"Charrette" sailed from New York on 20 September 1943 to escort the aircraft carrier to Pacific service. Arriving at Pearl Harbor 9 October, "Charrette" took part in training exercises until 10 November, when she put to sea with Task Force 50 (TF 50), for air raids on Japanese bases in the Marshalls. These strikes neutralized enemy air opposition to the landings at Makin and on Tarawa which followed. On 26 November, "Charrette" joined the screen of the task group assigned to air-cover operations over Makin and Tarawa, providing protection for the transports and supplying Naval Gunfire Support (NGS). Twelve days later, the destroyer screened battleships in a shore bombardment on Nauru, before rejoining the fast carrier task force sailing on to Efate. "Charrette" sailed on 21 December to screen the carriers as they launched strikes against Kavieng, New Ireland, during the three days preceding the assault on Cape Gloucester 26 December. Continuing north, the group arrived at Funafuti 21 January 1944 to prepare for the operations against the Marshall Islands.
