[1] GM400 is a fully digital active electronically scanned array long-range air defense 3D 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 cross section devices, such as UAVs or cruise missiles.

While there is no publicly available information on the cost of the GM406 model, it is estimated that the price of a GM403 radar is around $30,000,000, excluding any additional modifications that may be requested by buyers.

[4] In 2021, Thales introduced a new version, GM400α, with 5 times more processing power, extended range from 470 to 515 km and upcoming advanced artificial intelligence algorithms.

[5][6] These systems are part of the Ground Master family of radars (alongside the medium range GM200 and GM200 MM/A and MM/C as well as the short-range GM60 and its variants) and have been purchased by many countries.
