On 9 February 1945, she sailed out of the Golden Gate in company with and set a course for Pearl Harbor. The two warships reached Oahu on 15 February, and "Ammen" performed training and carrier escort missions in the Hawaiian Islands until the middle of the first week in March.

The three warships made one stop-at Eniwetok on the 10th for fuel-before arriving at Ulithi Atoll on 13 March.

"Ammen" and her colleague reached their destination on St. Patrick's Day 1945 and set about practicing for the invasion of the Ryukyu Islands.
