- Finding type
- vessel_history
- Finding
- Official BuShips characteristics and construction record for this hull: the individual construction table under 'Consolidated S. B. Co., Morris Heights, N. Y.' lists PC1204 with keel laid 27 February 1943, launched 14 April 1943, and first commissioned 6 August 1943; the individual machinery table lists PC1204 with H.O.R. (Hooven-Owen-Rentschler) R-99DA engines, 2,880 brake horsepower, reduction-gear entry 'None', 348 tons trial displacement and 20.2 knots trial speed. The '173' PC' class block documents the type: 173'8" overall / 170'0" waterline length, 23'0" extreme beam, 280 tons standard / 450 tons full-load displacement, two diesel-driven propellers with single-reduction gearing, two 60 kW 120 V DC diesel-driven ship's-service generators, 470 barrels diesel oil, accommodations for 4 officers and 61 enlisted, ultimate approved armament one 3"/50 dual-purpose gun and one single 40 mm AA mount.

- Limitations
- This is an official construction and characteristics record, not a materials or asbestos record. It does not document insulation composition, asbestos-containing products, crew exposure, or legal eligibility. The individual machinery row's 'None' under reduction gear conflicts with the class block's single-reduction-gearing entry and with NavSource's Westinghouse attribution; variance carried in gaps.

- Muster rolls are personnel rosters: they document who served aboard and when - directly relevant to exposure-population research - but were not reviewed page-by-page in this batch and do not themselves record asbestos, materials, or exposure events. The deck-log series indexed in SL-44 ends 6/30/1945; later deck-log coverage may exist in other NARA series. The muster-roll end date (10 October 1946) is a coverage marker, not a documented decommissioning date.

U.S. Navy decommissioning and striking dates are not stated by either source and remain unverified. No image or DANFS history exists for this hull per NavSource.

- asbestos_application
- Finding
- Class/era asbestos-relevance assessment for this hull type: the PC-461 class was a 173-foot steel-hulled, diesel-powered patrol craft with no boilers and no steam plant (official BuShips Ships' Data 1945 class block: diesel engines, two diesel-driven generators, diesel-oil fuel), so the dominant WWII naval-asbestos pathways (boiler insulation, turbine lagging, steam-line lagging) do not apply. Asbestos-relevant applications for a 1943 steel diesel patrol craft of this era are the era-typical items: diesel engine and exhaust-system lagging, machinery gaskets and valve packing, electrical insulation and switchboard backing, deck coverings and mastics, adhesives, and friction linings (brake linings) on deck machinery.

- Limitations
- Class/era inference only - no ship-specific document identifies any asbestos-containing product installed aboard this hull, and no product, location, or quantity is asserted as present. The diesel (non-steam) plant materially narrows the expected application set relative to steam warships. Does not establish presence or absence of asbestos aboard, individual exposure, or legal eligibility.

- Finding
- No qualifying ship-specific asbestos record located for PC-1204: no asbestos survey, abatement contract, material inventory, hazmat disclosure, museum record, or qualifying litigation record naming this hull was found in the authoritative public sources searched (see search_ledger). The vessel was sold out of government custody in 1948 with fate unknown - there is no surviving hull, museum custody, or reserve-fleet record from which a modern survey could be expected. The CourtListener component is incomplete: the required authenticated helper returned a daily-quota stand-down (~2.4-hour wait) before results could be searched on 2026-10-03, so no conclusion about qualifying litigation is represented.
