Patria TREMOS: redefining battlefield mobility with modular firepower

The Patria TREMOS mortar system is modular to optimise available space and versatile enough for quick refit on another vehicle. It offers robust protection and freedom for creative problem-solving. Operators control the mission tempo, not the logistics.

Picture this: armed forces are in the heat of battle. A unit is stationed on a rugged hillside, mortar tubes locked on multiple enemy targets. Every second counts. Once they shoot, they must quickly reposition to avoid incoming fire from all directions.

But the mortar system’s slow setup time and the presence of unmanned aerial vehicles mean their window to hide after firing is shrinking fast. The stress is already immense, and with war’s unpredictable nature, there’s always the looming chance something could go wrong with the vehicle itself. In that moment, what are their options?

Patria TREMOS was designed for exactly this. Its recoil absorber technology enables the vehicle to withstand the shock of firing without the need for separate support legs, eliminating wasted time in lowering or raising them. In practical terms, TREMOS can fire within 60 seconds of arriving at its position and exit within seconds after the last shot, enabling true “shoot and scoot” tactics.

Modularity on the battlefield

Battlefields are unpredictable, especially for mortar units operating on uneven terrain under constant threat. The risk of equipment damage is high, and losing both a vehicle and its mortar system can tip the balance of an engagement. What’s the alternative? For Patria, the answer was clear: modularity on the battlefield.

That is why TREMOS features a proven standardised container base with twist-locks, allowing it to be dismounted and transferred to another platform in field conditions, if there is sufficient load-bearing capacity. This can be done in minutes with the help of a forklift or front-end loader. To enhance protection, additional ballistic plates supplied by Finnish manufacturers can be quickly installed. 

Additionally, Patria TREMOS is compatible with all qualified 120mm and 81mm smoothbore mortar ammunition, making it a truly versatile and modular system that delivers critical battlefield flexibility. It can be equipped with existing barrels, enabling the use of available qualified ammunition and ballistic tables, making it easy to train and speeding up system deployment.

With Patria TREMOS, forces don’t just adapt to the battlefield – they shape it.
