- Lt. Col. Edward C. Dunn, commanding the ~130-man Detachment, 4th Cavalry Group (4th and 24th Cavalry Reconnaissance Squadrons, Mecz), recorded: 'Where were you at midnight on June 5, 1944? Aboard U.S.N. Patrol Craft 484' and 'June 6, 1944? On the Ile de Terre off Utah Beach, Normandy.' The enclosed operation narrative states the detachment's 'command group [was] aboard US sub-chaser, PC-484'; that 'with PC-484 in the lead, task force then proceeded through unswept waters toward Iles St. Marcouf' for the H-minus-2-hours (0430) 6 June 1944 seizure of the two islands flanking the Utah Beach boat lanes; and that PC-484's antiaircraft guns returned fire and drove off attacking German fighter aircraft en route to the objective. The detachment took the unoccupied but heavily mined islands; total operation casualties nineteen.

- asbestos_application
- Finding
- Era inference: a diesel-powered PC-461-class submarine chaser built 1941-42 carried no boilers or steam plant, so the boiler/turbine lagging pathway documented on steam vessels does not apply; era-standard asbestos applications aboard small diesel combatants of this period were engine and exhaust lagging in machinery spaces, gaskets and flange packing, valve stem packing, electrical insulation, and fireproofing in magazine and galley spaces. No primary document specifies the insulation materials actually installed aboard this hull.

- Finding
- Widely repeated official framing for USS Cooperstown (LCS-23, commissioned 6 May 2023) calls her 'the first naval ship named after Cooperstown, N.Y.' Precision note for this hull: PC-484 was administratively named Cooperstown on 15 January 1956 while decommissioned in the Atlantic Reserve Fleet, so LCS-23 is the second Navy hull to carry the name but the first to serve in commission under it - PC-484 never operated as 'Cooperstown.'
