USS Pennsylvania (SSBN-735) is a nuclear-powered, United States Navy Ohio-class ballistic missile submarine that has been in commission since 1989. She is the fourth ship of the United States Navy to be named for the Commonwealth of Pennsylvania.
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.
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 2009, Pennsylvania was featured in an episode of the British television documentary series Big, Bigger, Biggest . [7]
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]
The Ohio class of nuclear-powered submarines includes the United States Navy's 14 ballistic missile submarines (SSBNs) and its four cruise missile submarines (SSGNs). Each displacing 18,750 tons submerged, the Ohio-class boats are the largest submarines ever built for the U.S. Navy. They are the world's third-largest submarines, behind the Russian Navy's Soviet-designed 48,000-ton Typhoon class and 24,000-ton Borei class. At 20 Trident II missiles apiece, Ohio-class boats carry just as many missiles, if not more, than either the Borei class or the deactivated Typhoon class (20).
USS Patrick Henry (SSBN-599), named after the American Revolutionary War figure and Founding Father Patrick Henry (1736–1799), was a George Washington class nuclear-powered fleet ballistic missile submarine of the United States Navy. She was later converted into an attack submarine and redesignated SSN-599.
USS Ohio (SSBN-726/SSGN-726), the lead boat of her class of nuclear-powered fleet ballistic missile submarines (SSBN), is the fourth vessel of the United States Navy to be named for the U.S. state of Ohio. She was commissioned with the hull designation of SSBN-726, and with her conversion to a guided missile submarine she was re-designated SSGN-726.
The George Washington class was a class of nuclear-powered ballistic missile submarines deployed by the United States Navy. George Washington, along with the later Ethan Allen, Lafayette, James Madison, and Benjamin Franklin classes, comprised the "41 for Freedom" group of submarines that represented the Navy's main contribution to the nuclear deterrent force through the late 1980s.
USS Michigan (SSBN-727/SSGN-727) is an Ohio-class nuclear-powered guided missile submarine (SSGN), converted from a ballistic missile submarine (SSBN), that is part of the United States Navy. She is the third vessel to bear the name of the U.S. state of Michigan.
USS Theodore Roosevelt (SSBN-600), a George Washington-class submarine, was the second ship of the United States Navy to be named for President Theodore Roosevelt (1858–1919). Initially unnamed and assigned hull classification symbol SSGN-600 as a guided missile submarine, her keel was laid down on 20 May 1958 by the Mare Island Naval Shipyard using components initially assembled for the Skipjack-class submarine nuclear attack submarine USS Scamp (SSN-588). She was named Theodore Roosevelt and redesignated fleet ballistic missile submarine SSBN-600 on 6 November 1958, launched on 3 October 1959, sponsored by Alice Roosevelt Longworth, daughter of Theodore Roosevelt and widow of Nicholas Longworth III, and commissioned on 13 February 1961 with Commander William E. Sims commanding the Blue Crew and Commander Oliver H. Perry, Jr. commanding the Gold Crew.
USS Abraham Lincoln (SSBN-602), a George Washington-class fleet ballistic missile submarine, was the second ship of the United States Navy to be named for Abraham Lincoln, the 16th President of the United States (1861–1865), the first being USS President Lincoln.
USS Sam Houston (SSBN-609/SSN-609), an Ethan Allen-class submarine, was the second ship of the United States Navy to be named after Sam Houston (1793–1863), president of the Republic of Texas. Sam Houston was the US Navy's seventh ballistic missile submarine.

Maryland is the fourth US Navy vessel to be named after the US state of Maryland. Her mission is to provide the United States government with an undetectable and unattackable nuclear launch platform in support of the national strategy of strategic deterrence. The contract for the construction of the Maryland was awarded on 14 March 1986. Her keel was laid down by the Electric Boat Division of the General Dynamics Corporation at Groton, Connecticut, on 22 April 1986.
