- Finding type
- vessel_history
- Finding
- NavSource's live YMS-298 hull page identifies this vessel as a YMS-1-class auxiliary motor minesweeper: laid down 10 February 1943 by Tacoma Boat Building Co., Tacoma, Washington; launched 16 June 1943; completed 22 October 1943; struck from the Naval Register 3 July 1946; transferred to the War Shipping Administration in January 1948; fate unknown. The page gives call sign Nan-Peter-Dog-George and states that no DANFS history is currently available for YMS-298.

- NavSource is a specialist photographic/archive compilation rather than a Navy register or DANFS entry; the page does not give a formal commissioning date, detailed service narrative, or final post-WSA disposition. It contains no asbestos or material-content statement.

[3]National Archives, Special List #44, by Ship Numbers, PDF entry for YMS-298 [other_primary]

- Finding type
- historical_record
- Finding
- The National Archives Special List 44, by Ship Numbers, lists YMS-298 deck-log coverage from 28 October 1943 through 30 June 1945. The entry is an archival inventory of surviving or cataloged log coverage; it does not assert that those dates are the commissioning or decommissioning dates of the vessel.

[5]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (18 October 1979) [gao]

- GAO product-page highlights; full report PDF was not directly retrievable in this session
- Finding type
- gov_survey
- Finding
- GAO's 1979 Navy review addressed asbestos use in Navy ships, the cost of removing asbestos from Navy ships, and Navy protection of shipyard workers. Its published summary states that the Navy's 1975 policy was to remove and replace non-asbestos materials only when damaged insulation had to be removed for necessary repairs, with a 1979 modification for selected high-maintenance areas.

- Navy shipyard workers and Navy vessels covered by the 1979 review
- Limitations
- Program-level Navy evidence, not a YMS-298 record. It supports era context only and does not prove installation, location, condition, disturbance, quantity, exposure, or causation aboard this hull. Direct automated access to the GAO page/PDF returned HTTP 403; the indexed official product summary was used.

[6]National Archives, Researching Asbestos aboard US Naval Vessel up through 1961 [other_primary]

- Official guided-topic page: RG 19/RG 143 research pathways
- Finding type
- regulatory
- Finding
- NARA's official research guide identifies RG 19 Bureau of Ships records, ship/general information books, specification files, and engineering drawings as the archival pathways for researching asbestos and related ship material questions for U.S. Navy vessels through 1961. These records are the appropriate next archival lead for YMS-298; no such hull-level file was retrieved for this record.

[7]Batch-8923 source review: NavSource YMS-298; NARA Special List 44; NARA asbestos research guide; GAO HRD-80-2 [other_primary]
- Locator
- Search ledger rows sl-uss-yms-298-yms298-01 through -09
- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located in the public sources searched for YMS-298: the retained hull page, NARA deck-log finding aid, NARA asbestos research guide, and GAO Navy-wide review do not provide a YMS-298 asbestos survey, abatement contract, hazmat disclosure, material schedule, product identification, or adjudicated exposure finding. Ship-specific asbestos status is therefore unknown.

- Limitations
- A failure to locate a public record does not prove absence of asbestos aboard the hull. Undigitized RG 19/RG 143 records remain an open lead. This negative finding does not establish or defeat any exposure claim or legal eligibility.

[8]CourtListener authenticated search helper status (cl-auth-search.py); fleet-wide pacing budget unavailable during this session [court_record]
- Locator
- Required base query attempted: exact-name opinion, query "USS YMS-298"; helper did not return a result before the pacing stand-down
- Finding type
- litigation_documented
- Finding
- The required authenticated CourtListener litigation sweep could not be completed: the first base query was submitted through cl-auth-search.py but remained held by the fleet-wide pacing limiter without returning a result, so the remaining three base queries were not run. No asbestos-qualified variants were run. This record therefore makes no negative finding about asbestos litigation involving YMS-298.
