- NavSource is a volunteer secondary compilation, not a primary registry - its milestone dates generally track official records and the construction/transfer/fate dates here are corroborated by the builder's production list (ev-05). Contains no asbestos content. 'South of Quemoy Island' is a loose location descriptor - ROC accounts place the sinking ~25 nm southeast of Dongshan Island (see gaps).

- Finding
- PC 1232 appears by name in the Normandy invasion operation plan: Annex L, 'Voice Call Signs for use on voice circuits within the Western Task Force' (Table II), assigns PC 1232 call sign 8B3 - placing this hull on the Western Naval Task Force (TF 122, the US force covering the Omaha and Utah assault areas) communications net for Operation Neptune alongside assault transports, minecraft, and escorts. Her own action report (ev-02) places her in the Utah Transport Area under CTG 122.4.

- Finding
- Builder documentation for this hull: Fred Sullivan leased the repair yard at the head of Brooklyn's Tebo Yacht Basin (foot of 22nd, 23rd and 24th Streets) from Todd Shipyards in 1937, renamed it Sullivan Dry Dock & Repair Co., converted it to new construction, and it closed in 1947. The production list records fifteen PC-461-class subchasers built for the US Navy (plus smaller craft); the PC-1232 row reads 280 LDT / 174 ft, delivered 18 August 1943, 'to Taiwan 1954 as Chang Kiang (PC-118), sunk by PRC 6-Aug-65' - corroborating the NavSource timeline for this hull.

- ROC service and loss of this hull: transferred to the Republic of China June 1954 and renamed Chang Kiang (PC-118); sunk in action 6 August 1965 in the Battle of Dongshan (Ba Liu Hai Zhan, 'August Sixth' naval battle) - Chang Kiang and patrol ship Chien Men (ex-USS Toucan, AM-387) were sunk southeast of Dongshan Island by PLA Navy gunboats and torpedo boats during ROC operation 'Tsunami No. 1' (Project National Glory intelligence-landing operation). Per the ROC account, Chang Kiang took concentrated armor-piercing fire below the waterline, exploded and sank about 0330 roughly 25 nm SE of Dongshan Island; combined ROC losses were roughly 170 killed including task-force commander Rear Admiral Hu Jiaheng, with 33 captured (including Chien Men's CO, Commodore Wang Yunshan).

Sullivan Drydock & Repair Corp., 328 U.S. 275 (1946), the Supreme Court's veteran-reemployment seniority decision, places a welder employed at this yard from 1942, inducted into the Army 1943, and reemployed as a welder 25 August 1944 - documenting welding trades at this builder during this hull's construction window. (b) Oceanic Insul-Lite Corp. v. Sullivan Dry Dock & Repair Corp., 191 Misc. 354 (N.Y. Sup. Ct. 1947), a contract dispute over $5,818.75 claimed due for 'work, labor and services performed, and materials furnished for the repair and conversion of a certain steamship' - documents an insulation contractor performing ship work for this yard in the era.

Fishgold is an official U.S. Reports citation; Oceanic is cited by reporter only - the located online mirror (hallapproved.com) is a blocklisted aggregator per batch citation rules.

- Finding type
- asbestos_application
- Finding
- A steel-hulled twin-diesel patrol craft built 1942-43 at a Brooklyn commercial yard sits inside the Navy's documented asbestos-use era; era-standard applications aboard a vessel of this type and period were machinery and diesel-exhaust lagging, gaskets, valve packing, electrical insulation, and interior thermal/acoustic insulation in small enclosed spaces. As a diesel craft she carried no steam plant - the boiler/turbine lagging pathway of steam vessels does not apply.

[10]GAO, Navy Efforts To Protect Workers From Asbestos Exposure, HRD-80-2 (Oct 18, 1979; publicly released Oct 22, 1979) [gao]

- GAO product page HRD-80-2, Highlights section
- Finding type

- Finding
- GAO reviewed Navy efforts to protect workers from asbestos exposure (fieldwork at Long Beach and Norfolk Naval Shipyards), covering '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 selective replacement in high-maintenance areas - confirming extensive asbestos insulation use aboard Navy ships through the era spanning this hull's construction and service.

No DANFS entry exists for this hull (NavSource so notes; NHHC URL 404). CAVEAT: CourtListener could not be queried this session - the helper script reported the fleet daily quota exhausted with a ~2-hour server-requested wait (a multi-hour wait = daily quota spent under batch rules); logged as blocked, not as a negative result. Secondary web sweeps surfaced no qualifying case and no law-firm marketing claims naming this hull.
