    PDF table entry YMS-447
    Finding type
    historical_record
    Finding
    NARA's Special List #44, Ship Numbers, lists YMS-447 with a deck-log coverage interval from 1944-06-29 through 1945-03-27. This establishes the existence and indexed date span of deck-log records for the hull, not the ship's commissioning, service events, or transfer history.

    Limitations
    This is a finding aid showing the indexed coverage dates of deck logs. It does not itself establish a specific event on either endpoint, commissioning, transfer, service history, or asbestos aboard the vessel.

    Opening research scope statement
    Finding type
    historical_record
    Finding
    NARA states that it preserves Department of the Navy permanent records and that only some Navy records have been digitized; many remain in paper or microfilm formats. This identifies a relevant archival research path and limits the meaning of an online search that did not retrieve additional hull-specific records.

    Limitations
    General archival guidance only; it is not evidence about the ship, its asbestos condition, or a completed search of non-digitized holdings.

    Finding type
    asbestos_application
    Finding
    No ship-specific asbestos survey, abatement record, hazmat disclosure, or qualifying asbestos litigation record was located in the sources successfully reviewed for this batch. Ship-specific asbestos documentation is unknown.

    2026-10-04
    Limitations
    A bounded search result, not proof that records do not exist. Firecrawl search/scrape was unavailable due to exhausted hosted quota; CourtListener helper requests did not return results before tool timeouts; NARA notes that many Navy records are not digitized. No class-era inference is used to claim asbestos aboard this hull.
