EL SEGUNDO, Calif., July 12 -- Computer Sciences Corporation (NYSE: CSC) today announced that it has helped successfully transfer two key elements of the U.S. Navy’s Aegis Weapon System to an open architecture computing environment.

As a leading member of the Lockheed Martin team responsible for the accomplishments, CSC helped meet key milestones which will enhance the capabilities and service life of the system. This will allow the Navy to use commercial computing technology and install and upgrade software faster and more cost effectively throughout the life of a ship, aircraft or submarine.

“The Lockheed Martin Open Architecture team is making impressive progress,” said Capt. Richard T. Rushton, the Navy’s chief for the Network Systems and Integration directorate. “The team’s innovative engineering approach and commitment to open architecture indicates we are on track for our upgrade timeline.”

Two engineering trials successfully demonstrated the ability to seamlessly transition software from one environment to the next, highlighting the flexibility of the newly designed programs. The first trial demonstrated the Open Command and Decision system’s ability to perform air and surface defense roles and accept data from different types of sensors under a variety of technical conditions. The second trial demonstrated the SPY Radar Control program’s ability to detect, track and engage targets.

Both systems were built using a typical Open Architecture Computing Environment (OACE) Category 3 infrastructure. OACE is a set of international standards designed to separate computing environments from requirements of custom software, speed the development of new applications and significantly reduce the cost of technology upgrades and refresh. The Navy has chosen OACE Category 3 as the first step in the service’s move to an open computing environment.

“These engineering successes are built on CSC’s blend of leadership in complex combat systems development, commercial enterprisewide open systems and architecture implementation,” said Aaron Fuller, president of CSC’s Defense Mission Engineering and Integration Division. “CSC provides the team with crucial experience needed to advance the Navy’s open architecture vision.”

The team will continue the evolution of the Aegis architecture and computing environments by upgrading the radar control architecture and computing environment for all SPY-1 radar systems, beginning with SPY-1B/D radars. In addition, the team will develop an architecture that will enable the Aegis weapon control and display systems to operate in an open computing environment.
