Ship project history: The construction of this very large nuclear submarine seemed to solve the problem of low surface speed in radar-pickets: with her two-reactor plant, she had a reported speed of 27kts on the surface (but only 20kts submerged). Design features included a very large fin into which air search antennas could retract, and a large CIC for air control. She was also the first US submarine with a three-deck hull. Commissioned in 1959, she was reclassified as an attack submarine on 1 March 1961, and decommissioned 3 May 1969 as too expensive to operate and too unwieldly to be an effective attack submarine. Proposals to use her as an alternative National Emergency Command Post Afloat (as in the cruiser Northampton) were abandoned; she was the first nuclear-powered warship to be laid up.

Modernizations: None.

Naval service: No significant events.
