PELHAM, N.H. - Raytheon Company's newest integrated air and missile defense radar has been busy since its debut at the 2016 Winter AUSA tradeshow. The gallium nitride-powered Active Electronically Scanned Array proposed upgrade to the Patriot Air and Missile Defense has surpassed more than 1,000 hours of operation in just over a year, which is half the time of a typical testing program.

"We achieved this milestone so quickly because of our successful experience developing and maturing GaN for programs like the U.S. Navy's Air and Missile Defense Radar," said Doug Burgess, director of AESA programs at Raytheon's Integrated Defense Systems business. "We're ready to take the next step and get this radar into the hands of our customers."

During the course of the 1,000 hours, Raytheon's GaN-based AESA prototype radar routinely demonstrated 360-degree capability by working together with a second GaN-based AESA antenna that was pointed in a different direction. As targets flew out of one array's field of view and into another, the two arrays seamlessly passed information back and forth, tracking the target continuously. The main array also detected and tracked tactically maneuvering fighter jets and thousands of other aircraft.

"Raytheon's GaN technology is backed by 19 years of research and $300 million in investment, while our competitors are either new to the market or primarily build GaN for commercial applications," said Ralph Acaba vice president of Integrated Air and Missile Defense at Raytheon's Integrated Defense Systems business. "When national security is on the line you want highly reliable, proven technology that is certified by the U.S. Department of Defense for use in military radars."

Raytheon's GaN-based AESA radar will work with the Integrated Air and Missile Defense Battle Command System and other open architectures. It maintains compatibility with the current Patriot Engagement Control Station and full interoperability with NATO systems.

A number of current and expected future Patriot Air and Missile Defense System partner nations in Europe and Asia have expressed interest in acquiring GaN-based AESA. Poland submitted a Letter of Request for GaN-based AESA Patriot on March 31. Raytheon's GaN-based AESA technology also meets Germany's requirements for the German Taktisches Luftverteidigungssystem, or TLVS, tactical air and missile defense system.

WHEN WILL U.S. BEGIN TO TAKE THE DEMAND FOR MORE BANDWIDTH SERIOUSLY?

NEWTOWN, Conn. - The Joint Spectrum Center (JSC), which is a division of Defense Spectrum Organization (DSO), designs, develops, and maintains U.S. Department of Defense (DoD) automated spectrum management systems, evaluation tools, and databases. The databases are the prime sources of information for DoD use of the electromagnetic (EM) spectrum. The JSC provides technical measurement and analysis in support of DoD spectrum policy decisions to ensure the development, acquisition, and operational deployment of systems are compatible with other spectrum dependent systems operating within the same EM environment (EME).

Additional efforts by the JSC focus on improving future warfighter EM spectrum utilization through technological innovation, and influencing research and development emerging technology efforts. Improved spectrum support includes the Global Electromagnetic Spectrum Information System (GEMSIS), a net centric capability that will provide commanders with an increased common picture of spectrum situational awareness of friendly and hostile forces while transparently deconflicting competing mission requirements for spectrum use. This capability will enable the transformation from the current preplanned and static assignment strategy into autonomous and adaptive spectrum operations.

Both the defense and civil preparedness sectors and the commercial sector continue to demand additional bandwidth. However, neither Congress nor the DoD seem to be taking this demand seriously, as funding for the JSC is continuously cut in favor of higher priority programs. Funding for the Joint Spectrum Center is expected to decline over the next few years as current projects wrap up. Starting in 2019, however, funding will likely start to increase again as new advancements come into play and development.

WASHINGTON - Northrop Grumman Systems Corp. is being awarded $13.9 million for modification P00003 to a previously awarded firm-fixed-price contract (N00019-16-C-0026) for procurement of additional hardware to integrate Navy large aircraft infrared countermeasures (LAIRCM) on combat aircraft for the Navy and the governments of the U.K. and Australia.

Hardware for this procurement includes weapon replaceable assemblies and support equipment: two 2103 Signal Processors, 23 Guardian Laser Transmitter Assemblies (GLTAs), 23 GLTA shipping containers for the Navy, and 18 Multi-role Electro-optical End-to-End Test Sets for the Navy (14) and the governments of the United Kingdom (two) and Australia (two).

Work is expected to be completed in April 2019. Fiscal 2017 aircraft procurement (Navy, Air Force); working capital fund (Navy); and international partner funds in the amount of $13.9 million are being obligated at time of award, none of which will expire at the end of the current fiscal year. This modification combines purchases for the Navy ($13 million; 94 percent); Air Force ($528,180; 4 percent); and the governments of U.K. ($176,060; 1 percent) and Australia ($176,060; 1 percent). The Naval Air Systems Command, Patuxent River, Maryland, is the contracting activity.
