- DANFS record for this hull: laid down as the unnamed submarine chaser PC-571 on 27 September 1941 at Portland, Oreg., by Albina Engine and Machine Works, Inc.; launched 12 February 1942, sponsored by Mrs. William Cornfoot (widow of the Albina founder); commissioned at Puget Sound Navy Yard 22 May 1942, Lt. Comdr. William R. McAdams, USNR. Northwest Sea Frontier from 15 June 1942; Alaskan sector (Kodiak, Adak, Dutch Harbor and other ports) on escort/patrol through spring 1944, screening U.S. Grant (AP-29), Oceanographer (AGS-3), Vega (AK-17) and merchantmen; Hawaiian Sea Frontier based at Pearl Harbor 24 April 1944 - May 1945; Service Force Pacific Fleet from 10 May 1945, reaching Eniwetok 10 June and operating out of Guam, Saipan, and Iwo Jima through war's end; postwar calls incl. Okinawa; reached Astoria, Oreg., 14 December 1945 for pre-inactivation overhaul; in reserve 23 March 1946; decommissioned 15 November 1946; assigned the name Anoka 15 February 1956 (never served actively under it); 'struck from the Naval Vessel Register on 1 November 1959'; sold 9 May 1960 to Tidewater Shaver Barge Line. DANFS specs block: dp. 280; l. 173'8"; b. 23'0"; dr. 6'6"; s. 22 k.; cpl. 65; a. 2x3", 2x20mm, 2 dct., 2 dcp.

- Limitations
- DANFS documents identity, milestones, and service narrative, not materials or asbestos content. Its strike date (1 November 1959) conflicts with NavSource, uboat.net, and NavalCoverMuseum (all 1 November 1957) - carried in gaps; its draft (6'6") and speed (22 k.) figures also diverge from NavSource specifications (10'10", 20.2 kts). The live page's class field renders 'PC-W1' - a page-rendering artifact; the class is PC-461 per all sources including the verbatim hazegray DANFS transcription.

Specifications: displacement 280 t (lt) / 450 t (fl); length 173'8"; beam 23'; draft 10'10"; speed 20.2 kts; complement 65; armament one 3"/50 dual-purpose mount, one single 40mm mount, three 20mm guns, two rocket launchers, four depth-charge projectors, two depth-charge tracks; propulsion two 1,440 bhp Fairbanks Morse 38D8 1/8 diesel engines (serial nos. 832231, 832232), Westinghouse single reduction gear, two shafts. Photo captions add ship-specific events: the ice-encrusted PC-571 bound for Kodiak on 13 January 1943 reporting to the Alaskan sector, and the 19-22 December 1942 rescue by PC-571 (Lt. Stanley W. Erdahl) of thirteen officers and crew of VP-42 PBY-5A BuNo 7285, which sank in Uyak Bay after towing; survivors taken to Kodiak NAS.

- Finding
- The builder's production table lists this hull: 'PC 571 | U.S. Navy | Sub Chaser | 284 | 174 | 22-May-42 | Named Anoku 1956, scrapped 1960' - corroborating builder, delivery date (22 May 1942, matching the DANFS/NavSource commissioning date), 1956 naming, and 1960 disposal. Yard history: Albina Engine & Machine Works, Inc., founded 1904 as a repair yard by William Cornfoot (the launch sponsor was his widow); flourished in WWII; sold to Dillingham Corp. circa 1971 becoming Dillingham Ship Repair; shipyard division became Cascade General in 1986, which concentrated at Swan Island and closed the original Albina yard on N. River Street, Portland. The same table lists sister chasers PC 569-570, 572, 578-582 and PC 1077-1082 plus twenty PCE hulls built at Albina.

Commanding officers (WWII): W R McAdam(s), USNR (22 May 1942 - mid/late 1942); M S Erdahl, USNR (to mid/late 1943); Ford Stoddard, USNR (to early 1945); E J Holstein, USNR (to mid 1945); W A Kruse, USNR (to late 1945). Documented events, sourced to submarine patrol reports: escorted USS Bowfin out of Pearl Harbor 16 July 1944; escorted USS Aspro out 21 November 1944; on 11 December 1944 (Lt. F. Stoddard) rendezvoused with and escorted in USS Sailfish and USS Pomfret ending their patrols at Pearl Harbor - corroborating the DANFS Hawaiian Sea Frontier narrative with patrol-report sourcing.

- asbestos_application
- Finding
- A steel-hulled PC-461-class diesel submarine chaser built September 1941-May 1942 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a diesel patrol craft of this type and period were engine and exhaust lagging, machinery-space thermal insulation, gaskets, valve packing, electrical insulation, and fireproofing/deck coverings. As a twin-screw diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

[9]Albina Engine & Machine v. Director, Office of Workers' Compensation Programs (McAllister), 627 F.3d 1293 (9th Cir. 2010), No. 09-70592 (decided December 10, 2010) [court_record]

- Opinion, 627 F.3d 1293, Background section (employment chronology, stipulations) and burden-of-proof analysis
- Finding type
- litigation_documented
- Finding
- Published Ninth Circuit opinion documenting asbestos exposure at this hull's builder yard: all parties stipulated that decedent James McAllister, a shipyard carpenter, died of mesothelioma caused by exposure to asbestos during maritime-situs employment for three Portland/Seattle shipyard employers, including Albina Engine & Machine, where he worked in 1956 doing work 'essentially identical' to his WISCO employment (WISCO admitted asbestos exposure at its yard). The litigation resolved which of the three employers was liable for LHWCA death benefits: the ALJ found the evidence insufficient to show an absence of exposure at Albina and assigned liability to Albina as last responsible employer; the Benefits Review Board affirmed; the Ninth Circuit granted review and, on burden-of-proof analysis, held Lockheed liable instead. Exposure at the Albina yard was treated as established in the record; the appellate disposition turned on burden allocation among employers, not on any finding that asbestos was absent at Albina.

It documents asbestos conditions at the builder's yard in the post-war era, not aboard this hull, and establishes nothing about materials installed in PC-571.

- Finding
- No qualifying ship-specific asbestos record located for this hull: no asbestos survey, abatement contract, hazmat disclosure, material specification, or verified litigation naming PC-571 or Anoka was found in the public sources searched. CAVEAT: CourtListener could not be queried this session - the fleet-wide request pacing budget was exhausted on four spaced attempts (helper's stand-down instruction honored) - so hull litigation status is logged as blocked, not as a negative result. Secondary web sweeps surfaced the yard-level Albina opinion (ev-08) and no qualifying hull case; the only other 'asbestos' content is law-firm marketing material (mesothelioma.net and mesotheliomalawyercenter.org occupational pages asserting asbestos at 'Albina Shipyard' without primary sourcing) - excluded by source policy.
