   Class-level construction narrative: the WWII 173-foot patrol craft was 'steel hulled, twin diesel propelled'; 'in addition to 403 173-foot PC-class patrol craft ordered for the U.S. Navy in 1941, eighteen 173-foot hulls were ordered for use as minesweepers, as the Adroit class' - given names AM-82 through AM-99 (Adroit, Advent, Annoy, Conflict, Constant, Daring, Dash, Despite, Direct, Dynamic, Effective, Engage, Excel, Exploit, Fidelity, Fierce, Firm, Force). 'AM 82 through 88, built at Portland, Oregon' (Commercial Iron Works per the hull record); the other eleven at other yards. As completed they differed from the PCs in the sweep-cable reel at the stem, a longer superstructure with a squat dummy funnel, a kingpost and boom, and two stem davits. 'Only the Annoy (AM-84) is recorded as having been used to sweep for mines ... the others principally were employed as convoy escorts.' Atlantic units cycled through Norfolk Navy Yard May-June 1944 for removal of MCM gear and added ASW/AA ordnance; 'the Pacific units were modified at Pearl Harbor' - this hull's documented conversion yard. 'On 1 June 1944, all 18 lost their names and were reclassified PC-1586 through 1603.' 'At 450 tons full load, the Adroit class displaced 18 tons more than did the PCs. All but the last four built were propelled by two 1,770 brake horsepower Cooper-Bessemer GNB-8 diesels; AM-96-99 were given 1,440 brake horsepower Busch-Sulzer BS 539 diesels ... able to achieve 16.8 knots at 330 tons displacement ... about 4,000 nautical miles at 12 knots, and the normal crew comprised four officers and 61 enlisted personnel.'

   asbestos_application

   Finding

   Era/design inference: this hull is a 1941-42-built, steel-hulled, twin-diesel vessel - a PC-461-type hull completed as a minesweeper - with no boilers and no steam distribution, so its insulation load was materially lighter than a steam combatant's but not negligible: a steel hull still carried accommodation joiner work, electrical systems, and machinery requiring lagging and gasketing, and construction fell squarely inside the Navy's asbestos-use era (substitution did not begin until the early 1970s). Era-typical asbestos applications for a vessel of this type and period: engine and exhaust-system lagging on the two diesels and generator sets; machinery gaskets and packing; electrical-cable insulation; joiner/accommodation insulation; deck coverings/floor tile of the period; winch and windlass brake linings. Exposure-relevant populations if any such material was present: Commercial Iron Works construction trades (Portland, 1941-42 - the yard closed 1946); the commissioned crew (~65) across the 1942-45 Noumea/Guadalcanal/Treasury Islands and Ulithi/Saipan-Iwo Jima service; Pearl Harbor yard workers during the documented December 1942 voyage repairs and the 1944 conversion modification; San Francisco deactivation workers (1945); and the Maritime Commission disposal workforce (1948, fate of the hull undocumented).

   Inference from documented design, machinery type, and construction era - NOT a hull materials record. No survey, specification, or material schedule naming AM-82/PC-1586 was located; establishes no asbestos content, quantity, location, condition, individual exposure, or causation. The diesel (non-steam) plant weakens the inference relative to steam vessels of the same era, though the steel hull and 1941-42 construction keep it within the asbestos-era window.

   Finding

   Program-level documentation of the asbestos window containing this hull's entire construction and commission: GAO HRD-80-2 records that the Navy's product specifications for thermal insulation were changed in 1973 to specify asbestos-free materials, but asbestos materials already purchased were still installed - 'some ships were delivered with asbestos insulation as late as May 1978'; the Navy's elimination policy issued October 1975. A Navy letter to GAO dated 5 January 1979 (T.J. Bigley to Robert F. Hughes, quoted in the Notre Dame Journal of Legislation) states: 'all ships presently in service contain some quantity of asbestos.' AM-82/PC-1586 was built 1941-42 and in commission 1942-45 - entirely inside the pre-1973 as-built asbestos era.

   No case located names this hull (see negative_finding row ev-10 and search_ledger). Doctrinal context only for the vessel's type: claims arising from Navy-vessel asbestos exposure ran under maritime law against equipment manufacturers, and the Supreme Court's DeVries decision settled the 'bare-metal defense' framework - manufacturers that supplied bare equipment had a duty to warn where their products required asbestos-containing parts. It illustrates the litigation posture a claim arising from service aboard a WWII diesel minesweeper/subchaser would have faced; no such claim naming Adroit, AM-82, or PC-1586 was located. CourtListener name collisions checked and classified: 'Adroit' hits are Adroit Health Group LLC and Adroit Children LLC litigants (per the same-day batch-1399 sweep of the same index) - not the ship; the same-name Cold War hull USS Adroit (AM/MSO-509) is a different vessel.

Expected available in 16050 seconds' - the shared quota was exhausted by earlier same-day batch work; no unauthenticated queries were run). The litigation sweep therefore ran through Google-indexed CourtListener content and general web: the only 'Adroit' hits are name collisions (Adroit Health Group LLC, Adroit Children LLC litigants - per the same-day batch-1399 sweep of the same index) and generic asbestos dockets naming no vessel; no 'PC-1586' or 'AM-82' vessel reference surfaced in any opinion or docket index reachable. Non-authoritative marketing rosters carry the name in generic ship tables - mesothelioma.net's patrol-boats page lists this hull TWICE under both designations ('USS Adroit (AM-82)' and 'USS PC-1586') - excluded per source rules; they carry no hull-specific evidence, and the double-listing independently validates the all-tier VERIFY consolidation of the two designations into one canonical record.

    Absence of a located public record does not prove absence of asbestos aboard - a 1941-42 steel-hulled naval vessel is era-consistent with asbestos-containing materials even accounting for its lighter diesel insulation load. The hull was disposed of via the Maritime Commission in 1948, so no present-day survey pathway exists. The CourtListener sweep is incomplete (shared-cap exhaustion) - a fully authenticated re-sweep of opinions and RECAP dockets remains an open verification step. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.

    Finding

    Archival leads (not retrieved - require research-room or reproduction order; no spend authorized; NARA catalog returns only its JS application shell to automated fetch): (a) NARA RG 24 deck logs, Jul 1942 - Dec 1945 - the documentary base for the documented operations; (b) muster rolls for the commission period; (c) NHC photo S-511-13, the 6 January 1941 'Adaptation of PC 452 Type' design plan credited on the NavSource page - the closest existing thing to a design record for the class; (d) NARA RG 19 BuShips records per the asbestos guided-topic page - hull files 'AM82'/'PC1586,' class files for the PC-461/Adroit series, 'QM/Commercial Iron Works' contract correspondence, P-11 minesweeper GIBs, and S39/S48/S103 hull-series drawings - the plausible home of hull-level material schedules; (e) RG 181 Pearl Harbor Naval Shipyard job files for the Dec 1942 voyage repairs and the 1944 conversion modification (the Pacific units' documented conversion yard per the class index); (f) the U.S. Maritime Commission disposal record for the 18 March 1948 transfer - the only plausible documentary path to the hull's post-1948 fate.

    Limitations

    Record-group mapping only - no box-level retrieval performed; existence of asbestos-specific documents for AM-82/PC-1586 is unknown until surveyed in person. Deck logs, muster rolls, and contract files are personnel/operations records, not materials documentation; the BuShips design file is the best candidate for a material schedule. Nothing in this row is an asbestos finding.
