US Army releases Sentinel radar upgrade RfP
The US Army is pushing ahead with upgrades to its fielded Sentinel A3 radar systems as it looks to address growing threats on the battlefield, including from UAVs and cruise missiles.
This intensifying threat, especially small and slow UAVs and fast cruise missiles with reduced signatures, has fuelled the army’s efforts to enhance the capabilities of its current AN/MPQ-64 Sentinel A3 radar with modern antenna technology.
The upgraded radar, designated the Sentinel A4, will also improve the army’s ability to counter manned fixed wing and rotary targets, as well as offer capabilities against future rocket, artillery and mortar (RAM) threats.
