CACI Awarded $36 Million Modeling and Simulation Contract With U.S. Army Night Vision and Electronic Sensors Directorate

Continues CACI Support for Training and Technology Development

Arlington, VA, August 27, 2008 - CACI International Inc (NYSE:CAI), announced today that it has been awarded a $36 million prime contract to support the Modeling and Simulation Division of the U.S. Army's Night Vision and Electronic Sensors Directorate (NVESD). CACI received the competitive three-year contract (two-year base and one-year option) under its Strategic Services Sourcing (S3) contract with the U.S. Army. This is the sixth NVESD award CACI has announced since December 2007, for a total of more than $129 million in awards since that date. This new award increases both the size and scope of CACI's work with NVESD's Modeling and Simulation Division and strengthens CACI's functional core competency in C4ISR (command, control, communications, computers, intelligence, surveillance, and reconnaissance).

NVESD provides the Army with research and development of advanced night vision and other sensor technologies, such as infrared weapon sights, surveillance systems and systems that enhance the soldier's ability to operate at night and during limited visibility conditions. CACI's services to NVESD's Modeling and Simulation Division will support Joint and Army simulation applications that are designed to make military training more realistic and effective while interoperating across all the services.

CACI's role focuses primarily on developing software simulations for NVESD to use in training troops on key C4ISR systems. CACI's team provides advanced, high-resolution 3D graphics, simulations of ground and air vehicles, and terrain mapping and other functions to help contain costs while accelerating the delivery of new capabilities to the warfighter. The company also supports the upgrading of current modeling and simulation software and provides technical support for concept development, systems development, and systems integration and testing. In continuing its NVESD role, CACI assures uninterrupted services delivered by a team with in-depth knowledge of, and familiarity with, NVESD's technical environment and mission requirements.

Said Bill Fairl, CACI President of U.S. Operations, "CACI is proud to continue our support for the U.S. Army's Night Vision and Electronic Sensors Directorate in the technologies our company was founded upon – modeling and simulation. We offer leading-edge solutions and services that ensure timely and effective modeling and simulation support for training and technology development."

According to Paul Cofoni, CACI President and Chief Executive Officer, "As our sustained and growing business with the U.S. Army's Night Vision and Electronic Sensors Directorate shows, CACI continues to expand our support for the nation's greatest needs and requirements. We are proud to play a role in products and services that directly support our warfighters and their ability to complete their missions."
