On February 20 1944, AWS-1 landed on Engebi as part of the larger Gilbert and Marshall Islands campaign. The squadron set up its SCR-270 and SCR-527 radars and took control of the airspace over Eniwetok on March 1, 1944. During its time on Engebi the squadron worked closely with the 10th Defense Battalion to ensure the aircraft it controlled were properly deconflicted from the battalion's air defense fires.
