John Cockerill Unveils Fenris Combat Vehicle at Eurosatory
Belgian defense giant John Cockerill has unveiled its new Fenris combat vehicle at the Eurosatory defense exhibition near Paris, marking the first major product to emerge from the company’s acquisition of French armored vehicle manufacturer Arquus. The 26-ton, 6x6 armored vehicle was presented on the opening day of the biennial exhibition on June 15, 2026, as reported by La Libre Belgique.
A Franco-Belgian Industrial Milestone
The Fenris — named after a wolf from Norse mythology “that unleashes misfortune upon its enemies” — represents the successful integration of Belgian turret technology with French chassis expertise. John Cockerill finalized its acquisition of Arquus in June 2024 with financial backing from both the Belgian and French governments, a deal that has now produced its first tangible result.
John Cockerill CEO Jean-Luc Maurange described the Fenris as “the first baby” of the union with Arquus, emphasizing that it was “thought and designed” in both Belgium and France. Joan Gibert, Product Manager at Arquus, called it “the first vehicle that symbolizes the marriage between Arquus and John Cockerill,” adding that the Fenris “has top-level mobility and enables operational superiority.”
Technical Specifications
The Fenris is equipped with a Cockerill 3105 turret featuring a NATO-standard 105 mm high-pressure cannon, described as the lightest operational 105 mm turret currently available. The vehicle carries a 12-round autoloader with two additional ammunition sets, giving it a total capacity of 36 munitions. Its secondary armament includes two twin 7.62 mm machine guns, panoramic sights, and a 360-degree external camera system.
Powered by a 500-horsepower engine with automatic transmission, the 26-ton vehicle features active suspension technology with adjustable ride height — a capability more commonly associated with main battle tanks. The Fenris can be configured as either 6x6 or 6x4 and is compatible with Airbus A400M aircraft for rapid air deployment.
A notable innovation is the integration of counter-drone protection directly into the turret architecture via the Hornet-S commander’s sight in C-UAS configuration, equipped with radar sensors and a MAG 58 machine gun. This reflects the growing threat of drones on modern battlefields, a lesson reinforced by the war in Ukraine.
Operational Role
According to a company statement, the Fenris responds to “the shared observation by many armies of the need for direct fire support that exists and persists on the modern battlefield.” The vehicle is not intended “to replace modern main battle tanks, but rather to complement them with intelligence and flexibility.”
The Fenris fills a specific operational niche between light reconnaissance vehicles and main battle tanks. It is designed for long-range covert reconnaissance, direct fire support against armored vehicles and fortified positions, indirect fire support up to 10-11 km, and rapid expeditionary operations. Its target detection capabilities reach up to 18 km during daytime and 15 km at night.
Frank Jansens, General Manager of Weapon Systems at John Cockerill Defense, highlighted that the vehicle is “easily air-transportable via an Airbus A400M” and highly mobile in any environment. The vehicle offers protection against 25 mm sub-caliber rounds.
Market Position and Outlook
The Fenris development concept was initiated in mid-February 2025, and the prototype was completed rapidly. The vehicle is ready for mass production immediately, with an estimated delivery timeline of approximately one year.
The vehicle targets a growing market segment for medium-weight, highly mobile combat vehicles with heavy firepower — a niche between infantry fighting vehicles and main battle tanks. With its air-transportable design and NATO-standard armament, the Fenris is positioned for international sales to armies seeking rapidly deployable direct-fire support capabilities.
The unveiling comes as John Cockerill’s defense sector, which represents approximately 50% of the group’s results, continues to expand. The company recently surpassed €2 billion in orders based on 2025 figures, and the Fenris is expected to further strengthen its position in the global defense market.
What’s Next
The Eurosatory 2026 exhibition, running from June 15 to 19, provides the platform for John Cockerill to showcase the Fenris to potential international buyers. The vehicle enters a competitive landscape that includes the French EBRC Jaguar, on whose chassis it is based, and various other wheeled combat vehicles with medium-caliber guns. Industry observers will be watching closely for initial orders and expressions of interest from European and allied armies seeking to modernize their armored vehicle fleets.
