The Defence Research and Development Organisation (DRDO) is concentrating on developing advanced defense systems and technology applications, with a special emphasis on anti-drone technology. DRDO has developed the indigenously-built Drone Detect, Deter and Destroy system (D4S), which is capable of detecting and countering rogue drones. D4S can instantly jam micro drones (soft kill) and employ a laser to destroy drones (hard kill). The technology has a range of up to 3 km for jamming micro-drones and can target at distances of 1-1.25 km with a laser. DRDO aims to export its technology to multiple countries and is working to build an ecosystem for indigenous systems while focusing on reducing imports.
