Why is the D4 System Needed?
The threat from drones is increasing in India making the D4 system a much-needed technology for the country's defense.
There has been a recent rise in drone sightings along the Line of Control (LOC).
These drones have been used to drop weapons, drugs, and explosives from across the border into Indian territory.
For example, in 2023, the BSF shot down 22 such drones, seizing nearly 45 kg of heroin, grenades, and ammunition.
