The Fourth Law unveils new autonomous interceptor drone Zerov-8

Ukrainian defence tech company The Fourth Law has unveiled a new interceptor drone, the Zerov-8. The system is equipped with a TFL Anti-Shahed detection module designed to enhance its autonomy. The developer shared product details with Defender Media.

The interceptor features vertical take-off and landing, a maximum speed of 326 km/h, and the capability to intercept targets travelling at up to 270 km/h. Its combat radius extends to 20 km, and it carries a warhead of up to 0.5 kg. The system can be fitted with either a day or thermal camera.

The system’s defining feature is autonomous detection, according to the company. To achieve this, the interceptor employs the TFL Anti-Shahed module, which is installed on board alongside a thermal imaging camera, flight controller, or video transmitter. The system operates as follows:

• The system autonomously detects a drone by analysing the object’s movement, its thermal signature, and other parameters using AI;
• Upon detection, the system “highlights” the target and continues tracking it. The pilot independently selects the approach direction.

The autonomous system can detect a drone at up to 1 km under ideal (high-contrast) conditions and up to 300 m in adverse weather.

The Zerov-8 is currently undergoing final trials of a full autonomous interception cycle. In the future, it will be capable of integrating with external radars for automatic interception trajectory guidance, the company states.

In addition to the Zerov-8, Chetvertyi Zakon’s portfolio includes another drone, the Lupynis-10-TFL-1, and the TFL-1 autonomy module. According to the company, these products are used by more than 50 military units.
