- Finding
- NARA's official Special List 44 inventory lists deck logs for YMS-46 from 1942-07-08 through 1946-05-15. The entry establishes the existence and indexed coverage span of log records for this hull.

- YMS-46 crew during the indexed log coverage
- Limitations
- An inventory entry, not the deck-log contents. The coverage dates are not asserted to be commissioning, decommissioning, transfer, or disposal dates; whether the underlying logbooks are digitized was not established. Deck logs are operational/personnel records and this entry contains no asbestos or materials finding.

- vessel_history
- Finding
- NavSource's live YMS-46 timeline identifies the hull as laid down 24 June 1941 by Wheeler Shipbuilding Corp., Brooklyn; launched 30 April 1942; completed and commissioned USS YMS-46 on 20 June 1942; struck 10 June 1947; transferred to the War Shipping Administration in April 1948; registered in 1949 to S. S. Seafoods, Inc. as fishing boat Leonardo I; sold in 1950 and operated under the Mexican flag; fate unknown. Its specification block states 270 tons, 136 feet length, 24 feet 6 inches beam, 8 feet draft, 15 knots, complement 32, one 3-inch/50 mount, two 20 mm mounts, two depth-charge projectors, and two 880-bhp General Motors 8-268A diesels through Snow and Knobstedt single-reduction gear on two shafts.

- Population
- Wheeler Shipbuilding construction trades (1941-42); U.S. Navy crew (at least the NARA-indexed 1942-46 period); civilian crews after reported sale
- Limitations
- NavSource is a live volunteer secondary compilation, not an official registry. It supports the stated identity and timeline lead only; it contains no asbestos, survey, abatement, product, crew-exposure, or causation evidence. The page states no DANFS history is currently available for this hull.

- Locator
- GAO product URL; direct live request returned HTTP 403
- Finding type
- gov_survey
- Finding
- GAO's 1979 report Navy Efforts To Protect Workers From Asbestos Exposure is retained only as Navy-wide historical context for a Navy vessel constructed in 1941-42. No detailed proposition from the report is attributed because the live GAO product page returned HTTP 403 during this research pass.

- Limitations
- Navy-wide program context, not a hull-specific record; the full report was not retrieved. It cannot establish asbestos installation, product identity, quantity, condition, exposure, or causation aboard YMS-46.

[5]CourtListener authenticated API v4 helper sweep and official-source research ledger, 2026-10-05 [other_primary]
- Locator
- search_ledger rows sl-uss-yms-46-yms46-04 through sl-uss-yms-46-yms46-07
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, product identification, or qualifying litigation result was obtained in this research pass. The required CourtListener exact-name opinion and docket searches were initiated through the authenticated v4 helper, but the helper reported the fleet-wide pacing budget unavailable before any results were returned; the remaining base queries were not sent after that stand-down.

- Limitations
- This is not a conclusion that no litigation or asbestos exists. CourtListener did not return a result page for a completed query, and the hull-number searches were not sent after the authenticated helper directed non-CourtListener work. No asbestos-qualified variants were authorized because no base query returned a 20-result overflow. Public-source absence does not establish absence aboard the hull or legal eligibility.

- NARA deck-log guidance, RG 24 and 1941-and-later College Park holdings; paired with Special List 44 YMS-46 row
- Finding type
- historical_record
- Finding
- Archival lead: NARA states that permanent deck logs of commissioned Navy ships are held in Record Group 24 and that 1941-and-later logs are generally held at College Park. The Special List 44 entry gives a date span for YMS-46, but no underlying log content, box-level finding aid, or materials file was reviewed in this pass.
