- Finding type
- vessel_history
- Finding
- The live NavSource vessel page identifies SC-641 as ex-PC-641 and as an SC-497-class submarine chaser. It states that Elizabeth City Ship Yards, Elizabeth City, North Carolina, laid her down 28 October 1941; she launched 12 February 1942; commissioned as USS PC-641 on 11 July 1942; was reclassified SC-641 in April 1943; struck from the Naval Register 21 January 1946; and transferred to the Maritime Commission 30 March 1948. The page gives her fate as unknown and lists a complement of 28 and two General Motors 8-268A diesel engines driving two shafts.

- The claimed DANFS page could not be retrieved live: the supplied NHHC URL returned HTTP 404 on 2026-10-03. This row preserves the indexed official-source transcription solely as corroboration and is not used for any asbestos finding. It does not state asbestos content, service activity, decommissioning, or fate.

- Finding type
- historical_record

[5]Batch 8016 research ledger: NHHC/DANFS, NavSource, NARA Catalog, and four authenticated CourtListener base-query attempts [other_primary]
- Locator
- search_ledger rows sl-01 through sl-06
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement contract, hazmat disclosure, material list, or qualifying litigation record was located in the accessible sources searched for SC-641 / PC-641. CourtListener is not a negative result: the four required authenticated base queries were attempted but each request timed out before results were returned.

- Limitations
- Absence of a located public record does not establish absence of asbestos aboard, exposure, causation, or legal eligibility. CourtListener result sets remain an open gap, and NARA deck logs were not reviewed.
