Insider Brief

  • Milrem Robotics and UK partners Overwatch Aerospace, MSI-Defence Systems, and Pearson Engineering have launched a UK-specific version of the THeMIS Combat Unmanned Ground Vehicle (UGV) at DSEI 2025.
  • The platform combines Milrem’s THeMIS UGV with MSI’s TERRAHAWK remote weapon station and Overwatch’s APEX unmanned aerial system, while Pearson provides integration expertise to tailor the vehicle to UK operational needs.
  • Development, testing, and production will take place in the UK, with the program now entering trials to deliver a deployable, scalable robotic combat solution for the British Army.

PRESS RELEASE – Milrem Robotics, the world’s leading developer of robotic and autonomous systems, along with Overwatch Aerospace Ltd, MSI-Defence Systems Limited (MSI-DS), and Pearson Engineering Limited, has announced the launch of a UK-specific version of the THeMIS Combat Unmanned Ground Vehicle (UGV) at DSEI 2025. This strategic relationship will see the four companies develop, test, demonstrate, and produce the combat-proven THeMIS platform in the United Kingdom, specifically designed to meet the needs of UK customers.

The UK version of the THeMIS Combat UGV will combine Milrem Robotics’ battlefield-proven THeMIS UGV platform with MSI-Defence Systems’ advanced TERRAHAWK Remote Weapon Station (RWS) and Overwatch Aerospace’s innovative APEX Unmanned Aerial System (UAS). Pearson Engineering will contribute its proven expertise in integrating mission-critical capabilities into armoured platforms, ensuring the vehicle is optimised for survivability, mobility, and adaptability to UK operational requirements.

Kuldar Väärsi, CEO of Milrem Robotics, said: “The THeMIS has proven its value in multiple theatres worldwide, and this UK-specific variant will take its capabilities even further. By working with trusted British partners, we deliver an advanced and mission-ready combat system and ensure that development, testing, and production happen here in the UK, creating local value and strengthening domestic defence capabilities.”

Drew Michael, CEO of Overwatch Aerospace Ltd, said: “Integrating our APEX UAS into the THeMIS Combat UGV introduces a completely new dimension to battlefield awareness and adaptability. By merging unmanned ground and aerial capabilities into a unified system, we enable forces to operate more effectively, with improved situational awareness and lower risk to personnel. This collaboration ensures our innovation directly aligns with UK defence priorities.”

Brigadier (ret) Haydn White, Senior Military Adviser at MSI-Defence Systems, stated: “The MSI-DS TERRAHAWK RWS is our fully stabilised remote weapon station, which offers exceptionally precise firepower and situational awareness in a package designed for rapid integration with a wide range of payloads and sensors. Collaborating with Milrem Robotics on this UK-focused UGV demonstrates how the best of British engineering, combined with proven international platforms, can deliver world-class capability to the British Army.”

Ian Bell, CEO of Pearson Engineering Limited, added: “Pearson Engineering will ensure that the THeMIS Combat UGV is adapted perfectly for UK operational environments and that it delivers reliable performance in the most challenging conditions. This partnership highlights our shared commitment to lead the industry into a new era of innovation and safety.”

The program will now move into a comprehensive development and trial phase, with the goal of delivering a deployable, scalable, and enduring robotic combat solution for the British Army.
