- Finding
- Documented for this hull: laid down 26 November 1941 by Manitowoc Shipbuilding Co., Manitowoc, Wisc. (sponsor Miss Katherine Mary Wolleson); launched 15 August 1942; commissioned 17 March 1943, Lt. Comdr. E. C. Hawk in command. Voyaged down the Mississippi to New Orleans in a floating drydock beginning 5 April 1943. Nine war patrols - Truk area (sank Thames Maru), South China Sea, mining off Cochin China, Halmahera, Kyushu/Shikoku/Honshu (sank Shiga Maru; covered Tokyo Bay approaches for the Saipan operation), Sea of Okhotsk action off Russian Sakhalin (sank Mikage Maru No. 20; nearly struck by one of her own circling torpedoes), Yellow Sea wolfpack with Spadefish - surviving a conning-tower hatch failure that flooded the conning tower and pump room, led into Midway by Pogy 11 February 1945 - China/Formosa coast, and a final lifeguard patrol off Truk. Modernization and overhaul at Mare Island Navy Yard late 1944. Decommissioned 11 May 1946 into the Atlantic Reserve Fleet, New London; reclassified radar picket submarine SSR-267 11 December 1951; recommissioned 15 June 1953 - Norfolk homeport, 6th Fleet Mediterranean deployments, Caribbean operations, NATO exercise Strikeback 1957. In commission in reserve at Charleston 2 February 1959; decommissioned and struck 1 April 1960; sold to Commercial Metals Co. 25 November 1960. Four battle stars.

[2]NavSource Online Submarine Photo Archive, header 'as built' spec block for this hull; corroborated by DANFS spec block (diesel-electric) and BuShips Ships' Data 1945 submarine machinery tables (via shipscribe.com, per Gato class profile) [other_primary]

- NavSource page header spec block for this hull (https://www.navsource.net/archives/08/08267.htm)
- Finding type
- historical_record
- Finding
- Machinery fit for this hull per NavSource 'as built' spec block: diesel electric reduction gear with four General Motors main generator engines, 5,400HP, fuel capacity 116,000 gal., four General Electric main motors, 2,740HP, two 126-cell main storage batteries, twin screws. NO BOILERS and no steam plant - the asbestos-relevant machinery profile differs materially from steam classes (no boiler/furnace insulation, no steam-line lagging run-outs; exposure-relevant systems are diesel exhaust lagging, engine gaskets/packing, hull thermal/acoustic insulation, and auxiliary equipment). DANFS documents a modernization and overhaul at Mare Island Navy Yard beginning September 1944, and the 1951-53 SSR-267 radar picket conversion (yard not identified in the cited sources).

- Limitations
- The NavSource spec block is a class-standard spec sheet, not a per-hull machinery survey - actual installed equipment is presumed class-typical and unverified for this specific hull. No hull-specific machinery or material list was located. Establishes propulsion type only, not fiber content.

[4]CourtListener API v4 (opinions type=o, RECAP dockets type=r) exact-name and hull-number searches; site:courtlistener.com index sweep as throttling fallback [court_record]

- Finding type
- litigation_documented
- Finding
- Litigation sweep for this hull: CourtListener API queries were already throttled at the daily cap (HTTP 429, 125/day - quota exhausted by prior same-day batch work), so the sweep ran on the site:courtlistener.com index fallback for the exact ship name and hull number. The fallback sweep surfaced only general Navy asbestos litigation and unrelated name collisions - nothing naming this hull. No qualifying asbestos litigation - and no litigation of any kind verified as naming this hull - was located.

- Limitations
- A negative result is bounded by the search mechanism: CourtListener coverage is not exhaustive for state-court pleadings, and the API throttle meant docket-text and opinion queries could not complete - the site:-index fallback is corroboration, not a substitute for docket search. Does not prove no litigation exists.

- Finding
- No hull ACM survey, abatement contract, scrapping/disposal hazmat disclosure, or adjudicated exposure finding naming this vessel was located anywhere in the research sweep. The hull went through reserve-fleet/postwar custody and was sold for scrap; no hazmat or material-condition documentation of any kind was located for the conversion, reserve, or scrapping periods.

- Absence of a located record is not proof no record exists. Does not establish that asbestos is or is not present aboard/within the hull, and does not establish or defeat any claim of exposure or legal eligibility.
