    DANFS Liberator entry, paragraph II (AMc-87) with spec line
    Finding type
    vessel_history
    Finding
    DANFS documents: the second Liberator (AMc-87) was laid down 5 May 1941 by F. L. Fulton Works, Antioch, Calif.; launched 6 September 1941; sponsored by Miss Pay Hill; placed in service 22 February 1942, Lt. (jg.) James W. Dawnes in command. Assigned to the 13th Naval District, she operated out of Puget Sound until sailing for Alaska April 1944, swept the Alaskan shipping lanes, and returned to the 13th Naval District in September. Reclassified IX-202 on 20 December 1944 and used as a general utility ship until placed out of service 3 May 1945; turned over to WSA 2 July 1946 for disposal. Spec line: '(AMc-87: dp. 195; l. 97'1"; b. 22'; dr. 9'; s. 10 k.; a. 2 .50 cal. mg., 2 .30 cal. mg.; cl. Accentor)'.

    Authoritative Navy ship-history entry; contains no asbestos, materials, or industrial-hygiene information whatsoever. States no strike date, complement, or final disposition beyond the 1946 WSA turnover for disposal. The IX-202 'general utility ship' station is unnamed. 'Placed in service' is DANFS's wording; NavSource records the same date as a commissioning.

    Finding
    Official 1945 characteristics register records the strike: Vol. III p. 613 table 'VESSELS STRICKEN FROM NAVY LIST (Auxiliaries, Unclassified and District Craft only) - The following have been stricken from the Navy Register since 1 February, 1944' carries the row 'LIBERATOR . IX 202 . Miscellaneous, unclassified . 19 May 1945' - a primary-source strike date that also corroborates NavSource's secondary listing. The same volume's IX index annotates 'IX202 LIBERATOR ( returned to W. S. A.)', and its alphabetical ship index lists 'Liberator (ex-AMC87) IX202 Miscellaneous-Unclassified' pointing only to p. 613 - the hull carried no characteristics row because she was already stricken at compilation.

    Limitations
    Authoritative strike and designation record; contains no asbestos, materials, characteristics detail, or disposal-file information. The '(returned to W. S. A.)' annotation reflects the volume's loose-leaf update state and does not itself date the WSA turnover - DANFS supplies 1946-07-02. No characteristics row exists for IX-202 in this volume (stricken before compilation), so configuration detail rests on the DANFS spec line and NavSource.

    Finding
    Official 1945 index carries the designation trail within one hull: the coastal-minesweeper list shows 'AMC87 LIBERATOR (now IX202)' under the 'No. 61-110 Class' grouping, and the alphabetical ship index carries 'Liberator (ex-AMe87) IX202 Miscellaneous-Unclassified - x' - the volume's 'x' marker denoting a Vol. III data entry (which resolves to the p. 613 stricken table). Establishes AMc-87 and IX-202 as the same physical hull in the Navy's own register.

There was only one basic design - the 97-foot, 10-knot "Accentor" class.' Its hull table lists 'AMc 87 Liberator Fulton Shipyard 97 [ft] 205 [t] 22-Feb-42 Sold 1946' - corroborating the builder, dimensions, in-service date, and a 1946 sale, and establishing the wooden-hull character of the Accentor design relevant to bounding asbestos inference (no steel hull, no steam plant).

    Specialist trade compilation, not an official record; consistent with DANFS on builder/dates. Its 205-ton figure conflicts with DANFS 195 t. (likely full vs. light displacement - unresolved, in gaps). 'Sold 1946' is a compilation datum; no WSA disposal case file or buyer is documented. 'Wooden-hulled' is a class-level statement applied to this hull via the documented class design. No asbestos information.

    Finding type
    asbestos_application
    Finding
    GAO-era documentation establishes that asbestos was standard in Navy ship construction and overhaul materials of the period (thermal insulation, gaskets, packing, deck tile). For a wooden-hulled diesel coastal minesweeper with no steam plant, the plausible subset on this hull type is confined to machinery-exhaust lagging, gaskets, packing, electrical insulation, and deck materials - a materially smaller asbestos profile than steam-powered combatants.

    Limitations
    Program-level era context only - the GAO report does not name this hull, the Accentor class, or small diesel minesweepers, and its fieldwork concerned naval shipyards. No application aboard this hull is established; equally, absence of the steam-plant pathway is a structural inference from the documented diesel propulsion and wooden hull, not a certification that no asbestos was present.

    Sweep not executed this session - fleet-wide CourtListener pacing (shared ~114 req/hr budget across sessions) exhausted; helper guidance is not to retry in a loop. This is a coverage gap logged honestly, not a negative result: litigation exposure for this hull is unexamined in this batch. A small 1941-46 wooden minesweeper with no documented asbestos record is a low-likelihood litigation target, but that is inference, not a finding.
