Russian Groza-Z3-JM EW system protects vehicle groups via spoofing

Bottom line

KB Radar's Groza-Z3-JM EW system is deployed to protect vehicle groups, using RF jamming and spoofing within a 10km radius to detect and neutralize silent drones.

Why it matters

The Groza-Z3-JM's ability to detect silent drones and spoof controls poses a significant challenge to Ukrainian FPV operators relying on standard datalinks, potentially forcing a return to optical or fiber-optic guidance for critical strikes.

Russian milbloggers report the deployment of KB Radar’s Groza-Z3-JM electronic warfare system. The system is designed to protect groups of vehicles and objects by integrating with radars to detect ‘silent’ drones (those not emitting RF signals) and employing RF jamming and spoofing within a 10km radius. This represents a move towards integrated, area-denial EW rather than point-defense.
