radar called the SMART-L-EWC (Early Warning Capability) Radar. It has a greater search radius: a tracking range of 2000 km for ballistic missiles and 480 km for air targets. SMART-L EWC is a programmable AESA radar that is characterized by full flexibility. Additional capabilities can be introduced during its lifetime according to customer needs. This makes the radar future-proof in case of evolving requirements.
