Forterra has deployed over 100 autonomous ATVs in Ukraine for the past nine months, marking what the company believes is the largest deployment of autonomous ground vehicles in combat by a US defence tech company. The gas-powered Lancer vehicles, based on Polaris ATVs, can carry 750 kilograms of cargo and have driven more than 2,500 miles across 1,100 missions, completing 52 casualty evacuations. Ukrainian forces primarily teleoperate the vehicles rather than using full autonomy, as the technology cannot yet identify and respond to enemy threats independently. Forterra, which has raised over $500 million from investors including XYZ Venture Capital and Moore Strategic Partners, is working to combine traditional autonomous vehicle algorithms with generative AI. Ukrainian soldiers have requested cheaper versions to account for battlefield attrition whilst maintaining deployment flexibility.

Forterra has unveiled MESA, a modular autonomous vehicle platform designed for last-tactical-mile operations. Built on a factory-modified Polaris Ranger XD 1500, the vehicle integrates Forterra's AutoDrive® and Vektor mission modules to deliver mobility, computing, communications and sensing capabilities. The MESA platform features a flat deck design with 2,000 pounds of payload capacity, enabling rapid reconfiguration for mission-specific requirements. The system provides autonomous navigation in GPS-denied environments whilst maintaining secure connectivity across distributed forces. Forterra's autonomy technology has been proven in real-world operations including the USMC ROGUE Fires programme and various SOCOM initiatives. The vehicle is manufactured directly with Polaris, with modifications executed alongside the original equipment manufacturer to ensure platform integration without aftermarket chassis changes.
