- DANFS record for this hull: namesake Ensign John Joseph Brennan (killed 3 April 1942 as armed-guard officer aboard SS Otho); launched 22 August 1942 by Mare Island Navy Yard as HMS Bentinck (BDE-13); completed for American use and reclassified DE-13 (25 January 1943 per DANFS text; renamed Brennan 6 January 1943 per secondary sources); commissioned as Brennan 20 January 1943, Lt. Comdr. H. A. Adams Jr. in temporary command, Lt. Comdr. M. E. Dennett assuming permanent command 21 January 1943; from 1 March 1943 until October 1945 operated in the Miami Straits and Caribbean as a training ship for prospective officers and nucleus crews of destroyer escorts under construction; decommissioned 9 October 1945; scrapped 12 July 1946. Specs block: displacement 1,140; length 289'5"; beam 35'1"; draft 10'6"; speed 21 kt; complement 156; armament 3x3-in; class Evarts.

- Limitations
- DANFS documents service history and specifications, not materials or asbestos content. The transcription does not state the laid-down date, the decommissioning location, or the stricken date (24 October 1945, from secondary sources - carried in gaps). Mirror transcription cited because the live NHHC page returns 404; canonical NHHC URL remains unlocated (standing NHHC link-rot noted in BATCH-01-REPORT).

- Secondary transcription of official-era data (HyperWar/ibiblio compilation); establishes the diesel-electric plant (no steam boilers aboard this class), which bounds the era-inference product list. Contains no asbestos information. Complement here (198) is the class design figure and conflicts with DANFS's 156 - DANFS is carried; conflict noted in gaps.

- Finding type
- asbestos_application
- Finding
- Era/class inference: the contemporaneous 1946 industrial-hygiene survey documents that asbestos-containing pipe covering and insulation were standard in U.S. naval vessel construction during WWII, including shipboard installation work. As a 1942-43 Mare Island-built destroyer escort, Brennan was constructed in the same program and period. For this diesel-electric class (4 GM 16-278A engines, electric drive - no steam boilers), era-consistent asbestos applications are diesel exhaust and muffler lagging, engine-room thermal/acoustic insulation, machinery gaskets and packing, electrical cable insulation, bulkhead/fire insulation, deck coverings, and galley/accommodation insulation - not boiler or steam-drum insulation.

- Population
- WWII naval vessel construction trades (pipe coverers and insulators); era crews (class context)
- Limitations
- Class/era inference only - the study surveyed pipe-covering operations across anonymized yards and does not name this hull, this class, or Mare Island specifically; the 2026 critique documents the study's existence, content, and flaws but is a secondary source for the original. Asbestos presence aboard this specific hull is inferred from era practice, not ship-proven; does not establish quantity, condition, or any individual exposure.

- Finding
- Builder-yard context: the Atlas yard dataset documents asbestos-containing products at Mare Island Naval Shipyard (Unibestos, Marinite, Transite, Kaylo, Careytemp, packing, gaskets, bonnet insulation, refractories) and a verified appellate record of a Mare Island welder's mesothelioma (Collins v. Plant Insulation Co., 2010). Brennan was built at Mare Island in 1942-43.

- Population
- Mare Island Naval Shipyard workers (yard-level, various periods)
- Limitations
- Yard-level documentation, not hull-level: the Collins exposure period (1976-1994 at Mare Island) postdates Brennan's construction by three decades, and the EIS/EIR documents buildings ashore, not vessel materials. Establishes that the builder yard used asbestos products; does not establish asbestos content of this hull. Citation URL is a case-text mirror of the appellate opinion per the yard dataset's own citation.

- Litigation sweep: exact-name CourtListener searches returned zero results - "USS Brennan" (type=o, opinion full text): 0 hits; "USS Brennan" (type=r, RECAP docket index): 0 hits. No qualifying asbestos litigation naming this hull was located in CourtListener indexes. Supplemental queries (hull-number and partial-name variants) were deferred when the shared fleet pacing budget was exhausted; exact-name coverage on both indexes is complete.

A zero result does not prove no claim was ever filed - it means no indexed opinion or docket names this hull. Law-firm marketing pages list this hull on standard target rosters but are not evidence of any docketed case.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, building specification, or docketed case naming USS Brennan (DE-13) was found in the public sources searched (see search_ledger). The hull was scrapped in 1946, so no museum-era survey or extant-material record can exist.

Does not establish or defeat any claim of exposure or legal eligibility. Ship-specific asbestos documentation status: unknown.
