CACI Awarded Prime $70 Million Contract to Support Military Sealift Command

Expanded System Development Support Services Integrate Logistics and Engineering Processes for Shipboard and Shore-Based Personnel Worldwide

Arlington, VA, August 24, 2009 - CACI International Inc (NYSE:CACI) announced today that it has been awarded a prime $70 million, indefinite delivery/indefinite quantity contract for up to 7-1/2 years to provide integrated logistics and engineering system development support services to the U.S. Navy's Military Sealift Command (MSC). The contract was awarded directly by the MSC and expands both the size and scope of CACI's 19-year relationship with the Command to now include a wide array of engineering systems.

The mission of the MSC is to support the U.S. Navy by delivering supplies and conducting specialized missions all over the world. The Command provides sealift and ocean transportation for all U.S. military services as well as for other government agencies, operating tankers for fuel transport and dry-cargo ships that transport equipment, vehicles, helicopters, ammunition, and supplies.

The new contract award grows CACI's strategic business through its core competencies of logistics and material readiness and business system solutions. The CACI team blends functional and technical expertise in both logistics and engineering systems to integrate and enhance the flow of information for the MSC between shipboard and shore-based personnel. Consistent application of Software Engineering Institute (SEI) CMMI Level 3-compliant processes and ISO 9001:2008 best practices result in efficient systems development and continuous innovation and improvement.

According to Bill Fairl, CACI President of U.S. Operations, "We're very pleased that this award from the Military Sealift Command enables us to expand our long standing support for the Command's logistics needs to now include the engineering component. The outstanding best practice credentials CACI brings to the table provide the MSC with an increased capability to meet its future requirements."

CACI President and CEO Paul Cofoni said, "At CACI, we're very cognizant of the vital services the Military Sealift Command performs for our nation every day, enabling the Navy to project its power wherever it is necessary to counter global terrorism. So we're happy that this contract provides a key component in leveraging logistics and engineering capabilities and integrating systems to deliver more value to such an important customer."
