[2]NavSource Online, PC-814 Submarine Chaser Photo Archive page (search extract reviewed 2026-10-03; direct fetch returned HTTP 406) [other_primary]

- NavSource PC-814 page: timeline and specification block
- Finding type
- vessel_history
- Finding
- The ship-specific archive identifies PC-814 as a PC-461-class submarine chaser built by Commercial Iron Works, Portland, Oregon: laid down 11 February 1944 as yard hull 87, launched 13 May 1944, and commissioned USS PC-814 on 5 June 1945. Its specification block gives 450 tons displacement, 173 feet 8 inches length, 23-foot beam, 10-foot 10-inch draft, 20.2 knots, complement 65, and two 1,440-bhp Hooven-Owen-Rentschler R-99DA diesel engines on two shafts.

- Limitations
- The page is a private archival compilation rather than a Navy publication, and the direct live fetch returned HTTP 406; the facts above were recovered from the live search extract. The specification block is not a hull survey and does not document asbestos or materials. Builder and machinery details should be rechecked against an accessible primary record before a higher-confidence conversion.

[3]Archived Naval History and Heritage Command, 'Pacific Typhoon at Okinawa, October 1945' (Wayback capture 2025-12-08; current NHHC URL returned 404 on 2026-10-03) [other_primary]
- Locator
- Archived NHHC page narrative and vessel table: PC 814 row, 'Grounded - Beyond economical repair'
- Finding type
- vessel_history
- Finding
- NHHC's October 1945 Okinawa typhoon table lists PC 814 as grounded and beyond economical repair. The surrounding narrative states that the storm passed over Okinawa on 9 October 1945, with winds of 80 knots and 30-35-foot waves; the table places PC 814 among the craft damaged or grounded at Buckner Bay.

- Limitations
- NHHC establishes the typhoon event and disposition category, not the exact grounding time, reef position, salvage actions, crew exposure, or asbestos content. The page's storm date is 9 October while the ship archive and NARA records use 10 October for the ship's loss/decommissioning sequence; the date distinction is retained rather than silently reconciled.

[4]National Archives, Special List #44, 'by Ship Numbers' (live PDF search result verified 2026-10-03) [other_primary]
- Locator
- Special List #44, PC-814 row
- Finding type
- vessel_history
- Finding
- NARA's ship-number list records PC-814 with a commissioning date of 6/5/1945 and a decommissioning date of 11/30/1945. This corroborates the ship-specific commissioning date and establishes the recorded decommissioning date.

- NavSource PC-814 page: loss summary and Naval Register date
- Finding type

- Finding
- The ship-specific archive states that PC-814 was lost in Typhoon Louise off Okinawa on 10 October 1945 and struck from the Naval Register on 19 December 1945.

- Limitations
- The direct page fetch was blocked with HTTP 406, so this row relies on the live search extract. The archive's summary does not establish whether the hull was salvaged, dismantled, or remained as a wreck after being struck, and it does not address asbestos.

[6]GAO HRD-80-2, 'Navy Efforts To Protect Workers From Asbestos Exposure' (program-level context; page availability not independently verified in this session) [gao]
- Locator
- GAO product page HRD-80-2
- Finding type
- gov_survey
- Finding
- Program-level context: GAO's Navy asbestos review describes Navy policies concerning asbestos insulation and its removal or replacement during the 1970s. This supports the general historical context that asbestos was a Navy ship-repair concern during the service era of WWII-built vessels.

- Limitations
- GAO does not name PC-814, its builder, or its Okinawa wreck. It cannot establish asbestos aboard this hull, any product identity, any individual exposure, or any legal eligibility. The full report was not retrieved in this session; the row is context only.

- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, material specification, abatement record, hazmat disclosure, or verified exposure record was located in the sources searched. The available official records document identity, service dates, and the Okinawa grounding, but do not identify asbestos aboard PC-814.

- Limitations
- A negative search finding is not proof that asbestos was absent. The CourtListener sweep was not completed because the authenticated fleet-wide pacing limiter reported that the request budget was momentarily spent; this row therefore does not make a negative litigation finding. Firecrawl research was also unavailable because its keyless session reported a multi-hour quota wait.

[8]NavSource PC-814 specification block (search extract; direct fetch returned HTTP 406) [other_primary]

- NavSource PC-814 page: PC-461 class and propulsion specification block
- Finding type
- asbestos_application
- Finding
- Class/era context only: PC-814 was a 1944-built PC-461-class steel patrol craft with twin diesel propulsion, not a steam-powered vessel. Era-standard applications such as machinery or exhaust insulation, gaskets, packing, electrical insulation, and compartment materials are plausible pathways, but no cited source establishes that any were asbestos-containing or installed aboard this hull.

- This row is an inference from class, construction era, and the reported diesel machinery. It must not be read as proof of asbestos aboard PC-814, a product identification, or an exposure finding; no boiler or steam-line asbestos pathway is asserted.
