Raytheon to continue AN/TPY-2 GaN work
Raytheon will continue work to add gallium nitride (GaN) semiconductor technology to the AN/TPY-2 radar under a $10 million contract modification announced on 6 April.
The work includes the development of hardware and software that will add GaN, which increases the radar's range, search capabilities and enables the system to better discriminate between threats and non-threats.
GaN will also increase the system's overall reliability while maintaining production and operational costs.
The AN/TPY-2 is a transportable, land-based ballistic missile defence radar that operates in two modes: forward-based mode - the radar is positioned near hostile territory, and detects, tracks and discriminates ballistic missiles shortly after they are launched; and terminal mode - the radar detects, acquires, tracks and discriminates ballistic missiles as they descend to their target.
The terminal mode AN/TPY-2 is the fire control radar for the Terminal High Altitude Area Defense ballistic missile defence system, by guiding the THAAD missile to intercept a threat.
Dave Gulla, vice president of the Integrated Defense Systems Mission Systems and Sensors business area, said: 'Adding GaN technology modernises the system so it can defeat all classes of ballistic missiles in extreme operational environments.'
