The US Army has selected Lockheed Martin to build the next generation of AN/MPQ-64 Sentinel air-defence radar systems over incumbent Raytheon.
Under the terms of the deal, valued at USD281 million, Lockheed Martin will spearhead work on the A4 variant of the stand-alone 3D Sentinel radar system, building upon the capabilities aboard the Raytheon-built A3 system currently being fielded by US Army units.
The Sentinel A3 system is an X-Band, Gallium Nitride (GaN)-based system with a scan rate of 30 RPM and a maximum 360-degree detection range of 40 km. Employed with electronic countermeasures, the Sentinel can be deployed with an army ground unit on a towed platform, or operated autonomously from a forward location ahead of a unit's position via wideband fibre-optic datalinks or Single Channel Ground and Airborne Radio System (SINCGARS).
