"Walker" returned to Pearl Harbor during March 1952 and conducted type training and routine exercises for the next several months. On 2 June, the escort destroyer sailed for her second western Pacific deployment. From that time until 29 December 1963, "Walker" completed nine such deployments. These very active years were spent, for the most part, conducting antisubmarine warfare exercises and various operations with her task group and elements of the Republic of Korea Navy and the Japanese Maritime Self-Defense Force. "Walker"'s many "People to People" visits during this period helped to spread American good will abroad. Highlights of these years included assistance to the town of Koniya, Amami Ōshima, which had suffered major damage from a raging fire in September 1958 and as a recovery ship for a Project Mercury space flight on 28 September 1962.
