U.S. Military Deploys ‘Invisible’ Laser Weapons Against Iranian Drones in Strait of Hormuz
The U.S. military is using high-energy laser weapons in the Strait of Hormuz to destroy Iranian drones and other airborne threats, marking a significant battlefield deployment of technology that the Pentagon has spent decades trying to transform from experimental systems into practical weapons of war, according to a new report.
The laser systems are being used against Iranian military hardware, including attack drones, amid the continuing confrontation in and around the strategic waterway. Unlike the bright beams associated with science fiction, the military’s high-energy infrared lasers are invisible to the human eye. They work by concentrating energy on a precise point of a target until critical components are damaged or destroyed.
The technology offers the U.S. military a particularly important advantage against relatively inexpensive Iranian drones: cost. Traditional air-defense missiles can cost millions of dollars per interceptor, creating a major imbalance when they are fired at drones costing a small fraction of that amount. Laser systems, by contrast, rely primarily on electrical power and can engage targets at a dramatically lower cost per shot. The Defense Department says directed-energy systems can be used against drones and incoming cruise missiles “at a much lower cost than using more expensive kinetic weapons like missiles.”
“We can very specifically track and target drones and put the spot exactly where we want it, [in order] to disable its sensors or kill [i.e. explode] the drone itself,” Mark Neice, president of Directed Energy Consultants, which works with the military, told the New York Post.
Laser weapons generally draw electricity from generators, batteries or a platform’s power system and convert that energy into a highly concentrated beam. Unlike conventional guns or missile launchers, they do not depend on a limited supply of physical ammunition, although their effectiveness can be affected by available power, cooling requirements, atmospheric conditions and the ability to maintain a precise line of sight to a target.
The technology has advanced significantly in recent years. The Pentagon has moved beyond treating directed-energy weapons primarily as research projects and is now preparing to field them on a much larger scale. Earlier this month, the Army awarded AeroVironment a $464.8 million contract for its Enduring-High Energy Laser program, the first U.S. Army production contract for a high-energy laser weapon system. The company is expected to supply dozens of LOCUST X3 systems over the coming years.
The LOCUST system has already emerged as one of the most operationally experienced lasers in the American arsenal. The technology has been deployed overseas since 2022 and has also been integrated onto Army vehicles.
One unusual feature of some of the military’s directed-energy systems is the way operators control them: modified video-game-style controllers are used to make the weapons relatively intuitive for troops.
“If you’ve shot a Spartan laser in ‘Halo’, you can probably fire [one of the cutting-edge weapons] in real life,” Jared Keller, a military technology journalist and author of the Laser Wars newsletter, told the New York Post.
Secretary of War Pete Hegseth received a firsthand look at the technology during a June visit to White Sands Missile Range in New Mexico, where the Pentagon demonstrated several high-energy laser and high-power microwave weapons. The demonstration included systems ranging from a 20-kilowatt LOCUST weapon to a 300-kilowatt Lockheed Martin system known as Valkyrie.
“Secretary Hegseth was able to take over a controller and shoot down a drone with, I think, a couple minutes of training,” Keller reportedly told the outlet.
Hegseth later said he watched “incoming drones and cruise missiles” get stopped “dead in their tracks.”
The Pentagon is now preparing for a major expansion of the technology. Hegseth told Congress earlier this year that the military intends to acquire “tens to hundreds” of directed-energy weapons, while the Trump administration’s fiscal 2027 budget proposal includes more than $2 billion for directed-energy research, development and testing.
The Navy, meanwhile, is pushing toward the eventual deployment of laser weapons across its fleet. Chief of Naval Operations Adm. Daryl Caudle said this week that directed energy could allow American warships to reserve their limited and expensive missile inventories for more dangerous threats while using electrical power to defeat drones and other lower-cost weapons.
“I don’t view directed energy as a replacement for kinetic weapons. I view it as an essential part of a layered defense that can fundamentally change our magazine-depth problem,” Caudle said.
“That changes both the economics and endurance of naval combat and allows us to preserve our most capable kinetic weapons for the threats that demand them.”
The reported use of laser weapons in the Strait of Hormuz comes as the strategically critical shipping route remains at the center of the confrontation with Iran. Tehran has restricted passage through the strait, while U.S. forces have sought to keep oil tankers and other shipping moving through the waterway. Iran has also continued employing drones and other weapons against vessels and American forces operating in the region.
For the Pentagon, the fighting is providing a real-world test of a technology pursued by the U.S. military for roughly half a century. After decades in which laser weapons repeatedly appeared to be on the verge of battlefield deployment, military leaders now say the underlying science has largely been solved and that the primary challenge is producing reliable systems in large numbers and integrating them into ships, vehicles and existing air-defense networks.
