[2]Naval History and Heritage Command, DANFS, 'Dauntless II (PG-61)' (official page located by live web search; direct fetch timed out during this session) [nhhc_danfs]

- DANFS entry title, opening paragraph, and specification block
- Finding type
- vessel_history
- Finding
- DANFS identifies the second Dauntless (PG-61) as the former yacht Delphine, built in 1921 by Great Lakes Engine Works at Ecorse, Michigan; acquired by the Navy on 21 January 1942; commissioned on 11 May 1942; assigned as flagship for Commander-in-Chief, United States Fleet at Washington; decommissioned on 11 May 1946; and transferred to the Maritime Commission for disposal on 10 June 1946. DANFS gives 1,950 tons displacement, 257 feet 7 inches length, 35 feet 2 inches beam, 16 feet 3 inches draft, 16-knot speed, and complement 135.

- Limitations
- Ship-specific history and specifications only; DANFS does not state that asbestos was installed aboard this hull, does not provide a material inventory, and does not document abatement or individual exposure. The official page was located in the live search index, but its full-text fetch timed out; NavSource is used for corroboration. No legal conclusion follows from this row.

- Finding type
- vessel_history
- Finding
- NavSource records this hull as the steel-hulled yacht Delphine, launched 2 April 1921; acquired by the Navy 21 January 1942; commissioned as USS Dauntless (PG-61) 11 May 1942; decommissioned 11 May 1946; struck 5 June 1946; and transferred to the Maritime Commission 10 June 1946. It lists three 250-psi Babcock and Wilcox boilers, two 3,000-ihp vertical quadruple-expansion Great Lakes Engine Works engines, and two shafts. It further reports return to civilian ownership, restoration at Bruges from 1998 to 2003, and operation from Monaco as Delphine.

- Construction trades, Navy crew, later civilian crews and restoration workers
- Limitations
- NavSource is a volunteer historical compilation and does not establish asbestos content, product identity, quantity, remaining material, or exposure. Its post-1946 ownership and current-operation statements are carried as reported history, not independently verified present-location facts. Boiler and engine data support only the separate era-context inference row.

[4]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (1979) product page; full report text not retrieved [gao]
- Locator
- GAO HRD-80-2 product page; full text access gap
- Finding type
- gov_survey
- Finding
- GAO's Navy asbestos-program review is used only as era context for the Navy's documented use of asbestos insulation and later substitution efforts; PG-61's 1921 construction and 1942-1946 Navy service fall within the historical period for which marine steam-plant asbestos use is plausible.

- Population
- Navy shipyard and shipboard workers
- Limitations
- Program-level evidence, not a record of PG-61. The product page does not identify materials aboard this hull, and the full report was not retrieved in this session. This row cannot establish that any particular insulation, gasket, packing, or other product was asbestos-containing aboard Dauntless.

[5]Batch-8545 research sweep and source review [other_primary]
- Locator
- This record's search_ledger; CourtListener helper diagnostic dated 2026-10-04
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, material schedule, product identification, or qualifying ship-specific asbestos-litigation record was located for USS Dauntless (PG-61) in the sources reviewed. The CourtListener sweep was not completed because the authenticated helper reported the fleet-wide pacing budget was momentarily spent and instructed the session to stand down.

- Role
- negative_finding
- Documentation level

- Accessed
- 2026-10-04
- Limitations
- A negative search finding is not proof that asbestos was absent. CourtListener coverage is incomplete for this batch because the helper stand-down occurred after an exact-name opinion attempt and before the required four-query sweep could be completed; no anonymous or raw API fallback was used.

[6]Era inference from the ship-specific propulsion record (DANFS/NavSource) and Navy asbestos-program context (GAO HRD-80-2) [other_primary]
- Locator
- NavSource propulsion block; DANFS specifications; GAO HRD-80-2 context
- Finding type
- asbestos_application
- Finding
- A 1921 steam yacht with three boilers, steam engines, steam piping, and machinery spaces would have required thermal insulation and sealing materials; period marine practice makes boiler insulation, pipe lagging, gaskets, and packing plausible asbestos-relevant applications. This is an era inference only, and no source located for this project confirms that those materials aboard PG-61 contained asbestos.

- Population

- Limitations
- Not ship-specific and not a product identification. The inference does not establish installation, quantity, condition, removal, present-day residue, or any person's exposure. No class profile was treated as proof of this hull's materials.
