US Navy Tests High-Energy Laser Weapon System HELIOS

The US Navy has made advancements in naval warfare technology with the successful testing of the High-Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) system. Conducted aboard the USS Preble, this test marks a very important moment in the Navy’s efforts to deploy cost-effective laser weaponry to counter emerging threats. The HELIOS system is designed to neutralise a variety of threats, including drones and missiles, enhancing the Navy’s operational capabilities.

What Is HELIOS?

• HELIOS is a high-powered laser weapon developed by Lockheed Martin.
• It operates in two modes:
  • Hard Kill: Directly destroys the target.
  • Soft Kill: Disrupts the electronic components of enemy systems.
• It boasts features such as a deep magazine, low cost per kill, speed-of-light delivery, and precision response.
• Currently, HELIOS can generate over 60 kilowatts of directed energy, with future upgrades potentially increasing this to 120 kilowatts.

Details of the Test

The HELIOS system was tested by targeting an aerial drone, demonstrating its operational capabilities. While the exact location and date of the test remain classified, it was documented in the Pentagon’s annual Director, Operational Test and Evaluation report. A notable image captured the moment the laser engaged its target, showcasing the system’s effectiveness.

Importance of HELIOS

The HELIOS system represents a more affordable alternative to traditional missile defence systems. In regions like the Red Sea and Gulf of Aden, where threats from drone and missile attacks are prevalent, the need for advanced technology is urgent. The Navy’s Vice Admiral Brendan McLane brought into light the lack of operational laser weapons, emphasising that directed-energy weapons are crucial for countering asymmetric threats.

Challenges in Development

Despite its successful test, the Navy faces several challenges in the development of laser weapons:

• Power Supply Issues: High-energy lasers require energy sources.
• Environmental Conditions: Weather factors like fog and wind can affect laser performance.
• Integration with Existing Systems: Ensuring compatibility with current onboard defence mechanisms.

The Defence Department has invested approximately $1 billion annually into high-energy laser development, although progress has been slow. The Navy has also deployed eight Optical Dazzling Interdictor (ODIN) laser dazzlers, which focus on disrupting enemy sensors rather than direct destruction.

Future of Directed-Energy Weapons

With the HELIOS system proving its effectiveness, the US Navy is likely to expand its directed-energy weapon programmes. The ability to disable threats cheaply, instead of relying on expensive interceptors, could revolutionise naval warfare. Future fleets may become more efficient and self-sustaining as these technologies are integrated.
