Instead of jamming, which floods the airwaves with noise, the ARM‑V transmits low‑power, highly precise fake satellite signals that override the drone’s receiver.

Armored vehicles are facing an escalating threat from drones as battlefields shift toward cheap, precise aerial weapons.
Quadcopters and fixed‑wing UAVs now carry anti‑armor munitions, drop grenades through hatches, or guide artillery with pinpoint accuracy.
In Ukraine, thousands of armored vehicles have been destroyed or disabled by FPV drones alone, and Hezbollah, the Houthis, and Hamas have adopted similar tactics.
Even tanks like the T‑90 and Merkava Mark IV are vulnerable without dedicated counter‑drone protection, making aerial threats a defining challenge for modern armor.
Regulus Cyber’s Ring ARM‑V is an Israeli electronic‑warfare system designed to protect armored vehicles from the rapidly growing threat of hostile drones.
The system is based on the company’s Ring C‑UAS technology, described as the first combat‑proven platform capable of manipulating satellite navigation signals to intercept drones, including multi‑rotor, fixed‑wing, swarm, and “dark” drones.
At its core, the ARM‑V works by spoofing GNSS (Global Navigation Satellite System) signals—the satellite‑based navigation services used by most small drones, including GPS, GLONASS, BeiDou, and Galileo.
Instead of jamming, which floods the airwaves with noise, the ARM‑V transmits low‑power, highly precise fake satellite signals that override the drone’s receiver.
This allows the system to take control of the drone, feed it false coordinates, divert it, freeze it in place, or push it away from the protected vehicle.
Regulus CEO Yonatan Zur explains that the system “takes over the receiver” and can “fly the drone” by giving it fake locations.
The ARM‑V is compact—roughly a one‑foot‑square box with a small antenna—and creates an invisible EW “bubble” around the vehicle.
It offers two operating modes: low‑power, providing about 150 meters of omni‑directional protection and 1,000 meters of top protection, and high‑power, extending to 1,500 meters omni and over 5,000 meters top protection.
Compared to competing counter‑drone systems, which often rely on bulky jammers, multiple antennas, or require a dedicated operator, the ARM‑V is designed specifically for armored vehicles and can be integrated in under a month.
It is also notable for being the first C‑UAS system ever installed inside an operational armored vehicle, according to Regulus.
Regulus states that the ARM‑V has been operational for two years and has already been integrated with armored vehicles as part of a project with a “leading Western army,” though the company has not disclosed which country.
Operational testing on additional platforms began in 2023.
