Keel-laying ceremony

General Dynamics Electric Boat (GDEB) held a keel-laying ceremony for future USS Iowa (SSN-797), the 24th unit in the U.S. Navy’s Virginia-class of nuclear-powered attack submarines. The ceremony took place at General Dynamics Electric Boat Quonset Point facility on August 20, 2019.

Virginia-class attack submarine

The keel laying of a ship is a time-honored tradition. In the days of wooden ships, the start of construction was marked by the laying of the first timber – the backbone of the vessel. Today, this celebration is modified to reflect current manufacturing methods as well as the cylindrical shape of modern submarines. Shipbuilders and sailors refer to the bottom centerline of the submarine as the keel.

The newest USS Iowa (SSN-797) is being built under a teaming agreement between General Dynamics Electric Boat (GDEB) and Huntington Ingalls Industries’ Newport News Shipbuilding division wherein both companies build certain portions of each submarine and then alternate deliveries. Iowa is also the fourth U.S. Navy ship to bear the name. The last ship to bear the name was the lead ship of Iowa-class battleships which saw action in World War II, the Korean and Vietnam Wars and the Gulf War.

USS Iowa (SSN-797) belongs to the Block IV submarines which incorporate improvements that allow them to spend less time undergoing maintenance. They are scheduled to undergo three major maintenance overhauls during their lifetime, compared to their predecessors’ four, enabling them to perform an additional deployment. The submarines are built under a $17.8 billion contract awarded in April 2014 with General Dynamic Electric Boat as the prime contractor.

There are currently eight Virginia-class submarines in various stages of construction at Quonset Point and one Columbia-class hull. Over the next few years, the site will grow considerably, adding an additional 13-acres of hull outfitting space for Virginia and Columbia class submarines.

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.

The principal speaker was Vermont Governor Phil Scott. Ms. Gloria Valdez, former Deputy Assistant Secretary of the U.S. Navy (Ships), served as the ship’s sponsor. In a time-honored Navy tradition, she christened the ship by breaking a bottle of sparkling wine across the bow and state, «In the name of the United States, I christen thee».

«The future USS Vermont (SSN-792) honors the contributions and support that the state of Vermont has given to our Navy and Marine Corps team throughout the years», said Secretary of the U.S. 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 Vermont and a testament to the value of the partnership between the Department of the U.S. Navy and our industry teammates».

The future USS Vermont, designated SSN-792, is the third U.S. Navy ship to bear the name of the «Green Mountain State». The first Vermont was one of nine 74-gun warships authorized by Congress in 1816. The ship spent her early life laid up, but was put into service as a store and receiving ship during the Civil War. She continued in that service until struck from the Navy list in 1901. The second Vermont (Battleship No. 20) was laid down in May 1904 and commissioned March 4, 1907. She was a member of The Great White Fleet that conducted a world cruise during the Presidency of Theodore Roosevelt. Later she participated in the American occupation of Vera Cruz, Mexico. During World War I, she served as an engineering training ship before being converted to carry out her final missions as a troop transport, returning about 5,000 World War I U.S. service members from Europe. She was decommissioned June 30, 1920.

The future USS Vermont (SSN-792) is the 19th Virginia-class attack submarine and the first of ten Virginia-class Block IV submarines. The ship’s construction began in May 2014 and it will deliver in the fall of 2019. USS Vermont (SSN-792) will provide the U.S. Navy with the capabilities required to maintain the nation’s undersea superiority well into the 21st century.

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 ship began construction in 2013 and is scheduled to commission in early 2019. This next-generation attack submarine provides the U.S. Navy with the capabilities required to maintain the nation’s undersea superiority.

USS South Dakota (SSN-790) is the seventh Virginia-class Block III submarine. Block III submarines feature a redesigned bow with enhanced payload capabilities, replacing 12 individual vertical launch tubes with two large-diameter Virginia Payload Tubes, each capable of launching six Tomahawk cruise missiles. This, among other design changes, reduced the submarines’ acquisition cost while maintaining their outstanding warfighting capabilities.

«South Dakota’s delivery is an important milestone», said Captain 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 General Martin Dempsey.

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.

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 operations 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 future USS Indiana (SSN-789) is the 16th Virginia-class submarine built as part of the teaming agreement with General Dynamics Electric Boat and the eighth delivered by Newport News.

«We are proud to deliver Indiana to the Navy», said Dave Bolcar, Newport News’ vice president of submarine construction. «For the nearly 4,000 shipbuilders who participated in construction of the boat, there is nothing more important than knowing that this vessel will support the Navy’s missions».

Indiana, which began construction in September 2012, successfully completed sea trials earlier this month. The vessel will be commissioned later this year.

Virginia-class submarines are built for a broad spectrum of open-ocean and littoral missions to replace the Navy’s Los Angeles-class submarines as they are retired. Virginia-class submarines incorporate dozens of new technologies and innovations that increase firepower, maneuverability and stealth and significantly enhance their warfighting capabilities. These submarines are capable of supporting multiple mission areas and can operate at submerged speeds of more than 25 knots/28 mph/46.3 km/h for months at a time.

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, Integrated Missions Solutions, Nuclear & Environmental, and Oil & Gas groups. Headquartered in Newport News, Virginia, HII employs nearly 39,000 people operating both domestically and internationally.

Under the contract with General Dynamics Electric Boat, a builder of the Virginia class, BAE Systems will deliver two sets, each consisting of four tubes, for the Virginia Payload Modules on the SSN-804 and SSN-805.

The Virginia Payload Module (VPM) extends the length of the Block V submarines over previous versions of the Virginia-class by adding an additional mid-body section to create more payload space for greater firepower. Each large-diameter payload tube can store and launch up to seven Tomahawk cruise missiles. The VPM offers exceptional flexibility as well for the integration of future payload types, such as unmanned systems or next-generation weapons.

«The Virginia Payload Module is critical to the Navy’s undersea presence», said Joe Senftle, vice president and general manager of Weapon Systems at BAE Systems. «With the VPM, the Navy is adding significant capability to the Virginia-class by increasing the firepower of these subs and tripling their payload capacity».

BAE Systems, which is also providing payload tubes for the SSN-803 under a previously awarded VPM contract, has a long history of supporting the Navy’s submarine fleet as the leading provider of propulsors and other submarine systems. The company was selected to provide propulsors, spare hardware, and tailcones for Block IV Virginia-class vessels and stands ready to provide the same support for the Block V subs.

Under this most recent contract, BAE Systems will also develop the processes and tooling necessary for the Block V payload tube production. Work will be performed at the company’s facility in Louisville, Kentucky, with deliveries scheduled to begin in 2020.

Keel laying ceremony

The U.S. Navy held a keel laying ceremony for the Virginia-class submarine Pre-Commissioning Unit Hyman G. Rickover (SSN-795) at General Dynamics Electric Boat, May 11.

U.S. Navy & GDEB Laid Keel of Future USS Hyman G. Rickover (SSN-795)

The initials of the submarine’s sponsor, Darleen Greenert, were welded onto a steel plate that will be permanently affixed to the submarine. She is the wife of former Chief of Naval Operations Admiral Jonathan Greenert (retired).

Admiral Frank Caldwell, Jr., director of the Naval Nuclear Propulsion Program, stated, «Admiral Rickover’s gift to our Nation’s defense – safe, reliable, and militarily superior naval nuclear propulsion – is as vital to our warfighting edge today as it was at the beginning of the Naval Nuclear Propulsion Program 70 years ago. The U.S. Navy and our nation are proud to honor his achievements and legacy with this submarine».

The submarine began construction on September 30, 2015 and is on track to continue the Virginia-class program’s trend of delivering quality submarines within budget and ready for tasking by the fleet.

This will be the second submarine to be named after Admiral Hyman G. Rickover to honor the pioneer of the nuclear navy. The first submarine named for the admiral was the Los Angeles-Class submarine USS Hyman G. Rickover (SSN-709), which served from 1984 to 2006.

Admiral Rickover served for 63 years on active duty service, making him the longest serving member of the U.S. armed forces in history. In the late 1940’s, Admiral Rickover was made director of the Naval Reactors Branch of the Bureau of Ships and he subsequently led the efforts to develop what would become the USS Nautilus, the world’s first nuclear-powered submarine. Admiral Rickover also established and enforced strict safety standards, leading to the U.S. Navy’s safety record of over 162,000,000 miles safely steamed on nuclear power.

Other Virginia-class milestones this year include the commissioning of the USS Indiana (SSN-789) and the combined keel laying and christening of USS Vermont (SSN-792), both currently projected to occur in the fall.

This next-generation attack submarine provides the U.S. Navy with the capabilities required to maintain the nation’s undersea superiority well into the 21st century.

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; 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 principal speaker was U.S. Senator Cory Gardner of Colorado. Annie Mabus, daughter of 75th Secretary of the Navy Ray Mabus, served as the ship’s sponsor. In a time-honored Navy tradition, she gave the order to «man our ship and bring her to life»!

«USS Colorado is a true marvel of technology and innovation, and it shows the capability that our industrial partners bring to the fight», said Secretary of the U.S. Navy Richard V. Spencer. «Today’s world requires undersea platforms designed for dominance across a broad spectrum of regional and littoral missions, and I am confident Colorado will proudly serve in defense of our nation’s interests for decades to come».

The future Colorado, which began construction in 2012, is the 15th Virginia-class fast attack submarine and the fifth Virginia-class Block III submarine. Colorado will be the fourth U.S. Navy ship to be commissioned with a name honoring the state of Colorado. The first Colorado was a three-masted steam screw frigate that participated in the Union Navy’s Gulf Blockading Squadron and fought in the Second Battle of Fort Fisher with then-Lt. George Dewey serving as her executive officer. In the early years of the 20th century, the second Colorado (ACR-7) was a Pennsylvania-class armored cruiser that escorted convoys of men and supplies to England during World War I. The third ship of her name, the lead ship of the Colorado class of battleships (BB-45), supported operations in the Pacific theater throughout World War II, surviving two kamikaze attacks and earning seven battle stars.

This next-generation attack submarine provides the U.S. 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.

Christening of Dakota

The U.S. Navy christened its newest attack submarine, the future USS South Dakota (SSN-790), during a 10 a.m. EDT ceremony Saturday, October 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, General 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 U.S. 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».

USS 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.

USS South Dakota (SSN-790) 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. USS South Dakota (SSN-790) will provide the U.S. 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 (VPTs), 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.
