- Finding
- The DANFS entry identifies PC-810 as a 173-foot submarine chaser laid down at Portland, Oregon, on 30 October 1943 by Commercial Iron Works; launched 11 December 1943; and commissioned 3 April 1945. Its specification block gives displacement 280 tons, length 173 feet 8 inches, beam 23 feet, draft 10 feet 10 inches, speed 18 knots, complement 65, one 3-inch/50 gun, and PC-461 class.

- Commercial Iron Works construction trades (1943-45); U.S. Navy crew (1945-46)
- Limitations
- Ship-specific naval history and specifications only; the DANFS entry does not identify asbestos, materials, work packages, abatement, individual exposure, or remaining equipment. The page is a transcription mirror because the live NHHC URL tested on 2026-10-03 returned 404.

[4]Naval Vessel Register, official inventory notice [other_primary]

- NVR official inventory notice, statement on pre-1987 disposals; live site accessed 2026-10-03
- Finding type
- historical_record
- Finding
- The live NVR site states that ships and service craft disposed of before 1987 are currently not included, although data is gradually being added. PC-810 was stricken in 1946 and transferred to Korea in 1950 according to DANFS; no hull-specific NVR detail page was located in the live inventory during this sweep.

- Limitations
- This is an archival-coverage limitation, not proof that no historical NVR record ever existed and not a finding about asbestos or material condition. The NVR site does not supply a PC-810-specific entry here.

[5]Authoritative-source research boundary: no ship-specific asbestos survey, abatement record, material specification, or asbestos application record located for PC-810; class/era context retained only as non-hull-specific context. [other_primary]
- Locator
- Research ledger entries for DANFS, NVR, and CourtListener; see search_ledger
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos documentation was located. PC-810 was a PC-461-class submarine chaser built in 1943-45, but neither the class designation nor wartime construction era establishes that asbestos was installed aboard this hull. No asbestos product is normalized as documented.

- Population
- PC-810 crew and Commercial Iron Works trades; no exposure population established
- Limitations
- Negative research finding, not proof of absence. Firecrawl live-web research was unavailable because its keyless MCP quota reported an approximately 18-hour reset; direct authoritative-page fallback was used. No inference from class, propulsion, construction era, or generic shipbuilding practice is promoted to a ship-specific finding.

[6]CourtListener authenticated helper sweep: four required base queries were attempted once each; the fleet-wide pacing limiter was spent before any result page was returned. [court_record]

- Finding type
- historical_record
- Finding
- CourtListener results are unknown, not no-result: the required searches for exact name (opinion and docket) and hull number (opinion and docket) could not return result pages because the authenticated fleet limiter reported its pacing budget spent. No asbestos-qualified variants were run because no base query returned an overflow page.
