"Charrette"s next contribution came during the Marianas operation, for which she sailed 6 June 1944. She supported the carriers in their strikes on Guam, Saipan and Rota from the 11 through to 14 June, then turned north for strikes against the aircraft on Iwo Jima for attacks against the American landings on Saipan. As the carriers came into position on 15 June, scouting aircraft spotted a 1,900-ton freighter and "Charrette", with the destroyer intercepted and sank the Japanese ship, recovering 112 survivors. After successful strikes, "Charrette"s group sailed south to concentrate with the Fast Carrier Task Force (then TF 58) to meet the Japanese naval force known to be coming out. The air Battle of the Philippine Sea broke on the morning of 19 June and "Charrette" continued her screening, anti-aircraft and guard duties throughout the two days of action that severely diminished the remaining Japanese naval aviation threat. On the night of 20 June, she participated in a night recovery of the last strikes, flashing beacon lights and rescuing aviators who were forced to ditch through lack of fuel. On 21 June, the carrier force steamed back to cover the invasion forces in the Marianas, Guam, Rota and later the bases in the Pagan Islands and on Chichi Jima. "Charrette" fired in the bombardment of Chichi Jima on 5 August, then returned to Eniwetok.
