USS Portsmouth (SSN-707), a Los Angeles-class submarine, was the fourth ship of the United States Navy to be named for Portsmouth, New Hampshire, and Portsmouth, Virginia. The contract to build her was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut on 10 December 1973 and her keel was laid down on 8 May 1980. She was launched on 18 September 1982 sponsored by Mrs. Helen Poe Goodrich, and commissioned on 1 October 1983, with Commander Donald M. Olson in command. The ceremony took place in Portsmouth, New Hampshire, her namesake city.
In 1984 Portsmouth entered her homeport of Groton, Connecticut, which she left for her permanent homeport at Ballast Point Submarine Base in San Diego. En route she transited through the Panama Canal and made a quick dash south for her first transit across the equator.
In 1985 Portsmouth commenced her first Western Pacific operations that included port-calls in Japan and Australia and became the first American nuclear-powered warship to visit Fiji. Years later she became the first to make a liberty call to communist Chinese reunified Hong Kong.
On 10 September 2004 Portsmouth decommissioned at Norfolk, Virginia and was scrapped at the shipyard in nearby Portsmouth, her other namesake city. While the submarine was only halfway through her design lifespan, her reactor core required refueling. Decommissioning was chosen as a cost-saving measure.
The ship deployed to 7th Fleet in 1997. The crew was awarded the Navy Expeditionary Medal. Upon return to homeport, the ship was again awarded the COMSUBRON 11 Battle "E", judged the most battle effective submarine in her squadron.
