- The printed year 1943 conflicts with contemporaneous Seventh Naval District records that still carry the hull as 'PC-488' into March 1945 and first show 'Eureka (IX 221) ex-PC 488' in May 1945 - treated as a typographical error, see correction row ev-uss-eureka-ix221-02.

PC-488 change in status contemplated' and 'U.S.S. PC-488 change in status' (Mar-Apr 1945); May 1945 'U.S.S. Eureka (IX 221) ex-PC 488 placed out of commission'. The hull is consistently 'PC-488' through March 1945 and first appears as Eureka (IX-221) in May 1945.

A 'reduced commission' period Dec 1944-May 1945 is documented but its exact status (crew aboard, activity) is not in the index.

- PC-461-class program context: 421 vessels ordered, 60 cancelled, 361 delivered; designed primarily for anti-submarine warfare, convoy escort, and coastal patrol, releasing fleet destroyers for trans-Atlantic convoy duty; effective protecting convoys along the Atlantic seaboard, Caribbean, and South Atlantic during the 1942-1943 Battle of the Atlantic.

- Peer-reviewed historical study documents that asbestos was used extensively as a fireproofing and insulating material in U.S. shipbuilding during WWII - the era and program under which this PC-461-class patrol craft was built (laid down March 1941, commissioned August 1942) - and that the federal government had reserved the asbestos supply for shipbuilding, driving extensive utilization aboard naval and merchant hulls.

- Finding type
- asbestos_application
- Finding
- Era-consistent asbestos-carrier inference for this hull type: a 173-foot steel-hulled diesel-powered patrol craft built 1941-42 under wartime naval construction when asbestos was a standard, supply-reserved shipbuilding material. Because PC-488 had no boilers or steam plant (two Hooven-Owen-Rentschler R-99DA diesels), the boiler/steam-lagging pathway typical of steam vessels does not apply; era-typical asbestos carriers for a vessel of this type and period are engine exhaust lagging, machinery gaskets and packing, electrical insulation, fireproofing compounds, deck coverings, and winch/windlass brake linings.

- Finding
- The HyperWar IX index row for IX-221 reads 'Eureka, comm. 1945, Converted from Sub Chaser PC-1124' - a table error. PC-1124 in fact became Chocura (IX-206), damaged off Leyte 24 November 1944, reclassified 20 February 1945, and sunk as a hulk off Manus October 1945. IX-221 Eureka is ex-PC-488 per DANFS (ev-01), contemporaneous 7ND records (ev-02), and NavSource (ev-03).
