In June, the submarine transferred administratively from SubRon 1 to SubRon 7; and, in July, she headed west once more for a tour in the Far East. Again, training exercises predominated with "Wahoo" serving as target in ASW practice and participating in several fleet exercises. She returned to Oahu at the beginning of 1960 and, after two months of normal operations once again entered the Pearl Harbor Naval Shipyard this time for a major overhaul. Exiting the yard in late August, she conducted refresher training and then resumed her normal schedule of operations in the Hawaiian Islands.
