Editors Picks: Are High-Energy Laser Weapons Ready To Fulfil Their Potential?

Why It Matters

Operational HELs would provide a low‑cost, scalable shield against drone swarms and, eventually, high‑speed missile threats, fundamentally altering air‑defense economics and strategy.

Key Takeaways

• High‑energy lasers have existed since 1960s but remained experimental.
• Recent advances push lasers toward operational deployment against drone swarms.
• Solid‑state lasers now replace outdated chemical systems for defense.
• Current lasers can neutralize low‑speed drones, loitering munitions.
• Future upgrades aim to target ballistic missiles and hypersonic threats.

Summary

The editors’ pick focuses on whether high‑energy laser (HEL) weapons are finally ready to move from laboratory prototypes to fielded defensive systems. Joanne Samo and Defense Editor Steve Trimble discuss the technology’s long history, noting that while concepts date back to the early 1960s, operational deployment has been repeatedly delayed by over‑promising and under‑delivering.

Trimble highlights two converging trends: rapid improvements in solid‑state laser power and the evolving threat landscape that now emphasizes swarms of inexpensive drones and loitering munitions. Recent live‑fire demonstrations have shown that current HEL units can reliably destroy slow‑moving, lightweight targets, a capability that aligns with the immediate needs of U.S. forces and allies.

A key quote from the interview underscores the shift: “Solid‑state lasers are now coming of age… ready to take on some of the initial threats and move beyond that into ballistic missiles and even hypersonic vehicles.” The story cites multiple test events where laser systems disabled dozens of drones in minutes, proving scalability and cost‑effectiveness compared with traditional kinetic interceptors.

If the development trajectory continues, HELs could become a cornerstone of layered air‑defense, reducing reliance on expensive missiles and expanding protection against emerging autonomous threats. Their eventual ability to engage high‑speed ballistic and hypersonic weapons would reshape strategic planning for both the U.S. and its partners.

Original Description

As high-energy lasers become weapons for countering small drones, the technology is on its way to demonstrating the potential to shoot down strategic threats.

Thanks to decades of fundamental research and a steady funding stream from a highly coordinated, defense-wide technology program launched in 2018, the Pentagon expects within the next year to:

- Procure the first 20-50-kW-class Enduring High-Energy Lasers (E-HEL) for the U.S. Army.

- Ramp up installations of the 60-150-kW High-Energy Laser with Integrated Optical-dazzler and Surveillance (Helios), made by Lockheed Martin on the Navy’s Arleigh Burke-class destroyers.

- Demonstrate a 1-megawatt-class laser made by nLight, which is capable of shooting down ballistic and hypersonic missiles.

But U.S.-made high-energy lasers are matched or even exceeded by allies and adversaries. Israel integrated the family of 20-100-kW-class Iron Beam lasers made by Rafael, and China paraded the CASIC LY-1 weaponized laser in September for the People’s Liberation Army Navy fleet, which appears to boast twice the aperture size of the Lockheed Helios.
