next 16 years, Segundo operated out of her home port and along the west coast. From 1953 through 1969, she was deployed to the western Pacific every year except 1961, and 1963. Segundo departed for the Western Pacific Ocean on 27 November 1956 with stops in Pearl Harbor, Yokosuka, Japan, Hong Kong, China, Subic Bay and Manila, Philippines and Buckner Bay, Okinawa. The reason for this emergency departure was because of the Hungarian revolt that was taking place at the time. The Segundo was ordered into port in San Diego and shortly after departed for Peal Harbor, then the north Pacific on a special patrol, submerging on 21 December 1956 and resurfacing on 21 January 1957 before stopping in Yokosuka Japan. In July 1970, a Survey Board found Segundo unfit for further naval service. The submarine was decommissioned 1 August 1970, struck from the Navy list on 8 August 1970, and sunk as a target by either the submarine or the submarine (sources differ). Honors and awards Segundo received four battle stars for World War II service and one for the Korean War. References Citations Bibliography Hinman, Charles R., and Douglas E. Campbell.
