US NAVY SUBMARINE ACCIDENT SERIES

Repairs took two weeks.Īccording to the documentary 'Regulus: The First Nuclear Missile Submarines' the primary target for Grayback in the event of a nuclear exchange would be to eliminate the Soviet naval base at Petropavlovsk-Kamchatsky. Main propulsion was lost for a short time, was restored, and Grayback returned to Pearl Harbor under her own power. One seaman failed to evacuate the compartment and was overcome by smoke and fumes. The buffeting caused the After Main Battery breaker to short, starting a fire in the berthing compartment. On 27 August 1963, while snorkeling to recharge batteries, Grayback was buffeted by particularly strong seas. On her nine patrols she spent more than 20 months at sea and logged over 130,000 miles (209,000 km) on deterrent missile strike missions. In addition to Yokosuka, both Adak, Alaska, and Pearl Harbor also served as termination points for these patrols. Over the next 2½ years she completed seven missions for a total of nearly 18 months at sea, much of this time submerged.

After this, she again took up deterrent missile strike missions. On 22 February 1960, Grayback modified her missile launching system and simplified her complex electrical circuits. Grayback 's first patrol terminated at Yokosuka, Japan, as did two others. This was followed by the first of her nine deterrent missile strike missions, from 21 September to 12 November.

After a series of exercises there, she cruised to Dutch Harbor, Umak Island, Sequam Island, and Kodiak, Alaska, for further missile exercises from 3–31 July. On 9 February 1959, Grayback departed Mare Island to make Pearl Harbor her permanent home base, reaching Hawaii on 7 March via Port Hueneme, California, Long Beach, California, and Mazatlan, Mexico. Departing San Diego, California, on 30 October, Grayback arrived at Pearl Harbor on 8 November for a month of exercises and maneuvers before returning to Mare Island for her '10,000 mile checkup.' Regulus II was cancelled in December 1958 except for test firing of missiles already built, so Grayback operationally deployed with four Regulus I missiles. While operating out of Naval Base Ventura County in Port Hueneme, California, in September 1958 she conducted the first successful launching of a Regulus II missile from a submarine, whose predecessor, Regulus I, had led to the capability of navies to attack land bases since its deployment in 1957. In 1958, Grayback conducted tests and shakedown along the West Coast. Grayback represented a new class of SSG guided missile submarines, and was to be the first to carry the Regulus II sea-to-surface missile.

Operational history Guided missile submarine Grayback prior to launch Grayback preparing to launch a Regulus II missile Grayback was initially designated as an attack submarine, but was converted in 1958 into a guided-missile submarine (SSG-574) armed with the Regulus nuclear cruise missile.
