CACI Awarded $24.5 Million Task Order to Continue Support for U.S. Army Airborne Intelligence

Company's Strategic Services Sourcing Business Exceeds $2 Billion

Arlington, VA, September 15, 2009 - CACI International Inc (NYSE:CACI) announced today that it has been awarded a $24.5 million task order to provide Airborne, Intelligence, Surveillance, and Reconnaissance (AISR) Ground Station Support to the U.S. Army Product Manager Aerial Common Sensor. The contract, for one base year and two option years, was competitively awarded under the Army's Strategic Services Sourcing (S3) contract vehicle. The work increases both the size and scope of CACI's current business supporting AISR, with the total amount of CACI's S3 awards at more than $2 billion.

AISR Ground Station Support provides an intelligence system housed in specially modified aircraft. It collects and processes intelligence data, then transfers this information to ground locations for further processing, analysis, and dissemination. Since its inception during the Cold War, the system has steadily evolved to meet the needs of the Intelligence Community.

Through its core competency in C4ISR (command, control, communications, computers, intelligence, surveillance, and reconnaissance), CACI provides proven program management, engineering and integration, test and evaluation, and logistics support and training. One of the company's key offerings is its "quick-reaction" capability to integrate new intelligence tools and resources that keep the AISR program current and enable field commanders to act rapidly on warfighter threats.

CACI President of U.S. Operations Bill Fairl said, "Our team brings important continuity and expertise to the U.S. Army's essential airborne intelligence efforts. We are pleased to offer our unique insight into AISR technical requirements, critical deadlines, and required skillsets to help the Army deliver accurate and timely intelligence that protects and supports our troops."

According to CACI President and CEO Paul Cofoni, "CACI's Strategic Services Sourcing business with the U.S. Army, at over $2 billion in task order awards, enables us to continue delivering critical client support and high shareholder value. We are proud to provide services and solutions that are innovative and ahead of the curve in supporting missions of the highest importance to our government and our nation."
