FENRIS 6×6: John Cockerill Defense and Arquus Unveil New Wheeled Fire Support Vehicle
The FENRIS 6×6 is a new wheeled fire support vehicle developed by John Cockerill Defense and Arquus, featuring a 105 mm Cockerill 3105 turret capable of firing 36 rounds. Designed for rapid deployment, the 26-tonne platform is optimized for air transport via the Airbus A400M, filling a strategic niche between light reconnaissance assets and heavy main battle tanks.
Development and Strategic Integration

The FENRIS represents the first major collaborative project between John Cockerill Defense and Arquus since the Belgian group acquired the French armored vehicle manufacturer in July 2024. According to official company statements, the vehicle architecture leverages the mobility standards of the French Army’s SCORPION program, specifically drawing from the Jaguar 6×6 platform.
Frank Jansens, General Manager of Weapon Systems at John Cockerill Defense, stated that the design prioritizes air-transportability to ensure rapid deployment capabilities. By combining Arquus’s expertise in wheeled chassis with Cockerill’s turret technology, the manufacturers aim to provide armies with a mobile fire support option that avoids the logistical constraints associated with 60-plus tonne main battle tanks like the Leopard 2.
Armament and Technical Specifications
The vehicle is centered on the Cockerill 3105 turret, a system already in use by various international militaries. The turret houses a 105 mm NATO-standard high-pressure rifled gun.
* Ammunition Capacity: 36 rounds total, utilizing a 12-round automatic loader.
* Engagement Range: 10 to 11 km in indirect fire mode.
* Crew: Three personnel (commander, gunner, driver).
* Engine: 500 horsepower with automatic transmission.
The use of an autoloader is a primary design feature, as it eliminates the need for a fourth crew member to handle ammunition manually. This configuration allows for a sustained rate of fire while reducing the internal volume required for the turret crew.
Situational Awareness and Survivability
Rather than relying on heavy passive armor, the FENRIS platform emphasizes situational awareness to mitigate threats. The vehicle is equipped with a 360-degree external camera array and panoramic sighting systems. According to John Cockerill technical data, the integrated thermal imaging suite can detect targets at 15 km during the day and identify them at 5 km.
Arquus CEO Emmanuel Levacher noted that this focus on mobility and sensory detection serves as the vehicle’s primary defense mechanism. By identifying threats before they enter direct-fire range, the FENRIS is intended to operate as a flexible, intelligence-led asset on the modern digital battlefield.
Operational Context

The FENRIS enters a market segment increasingly focused on “medium weight” forces. Unlike heavy armor, which often requires specialized rail or heavy-lift transport, the 26-tonne FENRIS is designed to be moved quickly to regional hotspots.
This approach mirrors the tactical shift seen in other Western militaries moving toward wheeled platforms that offer high-caliber firepower without the logistical “footprint” of a traditional main battle tank. While the vehicle is not intended to replace tanks in high-intensity breakthroughs, it is positioned to provide necessary fire support for infantry units in environments where rapid movement is essential for operational success.
Key Takeaways
- Joint Development: The FENRIS is the first product of the John Cockerill and Arquus merger.
- Mobility: The vehicle is specifically engineered for transport by the Airbus A400M military aircraft.
- Firepower: The 105 mm turret allows for both direct and indirect fire support, with an engagement range of up to 11 km.
- Digital Integration: The platform is designed to operate within the shared digital battlespace architectures common to NATO-aligned forces.
