- Finding
- Documented for this hull: laid down 15 December 1942 by Cramp Shipbuilding Corp., Philadelphia; launched 7 November 1943 (sponsor Mrs. Harold C. Train); commissioned 1 November 1944, Lt. Comdr. Edward D. Spruance in command. Two Pacific war patrols in 1945 (Bungo Suido, Yellow Sea, lifeguard duty off Shanghai and the Nansei Shotos; embarked rescued B-29 survivors via Ray). Arrived Mare Island Navy Yard 11 September 1945 and decommissioned 16 January 1946 per DANFS (NavSource gives 16 December 1946 - conflict in gaps). Recommissioned 31 January 1951 (Lt. Comdr. Arthur G. McIntyre); Sonar School training ship; New London home port; Mediterranean cruise October-December 1952; decommissioned 15 December 1953 at New London into the Atlantic Reserve Fleet. Placed in service in reserve 1 March 1960 as Naval Reserve training submarine at Providence, R.I. One battle star.

[2]NavSource Online Submarine Photo Archive, 'as built to the specifications' block for this hull; corroborated by BuShips Ships' Data 1945 submarine machinery tables (via shipscribe.com, per class profile) and DANFS spec block (diesel-electric, 20.25 kt surfaced) [other_primary]

- Finding
- Machinery fit for this hull per NavSource 'as built to the specifications' block and class-profile navypedia block map: diesel-electric reduction gear drive - four Fairbanks-Morse main generator diesel engines (5,400 hp), four Elliot Motor Co. main motors (2,740 hp), two 126-cell main storage batteries, two 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 'as built' 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.

[3]NPS National Register of Historic Places Inventory-Nomination Form 10-300, USS Lionfish, refnum 76002270 (nominated June-July 1976; entered 30 September 1976) [nps]

- historical_record
- Finding
- NPS National Register nomination (refnum 76002270, entered 30 September 1976) documents this hull's material condition: condition checked 'UNALTERED' and 'MOVED'; 'The ship escaped the guppying process (the complete exterior and interior alteration that most World War II submarines experienced after the war) and retains its original design and fittings'; 'a significant, almost intact example of the standard fleet type submarine... virtually intact.' Nomination also records she was fitted out at the Portsmouth Naval Shipyard after launching at Cramp - a ship-specific yard-attribution fact.

- Ship-specific material-condition record - but it contains NO asbestos or hazardous-material characterization; 'virtually intact' describes fabric survival, not fiber content. The nomination's 76-crew figure conflicts with the DANFS spec block (66) - variant in gaps.

[4]Balao class profile ev-balao-class-05 (era/design inference for diesel-electric fleet boats) built on navypedia and BuShips Ships' Data 1945; GAO HRD-80-2 for the Navy's era asbestos-use regime [other_primary]

- Finding type
- asbestos_application
- Finding
- Class/era inference for diesel-electric fleet boats of this build period: era-standard applications likely included asbestos-containing diesel exhaust lagging, engine gaskets and packing, hull thermal and acoustic insulation, insulation around galley/refrigeration equipment, and battery/electrical materials. The NPS-documented unaltered/'virtually intact' condition of this preserved hull is consistent with retained original-era material, but no survey confirms or denies remaining ACM aboard.

- CLASS/ERA INFERENCE ONLY - no ship-specific material schedule, insulation survey, or asbestos product list was located for this hull, and no litigation record names her. Names era-standard applications, not confirmed installed materials; no quantity. Does not establish exposure or eligibility for any individual.

- Locator
- gao.gov/products/hrd-80-2
- Finding type
- gov_survey
- Finding
- GAO-documented Navy asbestos-management regime for the period covering this hull's postwar service/reserve: standing policy (1975) removed asbestos insulation only when damaged or as 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 availability disturbed it.

[6]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]

- litigation_documented
- Finding
- Litigation sweep for this hull: exact-name opinion/docket and hull-number queries were throttled (HTTP 429) before completion. The site:courtlistener.com fallback sweep surfaced only name collisions (Lionfish Music LLC; a Florida nightclub entity). 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 sustained API throttling (HTTP 429) during this sweep left some queries incomplete - completed and blocked queries are itemized in search_ledger. Site:-index fallback is corroboration, not a substitute for docket search. Does not prove no litigation exists.

- No hull ACM survey, abatement contract, scrapping/disposal hazmat disclosure, or adjudicated exposure finding naming this vessel was located anywhere in the research sweep.

- Builder-completion context documented for this hull: Cramp Shipbuilding's wartime submarine program ran late and troubled - the Navy had Cramp boats completed/fitted out at Navy yards. The NPS nomination states Lionfish 'was fitted out at the Portsmouth Naval Shipyard in New Hampshire' after launching at Cramp - a documented second-yard construction period for this hull.
