Nine "Balao"s were lost in World War II, while two US boats were lost in postwar accidents. In foreign service, one in Turkish service was lost in a collision in 1953, one in Peruvian service was lost in a collision in 1988, and was sold to the Argentinian Navy. She was renamed the ARA "Santa Fe" (S-21) and was lost in the 1982 Falklands War after being damaged, when she sank while moored pierside. "Santa Fe" was refloated and disposed of a few years after the war by being taken out to deep water and scuttled.
