The U.S. Navy has unveiled a striking image of the USS Preble (DDG-88) deploying its High-Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) system. This photograph underscores the Navy’s dedication to advancing directed energy weapons.
HELIOS: A New Era in Naval Defense
HELIOS, developed by Lockheed Martin, signifies a significant advancement in naval defence technology. This system merges a high-energy laser with optical dazzling and surveillance capabilities, offering a comprehensive defense mechanism. Its design enables both the physical destruction of threats and the disruption of enemy sensors.

Capabilities and Integration
HELIOS is engineered to counteract threats such as unmanned aerial vehicles (UAVs), small boats, and potentially incoming missiles at close range. Operating at a power level of over 60 kilowatts, the system is scalable, allowing adjustments to meet various operational requirements. Its integration with the Aegis Combat System enhances the USS Preble’s defensive and offensive operations.
Deployment and Testing
The USS Preble is the first naval vessel equipped with the HELIOS system. The Navy has conducted rigorous testing to validate its performance, including successful engagements with UAV targets. These evaluations confirm HELIOS’s readiness and inform future enhancements.
Global Developments in Laser Weaponry
Globally, several nations are investing in high-energy laser technology:
- United Kingdom:
The UK’s “DragonFire” laser weapon system, with a power output of 50 kilowatts, aims to counter aerial threats like drones and missiles. A successful trial in early 2024 demonstrated its capability by engaging an aerial target.
- Israel:
The “Iron Beam” system is designed to complement its existing Iron Dome missile defense by focusing on intercepting rockets, mortars, and drones at a lower cost per shot than traditional interceptors.
- China:
Chinese scientists have announced the development of a laser weapon capable of firing indefinitely due to an innovative cooling system, suggesting a potential shift in laser weapon deployment.
- Russia:
Russia has programmes aimed at creating ground-based, high-energy lasers, notably for anti-satellite purposes, indicating a focus on space warfare capabilities.
- Germany:
Germany, through companies like Rheinmetall, has been developing both stationary and mobile high-energy laser systems intended for a broad spectrum of threats, from drones to artillery shells.
- India:
India’s Defence Research and Development Organisation (DRDO) is working on the “DURGA II” project, a high-power laser weapon system intended to counter both aerial and ground threats.
- Turkey:
Turkey’s ALKA system, developed by Roketsan, combines laser and electromagnetic weapons to tackle drones and other small threats, enhancing its defense capabilities amidst regional tensions.
- South Korea, Japan, and Australia:
These nations are also investing in laser weapon technology, focusing on integrating laser weapons into their defense strategies to counter various threats.

Challenges and Future Prospects
Despite the advanced capabilities of systems like HELIOS, challenges such as power generation and atmospheric conditions affecting laser effectiveness remain. The Navy is actively addressing these issues, including enhancing shipboard power systems to meet the high energy demands.
The deployment of HELIOS on the USS Preble marks the beginning of a broader plan to integrate targeted energy weapons across the fleet, aligning with efforts to develop cost-effective defense solutions for evolving threats.
The integration of HELIOS into naval operations not only enhances the defensive posture of U.S. naval forces but also signals a shift towards more sustainable and technologically sophisticated defense mechanisms.
