Navy surface ships protect against ballistic missile launch threats and cruise missile attacks to swarming boats and unmanned aerial vehicles (UAVs). SI2’s ultra-wideband, high-power multi-beam electronically steered array (ESA) provides a new capability for shipboard systems to counter existing and evolving threats. The ESA operates in transmit and receive and produces multiple independent beams over a full horizon to zenith and 360 degrees azimuth field of view. The ESA is suitable for shipboard electronic surveillance / electronic warfare operations, and provides a smaller footprint and more agile response than current systems. SI2’s proven array technology is scalable in size, form factor, and operating frequency. SI2 designs and manufactures antennas and arrays for military and space applications. We seek prime contracts to integrate the ESA into their systems.
