- Study period
- Pre-mid-1970s Navy ship construction
- Population
- Navy personnel generally; not a Harveson-specific population
- Limitations
- This is general Navy-era guidance, not a record for Harveson or the Edsall class. The timing permits only a class-or-era inference; it does not establish installation, product identity, amount, condition, disturbance, exposure, causation, or legal eligibility aboard this hull.

[3]CourtListener API v4 authenticated sweep: exact-name, hull-number, surname, and asbestos-qualified searches across opinion and RECAP indexes [court_record]
- Locator
- CourtListener v4 search endpoint, type=o and type=r; 2026-09-28 authenticated queries recorded in search_ledger rows sl-01 through sl-04
- Finding type
- litigation_documented
- Finding
- No qualifying asbestos litigation result naming USS Harveson or DE/DER-316 was located. The sole exact-name opinion result, United States v. McBride, No. 6372 (C.M.A. 1955), is an unrelated military construction-contract dispute; exact-name RECAP returned zero results. DE-316 and Harveson searches returned numeric and personal-name collisions, not vessel-asbestos litigation.
