The Defence Research and Development Organisation (DRDO) of India is advancing its Directed Energy Weapons (DEW) capabilities with the development of a high-energy laser weapon system known as "Surya." This system is designed to deliver a 300-kilowatt laser beam with an effective range of 20 kilometers, positioning it among the most powerful laser weapons under development globally.
The United States has been at the forefront of directed-energy weapon development for years, with systems like the High Energy Laser Weapon System (HELWS) designed to counter drones, rockets, and artillery shells. The LaWS (Laser Weapon System) aboard the USS Ponce, which was tested in the Persian Gulf, was an early example of a laser system capable of engaging targets at close ranges. The U.S. military is now focusing on higher-energy systems like the AN/SEQ-3 Laser Weapon System, which can reach powers up to 150 kW, with plans for future systems in the 500 kW range.'
Russia has made remarkable progress in directed-energy weapons, with one of its most notable systems being the Peresvet, introduced in 2018. Believed to function as an anti-satellite weapon, it likely boasts a power output in the hundreds of kilowatts. Additionally, Russia has developed laser-based systems for countering aircraft and drones, targeting both ground-based and space-based threats.
Israel has also showcased its expertise in laser weapon systems with the development of the Iron Beam, designed to intercept short-range rockets, mortar shells, and UAVs. Operating with a laser of approximately 100 kW, the Iron Beam has demonstrated promising operational capabilities during trials, though it is not as powerful as the Surya.
China is rapidly advancing in directed-energy weapons, with systems like the ZKZM-500 (50 kW) for disabling vehicles and personnel and the Sheng-1 (100 kW) for countering drones. Speculation suggests China aims for lasers with a 50 km range. However, India's 300 kW Surya, with a 20 km range, positions it strongly in this field.
Key Features of the Surya Laser Weapon System:
-
High Power Output: The 300 kW laser is capable of engaging high-speed threats, including unmanned aerial vehicles (UAVs), rockets, and incoming missiles.
Extended Range: With an operational range of 20 kilometers, Surya can neutralize threats at a considerable distance, enhancing standoff defensive capabilities
Development Context:
The Surya project represents a significant leap in India's DEW initiatives. Prior to this, DRDO has been working on the Directionally Unrestricted Ray-Gun Array (DURGA) II, a 100-kilowatt lightweight DEW system. The DURGA II project focuses on developing laser-based weapons for intercepting missiles during their boost phase, as part of India's ballistic missile defense strategy.
In 2017, DRDO tested a 1 kW laser weapon mounted on a truck at a test facility in Chitradurga. This test marked an initial step towards more powerful laser systems, demonstrating the feasibility of laser-based defense mechanisms.
Strategic Implications:
The development of the Surya laser weapon aligns with global trends in modernizing military arsenals with DEWs. Such systems offer precision targeting, reduced collateral damage, and cost-effective operation compared to traditional missile-based defense systems. For India, integrating the Surya system would enhance both defensive and offensive capabilities, providing a strategic edge in modern warfare scenarios.
Current Status and Future Prospects:
As of March 2025, DRDO continues to advance the development of the Surya laser weapon system. While specific timelines for deployment have not been publicly disclosed, the progression from earlier projects like DURGA II and the 1 kW laser test indicates a focused effort towards operationalizing high-energy laser weapons. The successful integration of the Surya system would mark a significant milestone in India's defense technology landscape
