DRS Technologies, Inc. (NYSE: DRS) announced today that it has been awarded three new contracts with a combined valued of approximately $13.2 million to provide digital signal processors, rugged computers and assemblies for several ground and airborne surveillance applications. Work for these awards will be performed by the company's DRS Tactical Systems unit in Palm Bay, Florida, and DRS Tactical Systems (West) unit in Colorado Springs, Colorado. "DRS is pleased to continue its role as a key provider of airborne and ground force surveillance systems," said Steven T. Schorer, president of DRS's C4I Group. "We remain a leading supplier of high-performance rugged computers, processors and assemblies for a variety of Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance (C4ISR) applications, employing the most reliable and effective surveillance technology available." P-BISA Digitization Processor Units The first award was a new contract from Alvis Vickers Ltd., a subsidiary of Alvis plc. (LSE: ALV), located in Newcastle Upon Tyne, United Kingdom. For this award, DRS will manufacture and deliver Platform Battlefield Information System Application (P-BISA) Digitization Processor Units (PDPUs) to be installed on Challenger 2 Main Battle Tanks. Product deliveries are expected to continue through January 2006. P-BISA is part of the Digitization of the Battlespace (Land) Program that provides a battlefield management system for Challenger 2 Main Battle Tanks. These PDPUs will provide a firewall between the real time high-speed weapon system of the Challenger 2 and the near real-time world of the BOWMAN program. Man-portable Surveillance and Target Acquisition Radar Systems DRS also received new orders from Systems & Electronics Inc., an Engineered Support Systems (NYSE: EASI) company, located in St. Louis, Missouri. For this award, DRS will supply rugged computers to support the Man-portable Surveillance and Target Acquisition Radar (MSTAR) system, to be used by an allied country. Product deliveries are expected to begin in March and continue through August of this year. The AN/PPS-5C MSTAR system is a versatile, low power, ground surveillance radar system that detects, locates and classifies moving ground targets. It can be mounted on wheeled and tracked vehicles or operated remotely. MSTAR provides wide-area surveillance coverage at day and night or during adverse weather conditions, and has a very low probability of intercept (LPI). Its effectiveness has been demonstrated in both international combat and peacekeeping missions during the last ten years. RC-135 Circuit Card Assemblies DRS received a third award from the Integrated Systems division of L-3 Communications Corporation (NYSE: LLL), located in Greenville, Texas. For this award, DRS will fabricate, assemble, test and deliver high-performance, Application-Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs) and high bandwidth input/output for processing multiple channels of signal intelligence data in real time for a recent enhancement program to the U.S. Air Force's RC-135 Rivet Joint aircraft. A single Combined Address generator and FFT (Fast Fourier Transform) Engine (CAFE) circuit card assembly (CCA) provides the customer with sufficient processing power to replace multiple existing processor cards, demonstrating the clear advantages that optimized, high-performance embedded computing architectures have over generic processing boards. Deliveries are expected to be completed by April. RC-135 surveillance aircraft are equipped with an extensive array of sophisticated intelligence gathering equipment enabling military specialists to monitor the electronic activity of adversaries. The DRS-produced CCAs will help to increase performance and better provide indications about the location and intentions of enemy forces, while reducing size, weight and power consumption of the deployed system. DRS is a leading supplier of high-performance tactical computer systems and assemblies for the digitization of the battlefield, used in support of U.S. and international ground force modernization and C4ISR initiatives for land, sea and air operations.
