The Missouri (SSN 780) is the seventh Virginia-class submarine and the fifth ship in the United States Navy named in honor of the U.S. state of Missouri. The first USS Missouri was a steam/sail warship commissioned in 1842, only 21 years after Missouri was admitted into the union. In the midst of the Civil War, the Confederate Navy commissioned a paddle-wheel ironclad named CSS Missouri that served as a minelayer and troop transport.
