According to information published by the Press Information Bureau of India on August 31, 2021, the Indian Navy has signed a contract with Navratna Defence PSU Bharat Limited (BEL) for the supply of the first indigenous comprehensive Naval Anti Drone System (NADS) with both hard-kill and soft kill capabilities in New Delhi.

The contract was signed in the presence of senior Naval officers and DRDO representatives. Indian Navy has provided consistent support and has led in the joint development of the anti-drone system with the Defence Research and Development Organisation (DRDO) and BEL.

The NADS, developed by DRDO and manufactured by BEL, is the first indigenously developed anti-drone system to be inducted into the Indian Armed Forces. Multiple Units of BEL, namely Bangaluru, Hyderabad, Pune and Machilipatanam; and DRDO Labs, namely Electronics & Radar Development Establishment (LRDE), Bangaluru; Defence Electronics Research Laboratory (DLRL) and Centre for High Energy Systems and Sciences (CHESS), Hyderabad and Instruments Research & Development Establishment (IRDE) Dehradun; in close collaboration with the Indian Navy, were involved in the making of this fully indigenous system, as part of the Atmanirbar Bharat initiative to counter drone threats of adversaries.

The NADS can instantly detect and jam micro drones and use a laser-based kill mechanism to terminate targets. It will be an effective all-encompassing counter to the increased drone threat to strategic naval installations.

The anti-drone system was first deployed to provide security cover for the Republic Day Parade this year and later during the Prime Minister's Independence Day Address to the Nation from the ramparts of the Red Fort. The system, which offers 360-degree coverage, was also deployed in Ahmedabad for the Modi-Trump roadshow.

The NADS uses the help of Radar, Electro-optical/infrared (EO/IR) sensors and Radio Frequency (RF) detectors to detect and jam the micro drones. The DRDO’s RF/Global Navigation Satellite System (GNSS) detects the frequency which is being used by the controller and the signals are then jammed. The anti-drone technology system of DRDO provides for both 'soft kill' and 'hard kill' options to the Indian Armed Forces to tackle fast-emerging aerial threats. Both the static and mobile versions of NADS will be supplied to the Indian Navy within a short time from the signing of contract.

The system was deployed for VVIP protection duties during Republic Day 2020, the visit of US President Donald Trump to Motera stadium in Ahmedabad, Independence Day 2020, Republic Day 2021 and Independence Day 2021. DRDO demonstrated its counter-drone technology to different security agencies at the Hindon air force station in January 2020 and at the National Security Guard (NSG) campus in Manesar in August 2020 and January 2021.
