SSN-790 South Dakota

SSN-790 The newest Virginia-class attack submarine, USS South Dakota (SSN 790), was commissioned at Groton, Connecticut, Feb. 2, 2019. It is the 17th Virginia-class attack submarine to join the fleet.

The Navy christened a new attack submarine, the future USS South Dakota (SSN 790), during a 10 a.m. EDT ceremony Saturday, Oct. 14, at General Dynamics Electric Boat Shipyard in Groton, Connecticut. Governor of South Dakota Dennis Daugaard delivered the ceremony's principal address. The submarine's sponsor is Mrs. Deanie Dempsey, wife of the 18th Chairman of the Joint Chiefs of Staff, Gen. Martin Dempsey. The ceremony was highlighted by Mrs. Dempsey breaking a bottle of sparkling wine across the bow to formally christen the ship, a time-honored Navy tradition.

"Today's christening of South Dakota brings this submarine one step closer to joining our strong fleet," said Secretary of the Navy Richard V. Spencer. "For decades to come, this boat and the Sailors who will serve on it will stand as a tribute to the patriotic people of South Dakota and a testament to the value of the partnership between the Department of the Navy and our industry teammates."

Secretary of the Navy Ray Mabus hosted a ship naming ceremony in honor of USS South Dakota, 23 June 2012, at 2 p.m. CDT at the USS South Dakota Battleship Memorial in Sioux Falls, S.D. South Dakota, a Virginia-class submarine designated SSN 790, is the third ship to bear the state's name. The second ship was a battleship that stood as the lead ship of her class and earned 13 battle stars during her extensive service in the Pacific theater during World War II.

The U.S. Navy accepted delivery of the future USS South Dakota (SSN 790), the 17th submarine of the Virginia class, Sept. 24. The ship began construction in 2013 and is scheduled to commission in early 2019. This next-generation attack submarine provides the Navy with the capabilities required to maintain the nation's undersea superiority.

"South Dakota's delivery is an important milestone," said Capt. Chris Hanson, Virginia Class Program manager. "It marks the penultimate Block III delivery and will be a vital asset in the hands of the fleet." The submarine's sponsor is Deanie Dempsey, wife of former Joint Chiefs of Staff chairman and retired Army Gen. Martin Dempsey.

South Dakota is the 17th Virginia-class attack submarine and the seventh Virginia-class Block III submarine. The ship began construction in 2013 and is contracted to deliver in August 2018. South Dakota will provide the Navy with the capabilities required to maintain the nation's undersea superiority well into the 21st century.

Block III Virginia-class submarines feature a redesigned bow, which replaces 12 individual launch tubes with two large-diameter Virginia Payload Tubes, each capable of launching six Tomahawk cruise missiles.

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.

The submarine will be the third U.S. Navy ship to be commissioned with the name South Dakota. The first South Dakota (ACR 9) was a Pennsylvania-class armored cruiser. The ship served in the Pacific until the American entry into World War I, where it patrolled the South Atlantic operating from Brazil, and escorted troop transports destined for Europe.

During World War II, the second South Dakota (BB 57) was commissioned as the lead ship in its class. The four ships of the South Dakota class are considered the most efficient battleships built under the limitations of the Washington Naval treaty. South Dakota served in the Pacific and Atlantic as a carrier escort and patrolled the North Atlantic with the British navy. During the ship's second tour in the Pacific, it helped to cripple the Japanese navy during the Battle of the Philippine Sea before helping to bombard shore defenses at Okinawa and preparing for an eventual invasion of the Japanese home islands.
