India’s Laser Weapon Breakthrough: Inside DRDO’s Mk-II(A)
Directed Energy Weapon and the Future of Laser Warfare
Modern warfare is undergoing a profound technological transformation. The battlefield is no longer dominated only by tanks, missiles, and aircraft. Instead, emerging technologies such as directed energy weapons (DEWs), artificial intelligence, hypersonic systems, and drone warfare are redefining military power.
In this evolving landscape, India has taken a decisive step forward. In April 2025, the Defence Research and Development Organisation (DRDO) successfully demonstrated its Mk-II(A) Laser Directed Energy Weapon (DEW)—an indigenous system capable of neutralizing aerial threats such as drones and unmanned aircraft using concentrated laser beams.
The demonstration took place at the National Open-Air Range, marking India’s entry into a select group of nations developing operational laser-based defence systems.
This breakthrough reflects India’s growing emphasis on self-reliance in defence technology under the Atmanirbhar Bharat initiative, while also addressing emerging threats from drones and autonomous weapons.
Directed energy weapons represent a new category of military systems that deliver energy—rather than physical projectiles—to damage or destroy targets.
Unlike conventional weapons that rely on kinetic energy or explosives, DEWs use concentrated forms of energy, such as:
-
High-energy lasers
-
Microwaves
-
Particle beams
Among these technologies, laser weapons have emerged as the most mature and practical option for near-term deployment.
Laser weapons operate by focusing an extremely powerful beam of light onto a target. The energy from the beam heats the target surface rapidly, causing structural failure, sensor damage, or ignition.
Key advantages of laser weapons include:
-
Speed-of-light engagement
-
High precision targeting
-
Minimal collateral damage
-
Low cost per shot
-
Virtually unlimited ammunition as long as power is available
These advantages make laser systems particularly effective against small drones, missiles, and incoming projectiles, which are difficult and expensive to intercept using traditional missiles.
The Mk-II(A) represents one of India’s most advanced directed energy weapon prototypes developed by DRDO. Designed as a vehicle-mounted anti-drone defence system, it is capable of engaging aerial targets using high-power laser beams.
Technical Characteristics
The system integrates several advanced technologies, including:
Laser Output Power
The Mk-II(A) produces approximately 30 kilowatts of laser power, generated through a combination of six synchronized 5 kW laser modules.
Effective Range
The system can engage targets at distances of 4–5 kilometres, depending on atmospheric conditions and target characteristics.
Target Capability
The weapon is designed to neutralize:
-
Small unmanned aerial vehicles (UAVs)
-
Drone swarms
-
Surveillance drones
-
Optical sensors and electro-optical equipment
-
Lightweight airborne threats
Operational Mechanism
The laser beam heats the surface of the target rapidly. Within seconds, the energy concentration can:
-
Melt structural components
-
Ignite internal electronics
-
Disable sensors and guidance systems
This makes laser weapons particularly effective against small and low-cost drones, which are becoming increasingly common in modern conflicts.
The rapid proliferation of drones in modern warfare has created new security challenges for militaries around the world.
Conflicts in regions such as Ukraine, the Middle East, and the Red Sea have demonstrated how inexpensive drones can threaten expensive military systems.
Traditional air defence systems face two major challenges:
1. Cost Imbalance
Intercepting a low-cost drone with a missile can be extremely expensive.
For example:
-
A drone may cost $1,000–$20,000
-
An interceptor missile may cost $200,000 or more
Laser weapons dramatically change this equation.
The cost per laser shot can be less than a few dollars, primarily electricity.
2. Drone Swarm Attacks
Drone swarm attacks involve dozens or hundreds of small drones attacking simultaneously.
Missile systems have limited ammunition and reload times. Laser weapons, however, can engage multiple targets sequentially without running out of ammunition.
3. Instantaneous Engagement
Laser beams travel at the speed of light, allowing immediate engagement once a target is detected.
This capability is critical for intercepting fast-moving threats such as rockets, mortars, or cruise missiles.
The Role of the Indian Armed Forces
The Mk-II(A) system is expected to support multiple branches of India’s military.
Indian Air Force
The Indian Air Force can use laser weapons to protect:
-
Airbases
-
Radar installations
-
Strategic infrastructure
Laser systems can neutralize incoming drones before they reach sensitive installations.
Indian Navy
The Indian Navy is exploring ship-mounted laser systems.
Naval laser weapons are especially valuable because warships often face threats from:
-
drones
-
small boats
-
anti-ship missiles
Future naval DEWs may operate in the 50–100 kW power range, providing defensive layers against airborne threats.
Ground Forces
For the Indian Army, vehicle-mounted laser systems could provide mobile anti-drone protection for troops and armoured formations.
The Next Step: The DURGA Program
While the Mk-II(A) system represents a major milestone, it is only the beginning of India’s directed energy weapon roadmap.
DRDO is working on a much more powerful system known as:
DURGA
The DURGA (Directionally Unrestricted Ray-Gun Array) is envisioned as a 300 kW-class laser weapon system.
Such a system would dramatically expand operational capabilities.
Potential Capabilities of DURGA
A laser weapon in the 300 kW power range could potentially:
-
Destroy large drones
-
Intercept cruise missiles
-
Damage aircraft sensors
-
Neutralize incoming artillery shells
At this power level, directed energy weapons could begin replacing certain missile-based interception systems.
Challenges in Laser Weapon Development
Despite their promise, laser weapons still face several engineering challenges.
Power Generation
High-energy lasers require significant electrical power. Mobile platforms must integrate:
-
high-capacity generators
-
energy storage systems
-
power conditioning units
Thermal Management
Laser systems generate enormous heat during operation. Efficient cooling systems are essential to maintain continuous firing capability.
Atmospheric Distortion
Laser beams can be affected by environmental factors such as:
-
dust
-
fog
-
humidity
-
atmospheric turbulence
Advanced adaptive optics and beam control technologies are required to compensate for these effects.
Target Tracking
Accurate target tracking is essential to maintain a stable laser focus on fast-moving targets.
This requires integration with:
-
radar systems
-
electro-optical sensors
-
artificial intelligence targeting systems

The Future of Warfare: Speed of Light Weapons
The demonstration of the Mk-II(A) laser weapon represents more than just a technological milestone.
It signals the arrival of a new era in military capability—where weapons no longer rely solely on physical projectiles but on precision energy delivered at the speed of light.
As research progresses and power levels increase, laser weapons may soon become standard components of military defence systems worldwide.
For India, the Mk-II(A) system represents both a technological breakthrough and a strategic investment in the future of warfare.
And as the DURGA program evolves, India may soon field some of the most advanced directed energy weapons in the world.
