"Twining" was on picket station off Iwo Jima on 19 February, D-Day, as the carrier force launched strikes and fighter cover for the landings on Iwo Jima. Four days later, the destroyer again headed north protecting carriers steaming toward the Japanese homeland, but bad weather foiled the carriers. On 1 March, the task group launched strikes on the Ryukyus before steaming to the Carolines.
