The USS George Bancroft (SSBN-643) was a Benjamin Franklin class (also known as the "640-class") fleet ballistic missile submarine constructed for the United States Navy. As the fourth vessel to bear the name in honor of George Bancroft, a prominent 19th-century Secretary of the Navy and founder of the U.S. Naval Academy, this submarine played a vital role in Cold War strategic deterrence. Construction of the George Bancroft began with the awarding of the contract to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on November 1, 1962. Her keel was laid down on August 24, 1963, and she was launched on March 20, 1965. The launch was sponsored by Mrs. Jean B. Langdon and Mrs. Anita C. Irvine, descendants of George Bancroft. Following fitting out, the vessel was commissioned on January 22, 1966, under the command of Captain Joseph Williams of the Blue Crew, with a Gold Crew also assigned for alternate operations. The USS George Bancroft was assigned to Submarine Squadron 14 within Submarine Flotilla 6, based out of New London, Connecticut. Her primary mission was strategic deterrence through ballistic missile patrols. Her first deterrent patrol commenced on July 26, 1966, from New London, with her Blue Crew. After successfully completing this patrol and arriving in Holy Loch, Scotland, the Blue Crew was relieved by the Gold Crew. The submarine conducted subsequent patrols in 1966 and early 1967, alternating crews to maintain a continuous deterrent presence. The vessel was decommissioned on September 21, 1993, and stricken from the Naval Vessel Register the same day. Her scrapping was completed by March 30, 1998, at Bremerton, Washington, through the Nuclear-Powered Ship and Submarine Recycling Program. Today, her sail is preserved and on display at Naval Submarine Base Kings Bay, Georgia, serving as a memorial to her service and the strategic deterrent role she played during her operational lifetime.
