Raytheon [RTN] has been awarded a $17.2 million Foreign Military Sales contract modification to deliver capability upgrades for South Korea’s Patriot Air and Missile Defense System.

With emphasis on upgrading the global Patriot fleet, Raytheon will deliver prime-power equipment as an alternative power source for Patriot system operations and will deliver communications equipment to enhance Patriot interoperability with air defense command centers.

This contract from the U.S. Army Aviation and Missile Command, Redstone Arsenal, Ala., augments Raytheon’s ongoing efforts as systems integrator for South Korea’s Patriot SAM-X program. To date, Raytheon has been awarded more than $280 million in contracts to support the Patriot SAM-X program.

“This is an opportunity to further our working relationship with the South Korean industry,” said Sanjay Kapoor, vice president for Patriot Programs at Raytheon Integrated Defense Systems (IDS). “Raytheon’s major subcontract partner in South Korea, EHWA Technologies Information, has a robust and proven portfolio of products in power systems for the Republic of Korea Air Force and will be a key partner for these improvements.”
