Rostec has introduced new technologies aimed at countering unmanned aerial vehicles (UAVs). Initially, the corporation unveiled ‘Chistulya’, a portable electronic warfare system housed in a 10-kilogram briefcase. The device is designed to block drone data transmission, control channels, and satellite navigation, and can be remotely activated to protect operators.

Following this, Rostec developed a passive radar system to detect small, silent drones that evade traditional radar and electronic reconnaissance. Unlike active radar, this 180-kilogram system does not emit signals, instead utilizing reflected waves from external sources like radio and television broadcasts to track moving objects. This system is intended for use in urban areas and near airports, providing target data to air defense and electronic warfare units when integrated with existing monitoring tools.
