How French Army Revamped Old Cannons into 20mm Proteus for Drone Combat.
In response to the growing presence of drones on modern battlefields, the French Army unveiled the Proteus cannon in a video released on January 23, 2025. This innovative system repurposes old AA53 T2 anti-aircraft cannons into an effective tool for counter-drone operations. By integrating a SANDRA thermal camera, originally designed for the Mistral missile, and modernizing the fire control system, Proteus represents an efficient and economical solution to address emerging aerial threats.

Developed in just four months by the French Army's Technical Section (STAT) and the Ministry of Defense's Artificial Intelligence Agency (AMIAD), the Proteus Standard 1 enhances short-range anti-aircraft capabilities. Equipped with a targeting system optimized by algorithms, it delivers increased accuracy against fast and agile drones. The first units are expected to be delivered to the 35th Parachute Artillery Regiment (35e RAP) in early 2025, while a prototype of Standard 2, featuring advanced artificial intelligence (AI) capable of predicting drone trajectories, is slated for mid-2025. This upgraded version is projected to improve operational efficiency by 30% compared to conventional systems.
One of Proteus' key strengths lies in its ability to repurpose existing equipment. The AA53 T2 cannons, previously considered outdated, have been adapted to meet the demands of modern conflicts. By incorporating a laser designation system and an advanced fire control system, Proteus offers a cost-effective alternative to expensive missile systems, particularly for addressing specific threats such as drone swarms or low-altitude light drones.
The Standard 1 marks a significant milestone, showcasing improved firing performance and simplified operator procedures. Meanwhile, Standard 2 introduces predictive capabilities through AI, enabling precise calculations of drone trajectories and optimized engagement angles. This approach highlights an agile and iterative development strategy, supported by close collaboration between the armed forces, technological agencies, and the French defense industry.
The 17th Artillery Group (GA) in Biscarrosse plays a pivotal role in advancing counter-drone and all-arms anti-aircraft capabilities. Through its National Evaluation and Training Center for All-Arms Anti-Aircraft Warfare (CNEF LATTA), the 17th GA is at the forefront of the Army's transformation. Its advanced facilities enable testing and refinement of innovative systems such as Proteus, while also providing training for ground forces on emerging defense technologies.
Additionally, the group has demonstrated innovation in producing low-cost drone targets, essential for troop training. By leveraging 3D printing and developing drones like the SL 450 NG, the 17th GA has addressed the growing need for realistic training targets. This focus on autonomy and responsiveness reflects the group's commitment to continuous innovation.
The Proteus project aligns with a broader strategy to modernize short-range air defense capabilities in France. Supported by the Task Force LAD, established in 2024 to accelerate technological solutions against drones, the initiative aims to develop modular and scalable systems. These systems must integrate seamlessly with existing platforms, such as the Scorpion vehicle range, while remaining adaptable to rapid technological advancements.
Proteus also holds strategic potential for export. Its cost-effective, high-performance design, tailored to modern conflicts, could appeal to foreign armed forces facing similar challenges. The integration of predictive algorithms into other systems, such as remote-controlled turrets, is also under consideration, further enhancing the interoperability and versatility of French counter-drone capabilities.
Looking ahead, the Army plans to strengthen its counter-drone capabilities by exploring new solutions, such as turrets equipped with sensors and active neutralization systems. Incorporating Proteus into a broader ecosystem, including modern tactical vehicles like the Serval, could mark a significant step in transforming France’s ground forces.
The 20mm Proteus cannon demonstrates the French Army's ability to innovate swiftly to meet the challenges of modern conflicts. By repurposing legacy equipment into advanced technological solutions, the project reflects a pragmatic and forward-thinking approach to defense.
Amid the growing proliferation of drones on operational theaters, Proteus provides an effective, economical, and adaptable response. Its rapid development, backed by close collaboration across the defense sector, offers promising prospects for enhancing national capabilities and exporting viable solutions. With Proteus, the French Army reinforces its commitment to preparing for the challenges of future battlefields.
