Thereafter, for more than 16 years, she alternated operations on the west coast of the United States with tours in the Far East resupplying ships serving in the Orient. Among the highlights of her service was her participation in Operation Passage to Freedom, the evacuation of thousands of Vietnamese refugees from communist-controlled areas of Vietnam after that country had been partitioned in 1954. During the early years of her career, she was considered to be a pioneer in the development of improved and faster methods of fleet replenishment. To help her achieve this end, she received many alterations and tried out a great deal of experimental logistical equipment. The ship again visited Vietnamese waters in March 1965 and, for a bit over three and one-half years thereafter, devoted most of her efforts to supporting American warships fighting aggression there. She left that war-torn country for the last time on 19 April 1969 and headed—via Sasebo, Japan—for home.
