John Cockerill has delivered to Ukraine a modernized version of the Leopard 1 tank, equipped with the new Cockerill 3105 turret.
The update represents a significant advance in the vehicle’s operational capabilities, especially in the indirect fire field, highlighted by the company as a rare differentiator among Western armored vehicles.
The modernization includes state-of-the-art optical systems capable of identifying targets up to 18 km during the day and 15 km at night. Furthermore, the turret offers greater protection against 25 mm projectiles and an automatic loader with capacity for up to 16 shots, increasing combat efficiency.
Another highlight is the new internal design, which repositions the shooter and commander at hull level, increasing crew safety. The main armament remains a 105 mm cannon, compatible with the Leopard 1’s traditional ammunition and also with the Ukrainian Falarick anti-tank missile, expanding the system’s versatility.

According to Frank Janssens, the tower is made of armored aluminum, being lighter than the original and maintaining a high level of protection, with the possibility of incorporating additional defensive systems. The effectiveness of the modernization has already been proven in combat, while Ukrainian units continue to be reinforced with these tanks adapted for the current war scenario.
