- vessel_history
- Finding
- The live hull page identifies this vessel as PC-1569 / Anacortes and records: laid down 26 September 1944 at Leathem D. Smith Shipbuilding Co., Sturgeon Bay, Wisconsin; launched 9 December 1944; commissioned USS PC-1569 on 14 March 1945 at New Orleans; decommissioned 9 August 1946 at Astoria, Oregon and laid up in the Pacific Reserve Fleet, Columbia River Group, Astoria; named Anacortes 15 February 1956; struck from the Navy Register 1 June 1960; transferred to the South Vietnamese Navy at Seattle on 23 November 1960 and renamed RVNS Van Don (HQ 06); fate unknown. The page gives 295 tons light / 450 tons full load, 173 feet 8 inches length, 23-foot beam, 10-foot 10-inch draft, 20.2 knots, complement 65, and two General Motors 16-278A diesel engines on two shafts.

- Limitations
- NavSource is a photographic-archive compilation rather than a Navy registry or materials survey. It documents identity, milestones, specifications, and disposition history, but does not establish asbestos content, remaining material, individual exposure, or legal eligibility.

- NARA NAID 77593485 catalog record; 7 October 1945 cross-reference noted in PC-1547 war-diary research
- Finding type
- historical_record
- Finding
- NARA catalogs a ship-specific USS PC-1569 war-diary file unit for October 1945, providing a primary-record lead for the vessel's postwar Pacific operations. A contemporaneous cross-reference in the related PC-1547 research records PC-1569 being relieved on 7 October 1945 during air-sea-rescue patrol duty off Guam.

- Population
- PC-1569 crew and Pacific patrol personnel
- Limitations
- The NARA catalog record establishes the file unit, not asbestos conditions. The cross-reference documents an operational event but says nothing about materials, asbestos content, exposure, or causation; the complete file unit was not independently re-read in this batch.

[4]NavSource specifications block for Anacortes (PC-1569), including diesel propulsion and PC-461 class label [other_primary]

- NavSource class heading, propulsion, and specifications blocks
- Finding type
- asbestos_application
- Finding
- Era/design inference only: a 1944-45 steel PC-461-class submarine chaser with two General Motors 16-278A diesel engines would have had asbestos-relevant applications potentially associated with diesel exhaust and machinery insulation, gaskets, packing, electrical systems, brake linings, and deck coverings. This is not a finding that any listed product was installed aboard PC-1569.

- Population
- 1944-45 construction trades and Navy crew
- Limitations
- Class/era context cannot establish ship-specific asbestos presence, quantity, location, condition, or exposure. The diesel plant means no boiler or steam-line lagging is inferred. No hull material specification or survey was located.

[5]Batch-7779 source sweep: live NavSource hull page; NARA catalog; NHHC DANFS URL check; CourtListener helper attempt [other_primary]
- Locator
- Search ledger rows sl-uss-anacortes-pc1569-01 through sl-uss-anacortes-pc1569-08
- Finding type
- historical_record
- Finding
- No ship-specific asbestos record was located for USS Anacortes (PC-1569): no hull asbestos survey, abatement contract, regulatory hazmat disclosure, product-identification record, or qualifying asbestos litigation was confirmed in the sources searched. Ship-specific asbestos documentation is therefore unknown.

- Limitations
- A negative public-source search does not prove that asbestos was absent aboard the vessel and does not defeat any exposure claim. CourtListener review was curtailed after the authenticated helper returned a 3,079-second 429 backoff on the first mandated query; the remaining three base queries were not sent. NHHC's live DANFS URL returned 404 and the NavSource-linked Haze Gray transcription was unreachable.
