- Finding
- The Navy's 1979 response reproduced in the GAO report describes asbestos use across Navy shipboard applications, including thermal insulation for machinery, equipment, and piping; deck materials; electrical equipment and cable; and piping gaskets and packing. The report discusses Navy-wide practices and does not identify USS PC-468.

- Search ledger sl-uss-pc-468-pc468-01 through sl-uss-pc-468-pc468-07
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, hazmat declaration, or asbestos inventory for USS PC-468 was located in the official and authoritative sources searched for this record. The CourtListener searches did not return results, so litigation status is unresolved and is not counted as a negative finding.

- Limitations
- A failure to locate a public record does not establish that asbestos was absent aboard. The litigation searches were blocked by the shared fleet limiter, and no hull-specific hazardous-material survey or yard file was obtained.
