Under the award from the U.S. Missile Defense Agency and the Air Force, the new system will also be able to provide targeting data for destroying incoming ballistic missiles.
Raytheon drew on its seven decades of experience designing, developing, building and operating radars to offer the government a cost-effective solution that will help keep America and its allies safe from enemy missiles," said Dave Gulla, vice president of Global Integrated Sensors for Raytheon's Integrated Defense Systems business.
"Our experience as the designer and developer of the proven EWR and our experience upgrading EWR systems in California, the U.K. and Greenland, enable us to provide the government a low-risk solution at a very competitive price."
The phased-array EWR designated for upgrade is in Alaska.
Raytheon said it expects to complete the project by the end of 2017. Other deployed EWR systems will continue operations during the upgrade.
