- vessel_history
- Finding
- NARA inventories deck-log runs for YMS-74 from 8 February 1943 through 30 September 1943 and from 1 January 1944 through 31 October 1945. These entries identify the numbered vessel and provide archival leads for its wartime operations and personnel records.

- 1943-02-08 to 1943-09-30; 1944-01-01 to 1945-10-31 (inventoried log coverage)
- Population
- U.S. Navy personnel recorded in the deck-log runs
- Limitations
- This is an inventory of deck logs, not a commissioning, decommissioning, construction, material, or asbestos record. The coverage dates are not asserted as continuous service dates and do not establish asbestos presence, products, quantity, individual exposure, causation, or legal eligibility.

[3]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct. 18, 1979), product-page summary [gao]
- Locator
- GAO product page, Highlights (direct access blocked, HTTP 403, 2026-10-05)
- Finding type
- gov_survey
- Finding
- GAO reviewed Navy use of asbestos in ships and the Navy's asbestos-removal policy at Long Beach and Norfolk Naval Shipyards. Its summary states that the 1975 policy was to remove and replace only insulation that was damaged or had to be removed for repairs, and that the policy changed in 1979 to selectively replace asbestos insulation in high-maintenance areas.

- Population
- Navy shipyard workers and Navy ships reviewed by GAO
- Limitations
- Navy-wide program and shipyard context, published after this hull's inventoried log coverage. The direct GAO product page returned HTTP 403 to this research environment; its indexed official product-page summary was used. It does not name YMS-74 or establish that this hull contained asbestos, identify products, quantify material, or establish exposure or legal eligibility.

[4]CourtListener API v4 authenticated searches via /Users/charlesfletcher/devin-prompts/cl-auth-search.py: exact-name opinion and docket queries for 'USS YMS-74'; hull-number opinion and docket queries for 'YMS-74'; limit 20 [other_primary]

- Helper diagnostics for each request: 'authenticated request' with no returned JSON result payload in this session
- Finding type
- historical_record
- Finding
- All four required authenticated CourtListener base queries were submitted. The helper emitted only authenticated-request diagnostics and did not return a result payload for classification in this session; no litigation conclusion is drawn.

- Limitations
- This is a pending, not negative, litigation result. No asbestos-qualified variants were run because no completed base query showed a 20-result overflow. Re-run the four base queries through the helper when fleet pacing permits; do not infer no litigation from this gap.

[5]Batch-9156 search ledger (this record): NARA Special List 44; authoritative-source identity searches; GAO product page; CourtListener authenticated helper [other_primary]
- Locator
- Search ledger entries sl-uss-yms-74-yms74-01 through -08
- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos survey, abatement record, hazardous-material disclosure, or other primary asbestos record for the canonical identity USS YMS-74 was located in the completed official-source searches. This is a bounded search result, not evidence that asbestos was absent.

- Limitations
- The CourtListener sweep is incomplete because result payloads were not returned after all four required base queries were submitted. NARA's inventory is a finding aid, not the deck logs themselves. Do not infer asbestos from the YMS designation, period, or assumed construction/materials.
