The Eviden-developed ARPEGE surface-to-air RADAR threat simulation system deployed during a NATO Air Force training exercise

Based on Mobile Radar Threat Simulator (MRTS) solutions, the ARPEGE radar threat simulator was central to the NATO Tactical Leadership Program exercise conducted in November at Los Llanos Air Base in Spain

Aix-en-Provence, France – February 17, 2026 – Eviden, the Atos Group product brand leading in mission-critical systems through its Avantix business specializing in electronic warfare, is proud to see the RADAR surface-to-air threat simulation system ARPEGE deployed during a Tactical Leadership Program (TLP) exercise of NATO. The operation took place in November at the Los Llanos air base near Albacete in Spain, where TLP training programs are implemented. These training programs provide fighter pilots with highly realistic simulated environments, designed to replicate real-world operational conditions.

This project illustrates Eviden’s commitment to providing solutions tailored to the operational needs of NATO’s armed forces in high-intensity environments.

Designed by Avantix, the ARPEGE system has been in operation since 2022, with the French Electronic Warfare Polygon component[1] and is actively used at NATO’s Los Llanos training air base. The ARPEGE system consists of a central command post and remote light vehicles, equipped with radar signal generators and tracking antennas. Together, they enable the simulation of radar threats, illuminating aircraft in flight. During training flights, these simulated radar emissions replicate real-world threat conditions, triggering the aircraft’s self-protection systems. Fighter pilots are assessed based on their responses, including evasive maneuvers, implementation of countermeasures such as decoying or jamming, or the execution of simulated air-to-ground attacks.
