The Fourth Law (TFL), a Kyiv-based defence technology company, has announced a new funding round backed by Axon, a US public safety technology group.

TFL develops AI and robotics solutions for defence and public safety, with a focus on autonomy technologies. The company builds an autonomy-focused software stack that includes simulation and analytical tools, autonomous applications, and fleet management systems.

Technology and Applications

Designed to operate across multiple platforms, TFL’s technology can be integrated into quadcopters, fixed-wing UAVs, missiles, and ground or maritime drones. The system functions independently of satellite navigation (GNSS), allowing operation in GPS-denied environments. In addition to defence, it may also have applications beyond defence, including logistics, manufacturing, and construction.

TFL’s flagship products include the Lupynis-10-TFL-1 UAV and the TFL-1 autonomy module, which are used by more than 50 Ukrainian military units across multiple frontline areas. According to the company, its first-level autonomy technology increases FPV drone mission success rates by two to four times while adding around 10 per cent to unit costs. The company’s latest product, TFL-AntiShahed, is a module for interceptor drones that uses on-edge AI to detect and identify strike drones such as the Shahed and Geran more quickly than manual observation.

Integration and Future

TFL’s autonomy technology is designed for integration across platforms. In addition to its own Lupynis-10 UAV, the company’s AI modules have been integrated with dozens of third-party UAV manufacturers. The modules can be installed on external airframes, used with different ground stations, and operate across various connectivity architectures. Yaroslav Azhnyuk, founder and chief executive of The Fourth Law, stated that the funding will support research and development of new autonomy capabilities intended to help protect cities and critical infrastructure from Shahed-type attacks.
