History
Development History
The origins of the Fenris can be traced back to the transformation of the European defense industry during the mid-2020s. In 2024, Belgian defense company John Cockerill Defense completed its acquisition of French military vehicle manufacturer Arquus, creating one of Europe’s most comprehensive land systems groups. For John Cockerill, the acquisition represented far more than a simple business expansion; it provided the company with a manufacturer capable of producing complete armored vehicle chassis, allowing it to move beyond its traditional role as a supplier of weapon systems and turrets.
Prior to the acquisition, John Cockerill had achieved considerable success with its Cockerill 3000-series turrets, which had been integrated onto numerous tracked and wheeled platforms around the world. However, the company still relied on external manufacturers to provide the vehicles themselves. By acquiring Arquus, John Cockerill gained access to a portfolio of established armored vehicles, including the Sherpa, Bastion, Griffon, Serval, and most importantly, the EBRC Jaguar.
In January 2026, John Cockerill Defense CEO Jean-Luc Maurange publicly confirmed that discussions were underway regarding the development of a 105 mm-armed derivative of the Jaguar. The project was presented as a logical extension of both the Franco-Belgian CaMo partnership and the company’s newly acquired industrial capabilities. The goal was to create a vehicle capable of delivering significantly greater direct-fire support while preserving the mobility, networking capabilities, and deployability of the original Jaguar.
Early reports indicated that the concept would utilize the existing Jaguar chassis together with the Cockerill 3105 turret, a mature and already fielded system that had previously been integrated onto several tracked and wheeled platforms. This approach dramatically reduced development risks and allowed engineers to focus on vehicle integration rather than developing entirely new subsystems.
Throughout the first half of 2026, reports from industry observers and defense journalists suggested that integration work was progressing rapidly. The project was frequently described as the first true demonstration of the synergies created by the Arquus acquisition, combining a French-developed combat vehicle with a Belgian-designed turret system.
The completed vehicle was officially unveiled during Eurosatory 2026 under the name Fenris. Presented jointly by Arquus and John Cockerill Defense, the vehicle immediately attracted considerable attention as the first armored fighting vehicle fully developed within the newly unified group. During the exhibition, company representatives emphasized the vehicle’s combination of mobility, firepower, and strategic deployability, describing it as a modern fire support vehicle positioned within the same operational family as the AMX-10RC while benefiting from decades of technological progress.
Additional information released during and after Eurosatory indicated that hull and turret integration had already been completed and that live-fire testing was expected to begin shortly thereafter. The vehicle is currently being marketed as a highly mobile fire support platform for both existing Jaguar operators and export customers seeking a lightweight alternative to larger wheeled gun systems.
Design and Layout
Vehicle Architecture
The Fenris is built around the chassis of the EBRC Jaguar, one of the most advanced wheeled combat vehicles currently in European service. Developed as part of the French Army’s Scorpion modernization program, the Jaguar was designed to replace aging platforms such as the AMX-10RC and ERC-90 Sagaie while introducing a new generation of digital networking, survivability, and reconnaissance capabilities.
The vehicle retains the Jaguar’s highly mobile 6×6 configuration and advanced electronic architecture, allowing it to integrate seamlessly into modern network-centric battlefield environments. This provides the Fenris with a level of situational awareness and command-and-control capability rarely seen on vehicles within its weight class.
To create the Fenris, the original T40 turret armed with the 40 mm CTA cannon was removed and replaced by the Cockerill 3105 two-man turret.
The Cockerill 3105 is among the most advanced turret systems currently available in its class. Constructed from welded ballistic aluminum and designed for installation on both tracked and wheeled vehicles, the turret combines relatively low weight with substantial firepower. Its compact design allows the integration of a high-pressure 105 mm gun without requiring a significantly larger chassis.
The turret employs an autoloading system and accommodates a crew of two, while the driver remains in the hull. As a result, the Fenris retains the Jaguar’s three-man crew arrangement:
- Driver
- Gunner
- Commander
One of the turret’s most notable features is its advanced observation and fire-control suite. Both the commander and gunner are provided with identical stabilized day/night sights equipped with thermal imaging systems, laser rangefinders, and hunter-killer functionality. This enables the commander to independently search for and designate targets while the gunner engages another, significantly improving target acquisition and engagement speed.
Additional systems advertised for the turret include laser warning receivers, acoustic gunshot detection systems, optional active protection systems, and a complete 360-degree camera suite for enhanced situational awareness.
Another particularly distinctive characteristic of the Fenris is the turret’s exceptional elevation range of −10° to +42°. This far exceeds the elevation capability of most conventional tank destroyers and fire support vehicles and could provide unique tactical opportunities in both real-world operations and War Thunder gameplay.
Despite carrying a 105 mm gun, the Fenris remains considerably lighter and more deployable than a main battle tank. According to information presented at Eurosatory, the vehicle remains compatible with Airbus A400M strategic air transport, reinforcing its role as a rapidly deployable expeditionary fire support platform.
Firepower
Main Armament
The primary armament of the Fenris is the Cockerill High Pressure 105 mm Gun mounted within the Cockerill 3105 turret.
The weapon is fed by an automatic loading system and can fire the full family of NATO-standard 105 mm ammunition in addition to gun-launched anti-tank guided missiles.
The autoloader is reported to achieve a reload time of approximately 5 seconds, giving the vehicle a rate of fire superior to many manually loaded vehicles armed with larger caliber guns.

In addition to conventional ammunition, the vehicle can fire the Falarick 105 gun-launched anti-tank guided missile. This missile uses a tandem-charge warhead and is advertised as capable of penetrating more than 550 mm of armor behind explosive reactive armor.
Secondary Armament
- 1 × 7.62 mm FN MAG coaxial machine gun
- Optional roof-mounted weapon station
Protection
Survivability
Although the Fenris is not intended to function as a main battle tank, it incorporates numerous survivability features common to modern armored fighting vehicles.
The turret can be protected up to STANAG 4569 Level 5 standards depending on customer configuration.
Protection systems include:
- Laser Warning Detection System (LWD)
- Acoustic Gunshot Detection System
- Eight smoke grenade launchers
- Optional Active Protection System (APS)
- Day/night 360° situational awareness cameras
- NBC protection
Like the standard Jaguar, the Fenris relies heavily upon mobility, sensors, and battlefield awareness rather than armor thickness.
Its ability to detect threats before being detected remains one of its primary defensive advantages.
Mobility
Mobility
Because the vehicle retains the Jaguar chassis, mobility remains one of the Fenris’ strongest characteristics.
The 6×6 chassis provides excellent strategic and tactical mobility while maintaining a smaller logistical footprint than larger 8×8 wheeled gun systems.
Estimated characteristics include:
- Maximum road speed: approximately 90 km/h
- Operational range: approximately 800 km
- 6×6 drivetrain
- Independent suspension
- High cross-country mobility
Compared to many existing wheeled gun systems, the Fenris benefits from a relatively compact size while still carrying a powerful 105 mm weapon.

Place in War Thunder
Implementation
The Fenris would fit naturally within the French ground forces tree due to its Franco-Belgian origins and its use of the Jaguar chassis.
The vehicle would likely occupy a position behind the Vextra or similar vehicles.
Gameplay would focus on:
- Exceptional mobility
- Fast autoloading 105 mm gun
- Advanced thermal sights
- Gun-launched ATGMs
- Excellent gun handling
- Powerful APFSDS ammunition
Compared to vehicles already present in War Thunder, the Fenris would most closely resemble a hybrid of the Rooikat 105, Boxer MGS, and M1128 Stryker MGS while possessing significantly more modern optics and fire-control systems.
A Battle Rating between 10.7 and 11.0 would likely be appropriate depending on ammunition selection.
With access to the M1060CV and Falarick 105, it could become one of the most capable wheeled fire support vehicles available to France.
