- Limitations
- The live hull page supports the stated construction, service, and disposition chronology. It contains no asbestos, insulation, product, exposure, or present-condition information; it does not support an asbestos finding.

- Limitations
- This specification record establishes diesel propulsion and the stated complement/accommodation figures, not insulation composition. The absence of boilers does not establish the presence or absence of asbestos in other shipboard components.

- Highlights
- Finding type
- gov_survey
- Finding
- GAO's 1979 review states that it examined Navy use of asbestos in ships at Long Beach and Norfolk Naval Shipyards; it describes the Navy's 1975 policy of replacing insulation with nonasbestos material only when damaged or removed for necessary repairs and the 1979 addition of selective replacement in high-maintenance areas.

- Limitations
- This is a post-disposal, program-level record concerning Long Beach and Norfolk, not LST-609, its builder, or its scrapping yard. It neither establishes nor disproves asbestos aboard this hull or exposure of any individual.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the accessible sources searched: no asbestos survey, abatement contract, hazardous-material disclosure, insulation drawing, material schedule, or authoritative museum/registry record naming USS LST-609 was found.

- Limitations
- This access- and coverage-limited negative finding does not prove that the hull was asbestos-free, and does not establish or defeat exposure, causation, liability, or legal eligibility. NHHC/DANFS was unavailable through the live fetch and underlying NARA logs were not retrieved.

[7]CourtListener API v4 authenticated search via /Users/charlesfletcher/devin-prompts/cl-auth-search.py, query USS LST-609, type opinion [court_record]
- Locator
- Authenticated helper output: exact-name opinion query count 3; docket and hull-number helper invocations emitted only the authenticated-request diagnostic before paced execution did not complete
- Finding type
- historical_record
- Finding
- An authenticated CourtListener API v4 exact-name opinion search for USS LST-609 returned three non-qualifying name/token collisions: Newport News Shipbuilding and Dry Dock Company v. United States (1967), Garden Ridge, L.P. v. Clear Lake Center, L.P. (2015), and Tyrone Berry v. State (2015). None names this hull or qualifies as asbestos litigation concerning it. Exact-name docket and hull-number opinion/docket searches were initiated through the required helper but did not complete before the fleet pacing limiter held the request; no result is inferred from those incomplete requests.

- Limitations
- This is not a complete litigation clearance. Only the exact-name opinion request completed; the other required exact-name/hull-number request types remain a documented CourtListener pacing gap. The three returned results are classified as name/token collisions, not exposure evidence. CourtListener also does not cover all state, bankruptcy, or non-indexed records.
