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.

«The start of fabrication for one of the U.S. Navy’s most critical assets is always a significant milestone for our shipbuilders», Ingalls Shipbuilding President Brian Cuccias said. «We look forward to leveraging our unparalleled shipbuilding expertise to construct the nation’s newest, most capable destroyer».

The destroyer’s name honors former U.S. Sen. Jeremiah Denton, a Vietnam War veteran who was awarded the Navy Cross for his heroism while a prisoner of war. After graduating from the U.S. Naval Academy in 1946, Denton went on to serve in the Navy for 34 years as a test pilot, flight instructor and squadron leader. Following decades of military service, Denton was elected to the Senate in 1980 where he represented the state of Alabama for six years.

Denton was born in Mobile, Alabama on July 15, 1924. His wife, the former Kathryn Jane Maury, served as ship’s sponsor of the Ingalls-built Aegis guided missile cruiser USS Mobile Bay (CG-53) which was christened in 1985.

Ingalls has delivered 32 Arleigh Burke-class destroyers to the Navy. Other destroyers currently under construction include USS Frank E. Peterson Jr. (DDG-121), USS Lenah H. Sutcliffe Higbee (DDG-123), USS Jack H. Lucas (DDG-125) and USS Ted Stevens (DDG-128).

Arleigh Burke-class destroyers are highly capable, multi-mission ships and can conduct a variety of operations, from peacetime presence and crisis management to sea control and power projection, all in support of the United States’ military strategy. The guided missile destroyers are capable of simultaneously fighting air, surface and subsurface battles. The ship contains myriad offensive and defensive weapons designed to support maritime defense needs well into the 21st century.

The new REMUS 100 UUVs have advanced core electronics and endurance of up to 12 hours. Built on the REMUS Technology Platform, the vehicles are open architecture and have enhanced modularity.

«We value our ongoing partnership with the German Navy and are proud to help enhance their national security capabilities», said Duane Fotheringham, president of Technical Solutions’ Unmanned Systems business group. «Their new REMUS 100s will provide the latest technology to assist them in conducting their MCM operations».

The German Navy previously acquired legacy REMUS 100 UUVs after extensive trials by the Federal Office of Defense Technology & Procurement. For the past seven years, the German Navy has been using these successfully for area search, debris field mapping, and topographic ocean floor mapping in water down to 100 meters/328 feet. The UUVs are outfitted with side scan sonar, using sound to create images of the ocean floor and increasing search efficiency in low visibility areas.

HII collaborated with J. Bornhöft Industriegeräte GmbH, exclusive provider of HII’s REMUS to Germany-based customers, to deliver this technology to the German Navy. Germany is one of 12 NATO member countries, including the United States, which use REMUS UUVs.

Attack Submarine

Huntington Ingalls Industries’ (HII) Newport News Shipbuilding division hosted a keel authentication ceremony on December 11, 2020 for Virginia-class attack submarine USS Massachusetts (SSN-798). Due to the COVID-19 pandemic, the event was held virtually, without an audience.

Sandberg (center left) delivered pre-recorded remarks during the event, which marks the ceremonial start of construction. Present was Newport News Shipbuilding President Jennifer Boykin (left); Commander Erik Lundberg, commanding officer of the pre-commissioning unit (center) and welder Ronnie Payne (Photo by Ashley Cowan/HII)

«This construction milestone is typically a small ceremony with shipbuilders and the submarine’s crew in attendance», said Jennifer Boykin, president of Newport News Shipbuilding. «Given the current COVID-19 environment and the precautions it requires, today’s event is smaller than usual in scope, but not in importance».

«Today’s event is a significant milestone in the life of the boat because it is the official construction kickoff, but it also marks the beginning of an important partnership between our shipbuilders who will build this mighty war vessel and the sailors who will bring her to life», Boykin added.

Sheryl Sandberg, chief operating officer of Facebook, is the ship’s sponsor. In a pre-recorded video message, Sandberg etched her initials onto a metal plate, signifying the keel of SSN-798 as being «truly and fairly laid».

Ronnie Payne, a master shipbuilder who has worked on every Virginia-class submarine built at Newport News, then traced Sandberg’s initials with a welding torch at the company’s Supplemental Module Outfitting Facility. The metal plate will remain affixed to the ship throughout its life.

«This year has been difficult for so many, and I am extra grateful for moments like this one when we can celebrate such an important milestone together», Sandberg said. «I have a deep respect for the shipbuilders who will bring this vessel to life. I am so grateful for the opportunity to build a lifelong bond with this boat and its crew in my role as the sponsor».

USS Massachusetts (SSN-798) is the 25th Virginia-class fast attack submarine being built under the teaming agreement with General Dynamics Electric Boat. Construction began in March 2017 and is approximately 50% complete. The boat is scheduled for delivery to the Navy in 2023.

«One of the privileges in establishing a command from the very beginning is developing a relationship with the boat’s namesake state – a relationship inherited from our forebears and one that will last the life of the ship and beyond», said Commander Erik Lundberg, commanding officer of the pre-commissioning unit. «Our mission is clear – deliver the most advanced, most capable warship to the Navy and our nation with an equally advanced and capable crew to bring her to life. The crew of Massachusetts stands ready».

«Every successful sea trial is a major accomplishment for our shipbuilders, but this set proved to be a particularly substantial undertaking», said Jay Boyd, Ingalls’ NSC program manager. «Since the year began, our team has persevered through every challenge. Learning through each obstacle presented by the COVID-19 pandemic, the NSC team has worked tirelessly to ensure the Coast Guard receives another high performance cutter to help protect our nation».

In the weeks preceding NSC-9 builder’s trials, safety precautions were put in place to minimize the potential risk of COVID-19 to participants while at sea. The number of shipboard riders was reduced by one-third to allow for adequate social distancing. Those allowed onboard were tested for COVID-19 one week prior to sail, and were screened the morning of departure. Masks were required at all times, food services were staggered, and in addition to the cutter’s regular cleaning regimen, each individual received their own personal supplies to clean their way in and out of spaces onboard the ship.

Ingalls has delivered eight Legend-class NSCs with two more under construction, and one additional under contract. USCGC Stone (WMSL-758), the ninth NSC, is scheduled for delivery later this year.

NSC-9 was named to honor Coast Guard officer Commander Elmer «Archie» Fowler Stone, Coast Guard aviator number one, who made history in 1919 for being one of two Coast Guard pilots in the four man air crew who completed the first transatlantic flight in a Navy seaplane.

The Legend-class NSC is the largest, most technologically advanced ship in the Coast Guard’s fleet, which enables it to meet the high demands required for maritime and homeland security, law enforcement, marine safety, environmental protection and national defense missions.

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.
