- Finding
- Compiled service record for ARD-11: laid down date unknown at Pacific Bridge Co., Alameda, CA; commissioned USS ARD-11 on 26 October 1943 at Mare Island Navy Yard, Vallejo, CA, CDR William Hartenstein in command; decommissioned 15 June 1944 and placed in service; struck from the Naval Register 15 April 1974; disposed of via Security Assistance Program cash sale to Mexico 1 July 1974, fate unknown. Specs: 4,200 t light, 482'7" length, 71' beam, 5' draft, 2 single 20mm mounts, complement 6 officers + 125 enlisted. Ribbons: American Campaign Medal, World War II Victory Medal (no Asiatic-Pacific award listed). Dated Navy Yard Mare Island photographs place the dock at Mare Island 1944-10-25 (USS Bowfin SS-287 in dock), 1945-09-07 (with USS LST-130), 1947-02-14 (inside dry dock No. 3), 1948-04-23 to 1948-06-07 (USS Carp SS-338 docking), and 1954-07-01 (Grayback SSG-574 keel-laying ceremony).

- Limitations
- NavSource is a compiled secondary reference, not an official publication; its dates are corroborated by the official ServPac history CO listing, the NAVSHIPS Ships' Data 1945 entry, and the NARA deck-log index range (all carried separately). Specifications are class-typical figures; its 482'7" length differs from Ships' Data's 485'8" overall - variance logged in gaps. The dated official photographs place the dock at Mare Island on those dates but do not constitute a complete station list. No asbestos content in source.

- Finding
- The Bureau of Yards and Docks' official history describes the ARD program: the experimental ARD-1 (1934, 2,200-ton one-piece ship-form dock with bottom-hinged stern flap gate, own diesel-electric power plant, pumping plant, repair shops, and crew accommodations) was followed by about 30 enlarged docks 'constructed and deployed throughout the world during the war,' delivered during 1943-44 'at an average rate of more than one a month.' Type definition given: 'ARD - Auxiliary Repair Dock. Mobile, military, steel unit dock, ship-form hull, with a normal lifting capacity of 3,500 tons, for destroyers, submarines, and small auxiliaries.'

- Finding type
- asbestos_application
- Finding
- Era/type inference: ARD-11 was built in 1943 at Pacific Bridge Co. to the wartime ARD design whose enclosed bow and wing-wall volume held a diesel-electric power plant, pumping plant, repair shops, storerooms, and crew berthing - the compartments where WWII-era Navy construction standardly applied asbestos-containing thermal insulation, gaskets, and packing. Peer-reviewed scholarship documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII, the program under which this dock was mass-produced.

- Finding
- Asbestos-containing material is documented at the facility where ARD-11 spent her U.S. career: the former Mare Island Naval Shipyard is an EPA-tracked federal-facility cleanup site (EPA ID CA7170024775, state-lead cleanup under California DTSC), and the site's Basewide Environmental Baseline Survey records ACM confirmed in floor tiles, transite, steam insulation, and steam pipe joint insulation, with 'ACM issues ... currently being addressed by the Mare Island Naval Shipyard, the Department of Labor' - repeated across parcel entries. Dated Navy Yard photographs place ARD-11 operating at this yard from 1944 through at least 1954.

Establishes that ACM existed at the yard where the dock operated; establishes nothing about material aboard ARD-11. Survey documents post-date the dock's 1974 disposal. No quantity, exposure, or causation statement.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum/museum-quality documentation, or docketed case naming ARD-11 was found in the public sources searched. NHHC's DANFS has no entry for ARD-11 (canonical URL returns 404; NavSource confirms 'There is no DANFS history available for ARD-11'). The Naval Vessel Register excludes ships and service craft disposed of prior to 1987, so the 1974 disposal places the hull outside its coverage. See search_ledger rows sl-uss-ard-11-01 through sl-uss-ard-11-12.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - a 1943 wartime-built floating dock with machinery, shops, and berthing spaces is era-consistent with asbestos-containing construction, and her post-1974 Mexican service is essentially undocumented. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.

- Finding type

- Finding
- CourtListener authenticated API v4 opinion searches returned no qualifying asbestos-litigation result naming this hull: '"ARD-11"' produced 14 hits, all reviewed and classified name collisions (criminal appellants surnamed 'Ard', e.g. Ard v. State; OCR text-noise matches) with none concerning the vessel; '"USS ARD-11"' returned zero results. Spaced-variant and RECAP-docket queries were attempted but could not complete - the fleet pacing budget was spent at session close; logged in the search ledger.

- Limitations
- Opinion search completed and collision-reviewed; RECAP docket path and the spaced variant '"ARD 11"' could not be run before the shared fleet pacing budget was spent - residual gap logged. CourtListener indexes published opinions and RECAP dockets - a null result covers litigation that reached the index; it does not cover trial-level filings, settled cases, or claims systems (asbestos trusts) that never produced an opinion. Absence of a case is not absence of exposure.
