Following six months duty with American occupation forces in Chinese waters, "Thompson" returned to the United States in early September 1947 and arrived at San Diego, California, on 2 October. Transferred to the operational command of Destroyers, Pacific Fleet, with the abolition of the Pacific Fleet Minecraft command, "Thompson" operated out of San Diego as a destroyer until 29 April 1948, when she returned again to Mare Island for a two-month overhaul. In July, she returned to San Diego and underwent training operations off the west coast, activities in which she was engaged for the remainder of 1948.
