- NavSource is a volunteer secondary compilation, not a primary registry; dates and specs generally track Navy records but are not independently verified here against BuShips documents. Photo captions establish presence at Attu and San Francisco Bay - not specific operations or work performed. The NH 88411 launch-photo caption is dated 4 September 1943 while the timeline gives launch as 4 August 1943 - discrepancy unresolved (see gaps). Contains no asbestos content.

- Finding
- NARA's Special List 44 inventories U.S. Navy logbooks held in Record Group 24 (Bureau of Naval Personnel records, Entry 118). The by-ship-number list shows one coverage row for YMS-333: logbooks covering 12/2/1943 - 11/30/1945, matching her entire commissioned life (commissioned 2 Dec 1943) through late 1945. The logs are physical holdings; YMS-333 does not appear on NARA's 'Navy Deck Logs Available in the National Archives Catalog' online list, which covers only named vessels - numbered YMS hulls are listed only where renamed (e.g., bird-named AMS conversions).

Coverage ending 11/30/1945 while decommissioning was April 1946 may reflect the end of submitted logs or an inactivation period - not resolved. No asbestos content.

- The standard compiled reference for U.S. shipbuilding output lists under 'Built by Ballard Marine Railway': 'YMS 333 | US Navy | Minesweeper | 278d | 136 | 2-Dec-43 | Struck 1946' - independently confirming the builder, 136-ft length, 2 December 1943 delivery/completion, and 1946 striking. Yard program context from the same table: Ballard built BYMS 25-28 for the Royal Navy, YMS 326-333 (eight U.S. minesweepers, of which YMS-333 was the last), and PCS 1457-1458 subchasers on the same 136-ft wooden hull type. The yard was taken over by Pacific Fishermen in 1946.

- Compiled secondary reference tracking Navy contract deliveries - not a contract document itself. '278d' is deadweight tonnage, distinct from NavSource's 270-ton displacement figure; delivery date of 2-Dec-43 aligns with NavSource's completed-and-commissioned date. 'Struck 1946' is month-unspecific; NavSource's 29 October 1946 is the precise date. No asbestos content.

[5]Era inference built on: NavSource specifications for this hull (two GM 8-268A diesels, no steam plant); YMS-1-class type documentation (wooden-hulled motor minesweeper, 136 ft); GAO HRD-80-2 Navy asbestos-use documentation (see ev-05) [other_primary]

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel motor minesweeper built in 1943 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small diesel craft of this type and period were engine and exhaust-system lagging, gaskets, valve packing, electrical insulation, and asbestos-cement or fire-resistive sheet around machinery spaces. As a diesel vessel with no boilers or steam turbines, the boiler/steam-line lagging pathway of steam ships does not apply, and her small wooden hull implies lower asbestos loading than steam combatants - but confined machinery-space exposure dynamics still apply to engine room ratings.

- A named veteran is documented aboard this hull: Fred A. Barnowsky (b. 18 Feb 1923, Scobey, MT; d. 15 Jul 2008, Kalispell, MT) 'entered the US Navy where he served aboard YMS-333, a Navy Yard Mine Sweeper. After the war Fred returned to jumping at Missoula from 1946-56.' A Forest Service rookie at Missoula in 1942, he served aboard during WWII and returned to civilian smokejumping in 1946.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming USS YMS-333 / YMS-333 was found in the public sources searched (see search_ledger). All four CourtListener base queries ran: exact-name opinion returned 2 OCR-noise name collisions; the other three base queries overflowed (counts 1040 / 93 / 7288) via non-phrase token matching with all sampled results non-qualifying; three asbestos-qualified variants (sanctioned by the overflows) returned counts 8 / 673 / 144 - every reviewed hit was OCR noise or a generic asbestos docket containing no 'YMS' string or vessel reference. No DANFS entry exists; no NVR entry exists (disposed pre-1987); no marketing-source 'asbestos aboard' pages specific to this hull were located. No designation alias exists - struck in 1946, she never received the 1947 AMS naming.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-consistent presence of asbestos-containing materials in machinery insulation, gaskets, packing, and electrical systems cannot be ruled out. Physical deck logs exist at NARA (RG 24) but are undigitized; builder's records and WSA disposal files are undigitized leads. Does not establish or defeat any claim of exposure or legal eligibility.
