- Construction trades (Fulton Shipyard, Antioch, 1942); crew (complement ~21-25); embarked troops (capacity ~66)
- Limitations
- ShipScribe is a respected unofficial transcription of official register data, not itself an official record. Launch date conflicts with NavSource (8 Sep 1942) - unresolved; decommission date is single-source. The two MC dates (21 May 47 transfer vs 14 May 47 sale delivery) are printed in that order in the source and are reproduced as-is. No asbestos or materials information in the source.

[2]Navy and Marine Corps Awards Manual (NAVPERS 15,790, 1953 revision), Part IV - List of Ships and Units Eligible for Engagement Stars (official publication; HyperWar transcription) [other_primary]

- Finding type
- vessel_history
- Finding
- The official engagement-star eligibility list records 'APc 31: 1 Nov 43, P24-2' - the ship's participation in the Treasury Island landing (27 Oct - 6 Nov 1943), a component of the Treasury-Bougainville operation (P24), for which one engagement star was authorized. Independently corroborated by naval historian David Bruhn's 'APc and FS Hall of Valor' compilation listing 'USS APc-31 1 Nov 43 Lt. R. H. Loomis, USNR' under the Treasury Island landing.

- Finding
- NavSource chronology: originally planned as coastal minesweeper AMc-185; laid down 1942-07-15 at Fulton Shipyard, Antioch, CA; launched 1942-09-08; commissioned USS APc-31 1943-01-30 with LT Roland H. Loomis USNR in command. WWII assignment: Asiatic-Pacific Theater - APc Flotilla Five (LT G. D. Winsor USNR), APc Group Thirteen (LT D. V. Horsburgh USNR), APc Division Twenty-Six; campaign: Treasury-Bougainville operation, Treasury Island landing, 1 Nov 1943. One battle star for WWII service; struck from the Naval Register 1946-03-12; 'final disposition, fate unknown.' Six commanding officers listed (Loomis, Skinner, Armour, Valeri, Herreman, Johnson); page states no DANFS history exists for this hull and no images are archived.

- Crew (3 officers + 22 enlisted per page; ~66 embarked troops at capacity)
- Limitations
- Secondary volunteer compilation - the sole public source for the flotilla/group/division assignment and the commanding-officer sequence, which shows an unexplained gap (Loomis to Mar 1943, then Skinner from Mar 1944). Launch date (8 Sep) conflicts with ShipScribe register data (18 Sep) - unresolved. Awards consistent with the official Awards Manual entry (ev-02). No asbestos information; 'fate unknown' is contradicted in detail only by the MC sale record in ev-01.

[4]ShipScribe, USS APc-1 class - class header specifications and procurement narrative (transcribed from official BuShips/OPNAV records) [other_primary]
- Locator
- APC-1 class page - header spec block and 'Class Notes' procurement narrative
- Finding type
- vessel_history
- Finding
- Class context and designation consolidation: on 1942-01-19 CNO directed construction of 50 coastal minesweepers AMc-150-199 to the modified Accentor-type design (wooden hull, ~103 ft, diesel ~400 hp). On 1942-04-13 CNO requested the fifty be built as 'raider transports, AP'; the District Craft Development Board recommended the change 1942-04-20 and the category 'Coastal transport (small), APc' was created 1942-04-22; AMc-150-199 became APc-1-50 (not respectively). Class spec: 161 t light / 258 t limiting, 103.25 ft oa, diesel 400 hp single screw, 10 kts, complement 21 (1944), four single 20mm, troop/cargo roles with a 2-ton boom serving a forward hatch. Wooden hull and diesel propulsion mean the class carried no boilers or steam plant - the machinery category most associated with documented WWII-era asbestos insulation.

- Shipyard workers and class crews (class context)
- Limitations
- Class-level specification and procurement history - documents the type's plant and the designation reclassification, not materials aboard this hull. Absence of a steam plant removes the most commonly documented WWII asbestos pathway but does not establish that no asbestos-containing material was aboard (gaskets, exhaust insulation, electrical insulation, fireproofing compounds remain undocumented either way).

- Finding type
- asbestos_application
- Finding
- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program context in which this 1942 wooden-hulled coastal transport was built - and that wartime demand drove unprecedented asbestos utilization across naval construction.

[6]CourtListener API v4 opinion search for 'APc-31'/'APC-31' - sole result: In re Koi Design LLC v. Marron Lawyers, APC, No. 23-55704 (9th Cir. 2026) [court_record]

- Finding
- The only CourtListener opinion hit for the hull-number queries is a name collision: 'Marron Lawyers, APC' is a law firm (APC = a professional corporation) in a 2026 Ninth Circuit legal-malpractice dispute - not the vessel, not asbestos litigation, no relation to any ship.

- No qualifying ship-specific asbestos record located under either designation: no asbestos survey, abatement contract, hazmat disclosure, or docketed asbestos case naming AMc-185, APc-31, or APC-31 was found in the public sources searched (see search_ledger). No DANFS entry exists for this unnamed numbered craft. The only litigation hit is the name collision in ev-06.
