"Bataan" spent most of November and December conducting pilot training exercises and night-fighter operations in Hawaiian waters. Seven aircraft were lost in accidents, including one Wildcat that crashed into her number 2 stack but only two pilots were injured. In January and February 1945, the focus of training operations shifted to night-fighter direction and ground-attack exercises. Accidents claimed another five aircraft, including a Vought F4U Corsair fighter that burned on the flight deck on 28 January 1945, but again no pilots were lost. The carrier entered the Pearl Harbor Navy Yard on 16 February, undergoing repairs to her flight deck and receiving three new 40-millimeter antiaircraft guns.
