Twining patrolled off Nafutan Point, two enemy planes attempted to make runs on Aslito airfield but were turned back by heavy fire from the destroyer. Into July, Twining continued her duties off Saipan, supplying screening, fighter direction, and fire support. She also made occasional voyages to Tinian for bombardment missions. Off the northern tip of Saipan on the night of 6 and 7 July, Twining'''s crew was kept busy firing on numerous Japanese airplanes which had apparently chosen the ship both as a reference point for their approach to the runway on Marpi Point and as a target for their bombs. Nine planes made approaches during this raid, although only one dropped a bomb. Flares from the planes often illuminated the scene as the destroyer's gunfire drove off all nine, none of which managed to land on the Japanese-held airstrip. In the days that followed, Twining remained on picket station, occasionally firing on enemy troop concentrations on the island. On 24 July, she screened Montpelier and as they shelled Japanese positions on Tinian. The following day, the destroyer fired support missions to screen American troops advancing up the western shore of the island. Twining continued her support of the invasion of Tinian through the end of the month, steaming on station between Tinian and Saipan and occasionally firing at Japanese targets on the island. On 1 August, Twining moved to a new fire support assignment off the southeast coast of Tinian. She made the first of three bombardment runs at 01:30 and later stood into 1,500 yards from shore to pound enemy-held slopes and caves with gunfire. On the 7th, Twining departed Saipan, escorting slow-moving LST-130 to Eniwetok. A week later, she entered the atoll where her worn strut bearings were replaced.Twining departed Eniwetok on 15 September to rendezvous with Rear Admiral Gerald F. Bogan's Fast Carrier Task Group (TG 38.2) and thereafter devoted most of her effort for the rest of the war to protecting aircraft carriers. Arriving off Luzon on the 21st, Twining guarded the carriers as they launched strikes despite cloudy weather, squalls, and low visibility. Following the launching of further strikes from an attack position off San Bernardino Strait on the 24th, the task group headed eastward and arrived off Saipan on the 28th. From there, the destroyer conducted antisubmarine patrols until the 30th when the task group got underway for the western Carolines and entered
