[2]Ships Batch 8333 production scope, re-scoped 2026-09-29 per Trill fact-QA (crew signs 960-977) [other_primary]

- Batch instruction: USS YMS-460 scope correction
- Finding type
- historical_record
- Finding
- Batch scope correction: the hull was laid down as PCS-1415, redesignated YMS-460 on 27 September 1943 before commissioning, commissioned as YMS-460, and never served as PCS-1415.

- Limitations
- This batch-scope correction resolves the identity error only. It does not establish construction dates, builder, service events, asbestos aboard, individual exposure, or causation. PCS-1415 is retained solely as a pre-commissioning alias.

[3]National Archives, Special List #44, by Ship Numbers, entry YMS-460 [other_primary]
- Locator
- PDF table entry YMS-460
- Finding type
- historical_record
- Finding
- NARA's Special List #44, by Ship Numbers, lists YMS-460 with a deck-log coverage interval from 1944-05-27 through 1945-04-05. This establishes the existence and indexed date span of deck-log records for the hull, not commissioning, transfer, or individual service events.

- Limitations
- This finding aid shows the indexed coverage dates of deck logs. It does not itself establish a specific event on either endpoint, commissioning, transfer, service history, asbestos aboard the vessel, individual exposure, or causation.

[4]National Archives, Department of the Navy Records research guide [other_primary]
- Locator
- Opening research scope statement
- Finding type
- historical_record
- Finding
- NARA states that it preserves Department of the Navy permanent records and that only some Navy records have been digitized; many remain in paper or microfilm formats. This identifies a relevant archival research path and limits the meaning of an online search that did not retrieve further hull-specific records.

- Limitations
- General archival guidance only; it is not evidence about this ship, its asbestos condition, or a completed search of non-digitized holdings.

[5]Research result for this batch; see search ledger and access gaps [other_primary]
- Locator
- Searches documented in search_ledger
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, hazmat disclosure, or qualifying asbestos litigation record was located in the sources successfully reviewed for this batch. Ship-specific asbestos documentation is unknown.

- negative_finding
- Documentation level
- ship_specific
- Accessed
- 2026-10-04
- Limitations
- A bounded search result, not proof that records do not exist. Firecrawl search/scrape was unavailable due to exhausted hosted quota; only the exact-name CourtListener opinion search completed and returned zero results, while the remaining required base searches were paced out before requests could be sent. NARA notes that many Navy records are not digitized. No class-era inference is used to claim asbestos aboard this hull.
