India has taken a significant step toward deploying directed-energy weapons after the Defence Research and Development Organisation successfully tested a 30kW laser-based counter-drone system.
The weapon, known as IDD&IS MK-IIA, is designed to defeat hostile drones using a hard-kill laser beam rather than conventional missiles or guns. By focusing a high-energy beam onto a target, the system can rapidly burn through drone structures or disable onboard electronics within seconds.
Directed-energy systems are increasingly seen as the next frontier of air defence, offering a major advantage in cost-per-shot compared with traditional interceptor missiles.
What Is DRDO’s 30kW IDD&IS MK-IIA Laser Weapon?
The IDD&IS (Integrated Drone Detection and Interdiction System) is a layered counter-drone platform developed by the Defence Research and Development Organisation to detect, track, and neutralise hostile UAVs.
The MK-IIA variant integrates a 30kW high-energy laser capable of destroying drones at distances of up to 5 kilometres.
Unlike soft-kill methods such as jamming, the laser enables a hard-kill mechanism, physically damaging the drone through intense heat. The beam can melt propellers, damage control systems, or ignite onboard batteries, rendering the drone inoperable almost instantly.
Another advantage is near-zero cost per engagement. Once powered, the system can fire repeatedly without the expense of launching interceptor missiles.
Where Was the 30kW Laser Tested?
The recent demonstration took place at the National Open Air Range, a major testing facility for advanced weapon systems.
Scientists from the Centre for High Energy Systems and Sciences, a key laboratory of the Defence Research and Development Organisation, conducted the trials under realistic operational conditions.
During the tests, the system successfully tracked multiple aerial targets and engaged drone threats using a focused laser beam, proving the weapon’s ability to counter swarm attacks.
Engineers also demonstrated advances in thermal bloom management, a critical factor that ensures laser beams maintain power and accuracy over long distances in atmospheric conditions.
DRDO’s Laser Weapon Development Roadmap
India’s laser weapon programme follows a phased development approach aimed at gradually increasing power levels and engagement capability.
| Variant | Power | Status | Primary Target |
|---|---|---|---|
| MK-I | 2kW | Operational | Small Drones (Soft Kill) |
| MK-II | 10kW | Production Phase | Tactical UAVs |
| MK-IIA | 30kW | ToT Cleared | Drone Swarms (Hard Kill) |
| Surya | 300kW | Development | Missiles & Aircraft |
The future Surya laser system is expected to deliver hundreds of kilowatts of power, potentially enabling India to intercept cruise missiles, rockets, and even aircraft.
How Does the IDD&IS MK-IIA Destroy Drone Swarms?
The system is designed to operate as part of an integrated counter-drone “kill web.”
First, radar sensors detect incoming UAV threats. Electro-optical trackers then lock onto individual targets and provide precise targeting data. Once locked, the laser generator fires a concentrated beam capable of burning through drone components in seconds.
Because the weapon travels at the speed of light, it eliminates the reaction delay associated with missile interceptors.
This capability is particularly valuable against drone swarms, where dozens of small UAVs attempt to overwhelm traditional air defence systems.
Surya 300kW Laser: India’s Next-Generation Directed Energy Weapon
While the 30kW IDD&IS MK-IIA represents a major breakthrough in counter-drone warfare, India’s long-term ambition goes much further. Scientists at the Defence Research and Development Organisation are working on a far more powerful system known as the Surya DEW (Directed Energy Weapon), expected to generate around 300 kilowatts of laser power.
The jump from 30kW to 300kW represents a tenfold increase in energy output, dramatically expanding the range of targets the weapon can defeat. While the current system is optimized for drones and small UAVs, a 300kW-class laser could potentially engage far more demanding threats such as cruise missiles, rockets, artillery shells, and even aircraft at closer ranges.
Such high-energy lasers are considered a critical component of future multi-layered air defence networks. A 300kW system could serve as a point-defence shield for high-value assets including airbases, missile batteries, radar stations, and naval vessels. Because laser weapons travel at the speed of light, they can intercept fast-moving targets much more quickly than conventional interceptors.
Another key advantage lies in sustained defensive capability. Missile-based air defence systems carry a limited number of interceptors and require resupply during prolonged engagements. In contrast, a high-energy laser like Surya can fire repeatedly as long as sufficient electrical power is available, allowing it to counter large volumes of incoming threats during extended conflicts.
The development of a 300kW-class directed energy weapon would therefore represent a massive leap in India’s defence technology. It would move the country beyond counter-drone lasers toward a new generation of energy-based air defence systems capable of neutralising missiles and other high-speed aerial threats, placing India among a small group of nations developing operational high-power laser weapons.
Global Laser Weapon Programs
Several countries are pursuing similar directed-energy systems:
- United States Navy – Ship-mounted HELIOS laser weapon programme
- Israel Ministry of Defense – Iron Beam anti-rocket laser system
- People’s Liberation Army – Ground-based counter-drone laser platforms
With the successful testing of the 30kW IDD&IS MK-IIA, India is now moving closer to deploying operational laser-based air defence systems, potentially making it one of the few nations capable of fielding combat-ready directed-energy weapons.
