Her force launched prelanding strikes at Okinawa and nearby islands, and after the landings on 1 April 1945, supported the ground forces and protected the transports. "Chauncey" continued her screening, and from 6 April, when the first great "kamikaze" attacks were hurled at American shipping off Okinawa, fired often to drive the would-be suicides off. She also served in shore bombardment and radar picket duty until 29 May, when she sailed for repairs and replenishment in San Pedro Bay, Philippine Islands. She then joined Task Force 38 for the final smashing air raids on Japan.
