- Finding
- DANFS identifies SC-683 as built at American Cruiser Co., Trenton, Michigan; keel laid 9 April 1942; launched 14 October 1942; commissioned 30 November 1942; and transferred to Norway 21 October 1945.

[3]NavSource Online, SC-683 photo archive page [other_primary]

- SC-683 page: designation/history paragraph and specifications block
- Finding type
- vessel_history
- Finding
- NavSource identifies one hull as SC-683 ex-PC-683, states that it served the United States and Norway, and records the designation sequence: commissioned USS PC-683 on 30 November 1942, reclassified SC-683 in April 1943, transferred to Norway 12 October 1945 as KNM Hessa, transferred to the State Department/Foreign Liquidation Commission, and sold to Norway 7 June 1948. It classifies the hull as an SC-497 Class submarine chaser and gives 110 feet 10 inches length, 148-ton displacement, complement 28, and two 1,540-hp diesel engines on two shafts.

- Limitations
- NavSource says fate is unknown and does not provide a ship-specific asbestos record. Its 1945 transfer date differs from DANFS's 21 October 1945; both are retained as a documented date conflict. NavSource is used for the identity/designation correction and specifications, not as proof of asbestos aboard.

- Finding
- The National Archives ship-number list records SC-683 with the date span 11/30/1942 to 10/26/1943, corroborating the U.S. Navy commission/service window supplied for this hull.

[5]NHHC, Ship Histories: Abbreviations and Symbols [nhhc_danfs]
- Locator
- Entries for SC and PC in the abbreviations list
- Finding type
- historical_record
- Finding
- NHHC defines SC as a 110-foot submarine chaser and separately defines PC as a 173-foot submarine chaser; this supports retaining SC-683 as the canonical designation and correcting the class away from PC-461.

- SC index introduction and SC-497 class description
- Finding type
- historical_record
- Finding
- The NavSource class index describes the SC-497 class as wood-hulled, 110-foot submarine chasers built during World War II and notes that some were used by Allied navies under Lend-Lease; this is consistent with SC-683's documented Norwegian transfer.

- GAO product page highlights
- Finding type
- asbestos_application
- Finding
- GAO reports that its 1979 review concerned asbestos use in Navy ships, removal policy, and worker protection at Long Beach and Norfolk Naval Shipyards; it describes Navy policy to remove or replace asbestos insulation when damaged or removed for repairs, with later selective replacement in high-maintenance areas.

[8]Authenticated CourtListener v4 search sweep for this vessel [court_record]
- Locator
- Authenticated helper outputs in /tmp/b8057-hull-docket.json and helper pacing diagnostics; four required base-query ledger rows in this record
- Finding type
- litigation_documented
- Finding
- The one completed base query, exact hull-number opinion/docket sweep for "PC-683" docket records, returned six unrelated dockets (Sears Holdings, Panini America v. Fanatics, Xarelto, Roundup, Motors Liquidation, and Bed Bath & Beyond); none was qualifying asbestos litigation or a vessel match. The other three required base queries were not completed because the authenticated fleet pacing helper reported the shared request budget spent.

- Limitations
- This is a partial negative finding, not a full no-litigation conclusion. Three exact-name/hull base queries were blocked by fleet pacing; no asbestos-qualified variants were run because the completed base page did not overflow and variants are prohibited after incomplete/zero coverage. The unrelated hits are name collisions/other litigation, not evidence about this hull.
