BEDEX 2026: FN Herstal develops the C-UAS counter-drone system

At BEDEX 2026 (Brussels European Defence Exhibition), held March 12–14 in Brussels, FN Herstal, operating within the Defense and Security division of the Belgian FN Browning Group, presented elements of a developing C-UAS (Counter-Unmanned Aerial Systems) counter-drone system.

The comprehensive solution consists of three mutually complementary components:

• a medium-sized remote weapon station, the FN deFNder Medium, equipped with the 30 mm Northrop Grumman M230LF automatic cannon, capable of destroying larger aerial targets at distances of up to 2,000 m;
• the FN Dual Light Multi Weapon Mount (Dual LMWM) firing position, configured with two FN MAG machine guns chambered in 7.62 × 51 mm NATO, designed to engage small drones and multirotor UAVs at ranges from 80 to 400 m, fitted with a holographic sight and a targeting support package including a camera, AI system, and acoustic warning system;
• semi-automatic shotguns equipped with the FN VictoR aiming support system and 12/70 gauge cartridges containing tungsten pellets for engaging small drones, including FPV types, at distances of up to 100 m, or alternatively FN SCAR multi-caliber carbines to extend the engagement range.

The C-UAS concept reflects lessons learned from the ongoing armed conflicts in Ukraine and the Middle East, where small and inexpensive drones have proven capable of threatening armored vehicles, artillery units, logistics hubs, and command posts.

These drones often operate in swarms or appear without warning, forcing soldiers to rely on layered defense systems capable of engaging targets at different ranges and altitudes. FN Herstal’s approach reflects a new doctrine, emphasizing multi-layered kinetic defense rather than reliance on a single weapons system.

To achieve this, sensors and targeting-support systems, as well as image-processing solutions from external suppliers, have been integrated. The system can also be connected to a broader architecture incorporating radars, electro-optical tracking systems, and electronic warfare sensors, complementing the kinetic capabilities.
