Raytheon Integrated Defense Systems of Tewksbury, Mass., completed upgrades to a radar system that will be used for testing the Patriot air and missile defense system that will be delivered to the United Arab Emirates, according to a July 22 Raytheon press release.

Raytheon in 2008 was awarded a contract through a foreign military sale worth as much as $3.3 billion to deliver Patriot anti-missile batteries to the United Arab Emirates. The U.S. Army loaned a Patriot radar system to Raytheon for testing, and the radar was upgraded to the Patriot Advanced Capability-3 configuration, the press release said.

Raytheon is on schedule to begin delivering Patriot hardware to the United Arab Emirates in 2012, company spokeswoman Roopa Bhide said. She would not say how many Patriot fire units Raytheon is under contract to deliver. The United Arab Emirates will be the 12th nation to use the Patriot system.
