USS Missouri (SSN-780) is a Virginia-class attack submarine of the United States Navy, notable for being the seventh vessel in this class and the fourth to bear the name honoring the state of Missouri. Displacing approximately 7,800 tons, Missouri was constructed with a joint effort between General Dynamics Electric Boat and Northrop Grumman Shipbuilding-Newport News, with final assembly taking place in Groton, Connecticut. The keel of USS Missouri was laid on 27 September 2008, marking the beginning of her construction. The submarine was launched into the water on 20 November 2009 and subsequently christened on 5 December 2009, with Becky Gates, wife of Secretary of Defense Robert Gates, serving as her sponsor. She was officially commissioned into the fleet on 31 July 2010 and is assigned to Submarine Squadron 4 based at the U.S. Naval Submarine Base in New London, Connecticut. Missouri’s design and construction involved collaboration between two major shipyards, with sections built at both Groton and Newport News. Her assembly was completed at Groton, and she features the advanced capabilities typical of Virginia-class submarines, including stealth, agility, and a versatile armament suite suited for a variety of missions. Her operational history includes a significant first deployment—a six-month patrol to the U.S. 6th Fleet area of operations, completed on 20 December 2013. In 2014, she conducted an 11-week surge deployment in the Northern Atlantic, likely influenced by regional geopolitical tensions such as the annexation of Crimea by Russia. The submarine continued active service with the 6th Fleet through 2015. On 26 January 2018, USS Missouri transitioned to her new homeport in Pearl Harbor, Hawaii, and she returned there on 31 March 2022 after a deployment to the 7th Fleet. Through her service, USS Missouri exemplifies the technological advancement and strategic importance of modern U.S. naval submarines.
