On the same day that she completed her overhaul, "Wahoo" departed Pearl Harbor and shaped a course for her new home port, San Diego, California. En route, she visited Portland, Oregon, and Vancouver, British Columbia. The submarine arrived at San Diego on 26 June and began type training and other local operations along the southern California coast. The change in home ports, however, did not signal an end to tours of duty in the western Pacific. Her next deployment brought with it a visit to Chinhae and Pusan in Korea and a period of combined operations with units of the South Korean Navy. Later in that cruise, she also visited Taiwan and participated in bilateral ASW exercises with units of the Republic of China Navy. She finally concluded the deployment at San Diego on 28 April 1972. After a series of brief exercises with ships and aircraft during the month of May, she entered Hunters Point Naval Shipyard for a three-month overhaul. Back at sea by the middle of September, she resumed local operations – type training, ASW exercises with surface units and aircraft, and torpedo and mine evaluation tests – for the remainder of the year.
