Between January 1948 and June 1950, "Agerholm" alternated two WestPac deployments with operations out of San Diego. Upon her return to San Diego in June 1950, she commenced overhaul at Mare Island, California, while other ships steamed to Korea as part of the United Nations task force defending South Korea from the aggression of her northern counterpart. Completing her overhaul in late 1950, "Agerholm" trained for war and set a course for the Far East. She entered the combat zone on 19 February 1951 and was assigned to Task Force 77 as screening ship and plane guard. The destroyer also aided in shore bombardment, training her guns on Wonsan on 28 April and 1 to 4 May, and on Kojo on 29 April. "Agerholm" returned to San Diego on 20 September for upkeep and local operations.
