Frank Jack Fletcher
As part of Task Group (TG) 40.2, "Xanthus" proceeded to Japan and arrived at Ominato on 9 September 1945—the same date that Japanese forces there surrendered to Vice Admiral Frank Jack Fletcher. The ship remained at Ominato through 21 November, serving as flagship for the commander of TG 56.2, the repair and logistics group. Subsequently reporting for duty with Service Squadron 104, the ship operated out of Okinawa through late January 1946.
