North Dakota Submarine Completes Alpha Sea Trials
The US nation’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.
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 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.
