- Register-derived record: CORKWOOD ordered 12 May 1942, keel 18 Aug 1943, launched 29 Mar 1944, commissioned 16 May 1944 at Everett-Pacific SB, Everett WA. Decommissioned 7 Mar 1946, stricken 20 Mar 1946, disposal (MC/D) 18 Jun 1947, MA sale 18 Jun 1947. Ship note: 'Ex YN-63 20 Jan 44. Sold (delivered) by MC to Walter H. Wilms, Detroit, Mich.' Class data (AILANTHUS AN-38 design, Navy YN-57/AN-38): 1,175 t light / 1,460 t limited; 194.5' oa x 37' x 13.5'; diesel-electric, 1 screw, 1,200 hp; 12.1 kt; original armament 1-3"/50, 2-20mm; class complement 43 (1944). Class notes: wood hulls substituted for steel ca. 10 Apr 1942; CNO directed construction of YN 57-66 (later AN 38-47) for the British on 30 Sep 1941, but the UK allocation was reduced to five units (AN 73-77) and YN 57-66 delivered to the U.S. Navy; YN 57-66 were awarded to Everett-Pacific in May 1942 replacing cancelled PCE contracts. Same class page documents Wilms as a repeat surplus-vessel buyer: Manchineel (AN-54) 'Sold (awarded) by MC to Walter H. Wilms, Detroit, Mich.'; Viburnum (AN-57) 'Sold (delivered) to Walter H. Wilms & Co., Detroit, Mich.'

John Lester Driggs, USNR (to 21 Feb 1945), then LT. Paul Joseph Vidani Jr., USNR (to 10 Feb 1946), then LTjg. Alexander S. Abbott, USNR (to decommissioning 7 Mar 1946). Asiatic-Pacific campaign: Okinawa Gunto operation, assault and occupation of Okinawa Gunto, 26 March - 30 June 1945. Decommissioned 7 Mar 1946 'at San Pedro, CA'; transferred to the War Shipping Administration 13 Mar 1946; 'Struck from the Naval Register in June 1947'; one battle star; final disposition 'fate unknown.'

- Volunteer-compiled archive - authoritative for the compiled register/photo data it cites but is itself a secondary compilation. Three conflicts with register-derived/DANFS data carried in the correction row: 'laid down 1944' typo (1943 controls), 'struck June 1947' (register-derived 20 Mar 1946 controls), 'decommissioned at San Pedro' (DANFS implies San Diego). 2,500 shp vs. register class figure 1,200 hp - noted in gaps. Machinery spec (diesel-electric, wooden hull, no steam plant) bounds the ship's insulation profile; contains no asbestos information and supports no asbestos claim.

- Finding type
- vessel_history
- Finding
- Builder-yard record: Corkwood was yard hull no. 8 of the Everett-Pacific Shipbuilding & Dry Dock Company, Everett WA, listed as 'Corkwood (YN 63) | US Navy | Net Layer | 1,100 t | 194 ft | delivered 16-May-44 | Later AN 44, sold 1947.' The yard was established in 1942 with Navy funds, was bought in 1944 by Pacific Car and Foundry, closed when the lease terminated in 1949, and its site is now part of Naval Station Everett.

- NARA deck-log inventory: Special List 44 (Named Vessels) inventories surviving Navy deck logs for Corkwood (AN-44) covering 5/16/1944 - 6/30/1945 - i.e., commissioning day through the end of the Okinawa campaign month; these are surviving-log dates, not commissioning/decommissioning assertions. Corkwood does not appear on NARA's 'Navy Deck Logs Available in the National Archives Catalog' index (the digitized-logs list, ~1,300 vessel entries checked), so these WWII logs exist on paper at Archives II (RG 24) but are not digitized. NavSource's published commissioning-day first log entry independently confirms the logs' existence.

- Finding
- Source discrepancies resolved against register-derived and DANFS records: (a) Laid-down year - NavSource prints '18 August 1944,' impossible given the 29 March 1944 launch; NavalCoverMuseum ('keel laid August 18 1943') and the register-derived Shipscribe table ('keel 18 Aug 43') control: 18 August 1943. (b) Stricken date - NavSource prints 'Struck from the Naval Register in June 1947' and NavalCoverMuseum 'date unknown'; the register-derived record gives 20 March 1946, consistent with the 13 March 1946 WSA transfer: adopted 1946-03-20. (c) Decommissioning location - NavSource and Wikipedia print 'San Pedro, CA'; DANFS states the ship 'arrived at San Diego 29 November and remained there until decommissioned 7 March 1946': adopted San Diego, with the NavSource variant flagged rather than erased.

- Limitations
- Resolves publication-level discrepancies in secondary compilations; the register-derived strike date is preferred over NavSource's June 1947 because it coheres with the documented 13 Mar 1946 WSA transfer and 18 Jun 1947 MC sale. The San Pedro decommissioning variant cannot be fully excluded - ships did move between San Diego and San Pedro - but DANFS's 'remained there' wording controls. No asbestos content in any of these sources.

- asbestos_application
- Finding
- Era/class inference: Corkwood was built 1943-44 at a Navy-funded emergency shipyard (Everett-Pacific, established 1942 with Navy funds) during the period when asbestos was a standard insulation and fireproofing material in U.S. naval and merchant construction. As a diesel-electric net layer on a wooden hull, she had no boiler/steam-main insulation load; era-typical asbestos applications for a naval auxiliary of this size and type would have been diesel exhaust lagging, machinery-space insulation, gaskets and packing, electrical insulation and fireproofing materials, and friction linings on net-handling machinery.

The diesel-electric plant and wooden hull (verified ship-specific, ev-02/ev-03) mean the steam-era boiler-lagging driver does not apply; residual era-typical applications remain inference.

- No qualifying ship-specific asbestos record located: no asbestos survey, abatement record, hazmat disclosure, or docketed litigation naming USS Corkwood, YN-63, or AN-44 was found in the public sources searched (see search_ledger). This session's CourtListener queries returned only name collisions: 'Corkwood' opinions (type=o, limit 20) - 13 hits, all collisions (cork/bottle material and tariff cases, lumber references, street-address text); 'Corkwood' dockets (type=r, limit 20) - 94 hits, page reviewed: Fireside Corkwood Inc. bankruptcies (Bankr. E.D. Cal.) and 'Corkwood' street-address text in claims registers and joinder exhibits, zero vessel/Navy references. Both 'AN-44' base queries and the 'Corkwood asbestos' docket variant (run because the docket base overflowed its 20-result page) were throttled by the fleet pace limiter across spaced retries and are logged as unsearched, not assumed negative; the 2026-09-24 sibling session ran 'AN-44' opinions (112 - docket-number noise) and 'YN-63' opinions (0), all collisions.

- Absence of a located public record does not prove absence of asbestos aboard during her 1944-46 Navy service - 1943-44 Navy construction was era-typical for asbestos use in the residual applications noted. Does not establish or defeat any claim of exposure or legal eligibility. CourtListener coverage is partial this session (fleet throttle) - see ledger for exactly which cells ran; NARA deck logs (RG 24, verified extant 5/16/44-6/30/45) and the Maritime Commission sale file for the 18 Jun 1947 Wilms transaction remain unsearched in paper form.

(b) RG 38 war diaries if filed (none surfaced in digitized form). (c) RG-19 BuShips construction photographs of Everett-Pacific hull no. 8 (NavSource displays BuShips-attributed photos of this ship, so the class file exists).

(e) U.S. Maritime Commission/War Shipping Administration disposal and sale file for the 18 June 1947 transaction with Walter H. Wilms, Detroit - would document delivery terms and whether the sale was for scrapping, which bounds the hull's end-state.
