After the storm, LSM(R)-528 resumed her voyage and arrived at Charleston on 21 September. While there, the ship had her rocket launchers and mortars installed.

Departing Charleston on 12 October, LSM(R)-528 sailed for Little Creek, VA, arriving on 14 October. After leave and upkeep, she began shakedown training on 15 October.
