In 1943, "Saratoga" supported Allied forces involved in the New Georgia Campaign and invasion of Bougainville in the northern Solomon Islands and her aircraft twice attacked the Japanese base at Rabaul in November. Early in 1944, her aircraft provided air support during the Gilbert and Marshall Islands Campaign before she was transferred to the Indian Ocean for several months to support the British Eastern Fleet as it attacked targets in Java and Sumatra. After a brief refit in mid-1944, the ship became a training ship for the rest of the year.
