ROCKWELL COLLINS AWARDED CONTRACT FOR E-6B AVIONICS, MISSION SYSTEMS UPGRADES

Rockwell Collins, a leader in communications and aviation electronics solutions, was awarded a $79 million contract by NAVAIR PMA-271 to provide Block I Modification upgrades for the U.S. Navy's fleet of E-6B aircraft. The program has a potential value to Rockwell Collins of approximately $300 million over 10 years.

The Block 1 modification addresses legacy system integration deficiencies and projected obsolescence issues by providing the E-6B aircraft with an open system architecture for the mission avionics, and upgrading primary mission systems including the Digital Airborne Intercommunication Switching System (DAISS) and Intercommunications System (ICS) (DAISS/ICS), the mission computer set, and the Ultra High Frequency Command, Control and Communication (UHF C3) system. In addition, the electrical power and cooling systems will be modified to improve preflight, post-flight and ground alert operations.

"For almost four decades, Rockwell Collins has supplied the avionics suite for many of the "Take Charge and Move Out" (TACAMO) aircraft, which provide reliable and survivable communications between the President of the United States, Secretary of Defense and the U.S. strategic forces," said Greg Churchill, executive vice president and chief operating officer for Rockwell Collins Government Systems. "We will use our technology and experience to provide an open system solution that addresses immediate needs, while enabling transformational growth in the future. Our solution provides an infrastructure to support moving data on, off and throughout the aircraft even as user bandwidth demands increase in this emerging age of the digital battle-space.

"More importantly, the E-6 Block 1 program provides a template for transforming additional mission aircraft to serve key roles in an emerging network centric world," Churchill added.

Rockwell Collins is fielding open systems architecture solutions that are similar to the open design approach utilized in the computer and telecommunications industries. By applying this approach across product lines in avionics, communications, computer processing and networking, Rockwell Collins can reduce time to market and overall life-cycle costs, as well as improve long-term system viability through designed-in capability for upgrades and growth.

Rockwell Collins (NYSE:COL) is a leader in the design, production and support of communications and aviation electronics solutions for government and commercial customers worldwide.
