The second Sam Houston (SSBN-609) was laid down on 28 December 19.~9 by the Newport News Shipbuilding and Dry Dock Co., Newport News, Va.; launched on 2 February 1961; sponsored by Mrs. John B. Connally, and commissioned on 6 March 1962, Capt. W.P. Willis, Jr., (blue crew) in command.
Following shakedown, the nation's seventh Polaris submarine fired her first missile on 25 April off Cape Canaveral, Fla. The gold crew, commanded by Comdr. J. H. Hawkins, then took over, completed its missile firing on 11 May 1962 and then departed from Cape Canaveral for its own shakedown training.
On her first patrol, Sam Houston, manned by the blue crew, operated continuously submerged for 48 days and 2 hours, then moored alongside the submarine tender, Proteus, in Holy Loch, Scotland. Following upkeep, the gold crew commenced its first patrol on Christmas Day, returning to Holy Loch in February 1963. The crews were again alternated, and Sam Houston departed on her third patrol in March. On this patrol, she was the first fleet ballistic missile submarine to enter the Mediterranean where she joined the NATO forces. On a short operational visit to Izmir Turkey, she became the first Polaris submarine to make a port-of-call during a patrol. With the two crews alternating every 90 days Sam Houston completed 6 successful Polaris patrols by the end of the year.
By the end of 1964, Sam Houston had completed 10 patrols. During 1965, she completed four additional deterrent patrols. During 1966, Sam Houston completed 3 more patrols, including her longest which lasted 71 days. On 10 August 1966, she returned to the United States for the first time since her deployment in 1962 and commenced a major overhaul at the United States Naval Shipyard at Portsmouth, N.H. On 30 October 1967, she got underway for sea trials, and, a month later, her blue crew began shakedown training. In January 1968, the gold crew conducted shakedown operations. Following further tests, she got under way for her 18th deterrent patrol, and put into Holy Loch on 25 May. By the end of the year, she was on her 21st patrol. During 1969, Sam Houston completed her 22nd through 24th patrols. In 1970, she continued to operate with Submarine Squadron 14 until shifting to the Mediterranean on 9 August to join Submarine Squadron 16.
She operated out of her advanced base at Rota, Spain, until October of 1972. On 27 November, she entered Charleston Naval Shipyard and began an extended in-port period, which included regular overhaul and the updating of her weapons and propulsion systems.
In 1981, in compliance with the SALT I treaty, Sam Houston's ballistic missile section was deactivated. Concrete blocks were placed in the missile tubes and the missile fire-control system was removed, as was one of her inertial navigation systems. Sam Houston was reclassified as an attack submarine with hull number SSN-609 on 10 November 1980 and retained primarily for training, antisubmarine warfare exercises, and other secondary duties.
From September 1982 to September 1985, Sam Houston, along with her sister ship USS John Marshall (SSBN-611), was modified at Puget Sound Naval Shipyard at Bremerton, Washington, as an amphibious transport to carry frogmen or commandos. This included the installation of additional troop berthing, the removal of some ballistic missile tube bases, and the conversion of other ballistic missile tubes into air locks and stowage for equipment. She was fitted with two dry deck shelters (DDSs) abaft her sail. These, which housed United States Navy SEAL team Swimmer Delivery Vehicles, allowed her to act as a SEAL mother ship.
On 29 April 1988, Sam Houston ran aground on Fox Island, Washington.
Deactivated on 1 March 1991 while still in commission, Sam Houston began the Nuclear Powered Ship and Submarine Recycling Program at Puget Sound Naval Shipyard the same day. She was formally decommissioned and stricken from the Naval Vessel Register on 6 September 1991 and finished the recycling program on 3 February 1992, when she was officially listed as scrapped.
