In her initial engagement with the Japanese, Bataan's planes supported the attack on Hollandia, New Guinea, between 21 and 24 April 1944.

Bataan then returned to the United States for repairs. Repairs completed she joined TF 58 and participated in the fleet raids in support of the Okinawa operation (17 March-30 May 1945), during which her aircraft assisted in the sinking of the Japanese submarine I-56, 18 April 1945, in 26°42' N., 130°38' E.
