Nuclear-powered guided-missile cruiser USS Long Beach. Long Beach was the world's first nuclear-powered surface warship. As designed, she was also the first warship destined to have an armament consisting solely of guided missiles, however two 5"/38cal turrets were added amidships in 1962-1963 for shore bombardment and/or antiaircraft closer-range defense (these guns had very limited arcs of fire due to their position on the vessel). Two Phalanx close-in weapon systems can be seen and the superstructure lacks the so-called billboard radars, so the photo must postdate Long Beach's 1980-1983 conversion.
