USS Delaware (SSN-791), which successfully completed sea trials earlier this month, is the ninth Virginia-class submarine to be delivered by Newport News and the 18th built as part of the teaming agreement with General Dynamics Electric Boat.

«Like the last two submarines we delivered to the Navy, Delaware has received some of the highest quality scores since the Virginia-class program began», said Dave Bolcar, Newport News’ vice president of submarine construction. «Our team of shipbuilders continues to perform at a high level, and nothing makes us prouder than delivering one of the most mission-ready submarines to the fleet».

The submarine is the second ship to be named for the country’s first state, the first being the dreadnought battleship USS Delaware (BB-28), which was delivered by Newport News in 1910.

More than 10,000 shipbuilders from Newport News and Electric Boat have participated in Delaware’s construction since the work began in September 2013. The submarine was christened by Jill Biden, the former Second Lady of the United States and the ship’s sponsor, during a ceremony in October 2018.

The future USS Delaware (SSN-791) will be commissioned next year.

Initial Sea Trials

Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division successfully completed the initial sea trials on the newest Virginia-class submarine, USS Delaware (SSN-791).

The submarine, in the final stages of construction, spent three days at sea proving all of its systems, components and compartments. Delaware submerged for the first time and performed high-speed maneuvers on the surface and underwater.

«Delaware performed well during sea trials, which is a testament to the skill and craftsmanship of the incredible team of shipbuilders who are working to uphold our high standards of quality», said Dave Bolcar, Newport News’ vice president of submarine construction. «We look forward to continuing our testing program to deliver the submarine to the U.S. Navy later this year».

The submarine is scheduled to undergo a round of acceptance trials before it is delivered. More than 10,000 shipbuilders from Newport News and teaming partner General Dynamics Electric Boat and thousands of companies across 48 states have participated in Delaware’s construction since the work began in September 2013.

Huntington Ingalls Industries is America’s largest military shipbuilding company and a provider of professional services to partners in government and industry. For more than a century, HII’s Newport News and Ingalls shipbuilding divisions in Virginia and Mississippi have built more ships in more ship classes than any other U.S. naval shipbuilder. HII’s Technical Solutions division provides a wide range of professional services through its Fleet Support, Mission Driven Innovative Solutions, Nuclear & Environmental, and Oil & Gas groups. Headquartered in Newport News, Virginia, HII employs more than 41,000 people operating both domestically and internationally.

Dakota Commissioned

The Navy commissioned its newest fast attack submarine, the USS South Dakota (SSN-790), during an 11 a.m. (EST) ceremony Saturday, February 2, at Naval Submarine Base New London in Groton, Connecticut.

The principal speaker was U.S. Senator Mike Rounds of South Dakota. The submarine’s sponsor is Mrs. Deanie Dempsey, wife of the 18th Chairman of the Joint Chiefs of Staff, General Martin Dempsey. She gave the order to «man our ship and bring her to life!» in a time-honored Navy tradition.

«USS South Dakota enters service during a period of dynamic security challenges», said Secretary of the Navy Richard V. Spencer. «I am confident USS South Dakota and its crew will ensure our Navy and nation remain safe and strong, and proudly serve our nation’s interest for decades to come».

USS South Dakota, a Virginia-class submarine designated SSN-790, is the third ship to bear the state’s name. The first South Dakota was an armored cruiser commissioned January 27, 1908. The ship served in a convoy escort role during World War I before being renamed Huron June 7, 1920. She was decommissioned following seven years of service in the Pacific June 17, 1927. The second ship was a battleship commissioned March 20, 1942. She saw service in a number of important World War II battles including Santa Cruz, Guadalcanal, Philippine Sea, and Okinawa, earning thirteen battle stars over the course of the war. South Dakota was present at Tokyo Bay when the Japanese surrendered and was later placed out of commission January 31, 1947.

USS South Dakota (SSN-790) is the 17th Virginia-class attack submarine and the seventh Virginia-class Block III submarine. Virginia-class submarines are built to operate in the world’s littoral and deep waters while conducting anti-submarine warfare; anti-surface ship warfare; strike warfare; special operation forces support; intelligence, surveillance, and reconnaissance; irregular warfare; and mine warfare missions. Their inherent stealth, endurance, mobility, and firepower directly enable them to support five of the six maritime strategy core capabilities – sea control, power projection, forward presence, maritime security, and deterrence.
