"Nevada" then returned to the United States to have her badly-worn barrels relined before returning to the Pacific Fleet. She arrived in the advance base at Ulithi in January 1945 and began preparations for the next major operation, the landing at Iwo Jima the following month. She joined several other battleships for an intensive bombardment of the island for three days before the Marines went ashore on 19 February. The ship operated off the island providing fire support through 7 March, when she departed to prepare for the invasion of Okinawa. The initial bombardment began on 24 March and continued until the landing on 1 April, and "Nevada" remained off the island until 14 April when she was withdrawn for an overhaul. The ship returned for patrols in the East China Sea in July, though she saw no further action before the end of the war on 15 August.
