   Official DANFS record for this hull: Admirable-class minesweeper (AM-250: dp. 530; l. 184'6"; b. 33'; dr. 9'9"; s. 15 k.; cpl. 104; a. 1 3"; 4 40mm.; cl. Admirable); name means 'Giving intimation or knowledge.' Steel-hulled minesweeper laid down 29 September 1943 by 'Savannah Machine & Foundary Co.,' Savannah, Ga.; launched '12 September 1943' (sic - precedes the keel laying; all other sources print 12 December 1943, flagged in ev-10); sponsored by Mrs. E. L. Smith; commissioned 26 June 1944, Lt. E. A. Comee in command. Shakedown and training at Little Creek, Va.; sailed 19 August 1944 for antisubmarine exercises off Bermuda; then regular duties as a convoy escort vessel between U.S. ports and Bermuda against the German submarine threat in the western Atlantic. Departed New York 5 February 1945 via the Canal Zone and West Coast ports to Cold Bay, Alaska, arriving 4 April 1945; 'With other minecraft, she was transferred to Russia under Lend-Lease the next day.' 'She was not returned after the war and was probably lost between 1948 and 1950.' No battle-star line.

   Limitations

   DANFS documents identity, builder, sponsor, dates, and service narrative - not materials or asbestos content. Two entry-level defects flagged in ev-10: the printed launch date '12 September 1943' is internally impossible (before the 29 September keel laying; 12 December 1943 carried from NavSource/uboat/Colton/Wikipedia infobox); and the closing lines ('transferred ... the next day' ~5 April 1945; 'probably lost between 1948 and 1950') are superseded by the NHC Project Hula appendix (transferred 22 May 1945 as T-273, scrapped 1960) and NavSource's 1947-48 whaler-conversion chain. Mirror transcription carried because the live NHHC page 404s and the Internet Archive was temporarily offline today - re-verification of the official text against a Wayback capture is an open lead.

   Finding

   Official NHC publication resolves this hull's transfer: appendix row 'Indicative (AM 250) | T-273 | [22 May ditto] | [1960-scrapped ditto]' - i.e., transferred 22 May 1945 under Project Hula, Soviet designation T-273, disposition 1960-scrapped. The same table assigns T-271 to Disdain (AM 222, also 22 May), T-272 to Fancy (AM 234, 21 May), T-278 to Nucleus (AM 268), T-279 to Palisade (AM 270, '1957-stricken'), T-280 to Penetrate (AM 271), T-281 to Peril (AM 272) - the correct cross-mapping that refutes the T-278/T-279 prints for this hull in Colton, NavalCoverMuseum, and the hazegray transcriber's note. Glossary: 'T (tralshik) - minesweeper.' Program context documented in the same volume: transfers staged at Cold Bay (Fort Randall); the U.S. sought return of 480 of 585 transferred combatants from 1947; the Navy ultimately accepted Soviet 'witnessed destruction' (59 vessels sunk near Murmansk and 20 near Nakhodka in 1956); a settlement on 343 vessels was reached in spring 1957; the comprehensive Lend-Lease settlement followed 18 October 1972 - the framework explaining why unreturned hulls like this one stayed nominally on the Naval Register until 1983.

   Finding

   Era/design inference: this hull is a 1943-44-built steel Admirable-class minesweeper with a diesel direct-drive twin-screw plant (two Cooper Bessemer GSB-8 diesels, National Supply Co. 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: Savannah Machine & Foundry construction trades (1943-1944); the wartime U.S. crew (design complement ~104) across an ~11-month commission spent on Little Creek training, Bermuda A/S exercises, U.S.-Bermuda convoy escort, and the Cold Bay transfer; and Soviet-era crews/conversion workers (1945-ca. 1960) - Soviet naval service, the 1947 whaler conversion, and the ~1960 scrapping are undocumented in located sources.

   Limitations

   Inference from documented design, machinery type, and construction era - NOT a hull materials record. No survey, specification, or material schedule naming AM-250 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 hull's entire post-May-1945 life in Soviet hands is uninstrumented as to materials.

   Limitations

   Absence of a located public record does not prove absence of asbestos aboard - a 1943-44-built vessel is era-consistent with asbestos-containing materials even accounting for its lighter diesel insulation load. IMPORTANT: the CourtListener sweep did not run (throttled, shared quota) - 'no qualifying case located' reflects the non-litigation repositories and degraded indexed queries only; a differently-phrased hull reference may exist in the opinion/docket indexes. The hull's entire Soviet career (1945-ca. 1960) and scrapping are undocumented, so no survey pathway exists in located sources. Does not establish presence or absence; does not establish or defeat any exposure claim or legal eligibility.

    Finding

    Source discrepancies logged, not silently merged: (a) Launch date - the DANFS transcription prints 'launched 12 September 1943,' internally impossible (precedes the 29 September 1943 keel laying it prints two clauses earlier) vs NavSource/uboat.net/Wikipedia infobox '12 December 1943' - December carried; whether the error is DANFS's own or the mirror's cannot be resolved while NHHC is 404 and IA offline. (b) Transfer/decommissioning dates - DANFS 'transferred to Russia under Lend-Lease the next day' after the 4 April 1945 arrival (~5 April) vs NavSource 'Decommissioned 5 April 1945' + 'Transferred ... 20 May 1945' vs uboat.net decommissioned/transferred 20 May vs Wikipedia decommissioned and transferred 22 May vs the NHC Project Hula appendix transfer date 22 May 1945 - the official appendix date carried; the ~5 April figure appears to be DANFS conflating arrival with transfer, absorbed into NavSource's decommissioning line. (c) Soviet pennant - T-273 (NHC appendix, NavSource, uboat.net, Wikipedia) vs T-278 (Colton yard row, navalmarinearchive mirror, hazegray DANFS transcriber's note) vs T-279 (NavalCoverMuseum) - T-278 and T-279 belong to sisters Nucleus (AM-268) and Palisade (AM-270) per the NHC appendix; T-273 carried. (d) Fate - 'sunk (mine) off North Korea May 1945' (Colton, NavalCoverMuseum, navalmarinearchive, hazegray transcriber's note) is REJECTED: internally impossible (precedes the 22 May transfer; the USSR did not enter the Pacific war until August 1945), contradicted by the NHC disposition '1960-scrapped' and by NavSource's documented 1947 Ministry of Mining whaler conversion and 1948 'Cyclone' rename. (e) DANFS closing 'not returned ... probably lost between 1948 and 1950' - era best-guess superseded by the NHC table and NavSource chain. (f) HyperWar stub prints 'Transferred to U.K. under Lend-Lease, 1944' - wrong recipient and year (USSR, 1945), and 'Diesel-electric engines, twin screws, 1,800 h.p.' - a reduction gear is mechanical drive, so 'diesel-electric' is a compilation slip (same slip flagged in batches 1169/1207/1209/1212/1216); NavSource's per-hull Cooper Bessemer GSB-8 + National Supply gear carried. (g) Propulsion - NavSource per-hull Cooper Bessemer vs Wikipedia class-generic infobox '2 x ALCO 539 ... Farrel-Birmingham' - NavSource carried; '1,710shp' per-engine vs total unresolved. (h) Builder name - DANFS prints 'Foundary'; NavSource 'Foundry'; uboat 'Machinery and Foundry' - 'Savannah Machine & Foundry' carried. (i) U.S. strike - NavSource 'Struck from the Navy Register 1 January 1983' (single-source) vs DANFS silence - the 1983 date is consistent with the NHC-documented return-negotiation framework under which unreturned hulls stayed nominally registered. (j) Displacement spread 530 t (DANFS) vs 945 t fl (NavSource) vs 625 t (HyperWar) vs 650 long tons (Wikipedia) vs 850d (Colton) - measurement bases unmerged. (k) 'Ordered 2 May 1942' (uboat.net) plausible against the block's 1942 contract year but secondary-only.

    Limitations

    Resolves publication-level discrepancies among the official DANFS text, the official NHC monograph, and secondary compilations, adopting the better-supported values and flagging the rest. For the Soviet career all sources below the NHC transfer line are secondary; the whaler chain rests on NavSource alone. NavSource's per-hull propulsion spec is preferred over class-generic infobox values because it names this hull's engine and gear. No asbestos content in any of these sources.

    litigation_documented

    Finding

    No case located names this hull (see negative_finding row and search_ledger - CourtListener sweep blocked this session). 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; no such claim naming Indicative was located.

    2019 decision

    Limitations

    Doctrinal context only - the cited case does not name or involve this hull, and DeVries addressed manufacturers' duty to warn for asbestos-containing components on Navy vessels generally. Classification note: a complaint's vessel list would be a pleading allegation, not a finding; no pleading naming this hull was located in the searches performed. 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's WWII muster-rolls series should cover this hull for her Jun 1944 - May 1945 commission - sibling Admirable-class hulls are demonstrably indexed, so coverage for AM-250 is expected but unconfirmed this session; (b) NARA RG 24 deck logs, Jun 1944 - May 1945 (an unusually short run, ~11 months); (c) NARA RG 19 BuShips records / General Information Books and the Navy contract file for the Savannah Admirable-class block (AM-246-258) - the plausible home of hull-level material schedules; (d) Project Hula Cold Bay transfer records for the 22 May 1945 group (NHC 1997 cites operational files) - the authoritative resolution of the decommission/transfer date splits; (e) Soviet-side records for T-273's Pacific Fleet service (1945-1947), the Ministry of Mining whaler conversion, Glavpromorrybprom 'Tsiklon' service (1948-), and the ~1960 scrapping - site and process undocumented in located sources; (f) Savannah Machine & Foundry yard records and successor-company archives (Aegis/Saylor/Intermarine/Colonial Terminals chain).

    Limitations

    Record-group mapping only - no box-level retrieval performed; existence of asbestos-specific documents for AM-250 is unknown until surveyed in person. Muster rolls, deck logs, transfer files, and disposal records are personnel/operations/disposal records, not materials documentation. Nothing in this row is an asbestos finding.
