British tech firm Roke is shaking up electronic warfare (EW) with its EM-Vis Deceive — a compact, lightweight system that can be carried by troops to jam enemy signals and disrupt drones in the field.
Weighing less than 10 kilograms (22 pounds), the system is built with a modular open architecture, meaning it can easily evolve to meet shifting operational needs.
It is also designed to integrate seamlessly with both existing and future EW and command systems, keeping everything connected and up-to-date.
Additionally, the tool is simple enough for troops to operate with minimal training, an important factor in combat situations where time is of the essence.
Built for Tough Missions
Despite its compact size — just 30 centimeters (11.8 inches) in all directions — the EM-Vis Deceive is built for demanding environments.
It runs on a 36-volt internal DC battery and uses two 150-watt power supplies to keep things running smoothly.
The system is also designed to operate in extreme conditions, from -32 to 55 degrees Celsius (-25.6 to 131 degrees Fahrenheit).

With a 100-megahertz radio frequency bandwidth, the EM-Vis Deceive can handle a wide array of threats, including enemy drones, communications systems, and other signal-based technologies.
A New Era for Electronic Warfare
Paul MacGregor, managing director at Roke, described the EM-Vis Deceive as a “major turning point” in EW.
Traditional systems are often slow to upgrade, costly, and hard to adapt, which can put soldiers at a disadvantage when the stakes are high.
“What happens if a new enemy drone model appears that uses different frequencies? A new custom build would have to be designed, tested and deployed — it could take months or even years,” he argued.
“EM-Vis Deceive changes all of that, it can be quickly upgraded, software updates can be pushed faster, and it can easily communicate with other systems.”
