HELMA-LP Laser System Integrated into Sherpa Scout’s T1 Hornet Turret for Mobile Anti-Drone Defense

At Techterre 2025, a defense technology exhibition focused on operational innovation, the integration of the HELMA-LP laser system onto the T1 Hornet remotely operated turret marked a notable development in decentralized anti-drone warfare. This initiative, led by French defense firms CILAS and Arquus, reflects a broader shift toward modular and mobile counter-UAV solutions, addressing longstanding limitations in centralized air defense systems.

The HELMA-LP system is a portable laser weapon derived from the more powerful HELMA-P platform. While HELMA-P was designed for fixed or naval installations and has been deployed in high-profile events such as the 2024 Paris Olympics, HELMA-LP offers tactical portability and is optimized for close-range engagements. It takes the form of a laser rifle based on the AR-15 platform, connected via cables to a backpack containing rechargeable batteries. This configuration enables continuous laser operation for up to 60 seconds, with typical engagement durations ranging from 5 to 15 seconds. The system is capable of damaging or disabling electronic sensors, cameras, and optronic equipment through thermal effects, and has demonstrated effectiveness against commercial drones such as the DJI Mavic.

Mounted on the T1 Hornet turret, the HELMA-LP benefits from integration with existing components such as the FN Herstal 12.7 mm machine gun, Galix smoke grenade launcher, and Echodyne acquisition radar. The turret itself is installed on the Sherpa Scout, a 4x4 light tactical vehicle developed by Arquus. This platform supports reconnaissance, patrol, and command missions, and is designed for air transportability and compliance with STANAG 4569 protection standards. The modular nature of both the turret and the vehicle facilitates rapid deployment and adaptation to various operational environments.

The HELMA-LP’s integration was demonstrated through live firing tests on fixed and mobile targets at distances of approximately 200 meters. Results indicated that drone optics could be neutralized within one second, and full drone incapacitation achieved in under ten seconds. These performance metrics suggest potential utility for frontline units, particularly in scenarios involving drone swarms or isolated UAV threats. The system’s silent and invisible operation further enhances its suitability for special forces and covert missions.

The broader context of this development includes a €10 million emergency equipment plan initiated by the French Army’s Technical Section (STAT), aimed at addressing capability gaps in high-intensity combat units. This plan facilitated the acquisition of technologies such as radiological detection drones, portable jamming systems, and improved command post connectivity. The HELMA-LP’s deployment aligns with this responsive procurement strategy, offering a decentralized alternative to traditional ground-to-air artillery solutions.

HELMA-P, the predecessor to HELMA-LP, remains a high-energy laser system designed for long-range engagements. It features a multi-kilowatt laser beam capable of optical jamming, neutralization, or destruction of targets such as drones, IEDs, and radar systems. With an operational range extending up to several kilometers and a wide field of view, HELMA-P has been integrated into various defense configurations, including naval platforms and fixed installations. Its development was supported by the French Directorate General for Armaments (DGA) and the Defense Innovation Agency (AID), with testing conducted at facilities such as the DGA Missile Testing Center in Biscarrosse.

The HELMA-P system emphasizes low logistical requirements, stealth operation, and precision targeting. It can be incorporated into command and control networks and is compatible with multiple detection systems, including radar and optical sensors. These attributes position HELMA-P as a strategic asset for protecting sensitive sites and critical infrastructure from aerial threats.

The HELMA-LP’s integration onto the T1 Hornet turret represents a tactical evolution in laser-based counter-drone technology. By leveraging the portability and modularity of HELMA-LP alongside the operational flexibility of the Sherpa Scout and T1 Hornet, French defense stakeholders are exploring new paradigms in decentralized electronic warfare. This approach reflects a growing recognition of the need for adaptable, frontline-ready solutions in response to the increasing prevalence of UAVs in modern conflict zones.
