Milrem Robotics Integrates Saab’s Sirius Compact with THeMIS UGV for Arctic Strike 2025

Estonian defence technology firm Milrem Robotics has successfully demonstrated its THeMIS Unmanned Ground Vehicle (UGV) at Arctic Strike 2025 (AS25), a major military exercise testing autonomous systems in extreme Arctic conditions. The exercise, conducted in collaboration with Sweden’s Defence Materiel Administration (FMV) and defence giant Saab AB, showcased the THeMIS platform's ability to operate in harsh environments while integrating advanced electronic warfare capabilities.

Equipped with Saab’s Sirius Compact electronic warfare (EW) sensor and multiple AT4 anti-tank weapons, the THeMIS UGV played a crucial role in target acquisition and battlefield intelligence. By working in coordination with other Saab Sirius Compact sensors, it provided enhanced situational awareness and supported multi-domain operations.

A key strength of the THeMIS platform is its modularity and scalability, allowing it to integrate various active and passive sensor systems. Designed to navigate challenging terrains with ease, the vehicle ensures extended operational endurance, making it an ideal choice for autonomous missions in extreme conditions.

Milrem Robotics emphasized the importance of such exercises in refining autonomous military technology. The company stated that Arctic Strike 2025 serves as a critical testing ground for integrating robotic systems into modern warfare, pushing the boundaries of autonomous intelligence and resilience in harsh environments. With military forces worldwide increasingly relying on unmanned systems, the success of THeMIS in Arctic conditions highlights its growing relevance in future defence operations.
