- Official DANFS record for this hull: Admirable-class minesweeper (dp. 625; l. 184'6"; b. 33'; dr. 9'9"; s. 14.8 k.; cpl. 104; a. 1 3", 2 40mm., 6 20mm., 3 dcp., 2 dct.; cl. Admirable); name means 'a weapon with a long shaft and a sharp steel head.' Laid down 26 October 1942 by American Shipbuilding Co. - DANFS prints 'Cleveland, Ohio' (the corporate HQ; the actual build yard was Lorain - see ev-06(a)); launched 10 April 1943; sponsored by Ens. Josephine D. Conningham, W-V(S), USNR (ibiblio transcription spells 'Connningham' - flagged in ev-06); commissioned 4 November 1943, Lt. R. R. Forrester, Jr., in command. After shakedown along the east coast, arrived Trinidad, British West Indies, 17 January 1944 for patrol and escort duty; January 1944 - March 1945 operated as convoy escort on nine regular runs from Recife, Brazil, to Trinidad, and engaged in ASW training with aircraft. Departed Trinidad 23 March [1945], arrived Miami 28 March; operated as a school ship out of the Naval Training Center, Miami, until transferred to China under the Lend-Lease Act 28 August [1945]; 'She serves the Chinese Navy under the name Yung Sheng.'

- Source discrepancies logged, not silently merged: (a) Build yard - DANFS prints 'American Shipbuilding Co., Cleveland, Ohio' (both mirrors agree, so the error is in the official text), while NavSource, uboat.net, Colton's Lorain yard table (hull #832), navalmarinearchive, and Wikipedia all read Lorain, OH - and sister Logic's own DANFS entry (AM-258) reads 'Lorain'; Lorain carried, 'Cleveland' flagged as a DANFS anomaly (the company was Cleveland-headquartered). (b) ROC end state - NavSource and uboat.net print ROC decommissioned 1 July 1972; Wikipedia's infobox prints 17 July 1972 while its own prose prints 1 July; Colton prints ROC 'struck 1970' while navalmarinearchive prints 'struck 1972' - 1 Jul 1972 carried for decommissioning; the ROC register-strike year is unresolved (1970 vs 1972); all sources agree fate unknown. (c) Propulsion - NavSource 'two 855shp Cooper Bessemer GSB-8 diesels + National Supply Co. single reduction gear, two shafts' vs Wikipedia '2 x ALCO 539 diesels, 1,710 shp, Farrel-Birmingham single reduction gear' (the AM-136..AM-165 block machinery fit - wrong for this Lorain hull) vs HyperWar stub 'diesel-electric engines, twin screws, 1,800 h.p.' (contradicted by the documented reduction gear) - NavSource carried; whether 855 shp is per-engine or total is unresolved (Fixity's NavSource page prints 1,710 shp for the same plant). (d) CO roster - NavSource 'Richard Charles Condon' vs uboat.net 'Richard Carlton Condon' - flagged, not resolved. (e) Sponsor spelling - ibiblio transcription 'Connningham' vs losthistory 'Conningham' - losthistory reading carried. (f) Spec variances - displacement 625 t (DANFS) vs 945 t full load (NavSource/navalmarinearchive) vs 915 t fl (HyperWar) vs 650d/650 t (Colton/Wikipedia); speed 14.8 vs 15 kts; draft 9'9" vs 10'; DANFS armament '1 3", 2 40mm., 6 20mm., 3 dcp., 2 dct.' vs NavSource's fuller wartime fit (twin 40mm, hedgehog, 4 K-guns, 2 dct). (g) U.S. decommission date - DANFS is silent; Wikipedia's infobox prints 28 August 1945 (same-day decommission-and-transfer); carried as the transfer date, not independently verified.

- Finding
- Era/design inference: this hull is a 1943-built steel Admirable-class minesweeper with a diesel direct-drive twin-screw plant (two Cooper Bessemer GSB-8 diesels, National Supply single reduction gear) - no boilers, no steam distribution. Its insulation load was materially lighter than a steam combatant's, but machinery and construction materials of the wartime era were commonly asbestos-containing: exhaust-system and muffler lagging, machinery gaskets and packing, electrical-cable insulation, accommodation/galley joiner insulation, winch and windlass brake linings, and deck compositions of the period. Exposure-relevant populations if any material was present: AmShip Lorain construction trades (Oct 1942 - Nov 1943); the U.S. wartime crew (design complement ~104) across shakedown, the Trinidad/Recife convoy-escort tour (Jan 1944 - Mar 1945), ASW training, and the Miami school-ship period; the transfer workforce at handover (Aug 1945); Republic of China Navy crews across 27 years of service as Yung Sheng (1945-1972 - including any ROC-side refits or maintenance, none of which are documented in located sources); and the disposal workforce if she was scrapped post-1972 (fate unknown).

No survey, specification, or material schedule naming AM-257 was located; establishes no asbestos content, quantity, location, condition, individual exposure, or causation. The diesel (non-steam) plant makes even era-level inference weaker than for steam vessels of the same era. The 27-year ROC service period and unknown final fate leave the hull's material history undocumented from 1945 onward.

Doctrinal context only for the vessel's type: claims arising from WWII-era 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 claims arising from service aboard a WWII diesel minesweeper would have faced; whether any such claim naming Lance exists is unverified this session.

The litigation surface of this hull is therefore unsearched at API depth, not searched-and-empty; Google-indexed site:courtlistener.com and site:va.gov queries returned no decisions naming the hull (hits were collisions - other hulls' BVA decisions, and unrelated 'AM-257' Bates-numbered pharma-litigation exhibit lists).

- Absence of a located public record does not prove absence of asbestos aboard - a 1943-built vessel is era-consistent with asbestos-containing materials even accounting for its lighter diesel insulation load, and the hull's 27-year ROC service plus unknown final disposition leave its material history undocumented. IMPORTANT: the CourtListener sweep did not run (throttled, shared quota) - 'no qualifying case located' reflects the non-litigation repositories and degraded Google-indexed queries only; a differently-phrased hull reference may exist in the opinion/docket indexes.

Muster rolls, deck logs, register entries, photo files, and transfer files are personnel/status/imagery/administrative records, not materials documentation.
