In late December 1950, "Hoquiam" assisted with harbor control operations during the evacuation at Hungnam before leaving for Japan. Arriving at Yokosuka on 30 December 1950, she underwent a brief overhaul, then served as a drone target ship off the coast of Japan from late January until early March 1951. She returned to Korean waters on 8 March 1951 and over the next six months operated along the east coast of Korea from Wonsan to Songjin. She participated in interdiction and harassment patrols designed to destroy enemy coastal shipping, conducted antisubmarine warfare operations off Wonsan, and bombarded enemy shore installations and coastal supply routes.
