USS Missouri (SSN-780) is the seventh Virginia-class attack submarine and the fourth ship in the United States Navy named in honor of the U.S. state of Missouri. She was completed, and delivered, nine months early and under budget.

The 7,800-ton submarine Missouri was built under a joint arrangement between General Dynamics Electric Boat and Northrop Grumman Shipbuilding-Newport News. Sections of the submarine were built at both shipyards with final assembly completed at one or the other.

The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered cruise missile fast-attack submarines, in service in the United States Navy.

They are designed to excel in anti-submarine warfare, anti-ship warfare, strike warfare, special operations, intelligence, surveillance and reconnaissance, irregular warfare, and mine warfare. Fast-attack submarines project power ashore with special operations forces and Tomahawk cruise missiles in the prevention or preparation of regional crises.

The Virginia-class submarine has a length of 114.8 m, and a beam of 10.36 m. The submarine can reach a top speed of 28 miles per hour (45 km/h). She has a crew of 132 people including 15 officers and 117 enlisted.

The Virginia Class is equipped with twelve Vertical Launch System (VLS) tubes and four torpedo tubes (starting with SSN 784 North Dakota [Block II], the 12 VLS tubes are replaced by 2 large-diameter payload tubes).

The submarines also carry Mk 48 ADCAP Torpedoes, UGM-109 Tomahawk cruise missiles, Mk 60 CAPTOR mines, advanced mobile mines, and unmanned underwater vehicles.
