US Army test shows Coyote Block 3 can knock down drone swarms with an electromagnetic weapon
The U.S. Army has demonstrated a new Coyote interceptor that can disable multiple drones with an electromagnetic attack. The test points to a cheaper way to defeat swarm assaults that can quickly drain stocks of conventional interceptors.
The problem is simple. Small drones are cheap, numerous and easy to launch in coordinated waves. Traditional defenses are not. Most rely on explosive or kinetic interceptors built around a one-shot-one-kill model. That approach becomes costly fast, especially when defenders face saturation attacks from several directions at once. It also creates a magazine-depth problem. A force can run out of ready rounds long before it runs out of targets.
The recent Army event at Yuma Proving Ground in Arizona was designed to stress that weakness. The demonstration used the Low, slow, small-unmanned aircraft Integrated Defeat System, or LIDS, against about 10 incoming drones approaching from different directions. The scenario tested the system’s Ku-band radio frequency sensor, its tracking performance, and the ability of the Coyote Block 3 to identify threats, lock on, make engagement decisions and carry out an intercept under saturation conditions. Unlike earlier versions built to destroy targets through impact or explosive force, the new variant swaps the warhead for an energy-based payload.
Coyote has evolved significantly across three major versions. The original model was an electric, propeller-driven aircraft with pop-out wings intended for reconnaissance. Block 2 shifted to a turbine-powered design with four control fins and turned the platform into a drone-killing interceptor missile. Block 3 keeps that airframe and performance but replaces the kinetic kill mechanism with what appears to be an electromagnetic weapon. The exact system has not been disclosed. It is likely either a high-power microwave payload or an advanced electronic warfare package. A microwave burst could disable a drone by overwhelming its electronics. An electronic warfare system could jam or disrupt signals badly enough to make the aircraft lose control or fail in flight. The significance is not just the effect. It is the size. Shrinking such a weapon enough to fit inside a small, fast interceptor creates a close-in airborne counter-drone tool that can engage targets more efficiently than a larger stand-off system. The platform is reported to have the range, speed and altitude needed to engage Group 2 and Group 3 drones. It can also function as a node in the Forward Area Air Defense Command and Control network. Just as important, it can link with other Coyotes so multiple interceptors can divide targets and coordinate attacks autonomously, reducing the need for continuous human control and allowing several threats to be tackled at once.
Block 3 also changes the economics of the mission. Rather than being expended after each engagement, the aircraft is designed to be recovered at the end of a sortie using a net capture system. That means operators do not have to sacrifice the airframe and sensor package every time they respond to a drone attack. The main recurring costs become fuel, battery refurbishment and maintenance. In a threat environment defined by low-cost unmanned aircraft and increasingly complex swarm tactics, that matters. A reusable interceptor with an electromagnetic effect offers a way to preserve expensive missile inventories, sustain defenses longer during repeated attacks and lower the cost of protecting bases, formations and critical infrastructure.
