USS North Carolina (SSN-777), a Virginia-classattack submarine, is the fourth vessel of the United States Navy named for U.S. state of
North Carolina. The contract to build her was awarded to Northrop Grumman Newport News on 30 September 1998 and her keel was laid down on 24 May 2004. She was launched on 5 May 2007. North Carolina was commissioned on 3 May 2008 in Wilmington, North Carolina.
This class of submarine is unique in that it features the Photonics Mast Program (PMP) that freed ship designers to place the boat's control room in a lower, less geometrically constrained space than would be required by a standard, optical tube periscope. It is additionally unique in the U.S. Navy for featuring all-digital ship and ballast control systems that are operated by relatively senior watchstanders and a pressure chamber to deploy SEAL divers while being submerged.[citation needed] She is capable of diverse missions, including conventional submarine warfare, strike warfare, mining operations, and delivery of special operations personnel and equipment.[4]
North Carolina joined the fleet on 21 February 2008, after problems with the boat's steam valve and internal piping system had forced two delays in the acceptance of the vessel.[6] Welding issues in the internal piping system scuttled a first-planned December 2007 delivery, and the discovery of an inadequate steam valve forced a further delay from January to February 2008.
In 2010, North Carolina changed homeports from Naval Submarine Base New London to Naval Station Pearl Harbor.[9] She left Groton for Pearl Harbor on 22 July 2010 and arrived at her new homeport, Joint Base Pearl Harbor–Hickam, on Monday, 15 November 2010 after her four-month transfer activities. During the transfer, the officers and crew of North Carolina conducted a series of exercises designed to test the boat's new combat systems and stealth capabilities. North Carolina is the third Virginia-class attack submarine to be homeported at Joint Base Pearl Harbor–Hickam and is assigned to Commander, Submarine Squadron 1.[10]
