Tactical mobile electronic warfare (EW) systems FC.K, developed by Ukraine’s First Contact in partnership with Germany’s GSMK, have been codified to NATO standards and received official certification confirming their compliance with Alliance requirements and readiness for deployment in the Armed Forces of Ukraine.
According to Defense Express on August 14, obtaining a NATO codification number grants access to the Alliance’s unified defense infrastructure, which includes dozens of countries and thousands of units.
This ensures interoperability, transparent supply, and effective operation in multinational environments.

The FC.K system is designed to detect and jam remote-control channels of unmanned aerial vehicles, as well as video and telemetry transmission links between drones and their control stations.
While detailed specifications remain classified, the system supports remote operation via a control station, enabling missions to be conducted without the operator being physically near the vehicle.
Currently, the FC.K is mounted on the Kozak-5 armored vehicle, produced by the Ukrainian company Praktika, allowing it to operate in high-risk areas while providing protection for the crew against FPV drones and other threats.
Earlier, the international Electronic Warfare Coalition—launched in April 2024 by Ukraine, Germany, and partner nations—expanded to include Belgium, Sweden, Italy, Turkey, and Estonia, with Sweden joining Germany as co-chair, according to Defense Minister Rustem Umerov on June 5.
