Triton was a first generation U.S. nuclear-powered submarine.  It was designed in the 1950’s to be a “radar picket” submarine to provide electronic surveillance and intelligence information for forward-deployed naval forces.

After operating for only two years, Triton‘s role as a radar picket submarine was made obsolete by the introduction of carrier-based early warning aircraft and she was converted to an attack submarine in 1962. She was decommissioned in 1969, becoming the first U.S. nuclear submarine to be taken out of service.
