US Navy awards largest-ever shipbuilding contract to Electric Boat for new attack submarines
By: David B. Larter
WASHINGTON – The U.S. Navy on Monday awarded its largest-ever shipbuilding contract to General Dynamics Electric Boat for construction of nine Virginia-class attack submarines, eight of which will have 84-foot section that boosts the boat's strike missile capacity.
The contract for the Block V Virginias, worth $22.2 billion, could grow by another $2 billion if the Navy exercises an option for a 10th boat. The contract is for two fewer boats than the 11 proposed by the fleet in this year's budget submission.
“A lot of hard work across the whole team to structure the contract in such a was as to balance risk between the government and the shipbuilder,” said James Geurts, the Navy's top acquisition official, in a roundtable with members of the media to announce the contract signing. “If the shipbuilder delivers on target, the multi-year savings will be 16.5 percent, or $4.4 billion in savings. So, it's a pretty important day for us.”
Guerts, the assistant Secretary of the Navy for research, acquisition and development, said that when you add government furnished equipment into the contract, the total swells to about $35 billion.
The first boat in Block V, SSN 802, is currently under construction but does not have the Virginia Payload Module. The next boat, 803, will have VPM. All of the boats will have an upgraded acoustics suite.
In the briefing, Navy officials said that six of the boats would be constructed at Electric Boat's partner yard, Huntington Ingalls Newport News, and three would be built at Electric Boat. The 10th boat would go to Electric Boat if the Navy exercised the option.
The move to put most of the work in Newport News was done to balance the increased workload at Electric Boat with the start of the Columbia class, the next generation of ballistic missile submarines slated to begin construction this year.
In a statement, Electric Boat President Kevin Graney said the contract provides stability for his shipyard.
“This contract allows for our shipbuilding team, out suppliers and our employees to plan ahead so that we can continue to deliver submarines of unmatched quality, stealth and lethality,” Graney said.
Dave Bolcar, Newport News' vice president of submarine construction, likewise hailed the contract as a means of stability in the submarine industrial base.
"Today's contract maintains the Virginia-class build rate that provides continued stability to our workforce and to the 5,000 suppliers that will support submarines for the next decade,” he said. "This contract also continues the two per year construction cadence essential to sustaining production efficiencies, while ensuring our national security and the Navy's continued undersea superiority.”

Enabling Revolutionary Nondestructive Inspection Capability
X-rays and gamma rays have a wide range of applications including scanning suspicious maritime shipping containers for illicit materials, industrial inspection of materials and processes, and medical diagnostic and therapeutic procedures. Current technologies, however, are not ideal. X-rays produce a continuum of energies that limit their inspection and diagnostic performance, and gamma rays can only be produced at specific energies unique to a given radioactive isotope. DARPA today announced its Gamma Ray Inspection Technology (GRIT) program. GRIT seeks novel approaches to achieve high-intensity, tunable, and narrow-bandwidth sources of gamma ray radiation in a compact, transportable form factor that would enable a wide range of national security, industrial, and medical applications. A Proposers Day webinar describing the goals of the program is scheduled for July 8, 2019. “What we're trying to do in GRIT is transform the use of x-rays and gamma rays,” said Mark Wrobel, program manager in DARPA's Defense Sciences Office. “Current sources of gamma rays, like Cobalt-60 or Cesium-137, are not very flexible. They require special licenses to possess and only emit gamma rays at very specific energies. What we desire is a source of very high-energy photons that we can tune to match the application we need. This ranges from more effective detection of illicit cargo, to a more informative medical x-ray.” GRIT aims to provide a source of tunable, pure x-rays and gamma rays from tens of keV (kilo-electron volts) up through over ten MeV (mega-electron volts). Currently, tunable and narrow bandwidth gamma ray sources only exist at highly specialized user facilities best suited for basic research and are not able to support broad practical applications. Shrinking these photon sources to a transportable system is a major goal and challenge of the GRIT program. GRIT technology could make possible a range of new inspection and diagnostic protocols. In medical and industrial radiography, for example, GRIT could enable revealing specific elemental and material content, such as calcium in bones or specific metals in cargo. A typical x-ray only shows differences in density in the object being inspected – whether a piece of luggage at an airport, or an individual at a doctor's office. If successful, a GRIT x-ray source could be tuned to detect and quantify the concentration of specific elements of interest, such as the amount of calcium in a given bone x-ray, enabling radiologists to actually see bone composition. Tuning energy between 10s of keV to over 100 hundred keV would allow detection of specific elements that might be of interest in characterizing novel materials and processes at micron scales. These techniques would be relevant to defense applications including non-destruction inspection of novel additively manufactured materials and alloys for their elemental composition. At energy levels in the MeV range, gamma ray photons have high enough energy to actually interact with the nuclei of atoms. Whereas x-rays work by interacting with the shells of atoms, GRIT would be able to stimulate the nucleus of an atom to bring about an effect called nuclear resonance fluorescence, a sort of “fingerprint” that is unique to each isotope on the periodic table. “With GRIT, you could probe and detect specific isotopes of interest by fine-tuning the photon energy to minimize background noise and take advantage of the nuclear resonance fluorescence phenomenon,” Wrobel said. “Those isotopes could be rare-earth elements of interest or special nuclear materials. To be able to definitively say, ‘Yes, there's highly enriched uranium in this object' and be able to characterize how much is present would be a significant leap forward over our current capabilities.” DARPA is seeking expertise in a range of technologies on the GRIT program including advanced accelerator technology, high-energy laser systems, novel control systems, and new x-ray and gamma ray detector technology.

GRIT's focus on new, compact photon sources for inspection complements DARPA's Intense and Compact Neutron Sources (ICONS) program, which is developing compact neutron sources. The two technologies would work in tandem, yielding a very robust inspection capability.
