Rafael unveils Storm Shield to protect drones in contested environments

Rafael Advanced Defense Systems has unveiled Storm Shield, a compact electronic warfare (EW) suite designed to enhance the survivability of unmanned aerial vehicles (UAVs) in contested environments. Revealed at the AOC Electronic Warfare Conference in Helsinki, the system aims to provide drones with protection previously reserved for manned aircraft, particularly when operating within anti-access/area-denial (A2/AD) zones.

Drones have become increasingly capable in sensors, endurance, and autonomy, but they remain vulnerable to modern air-defense systems. As radar technology, passive detection, and electronic countermeasures advance, unprotected drones face significant risks, especially as they are tasked with greater operational responsibilities. Recent operations, such as Operation Roaring Lion, saw several American and Israeli drones downed by Iranian systems, with reports indicating significant losses for both nations, including MQ-9 Reapers costing approximately $30 million each.

Storm Shield is a lightweight, fully autonomous EW suite that continuously monitors the electromagnetic spectrum. It detects and analyzes hostile emissions, then employs tailored deception techniques. The system offers 360-degree coverage, ensuring protection regardless of the UAV's orientation or maneuvers, which is crucial for dynamic intelligence, surveillance, reconnaissance (ISR), or strike missions. Its core technology includes an AESA-based transmitter and Digital RF Memory (DRFM), similar to Rafael's larger EW systems, but miniaturized for UAVs.

The system's modular design and programmable software allow for integration across various UAV classes and mission-specific configurations. Its wide frequency coverage and direction-finding capabilities help address a broad spectrum of radar threats and enhance situational awareness. By operating autonomously, Storm Shield reduces operator workload and enables faster threat responses than human-in-the-loop systems.
