The Ground Master 400 is a mobile radar system manufactured by ThalesRaytheonSystems.[1] GM 400 is a fully digital 3D active electronically scanned array long-range air defense radar, offering detection from very high to very low altitudes. It tracks a wide range of targets from highly maneuverable tactical aircraft flying below several hundred feet to the unconventional small radar crossection devices, such as UAVs or cruise missiles

The system can be set up by a four-man crew in 30 minutes and can be remotely operated. The system fits in a 20-foot shipping container and weighs less than ten tons. The system can be rapidly deployed mounted on a 6x6 or 8x8 tactical truck and can be transported by a single C-130 aircraft or a helicopter.[2]

The GM 400 has been selected to protect the European Space Agency's Guiana Space Centre. The system was to be operational by the end of 2012.[3]
