    Finding
    Official DANFS history: laid down 1918-07-16 at Buffalo, NY by Ferguson Steel & Iron Co. as Ammonoosuc; renamed Bagaduce 1919-02-24; launched 1919-04-05; commissioned Buffalo 1919-09-18 (Lt.(j.g.)

    Crew (design complement 44); navy-yard support personnel at documented stations (NY Navy Yard, Washington Navy Yard, Philadelphia, Mare Island)
    Limitations
    Official service history contains no insulation, material, or asbestos information whatsoever - it documents operations, dates, and stations only. DANFS dates the Miami hurricane '18 August 1926'; the Great Miami Hurricane made landfall 1926-09-18 (see correction row ev-uss-bagaduce-at21-05). Does not establish asbestos presence, absence, quantity, exposure, or eligibility.

    asbestos_application
    Finding
    Secondary archival compilation lists the class machinery as one Allis Chalmers vertical triple-expansion steam engine, two Babcock & Wilcox boilers (200 psi saturated steam), two 25 kW turbo-drive ship's service generators, single propeller, ~1,800 shp. A reciprocating steam plant of this construction era carried boiler and steam-drum insulation, steam-line lagging, flange and valve gaskets, and machinery packing - applications that era-typically contained asbestos fiber.

    Construction trades (Buffalo, 1918-19); engine-room crew (boiler/machinery spaces)
    Limitations
    NavSource is a reputable secondary compilation, not a primary record; its spec block conflicts with the DANFS type line on beam (35'7" vs 30'), draft (15'6" vs 14'7"), speed (12.8 kts trial vs 12.4), and complement (5 officers/56 enlisted vs 44) - as-built/full-load vs design figures. The source does not say 'asbestos' and does not document materials aboard this hull; asbestos content is era inference, not ship-proven. Does not establish quantity, location, condition, individual exposure, or causation.

    Finding type
    gov_survey
    Finding
    GAO documented the Navy's asbestos-protection program and reported the Navy's own account that all ships contain some asbestos in components such as clutches and electric cables, and that thermal insulation was the Navy's major use of asbestos aboard ships - the insulation regime in force during this hull's WWII service era. Fieldwork was at Long Beach and Norfolk Naval Shipyards.

    historical_record
    Finding
    Federal weather documentation fixes the devastating Miami hurricane landfall at September 18, 1926 (Category 4). The DANFS entry for this hull dates the same storm '18 August 1926' - an apparent date error in the official record; Bagaduce's documented relief response (provisions, harbor clearance, waterfront guard support) followed the September 18 storm.

    Finding
    No qualifying ship-specific record located: no asbestos survey, abatement contract, hazmat disclosure, government report, or docketed case naming USS Bagaduce (AT-21/ATO-21) was found in the public sources searched (see search_ledger). The only 'Bagaduce' litigation hits located are Penobscot Nation treaty litigation concerning the Bagaduce River region of Maine (D. Me. 1:12-cv-254) - a name collision, not the vessel. Asbestos content-site coverage of 'USS Bagaduce' names the second hull, ATA-194, not this ship.

    Limitations
    Absence of a located public record does not prove absence of asbestos aboard - a 1919 reciprocating-steam tug's insulation regime is era-consistent with asbestos use. Does not establish that asbestos was or was not present, and establishes or defeats no claim of exposure or legal eligibility. CourtListener API was rate-limited during the search window; site-index coverage used - see search_ledger.
