Sevier was held in a waiting station 100 miles (160 km) off the island of Iwo Jima until 14 March, when she anchored to evacuate marines of the 4th Division who had participated in the assault.

Embarking 1,193 officers and men of the 125th Construction Battalion and 171 marines, Sevier left Pearl on 12 May with a convoy, which, after a brief stop at Eniwetok, arrived at Ulithi on 26 May.

During her two days and nights anchored off Okinawa, Sevier worked continuously unloading the Seabees and marines and their equipment.

Underway on 19 June, she witnessed the intensive air and sea bombardment of the southern end of the island, before setting course for the United States.

Sevier arrived at San Francisco on 13 July and then proceeded to the Everett Pacific Shipyard near Seattle for repairs to her propeller shaft.

Underway three days later, she arrived at Manila on 30 September and then embarked more occupation troops in Lingayen Gulf from 3 to 6 October.

Sevier was decommissioned at Suisun Bay, California, on 30 April 1947 and delivered to the Maritime Commission's National Defense Reserve Fleet there on the same day.
