- Documented for this hull: laid down 5 February 1943 at Electric Boat Co., Groton, Conn.; launched 17 October 1943 (sponsor Mrs. Wreford G. Chapple); commissioned 24 January 1944, Commander Chapple in command. Six war patrols in the Java, Celebes, Sulu, and South China Seas and the Gulf of Siam; sank two Japanese vessels totaling 6,934 tons and shared with Ray (SS-271) and Guitarro (SS-363) in destroying a 6,806-ton passenger-cargo vessel; daring surface attack damaging the heavy cruiser Aoba off western Luzon 23 October 1944. Navy-yard overhaul at San Francisco from June 1945; decommissioned in reserve 31 January 1946; recommissioned 5 June 1951 for Submarine Squadron 3 type training and Fleet Sonar School services at San Diego; decommissioned 10 September 1952 at San Francisco for conversion to a killer submarine; reclassified SSK-243 18 February 1953 and recommissioned 20 June 1953; Alaskan training cruise 1954; Western Pacific cruise 1956-57; auxiliary submarine AGSS-243 15 April 1964; decommissioned 28 June 1969 at Mare Island; struck and sunk as a target 7 November 1969 by Sculpin (SSN-590).

[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 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 (5,400 hp), four General Electric main 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.

- 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 electrical/battery materials.

[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 throttled at the daily cap (HTTP 429, 'expected available in 62981 seconds'), so the sweep ran on the site:courtlistener.com index fallback for "USS Bream" and "SS-243". The fallback surfaced only general Navy asbestos litigation - 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.

- Limitations
- 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.
