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.
