Raytheon’s gallium nitride chips meet operational milestone

Gallium nitride (GaN) chips from Raytheon in Tewksbury, Mass., achieved 1,000 hours of reliable operation, moving the technology closer as a standard for next-generation radar. Raytheon engineers have demonstrated the operation of a GaN power amplifier microwave monolithic integrated circuit (MMIC) operating for more than 1,000 hours with no measurable performance degradation. GaN technology provides increased reliability and efficiency, resulting in lower prime power consumption and relaxed cooling requirements, Raytheon officials say. GaN T/R modules provide higher long-pulse radio-frequency (RF) power than that of standard gallium arsenide (GaAs) T/R modules, company officials say. “This milestone enables us to insert GaN next-generation capability into a multitude of air and missile defense programs,” says Pete Franklin, vice president for Raytheon Integrated Defense Systems’ National & Theater Security Programs. “GaN will also give the warfighter significantly more mobility, capability, and reliability on the battlefield. Its ability to run more efficiently than other technologies will help solve many of our customers’ logistical concerns.”

Northrop Grumman demonstrates interoperability between manned and unmanned platforms

Northrop Grumman Corp. in Bethpage, N.Y., demonstrated Joint STARS and E-2 Hawkeye interoperability between manned and unmanned aerial vehicles (UAVs) during a virtual joint military demonstration involving U.S. and coalition forces. The demonstration, Empire Challenge 09 (EC09), was executed by U.S. Joint Forces Command (USJFCOM) and aimed at demonstrating how U.S. and coalition forces can better work together to collect, analyze, and share relevant reconnaissance information. During the month-long exercise, virtual physics-based and operational flight program simulations of multiple Northrop Grumman platforms, including the E-8C Joint Surveillance Target Attack Radar System (Joint STARS) and E-2 Hawkeye Airborne Early Warning and Control (AEW&C) aircraft, worked collaboratively to achieve interoperability between multiple manned and unmanned aircraft via an airborne Web services architecture. One key element to the success of this interoperability was an E-2 Hawkeye developmental test bed, Northrop Grumman officials explain. The test bed is based on the capability of the U.S. Navy’s E-2 Hawkeye mission computing system which enabled it to operate the electro-optical (EO) sensor onboard both manned vehicles and UAVs in response to requests from ground commanders. Using machine-to-machine command interfaces, the E-2 test bed was able to cue each UAV simulator to provide imagery of both static and dynamic ground tracks for target identification. The image request messages were transmitted via machine-to-machine interfaces, replacing the need for voice and manual chat and also resulting in a faster response time. The virtual Joint STARS integrated the Battle Management Command and Control (BMC2) architecture providing constellation management along with UAV control and multi-level security capability sets. The added capabilities enabled the platform to demonstrate an expansion of its current ISR role to include automated UAV image collection and development of target quality solutions to support strike engagements.

Lockheed Martin to support submarine imaging system

The U.S. Navy awarded Lockheed Martin in Manassas, Va., a contract for engineering services and support of the AN/BVY-1 Integrated Submarine Imaging System (ISIS) and for production of related hardware. ISIS revolutionizes Navy submarine surveillance capabilities by integrating digital video and still images from devices on a submarine’s exterior and presenting real-time imagery and analysis on crews’ existing control room tactical displays, Lockheed Martin officials say. “With ISIS, a submarine operator can manipulate a photonics mast with a joystick, while looking at digital video on a computer monitor, and share that video [in real time] with the entire combat team on various displays aboard the vessel,” says Denise Saiki, vice president and general manager of Lockheed Martin’s Undersea Systems business. ISIS also provides submarine operators with additional image enhancement and analysis tools; active and passive range finding control; and recording, storage, and recall options for imagery and associated data.

Lockheed Martin delivers final C-5B Galaxy Transport modified under avionics upgrade program

Lockheed Martin delivered the 50th C-5B Galaxy strategic transport modified under the Avionics Modernization Program (AMP) back to the Air Force. This completes the AMP modifications to the C-5B fleet. Modification of the C-5A fleet continues at Travis AFB and at Dover AFB, Del. Current plans call for the entire 111-aircraft C-5 fleet to receive the AMP modifications. AMP is the first phase of a two-phase modernization effort for the C-5. The AMP modifications replace the earlier analog avionics in the Galaxy with a commercially available, digital avionics suite along with an integrated architecture that allows for upgrades. The entire system is designed to increase safety, ease crew workload, and enhance situational awareness. “AMP takes all the gauges you see in a legacy aircraft and consolidates them,” says Lt. Col. Mike Semo, chief, C-5M Program Integration Office at Dover. “So now, instead of knowing a distance to a certain location, you have a top-down view of where the aircraft is compared to where you’re going. It gives you a lot more situational awareness, which is very important in a combat zone.” A total of 55 C-5 aircraft (50 C-5Bs, two C-5Cs, and three C-5As) have already been through one of the two AMP modification lines.

Northrop Grumman MQ-8B Fire Scout UAV completes RSTA/ISR demonstration

Northrop Grumman’s MQ-8B Fire Scout Vertical Unmanned Aircraft System (VUAS), designated P7, demonstrated its reconnaissance surveillance, and target acquisition/intelligence, surveillance, and reconnaissance (RSTA/ISR) capabilities at Yuma Proving Ground in Yuma, Ariz. This RSTA/ISR demonstration was conducted with the use of a high-magnification electro-optical, infrared (EO/IR) payload, which includes a long-range laser designator and range finder (LR/LD). Full-motion video was relayed down to ground operators in real time over a Tactical Common Data Link (TCDL). After an autonomous launch, Fire Scout demonstrated its ability to find, fix, and track hostile forces during a real-time operational scenario in complex terrain at night. Fire Scout has the capability to support several different RSTA payloads including FLIR System’s BRITE Star II EO/IR/LR/LD, Northrop Grumman’s ASTAMIDS EO/IR/LR/LD (which also provides countermine capabilities), and FLIR System’s Star SAFIRE III EO/IR/LR. Additional payloads can be easily integrated using Fire Scout’s robust open systems modular payload architecture, says a representative. This flexibility also enhances Fire Scout’s ability to support the warfighter. Fire Scout’s RSTA/ISR demonstration highlighted its capability to provide critical real-time RSTA to brigade combat teams (BCT). Fire Scout provides the commander with a view of a selected area across all wavelength spectrums enabling decision-making and integration of soldiers’ actions with supporting BCT fires and effects.
