"Gainard" operated as radar picket and fighter director ship throughout the bloody Okinawa Campaign, detecting enemy air raids, providing early and continuous information to friendly forces, and initiating interception with a Combat Air Patrol unit that found her controlling an average of 10 planes from dawn to dusk with the assistance of a fighter director team on board. In 39 days on picket stations, she was instrumental in the destruction of at least 27 "kamikaze"s, 5 of which were shot down by her gunners.
