DRDO's D4 anti-drone system proves formidable at border
India's DRDO-developed D4 system is thwarting Pakistani drone incursions along the western border. Using radar, RF sensors, jamming, spoofing, and laser weapons, the 'Detect, Deter, Destroy' system has become a key defence tool. Deployed by all three services and made by BEL under 'Make in India,' it neutralises threats with soft and hard kill capabilities.
