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.

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

«For our shipbuilders, launching Montana signifies five years of hard work, commitment and dedicated service», said Jason Ward, Newport News’ vice president of Virginia-class submarine construction. «We look forward to executing our waterborne test program, and working toward sea trials and delivering the submarine to the U.S. Navy later this year».

Through the teaming agreement with General Dynamics Electric Boat approximately 10,000 shipbuilders, as well as suppliers from all 50 states, have participated in Montana’s construction since the work began in 2015. Montana is approximately 92% complete and scheduled to be delivered to the U.S. Navy in late 2021.

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 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 for months at a time.

Christening of Montana

In its first ceremony celebrating the U.S. Navy’s newest fast-attack submarine in front of a virtual audience, Huntington Ingalls Industries (HII) christened pre-commissioning unit Montana (SSN-794) on September 12, 2020 at the company’s Newport News Shipbuilding division.

Due to COVID-19 restrictions on the size of public gatherings, the christening ceremony was hosted virtually at Newport News’ Module Outfitting Facility.

«Yes, we are disappointed we couldn’t host the normal pomp and circumstance today, and that our shipbuilders and their families couldn’t be here in person to witness history. But as shipbuilders, we know the show must go on», said Jennifer Boykin, president of Newport News Shipbuilding. «Our work doesn’t stop for a pandemic, just as the Navy’s mission never ends. It is our honor, our duty and our calling to keep the wheels of shipbuilding turning, and in doing so, bring Montana one step closer to her ultimate mission of defending the United States of America».

Boykin also applauded the work and craftsmanship of more than 10,000 shipbuilders from Newport News and its partner, General Dynamics Electric Boat who continue to assemble Montana. She also acknowledged the support of the supplier base – more than 5,000 companies in all 50 states – that provided parts and materials critical to Montana’s construction.

Former Secretary of the Interior Sally Jewell, the ship’s sponsor, smashed a bottle of sparkling wine across the bow to mark the christening of the submarine that honors the state of Montana.

«I am grateful to the shipbuilders and dedicated Navy officers and crew for building and readying Montana for service to our nation and the world», Jewell said. «It is a privilege to bless and christen this incredible submarine, and to join the current and future submariners as their shipmates for life».

The virtual event included pre-taped segments where maid of honor Mariah Gladstone, of the Blackfeet Nation in Montana, recited a Native American blessing and members of the Confederated Salish and Kootenai Tribes, of Flathead Indian Reservation, performed a traditional Native American honor song. Representative Robert C. Scott, of Virginia; members of the Montana congressional delegation including Senators Jon Tester and Steve Daines, as well as Representative Greg Gianforte; and General Dynamics Electric Boat President Kevin Graney also offered pre-recorded remarks celebrating the ship’s milestone.

Vice Admiral Richard P. Snyder, the U.S. Navy’s inspector general, also was in attendance.

In his keynote address, Acting Undersecretary of the Navy Gregory J. Slavonic said: «Montana will enhance our fleet with next generation stealth, surveillance and special warfare capabilities. This powerful platform is proof of an ironclad relationship between the U.S. Navy and industrial partners who form the backbone of our maritime strength. While this submarine has the capacity to project power on the surface and undersea, it’s important to recognize the people in every stage of bringing this ship to life because our people make a difference. Montana is proof of what teamwork of all the people – civilian, contractor and military – can accomplish together».

PCU Montana is the second U.S. Navy warship bearing the state’s name. The first USS Montana (ACR-13) was an armored cruiser built at Newport News Shipbuilding and launched in 1906. During the ceremony, a replica of the bell that sailed on the first Montana was rung. The bell will be formally presented to the crew at the ship’s commissioning, and will be part of the submarine for its entire service life.

«Today is an exciting day for the Navy and the crew as our sponsor christened the Navy’s newest Virginia-class submarine, the Montana», said Captain Mike Delaney, commanding officer of the pre-commissioning unit. «While the coronavirus precluded most of the crew’s participation in this ceremony, it in no way diminishes the great accomplishment. I couldn’t be prouder of the way the crew of Montana alongside our shipbuilding partners have adapted to the new normal and focused on responsibly living up to our mission. This is not all too surprising given the innate resiliency and toughness I’ve seen my whole career in the submarine force. This submarine, like all the individuals who have contributed to getting it to this major milestone, will stand as a reflection of strength through adversity».

Three of Montana’s crew members hail from the state of Montana.

Construction of Montana began in 2015 under a teaming agreement with Electric Boat. The submarine achieved pressure hull complete earlier this year, and is about 85% complete. USS Montana (SSN-794) is scheduled for delivery to the U.S. Navy in late 2021.

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.

«This is an important day for us», said Dave Bolcar, Newport News’ vice president of submarine construction. «Not only are we celebrating a milestone in the construction of Montana, we also are recognizing the hard work of the 4,000 shipbuilders who are supporting the construction of newest Virginia-class attack submarine».

In keeping with a U.S. Navy tradition, former Secretary of the Interior Sally Jewell, the ship’s sponsor, chalked her initials onto a steel plate. Mariah Gladstone, a member of the Blackfeet Nation in Montana, performed a Native American blessing.

«It’s a true honor to meet the commander, crew and shipbuilders who are hard at work shaping this amazing submarine to serve our nation», Jewell said. «We celebrate the tradition of the keel laying and look forward to blessing her, christening her and ensuring that the natural beauty, rich culture and spirit of the great state of Montana accompany the ship and crew throughout her lifetime».

Jacob McNulty, a welder at Newport News who was born in Montana, traced Jewell’s inscription on the plate, which signified that the keel of Montana is «truly and fairly laid». The steel plate will be permanently affixed to the submarine.

«The keel laying marks the first milestone for the crew in the construction process of Montana», said Commander Mike Delaney, commanding officer of the pre-commissioning unit. «We are excited to begin this journey and bring the Montana to life over the next few years».

Construction of Montana began in May 2015. The boat is approximately 46 percent complete and is expected to be delivered in late 2020. Two of its crew members hail from the state of Montana.
