[2]Ships of the U.S. Navy, 1940-1945, USS YMS-53 entry (HyperWar transcription of the wartime Navy reference) [other_primary]

- USS YMS-53 entry: dimensions, machinery, builder, commissioning, striking, and sale lines
- Finding type
- vessel_history
- Finding
- The Ships of the U.S. Navy, 1940-1945 reference entry identifies USS YMS-53 as a 136-foot motor minesweeper of 320 tons full load, built by Wheeler Shipbuilding Corporation in Brooklyn, New York, and commissioned 1 September 1942. It records diesel reduction engines, twin screws, a 4-officer/29-crew complement, striking from the Naval Register on 3 July 1946, and sale to Simon Bacon at San Pedro on 9 December 1947.

- Limitations
- The page is a transcription/mirror of a wartime Navy reference rather than a current Navy registry. It does not state keel-laying, launch, decommissioning, post-1947 disposition, or asbestos content; the 4-officer/29-crew figure is a class/reference figure and is not asserted as a YMS-53 muster roll.

- Finding type

- Finding
- NARA Special List 44 indexes U.S. Navy deck logs for YMS-53 from 1 September 1942 through 31 October 1945.

- Limitations
- This is a NARA holdings index, not the deck-log content. The coverage dates describe indexed records and are not asserted as commissioning or decommissioning dates. The logs were not reviewed and the index does not establish asbestos, materials, exposure, or causation.

[4]Naval History and Heritage Command, Seventh Amphibious Force Command History 1945 [nhhc_danfs]
- Locator
- Online reading-room page, Lingayen Gulf minesweeping paragraph: YMS 53 damaged
- Finding type
- historical_record
- Finding
- The NHHC-hosted Seventh Amphibious Force command history states that YMS 53 was damaged during the Lingayen Gulf minesweeping and assault operations in January 1945. This is a ship-specific wartime operational reference, not an asbestos or injury finding.

- Limitations
- The command history supports the reported operational event only. It does not identify the damage mechanism beyond the surrounding account, damage extent, repairs, asbestos, or crew exposure.

[5]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 [gao]
- Locator
- GAO product record highlights and linked full report, Navy ship asbestos-use discussion
- Finding type
- gov_survey
- Finding
- GAO's Navy-wide 1979 review states that Navy officials reported asbestos in some ship components, including clutches and electric cables, and identified thermal insulation as the Navy's major use. This is historical Navy-wide context only; it does not identify YMS-53 or any product aboard it.

- Limitations
- Program-level evidence about Navy ships generally. It cannot establish installation, product identity, quantity, condition, removal, exposure, or causation aboard YMS-53; no product is normalized for this hull.

[6]Batch-9133 bounded research result; see source and CourtListener search-ledger rows [other_primary]
- Locator
- search_ledger rows sl-uss-yms-53-yms53-01 through sl-uss-yms-53-yms53-10
- Finding type
- asbestos_application
- Finding
- No qualifying ship-specific asbestos record was located in the authoritative sources reviewed: no survey, abatement record, hazmat disclosure, product-identification record, or qualifying ship-specific litigation record naming YMS-53 was found. Ship-specific asbestos documentation remains unknown.

- Limitations
- A bounded search result is not proof that no such record exists. The NARA deck logs were indexed but not read, many archival records may be undigitized, and the CourtListener queries did not return HTTP results because the fleet pacing gate was unavailable. This finding neither establishes nor defeats exposure, causation, or legal eligibility.

[7]Authenticated CourtListener API v4 helper invocation log, 2026-10-05 [other_primary]
- Locator
- search_ledger rows sl-uss-yms-53-yms53-07 through sl-uss-yms-53-yms53-10; helper stderr recorded pacing wait/no HTTP response
- Finding type
- historical_record
- Finding
- The required authenticated CourtListener base sweep was incomplete. The exact-name opinion query ("USS YMS-53") was invoked twice after the first invocation produced no result, and the exact-name docket ("USS YMS-53"), hull-number opinion ("YMS-53"), and hull-number docket ("YMS-53") were each invoked once; the helper did not return an HTTP response because the fleet-wide pacing gate was unavailable. No asbestos-qualified variants were run because no base query produced a 20-result overflow.

- Limitations
- This is an access-gap record, not a zero-result litigation finding. Because the helper never returned result payloads, every possible opinion/docket hit remains unclassified. The duplicate exact-name opinion invocation was an execution error and was not used to claim an additional search result.
