June 2, 2012 The world's most advanced fast attack nuclear submarine, USS Mississippi was officially Commissioned to the United States Navy. United States Secretary of the Navy, Ray Mabus, a native of Mississippi, was Principle Speaker for the event. Taking place in Pascagoula, Mississippi, Mabus officially Commissioned the sub to the Navy. After setting the first watch, the crew was ordered to "Man the ship and bring her to Life!" The Virginia class sub is billed as the Navy’s “next generation” of attack subs. The Mississippi's naming recognizes the state's tradition of shipbuilding and honors the spirit of the people of Mississippi who have made great strides in recovering from the devastation of Hurricane Katrina. Construction on the USS Mississippi began in February 2007. The submarine is 377 feet long and 34 feet in diameter. SSN 782 is the fifth US Navy vessel to be named the USS Mississippi.
