The system, known as the D4 Counter-UAS, is fitted with a 10/12 kW multi-channel directed-energy weapon
India’s Defence Research and Development Organisation (DRDO) has unveiled a domestically developed counter-drone system equipped with a high-powered laser weapon, as the country steps up efforts to combat the growing threat from unmanned aerial vehicles.
The system, known as the D4 Counter-UAS, is fitted with a 10/12 kW multi-channel directed-energy weapon and has been designed to detect, jam and destroy hostile drones. It combines radar, radio-frequency sensors, electro-optical tracking, GPS spoofing and laser strikes in a layered defence approach.
Developed by DRDO’s Centre for High Energy Systems and Sciences in Hyderabad, the weapon is mounted on a mobile platform and is capable of engaging multiple targets at once. Officials said it offered a far cheaper alternative to missile-based air defence, with operational costs likened to burning only a few litres of fuel per engagement.
The process begins with detection by radar and RF sensors, followed by visual confirmation through cameras with laser rangefinders. Operators can then choose between a “soft kill” through electronic jamming or a “hard kill” with a laser strike. A 360-degree electro-optical targeting system provides real-time tracking data to guide the weapon.
Trials have demonstrated the D4 system intercepting drones simulating smuggling and surveillance missions. Defence analysts said it marked a step forward in India’s bid for military self-reliance, adding the country to a small group with advanced laser-based counter-drone capabilities.
The unveiling follows the Indian Navy’s deployment of a 2 kW system and the testing of a 30 kW variant capable of destroying targets up to five kilometres away. DRDO is continuing work on even more powerful systems aimed at meeting future battlefield requirements.
