- Limitations
- This archived NHHC history establishes identity, dates, and service history only. It does not identify asbestos-containing material, quantify any material, establish exposure or causation for any person, or address legal eligibility. The live NHHC URL returned HTTP 404 on 2026-10-04; the citation is explicitly an archived capture.

- Finding
- NARA's Special List 44 identifies two online Navy-logbook date ranges for Impulse (PG-68): 16 March 1942 through 31 January 1944 and 1 March 1944 through 22 August 1945.

- USS Impulse ship's-log record series
- Limitations
- The list confirms online logbook coverage, not the contents of the logs. It does not establish asbestos presence, exposure, product identity, quantities, causation, or legal eligibility. The underlying logbooks remain a lead for future hull-specific review.

[4]CourtListener authenticated helper, attempted exact-name opinion query "USS Impulse" (blocked by fleet pacing before request) [court_record]
- Locator
- research-session helper diagnostic, 2026-10-04
- Finding type
- historical_record
- Finding
- The required CourtListener sweep was not completed: the authenticated helper declined the first exact-name opinion request because the fleet-wide paced request budget was momentarily spent, before any CourtListener API request was sent. No CourtListener result is represented as negative or positive.

- Study period
- 2026-10-04
- Limitations
- This is a search-access gap, not a litigation finding and not a negative search result. Per fleet instructions, no retry or anonymous CourtListener request was made after the pacing refusal; the remaining three base queries and any conditional variants remain unrun.

- Finding type
- asbestos_application
- Finding
- No ship-specific asbestos product, survey, abatement, environmental, or qualifying litigation record is carried in this record. Asbestos status aboard USS Impulse is unknown.

- Study period
- 2026-10-04
- Limitations
- This documents the bounded result of the completed accessible-source review, not proof that asbestos was absent. CourtListener was unavailable before a search ran, Firecrawl's keyless quota was exhausted, and the underlying NARA logbooks were not reviewed; the finding does not establish presence, absence, exposure, causation, or legal eligibility.
