She joined Task Force 36 (TF 36) at Nouméa, and served from this base and Espiritu Santo in support of the consolidation of the Solomons, patrolling, and escorting convoys.

On the night of 3/4 September in company with Pringle she intercepted and sank two barges and damaged another between Choiseul and Kolombangara while patrolling to block Japanese movements by water.

On the second of these, on 22 February the destroyers sank two cargo vessels, a destroyer-minelayer, a patrol craft and two barges, and Dyson captured 31 of the 73 prisoners of war taken from Claudia Maru.

After replenishing at Majuro, she sortied with TF 58 again in June for preinvasion strikes on Saipan and Pagan and diversionary raids on the Bonins, screened the carriers during the Battle of the Philippine Sea, then began direct participation in the capture of the Marianas.

Two days later Secretary of the Navy, James V. Forrestal presented Destroyer Squadron 23 with the Presidential Unit Citation for their outstanding performance in action in the Solomons in 1943–44.

Reporting to the Naval Base at Charleston, South Carolina, Dyson furnished electrical power for a group of decommissioned destroyers until placed out of commission in reserve 31 March 1947.
