In January 1960, "Swordfish" deployed to the western Pacific Ocean (WestPac) for four months and became the first nuclear submarine in that area. During this time, President of the Republic of China Chiang Kai-shek was embarked for a one-day indoctrination cruise. She deployed to WestPac again on 20 June and on this occasion took President of the Philippines Carlos P. Garcia to sea for a one-day demonstration. The submarine conducted local operations in the Hawaiian area from January to May 1961. In late May, the submarine got underway for the West Coast of the United States where she operated between San Diego and San Francisco, with various Pacific Fleet units. "Swordfish" returned to Pearl Harbor on 14 July and operated locally until September when she deployed to the western Pacific for two months.
