"Izard" continued in support of fast carriers launching strike after strike against the enemy. On 4 July 1944 it was in a group of three cruisers and four destroyers that bombarded the airfield at Iwo Jima. During the first part of October she joined Admiral John S. McCain's task group for strikes on Okinawa and Formosa. During the following months she supported the Leyte operation and participated in the Battle of Lingayen Gulf. There she was next to the "Columbia" (CL-56) when the "Columbia" was hit by a kamikaze. At one point, she sailed through the eyewall of a Pacific storm that had 50 knot winds. In February 1945 she was supposed to head for refitting, but another ship needed replacement as part of the Iwo Jima attack. She sailed with one other ship to Iwo Jima, arrived on the second day of the invasion, and was assigned duty during the Battle of Iwo Jima rendering fire support, screening, and radar picket duty until 27 March. She fired 3,600 five inch rounds at Iwo Jima during the battle, firing from South of the island.
