First British Ares

Named for the ancient Greek god of war, Ares delivers a step-change in the British Army’s battlefield capability. Last week, the first six vehicles were delivered to the Household Cavalry Regiment at Bulford, Wiltshire.

First Ares Armoured Vehicles Delivered to the Army

Ares, and the other variants in the Ajax family of armoured vehicles, will replace the Army’s Combat Vehicle Reconnaissance (Tracked) (CVR(T)) vehicles which have been the mainstay of armoured reconnaissance for almost fifty years.

CVR(T) has proved itself on the battlefield in the Falklands and the in the deserts of the Middle East, but now requires a replacement to maintain the Army’s position as a top tier performer and to match the needs of the twenty-first century.

The Ajax family consists of Ares a troop-carrying reconnaissance vehicle, Ajax armed with a formidable 40-mm cannon, support variants Apollo and Atlas, a command and control variant Athena, and an engineer variant – Argus.

Ares, part of the Ajax family of armoured vehicles, is being built by General Dynamics in Merthyr Tydfil, bringing hundreds of jobs and wider opportunities to Wales. The vehicles will give the Army’s Armoured Infantry and Strike Brigades a critical advantage over any likely opponent, through a combination of the latest technology, exemplary levels of crew protection, and, of course, our world-class professional soldiers.

Colonel Justin Kingsford, the Ajax Programme Director said: «This is an exciting moment for the Army. The delivery of Ares this week is an important step on our journey to give the Army an amazing state of the art, world beating Armoured Fighting Vehicle».

Describing the vehicle in greater depth, he went on to say: «Ajax will allow us to manage battlespace information faster from a modern digitised platform, with increased lethality through the new 40-mm cannon. Better mobility, alongside enhanced protection levels and increased reliability underline the transformational nature of the capability. A comprehensive simulated training suite supports this fleet and ensures we invest fully in our crews to get the very best of this capability».

Expeditionary Sea Base

Construction of the fourth Expeditionary Sea Base (ESB) ship officially began on June 25 at the General Dynamics National Steel and Shipbuilding Company (GD-NASSCO) shipyard in San Diego, California. Due to the COVID pandemic, the milestone was marked with an informal shipyard ceremony.

Expeditionary Sea Base ships are highly flexible platforms that are used across a broad range of military operations supporting multiple operational phases. Acting as a mobile sea base, they are part of the critical access infrastructure that supports the deployment of forces and supplies to provide prepositioned equipment and sustainment with flexible distribution.

«This is a great Navy day as we mark the start of construction on the fourth ship in a class of flexible, adaptable ships that will provide our combatant commanders with enhanced capabilities», said Tim Roberts, Strategic and Theater Sealift program manager, Program Executive Office (PEO), Ships. «The ESB platform has proven to be a valuable addition to the Navy and Marine Corps battle force».

Expeditionary Sea Bases support Aviation Mine Countermeasure and Special Operations Force missions. In addition to the flight deck, the ESB has a hangar with two aviation operating spots capable of handling MH-53E Super Stallion equivalent helicopters, accommodations, work spaces, and ordnance storage for embarked force, enhanced Command, Control, Communications, Computers, and Intelligence (C4I) to support embarked force mission planning and execution and reconfigurable mission deck area to store embarked force equipment to include mine sleds and Rigid Hull Inflatable Boats (RHIBs).

In 2019, the U.S. Navy made the decision to commission all Expeditionary Sea Base ships to allow them to conduct a broader and more lethal mission set, compared to original plans for them to operate with a USNS designation. ESBs are commanded by a Navy O-6 with a hybrid-manned crew of military personnel and Military Sealift Command civilian mariners. This designation provides combatant commanders greater operational flexibility as to how the platform is employed.

In addition to ESB-6, NASSCO is under contract for the construction of ESB-7, with an option for ESB-8, as well as the U.S. Navy’s John Lewis Class Fleet Replenishment Oilers (T-AO 205 – 210).

As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, boats and craft.

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.

Following this delivery, the ship will transition from Combat Systems Activation to the next phase of developmental and integrated at-sea testing. This event marks a major milestone of the dual delivery approach for USS Zumwalt (DDG-1000), which achieved Hull Mechanical & Electrical delivery from shipbuilder General Dynamics’ Bath Iron Works in May 2016. Raytheon Integrated Defense Systems was the prime contractor for the Zumwalt Combat System, and has lead activation and integration for Zumwalt class ships both in Bath, Maine and San Diego.

«Delivery is an important milestone for the Navy, as DDG-1000 continues more advanced at-sea testing of the Zumwalt combat system», said Captain Kevin Smith, DDG-1000 program manager, Program Executive Office, Ships. «The combat test team, consisting of the DDG-1000 sailors, Raytheon engineers, and Navy field activity teams, have worked diligently to get USS Zumwalt (DDG-1000) ready for more complex, multi-mission at-sea testing. I am excited to begin demonstrating the performance of this incredible ship».

With delivery, USS Zumwalt (DDG-1000) joins the U.S. Pacific Fleet battle force and remains assigned to Surface Development Squadron One. In addition to at-sea testing of the Zumwalt combat system, DDG 1000 will also operate as a key enabler in the acceleration of new warfighting capabilities and rapid development and validation of operational tactics, techniques, and procedures.

The 610-foot/186-meter, wave-piercing tumblehome ship design provides a wide array of advancements. Employing an innovative and highly survivable Integrated Power System (IPS), DDG-1000 has the capacity to distribute 1000 volts of direct current across the ships’ entirety, allowing for enhanced power capability for various operational requirements. Additionally, the shape of the superstructure and the arrangement of its antennas significantly reduce radar cross section, making the ship less visible to enemy radars.

«Every day the ship is at sea, the officers and crew learn more about her capability, and can immediately inform the continued development of tactics, techniques, and procedures to not only integrate Zumwalt into the fleet, but to advance the Navy’s understanding of operations with a stealth destroyer», remarked Captain Andrew Carlson, the Commanding Officer of USS Zumwalt (DDG-1000). «After sailing over 9000 miles and 100 days at sea in 2019, we are absolutely looking forward to more aggressive at-sea testing and validation of the combat systems leading to achievement of initial operational capability».

The USS Zumwalt (DDG-1000) is the first ship of the Zumwalt-class destroyers. The USS Michael Monsoor (DDG-1001) is homeported in San Diego and is undergoing combat systems activation. The third and final ship of the class, the future USS Lyndon B. Johnson (DDG-1002), is under construction at BIW’s shipyard in Bath, Maine.

As one of the Defense Department’s largest acquisition organizations, PEO Ships is responsible for executing the development and procurement of all destroyers, amphibious ships, special mission and support ships, and special warfare craft.

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.

The USS Hershel «Woody» Williams (T-ESB-4) is the first ship to bear the name of Marine Corps Chief Warrant Officer Four Hershel Woodrow Williams, the last surviving Medal of Honor recipient recognized for heroism at the Battle of Iwo Jima during World War II.

U.S. Senator Joe Manchin of West Virginia delivered the commissioning ceremony’s principal address. The ceremony was highlighted by a time-honored Navy tradition when Ms. Tracie Jean Ross and Ms. Travie Jane Ross, ship sponsors and daughters of Hershel «Woody» Williams, gave the first order to «man our ship and bring her to life»!

«This ship honors a man who dedicated his life to service – heroic service as a Marine, and continued service to his fellow veterans», said Acting Secretary of the U.S. Navy Thomas Modly. «This dedication will live on in USS Hershel ‘Woody’ Williams as the ship is deployed around the world bringing additional capability to our growing fleet. The ceremony on Saturday will also represent the dedication to service demonstrated by the men and women who worked tirelessly to build this ship and their commitment to quality and innovation».

The USS Hershel «Woody» Williams (T-ESB-4) is optimized to support a variety of maritime-based missions and designed around four core capabilities: aviation facilities, berthing, equipment staging support, and command and control assets. ESBs can be enhanced to meet special operations force missions through increased communications, aviation and unmanned aircraft system support.

Built by General Dynamics National Steel and Shipbuilding Company (NASSCO), the Montford Point-class is comprised of five ships across two variants: Expeditionary Transfer Docks and Expeditionary Sea Bases. Acting as a mobile sea base, ESBs are part of the critical access infrastructure that supports the deployment of forces and supplies to provide prepositioned equipment and sustainment with flexible distribution.

The platform has an aviation hangar and flight deck that include four operating spots capable of landing V-22 Osprey and MH-53E Super Stallion equivalent helicopters, accommodations, work spaces, and ordnance storage for an embarked force. The platform will also provide unmanned aviation vehicle operations, enhanced command and control, communications, computers, and intelligence capabilities to support embarked force mission planning and execution. The reconfigurable mission deck area can store embarked force equipment including mine sleds and rigid hull inflatable boats.
