- Finding
- DANFS record for this hull: laid down 27 September 1941 at Portland, Oreg., by Albina Engine & Machinery Works, Inc.; launched 28 February 1942; sponsored by Mrs. Ernest Haycox; commissioned 19 June 1942 (Lt. Comdr. Arthur H. Middleton, USNR). Northwest Sea Frontier July 1942; Kodiak/Seward escort and ASW September 1942-February 1943; Aleutians (Dutch Harbor, Adak, Attu; Akutan Pass convoy escort) from February 1943; Puget Sound navy-yard overhaul 23 November 1943-25 February 1944; Western Sea Frontier April 1944; CinCPac September 1944; Eniwetok-based convoy screening under TF 96 (Saipan, Peleliu, Ulithi) October 1944-March 1945; Tarawa air-sea rescue duty May-October 1945; Charleston navy-yard overhaul early 1946; Caribbean operations 1946-49; Norfolk home port 1949; east-coast operations to 1959; named Tooele 15 February 1956; decommissioned 9 February 1959 at Green Cove Springs, Fla.; struck from the Navy list 1 July 1960. One battle star for World War II.

- DANFS documents service history and specifications, not materials or asbestos content. DANFS's Alaska chronology (Kodiak September 1942-February 1943) conflicts with the uboat.net/NavSource account crediting this hull with the SS Trevalgan rescue off Trinidad 1-3 December 1942 - carried as disputed (see ev-03, gaps). DANFS lists the class as 'PC-451' where NavSource/uboat.net give PC-461 - carried in gaps. DANFS spec block (270 t; 169'7") differs from NavSource's (280/450 t; 173'8") - carried in gaps.

- Finding
- NavSource timeline and specifications for this hull: launched 23 February 1942 (conflicts with DANFS 28 February - see gaps); commissioned 19 June 1942; credits PC-572 with rescuing the 43 survivors of SS Trevalgan (torpedoed by U-508 2 December 1942 southeast of Trinidad; landed at Trinidad 3 December - conflicts with DANFS Alaska chronology, see ev-03); named Tooele 15 February 1956; decommissioned 9 February 1959 at Green Cove Springs; struck from the Navy Register 1 July 1960; sold to Venezuela October 1960, never refitted, used for spare parts and later scrapped. Specifications: 280 t light / 450 t full; 173'8" x 23' x 10'10"; 20.2 kts; complement 65; armament 1x3"/50 DP, 1x40mm, 3x20mm, 2 rocket launchers, 4 depth-charge projectors, 2 depth-charge tracks; propulsion 2x Fairbanks Morse 38D8-1/8 diesels (1,440 bhp each; serials 832265/832266), Westinghouse single reduction gear, 2 shafts. NARA photograph 80-G-443973 places the ship at Dutch Harbor, Alaska, c. June 1943.

- 43 rescued merchant mariners and gunners (if attribution correct)
- Limitations
- DISPUTED: DANFS places this hull in Alaskan waters (Kodiak/Seward, then Aleutians) continuously September 1942-February 1943, which makes a December 1942 Trinidad rescue impossible under the official narrative. The rescue credit derives from merchant-side records compiled by uboat.net; the ship's December 1942 deck log (NARA-held, not digitized) is the adjudicating source. Carried as a documented conflict, not resolved. uboat.net is a specialist reference, not a government source.

- Finding
- NARA holds this hull's deck logs and has digitized the January-May 1957 file units (five monthly file units in the National Archives Catalog) - ship-specific primary records of her late-career east-coast operations out of Norfolk. The full log series (1942-1959) is NARA-held; the December 1942 volume - which would adjudicate the Trevalgan rescue conflict (see ev-03) - is not among the digitized months.

- Finding type
- asbestos_application
- Finding
- A diesel-powered steel patrol craft built 1941-42 sits inside the Navy's documented asbestos-use era; era-standard applications aboard a small combatant of this type and period were thermal insulation, machinery and diesel-exhaust lagging, gaskets, valve packing, and electrical insulation. As a diesel-driven vessel she carried no boilers or steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement contract, hazmat disclosure, or docketed case naming PC-572/Tooele was found in the public sources searched (see search_ledger). CourtListener coverage is partial: the 'USS Tooele' opinion query returned zero hits; the three remaining base queries were blocked by the fleet-wide request budget and remain pending - litigation status is an open gap, not a confirmed negative.
