USS Halibut (SSGN-587), a unique guided missile submarine turned special operations platform, later redesignated as an attack submarine SSN-587, was the second ship of the United States Navy to be named for the halibut.

Operational history

Halibut's keel was laid down by Mare Island Naval Shipyard at Vallejo, California, on 11 April 1957. She was launched on 9 January 1959, sponsored by Mrs. Chet Holifield, wife of Congressman Chet Holifield of California, and commissioned on 4 January 1960 with Lieutenant Commander Walter Dedrick in command.

Regulus Deterrence Patrols, 1960 - 1965

Begun as a diesel-electric submarine but completed with nuclear power, Halibut was the first submarine designed to launch guided missiles. Intended to carry the Regulus missile, her main deck was high above the waterline to provide a dry "flight deck." Her missile system was completely automated, with hydraulic machinery controlled from a central control station.

Halibut departed on her shakedown cruise 11 March 1960. On 25 March,[2] underway to Australia, she became the first nuclear-powered submarine to successfully launch a guided missile. She returned to Mare Island Naval Shipyard on 18 June 1960, and after short training cruises sailed 7 November for Pearl Harbor to join the Pacific Fleet. During her first deployment she successfully launched her seventh consecutive Regulus I missile during a major Southeast Asia Treaty Organization weapons demonstration. Returning to Pearl Harbor on 9 April 1961, Halibut began her second deployment 1 May. During subsequent, she participated in several missile firing exercises and underwent intensive training.

Halibut deployed for the third time to the Western Pacific in late 1961, establishing a pattern of training and readiness operations followed through 1964. On 4 May 1964 Halibut departed Pearl Harbor for the last Regulus missile patrol to be made by a submarine in the Pacific. Then, from September through December, Halibut joined eight other submarines in testing and evaluating the attack capabilities of the Permit-class submarine.

Special Operation Missions, 1965 - 1976

In February 1965 Halibut entered Pearl Harbor Naval Shipyard for a major overhaul, and on 15 August was redesignated as an attack submarine and given the hull classification symbol SSN-587. She sailed from Pearl Harbor on 6 September for the West Coast, arriving at Keyport, Washington, on 20 September. On 5 October she departed Keyport for Pearl Harbor and, after an eight-day stop over at Mare Island, California, arrived 21 October. Halibut then began ASW operations in the area, continuing until August 1968 when she transferred to Mare Island for overhaul and installation of: side thrusters; hangar section sea lock; anchoring winches with fore and aft mushroom anchors; saturation diving (mixed gas) habitat; long and short range side-look sonar; video and photographic equipment; mainframe computer; induction tapping and recording equipment; port and starboard, fore and aft seabed skids ("sneakers"); towed underwater search vehicle ("fish") and winch; and other specialized oceanographic equipment. She returned to Pearl Harbor in 1970 and operated with the Pacific Fleet and Submarine Development Group One (SubDevGruOne) out of San Diego with attachment offices at Mare Island until decommissioning in 1976.

Halibut was also used on secret underwater espionage missions by the United States against the Soviet Union. Her most notable accomplishments include:

  • The underwater tapping of a Soviet communication line running from the Kamchatka peninsula west to the Soviet mainland in the Sea of Okhotsk (Operation Ivy Bells)
  • Photography of and assistance in the recovery of a sunken Soviet submarine K-129 in the CIA's Project Azorian.

Final disposition

Halibut was decommissioned on 30 June 1976. She was "mothballed" at Keyport/Bangor Trident Base, Washington in 1976, subsequently stricken from the Naval Vessel Register on 30 April 1986, and disposed of through the Ship-Submarine Recycling Program at Puget Sound Naval Shipyard, Bremerton, Washington, on 9 September 1994.

Awards and Commendations

Presidential Unit Citation – 1968

For exceptional meritorious service on support of National Research and Development efforts while serving as a unit in the Submarine Force, U.S. Pacific Fleet.
