Sub completes sea trial

GROTON, Conn. -- The nation's newest nuclear-powered attack submarine, Mississippi (SSN-782), returned to the Electric Boat shipyard following the successful completion of its first voyage in open seas. During the alpha sea trials, Mississippi submerged for the first time and conducted high-speed runs on and under the surface to demonstrate that the submarine's propulsion plant is fully mission-capable. Mississippi is the ninth ship of the Virginia Class. The submarine will be commissioned June 2 in Pascagoula, Miss. Electric Boat is a wholly owned subsidiary of General Dynamics.
