$6.5 Million Addition to Existing JSIMS SIGINT Simulation Contract

BTG, Inc. (Nasdaq: BTGI), an information systems and technical services company, was awarded a $6.5 million addition to its existing Joint Simulation System Signals Intelligence Simulation (J-SIGSIM) contract with the National Security Agency (NSA). The contract is to build the Security Common Component (SCC) for the Joint Simulation System (JSIMS) Alliance. JSIMS will provide the next generation of joint military training simulations and is being supported in development by the U.S. armed services, NSA, the National Reconnaissance Office (NRO), the Defense Intelligence Agency (DIA), and a variety of specialized offices and agencies. BTG has been a member of the JSIMS Alliance since 1997 through its work for the JSIMS Program Office, the U.S. Army, NSA, NRO and DIA. JSIGSIM is the largest single BTG effort in JSIMS, with estimated revenue to the company of approximately $28 million over the five-year term of the contract.

The purpose of the SCC program is to provide a common security framework to be used throughout the JSIMS Alliance. In supporting future training and exercise requirements, JSIMS will utilize various levels of classified data, including ultimately unclassified information that can be shared with U.S. allies. SCC will provide the initial capability to support this requirement by making it possible to protect data at two classification levels necessary for U.S. training. Currently scheduled for development through April 2002, SCC will provide the following capabilities: the JSIMS Security Workstation will provide common security administrative services for two levels of JSIMS security enclaves; the JSIMS Up-Guard will allow for the transfer of information from the lower to the upper enclaves; and the JSIMS Out-Guard will allow the transfer of reports from intelligence simulations to operational systems used by the intended training audience.

BTG Vice President Kevin Wilshere, director of the company's Modeling and Simulation practice, said BTG is very pleased to support the SCC and larger J-SIGSIM efforts: "J-SIGSIM has been a wonderful success story. This is a vital effort to provide improved representation of signals intelligence in the next generation of training simulations. The decision to award the Security Common Component task to BTG reflects on the Government's confidence in the J-SIGSIM Team's performance that has led to three consecutive 100% award fee evaluations. We feel both honored and privileged by this level of customer support, and will demonstrate through continued superior performance that it is justified."
