    Limitations
    DANFS is a service history, not a material survey; it does not identify asbestos-containing materials or establish asbestos presence or absence. The live NHHC page returned HTTP 404; an archived 2015-04-09 copy of the official entry was retrieved and is cited as archived. Post-service private ownership and final fate are not included here because authoritative confirmation was not located.

    Finding
    No ship-specific asbestos documentation was located in the accessible official sources reviewed for this record. DANFS does not discuss asbestos. This is a bounded research finding, not evidence that asbestos was absent from the vessel.

    Limitations
    The live NHHC page returned HTTP 404; the archived capture was retrieved. Firecrawl MCP was quota-exhausted. Two CourtListener helper invocations (exact-name opinion and docket) were stopped by the fleet pacing limiter before HTTP requests, and the hull-number searches were not sent. No comprehensive shipboard materials inventory or abatement file was located. The finding must not be treated as proof of absence or as a completed litigation search.
