Defence Research and Development Organisation (DRDO) is working on Directed energy weapons(DEWs) as part of ongoing efforts to modernize defence technology.
Direct energy weapons(DEW) is a ranged weapon that damages its target with highly focused energy, including laser, microwaves and particle beams.
DEW can quietly disable enemy drones or missiles temporarily or permanently without leaving physical debris.
In contrast,the ASAT or anti-satellite missile that the DRDO tested had killed an orbiting Indian target satellite and left hundreds of small pieces as debris for a few months.
The potential applications of this technology include weapons that target personnel, missiles, vehicles and optical device.Only the US, China, Russia, UK and India are known to be developing directed-energy weapons.
After decades of R&D,directed-energy weapons are still at experimental stage and it remains to be seen if or when they will be deployed as practical,high-performance military weapons.
