August 18, 2007: Thailand is buying an AN/TPS77 radar from the United States. This is a portable military radar that can cover out to 450 kilometers, and up to 100,000 feet. You can set up the phased array (AESA) radar panel in a remote location, and have the radar information, and the status of the radar, monitored elsewhere. The AN/TPS-77 operates, on average, about 11 weeks before needing the attention of any technicians. The AN/TPS-77 will complete Thai air defense system, giving the air force radar coverage over all its borders. The AN/TPS-77 costs about $100 million. The entire system can be moved using three tractor trailers. These trailers can be moved by air as well.
