- NavSource timeline for this hull: PC-461-class submarine chaser laid down 3 April 1943 by the Consolidated Shipbuilding Corp., Morris Heights, NY; launched 15 May 1943; commissioned 6 September 1943; 'Grounded and capsized 9 October 1945 at Buckner Bay, Okinawa by Typhoon Louise'; 'Refloated and decommissioned 30 November 1945'; struck from the Naval Register 19 December 1945; transferred to the Foreign Liquidation Commission in May 1947 and sold for scrap to the Oklahoma-Philippine Co. Specifications: 280 t. (lt), 450 t. (fl); 173'8" x 23' x 10'10"; 20.2 kts; complement 65; armament one 3"/50 dual-purpose gun mount, one 40mm mount, two 20mm guns, four depth-charge projectors, two depth-charge tracks; propulsion two 1,440 bhp Hooven-Owen-Rentschler R-99DA diesel engines (Serial Nos. 7033 and 7034), Westinghouse single reduction gear, two shafts. Page hosts photographs of the hull after launching and of the capsized hulk grounded at Buckner Bay.

- NavSource is a volunteer secondary compilation, not a primary registry; milestone dates generally track NVR/DANFS but the decommission date (30 November) conflicts with the NHHC official casualty appendix (23 November) - carried in gaps. Contains no asbestos content. Page states no DANFS history exists for PC-1238, consistent with the live NHHC DANFS URL returning 404.

[3]NHHC Navy Department Library Online Reading Room, 'Typhoons and Hurricanes: Pacific Typhoon at Okinawa, October 1945' - narrative plus Appendix III ship-casualty list, extracted from the Commander in Chief, Pacific Fleet and Pacific Ocean Areas report on the Surrender and Occupation of Japan [other_primary]

- Finding
- Official Navy documentation naming this hull: in the Appendix III casualty list for Typhoon Louise (9 October 1945, Buckner Bay/Nakagusuku Wan, Okinawa) the entry 'PC 1238' reads 'Refloated 10/19/45. Capsized. Heavily damaged. Decommissioned 11/23/45.' The CinCPac report extract documents the storm's scale: winds of 80 knots with 30-35 foot waves; 12 ships and craft sunk, 222 grounded, 32 severely damaged; 36 dead, 47 missing, ~100 seriously injured; ComServDiv 104 under Commodore T.J. Keliher assigned to salvage, 79 ships refloated by 19 November; on 14 November ComServPac decided only 10 ships were worth complete salvage, similar types being decommissioned at home and salvage costs excessive for unneeded ships.

Documents that PC-1238 was operating on the U.S. West Coast plane-guard/patrol station system under the Western Sea Frontier as of 24 May 1945 - approximately four months before her loss at Okinawa.

Salvaged and decommissioned on 30 November 1945. Sold to be broken up for scrap.' Wartime commanding-officer succession listed: J. R. Kringel, USNR (6 Sep 1943 - mid 1944); Lt. (jg) Richard F. Beam, USNR (mid 1944 - early 1945); J. L. Williams, Jr., USNR (early 1945 - mid/late 1945); D. Davidson, USNR (mid/late 1945 - 9 Oct 1945).

Dates corroborate NavSource on loss and disposal; the 'ordered 21 Nov 1942' date is uncorroborated by an official source. Partial CO corroboration exists: J. L. Williams Jr. signed the 16 September 1945 muster-roll Report of Changes as 'COMMANDING OFFICER' (see ev-07) - consistent with the listed early-1945 to mid/late-1945 tenure, and implying the Williams-Davidson handoff occurred between mid-September and 9 October 1945.

Corroborates that PC-1238's war loss was an Okinawa grounding; the printed date (read literally as 8 or 9 September 1945) conflicts with the officially documented 9 October 1945 Typhoon Louise loss and is unresolved.

- A digitized primary personnel record exists and was content-sampled for this hull: NARA file unit 'PC-1238, 9/6/43-12/1/45' (NAID 192146141) - muster rolls covering the hull's entire commissioned period, 272 scanned images on microfilm reel 120-4157 (container Roll 6009), publicly viewable in the National Archives Catalog via the Ancestry digitization partnership, access unrestricted. Sampled pages verify: (1) commissioning-day Report of Changes, 6 September 1943 - plankowner enlisted men received 'From: RecSta. Bklyn, NYK' and 'From: RecSta. New York, NYK' (ratings incl. BM2c, MoMM1c, PhM1c, QM3c(SV), SoM3c(SV), StM2c(SV)); (2) Report of Changes dated April 1944 - rating advancements dated 4/1/44, Norris L. Fish, CMoMM(PA), 'Accepted appointment to Ensign, USN; transferred to 7th Nav. Dist.' dated 4/12/44, and two passengers recorded 4/18/44 'Transportation to Navy #115; Final destination Naval Air Station, Coco Solo, Canal Zone' - evidence of Canal Zone-area operations in spring 1944; (3) the Muster Roll of the Crew for the quarter ending 31 December 1943 - alphabetical crew roster with ratings and 'date first received on board' (nearly all 9/6/43 plankowners, a few 9/24/43); (4) Report of Changes upon sailing dated 16 September 1945 - three men transferred 9/13 to 'RecSta., Navy 3011 FFT' for demobilization discharge, signature block 'J. L. WILLIAMS JR. Lieut. USNR. COMMANDING OFFICER.' - primary-source confirmation of the third commanding officer in uboat.net's secondary listing. Roll terminates with an END OF REEL marker.

- asbestos_application
- Finding
- A steel-hulled patrol craft built April-September 1943 sits inside the Navy's documented asbestos era; era-standard applications aboard a diesel-driven combatant of this size and period were engine and diesel-exhaust lagging, thermal insulation of machinery and accommodation spaces, gaskets, valve packing, electrical insulation, and deck covering. As a twin-diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply, but exhaust lagging and the confined-space exposure dynamic of a 173-foot hull apply.

- Finding
- GAO documented that the Navy used asbestos insulation extensively aboard ships, reviewing 'the use of asbestos in Navy ships, the cost of removing asbestos from Navy ships, and compensation programs for asbestos-related disabilities'; the Navy's 1975 policy was to remove and replace with nonasbestos materials only insulation that was damaged or had to be removed for necessary repairs, modified in 1979 to selectively replace asbestos insulation in high-maintenance areas. Program-level confirmation that this hull's 1943 construction and 1943-45 service fell inside the Navy asbestos era.

CAVEAT: the CourtListener litigation sweep could not be completed this session - the first base query returned HTTP 429 with a ~109-minute Retry-After; the full backoff was waited out and two subsequent attempts (at the ~12:15 retry window and ~25 minutes later) both received the fleet pacer's stand-down ('the fleet-wide request budget is momentarily spent ... try CourtListener again later'). Logged as blocked in the search ledger, not as a negative result. Secondary web sweeps surfaced no qualifying case; the only 'asbestos aboard' material is law-firm marketing content asserting asbestos on WWII hulls without primary sourcing - excluded by source policy.
