# US Navy's Laser Weapon Makes History in Drone Test HELIOS system successfully destroyed four drones at sea in a milestone demonstration. - **Source:** [TalkAndroid](https://brifing.si/source/ab08cf35-9595-489a-9848-b3b3b67ca5ca) - **Published:** 2026-08-02 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/cd75dc54-6141-432e-aec2-35166c090156 ## Historic Laser Test The USS Preble, an Arleigh Burke-class destroyer, successfully neutralized four drones at sea using Lockheed Martin's HELIOS directed-energy weapon. This test marks a technological milestone in countering the growing global threat posed by unmanned aerial vehicles to naval forces. Lockheed Martin CEO Jim Taiclet emphasized that the system preserves traditional anti-aircraft missiles for higher-priority threats. ## HELIOS Technical Specifications HELIOS (High-Energy Laser with Integrated Optical Dazzler and Surveillance) is a 60-kilowatt (approximately 80 horsepower) laser weapon system. Designated as Mk 5 Mod 0, it can disable small boats and drones while also functioning as a sensor-blinding device. Since 2022, HELIOS has been exclusively deployed on the USS Preble, distinguishing it from lower-powered ODIN systems on other Navy vessels. ## Naval Laser Revolution This demonstration is part of the US Navy's push to make directed-energy weapons a primary defense layer against drone threats. Recent operations in the Red Sea have shown how drone swarms can overwhelm conventional defense systems. Lasers offer the theoretical advantage of unlimited firing capacity as long as the ship provides sufficient power and cooling. ## Economic Comparison While a single RIM-116 Rolling Airframe Missile costs approximately $1 million, laser systems have significantly lower per-shot costs. However, the initial investment for laser technology remains substantial. This economic equation will play a crucial role in shaping the Navy's future defense budgeting decisions. ## Technological Limitations Current HELIOS versions can only engage one target at a time and are affected by weather conditions (fog, dust, saltwater spray). Performance details such as target-switching speed and neutralization time per drone haven't been fully disclosed, raising operational concerns. ## Challenging Maritime Conditions Operating laser systems in rough seas with saltwater spray and managing their intensive cooling requirements present significant deployment challenges. Effectiveness decreases with range, meaning lasers may only be viable for close-range defense scenarios in current configurations. ## Future Projections The US Navy aims to widely deploy laser weapons across its fleet, but current technological constraints may delay these plans. Improvements in power capacity and targeting systems will be critical over the next five years. Military experts recommend integrating lasers with traditional weapons in a layered defense network. ## Awaiting Combat Validation Despite the USS Preble's successful test, HELIOS's effectiveness in unpredictable combat conditions against drone swarms and electronic warfare environments remains unproven. The Navy requires more operational experience to fully evaluate the system. This test represents a promising yet cautious step toward the future of directed-energy weapons. ## Sources covering this story - https://www.talkandroid.com/528863-us-navys-laser-weapon-destroys-drones-in-historic-testbut-is-the-hype-justified-87321/ — --- _Summary written by Brifing from the original reporting.
