HELWS belongs to the same counter-UAS (C-UAS) category as radio-frequency jammers and interceptor drones, but it is one of a small number of systems in that category that kills a target with light rather than a projectile or a signal.¹ The laser weapon itself has been treated by the United States as a genuine, near-term air-base-defense tool rather than a laboratory curiosity, moving from a 2019 prototype contract to overseas operational testing within about six months and later to demonstrations for the United Kingdom's Ministry of Defence.^2,4

Development moved quickly by defense-program standards. The Air Force Research Laboratory awarded Raytheon a $23.8 million contract in 2019 for two prototypes, followed by a further $13.1 million for a third, and Raytheon has stated it received at least $52.4 million in total Department of Defense funding to develop and deliver HELWS units.^2,5 The U.S. Air Force accepted its first HELWS in October 2019 and had a unit forward-deployed for operational assessment within months, a pace unusual for a directed-energy weapon.^2,6

Raytheon's corporate identity changed partway through HELWS's life. Raytheon Company merged with United Technologies in 2020 to form Raytheon Technologies, which renamed itself RTX in 2023, so recent HELWS press material is issued under the RTX name even though the weapon itself still carries the original Raytheon brand.¹ That corporate history matters less to an encyclopedia entry than what the hardware actually does, and the sections below cover how HELWS works, where it has been tested and fielded, how it compares with Raytheon's own larger laser programs, and what remains genuinely unknown about its combat record.

The Raytheon HELWS pairs a solid-state fiber laser, rated at roughly 10 kilowatts in its baseline Air Force configuration (some Raytheon materials describe the broader HELWS product line as scalable up to 15kW-class), with an MTS electro-optical/infrared sensor turret borrowed from Raytheon's own reconnaissance-pod business.^1,3 That sensor does double duty, it finds and classifies the target, then serves as the aim-point for the beam itself, so HELWS does not need a separate fire-control radar of its own to engage a target it can already see optically.³ Raytheon quotes an engagement range around 3 kilometers against small drones, with a beam dwell time of roughly five seconds needed to disable a typical commercial quadcopter, and closer to 8-10 seconds for a confirmed kill depending on the target's construction and where the beam lands.^4,7

Power and logistics were deliberately kept simple. A HELWS unit can run off a standard 220-volt outlet or a field generator, and Raytheon has said a single charge is enough for around four hours of surveillance work and 20-30 laser shots, a very different logistics footprint from a missile interceptor that has to be re-armed round by round.^5,7 An operator fires the weapon from a laptop-based console with a game-style controller, watching a split-screen display of the wide-angle and narrow-tracking camera feeds, which lets a single crew member run detection, tracking and engagement without a dedicated fire-control team.⁵

HELWS's real design achievement is not the laser itself so much as how little vehicle it needs. Raytheon has shown the system mounted on a Polaris MRZR dune buggy, on the bed of a civilian F-150 pickup truck, and, most recently, integrated onto a British Army Wolfhound armored vehicle, without a fundamentally different laser or sensor package each time.^8,9 That platform-agnostic packaging is a deliberate answer to the biggest historical criticism of high-energy laser weapons, that they are too large, too power-hungry and too fragile to leave a test range, and it is the feature Raytheon leans on hardest when pitching HELWS for new roles.⁹

Raytheon's HELWS program grew out of the Air Force Research Laboratory's push, in the late 2010s, to get a directed-energy counter-drone weapon out of the laboratory and into an expeditionary environment rather than treating lasers as a decades-away technology. AFRL's October 2019 contract, worth $23.8 million for two prototype units plus a follow-on $13.1 million for a third, was explicitly framed around rapid field testing rather than a traditional multi-year acquisition cycle.^2,6 Trade press at the time nicknamed the buggy-mounted prototype the Mad Max laser, a label that stuck because it captured how unlike a conventional weapons program the vehicle looked.³

The second-generation prototype, referred to in Raytheon and Air Force material as HELWS2, began overseas testing in September 2020, and by the following year the fleet of Polaris MRZR-mounted units had logged more than 9,000 hours of combined operator training and operational assessment.⁶ In April 2021, the Air Force awarded Raytheon a further $15.5 million to upgrade the design, incorporating lessons from that overseas experience into a more ruggedized, more powerful successor configuration.⁶ Raytheon has since said publicly that HELWS's cumulative operational hours passed 25,000, and that a broader cumulative testing-and-training total (spanning training ranges as well as forward locations) has passed 40,000 hours with more than 400 targets downed, though the company has not broken that combined figure down by year or location.^1,9

Integration testing accelerated after the initial overseas deployments. On March 31, 2022, Raytheon paired a HELWS unit with the NASAMS (National Advanced Surface-to-Air Missile System) air-defense network, jointly developed by Raytheon and Kongsberg Defence & Aerospace of Norway, at White Sands Missile Range, New Mexico. The laser took automated targeting cues from NASAMS's Sentinel radar and Fire Distribution Center and destroyed nine Group 1 and Group 2 drones in front of U.S. military and allied observers, demonstrating that HELWS could act as a low-cost effector plugged into an existing, already-fielded air-defense command network rather than needing its own dedicated radar.⁷

British interest followed a similar arc. In July 2024, Raytheon UK, the Defence Science and Technology Laboratory (Dstl) and Defence Equipment and Support fired a HELWS unit at full power while mounted on a British Army Wolfhound armored vehicle at Dstl's Porton Down test range, the first time a high-energy laser weapon had been fired from a land vehicle in the UK.⁸ Five months later, in December 2024, British Army soldiers rather than contractor personnel operated the same HELWS-on-Wolfhound setup against moving aerial targets, under the joint UK-industry Team Hersa enterprise and the Land Laser Directed Energy Weapon (LDEW) demonstrator programme, alongside partners including Blighter Surveillance Systems.⁹

No independently confirmed combat engagement or drone kill by a HELWS unit has been made public as of mid-2026. What is publicly documented is that the Air Force certified HELWS for combat use and moved multiple units into CENTCOM-area forward operating locations beginning in 2020, explicitly to protect air bases against the kind of small-drone surveillance and harassment threat that had already been observed against U.S. and allied installations in the Middle East.^1,6 Raytheon and Air Force statements describe the deployment in general terms, as operator training and operational assessment in an active theater, rather than naming a specific base or citing a specific engagement, and no news organization has independently reported a HELWS shootdown by name.⁶

That gap between certified for combat, deployed to an active theater and documented combat kill is worth stating plainly rather than papering over. Small-drone threats against U.S. and coalition bases in Iraq, Syria and the wider Gulf region became a serious and repeated problem from 2020 onward, which is precisely the environment HELWS was built and funded to address, but Raytheon's own public statements about HELWS's record, tens of thousands of operational hours, hundreds of targets downed, do not distinguish between training-range totals and any real-world intercepts, and neither the company nor the Department of Defense has published a breakdown.^1,9 Readers should treat certified for combat use and used in combat as two different claims until a specific, source-backed engagement surfaces.

The most concrete illustration of that threat class is not a HELWS engagement at all. On 28 January 2024, an Iranian-backed militia drone struck Tower 22, a U.S. outpost in Jordan, killing three soldiers, the kind of low, slow, hard-to-detect quadcopter-class threat HELWS was funded to defeat.¹⁶ A subsequent Army investigation found the outpost's counter-drone defenses inadequate at the time of the attack, and no source reviewed for this article places a HELWS unit at Tower 22 specifically, since HELWS is an Air Force program and Tower 22 was an Army-run site, but the incident is widely cited in later U.S. base-defense planning as the reason forward outposts across the region moved to add layered counter-drone coverage.¹⁷

Raytheon has not given HELWS's evolving hardware a family of separate product names the way it has with some other programs. Instead, the system has moved through numbered internal generations, the original prototype, followed by the ruggedized HELWS2 configuration tested overseas from September 2020, and a further upgrade funded by the Air Force's April 2021 contract, each iteration keeping the same 10-kilowatt-class laser and MTS sensor core while improving durability, power management and ease of maintenance in the field.⁶

The clearest variation is platform, not laser power. The same HELWS payload has been shown on a Polaris MRZR dune buggy (the original Air Force configuration), on the bed of an unmodified civilian F-150 pickup truck, and integrated onto a British Army Wolfhound armored vehicle for the UK's LDEW demonstrator programme.^8,9 As of 2025, Raytheon has said it is developing a palletized version intended for even faster cross-platform integration, and is in discussions about a roll-on/roll-off configuration for naval vessels, extending HELWS beyond the land-vehicle role it was originally built for.¹⁰

Raytheon also builds a considerably larger, distinct laser program that is sometimes confused with HELWS because it shares a manufacturer and a mission set. The Directed Energy Maneuver Short-Range Air Defense system (DE M-SHORAD, built around what the Army calls the Multi-Mission High Energy Laser, or MMHEL) mounts a 50-kilowatt-class laser, roughly five times HELWS's power, on an eight-wheeled Stryker combat vehicle, with Kord Technologies handling power management, cooling and the Ku720 tracking radar integration.^11,12 DE M-SHORAD is designed to defeat rockets, artillery and mortar rounds as well as drones, a heavier-threat mission HELWS was never intended for, and four DE M-SHORAD prototypes were sent to the Middle East for Army soldier testing in February 2024, with early feedback described by defense reporters as mixed rather than an unqualified success.^13,14 The two programs are best understood as siblings built for different weight classes of threat rather than as the same weapon under two names.

The United States Air Force is HELWS's confirmed and best-documented operator, having accepted its first unit in October 2019, certified the system for combat use, and deployed multiple HELWS units to overseas operational locations from 2020 onward as part of an ongoing base-defense experimentation campaign.^2,6 The Air Force Research Laboratory continued to fund upgrades through at least 2021, and Raytheon's later public statements describe multiple additional systems as being in theater by the mid-2020s, though the company has not disclosed a specific fleet size.^1,6

The United Kingdom is HELWS's most advanced evaluation customer rather than a confirmed operator. Raytheon UK, the Ministry of Defence's Defence Science and Technology Laboratory, Defence Equipment and Support and the joint Team Hersa enterprise have run two rounds of live-fire trials, in July and December 2024, culminating in British Army soldiers themselves firing a Wolfhound-mounted HELWS at moving aerial targets, but no UK procurement contract for HELWS had been publicly announced as of mid-2026.^8,9 Those trials sit under the UK's broader Land Laser Directed Energy Weapon demonstrator programme, alongside British industry partners Frazer-Nash, NP Aerospace, LumOptica, Blighter Surveillance Systems and Cambridge Pixel.⁹

HELWS and Raytheon's own DE M-SHORAD are the clearest comparison because they come from the same company and the same underlying push to field laser weapons quickly, yet they sit at opposite ends of a deliberate power-and-weight tradeoff. HELWS's roughly 10-kilowatt laser and buggy-scale footprint buy speed of deployment and cost (it reached an overseas base within about six months of its first Air Force contract), while DE M-SHORAD's 50-kilowatt-class laser needs a full Stryker combat vehicle and years longer in development to reach even a limited soldier-touch prototype stage.^2,13 That tradeoff maps directly onto what each system is meant to kill. HELWS is sized for small hobbyist-class drones, while DE M-SHORAD's added power is meant to reach rockets, artillery shells and mortar rounds, threats a 10-kilowatt beam cannot reliably defeat in the available engagement window.

Set against non-laser rivals in the same C-UAS category, HELWS's appeal is less raw performance than logistics. A directional radio-frequency jammer can be lighter and cheaper still, but it does nothing against a drone flying a pre-programmed route with no live radio link back to an operator, a gap a laser does not have since it does not depend on the target's own electronics at all.¹ Conversely, a kinetic interceptor, whether a missile, a net-firing gun or another drone, destroys its target in a single shot but has to be re-armed round by round, where HELWS's main constraint is simply how much electrical power and cooling capacity it has on hand. That tradeoff, near-unlimited magazine against a hard cap on power and weather sensitivity, is the argument Raytheon has consistently made for HELWS since its first overseas deployment, and it is also the argument competitors in higher-power laser and microwave counter-drone programs are now making against HELWS itself as those programs mature.

What is the Raytheon HELWS laser weapon system? HELWS (High Energy Laser Weapon System) is a vehicle-mounted, roughly 10-kilowatt solid-state laser built by Raytheon to detect, track and disable small drones at ranges up to about 3 kilometers, first fielded by the U.S. Air Force in 2019.^1,2

How does the Raytheon HELWS shoot down drones? HELWS uses an electro-optical/infrared sensor turret to find and track a target, then holds a focused laser beam on it for roughly five to ten seconds until heat damage disables the drone's flight controls or airframe, all controlled by a single operator using a laptop and game-style controller.^3,5

What is the range of the HELWS laser? Raytheon quotes an effective engagement range of about 3 kilometers against small commercial-class drones, though like any high-energy laser, that figure degrades in rain, fog, dust or smoke.^4,15

How much does the Raytheon HELWS cost? Raytheon has disclosed cumulative Air Force development and delivery contracts of at least $52.4 million, but has not published a per-unit price for a production HELWS system.^2,5

Is Raytheon HELWS still in service? Yes. The U.S. Air Force has certified HELWS for combat use and continues to operate multiple units at overseas locations for base-defense missions, and the United Kingdom has run live-fire evaluations of a vehicle-mounted HELWS as recently as December 2024.^1,9

What is the difference between HELWS and DE M-SHORAD? Both are Raytheon-linked laser programs, but HELWS is a lighter, roughly 10-kilowatt system built for small drones and quick deployment on a buggy or truck, while DE M-SHORAD (built around the Multi-Mission High Energy Laser) is a 50-kilowatt-class laser on a Stryker combat vehicle meant to also defeat rockets, artillery and mortar fire.^11,13
