- NavSource record for this hull: YMS-1 Class Auxiliary Motor Minesweeper; laid down 16 March 1942 as YMS-226 by Frank L. Sample, Jr., Boothbay Harbor, ME; launched 31 August 1942; completed 16 January 1943; transferred to France 2 October 1944 and named 'Asphodere' (D 314) [sic - French archive spelling is ASPHODELE]; sold to France 21 March 1949; struck from the Naval Register 28 April 1949; reclassified D-03 and M-643; decommissioned 11 February 1969; fate unknown. Page states 'There is no DANFS history available for YMS-226.' Call sign Nan-Charlie-Mike-King. Specifications: displacement 270 t; length 136'; beam 24' 6"; draft 8'; speed 15 kts; complement 32; armament one 3"/50 dual-purpose mount, two 20mm mounts, two depth-charge projectors; propulsion two 880 bhp General Motors 8-268A diesel engines, Snow and Knobstedt single-reduction gear, two shafts.

- Limitations
- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates generally track official records but contain no primary citation per item. Several spec-block figures conflict with other sources (complement 32 vs class-block 33; displacement 270 vs 278/320; speed 15 vs 12 kts designed - see gaps). Contains no asbestos content. The 'Asphodere' spelling is a transliteration error; French sources give ASPHODELE/Asphodèle.

- Finding
- The National Archives finding aid records U.S. Navy deck logs for YMS-226 covering 1/25/1943-10/2/1944 (PDF page 116 of the ship-number index, verified by direct text extraction). The coverage window begins nine days after her 16 January 1943 completion and ends on the exact date of her transfer to France - consistent with continuous U.S. Navy custody and operation from January 1943 through 2 October 1944, and inconsistent with any 1943 British transfer.

- Finding type
- historical_record
- Finding
- The French Navy's official archive directory entry for this hull (2C 150) confirms the identity chain in its own words: 'Type: Dragueur YMS ex "D314" ex "YMS 226"'; 'Origine: U.S.A.'; 'Date de mise sur cale: 1942'; 'Date d'admission au service actif: 1er octobre 1944 (France)'; 'Date de desarmement: Condamne en 1968'. The alphabetical index lists her as 'Dragueur ASPHODELE (1944-1963)' - i.e., ~19 years active in French minesweeping service before her servitude-role years. The entry also preserves a commanding-officers list: E.V.1 Rondeland (1944-1946), L.V. Coursaud (1946-05/11/1947), L.V. Bardon (05/11/1947-13/03/1948), E.V.1 Briel (13/03/1948-13/03/1950), C.C. Labescat (from 13/03/1950), with successors listed through 1954.

- Finding
- A second, independent SHD record: the technical-dossier series (AA 5I, dossiers techniques des batiments / avaries 1924-1977) catalogs ASPHODELE - again explicitly as an 'ancien dragueur americain type YMS' - for 1964-1967, when she served in the 'batiments de servitude / annexe ecole navale' category (auxiliary craft annexed to the Ecole navale). Consistent with the 2C 150 index's 1944-1963 active-minesweeper span: after ~1963 she continued in servitude/annex use until condemned in 1968.

- Class-level documentation for the YMS-1 type: 'The wood-hulled YMS proved to be one of the U.S. Navy's more durable and versatile types'; 561 built at 35 yacht yards (12 East Coast, 19 West Coast, four Great Lakes) rather than larger shipyards; first-of-class YMS-1 designed by and built at Henry B. Nevins, Inc., City Island, NY; class characteristics 136' overall, 24' 6" beam, ~320-ton displacement, designed speed 12 knots, General Motors 8-268A diesel engines on two shafts, one 3"/50 dual-purpose and two 20mm mounts. BYMS accounting scheme: BYMS-1 to BYMS-80 (built for Britain under Lend-Lease) received British pennants BYMS-2001 to BYMS-2080; seventy later BYMS originally built as USN YMS bore hull numbers 137-284 'with their original U.S. Navy numbers' on the Navy List, and transferred hulls received Royal Navy J-series pennants (e.g., sister YMS-225 'to Great Britain as HM J-1025').

- Finding
- CORRECTION: secondary shipbuilding tables (Colton's Shipbuilding History and the Naval Marine Archive mirror) carry 'To Britain 1943 as BYMS 2226' for this hull. That claim is contradicted by the primary record and by the cited compilations' own pennant data: (1) NARA Special List 44 shows U.S. Navy deck logs for YMS-226 running continuously 1/25/1943-10/2/1944 - a hull transferred to Britain in 1943 would not generate U.S. Navy deck logs through October 1944; (2) NavSource's YMS/BYMS index explicitly lists 'BYMS-2226 - BYMS-2228 - Pennant numbers not used' (the sister hulls that did go to Britain are individually annotated 'to Great Britain as HM J-10xx' - YMS-226 carries no such annotation); (3) NavSource, uboat.net, and the French SHD directory all show the direct U.S.-to-France chain (SHD: 'Dragueur YMS ex D314 ex YMS 226', admitted to French service 1 October 1944). The BYMS-2226 entry is best explained as a reserved-but-never-executed wartime allocation or a copy-forward error in the yard table.

- Limitations
- Corrects a circulating attribution error, not a material claim. The residual possibility of a paperwork allocation (pennant reserved on paper, never assigned in service) cannot be excluded - NavSource records the pennant as 'not used', which covers both cases. Shipbuilding-history data otherwise tracks the documented French transfer correctly (Asphodele D 314, struck 1969).

- Finding type
- asbestos_application
- Finding
- A wood-hulled diesel-driven auxiliary motor minesweeper built 1942-43 at a small Maine yacht yard sits inside the Navy's documented asbestos-use era. Era-standard asbestos applications aboard a diesel minesweeper of this type and period were diesel exhaust lagging, gaskets, valve/stem packing, electrical insulation, fireproof joiner and headlining board in accommodation spaces, and brake/clutch linings on winches and sweep gear. As a diesel vessel she carried no steam plant - the boiler/steam-line lagging pathway of steam vessels does not apply - and her wooden hull reduced, though it did not eliminate, the insulated-surface and fireproof-joiner scope relative to steel steam vessels.

Product names are normalized era terms; no manufacturer attribution for this hull. A small wooden minesweeper plausibly carried less asbestos than a steam combatant, but no source quantifies this.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or verified litigation naming USS YMS-226 / YMS-226 / Asphodele was found in the public sources searched (see search_ledger). CAVEAT: CourtListener could not be queried this session - the fleet-wide pacing budget (token bucket ~58/hr shared across all sessions) never yielded a request token across ~90 minutes of spaced attempts, including a 20-minute token-watch window; logged as blocked in search_ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard minesweepers' material is law-firm marketing content (mesothelioma.net, asbestos.com, mesotheliomaveterans.org, mesothelioma.com listicles) asserting asbestos without hull-level primary sourcing - excluded by source policy.

- Absence of a located public record does not prove absence of asbestos aboard - era inference for a 1942-43 naval vessel remains reasonable, and the litigation repository search is a genuine open gap (pacing-blocked, not run). Undigitized leads: the RG 24 deck logs themselves, any Sample yard work packages, the SHD 2C 150 dossier (Brest), and the SHD technical dossier AA/375/I/5/236/4 (Chatellerault, 1964-67).
