Thales to upgrade air-defence radar systems

Air-defence company Thales Raytheon Systems has been awarded a $21.8m (£15m) contract by the US Army to upgrade multiple AN/MPQ-64 Sentinel air-defence radar systems, as an option to the existing upgrade contract originally awarded in June 2007.

The contract will upgrade the Sentinel radar transmitters, receivers and exciters, and increase functional capabilities such as data processing and detection range for smaller targets.

Additional capabilities will also help minimise instances of fratricide and accidental counter-missile firing, and facilitate a transition to defence-force mobility.

Upgrade work will be performed in El Paso, Texas, and Fullerton, California.
