On 15 November 1969, Gato collided with the Soviet submarine K-19 in the Barents Sea at a depth of some 200feet. The impact completely destroyed the K-19s bow sonar systems and mangled the covers of its forward torpedo tubes. K-19 returned to port for repair but the Gato was relatively undamaged and continued her patrol.[1]
She was the first nuclear-powered submarine to completely circumnavigate South America, and the first nuclear-powered submarine to navigate the Strait of Magellan during its 1976 Unitas run under the command of CDR Robert Partlow. It was on this voyage that it became the first nuclear submarine to travel through the Panama Canal.
Gato was decommissioned and stricken on 25 April 1996 and disposed of by submarine recycling.
