About The Fourth Law
The Fourth Law develops autonomy software and modules for small drones and other robotic platforms. Its stack covers navigation, terminal guidance, simulation and mission execution in communications- or GPS-constrained environments. TFL-1 and integrated aircraft programmes apply the technology to defence missions.
The company launched the Zerov autonomous interceptor in February 2026 and signed a June agreement with RSI Europe covering production in Lithuania. These activities show a move from software modules into integrated systems and manufacturing partnerships. Product maturity, manufacturing location and field use remain specific to each named programme.
