- GAO product summary, report scope and summary of 1975/1979 Navy policy
- Finding type
- gov_survey
- Finding
- GAO reviewed Navy ship asbestos use and reported that the Navy's 1975 policy replaced asbestos insulation only when damaged or removed for necessary repairs; in 1979, the policy expanded selective replacement in high-maintenance areas. This is general Navy ship-program and period context relevant to Knapp's 1943-1957 service era.

- NARA asbestos research guide, ‘Beginning Research’ and listed technical-record volumes
- Finding type
- historical_record
- Finding
- Research located no ship-specific asbestos survey, abatement record, or material specification for USS Knapp (DD-653) in the sources reviewed for this batch. The National Archives identifies ship-specific technical records, including hull and mechanical and propulsion-plant records, as research avenues for determining materials aboard a particular Navy vessel; those underlying records were not retrieved for this batch.
