Original caption: "West Coast Cruisers Capable of Nuclear Assault -- A Regulus I boils white smoke from booster charges as it roars away from its launcher aboard the heavy cruiser USS Los Angeles off San Diego. The launch, a routine evaluation 'shoot', was conducted during the time that 600 members of the Institute of Aeronautical Science were embarked aboard the attack carrier USS Ticonderoga (CVA-14), right. The demonstration, which included a 'Terrier' guided missile interception of the Regulus, power exhibition, carrier operations, and a HUK exercise, was highlighted by the Regulus launching. The Terrier was fired at the Regulus from the USS Norton Sound (AVM-1), background, on August 7."
