Sister 'SC 667 | US Navy | Sub Chaser | 136 GT | 22-Sep-42 | Later PCC 667, to the NDRF 1948.' Yard context: Joseph Weaver and Son started 1897 building barges for the Galveston Navigation District; renamed Weaver Shipyards 1941; WWII contracts awarded 1941-42 for wooden mine sweepers and sub chasers - the table lists 26 YMS minesweepers delivered plus the two sub chasers; post-war small vessels and repair; sold 1975, family regained late 1980s.

- Texas Historical Commission marker text for the builder: 'World War II again increased production at the Weaver yard, when contracts to construct wooden mine sweepers and sub chasers were awarded in 1941 and 1942. The wooden vessels did not attract the magnetic mines used by the Germans, and were designed to patrol the waters adjacent to their home bases.' Documents that the yard's wartime naval production - which included this hull - was wooden construction of minesweepers and sub chasers.

Documents transfer into French service in September 1944 (matching NavSource's 27 September 1944), renumbering to CH-712 in 1950 and P-712 (patrouilleur) in 1950, and discard in 1953. A French naval postal-history page gives 'desarme 08 decembre 1953' (decommissioned 8 December 1953) and the same CH-712/P-712 sequence.

NavSource gives the US-side fate as 'unknown' - the 1953 discard and the CH-712/P-712 renumbering rest on secondary sourcing, hence partial verification. The forum's 8 December 1953 decommissioning date is plausible and consistent with navypedia's 1953 discard but is the weakest source used. No asbestos content.

- Class-level context for the SC-497 type this hull belongs to: 475 ordered, 37 cancelled, 438 delivered at ~$500,000 each; 142 lend-lease transfers (France 50, Russia 78, Brazil 8, Norway 3, Mexico 3). Class specifications: length 110'10", beam 17'11.5", displacement 98 tons, complement 3 officers + 25 enlisted; wooden hull throughout - the 'splinter fleet' built for offshore patrol and ASW; SCs also served as beach control craft (SCC) in amphibious landings in North Africa, Sicily, Italy, and France, and air-sea rescue in the Channel. The page's 'SC WAR RECORD' casualty table independently corroborates this hull's 13 September 1943 collision: 'SC 666 | Damaged in collision off Italy | 09-13-43' (same date as NavSource; 'off Italy' vs NavSource's 'Gulf of Salerno').

- Finding type
- asbestos_application
- Finding
- A wooden-hulled diesel submarine chaser built 1941-42 sits inside the Navy's documented asbestos-use era. Era-standard applications aboard a vessel of this type and period were diesel-exhaust lagging, engine gaskets and packing, electrical insulation, fire-resistant paneling in machinery spaces, and winch/windlass brake linings. As a wooden-hulled diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, and her asbestos-relevant material footprint is materially smaller than a steel steamship's.

Names era-standard applications, not confirmed installed materials. No quantity. Product names are normalized era terms; no manufacturer attribution for this hull. Wooden construction reduces but does not eliminate the inference - gaskets, exhaust lagging, and electrical materials were asbestos-bearing across vessel types in 1942.

CourtListener coverage: 'SC-666' opinion returned 2,591 hits, 'SC-666 asbestos' variant 68 hits, 'PC-666' opinion 2,728 hits, and 'PC-666' docket 24,353 hits - every classified hit is a docket-number or reporter-pincite collision (Kentucky '2016-SC-0666', Tennessee 'SC-DDT-DD' and 'R3-PC' dockets, '666 N.E.2d 8', '420 B.R. 666', 'Perez v. 666 LLC'), none the vessel; the 'SC-666' RECAP docket query was fleet-pacing blocked all session (~90 min of bounded retries) and is logged open, not negative. Secondary web sweeps surfaced only law-firm marketing listicles asserting asbestos aboard without primary sourcing - excluded by source policy.

- Absence of a located public record does not prove absence of asbestos aboard - era inference supports era-consistent materials. Litigation coverage is PARTIAL this session: four of five planned CourtListener queries completed (all collisions); the 'SC-666' RECAP docket query remains an open lead, not a negative result. Small wooden auxiliaries of this type are rarely named in the asbestos-litigation record, which is dominated by larger steam vessels and yard employment - a coverage skew, not exoneration. Does not establish or defeat any claim of exposure or legal eligibility.

- Finding
- DESIGNATION CLARIFICATION: this hull is documented two ways. NavSource says she was commissioned USS PC-666 on 2 September 1942 and reclassified SC-666 in April 1943 - the same sequence NavSource shows for sister SC-667 (same yard, commissioned PC-667 22 Sep 1942 -> SC-667 April 1943) and SC-665 (PC-665 10 Aug 1942 -> SC-665 April 1943). Navypedia's US table carries her as bare 'SC666' without a PC designation, and uboat.net is silent on it. Either way the physical hull was always an SC-497-class wooden submarine chaser - she was never a PC-461-class steel patrol craft; 'PC-666' was at most a paper designation worn ~7 months during a Navy-wide reclassification of the 110-foot block.
