With the Marshalls and Gilberts secured, the fast carrier task force embarked on a series of raids in the central Pacific to prepare for the upcoming attack on the Mariana Islands. The fleet sortied from Majuro, its new base in the Marshalls, in late March to begin the first attack on Palau and Woleai, conducted from 31 March to 1 April. During these operations, "North Carolina" shot down a Japanese aircraft. The fleet then sailed south to support the US Army's landing at Hollandia during the New Guinea campaign from 13 to 24 April. Another attack on Truk followed on 29–30 April; "North Carolina" shot down another Japanese aircraft during the attack. Two of her Kingfishers were sent to rescue a downed pilot who had crashed off the reef; one of them capsized on landing and the second was unable to take off with the additional weight from the first plane's crew and the pilot they had gone to pick up, so the submarine picked up the men instead. On 1 May, "North Carolina" and six other battleships organized as TG 58.7 bombarded Pohnpei, destroying Japanese artillery batteries, anti-aircraft guns, and damaging the airfield on the island. TF 58 then returned to its bases in Majuro and Eniwetok on 4 May; from there, "North Carolina" departed to Pearl Harbor for repairs to her rudder.
