- Finding
- Ordered 19 Feb 1942 under the 19 Jan 1942 CNO directive for 50 coastal minesweepers AMc 150-199; re-roled with the rest of the batch to small coastal transports (APc) after the 13 Apr 1942 CNO 'raider transports' request and the 22 Apr 1942 creation of the APc category. This hull, designated AMc-156, was laid down 6 Apr 1942 at Camden Shipbuilding & Marine Railway, Camden, ME; launched 25 Jul 1942; and commissioned as USS APc-16 on 15 Jan 1943.

- Construction trades, Camden ME yard (1942)
- Limitations
- Register-derived data via transcription; the vessel was never commissioned as a minesweeper - AMc-156 is the pre-completion designation only. Launch date conflicts with NavSource's 5 Jul 1942 (register-derived 25 Jul 1942 carried; conflict in gaps). Establishes identity and build history only - contains no materials or asbestos information.

- Finding
- Official BuShips data book lists APc-16 (ex-AMc-156) with a National Supply MML-6 diesel engine, 400 shaft horsepower, no reduction gear, single screw, in the APc-1 class block: wood hull, 103'3" overall, 98'2" waterline, 21'3" extreme beam, limiting displacement 258 tons, limiting draft 9'3", designed speed ~10 knots (no trial runs or model-basin tests made), accommodations 3 officers + 22 enlisted ship's company, troop capacity 66 enlisted, 2-ton boom, armament 20mm guns and smaller.

- Official wartime specification record for this hull. A specification table is not a materials inventory: it establishes propulsion and hull type (diesel, wood - no boilers or steam systems) but says nothing about insulation, lagging, or asbestos content aboard.

- Finding
- The official awards manual credits APc 16 with two WWII engagements: 22 Sep 1943 under code P17-3 (Finschhafen occupation, Eastern New Guinea operation) and 4-18 Jan 1945 under code P32-2 (Lingayen Gulf landing, Luzon operation) - two battle stars.

- Ship's company (~25) plus embarked troops during landing operations
- Limitations
- Establishes campaign participation credits only; says nothing about damage, casualties, cargo, or exposure conditions. NavSource labels the 22 Sep 43 credit 'Lae occupation,' but the manual's own code list assigns 22 Sep 43 to P17-3 (Finschhafen occupation; the Finschhafen landing day) while Lae occupation is P17-2 (4-22 Sep 43) - the NavSource label appears erroneous and is not used.

- Finding
- NARA's deck-log inventory lists logbooks for APC-16 covering 15 Jan 1943 (commissioning) through 30 Jun 1945 - the ship's own wartime operational record exists in NARA's Navy deck-log holdings and is the best lead for in-port availability, repair, and any material-condition remarks.

- Limitations
- A finding aid entry only: it establishes that the logs exist and their date coverage, not their contents - logs were not examined for this record. No APC-16 logs are listed after 30 Jun 1945; coverage of Jul 1945-May 1946 (including the Subic Bay decommissioning period) is unverified.

- Finding type

- Finding
- Register record: decommissioned 9 May 1946 at Subic Bay, Philippines; stricken from the Naval Register 21 May 1946; driven onto the beach with her bow smashed in a typhoon at Subic Bay in Sep 1946; wreck sold by the Foreign Liquidation Commission 16 Jan 1948 and abandoned by the buyer.

- Population
- Decommissioning/detail personnel at Subic Bay (1946); FLC disposal workers (1946-48)
- Limitations
- Register-derived disposal record. NavSource's 'transferred to a foreign government' diverges from the register-derived FLC wreck sale and is not used. Final disposition of the abandoned wreck is undocumented - no museum, memorial, or government custodian exists for this hull, so the preservation-era disclosure channel that produced asbestos records for museum ships never applied.

[6]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979) [gao]
- Locator
- GAO product page HRD-80-2 (full text blocked, HTTP 403)
- Finding type
- asbestos_application
- Finding
- GAO documents that asbestos-containing insulation and related materials were standard aboard Navy ships of this era and that the Navy did not begin substituting insulation materials until the 1970s - the fleet-wide context for WWII-era construction. For this 103-ft wood-hulled diesel transport, plausible asbestos scope was limited to items such as engine-exhaust lagging, machinery gaskets and packing, and electrical/joiner insulation; the dominant asbestos loads of the era (boiler and steam-line insulation) were absent by design.

- Limitations
- Program-level documentation, not hull-specific; the report postdates the vessel by three decades and addresses large shipyard/ship systems, not small district craft. The reduced-scope estimate is an inference from the documented diesel/wood configuration - no hull-specific material record exists.

- Finding
- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, materials inventory, museum hazmat disclosure, or docketed litigation naming APc-16 or AMc-156 was found in the public sources searched (see search_ledger). The hull was destroyed in place as a wreck (1946-48), so no preservation-era survey channel ever existed.

- Limitations
- Absence of a located public record does not prove absence of asbestos aboard - era-typical materials were standard. The CourtListener API sweep was throttled at research date (HTTP 429); the ship-name check ran via public web index only and could miss cases outside the index. Deck logs (ev-04) were not examined and could contain repair/material remarks.
