About Zerov-8
Zerov-8 is a vertical-take-off interceptor designed for hostile long-range and one-way attack drones. It reaches a stated maximum speed of 326 kilometres per hour, carries a payload up to 0.5 kilograms and has a combat radius up to 20 kilometres with flight time approaching 20 minutes.
The onboard TFL detection module analyses daylight or thermal imagery, highlights aerial targets and maintains tracking while the operator chooses the engagement path. The system is designed to increase detection distance and reduce manual pursuit workload without removing the operator from the decision to intercept. The Fourth Law is offering Zerov-8 through a preorder programme.
