the 24th. Aylwin returned to Majuro on 4 May for tender repairs alongside which ended on the 21st. After screening Bunker Hill and Cabot during training in late May and early June, the veteran destroyer departed Majuro on 6 June bound for the Marianas Islands in company with TF 58. On the 12th, the planes from the carriers bombed air facilities and coast defenses in the Marianas and damaged two Japanese convoys. On the 13th, Aylwin was part of the Northern Bombardment Unit (TU 58.7.2) which shelled defense positions on the northern coast of Saipan and also served in the antisubmarine screen for the battleships and South Dakota. When the shelling ended at 17:15, she rejoined the carriers and guarded them as they refueled the next day. During that operation, the destroyer received orders to rescue a pair of Bunker Hill aviators and, less than an hour later, picked up Ens. G. W. Snediker, USNR, and Aviation Radioman 3d Class R. E. Lincoln, USNR. The destroyer made another rescue on the 16th while covering the cruiser bombardment of Guam when a plane piloted by Ens. F. P. Kleffner, USNR, crashed 1800 yards astern. On the 17th, Aylwin was ordered to help screen the transports, and she missed the Battle of the Philippine Sea on the 19th and 20th which almost wiped out Japanese carrier-based aviation. Aylwin next proceeded to Eniwetok where she arrived on 28 June for a fortnight's upkeep. Aylwin screened and as those cruisers shelled installations on Guam on 18 and 19 July before taking part in a bombardment of the northern shores of the island, concentrating her fire on Japanese defensive positions near Asan Beach. At the outset of the mission, Dewey and two LCI's provided harassing fire into that area. and Dewey stood in close to the beach, lying close to Adelup Point and covered the night beach obstruction demolition work of underwater demolition teams (UDTs), screened to seaward by Aylwin, Dale, and . Aylwin relieved Dewey on station on 21 July, off Asan Beach. Dale in turn relieved Aylwin on station. Relieved at 05:30, Aylwin and her colleagues retired to the transport screen northwest of Orote Point and Agana Bay. On 25 and 26 July, the destroyer screened a cruiser bombardment of Rota Island and departed the area on the 30th, bound for Eniwetok on the first leg of a voyage home. Aylwin stopped at
