    Limitations
    The page is an oral-history account focused on PC-469. It confirms only PC-556's Coast Guard manning and commissioning year; it does not give PC-556's builder, exact commissioning date, service history, complement, specifications, transfer, or final disposition, and it says nothing about asbestos.

    Finding type
    gov_survey
    Finding
    GAO reviewed Navy efforts to protect workers from asbestos exposure at Long Beach and Norfolk Naval Shipyards and considered Navy ship asbestos use and removal. The report's overview states that Navy officials described asbestos in ship components and thermal insulation as the Navy's major shipboard use; it also says the Navy issued a policy in October 1975 to eliminate asbestos where suitable alternatives had been designated.

    Limitations
    Navy-wide program context only. The report does not name PC-556 or its builder, does not establish any material aboard this hull, and does not establish crew exposure, quantities, or remaining asbestos. No hull-specific exposure or material claim is inferred from it.

    Finding type
    historical_record
    Finding
    No ship-specific asbestos survey, material inventory, abatement record, hazmat disclosure, or qualifying asbestos litigation record for USS PC-556 was verified in the sources reviewed for this record. This is a public-source search result, not evidence that asbestos was absent aboard the vessel.

    Limitations
    The CourtListener sweep is incomplete: the first authenticated helper request was stopped by the fleet pacing limiter, and the remaining exact-name/hull-number opinion and docket queries were not run. Firecrawl search and scrape were unavailable because the keyless MCP quota was exhausted. Absence of a located record is not proof of absence of asbestos or litigation.
