- Limitations
- The live NHHC URL returned 404 on 2026-10-03; the cited Wayback capture is explicitly archived. This concise hull-register entry establishes the stated construction, commissioning, and transfer facts. It does not state hull material, preliminary designation, machinery, complement, detailed service history, Soviet service name, asbestos content, occupational exposure, or present condition.

- Finding type
- historical_record
- Finding
- NHHC's SC-497-class grouping includes hull numbers 628–775, which encompasses SC-774. The class-characteristics block gives generic dimensions, accommodations of 3 officers and 25 enlisted personnel, diesel machinery with two screws, and two alternative power/speed installations.

- Limitations
- The live NHHC URL returned 404 on 2026-10-03; the cited Wayback capture is explicitly archived. This is class-level context, not a hull-specific machinery, complement, hull-material, armament, or asbestos finding. NHHC expressly says the class had alternative power plants and that armament varied; none of those generic characteristics is treated as installed aboard SC-774.

- USS SC-774 crew covered by extant logbook span
- Limitations
- The list establishes an archival logbook date span, not the contents of the logs. It does not establish decommissioning, transfer mechanics, service locations, asbestos content, occupational exposure, or causation. The terminal date precedes NHHC's 17 August 1945 transfer date by one day and is not treated as a contradictory disposition date.

- Limitations
- The live NHHC URL returned 404 on 2026-10-03; the cited Wayback capture is explicitly archived. The roster supports only that the document associates SC-774 with Lt. (jg) C. F. Mathews on its 1 May 1945 listing. It does not provide service narrative, a complete command chronology, crew complement, asbestos content, exposure, or causation.

- Locator

- Finding type
- asbestos_application
- Finding
- No public ship-specific asbestos survey, abatement record, product identification, hazmat disclosure, or authoritative asbestos finding naming USS SC-774 was located in the documented NHHC, NARA, NVR, and museum-archive source review. CourtListener search attempts were made through the required authenticated helper but did not return results before the execution environment terminated them; they are an access gap, not a CourtListener no-result or litigation negative finding.

- Study period
- Research through 2026-10-03
- Limitations
- This is a bounded negative finding from the documented authoritative-source review, not proof that asbestos was absent. The CourtListener sweep is incomplete and cannot support a statement that no litigation exists. Secondary, law-firm, marketing, forum, and Wikipedia material was excluded under source policy.
