   Official DANFS record for this hull: Admirable-class minesweeper (dp. 530; l. 184'6"; b. 33'; dr. 9'9"; s. 15 k.; cpl. 104; a. 1 3", 4 40mm.). Laid down 19 January 1944 by Savannah Machine & Foundry Co., Savannah, GA; launched 6 February 1944, sponsored by Miss Thayer C. Allen; commissioned 18 September 1944, Lt. H. H. Silliman in command. Shakedown in Chesapeake Bay; steamed to Casco Bay, Maine, for training 24 November 1944; additional drills out of Norfolk, then assumed duties there as towing ship for aircraft targets and as an experimental minesweeper - remaining on that duty through the end of the war. Reported 21 September 1945 to the Mine Warfare School at Yorktown, VA, as a training ship. Decommissioned 7 August 1946 and joined the Atlantic Reserve Fleet at Orange, TX. Reclassified MSF-254 on 7 February 1955; struck from the Navy List 1 May 1962; sold to Mexico 30 August 1962 (transcriber's note: served Mexican Navy as DM-18).

   DANFS documents identity, builder, dates, and the service narrative - not materials or asbestos content. The narrative establishes an entirely CONUS/Atlantic career (Chesapeake Bay, Casco Bay, Norfolk, Yorktown): no combat-theater deployment is recorded, which contradicts the 'served in the Pacific' lead line on Wikipedia - flagged in ev-06.

The build-date table gives '19 Jan 44 / 6 Feb 44 / 18 Sept 44' for AM-254 - matching DANFS exactly.

   Source discrepancies logged, not silently merged: (a) Theater of service - Wikipedia's lead claims 'She served in the Pacific during World War II,' but DANFS's own narrative is entirely CONUS/Atlantic (Chesapeake shakedown, Casco Bay training, Norfolk towing/experimental duty through end of war, Yorktown Mine Warfare School); no Pacific service is documented anywhere - DANFS carried, Wikipedia lead flagged as error. (b) Propulsion - Wikipedia's class-generic infobox prints '2 x ALCO 539 diesel engines ... Farrel-Birmingham single reduction gear'; official NAVSHIPS 250-011 (ditto chain to head row HAZARD AM-240 'C-B GSB-8 / Nat. Sup.') and NavSource both give Cooper-Bessemer GSB-8 / National Supply - official data carried; same ALCO misattribution flagged for sisters in batches 1219/1220/1221. (c) Builder name - DANFS 'Savannah Machine & Foundry Co.'; NavSource/Colton 'Savannah Machine and Foundry Co.'; uboat.net 'Savannah Machinery and Foundry Co.'; HyperWar per-hull page 'Savannah Foundry' - majority form carried. (d) Propulsion label - HyperWar class block and per-hull page print 'Diesel-electric engines, twin screws, 1,800 h.p.'; the documented reduction gear is mechanical drive, so 'diesel-electric' is a compilation slip (same slip flagged in batches 1169/1207/1212/1220) - NAVSHIPS/NavSource carried. (e) Displacement - DANFS 530; NavSource 945 t (fl); Colton 850d; HyperWar class block 625 t - different measurement bases, unmerged; DANFS carried in the record narrative. (f) Speed - DANFS 15 kts vs NavSource 14.8 kts - DANFS carried. (g) Mexican naming timeline - Colton's disposition column reads 'To Mexico 1962 as General Ignacio Zaragoza (C 60), active,' merging the 1962 transfer (as DM-18) with the 1994 rename and showing stale 'active' status; Wikipedia/seaforces/NavalCoverMuseum date the Zaragoza rename to 1994 and the stricken to 2001-07-16 - flagged in ev-05. (h) Decommission planning quirk - NavSource footnote: the NVR of 1 Jan 1949 lists 'plan for decommissioning and placing in reserve as December 1945' vs the actual 7 Aug 1946 - register-planning artifact, not a date conflict. (i) CO handover - NavSource prints a gap (Flynn to 1 Nov 1945; Curtis from 15 Jan 1946); uboat.net prints Flynn to 'Nov 1945' - minor variance, unmerged.

    Finding

    Era/design inference: this hull is a 1944-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 1944 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: Savannah Machine & Foundry construction trades (1944); the wartime U.S. crew (design complement ~104) across the Chesapeake shakedown, Casco Bay training, and the Norfolk experimental/towing assignment; Mine Warfare School trainees and staff (Sep 1945 - Aug 1946); Atlantic Reserve Fleet lay-up and maintenance personnel at Orange, TX (1946-1962); and the Mexican Navy crew of DM-18/Zaragoza (1962-2001).

No survey, specification, or material schedule naming AM-254 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. Her CONUS-only career means no combat damage and no forward-area repair availabilities; Mexican-service maintenance (1962-2001) is undocumented in located sources.

    Absence of a located public record does not prove absence of asbestos aboard - a 1944-built vessel is era-consistent with asbestos-containing materials even accounting for its lighter diesel insulation load. The hull survives only in Mexican-disposal records: stricken 2001, ultimate fate unreported, so no present-day survey pathway exists.

    Limitations

    Record-group mapping only - no box-level retrieval performed; existence of asbestos-specific documents for AM-254 is unknown until surveyed. War diaries, deck logs, and muster rolls are operations/personnel records, not materials documentation. The Mexican half of this hull's life (39 years) is undocumented in U.S. sources. Nothing in this row is an asbestos finding.
