First Virginia class Block III nuclear-powered attack submarine North Dakota completes first voyage
 
The U.S. Navy's newest and most advanced nuclear-powered attack submarine, North Dakota (SSN-784), returned to the General Dynamics Electric Boat shipyard Tuesday following the successful completion of its first voyage in open seas, called alpha sea trials. North Dakota is the 11th ship of the Virginia Class, the most capable class of attack submarines ever built. Electric Boat is a wholly owned subsidiary of General Dynamics.

North Dakota’s alpha sea trials included a range of submarine and propulsion-plant operations, submerging for the first time, and high-speed runs on and below the surface to demonstrate that the ship's propulsion plant is fully mission-capable.

The sea trials were directed by U.S. Navy Adm. John M. Richardson, director – Naval Nuclear Propulsion. Also participating in the sea trials were Vice Adm. William H. Hilarides, commander – Naval Sea Systems Command; Rear Adm. David C. Johnson, program executive officer – Submarines; Rear Adm. Kenneth Perry, commander – Submarine Group Two; Capt. Darlene Grasdock, supervisor of shipbuilding in Groton; and Jeffrey S. Geiger, president of Electric Boat. North Dakota is commanded by Capt. Douglas Gordon.

"The crew and shipbuilders worked together as one unit to take this submarine to sea and put it through its paces," said Electric Boat President Jeffrey Geiger. "It was an outstanding effort by everyone involved, and demonstrates the commitment of the Navy and industry team to sustain the success of the Virginia-class submarine program. I appreciate the contributions made by the Navy personnel, shipbuilders and suppliers who made it happen."

Electric Boat and its construction teammate, Newport News Shipbuilding, already have delivered 10 Virginia-class submarines to the Navy: USS Virginia (SSN-774), USS Texas (SSN-775), USS Hawaii (SSN-776), USS North Carolina (SSN-777), USS New Hampshire (SSN-778), USS New Mexico (SSN-779), USS Missouri (SSN-780), USS California (SSN-781), USS Mississippi (SSN-782) and USS Minnesota (SSN-783). Eight other submarines of the class are under construction.

In May, the U.S. Navy underscored its commitment to an advanced and adaptable submarine force by awarding Electric Boat a contract valued at $17.6 billion for the construction of 10 additional Virginia-class submarines.

Virginia-class submarines displace 7,800 tons, with a hull length of 377 fee t and a diameter of 34 feet. They are capable of speeds in excess of 25 knots and can dive to a depth greater than 800 feet, while carrying Mark 48 advanced capability torpedoes and Tomahawk land-attack missiles.

When commissioned Oct. 25, the USS North Dakota will be the first of the Block III Virginia class SSNs which features a revised bow, technologies from Ohio-class SSBNs and the Virginia Payload Module.
