- Finding
- NHHC's SC-401–SC-500 page identifies the SC-497 class as wooden-hull submarine chasers with 100-foot overall length, 17-foot beam, 148-ton full-load displacement, diesel propulsion on two screws, and accommodations for 3 officers and 25 enlisted; its class grouping includes the SC-628–SC-775 series, which contains SC-747.

- Population
- SC-497-class construction and operating personnel
- Limitations
- Class-level information only; it does not establish SC-747's individual construction dates, machinery fit, complement, asbestos materials, exposure, or final disposition. Direct page access returned 502, so the indexed NHHC result is retained as a documented access gap rather than treated as a fully scraped page.

- I-26 chronology, 24 April 1943 entry
- Finding type
- vessel_history

- Study period

- Population
- SS Kowarra survivors; SC-747 crew
- Limitations
- Documents a historical rescue event involving this hull, not asbestos materials, exposure, medical causation, or legal eligibility. CombinedFleet is a specialist secondary naval-history source, not a U.S. government record; the event is retained because it independently identifies SC-747 and matches the supplied research lead.

- Finding

- Population
- SS Kowarra survivors; SC-747 crew and convoy personnel
- Limitations
- This corroborates the rescue event but does not document asbestos, individual exposure, causation, or the complete service history of SC-747. The source is a historical compilation rather than a Navy archival record.

[4]Authenticated CourtListener helper attempt; fleet-wide pacing budget reported momentarily spent before the four-query sweep could be completed [other_primary]
- Locator
- Batch report CourtListener gap; helper stderr on 2026-10-03
- Finding type
- historical_record
- Finding
- No CourtListener litigation conclusion is drawn for SC-747 in this batch: the helper accepted the exact-name opinion request but the shared fleet limiter then reported its request budget was momentarily spent, so the base sweep was not completed.

- 2026-10-03
- Limitations
- This is an access/completeness limitation, not a finding that no litigation exists. The exact-name docket and both hull-number queries were not completed; asbestos variants were correctly not run because no base query overflow was established. No anonymous or raw CourtListener request was made.

- Locator
- Batch source review and gaps section
- Finding type
- historical_record
- Finding
- No ship-specific asbestos survey, abatement contract, hazmat disclosure, asbestos product list, or other direct material record for USS SC-747 was located in the sources reviewed.

- 1942-1945 and later disposition
- Population
- SC-747 crew, shipyard workers, and later custodians
- Limitations
- This negative finding is bounded by the sources reviewed and the incomplete CourtListener sweep. It does not prove that asbestos was absent from the vessel, nor does it establish or defeat any exposure or legal claim.
