[2]NavSource Online: Mine Warfare Vessel Photo Archive, YMS-2 - individual hull history and specifications [other_primary]

- Individual YMS-2 page: milestone list, specifications block, 1943 crewmember photograph caption, and DANFS-absence note
- Finding type
- vessel_history
- Finding
- NavSource identifies this hull as YMS-2, a YMS-1 Class Auxiliary Motor Minesweeper built by Henry B. Nevins, Inc., City Island, New York; laid down 7 March 1941; launched 28 January 1942; completed 9 April 1942; struck from the Naval Register 7 February 1947; transferred to the War Shipping Administration in April 1948; fate unknown. The page also records two 1943 photographs attributed to a YMS-2 crewmember and states that no DANFS history is available for YMS-2.

- Population
- Henry B. Nevins construction trades; U.S. Navy crew; later War Shipping Administration custody
- Limitations
- NavSource is a ship-history/photo archive rather than the underlying Navy registry or ship file. Its milestone and registry statements corroborate hull identity but do not document asbestos content, crew exposure, quantities, remaining material, or legal eligibility. 'Completed' is not treated as a commissioning date.

- YMS-2 officers and crew during the listed deck-log coverage
- Limitations
- This is a records-coverage entry, not a commissioning or decommissioning record and not evidence of asbestos aboard the hull. The list does not describe the log contents, operating locations, maintenance, materials, or individual exposure.

- YMS-1 class construction and operating personnel
- Limitations
- Class-level information is background only. It does not establish that any particular asbestos-containing product was installed on YMS-2, and it does not support a ship-specific exposure conclusion.

[5]Primary-source sweep of NARA, Navy/NHHC, NavSource, NVR, and official-source search results conducted for USS YMS-2 / YMS-2 [other_primary]
- Locator
- Research synthesis; see search_ledger rows sl-uss-yms-2-yms2-01 through -07
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, hazardous-material disclosure, insulation specification, or other primary record documenting asbestos aboard USS YMS-2 was located. No documented designation alias or matching alternate hull identity was located in the primary-source sweep.

- Population
- YMS-2 crew, construction trades, and later custodians
- Limitations
- A negative research finding is not proof that asbestos was absent. The public sources located establish history and records coverage but do not inventory materials; inaccessible or undigitized Navy work files could change the result. No class or construction-era inference is promoted to a hull-specific finding.

[6]Authenticated CourtListener helper sweep, interrupted by fleet-wide pacing stand-down [court_record]
- Locator
- Helper diagnostics: fleet-wide request budget momentarily spent; see search_ledger rows sl-uss-yms-2-yms2-04 through -07
- Finding type
- historical_record
- Finding
- The required four-query CourtListener sweep could not be completed: the exact-name opinion query and exact-name docket query were attempted through the authenticated helper, and the helper then returned its fleet-wide pacing stand-down. The hull-number opinion and hull-number docket queries were not run. No litigation conclusion is drawn from this incomplete sweep.

- Limitations
- This is a blocked/partial search result, not a zero-result finding. No asbestos variant was run because the base queries did not complete and the helper required a stand-down. The record does not establish or defeat exposure, causation, product identity, or legal eligibility.
