- Finding type
- vessel_history
- Finding
- NavSource identifies this hull as YMS-139, a YMS-1-class auxiliary motor minesweeper: laid down 4 January 1943 by Astoria Marine Construction Co., Astoria, Oregon; launched 19 May 1943; completed 24 June 1943; transferred to the Soviet Union 19 July 1945 and reclassified T-594; assigned to the Soviet Pacific Fleet 1 August 1945; placed out of service 1 September 1955 and scrapped. The page gives call sign Nan-William-Vice-William, two 880-bhp General Motors 8-268A diesel engines, Snow and Knobstedt single-reduction gear, two shafts, and complement 32; it states that no DANFS history is available for YMS-139.

- Limitations
- NavSource is a volunteer compiled history, not a primary Navy registry or transfer instrument. It supports hull identification and reported milestones but contains no asbestos, maintenance, or exposure documentation and does not state a U.S. commissioning date. The T-594 designation is reported for post-transfer Soviet service, not established here as a U.S. designation alias.

- Finding type
- historical_record
- Finding
- NARA Special List 44 indexes U.S. Navy deck-log coverage for YMS-139 in two intervals: 17 July 1943 through 31 May 1945, and 1 July through 18 July 1945. The latter indexed interval ends one day before NavSource's reported 19 July 1945 transfer to the Soviet Union.

- Limitations
- This is a finding-aid index, not the logbooks: it establishes indexed log coverage, not log contents, commissioning, decommissioning, location, operations, materials, or exposure. The indexed gaps before 17 July 1943 and during June 1945 are not explained by this source. The 19 July transfer date comes from NavSource, not from Special List 44.

- NARA deck-log guidance: permanent-record rule, World War II exception, definition of deck logs, and 1941-and-later College Park holdings
- Finding type
- historical_record
- Finding
- NARA explains that deck logs are chronological records of daily activities, that only commissioned-ship deck logs are normally retained permanently (with a World War II partial exception for in-service vessels), and that logs dated 1941 and later are generally held at the National Archives in College Park. This is the access path for the YMS-139 intervals indexed in Special List 44.

- Finding type
- regulatory
- Finding
- NARA identifies asbestos in U.S. Navy materiel from 1941 through 1961 as a complex research topic and describes the records path for a hull-specific inquiry: RG 19 Bureau of Ships correspondence filed by hull designation, class, or type; builder contract correspondence in QM files; ship/general information books; specification files; and engineering drawings. For this hull, those are leads for a search under YMS139, the YMS class, and Astoria Marine Construction Co.

- Limitations
- Research-pathway guidance, not a finding that YMS-139 contained asbestos. None of the described RG 19 records were retrieved or reviewed for this hull, so the source does not establish products, quantities, locations, remaining material, individual exposure, causation, or legal eligibility.

- NavSource YMS/BYMS index introduction and class specification block
- Finding type
- asbestos_application
- Finding
- The NavSource class index describes YMS vessels as wooden-hulled auxiliary motor minesweepers, with YMS-135 and later one-stack variants; its class specification block lists General Motors 8-268A diesel engines, two shafts, 880 designed shaft horsepower, 136-foot length, and complement 33. This supplies type context for YMS-139's reported diesel machinery and confirms that class context does not supply a boiler or turbine system.

- YMS-class construction trades and crews
- Limitations
- Class-level compiled reference only. It does not document asbestos-containing material or any particular component aboard YMS-139, and it cannot be used to infer ship-specific presence, quantity, condition, exposure, or causation. Individual-page versus class specifications differ (e.g., complement 32 vs. 33); the individual-page figure is carried as reported, not reconciled here.

[7]CourtListener authenticated API v4 base queries via /Users/charlesfletcher/devin-prompts/cl-auth-search.py fleet helper, 2026-10-04 [court_record]

- Helper output: exact-name docket query HTTP 200, count 0; authenticated-request diagnostics without completed result for the other three required base queries
- Finding type
- litigation_documented
- Finding
- The required authenticated CourtListener exact-name docket query, "USS YMS-139" (type=r, limit 20), returned HTTP 200 with count 0. The exact-name opinion and the hull-number opinion and docket base queries were submitted once through the same authenticated helper but did not return a result within the helper execution window; no asbestos-qualified variants were run because no completed base query overflowed 20 results.

- Limitations
- This is an incomplete sweep, not a no-litigation conclusion. Only one of four base queries returned an API result, and its zero result applies only to the exact-name docket search. No anonymous, raw, or v3 CourtListener request was made; no repeat query was made. No qualifying litigation hit was retrieved, so no litigation stage is assigned.

- Finding type

- Limitations
- Absence of a located public record does not establish absence of asbestos aboard. NARA identifies undigitized RG 19 correspondence, information books, specifications, and drawings as the appropriate next research path; YMS-139 deck logs were not reviewed. CourtListener coverage is incomplete, so litigation status remains open on three required query axes.
