US Army upgrades Stryker armored vehicles with EchoShield radar for drone threat detection.
According to information published by the U.S. Army Europe and Africa Innovation Directorate on June 20, 2025, the United States Army tested the integration of the EchoShield cognitive radar on an M1126 Stryker Infantry Carrier Vehicle during Project Flytrap, a tactical counter-unmanned aerial systems (C-UAS) training event held at the Joint Multinational Readiness Center in Hohenfels, Germany. Soldiers from the 3rd Squadron, 2nd Cavalry Regiment used the radar system to detect and track aerial threats, providing real-time positional data to mobile end-user devices, enhancing situational awareness in operational scenarios.

EchoShield, developed by the U.S. company Echodyne, is a cognitive 4D radar system utilizing advanced pulse-Doppler technology and operating within the Ku-band (15.4–16.6 GHz). This software-defined radar features a wide field of view (130° azimuth x 90° elevation) and industry-leading angular accuracy of less than 0.5° in both azimuth and elevation. It is capable of simultaneously tracking hundreds of airborne objects, and its high-speed data output can cue optical sensors, effectors, and integrated command-and-control networks.
EchoShield supports various mission profiles, including C-UAS operations at low altitudes, dismounted perimeter surveillance with a range exceeding 8 km for personnel and 11 km for vehicles, and coastal or airspace monitoring. Its low Size, Weight, and Power (SWaP) specifications—measuring 42.5 x 33 x 18 cm and weighing 17.8 kg—make it ideal for vehicle-mounted applications like the Stryker. The radar consumes less than 250W in operation, enabling flexible and sustained deployment in demanding environments.
The platform chosen for this integration was the M1126 Stryker Infantry Carrier Vehicle (ICV), a key component of the U.S. Army’s Stryker Brigade Combat Teams (SBCTs). Developed by General Dynamics Land Systems, the Stryker is a wheeled, eight-wheeled armored vehicle designed for rapid strategic and operational deployment. Powered by a 350 hp Caterpillar C7 engine, it reaches speeds of 62 mph and offers a range of 300 miles. The ICV variant carries a crew of two and a nine-soldier infantry squad, with primary armament options including an M2.50-caliber machine gun or a 40mm MK19 grenade launcher mounted on a Protector Remote Weapon Station. Its modular armor can be upgraded to protect against RPGs and artillery fragments, and the vehicle features C4ISR integration for network-centric operations.
First fielded in 2002 and named in honor of Medal of Honor recipients Pfc. Stuart S. Stryker and Spc. Robert F. Stryker, the Stryker family comprises multiple variants sharing a common chassis. The ICV tested during Project Flytrap reflects the U.S. Army’s efforts to modernize its intermediate forces with technology that bridges the capabilities gap between light infantry and heavy armored units. The successful deployment of EchoShield highlights the platform’s adaptability to integrate next-generation radar systems, improving the Army’s ability to detect, classify, and respond to aerial threats in complex operational environments.
The evaluation of EchoShield during Project Flytrap reinforces the U.S. Army’s commitment to equipping its forces with advanced sensor technologies tailored for contemporary multi-domain challenges.
