- Finding type
- gov_survey
- Finding
- GAO's 1979 review states that it examined asbestos use in Navy ships and the cost of removing asbestos at Long Beach and Norfolk Naval Shipyards. It reports that the Navy's 1975 policy removed and replaced with nonasbestos materials only insulation damaged or removed for necessary repairs, and that the policy was modified in 1979 to selectively replace asbestos insulation in high-maintenance areas.

[6]Batch-5959 source review: NavSource LSM-156 hull page; NARA RG 181 finding aid; GAO HRD-80-2; search ledger [other_primary]

- Search-ledger rows sl-uss-lsm-156-lsm156-01 through -09
- Finding type
- historical_record
- Finding
- The completed public-source review located no ship-specific asbestos survey, product inventory, abatement record, material specification, or hazmat disclosure for LSM-156. The NavSource hull page, NARA finding aid, and GAO program review document vessel history, an archival lead, and era context respectively, but none identifies asbestos aboard this hull.

- Limitations
- A negative public-source finding is not proof that asbestos was absent. Undigitized commissioning files, Bureau of Ships specifications, shipyard records, disposal records, and litigation outside the incomplete CourtListener sweep may contain additional evidence; no asbestos product is therefore normalized or asserted.

[7]CourtListener API v4 via /Users/charlesfletcher/devin-prompts/cl-auth-search.py (authenticated, fleet-paced) [court_record]

- Search-ledger rows sl-uss-lsm-156-lsm156-05 through -08; saved helper outputs cl-lsm156-*.json/.err
- Finding type
- litigation_documented
- Finding
- The required authenticated CourtListener API v4 sweep was attempted for exact name and hull number in both opinion and docket searches through cl-auth-search.py. The exact-name opinion request was stopped by the fleet-wide pacing limiter; the unquoted exact-name docket request returned 196 broad results and was not treated as a ship-specific hit; the hull-number opinion request returned 13 broad results requiring collision review; and the hull-number docket request was still waiting on the fleet limiter when the research pass stopped. No qualifying asbestos-litigation finding is asserted from these broad or blocked results.

- Limitations
- This is an incomplete litigation sweep, not a clean negative. Broad results were not classified as vessel hits, and blocked requests remain unresolved. No anonymous request, raw API request, v3 API, or retry loop was used; no litigation stage, exposure, causation, or legal eligibility is inferred.
