- SC-497 Class Characteristics; Class Grouping
- Finding type
- historical_record
- Finding
- NHHC describes the SC-497 class as 100 feet long, 17 feet beam, 148 tons full-load displacement, with accommodations for 3 officers and 25 enlisted; typical class propulsion was two diesel engines and two screws, with 1540- or 800-horsepower variants. The class grouping includes hulls 628-775, which places SC-650 in that class range.

[4]U.S. Government Accountability Office, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (1979) [gao]
- Locator
- GAO product page highlights; full report HRD-80-2
- Finding type
- gov_survey
- Finding
- GAO reviewed Navy ship asbestos use and reported that the Navy used asbestos in ship insulation; its summary describes thermal insulation and continuing shipboard applications including gaskets and pipe-hanger liners. This supplies Navy-era context for a 1941-42-built vessel.

- Population
- Navy shipyard workers and Navy ships reviewed by GAO
- Limitations
- Program-level and fleet-level evidence, not an SC-650 record. The report does not name SC-650, establish installed materials aboard this hull, quantify material, or establish any person's exposure or disease. The linked GAO page was live at research time; the full report was not used to make a hull-specific claim.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located: no asbestos survey, abatement contract, hazardous-material disclosure, or qualifying asbestos case naming USS SC-650 was found in the sources reviewed. The four required authenticated CourtListener base queries produced no returned hits: exact-name opinion, exact-name docket, hull-number opinion, and hull-number docket.

- Limitations
- A negative search result is not proof that asbestos was absent or that no claim exists. CourtListener asbestos-qualified variants were not run because no base query overflowed its 20-result page. Firecrawl MCP research was unavailable because the keyless service reported a multi-hour quota reset; official-source fallback research was used and the access gap is reported.

[6]NHHC DANFS hull-range record, checked against the supplied 2026-09-29 rescope [nhhc_danfs]
- Locator
- SC-650 entry and page title
- Finding type
- historical_record
- Finding
- Correction: the authoritative NHHC hull-range record treats 650 as SC-650 and places it in the SC-601 - SC-700 listing; the record does not identify this hull as PC-650. The record therefore supports the rescope to USS SC-650, not a PC-vessel identity.

- Limitations
- This corrects the vessel identity for this record. It is based on the NHHC listing and does not by itself prove that no administrative or planning reference ever used a different designation.
