Navy lays the keel

On 24th August 2020, the U.S. Navy held a keel-laying ceremony in Groton, Connecticut and officially began the construction of a new Virginia-class attack submarine USS Idaho (SSN-799).

Sponsor Teresa Stackley laid the keel of the USS Idaho (SSN-799) on August 24, 2020 at the Quonset Point Facility of General Dynamics Electric Boat in North Kingston, Rhode Island

The U.S. Navy held a ceremony with former Idaho Governor Dirk Kempthorne Monday to name Nicholas Meyers as the USS Idaho (SSN-799) commander. Its crew of 135 sailors will also feature three native Idahoans.

General Dynamics Electric Boat Division is constructing this $2.44 billion piece of equipment at a shipyard in Quonset Point, Rhode Island. The submarine is 377 feet/114.8 m long, can travel up to 25 knots/28 mph/46.3 km/h and is capable of diving 800 feet/244 m.

The future USS Idaho (SSN-799) will be the fifth U.S. naval vessel named after the Gem State. The USS Idaho (SSN-799) will be the 26th submarine of the Virginia-class which is the most advanced nuclear submarine of the U.S. Navy.

The USS Idaho (SSN-799) will be the fifth ship to represent Idaho, but the first in more than a century. The last one was a battleship that played a crucial role in the Battle of Iwo Jima during World War II.

Next Phase

General Dynamics Electric Boat announced on June 12, 2020 that it had signed a contract to begin the next phase of construction on a facility to support construction of the nation’s new class of ballistic-missile submarines. The company signed a $544 million contract with AECOM of Los Angeles, California, to complete the construction of the South Yard Assembly Building (SYAB), the centerpiece of the biggest facility expansion in 50 years at the company’s Groton shipyard.

This photo shows recently-completed drilled shafts with pile caps that will support the deck of a 200,000 square-foot/18,580 square-meter building dedicated to the construction of the Columbia class of ballistic missile submarines, expected to be complete in 2023

In September 2019 the company broke ground on the SYAB, a 200,000 square-foot/18,580 square-meter building that will eventually be home to 1,400 skilled shipbuilders who will deliver the Columbia class to the U.S. Navy. Electric Boat is also expanding and modernizing other manufacturing spaces in Groton and building a floating dry dock.

Electric Boat is the prime contractor on the design and build of the 12 ships of the Columbia class, which will replace the aging Ohio-class of ballistic-missile submarines. Early construction began in 2017 at the company’s facility in Quonset Point, Rhode Island. Final assembly and test of the Columbia class will take place starting in 2024 at Electric Boat’s shipyard in Groton.

«General Dynamics Electric Boat continues to make investments – in facilities, in our supply chain and in the next generation of shipbuilders – to support the Columbia class, the Navy’s top strategic priority», said EB President Kevin Graney. «Efficient completion of the SYAB will position us to begin delivering the next-generation of ballistic submarines in advance of the Ohio-class retiring from service».

The South Yard Assembly Building is part of an overall $1.7 billion investment the company is making in modernizing and upgrading its facilities to meet the expanded needs of the U.S. Navy.

The company has hired and trained thousands of new employees and has worked with its national network of suppliers to prepare for the estimated 150% increase in the need for supplies and materials to concurrently build the Columbia and Virginia classes.

Vermont

The U.S. Navy commissioned USS Vermont (SSN-792), the 19th Virginia-class attack submarine, today, April 18, 2020.

USS Vermont (SSN-792) becomes latest Virginia-class fast-attack submarine in service

Although the traditional public commissioning ceremony was cancelled due to public health safety and restrictions of large public gatherings, the U.S. Navy commissioned USS Vermont (SSN-792) administratively and transitioned the ship to normal operations. Meanwhile, the Navy is looking at a future opportunity to commemorate the special event with the ship’s sponsor, crew and commissioning committee.

«This Virginia-class fast-attack submarine will continue the proud naval legacy of the state of Vermont and the ships that have borne her name», said Acting Secretary of the Navy James E. McPherson. «I am confident the crew of this cutting edge platform will carry on this tradition and confront the challenges of today’s complex world with the professionalism and dedication our nation depends on from warriors of the silent service».

Vice Admiral Daryl Caudle, commander, Submarine Forces, said Vermont’s entry to service marks a new phase of American undersea warfare dominance for a global Submarine Force that is ready to deter, defend and defeat threats to our nation, allies, and rules-based international order.

«This warship carries on a proud Vermont legacy in naval warfare and unyielding determination stretching back to the birth of our nation», Caudle said. «To her crew, congratulations on completing the arduous readiness training to enter sea trials and prepare this ship for battle. I am proud to serve with each of you! Stand ready to defend our nation wherever we are threatened – honoring your motto – FREEDOM AND UNITY. May God bless our Submarine Force, the people of Vermont, and our families! From the depths, we strike»!

The ship’s sponsor, Ms. Gloria Valdez, former deputy assistant secretary of the U.S. Navy (Ships), offered her gratitude to everyone who played a role in delivering USS Vermont (SSN-792) to service. She said she is proud to represent the crew and the first Block IV Virginia-class submarine to enter service.

«I am very proud of the sailors and families of USS Vermont (SSN-792) who worked so hard to bring her to life, and also feel extremely grateful to everyone who played a role preparing her to defend our nation for generations to come», Valdez said. «I look forward to commemorating this special occasion together with the crew in the future».

Vermont’s commanding officer, Commander Charles W. Phillips III, highlighted Vermont’s accomplishments over the past several weeks getting through initial sea trials. The hard work and dedication of the entire team during the past few years was evident in the successful execution of at-sea testing. He said he is especially thankful to the crew and their families, ship sponsor Ms. Valdez, and the USS Vermont (SSN-792) Commissioning Committee, led by Ms. Debra Martin, for all their hard work and support of the crew.

«We recognize just how important the submarine force is during this era of great power competition. As part of the nation’s maritime asymmetric advantage over our competitors, we are ready to perform whatever duty is most needed. The crew is hungry to hone our skills at-sea and become an effective fighting unit, and we will work tirelessly to justify the nation’s confidence in us. Today marks the culmination of six years of dedicated work by the men and women who constructed the nation’s newest and most capable warship. We are all honored to be part of this historic moment», Phillips said. «We are also grateful for the families who have supported our sailors through the long process of bringing this warship to life and dedicated their time with patriotism and selfless devotion».

USS Vermont (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 second Vermont, Battleship No. 20, was commissioned in 1907 and first deployed in December of that same year as part of the «Great White Fleet». She was decommissioned June 30, 1920.

USS Vermont (SSN-792) is a flexible, multi-mission platform designed to carry out the seven core competencies of the submarine force: anti-submarine warfare; anti-surface warfare; delivery of special operations forces; strike warfare; irregular warfare; intelligence, surveillance and reconnaissance; and mine warfare.

The submarine is 377 feet/114.8 m long, has a 34-foot/10.3632-meter beam, and will be able to dive to depths greater than 800+ feet/244+ m and operate at speeds in excess of 25+ knots/28+ mph/46.3+ km/h submerged. The ship’s construction began in May 2014, and it will provide the Navy with the capabilities required to maintain the nation’s undersea superiority well into the 21st century. It is the first the first of 10 Virginia-class Block IV submarines. Block IV submarines incorporate design changes focused on reduced total ownership cost. By making smaller-scale design changes, the U.S. Navy will increase the length of time between maintenance stops and increase the number of deployments.

Christening of Oregon

The U.S. Navy christened its newest attack submarine, the future USS Oregon (SSN-793), during a 10 a.m. EDT ceremony Saturday, October 5, 2019, at General Dynamics Electric Boat in Groton, Connecticut.

Navy christened submarine USS Oregon (SSN-793)

Representative Greg Walden of Oregon delivered the ceremony’s principal address. The submarine’s sponsor was Mrs. Dana Richardson. The ceremony was highlighted by Mrs. Richardson breaking a bottle of sparkling wine across the bow to formally christen the ship, a time-honored Navy tradition.

«The future USS Oregon will play an important role in the defense of our nation and maritime freedom», said Secretary of the Navy Richard V. Spencer. «She stands as proof of what teamwork – from civilian to contractor to military – can accomplish. I am confident USS Oregon and her crew will ensure our Navy remains safe and strong to proudly serve our nation’s interest for decades to come».

Oregon, a Virginia-class submarine designated SSN-793, is the third U.S. Navy ship to honor the state. The first USS Oregon was a brigantine ship purchased in 1841 and used for exploration until 1845. The second Oregon (Battleship No. 3) was commissioned on July 15, 1896. Known for one of the most dramatic voyages ever undertaken by a ship of the U.S. Navy, Oregon sailed over 14,000 miles in 66 days, leaving San Francisco in 1898 and travelling south through the Straits of Magellan until finally arriving at Jupiter Inlet, Florida, where she reported for battle in the Spanish-American War. While the ship demonstrated the capabilities of a heavy battle ship, it also eliminated any opposition to the construction of the Panama Canal, as the country could not afford two months to send warships from one coast to another in times of emergency. Decommissioned in 1906, she was later recommissioned in 1911, and remained in the reserve, until stricken from the Navy list in 1942.

The USS Oregon (SSN-793) is the 20th Virginia-class attack submarine and the second Virginia-class Block IV submarine. The ship began construction fall of 2014 and is expected to deliver in the fall of 2020. Oregon will provide the Navy with the capabilities required to maintain the nation’s undersea superiority well into the 21st century.

Block IV Virginia-class submarines include design changes to Reduce Total Ownership Cost (RTOC) and increase operational availability by decreasing the planned number of depot availabilities from four to three.

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.

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.

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.

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.
