Block IV Aperture Array

Northrop Grumman Corporation has delivered the first shipset of Light Weight Wide Aperture Array (LWWAA) hardware for Block IV of the Virginia Class Submarine (VCS) to the U.S. Navy. This represents the 19th shipset that Northrop Grumman has supplied for the VCS program.

LWWAA is the only available fiber-optic passive hull mounted sensor array in the market and is critical to the operation of the U.S. Navy’s VCS fleet

LWWAA is the only available fiber-optic passive hull mounted sensor array in the market and is critical to the operation of the U.S. Navy’s VCS fleet. The technology is central to the development of future generations of undersea sensors. There are six arrays in each shipset.

«LWWAA gives the Navy a distinctive edge over sensors being used by any other naval force», said Alan Lytle, vice president, undersea systems, Northrop Grumman Mission Systems. «The early delivery of this first Block IV LWWAA shipset continues a tradition of 114 consecutive early array deliveries by Northrop Grumman Undersea Systems in support of the Virginia Class Submarine program».

Northrop Grumman has been delivering LWWAA panels for all VCSs, starting with the USS Virginia, SSN-774. The start of the first Block IV shipments represents the beginning of a series of 10 shipments that will be delivered at a rate of two per year to Huntington Ingalls Industries. Northrop Grumman will provide the acoustic array assemblies as well as all the hardware required to install the arrays on the exterior of the ships.

Sea Ready

The Navy’s newest submarine was delivered to the U.S. Navy with nearly 100 percent on board material August 26, thanks to the collaboration between the ship’s supply department and Naval Supply Systems Command (NAVSUP) Fleet Logistics Center (FLC) Norfolk, Groton Division.

According to Assistant Division Director Lieutenant Joseph Aiello, USS Illinois (SSN-786) was delivered ahead of schedule with 99.51 percent on board material – well above the contractual requirement of 97 percent.

Behind the scenes, a small cadre of logistic specialists quietly executed the functions of outfitting and stowing the Navy’s newest submarine. The team tracked and monitored the delivery of more than 10,000 items to include all Authorized Medical Allowance List (AMAL), Authorized Dental Allowance List (ADAL), General Use Consumables List (GUCL), and Government Furnished Equipment (GFE) to the submarine.

«Beyond the hull of Illinois, the most valuable asset – the crew – was provided with dedicated support facilities to ensure training, administration and day-to-day operations of the command continued unencumbered by the construction», said Aiello.

NAVSUP FLC Norfolk, Groton Division is a relatively small unit comprised of 19 civilian and military personnel.

«The single aspect that, to me, is most inspiring about the organization is the sheer dedication to the Sailors on the waterfront and the true collaborative nature that is fostered across the spectrum of organizations at the shipyard», said Aiello.

According to Aiello, collaboration between civilian employees and military staff is a noted organizational strength of the unit.

«While a good segment of the team have prior military experience, those who do not have demonstrated the same commitment to excellence and truly understand the need for flawless customer support», he added.

USS Illinois (SSN-786), which is the 13th submarine in the Virginia class, is scheduled to be commissioned October 29.

Pressure Hull Complete

Huntington Ingalls Industries (HII) announced on August 9 that its Newport News Shipbuilding division has reached a major milestone in the construction of the submarine USS Indiana (SSN-789). The 16th Virginia-class submarine has reached «pressure hull complete», signifying that all of its hull sections are joined to form a single, watertight unit.

Ship’s Sponsor Diane Donald, wife of Admiral Kirk Donald (U.S. Navy, Ret.), and Ray Shearer, chairman of Indiana’s commissioning committee, visited the shipyard to see the progress being made on the submarine and meet with its crew.

«Witnessing Indiana come to life is one of the most gratifying experiences of my life», Mrs. Donald said. «The countless hours of hard work the shipbuilders have put into constructing and perfecting this boat is apparent, as Indiana has now taken on the shape of a submarine. I also had the pleasure of spending time with the ship’s crew. As the wife of a submariner, it’s been a real honor getting to know a new generation of sailors and witnessing their enthusiasm and dedicated service to our nation. As Indiana moves closer to joining the Navy’s fleet next year, I look forward to continuing to share this journey with her shipbuilders and crew members».

Pressure hull complete is the last major milestone before the submarine’s christening. Construction began in September 2012 under a teaming agreement between Newport News and General Dynamics Electric Boat. The submarine is about 82 percent complete and is scheduled for delivery to the Navy in the third quarter of 2017.

«We are on track to meet our budget and schedule commitments to the Navy, and I’m proud of the progress that the Newport News Shipbuilding-General Dynamics Electric Boat team is making», said Jim Hughes, Newport News’ vice president, submarines and fleet support. «Our progress demonstrates the efficiency of the Navy’s two-per-year build plan, which helps ensure America’s undersea superiority».

Commander Jesse J. Zimbauer, Indiana’s commanding officer, said, «Newport News Shipbuilding has completed the pressure hull on time for the Indiana, continuing the momentum of the Navy’s most successful build program and moving us another step closer to taking our submarine to sea».

Keel for Indiana

The keel of the 16th Virginia-class attack submarine, named after the 16th largest state, was laid May 16 at Newport News Shipyard. She is the third ship to bear the name Indiana, and will be the first in almost 70 years to sail under the national colors with that name. It is said in the Navy Times that the ship’s sponsor, Diane Donald, the wife of retired Admiral Kirk Donald, a former director of Naval Nuclear Propulsion, declared the keel «to be truly and fairly laid». Diane Donald authenticated the keel with her initials, which were welded onto a metal plate and permanently affixed to the ship.

Construction on Indiana, the sixth of eight Block III variants, started in September 2012. The state is known as «the crossroads of America», and its namesake honors that motto well. She carries millions of parts from 5,000 suppliers located in all 50 states. Assembling these parts is what Jim Hughes, vice president for Submarines and Fleet Support, called «one of the biggest orchestras in the world». The symphony carefully played by 4,000 shipbuilders will now unite hull sections into a 377-foot/114.8 m military masterpiece that will crescendo with its 2017 commissioning, then slip into three decades of silent service.

Her missions will be many and multifaceted. The Virginia class has a large lock-in/lock-out chamber, and a reconfigurable torpedo room to accommodate more snake eaters. She will carry roughly three dozen Tomahawk cruise missiles. Traditional periscopes have been replaced by photonics masts with high-resolution cameras and infrared sensors. A fly-by-wire ship control system provides unmatched operation in shallow littoral areas.

While the Virginia class boasts these and other upgrades in weaponry and other tactical equipment, its biggest edge is in acoustics, said Commander Jesse Zimbauer, the ship’s skipper. Among its many advances, the Block III variant vastly improved passive detection by replacing the traditional sonar sphere with the Large Aperture Bow array. «We are building the future with this submarine», said Jesse Zimbauer, who «jumped on the opportunity» to be part of the pre-commissioning unit.

A keel laying is the symbolic beginning of building a ship, originating from the large structural beam, or keel, that serves as the foundation or spine of the ship’s hull. Although modular construction techniques mean that the ship is no longer built from the bottom up, the keel laying is still celebrated as a momentous event in the ship’s construction. During the keel laying ceremony, the ship’s sponsor authenticates the keel by chalking her initials onto a metal plate. The initials are then welded onto a plate that is permanently affixed to the ship.
