Construction and commissioning
The contract to build Pennsylvania was awarded to the Electric Boat Division of General Dynamics Corporation in Groton, Connecticut, on 29 November 1982 and her keel was laid down there on 10 January 1984. She was launched on 23 April 1988, sponsored by Mrs. Marilyn Garrett, and commissioned on 9 September 1989.
Service history
On 29 September 1989, Pennsylvania ran aground as she entered the channel during her first visit to Port Canaveral, Florida. Tugboats freed her in about two hours. A US Navy investigation determined that Pennsylvania was properly positioned in the channel, but the channel had been silted by the recent passing of Hurricane Hugo. Pennsylvania had been rerouted to Port Canaveral shortly after another submarine had struck a buoy that had repositioned in the entrance channel of Kings Bay. Still, it was thought that the channel to Port Canaveral had been unaffected. Pennsylvania received no damage. This was a rare occasion of a warship running aground and the commanding officer not being disciplined. Shortly after that, Pennsylvania departed on her first strategic deterrent patrol, which lasted 82 days.[6]
In 2001, Pennsylvania won the Marjorie Sterrett Battleship Fund Award for the United States Atlantic Fleet.
In 2009, Pennsylvania was featured in an episode of the British television documentary series Big, Bigger, Biggest.[7][unreliable source?]
In 2012, Pennsylvania completed a mid-life 2+1⁄2-year Engineered Refueling Overhaul (ERO) at Puget Sound Naval Shipyard, where her reactor was refueled for an estimated 25 more years of service.
On 14 June 2014, Pennsylvania completed a record-setting 140-day strategic deterrent patrol. This is the longest strategic deterrent patrol completed since the beginning of the Poseidon C3 missile program in the 1970s.[8]
On 2 October 2026, Pennsylvania arrived at its new homeport at Naval Submarine Base Kings Bay.[9]
