The new tug was assigned harbor duty in the 14th Naval District based at Pearl Harbor, and she remained there until transferred to the Philippines in 1955. At Subic Bay Iona performed harbor duties necessary for the smooth functioning of a naval base. She was reclassified a 'District Harbor Tug Medium', YTM-220, in February 1962. In June, 1963, following an accidental sinking in May, she was disposed of by burning.
