• The Indian Navy has sealed a contract with defence PSU Bharat Electronics Limited (BEL) for the supply of Naval Anti Drone System (NADS) with both hard-kill and soft-kill capabilities. 

• Both the static and mobile versions of NADS will be supplied to the Indian Navy within a short time from the signing of the contract.

What is NADS?

• The NADS, developed by the Defence Research and Development Organisation (DRDO) and manufactured by BEL, is the first indigenously developed anti-drone system to be inducted into the Indian armed forces.

• The NADS can instantly detect micro drones and uses a laser-based “kill mechanism” to terminate the targets.

• 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.

• The NADS was 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.

• Serious concerns over threats from enemy drones emerged in June when two drones were used by suspected Pakistan-based terrorists to attack the Indian Air Force (IAF) base in Jammu. Some explosives were dropped at the airbase using unmanned aerial vehicles that triggered alarm among national security planners.
