Corson departed San Diego, California, on 12 February 1945, tended seaplanes briefly at Pearl Harbor, Hawaii, and at Eniwetok, and moved on to reach Ulithi Atoll on 1 April 1945.

She then moved on to Okinawa, arriving there on 15 August 1945, the day hostilities with Japan ceased and World War II came to an end.

She tended seaplanes at Nagasaki, at Sasebo, and in Hiro Bay until 20 January 1946, when she departed for Pearl Harbor and Alameda, California, where she arrived on 9 February 1946 for inactivation.

Corson tended seaplanes at San Diego until her next tour of duty in the Western Pacific, which lasted from 8 December 1952 to 4 August 1953.

During this tour, she served as station tender at Hong Kong, conducted reserve training at Subic Bay at Luzon in the Philippine Islands, laid a seadrome in the Pescadores, acted as advance base support at Keelung, Taiwan, and served as plane guard off Indonesia for United States Air Force jet aircraft flying to Bangkok, Thailand, on a good-will mission.
