June. She then patrolled in the East China and Yellow Seas, sinking two junks by gunfire before returning to Saipan on 18 July. The submarine sailed for Hawaii the next day. Spot arrived at Pearl Harbor on 29 July for an extended overhaul and was still there when hostilities ceased. She sailed for San Diego on 27 August and provided services for antisubmarine warfare units there from 3 September 1945 to 2 March 1946. The ship then sailed to San Francisco to prepare for inactivation. She was decommissioned at the Mare Island Naval Shipyard on 19 June and attached to the Pacific Reserve Fleet. Honors and awards Spot received four battle stars for World War II service. Chilean Navy service In January 1961, Spot was towed to Pearl Harbor for modernization in preparation for transfer to the Chilean Navy. A streamlined sail was added but, unusually for a post-World War II submarine, her deck gun was retained. The Chilean crew reported aboard later in 1961 for training, and on 12 January 1962, Spot was loaned to that government under the Military Assistance Loan Program. She was renamed Simpson (SS-21), in honor of Chilean admiral Robert Winthrop Simpson (1799–1877). The submarine arrived in Chile on 23 April 1962. On 1 August 1975 the submarine was sold outright to Chile, and struck from the US Navy Directory. In 1980, Simpson was used extensively by director Kinji Fukasaku in the disaster film Fukkatsu no hi (titled in EnglishVirus and Day of Resurrection). The film features spectacular footage of Simpson operating in the Antarctic. Simpson was significant for being one of the last submarines to have a deck gun; she was disposed of by the Chilean Navy in 1982. References Citations Bibliography Hinman, Charles R., and Douglas E.
