USS Arkansas (SSN-800) is now «pressure hull complete», meaning that all of the hull sections were joined to form a single, watertight unit.

«It’s exciting to reach pressure hull complete, because it’s a visible sign that construction has progressed to the point where Arkansas really starts to take its final shape», said Jason Ward, NNS vice president of Virginia-class submarine construction. «We absolutely understand the important mission ahead for Arkansas and are working with urgency to get this powerful national security asset to the Navy as soon as possible».

NNS is one of only two shipyards capable of designing and building nuclear-powered submarines. The advanced capabilities of Virginia-class submarines increase firepower, maneuverability and stealth.

This milestone comes following the christening of USS Massachusetts (SSN-798) and keel authentication of USS Oklahoma (SSN-802) at NNS so far in 2023.

Arkansas is the Navy’s 27th Virginia-class fast attack submarine. The ship’s sponsors are the six women of the historic group known as the Little Rock Nine, the first African American students to attend all-white Central High School in Little Rock, Arkansas, during desegregation. NNS honored all nine members, including the three men, during the November 2022 keel authentication ceremony.

Christening of Iowa

The U.S. Navy christened one of its newest Virginia-class fast-attack submarines, the future USS Iowa (SSN-797), during a 10 a.m. EDT ceremony Saturday, June 17, 2023, General Dynamics Electric Boat in Groton, Connecticut.

The principal speaker was the Honorable Erik Raven, Under Secretary of the Navy. Remarks also were provided by the Honorable Senator Richard Blumenthal; Vice Admiral Frank Morley, principal military Deputy Assistant Secretary of the Navy (Research, Development and Acquisition); Mr. Kevin Graney, president of Electric Boat; Mr. Bryan Caccavale, vice president, Huntington Ingalls Newport News Shipbuilding; U.S. Representative, Iowa’s 3rd District, Zach Nunn; and U.S. Representative, Connecticut’s 2nd District, Joe Courtney

In a time-honored Navy tradition, the submarine’s sponsor, Mrs. Christie Vilsack, christened the boat by breaking a bottle of sparkling wine across the bow. Vilsack, an Iowa native, most recently served as the education advisor to the chancellor of Colorado State University. She also served as the senior advisor for International Education at USAID during the Obama Administration. As Iowa’s First Lady, she led a focus on education and advocacy for Iowa’s public libraries. She and her husband Mr. Tom Vilsack, the Secretary of Agriculture, live in rural Iowa.

The future USS Iowa (SSN-797) is the fourth U.S. Navy vessel and first submarine named in recognition of the state. Previous ships named after the state were battleships, as well as, a converted merchant ship that was never activated.

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. These capabilities allow the submarine force to contribute to regional stability and preservation of future peace while operating everywhere international law allows, so everyone else can too.

The ship’s sponsors are the six women of the historic group known as the Little Rock Nine, the first African American students to attend all-white Central High School in Little Rock, Arkansas during desegregation. NNS honored all nine members, including the three men, during Saturday’s ceremony.

The Little Rock Nine made history in 1957 with their response to the Supreme Court ruling in Brown v. Board of Education, declaring racial segregation in public schools unconstitutional. Faced with shouting mobs, threats of violence and hostile state leaders who blocked their way, the teenagers were escorted into the school by federal troops at the direction of President Dwight D. Eisenhower.

«Their courageous spirit will forever inspire Arkansas and her crew. This group forever changed our nation’s history and their submarine will help ensure their legacy continues», NNS President Jennifer Boykin said. «The bravery and resilience of the Little Rock Nine sparked a fire of change and demonstrated the strength of blending different perspectives and backgrounds. We harness this strength in the shipyard every day. Our diversity allows us to extend beyond our own limits, to reach new heights, and build each boat even better than the one before it. Arkansas will be proof of this power».

During Saturday’s ceremony, NNS welders etched a historic six sets of initials of the Little Rock Nine onto metal plates, signifying the keel of SSN-800 as being «truly and fairly laid». The metal plates will remain affixed to the submarine throughout its life.

«(Former Navy) Secretary Ray Mabus asked us to be supporters of the ship and its crew. I signed on to be a foster grandmother», said Elizabeth Eckford, a member of the Little Rock Nine, who spoke on behalf of the group during the ceremony. «President Eisenhower sent 1,000 paratroopers to Little Rock to disperse a mob, bring order, and they made it possible for us to enter Central High School. From that point, I’ve had very high regard for specially trained forces».

Arkansas is the 27th Virginia-class fast attack submarine being built under the teaming agreement with General Dynamics Electric Boat.

«With advances in sound silencing, acoustic sensors, and weapons delivery systems, Arkansas will traverse the world’s oceans and seas as an apex predator. Representing our asymmetric advantage in the undersea domain, the Arkansas will have no equal», said Vice Admiral William Houston, commander, Naval Submarine Forces.

«It is an incredible honor for the crew to begin to establish the relationship with our namesake state of Arkansas as well as with the ship’s sponsors», said Commander Adam Kahnke, commanding officer of the pre-commissioning unit. «The story of the Little Rock Nine demonstrates the power of perseverance in the face of adversity. I find the relationship with the ship’s sponsors very appropriate due to the fact that perseverance is an essential attribute to success in the art of submarine warfare».

NNS is one of only two shipyards capable of designing and building nuclear-powered submarines. The advanced capabilities of Virginia-class submarines increase firepower, maneuverability and stealth.

This milestone on Arkansas comes following the delivery of USS Montana (SSN-794), the launch of USS New Jersey (SSN-796), and continued progress on USS Massachusetts (SSN-798) at NNS earlier in 2022, as the shipyard continues to invest in its workforce and facilities to make steady progress on delivering these important assets to the U.S. Navy.

Governor Greg Gianforte of Montana delivered the principal address. Additional speakers include U.S. Representative Bobby Scott of Virginia’s 3rd District; Undersecretary of the U.S. Navy Erik Raven; Admiral James Caldwell, director, Naval Nuclear Propulsion Program; and Ms. Jennifer Boykin, president of Newport News Shipbuilding.

The submarine’s sponsor is Sally Jewell, former Secretary of the United States Department of Interior. Montana was christened at Newport News Shipbuilding, a division of Huntington Ingalls Industries, in Newport News, Virginia, on September 12, 2020. Mrs. Jewell gave the order to «man our ship and bring her to life».

The USS Montana (SSN-794) honors the Treasure State and will be the second commissioned warship bearing the name. The first USS Montana (ACR-13), an armored cruiser, was also built at Newport News Shipbuilding and commissioned in July 1908. ACR-13 served in the Atlantic and Mediterranean, landed Marines during unrest in Haiti in 1914, and escorted convoys during World War I. The U.S. Navy decommissioned the first USS Montana in 1921, and two other vessels named after the state never saw commissioned service.

«This boat is a true treasure of the U.S. Navy, and will play an integral part in protecting and promoting American prosperity and security abroad», said Secretary of the U.S. Navy Carlos Del Toro. «I am so proud of the brave men and women who will man this submarine, and I look forward to their success on the high seas».

Montana is the third Block IV Virginia-class submarine to enter service, designed to carry out the core missions 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. These capabilities allow the submarine force to operate anywhere, at any time, and contribute to regional stability and the preservation of future peace.

Montana is 377 feet/114.8 m long, has a 34-foot/10-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. It has a crew of approximately 136 Navy personnel.

The 7,800-ton submarine, which had been in a floating dry dock since being transferred from a construction facility in March, was submerged and moved by tugboats to the shipyard’s submarine pier for final outfitting, testing and crew certification.

«Achieving this construction milestone is a very rewarding event to our shipbuilding team», said Jason Ward, Newport News’ vice president of Virginia-class submarine construction. «Our shipbuilders and suppliers have dedicated years of hard work to this critical capability that will maintain our customer’s undersea superiority. We now look forward to executing our waterborne test program, and working toward sea trials so we can deliver to the Navy».

Through the teaming agreement with General Dynamics Electric Boat, approximately 10,000 shipbuilders, as well as suppliers from 50 states, have participated in New Jersey’s construction since the work began in 2016. New Jersey is approximately 92% complete.

Virginia-class submarines, a class of nuclear-powered fast attack 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 to significantly enhance their warfighting capabilities. These submarines are capable of supporting multiple mission areas and can operate at speeds of more than 25 knots/28 mph/46.3 km/h for months at a time.

USS Montana (SSN-794), which successfully completed sea trials last month, is the 10th Virginia-class submarine to be delivered by HII’s Newport News Shipbuilding division and the 21st built as part of the teaming agreement with General Dynamics’ Electric Boat.

«We continue to be proud of our partnership with the U.S. Navy in delivering the most advanced ships in the world to our warfighters», said Jason Ward, Newport News Shipbuilding vice president of Virginia-class submarine construction. «The results of the Navy’s board of inspection and survey during sea trials are a testament to our priorities of safety and quality. We are proud of our team of shipbuilders for delivering these critical capabilities to the Navy and the nation».

More than 10,000 shipbuilders from Newport News Shipbuilding and Electric Boat have participated in Montana’s construction since the work began in May 2015. The submarine was christened by the ship’s sponsor, former U.S. Secretary of the Interior Sally Jewell, during a ceremony in September 2020.

Montana is the third of the 10-ship group of Virginia-class submarines known as Block IV. 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.

Oregon

Electric Boat (EB) delivered the nuclear-powered attack submarine USS Oregon (SSN-793) to the U.S. Navy on February 26, 2022. Oregon is the 20th submarine of the Virginia Class, which provides the Navy with the capabilities required to retain undersea dominance well into the 21st century. With the other ships of the class, Oregon represents a revolution in submarine design, construction and mission capability. This versatile and powerful vessel – unobtrusive, non-provocative and connected with land, air, sea and space-based assets – will maximize the contribution the U.S. submarine force makes to national security.

«Today is a great day for the Oregon, a great day for the Navy and a great day for Electric Boat», said Pete DiNapoli, ship manager of USS Oregon (SSN-793) at her delivery ceremony on February 28. DiNapoli addressed the shipbuilders of Electric Boat, noting their excellent performance leading up to the significant achievement of delivering EB’s latest contribution to national security. «This journey was not easy, and each and every one of you rose up to the challenge and made it look easy. Shipbuilding is a big team sport, and I thank you all for your hard work».

Stan Gwudz, director of the Virginia program and ship’s management, also offered his acknowledgement of the EB team. «I couldn’t be more proud to be part of a team that makes our Navy the best in the world», said Gwudz.

Sea trials for Oregon, directed by U.S. Navy Admiral Frank Caldwell Jr., director – Naval Nuclear Propulsion, began in December 2021. The trials included a range of submarine and propulsion-plant operations, submerging for the first time, and high-speed runs on and below the surface to demonstrate that the ship’s propulsion plant is fully mission-capable.

«I was on that boat, and I wish every one of you, and really every American, could see what I see on those boats», said Electric Boat President Kevin Graney following Oregon’s Alpha trials. «It is eye-watering, unsurpassed technology. It is sailors who are at the pointy end of the spear and are absolute masters at submarine warfare. It is EB people fiercely proud of what they’ve built».

The Navy’s Board of Inspection and Survey (INSURV) gave the Oregon a score of 95 following her final INSURV trial, continuing the trend of high performance on Virginia-class new construction. Oregon is commanded by Commander Lacy Lodmell.

Oregon is the second of the 10-ship group of Virginia-class submarines known as the Block IV series, continuing a whole new level of capability for the Virginia Class. Increased stealth, improved surveillance and design changes that increase the component-level lifecycle of the submarine and reduce total ownership cost are the hallmarks of this newest attack submarine. By making these smaller-scale design changes to increase the component-level lifecycle of the submarine, the Navy will increase the periodicity between depot maintenance abilities and increase the number of deployments. Blocks I-III of Virginia-class submarines are planned to undergo four depot maintenance availabilities and conduct 14 deployments, while Block IV design changes are intended to reduce these planned availabilities by one to three, increasing deployments to 15.

Virginia-class submarines displace 7,835 tons, with a hull length of 377 feet/114.8 m and a diameter of 34 feet/10.3632 m. They are capable of speeds in excess of 25 knots and can dive to a depth greater than 800 feet/244 m, while carrying Mark-48 advanced capability torpedoes and Tomahawk cruise missiles.

Initial Sea Trials

Huntington Ingalls Industries (HII) announced on February 7, 2022 the successful completion of the initial sea trials Friday of fast-attack submarine USS Montana (SSN-794). The Virginia-class submarine, built at HII’s Newport News Shipbuilding division, spent several days at sea to test the ship’s systems and components.

Testing included submerging the submarine for the first time and high-speed maneuvers while on the surface and submerged. HII teams will continue the testing program and will deliver the boat to the U.S. Navy later this year.

«We are very proud to say the Montana and her crew performed exceptional», said Jason Ward, Newport News Shipbuilding vice president of Virginia-class submarine construction. «Taking the ship to sea for the first time is a huge milestone for everyone involved. The crew, thousands of suppliers from around the country and shipbuilders from HII and Electric Boat can be proud the ship was successfully brought to life and will soon be part of the world’s greatest Navy».

Construction of Montana began in 2015. The boat – the 21st Virginia-class submarine built as part of the teaming partnership with General Dynamics’ Electric Boat – was christened in September 2020.
