She made 7 war patrols, sank 8 Japanese ships totaling 26,985 tons, and earned 7 battle stars.

She measures 312 feet long, has a teakwood deck, and runs on a diesel-electric system with batteries for underwater travel. Today she is moored on Lake Erie in Cleveland beside the Naval Reserve Center and serves as a museum. Her wartime record includes seven war patrols, eight Japanese ships sunk totaling 26,985 tons, and seven battle stars. She is the lowest-numbered World War II submarine still preserved. Unlike other submarine memorials, she has not been modified for civilian visitors, who must climb down a hatch much as wartime crews did. Apart from her missing deck guns, she retains her wartime integrity. She was recognized as an example of the American submarine force that helped cut off Japan's oil, iron ore, food and other supplies.","period_of_significance":"1943-1945","architect_builder":"Electric Boat Company","architectural_style":null,"criteria":[],"status_note":"Described as in good condition and moored as a museum; missing her submarine deck armament but otherwise retaining World War II integrity.","vacant_flag":false,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:53:09.17669-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_OH/86000088_NHL.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/86000088/f528c163be-800.webp","url_1600":"https://nationalhistoricalregister.com/media/86000088/f528c163be-1600.webp","licence":"CC BY-SA 4.0","author":"Michael Barera","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Cleveland_August_2015_36_(USS_Cod).jpg\" rel=\"noopener\">Michael Barera</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Cleveland_August_2015_36_(USS_Cod).jpg"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71986465","wikipedia":"https://en.wikipedia.org/wiki/USS_Cod","wikidata":"https://www.wikidata.org/wiki/Q2078835"},"indexable":true,"url":"https://nationalhistoricalregister.com/ohio/cuyahoga-county/uss-cod-submarine-86000088/"}
