ViaSat Receives F-35 Lightning II U.S. Reprogramming Laboratory Award

ViaSat Inc. (Nasdaq: VSAT) has received a $12 million award from Lockheed Martin Aeronautics Co. for the manufacture, integration, test, and delivery of a Communication, Navigation, and Identification (CNI) Function Stimulator (CFS) for avionics testing of F-35 Lightning II aircraft, also known as the Joint Strike Fighter. This follow-on CNI Stimulator is an integral part of the Verification and Validation Facility (VVF) for the U.S. Reprogramming Laboratory (USRL) at Eglin Air Force Base, Florida. ViaSat delivery of the CFS to Lockheed Martin is scheduled for 2010. The complexity of the avionics systems in state-of-the-art fighter aircraft requires realistic test environments and accurate signal representation. ViaSat RF stimulators provide a true-to-life CNI test environment and reduce the cost of in-flight testing. For more than 10 years ViaSat has been developing and delivering CNI test systems to DoD customers. RF stimulation from ViaSat goes beyond ordinary simulation and computer modeling techniques to actually stimulate the avionics environment with real signals of RF energy, including RF jamming and background signals.
