An amendment updates the salient characteristics and combination

A Q&A was published on 10 September 2026 for an updated requirement involving Echodyne EchoShield radars. The EchoShield is a software-defined, cognitive 4D pulse-Doppler Ku-band radar using Echodyne’s MESA technology, offering low SWaP, a 130° azimuth by 90° elevation field of view, less than 0.5° angular tracking accuracy, MIL-STD-810H ruggedization, and IP67 rating. It can track over 1,000 objects simultaneously and output high-precision data to direct optical sensors and mitigation effectors. The system supports counter-UAS, ground dismount and vehicle tracking, coastal perimeter security, and on-the-move mobile operations, with customization via software waveforms. The 57 RQS requests acquisition of four EchoShield radars, four EchoShield software uprates and technical support, and the Echodyne rapid deployment kit.

The EchoShield is a low-SWaP, software-defined 4D pulse-Doppler radar operating in Ku-band, using Echodyne's proprietary Metamaterials Electronically Steerable Antenna (MESA) technology. It provides a 130° azimuth by 90° elevation field of view, sub-0.5° angular tracking accuracy, and can track over 1,000 objects simultaneously while outputting high-precision data to sensors and effectors. The ruggedized unit meets MIL-STD-810H and IP67 standards, and its customizable waveforms enable missions such as counter-UAS, ground dismount/vehicle tracking, coastal perimeter security, and on-the-move operations. The 57 RQS requests acquisition of four EchoShield radars, four units of software uprates and technical support, and the EchoShield rapid deployment kit.
