USS New Hampshire (SSN 778), the nation’s newest and most advanced nuclear-powered attack submarine, returned to the Electric Boat shipyard at Groton, Connecticut on 31 July following the successful completion of its first voyage in open seas, called alpha sea trials.
USS New Hampshire’s alpha sea trials included submerging for the first time, performing a range of submarine and propulsion-plant operations and conducting high-speed runs on the surface and underwater to demonstrate that the ship’s propulsion plant is fully mission-capable. USS New Hampshire will be delivered to the U.S. Navy by the end of summer.
“I’m privileged to have participated in the successful propulsion plant sea trial for a Virginia-class submarine,” said Director of Naval Nuclear Propulsion Adm. Kirkland Donald, who directed the sea trials.
“New Hampshire, the fifth of the Virginia Class, performed satisfactorily in all operations and this success is a direct result of the hard work of both the crew and the shipbuilders, Adm. Donald said. “The Navy and the nation need submarines like New Hampshire and I am confident that she will support the missions for which she was designed.”
The team reduced the time span between christening and sea trials from 11 months on the USS Virginia (SSN 774), the first ship of the Virginia Class nuclear attack submarines, to less than six weeks on the USS New Hampshire.
