- Finding type
- vessel_history
- Finding
- NavSource's live YMS-307 hull page identifies this vessel as a YMS-1-class auxiliary motor minesweeper: laid down 26 October 1942 by Rice Brothers Corp., East Boothbay, Maine; launched 31 December 1943; completed 24 February 1944; struck from the Naval Register 19 February 1948; transferred to Turkey in May 1948 and named TCG Kirte (M 28); fate unknown. The page gives call sign Nan-Peter-Mike-William, states that YMS-307 served the navies of the United States and Turkey, and states that no DANFS history is currently available for YMS-307.

- Finding
- The National Archives Special List 44, by Ship Numbers, lists YMS-307 deck-log coverage from 28 February 1944 through 31 December 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, and the row carries no 'Other Name' or notes content.

- Finding type

- Finding
- NavalCoverMuseum's designation history for this hull independently records the sequence USS YMS-307 (commissioned-decommissioned, dates unknown), struck from the Naval Register 19 February 1948, then TCG Kirte (M-28) in Turkish naval service, transferred to Turkey May 1948, fate unknown. The museum holds one cover dated 23 June 1944, posted from another ship or station because YMS-307 had no post office - postal evidence of the hull in naval use during the war-diary and deck-log window.

- Finding
- The National Archives Catalog indexes 14 item-level war-diary records for USS YMS-307 in the series 'World War II War Diaries, Other Operational Records and Histories' under Records of the Office of the Chief of Naval Operations: monthly diaries spanning May 1944 through September 1945 (NAIDs 78458762, 78588755, 139736850, 134377936, 139830548, 139830544, 139847806, 139888074, 139958339, 139999521, 633449767, 101709791, 83566713, 77535034). The catalog metadata shows the items were scanned in the Fold3-NARA digitization collaboration; early-1944 monthly collection files (February and March 1944) also surface under a YMS-307 search.

[7]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.

- 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-307; no such hull-level file was retrieved for this record.

- Finding type

- Finding
- No qualifying ship-specific asbestos record was located in the public sources searched for YMS-307: the retained hull page, NARA deck-log finding aid, NARA war-diary catalog entries, NARA asbestos research guide, and GAO Navy-wide review do not provide a YMS-307 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, the indexed deck logs, and the Fold3-scanned war diaries remain open leads. This negative finding does not establish or defeat any exposure claim or legal eligibility.

No asbestos-qualified variant was run because no base query overflowed its 20-result page.
