- PDF p. 117, ship-number index, YMS-242 row
- Finding type
- historical_record
- Finding
- NARA Special List 44 lists Navy deck-log coverage for YMS-242 from 1943-03-27 through 1945-03-31. These are listed log-coverage dates, not commissioning or decommissioning dates.

- 1943-03-27 to 1945-03-31 (listed deck-log coverage)
- Limitations
- The finding aid establishes listed log coverage for this hull; it is not the log content and does not establish construction, commissioning, decommissioning, asbestos materials, individual exposure, or present-day condition. The underlying logs were not examined.

[3]Dictionary of American Naval Fighting Ships, Harkness (YMS-242) [nhhc_danfs]

- DANFS Harkness history, conversion and postwar-service paragraphs
- Finding type
- vessel_history
- Finding
- DANFS identifies Harkness as YMS-242 and states that, after conversion by South Coast Shipbuilding Co., Newport Beach, California, she was named Harkness and reclassified AGS-12 on 24 March 1945. It records later reclassification as AGSC-12 at Miami on 29 July 1946, decommissioning on 22 September 1950, conversion at Brooklyn Navy Yard and reclassification as AMCU-12 on 18 August 1951, recommissioning on 5 September 1951, reclassification as MHC-12 on 1 February 1955, decommissioning on 2 April 1958, and striking on 1 November 1959.

- Limitations
- DANFS is a vessel-history source, not an asbestos survey or material specification. It does not establish asbestos presence, products, quantities, removal, individual exposure, causation, or legal eligibility. Direct automated retrieval returned HTTP 404, but the official page and its summary were verified live through the available web index; no archival substitute is presented as a live source.

- Finding
- The live NavSource individual-history page corroborates the hull identity and the sequence YMS-242, AGS-12/Harkness, AGSC-12, AMCU-12, and MHC-12.

- NavSource is used only for hull-identity corroboration, not as authority for asbestos content, service dates, construction facts, condition, exposure, or legal eligibility. The exact navsource.net URL returned HTTP 200 when verified on 2026-10-04.

- Locator
- Beginning Research; RG 19 discussion; General Information Books; minesweeper and minelayer GIB entry
- Finding type
- regulatory
- Finding
- NARA's official guide states that research into asbestos in U.S. Navy materiel from 1941 through 1961 is complex and identifies RG 19 Bureau of Ships correspondence, minesweeper/minelayer General Information Books, specifications, hull engineering drawings, and inspection records as potentially responsive sources for vessel-specific research.

- Population
- U.S. Navy vessels and shipyard/crew research within the guide's 1941-1961 scope
- Limitations
- This is a research path for Navy-era records, not a Harkness/YMS-242 material record. The referenced records were not retrieved or examined; the guide neither proves nor disproves asbestos aboard this hull.

[6]Batch-8880 public-source and CourtListener search ledger for USS Harkness/YMS-242 (see search_ledger) [other_primary]
- Locator
- search_ledger rows sl-uss-yms-242-yms242-01 through -07
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, materials specification, or product identification was located in the public official sources searched. CourtListener queries did not return results because the authenticated helper remained awaiting the fleet-wide pacing token; litigation status is incomplete, not negative.

- Population
- Public official-source records and CourtListener indexed opinions/RECAP dockets
- Limitations
- Failure to locate a public material record does not prove asbestos absence or presence. Each of the four required CourtListener base-query invocations was started through the authenticated helper, but none obtained a pacing token or made an HTTP request before the execution window ended; therefore no query result, hit classification, or litigation negative finding is asserted. No asbestos-qualified variants were run.
