[2]Naval History and Heritage Command, DANFS, SC-601 - SC-700, SC-651 entry (official search-indexed text; live URL returned 404 at research time) [nhhc_danfs]
- Locator
- SC-651 entry in the SC-601 - SC-700 hull-range record
- Finding type
- vessel_history
- Finding
- The NHHC hull-range entry identifies SC-651 as built at Westergard Boat Works, Biloxi, Mississippi; keel laid 4 November 1941; launched 14 May 1942; commissioned 8 August 1942; and transferred to France 16 November 1944.

- SC-651 crew, construction trades, and maintenance personnel
- Limitations
- Ship-specific construction and disposition history only. The live NHHC URL returned 404 during this research session, so the indexed official text was cross-checked against the live NARA ship-number list for the commissioning/service dates. The source does not state asbestos content, individual exposure, final French disposition, or a decommissioning date.

- PDF page 107; SC-651 rows
- Finding type
- historical_record
- Finding
- NARA's ship-number list records SC-651 with indexed logbook periods beginning 8 August 1942 and ending 31 March 1943, and beginning 1 November 1943 and ending 16 November 1944. These entries corroborate the commissioning date and the end date of the U.S.-indexed service record before transfer to France.

- U.S. Navy logbook records for SC-651
- Limitations
- The list is a logbook index, not a complete service history; its date ranges do not by themselves establish every operational assignment, a decommissioning date, or the exact date of transfer. It contains no asbestos or exposure information.

[4]NavSource Online, Submarine Chaser Photo Archive, SC-651 (live page checked as an archival lead) [other_primary]
- Locator
- SC-651 page, history and specifications sections
- Finding type
- vessel_history
- Finding
- The live NavSource hull page corroborates SC-651's Westergard Boat Works construction, 4 November 1941 keel laying, 14 May 1942 launch, 8 August 1942 commissioning as PC-651, April 1943 reclassification as SC-651, 16 November 1944 transfer to France as CH-135, and the listed class/specification profile: 148 tons, 110 feet 10 inches, 17-foot beam, 6-foot 6-inch draft, 15.6 knots, 28-person complement, and two General Motors 8-268A diesels on two shafts.

- SC-651 crew and construction/maintenance trades
- Limitations
- NavSource is an archival/photo reference rather than an official Navy record, so it is used as corroboration and lead material, not as the sole basis for the official identity decision. Its page does not establish asbestos content, exposure, final fate, or a decommissioning date; the April 1943 reclassification and CH-135 notation are not independently confirmed in the live official sources retrieved.

- GAO HRD-80-2 product-page summary
- Finding type
- gov_survey
- Finding
- GAO's Navy-wide review documents extensive Navy use of asbestos insulation and continuing shipboard applications including gaskets and pipe-hanger liners during the era relevant to a 1941-42-built submarine chaser.

- Navy ships and shipyard workers reviewed by GAO
- Limitations
- Program-level evidence only: GAO does not name SC-651, identify installed products aboard this hull, quantify material, establish present condition, or establish any person's exposure, disease, causation, or eligibility. The product page was live; the full report text was not used for a hull-specific assertion.

- Finding type
- historical_record
- Finding
- No qualifying ship-specific asbestos record was located: no SC-651 asbestos survey, abatement contract, hazardous-material disclosure, material inventory, or qualifying asbestos case naming USS SC-651 was found in the sources reviewed.

- Limitations
- A negative search result does not prove that asbestos was absent or that no claim exists. The public record reviewed does not characterize the hull's materials or any individual's exposure. The four required authenticated CourtListener base queries were run; no asbestos-qualified variants were run because no base query overflowed its 20-result page.

[7]NHHC SC-601 - SC-700 hull-range listing, identity cross-check [nhhc_danfs]
- Locator
- SC-651 heading and entry
- Finding type
- historical_record
- Finding
- Correction: the official NHHC hull-range listing places the vessel under SC-651, not PC-651. The record therefore follows the supplied rescope to USS SC-651, a wooden SC-497-class submarine chaser; PC-651 is retained only as the reported commissioning designation in the corroborating archival lead.

- Population
- U.S. Navy hull classification records
- Limitations
- The correction resolves the production record's vessel identity and does not claim that no temporary or commissioning-era PC designation was ever used. The live NHHC URL returned 404 at research time; the official indexed listing and the packet's per-hull identity were used for the correction.
