- Finding
- Documented for this hull: launched 4 April 1943 by Electric Boat Co., Groton (sponsor Mrs. D. E. Barbey); commissioned 4 July 1943, Commander D. C. White in command. Eight war patrols across the East China/Yellow Seas, Truk-New Ireland lanes, Palau, Mindanao/Sulu Seas, Honshu-Hokkaido lifeguard duty - including a guerrilla-supply landing mission north of Manila (November 1944) and lifeguard/bombardment duty off Honshu (July 1945, when she was damaged by a near-bomb and forced to Pearl Harbor). Decommissioned and placed in reserve at New London 8 June 1946; recommissioned 4 February 1952, homeported Key West for Caribbean work and Fleet Sonar School duties; again decommissioned and placed in reserve at New London 23 December 1953. NavSource adds: in service in reserve 12 September 1959 to 30 June 1967 as a pierside training ship at Detroit, MI. Struck and sold for scrapping 30 June 1967. Seven battle stars; credited with 18,159 tons sunk; seven of eight patrols designated successful.

- Finding
- Machinery fit for this hull per NavSource 'as built' spec block: diesel electric reduction gear with four General Motors main generator engines (5,400 hp), four General Electric main motors (2,740 hp), two 126-cell main storage batteries, twin propellers. 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 "Cero" and "SS-225". The fallback sweep surfaced only unrelated asbestos documents (W.R. Grace bankruptcy materials and other name-collision text) - 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.

[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 to reserve at New London 8 June 1946; recommissioned 4 February 1952 for Atlantic/Caribbean duty incl. Fleet Sonar School support at Key West; decommissioned to reserve again 23 December 1953; in service in reserve as a pierside training ship at Detroit, MI from 12 September 1959 to 30 June 1967; struck and sold for scrapping 30 June 1967. The 1959-67 pierside-training period is a distinct low-intensity custody phase - long static berthing 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 and pierside-training custody 1946-1967): 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.
