CACI Awarded $24 Million Contract With Pacific Air Forces Air and Space Operations Center

Company to Provide Mission Planning and Command and Control Services

Arlington, VA, January 22, 2007 - CACI International Inc (NYSE:CAI) announced today that it has been awarded a $24 million, five-year prime contract (one base year, with four option years) by the Pacific Air Forces (PACAF) 15^th Contracting Squadron. The award continues the company's six-year relationship providing command and control services and mission planning support for this client. Under the terms of the contract, CACI will support the PACAF 13^th Air Force's newly established Air and Space Operations Center's Air Mobility Division (formerly the Air Mobility Operations Control Center). The center coordinates Air Force command and control functions around the world, over multiple areas of operation. This contract win expands the size and scope of CACI's PACAF work and supports CACI's command and control and logistics areas of business.

The selection of CACI to continue providing a fully functioning and integrated command and control capability within one of the U.S. Armed Forces represents not only significant cost savings for the Air Force but serves as a business model for civil-military cooperative enterprises. The CACI-Air Force partnership delivers increased efficiency and long-term continuity of personnel in helping the Air Force meet its vital goals.

CACI and its teammates will provide PACAF with a wide range of command and control support services, from program management and information technology support, to serving as a "virtual crewmember" to the units assigned to PACAF. The provision of these services is a powerful force multiplier, reducing the number of hours that flight crews must dedicate to flight planning preparation and allowing them to focus more on their strategic combat and support missions throughout the Pacific region.

CACI President of U.S. Operations Paul Cofoni said, "CACI offers proven logistics expertise and a demonstrated track record of successful support for the U.S. Air Force and large, mission support contracts. Our CACI team provides a complete range of innovative and high-value solutions that will increase Air Force capabilities and ensure PACAF's ability to support its operational missions."

According to Dr. J.P. (Jack) London, CACI Chairman, President, and CEO, "CACI's ongoing partnership with the U.S. Air Force continues to expand with our selection to provide service through this important contract. The award reinforces our qualifications as a Tier 1 defense services provider and positions us to maintain our valuable service as a national asset to our Air Force clients, helping them sustain high levels of readiness to support our nation's security priorities."
