OVERVIEW: The AN/TPY-2 aka Forward Based X-Band Transportable (FBX-T) is a mobile, long-range, very high altitude, high resolution, phased array missile defense radar operating in the X-band. 

DETAILS: The AN/TPY-2 is a missile defense radar that can detect, classify and track ballistic missiles. The radar can be deployed in two different modes. In forward-based mode, the radar is positioned near hostile territory, and acquires ballistic missiles shortly after launch while in the boost phase of flight. 

When the AN/TPY-2 radar is deployed in terminal mode, the radar’s job is to detect, acquire, track and discriminate ballistic missiles in the terminal (descent) phase of flight. The terminal-mode AN/TPY-2 also leads the Terminal High Altitude Area Defense ballistic missile defense system by guiding the THAAD missile to intercept a threat.

Specifications:

Frequency			8.55–10 GHz   (I band (NATO),  X Band (IEEE))
Power output: 			unknown (average); unknown (peak)
PRF:				unknown pps
Range Resolution:		unknown
On/Off time: 			unknown min. 
Deploy/Stow time: 		N/A min
Maximum Range:			1000 km (instrumented)
			
  
NOTES:    Air transportable. The TPY-2 radar is primary sensor for the THAAD system.  It is estimated that switching between forward based and terminal modes will take several hours to make the necessary software changes.
