CACI Awarded $38 Million Task Order to Support Software Acquisition and Full Lifecycle Management for U.S. Army

New Work in C4ISR Arena Enhances Command and Control Capabilities of Army Battle Command Software Systems

Arlington, VA, May 14, 2009 - CACI International Inc (NYSE:CACI) announced today that it has been awarded a new task order of $38 million, under the U.S. Army's Strategic Services Sourcing (S3) contract vehicle. The award, for one base year and two option years, supports the Army's Communications-Electronics Command (CECOM) Life Cycle Management Command (LCMC), Software Engineering Center (SEC), based in Ft. Monmouth, NJ. This new work will focus on support software acquisition and full lifecycle management to enhance the C4ISR (command, control, communications, computers, intelligence, surveillance and reconnaissance) capabilities of current and future Army Battle Command System (ABCS), with specific emphasis on command and control.

The SEC serves as the software technical organization in the evaluation, insertion, and integration of advanced software technology, especially that within the C4ISR domain. "Advanced" refers to the evaluation and application of emerging software technology and to new Army initiatives and Army systems. In addition, a critical responsibility of the Center is to oversee the acquisition of high quality software to ensure that it has been correctly developed and documented and will be supportable during post production.

CACI's C4ISR functional core competency team will help the SEC to architect, design, develop, code, integrate, test, and support the systems, software, databases, and components being acquired. These support the ABCS with system and software acquisition for command and control. All software engineering efforts will be conducted in conformance with the SEC's processes under the Software Engineering Institute (SEI) CMMI Development model. The goal is to provide agile support to enable rapid response to changing user needs during development, while concurrently improving overall quality and efficiency. CACI remains one of the leading prime contractors in the value of task orders awarded on the S3 contract vehicle, which supports many Ft. Monmouth activities.

According to Bill Fairl, President of U.S. Operations, "We're very pleased with this new work from the Software Engineering Center. We appreciate the opportunity given to us to provide this key support to the SEC and ultimately to the ABCS. The award presents a strategic opportunity to further expand the software engineering activities we perform for the Army."

CACI President and CEO Paul Cofoni said, "It is gratifying to all of us at CACI that we are able to provide the expertise and the wide-ranging experience to support the Army and give warfighters the high-technology tools they need to effectively complete their missions. This effort meshes perfectly with CACI's goal of using all of our resources and capabilities to help our nation counter global terrorism."
