CNS Thomson (SS-22)
In April 1960, Springer was moved from Mare Island to the San Francisco Naval Shipyard to be modernized in preparation for her transfer to the Republic of Chile. She was recommissioned on 24 September and the overhaul completed on 15 November. From 19 December 1960 to 19 January 1961, she held alongside and underway training for the Chilean crew.
Springer was decommissioned on 23 January 1961, transferred to the Republic of Chile, and commissioned in the Armada de Chile as CNS Thomson (SS-22) on that date.
Springer was struck from the US Navy list on 1 September 1972, and sold to the government of Chile; she was stripped for spare parts for other submarines and her hulk sold for scrapping.
