the Portsmouth Naval Shipyard in New Hampshire and commissioned in November 1943. She is 312 feet long, powered by four diesel engines, and carried ten torpedo tubes and a crew of 75. Unlike most wartime submarines, she avoided the postwar guppy conversion and keeps her original design and fittings, and she is now a museum ship in excellent condition. Her importance lies in what she represents: the American submarine campaign that cut off Japan's oil, ore and food. Pampanito completed six war patrols, earned six battle stars, and is credited with sinking five enemy ships totaling 27,288 tons. On one patrol she helped rescue 73 Australian and British prisoners of war from Japanese transports that had been sunk. She was also serviced and decommissioned at Mare Island in 1945.","period_of_significance":"1943-1945","architect_builder":"Portsmouth Naval Shipyard","architectural_style":"Balao-class fleet type submarine","criteria":[],"status_note":"Excellent condition, unaltered, and open to the public as a museum ship at Pier 45.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:55:31.376116-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_CA/86000089_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86000089/d85792b408-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86000089/d85792b408-1600.webp","licence":"CC BY-SA 3.0","author":"Sanfranman59","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pampanito_(submarine,_San_Francisco).JPG\" rel=\"noopener\">Sanfranman59</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pampanito_(submarine,_San_Francisco).JPG"},"district":{"nrhp_refnum":"06000372","name":"Port of San Francisco Embarcadero Historic District","url":"https://nationalhistoricalregister.com/districts/california/port-of-san-francisco-embarcadero-historic-district-06000372/"},"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/123858068","wikipedia":"https://en.wikipedia.org/wiki/USS_Pampanito","wikidata":"https://www.wikidata.org/wiki/Q2548504"},"indexable":true,"url":"https://nationalhistoricalregister.com/california/san-francisco/uss-pampanito-submarine-86000089/"}
