- Finding
- YMS-1 class auxiliary motor minesweeper: laid down 18 June 1942 by Colberg Boat Works, Stockton, CA; launched 27 October 1942; completed 30 April 1943; sunk by mine 1 October 1944 in Zowariau Channel, Ulithi, Caroline Islands at 09 deg 52' N, 139 deg 37' E; struck from the Naval Register 14 October 1944.

- Study period
- 1942-1944
- Limitations
- NavSource is a volunteer-maintained reference, not a government publication; its timeline agrees with NHHC on the loss date/cause but its specification block conflicts with the HyperWar class template (displacement 270 t vs 320 t full; draft 8' vs 6'1"; speed 15 vs 13 kts; complement 32 vs 33; 1,760 shp total vs 500 hp) - unreconciled, see gaps. Establishes identity and loss only; contains no asbestos information. 'Completed' vs 'commissioned' wording for 30 April 1943 is unresolved.

[4]National Archives Catalog, file unit NAID 193006526, 'YMS-385, 4/30/43-8/31/44' (National Archives at College Park; 94 digital objects, images provided by Ancestry) [other_primary]
- Locator

- Finding type
- historical_record
- Finding
- NARA holds a digitized log series for YMS-385 covering 30 April 1943 through 31 August 1944 - the vessel's entire commissioned life except its final month. The Catalog record carries 94 page images (Ancestry partnership scans) and is physically held at NARA College Park. This matches the deck-log coverage inventoried in NARA Special List 44 as given in the batch assignment (4/30/1943-8/31/1944).

- Limitations
- Inventory-level record: the log page images were located but their contents were not reviewed this session, so nothing in them (including any material or maintenance references) is asserted here. Coverage ends 31 August 1944; the final month (September 1944, including the sinking) is not in this series - whether a September log ever reached NARA is unknown. The batch assignment's pinpoint 'Special List 44, PDF page 120' could not be re-verified live: archives.gov publishes only the named-vessels portion online, and the full 1978 volume scan on Internet Archive is access-restricted (HTTP 401); the Catalog record above independently confirms the same coverage dates.

- YMS-385 page, specification block and loss line
- Finding type
- vessel_history
- Finding
- HyperWar's YMS-385 page carries the generic YMS-1 class template - 320 t (full), 136', beam 24'6", draft 6'1", 13 kts, one 3"/50 and two 20mm, complement 4 officers + 29 crew, diesel engines on twin screws rated 500 hp - and a loss line reading '10 Oct 1944; Sunk by mine at 09 deg 52' N, 139 deg 37' E (western Caroline Islands, near Mog Mog)'.

- Limitations
- The specification block is the generic class template, not a hull-specific record. The loss-line date '10 Oct 1944' conflicts with NHHC and NavSource (both 1 October 1944) and is treated as a transcription error; only the position (which matches NavSource) is consistent with other sources. Contains no asbestos information.

[6]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 October 1979) - product page Highlights [gao]
- Locator
- Product page Highlights section
- Finding type
- gov_survey
- Finding
- GAO reviewed Navy efforts to protect workers from asbestos exposure at the Long Beach and Norfolk Naval Shipyards, covering the use of asbestos in Navy ships, the cost of removing it, and compensation programs. The Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for repairs; in 1979 this was modified to include selectively replacing asbestos insulation in high-maintenance areas.

- Limitations
- Program-level context from 35 years after this vessel was sunk. GAO fieldwork yards were Long Beach and Norfolk - not this vessel's builder. The report does not name YMS-385 or the YMS type and establishes only that asbestos insulation was used in Navy ships of the era as a general matter; it cannot establish whether any asbestos-containing material was installed aboard this small wooden-hulled diesel minesweeper. gao.gov blocks automated curl fetches (HTTP 403, standing since batch-01); the Highlights text was verified live via a browser-grade fetch 2026-10-05.

[7]Batch-9020 search ledger (this record): NavSource; NHHC casualties list; NARA Catalog NAID 193006526; HyperWar class page; GAO HRD-80-2; CourtListener API v4 (four base queries); NVR; shipyards.json cross-check; secondary web survey [other_primary]

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, museum or memorial documentation, or docketed litigation naming YMS-385 was found in the sources searched (see search_ledger). No class-level asbestos document for the YMS-1 type was located either. Secondary web content asserting asbestos aboard YMS-class vessels exists only as law-firm marketing listicles without primary sourcing - excluded by source policy.

- Limitations
- Absence of a located record does not prove absence of asbestos aboard: era-typical applications on a 1942 diesel minesweeper (exhaust lagging, gaskets, valve packing, electrical insulation) have not been ruled in or out by any source reviewed. The vessel sank in 1944, so there is no extant hull to survey and no abatement record would be expected. CourtListener base queries were attempted this session; their status is recorded in the search ledger. Does not establish or defeat any claim of exposure or legal eligibility.
