The Fourth Law

Defense marketperceptionsafetyCurated record
thefourthlaw.ai

Builds massively scalable AI autonomy systems for FPV strike drones. Flagship TFL-1 module takes over control of the drone for the final 400-500 m of flight, using onboard machine-vision terminal guidance to hit operator-designated stationary or moving targets through electronic-warfare jamming. Claimed to raise FPV mission success 2-4x while adding only 10-20% to drone cost. In operational use across 50+ units of Ukraine's Defence Forces; mass production of TFL-1-equipped FPVs launched with manufacturer Vyriy in September 2025. Part of the Brave1 defense-tech ecosystem, with offices in Ukraine, the EU and the US.
