[3]U.S. Defense Nuclear Agency, Operation Crossroads, 1946 (DNA 6032F) [other_primary]

- DNA 6032F, YMS-354 vessel entry
- Finding type
- vessel_history
- Finding
- The Defense Nuclear Agency's Operation Crossroads history identifies YMS-354 as a Survey Unit minesweeper tasked with surveys of probable test effects on fish and wildlife and ocean currents near Bikini Atoll; it reports a crew size of 28, Bikini arrival 27 March 1946, departure 14 September 1946, decontamination at Guam/Marianas, operational clearance 20 December 1946, and final clearance 10 February 1947.

- Limitations
- The official DTRA PDF returned HTTP 403 to direct retrieval; its indexed official text was retrieved through the live-search fallback and independently matches the stated vessel entry. It documents Operation Crossroads assignment and stated radiological-clearance milestones, not asbestos content, condition, individual dose, health outcome, or legal entitlement. The clearance dates must not be read as an asbestos finding.

- Finding type
- gov_survey
- Finding
- GAO's 1979 review reports that the Navy used asbestos in ships generally, including thermal insulation as its major shipboard use, and describes the Navy's 1975 and 1979 replacement policies.

- Population
- Navy ships and shipyard workers reviewed by GAO
- Limitations
- Navy-wide, post-service program evidence only. It does not name YMS-354 or establish that any asbestos-containing material was installed, retained, disturbed, or exposed anyone aboard this hull. Direct PDF retrieval returned HTTP 403; the live GAO product page and its linked report metadata were verified.

[5]CourtListener API v4 authenticated searches via fleet helper cl-auth-search.py: "USS YMS-354" (opinions and dockets) and "YMS-354" (opinions and dockets), limit 20 [court_record]
- Locator
- Local helper outputs cl-yms354-name-opinion.json, cl-yms354-name-docket.json, cl-yms354-hull-opinion.json, and cl-yms354-hull-docket.json; each count 0
- Finding type
- litigation_documented
- Finding
- No qualifying asbestos litigation record naming USS YMS-354 or YMS-354 was located in the four required authenticated CourtListener base searches: exact-name opinion, exact-name docket, hull-number opinion, and hull-number docket. Each returned zero results at a 20-result limit.

- Limitations
- A zero-result CourtListener sweep means no qualifying indexed record was located; it does not prove that asbestos was absent aboard the hull, that no litigation exists elsewhere, or that any person was or was not exposed. No asbestos-qualified variants were run because no base search overflowed 20 results.

[6]Batch 8986 research ledger: NARA Special List 44 and deck-log guidance; NHHC Pacific Fleet and Operation Crossroads pages; Defense Nuclear Agency Operation Crossroads history; GAO HRD-80-2; authenticated CourtListener base searches [other_primary]
- Locator
- search_ledger entries sl-uss-yms-354-yms354-01 through -08
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, material schedule, product identification, or qualifying indexed litigation record was located in the authoritative sources searched. NARA's deck-log inventory identifies an unretrieved hull-specific archival path, but the inventory is not a materials record.

- Limitations
- Absence of a located public record is not proof of absence of asbestos. Unretrieved deck logs and unlocated Bureau of Ships construction or alteration records remain the principal archival gaps; this finding establishes neither exposure nor non-exposure.
