- Finding
- Documented for this hull: launched 20 October 1941 by Portsmouth Navy Yard (sponsor Mrs. William H. Allen); commissioned 14 March 1942, Lt. Cmdr. Arthur H. Taylor in command. Thirteen war patrols - the first submarine to patrol with the new SJ-type surface radar - across the Bonins-East China Sea, Yellow Sea, south of Japan, Palau/Saipan, Truk, and the Cape Engano scouting line (with Halibut and Tuna) during the Battle for Leyte Gulf; plus lifeguard duty near Tokyo on her 12th-13th patrols. All but the 12th designated successful; Presidential Unit Citation for the second, fifth, sixth, and seventh patrols; 11 battle stars. Postwar: reserve in commission 20 April 1946, decommissioned 12 February 1947; reserve training ship for the 6th Naval District from August 1948; out of service May 1952; again reserve training at Portsmouth, N.H. from June 1956; struck and sold for scrap to Jacob Checkoway 23 August 1960.

[2]NavSource Online Submarine Photo Archive, header 'as built' spec block and disposition line 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]

- Finding
- Machinery fit for this hull per NavSource 'as built' spec block: diesel electric reduction gear with four Fairbanks-Morse diesel engines (5,400 hp), four Elliot Motor Co. electric motors (2,740 hp), 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).

- 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, expected available in ~3.7 hours), so the sweep ran on the site:courtlistener.com index fallback for "USS Haddock" and "SS-231". The fallback sweep surfaced only general Navy/submarine asbestos litigation - nothing naming this hull. Name-collision caveat: USS Haddock SSN-621 (Permit class) served 1967-1993; postwar references are presumptively the later boat. 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.

[5]Negative finding: no qualifying non-litigation ship-specific asbestos record located across DANFS/NHHC (via hazegray/losthistory transcription and Wayback captures), NavSource, and ACM-survey/abatement/disposal sweeps [other_primary]

- Finding type

- 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 custody and was sold for scrap in the pre-OSHA/pre-NEPA era; no hazmat or material-condition documentation of any kind was located for the scrapping or reserve 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.

- Finding
- Postwar custody and terminal disposition for this hull: decommissioned 12 February 1947 at New London; placed in service August 1948 as a Naval Reserve Training Vessel in the 6th Naval District; out of service May 1952 and laid up in the Atlantic Reserve Fleet, New London; again in service June 1956 as a Naval Reserve Training Vessel at Portsmouth, N.H.; placed out of service and struck 1 June 1960 (NavSource; DANFS gives 'struck... and sold for scrap to Jacob Checkoway 23 August 1960' - carried as struck 1 June, sold 23 August). Two separate reserve-training custody phases on era material, ended by a scrap sale with no located hazmat documentation.

[7]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]
- Locator
- GAO product page HRD-80-2 (full text blocked, HTTP 403)
- Finding type
- gov_survey
- Finding
- GAO-documented Navy asbestos-management regime for the period covering this hull's postwar custody (reserve-training custody 1947-1960): GAO found the Navy's standing policy (1975) removed asbestos insulation only when damaged or required for repairs, modified 1979 to selective replacement in high-maintenance areas - meaning original-era insulation typically remained in place for decades unless a yard period disturbed it.
