OVERVIEW: The GM 403 is a mobile, 3-D long-range AESA radar for Air Defense operating in the E/F (NATO) "S" (IEEE) Band.  

DETAILS: The GM 400 family includes the GM 403 and the GM 406, and are intended to track a wide range of targets including  UAVs and TBMs, as well as high performance aircraft from very high to very low altitude and providing an excellent wide-area air coverage. 

The GM 403 is the mobile version of the system, while the related GM 406 is intended to be deployed to fixed sites.  The GM 406 has a more powerful trasmitter, increasing it range by 20 percent.

The GM 403 can also be associated with different secondary radars that provide air traffic control capabilities, and that can also integrate Tactical Ballistic Missiles detection and tracking capabilities. The system can be remotely operated and integrated into a networked AD system.
