The radars -- as well as training, spares and logistics support -- will be delivered beginning in 2015 under a contract with an undisclosed value.
"With this award, we continue our 25 years of support of the Royal Thai Air Force and the national security infrastructure of Thailand," said Robert Royer, vice president of Northrop Grumman's International Systems business unit. "Highly mobile and proven in a wide range of environmental conditions, the AN/TPS-78 will give the Royal Thai Air Force a powerful new capability for monitoring its national airspace."
The AN/TPS-78 is a long-range, S-band radar used by the U.S. Air Force and others. It features state-of-the-art high-power transistor technology and is adept at detecting small targets in areas of difficult land and sea clutter.
Northrop Grumman did not disclose the number of systems it is supplying Thailand.
