Returning to Majuro 6 April 1944, "Frazier" sailed a week later with a fast carrier task group for attacks on Wakde Airfield and Sawar Airfield in Western New Guinea, on 21 and 22 April, to neutralize the danger of air attack on the Landing at Aitape and the Battle of Hollandia. The task group also struck at targets in the Caroline Islands as it sailed back to arrive at Kwajalein 4 May. From 10 May to 27 July, "Frazier" patrolled the bypassed Japanese-held islands in the Marshalls, which included Wotje, Jaluit, and Mille. She bombarded Mille on 26 May, and on 9 June sent her motor whale-boat in under the guns of Taroa to rescue 10 survivors of a flying boat previously sent in to rescue a downed aviator and were stranded when their plane was damaged by a shore battery. Two weeks later she rescued two Marine aviators off Mille.
