USS Preble Used HELIOS Laser to Zap Four Drones in Expanding Testing
3rd February 2026
The U.S. Navy’s Arleigh Burke class destroyer USS Preble used its High-Energy Laser with Integrated Optical Dazzler and Surveillance (HELIOS) system to down four drones in a demonstration last year, Lockheed Martin has shared. Earlier this month, the Navy’s top officer said his goal is for directed energy weapons to become the go-to choice for warship crews when it comes to defending against close-in threats. However, the service has continued to face significant hurdles in fielding operational laser weapon systems.
“Speaking of amazing technology, we successfully used a shipboard laser system, Lockheed Martin’s HELIOS, to knock an incoming UAV [uncrewed aerial vehicle] right out of the sky,” the company’s CEO Jim Taiclet said during a quarterly earnings call last week. “The HELIOS weapon system successfully neutralized four drone threats in a U.S. Navy-operated counter-UAS [uncrewed aerial systems] demonstration at sea, showcasing an opportunity to eliminate drone attacks using lasers, and saving U.S. and allied air defense missiles for more advanced threats.”
