   Finding

   NHHC documents that Naval Station Subic Bay's shipyard facilities included 'the floating dry dock Dewey (YFD-1)'; that 'the 500-foot dry dock left Maryland on 28 December 1905 and arrived at Subic Bay on 10 July 1906' towed by four U.S. Navy ships across the Atlantic, through the Mediterranean and Suez Canal, across the Indian Ocean, and up through the China Sea to Luzon; that Subic became an important Asiatic Fleet repair facility because Dewey could accommodate the fleet's largest battleships while Cavite had no battleship docking facilities and too shallow a port for a floating dry dock; that in 1922 all Subic shipyard work except repairs requiring the floating dry dock was transferred to Cavite; that 'in the summer of 1941, as war with Japan seemed imminent, the Navy moved Dewey to Mariveles'; and that 'the dry dock was scuttled on 8 April 1942 to prevent it from being used by the Japanese. The Japanese managed to raise it, but it was sunk later by American forces.'

   DANFS documents two Langley dockings in Dewey: 'In July 1940, Langley shifted to the Naval Station, Olongapo, Zambales, Luzon, P. I., to be serviced by the floating dry dock Dewey (YFD-1). This was completed on 24 July in preparation for the ship conducting operations at various Philippine locations'; and in 1941, after the Asiatic Fleet tactical exercise, 'she departed Jolo and returned to Cavite to prepare for her annual inspections and maintenance availability. She shifted to Olongapo and docked in Dewey on 12 May.' The second docking is corroborated by National Archives photo 80-G-1041082 of Langley drydocked in Dewey at Olongapo in May 1941 - the NHHC photo caption and DANFS caption give 27 May 1941, NavSource's caption gives 26 May.

   Same-day United Press wire reporting documents the dock's 1910 sinking: 'The drydock Dewey, the largest floating drydock of the American navy, sank in 70 feet of water at Olongapo, Subic bay, today. In some unknown manner the water displacing valves of the drydocks were left open... The costly machinery of the Dewey is ruined, according to naval engineers.' The report further records that she was installed at Olongapo 10 July 1906 after being towed from Hampton Roads; that ships of all nations used the dock; that she could take vessels of the Dreadnought class; built at Sparrows Point by Maryland Steel for about $1,000,000-1,040,000; measured (per the report) 500 x 106 feet; hoisting machinery 'could lift 24,000 tons dead weight'; and that during her Suez transit she scraped the canal sides, the U.S. paying $40,000 for repairs.

   A wire-service news report, not an official record - details such as dimensions (500 x 106 ft), the 24,000-ton lift claim, and 'machinery ruined' are period journalism, not engineering findings, and diverge from NavSource specifications (501 3/4 x 100 ft, 18,500 t). The wire report does not state the cause beyond 'unknown' open valves and does not cover the salvage; the dock's return to service is proven by her documented operation through 1941, and secondary sources citing the National Marine Engineers' Beneficial Association journal give sinking while receiving a torpedo boat and raising undamaged 29 June 1910 - carried as partially verified only.

   A firsthand newspaper account of the 1906 delivery voyage by a passenger aboard the dock documents her internal arrangement and crew: 'In one of the sides, away up near the "roof," are the living quarters, while the other contains the operating apparatus, pumps, boilers, dynamos, etc. A bridge at either end spans the intervening space'; quarters 'roomy, well lighted and ventilated' with cabin, forecastle, staterooms, mess and bath; 'The dock carries a company of thirty-two, divided into the captain's and the fo'castle mess' including Captain J.D. Wood (sailing master), chief boatswain Phillip Mullen in charge of towing gear, designer Hans Hanssen as advisory dock expert, J.H. Detwiller who would remain in Manila as permanent dock master, engineers, firemen, fourteen seamen, a rigger, a carpenter, and a wireless operator. The narrative records towing-chain partings, a collision near-miss with Glacier, coaling stops for the tug Potomac, and the dock underway 'navigated like any other seagoing ship' despite having 'neither means of propulsion nor steering gear of its own.'

    The official Bureau of Yards and Docks history describes the dock: 'The other dock, the Dewey, was a 16,000-ton dock, built in three sections, and capable of docking itself. It was constructed in 1903-1905, also at Sparrow's Point, Md., and was towed via the Suez Canal to the Philippines. The saga of this voyage is an epic of ocean towing history. The Dewey was still in service at Olongapo when the Japanese invaded the Philippines early in 1942. It was scuttled by the American naval forces before they abandoned the station.' The same chapter describes the WWII three-piece steel YFD docks as 'modern counterparts of the old Dewey Dock' - the design lineage she founded.

    Finding

    A floating dry dock with an onboard steam plant - boilers, pumps, and dynamos documented by a 1906 firsthand account - in continuous Navy service 1905-1942 sits inside the era when steam-system insulation, flange gaskets, and machinery packing commonly contained asbestos. Her 36-year service spanned the First World War and the interwar period in which such materials became standard Navy practice, so any original or repair-era insulation in her machinery spaces and machine shops is reasonably consistent with asbestos-containing materials. Typical applications bounded to this hull's plant: boiler and steam-line insulation/lagging, valve and flange gaskets, and machinery packing - confined in scale to a dock-side machinery space rather than a warship propulsion plant.

    Archival leads (not retrieved - no box-level reproduction performed): National Archives still-photo series hold the dock's official photography already identified in NavSource captions (80-CF-22672-1 and -3: Jason in dock March 1932; 80-G-1041082: Langley in dock May 1941). Bureau of Yards and Docks records (RG 71) are the plausible repository for construction contract, acceptance, and casualty (1910 sinking) documentation; 16th Naval District and Asiatic Fleet records (RG 181 / wartime command files) for docking logs and the 1941-42 Mariveles transfer and scuttling report.

    Finding

    Litigation sweep (all 4 required base queries executed 2026-10-04): exact-name opinion "USS Dewey" (type=o) returned count=1 - United States v. Martinez, 12 M.J. 801 (N.-M.C. Mil. Rev. 1981), CL opinion 8663545, a Navy court-martial naming 'the USS DEWEY (DDG 45)': name collision, not asbestos litigation. Exact-name docket "USS Dewey" (type=r) returned count=10: Pacific Controls Inc. v. Cummins (S.D.N.Y. 1:19-cv-03428) matched via attorney firm Dewey Pegno & Kramarsky LLP - name collision; Boesenhofer v. AECOM (E.D. Pa. 2:17-cv-01072) and In re Asbestos Products Liability Litigation No. VI (MDL-875, JPML) are asbestos dockets whose 'USS Dewey' match context is not exposed in the docket-level response - Boesenhofer's exposure allegations concern a civilian boilermaker at Philadelphia Naval Shipyard 1966-1997, decades after this hull's 1942 loss and on the wrong coast, so any vessel match is a destroyer-hull collision, not this drydock; the remaining seven rows (U.S. v. Lutz; U.S. v. Butler x2 - same docket 9:25-cr-80093 returned twice; U.S. v. Wisidagama; Serrano v. Commonwealth of Puerto Rico; Cruz-Serrano v. Commonwealth of Puerto Rico; Gilbert v. Rig Ventures) are criminal or civil dockets with no asbestos nexus on face - other litigation. Hull-number opinion "YFD-1" (type=o) returned count=0 - no result. Hull-number docket "YFD-1" (type=r) returned count=5, none with 'YFD' in the serialized payload (nested-index matches, likely document-code/OCR noise): Seago v. Gail (prisoner civil rights), Circuit City Stores bankruptcy, U.S. v. Peace (prisoner), Garth D Ryan v. GJB Enterprises (securities), Pharaon bankruptcy - all other litigation, no vessel or asbestos nexus on face. No qualifying asbestos litigation naming this hull identified.

    Limitations

    CourtListener indexes published opinions and docket metadata - unindexed pleading-stage complaints naming the vessel would not appear, and PACER-only filings are outside the index. The hull's 1942 loss precedes the modern asbestos-litigation era. Absence of indexed hits is not proof no filing ever named the hull. Name-collision risk in any hit: destroyers Dewey (DD-349) and Dewey (DLG-14/DDG-45), the Dewey law-firm names (Dewey Ballantine, Dewey & LeBoeuf), and persons/parties surnamed Dewey.

    Finding

    No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum documentation, or verified litigation naming Dewey (YFD-1), the Dewey Dry Dock, or Floating Dry Dock No. 1 was found in the public sources searched (see search_ledger). A ship-specific negative is expected for this hull: the dry dock was scuttled in 1942 and resunk by American forces, so no post-war survey, museum record, or abatement documentation can exist, and no litigation naming her was located.

    Limitations

    Absence of a located public record does not prove absence of asbestos aboard - a steam-machinery-carrying structure of her era plausibly carried asbestos-containing components, and her repair work on asbestos-era fleet units is an undocumented occupational question. Does not establish presence or absence; does not establish or defeat any claim of exposure or legal eligibility.
