[2]U.S. Government Publishing Office, Senate hearing 96-55, Secretary of the Navy nominee material (William Graham Claytor, Jr. biography) [other_primary]
- Locator
- PDF biographical narrative for William Graham Claytor, Jr.; paragraph describing World War II commands
- Finding type
- vessel_history
- Finding
- Official government publication states that William Graham Claytor, Jr. served as commanding officer of the submarine chaser USS SC-516 in 1942-43. This corroborates the hull identity as USS SC-516, a submarine chaser; it does not provide construction milestones, material specifications, or asbestos information.

- USS SC-516 crew during the 1942-43 command period

[3]CourtListener API v4 authenticated search, query "SC-516", type=opinion, limit 20 [court_record]
- Locator
- Authenticated helper output: count=13; next=null; each returned result reviewed
- Finding type
- litigation_documented
- Finding
- The completed hull-number opinion query returned 13 results. Review found the results to be non-vessel name collisions, chiefly court docket-number strings containing SC-516; none was qualifying asbestos litigation naming USS SC-516.

- Limitations
- This is a negative result only for the completed hull-number opinion query. It does not establish that no litigation exists: exact-name opinion, exact-name docket, and hull-number docket base queries were stopped by the fleet pacing limiter before retrieval, and no asbestos variants were permitted because no base query overflowed 20 results.

[4]National Archives Catalog, planned ship-specific search for USS SC-516 / SC-516 and Bureau of Ships construction and material records [other_primary]
- Locator
- NARA Catalog front end; attempted queries SC-516 and exact phrase "SC-516"
- Finding type
- historical_record
- Finding
- NARA catalog and Bureau of Ships records are the primary-source lead for SC-516 construction, machinery, and material specifications. The catalog front end was reachable but its search API returned only the JavaScript application shell in this environment; no ship-specific record was retrieved.

- Study period

- Limitations
- Archival lead, not evidence that a particular record exists or that any material was fitted. The access failure is a research gap. It establishes nothing about asbestos, construction trades, crew exposure, products, or later disposition.
