Her repairs completed, the warship conducted antisubmarine warfare patrols and participated in landing and bombardment exercises near Pearl Harbor during the latter half of May. She got underway on 29 May for Eniwetok, the staging area for the invasion of the Marianas. On 11 June, she set out for Saipan in the Northern Attack Force and spent D-Day, the 15th, in the transport screen. For the next month and a half, the destroyer patrolled the waters surrounding Saipan and Tinian on radar picket station, occasionally providing fire support and illuminating fire to help troops fighting ashore.
