- SC-518 history and Specifications sections
- Finding type
- vessel_history
- Finding
- NavSource identifies the hull as an SC-497-class 110-foot wooden-hull submarine chaser, records PC-518 as its commissioning designation and SC-518 as its April 1943 designation, and lists striking from the Naval Register on 25 February 1946. Its class specifications list two General Motors 8-268A diesel engines, a two-shaft drive, and complement 28.

- Design complement 28
- Limitations
- NavSource is a naval-history archive, not an NHHC record. It resolves the batch identity: this is the wooden SC-497-class hull, not a PC-461-class patrol craft. The reported PC-518 designation is retained only as a pre-April-1943 designation for this same hull; this source contains no asbestos finding.

- Locator
- search_ledger sl-uss-sc-518-sc518-01 through -05
- Finding type
- historical_record
- Finding
- No public ship-specific asbestos survey, material specification, abatement record, hazmat disclosure, or qualifying asbestos litigation record for USS SC-518 was located in the accessible sources reviewed.

- Limitations
- A limited public-source review cannot establish that asbestos was absent or that no claim exists. CourtListener result pages were not returned because the authenticated fleet pacing acquisition did not complete within the Codex execution window; this is a litigation-search gap, not a zero-result finding.

- Finding type
- litigation_documented
- Finding
- CourtListener v4 sweep completed 2026-10-06 via authenticated helper: exact-name queries (USS SC-518 opinion and docket) returned zero results; hull-number queries (SC-518 opinion: 18 hits; SC-518 docket: 22 hits) returned only docket-number collisions (state-court SC-0518 numbering) and unrelated personal-name docket entries. No qualifying asbestos litigation and no other litigation involving USS SC-518 was found.

- Limitations
- Hull-number queries are high-collision (state docket numbering); all hits reviewed and classified as name collisions. No asbestos-variant queries run: exact-name bases are verified zero, and variants are subsets of the base.
