- The live NHHC history.navy.mil DANFS page for this hull returns HTTP 404 as of 2026-09-23 (link rot / not migrated to the current site) and no replacement URL was found on history.navy.mil; this is a Wayback Machine capture of a long-standing transcription mirror used elsewhere in this project when NHHC pages 404 (see BATCH-01-REPORT.md). Text matches the NavSource summary (ev-02) verbatim on all overlapping facts. Contains no asbestos, insulation, or hazmat information of any kind; supports no asbestos claim.

- NavSource Naval History photo-archive record for Conqueror (AMc-70): Accentor-class coastal minesweeper; laid down 8 May 1941 by Warren Fish Co., Pensacola, FL; placed in service 6 March 1942; placed out of service 6 December 1945 and transferred to the War Shipping Administration for disposal; struck from the Naval Register 3 January 1946; transferred to the War Shipping Administration again in August 1946 and sold; fate unknown. Specifications: displacement 195 tons; length 97 ft 1 in; beam 21 ft 10 in; draft 9 ft 1 in; speed 10 kts; complement 17; armament one .50 cal. machine gun; propulsion one 400 bhp Atlas 6 HM-2124 diesel engine, one shaft.

- Volunteer-run naval history photo archive, not a government site, but it functions here as an archival mirror/index citing an underlying National Archives photograph (80-G-15962) and DANFS text; used consistently with this project's prior treatment of hazegray/HyperWar-style mirrors. Armament figure (one .50 cal. gun) conflicts with the two-gun figure given by some secondary compilations - carried as a discrepancy in gaps, not resolved. Contains no asbestos, insulation, or hazmat information; supports no asbestos claim.

[3]Cross-reference of ev-uss-conqueror-amc70-01 (DANFS) and ev-uss-conqueror-amc70-02 (NavSource), both of which omit "USS" [nhhc_danfs]
- Locator
- Title lines of both cited pages
- Finding type
- historical_record
- Finding
- Both primary-source mirrors reviewed (the DANFS entry and the NavSource archive page) name this vessel "Conqueror (AMc-70)" without a "USS" prefix. This is consistent with her status as a small district/auxiliary craft "placed in service" rather than commissioned - Navy custom of the period generally reserved the "USS" prefix for commissioned ships. This record uses "USS Conqueror" in the name field per the batch task's canonical naming instruction; the primary-source-verified form is "Conqueror (AMc-70)" and no source establishes a formal commissioning.

- asbestos_application
- Finding
- Peer-reviewed historical scholarship documents that asbestos was used extensively as a fireproofing and insulating material across U.S. shipbuilding generally during World War II - the same wartime shipbuilding program and era (1941-1942) in which this vessel was built at Warren Fish Company, Pensacola, FL.

- WWII U.S. shipyard construction workers generally (era context, not this vessel's crew)
- Limitations
- This is general WWII shipbuilding-industry scholarship, not a class-specific or hull-specific record - it does not name this vessel, the Accentor class, AMc-type coastal minesweepers, wooden-hull construction, or diesel-engine plants specifically, and the paper's documented exposure context concerns shipyard construction workers, not vessel crew. It does not establish that asbestos-containing material was installed aboard, or is present aboard, this hull. Marked context_only (not class_or_era) because no source ties asbestos use specifically to this vessel's class or engineering plant type.

- Finding
- No qualifying ship-specific or class-specific asbestos record was located for this hull: no survey, abatement contract, hazmat disclosure, museum/archival statement, or GAO/regulatory finding names Conqueror (AMc-70), the Accentor class, or AMc-type coastal minesweepers generally in connection with asbestos. GAO's 1979 Navy asbestos-exposure review (HRD-80-2) was checked and found inapplicable - its fieldwork covered Long Beach and Norfolk Naval Shipyards under a 1975-1979 Navy asbestos-removal policy, a period that postdates this vessel's 1945 decommissioning and 1946 civilian sale.

Does not establish or defeat any exposure claim or legal eligibility.

[6]CourtListener API v4 authenticated search (via project helper script), opinion and RECAP-docket collections [court_record]
- Locator
- Queries: "USS Conqueror" (opinion, count 0; docket, count 0); "AMc-70" (opinion, count 2, both collisions; docket, count 19, all collisions); "Conqueror AMc-70" (docket, count 19, same collision set). See search_ledger.
- Finding type
- litigation_documented
- Finding
- CourtListener searches (opinions and RECAP dockets) for the exact phrase "USS Conqueror" returned zero results in both collections. Searches for the hull designation "AMc-70" (opinions and dockets) returned only name-collision noise - none reference this vessel: AMC Entertainment Holdings, Inc. v. XL Specialty (Del. Super. Ct. 2025, insurance coverage dispute), Salinas, Martin (Tex. 2015, capital habeas matter), Sanchez-Betances v. Aspen American Insurance Co. (D.P.R. 2018, admiralty insurance dispute unrelated to this hull), In re Oil Spill by the Oil Rig Deepwater Horizon MDL (environmental matter), and other unrelated dockets matching only fragments of the query terms. No qualifying asbestos litigation, and no litigation of any kind, naming Conqueror (AMc-70) was located.

- Limitations
- CourtListener/RECAP coverage of federal dockets is not complete for all jurisdictions and time periods, and a name/hull-number search cannot surface a case that never used either string (e.g., a case referring only to "the vessel" or an operator name). One planned supplementary query (builder name "Warren Fish Company Pensacola") could not be completed - the fleet-wide CourtListener rate limiter paced out mid-session and was not retried given low expected materiality (a 1941 civilian boatbuilder is an implausible litigation search term). This is a negative finding on the searches actually completed, not a certification that no case exists.
