John Cockerill Defense and Arquus used Eurosatory 2026 in Paris to debut Fenris, a 26-tonne 6×6 fire support vehicle built around the Cockerill 3105 turret and its 105 mm gun. The platform was developed in just over a year as a dedicated wheeled answer to direct-fire support needs exposed by Ukraine, with a 500 hp powerpack, A400M airliftability and NATO STANAG 4-level protection.
Fenris is pitched as the gap-filler between light reconnaissance vehicles and main battle tanks, giving operators tank-class firepower without the logistics drag of tracked armor. The turret adds counter-drone protection, and John Cockerill is targeting first deliveries in 16 months, or faster for urgent orders. That timeline now becomes the real test.
