On 4 July, one of "Indiana"s Kingfishers picked up two men from the carrier after their aircraft had gone down. "Indiana" remained off the Marianas until early August when she was detached to Eniwetok to replenish ammunition and supplies. She got underway on 30 August with TF 34 and met TG 38 on 3 September, which was scheduled to attack the Palau Islands later that month. "Indiana" developed engine problems, however, and she was sent to Seeadler Harbor for repairs that lasted from 21 September to 4 October. During this period, Davis shifted his flag to "Massachusetts". "Indiana" then joined the battleship and the cruisers and for the voyage to Pearl Harbor. They arrived there on 14 October, and two days later "Indiana" and "Idaho", escorted by two destroyers, left for Puget Sound Navy Yard for a thorough overhaul that was completed on 30 November. Following another round of sea trials, "Indiana" left on 6 December, bound for Pearl Harbor, where she conducted training exercises and additional repairs that lasted through the end of the year.
