Raytheon Intelligence & Space (RI&S), a Raytheon Technologies business, delivered the next high-energy laser weapon system to the U.S. Air Force. It will be deployed overseas for operator training and experimental testing and evaluation. Following the completion of the Directed Energy Weapon Initial Operational Employment Review and Approval Process, High Energy Laser Weapon System (HELWS) is now certified for use in combat.
«HELWS builds directly on the feedback we received from operators in the field», said Annabel Flores, vice president of Electronic Warfare Systems at RI&S. «We’ve made the system more rugged. We improved its accuracy and overall efficiency based on real-world lessons learned in an operational environment».
This system features a number of improvements, including ruggedized enhancements to ensure transportability and survivability in a wide range of operational environments; a new beam director for more accurate targeting; and a robust power system for additional magazine depth – the ability to fire the laser for a longer period of time.
«You can take down dozens of drones on a single charge», said Flores. «And if you are plugged into a generator, you have deep, rechargeable magazines».
Mounted on a Polaris MRZR all-terrain vehicle, HELWS uses a variant of RI&S’ Multi-spectral Targeting System, an electro-optical/infrared sensor that detects, identifies and tracks unmanned aerial threats.
A prior version of HELWS was deployed in a forward operating environment earlier this year and recently passed 1,000 hours of operations. RI&S is contracted to deliver another further improved system to the Air Force later this year.
Raytheon Company delivered the first High-Energy Laser Counter-Unmanned Aerial System (UAS) to the U.S. Air Force earlier this month. The system will be deployed overseas as part of a year-long Air Force experiment to train operators and test the system’s effectiveness in real-world conditions.
Raytheon’s High-Energy Laser Weapon System (HELWS) uses an advanced variant of the company’s Multi-spectral Targeting System, an electro-optical/infrared sensor, to detect, identify and track rogue drones. Once targeted, the system engages the threat, neutralizing the UAS in a matter of seconds.
«Five years ago, few people worried about the drone threat», said Roy Azevedo, president of Raytheon Space and Airborne Systems. «Now, we hear about attacks or incursions all the time. Our customers saw this coming and asked us to develop a ready-now counter-UAS capability. We did just that by going from the drawing board to delivery in less than 24 months».
Raytheon installed its high-energy laser weapon system on a small all-terrain vehicle. On a single charge from a standard 220-volt outlet, the HELWS can deliver intelligence, surveillance and reconnaissance capability and dozens of precise laser shots. It can also be paired with a generator to provide a nearly infinite number of shots.
Raytheon Company is integrating multiple proven technologies to counter the unmanned aerial system threat across a wide range of scenarios – from commercial airports to forward operating bases to crowded stadiums. Raytheon’s portfolio of sensors, command and control systems, and kinetic and non-kinetic effectors covers all aspects of the UAS threat.
Raytheon’s High-Energy Laser Weapon System Counters UAS Threats
Raytheon Company will deploy two prototype high energy laser weapon systems to troops overseas under a U.S. Air Force contract. The Air Force experimentation includes 12 months of in-field operation against unmanned aerial systems and operator training.
Raytheon’s High-Energy Laser Weapon System (HELWS) uses pure energy to detect, identify and instantly take down drones. It can target a single drone with precision. The HELWS is paired with Raytheon’s Multi-spectral Targeting System. It uses invisible beams of light to defeat hostile Unmanned Aircraft Systems (UASs). Mounted on a Polaris MRZR all-terrain vehicle, the system detects, identifies, tracks and engages drones.
«Every day, there’s another story about a rogue drone incident», said Stefan Baur, vice president of Raytheon Electronic Warfare Systems. «These threats aren’t going away, and in many instances, shooting them with a high energy laser weapon system is the most effective and safest way to bring them down».
The contract follows successful demonstrations of Raytheon’s directed energy systems for the Air Force and the U.S. Army.
Raytheon’s sophisticated MTS sensor package, combined with a high-energy laser and mounted on the MRZR vehicle, could offer an effective defense against UAVs.
In a windowless room on Raytheon’s campus in McKinney, Texas, a small team of blue jean-clad engineers and physicists is doing something that’s never been done before. They move back and forth between computer screens and a vehicle that looks like it’s straight out of Mad Max.
«Basically, we’re putting a laser on a dune buggy to knock drones out of the sky», said Doctor Ben Allison, director of Raytheon’s high energy laser product line.
It’s actually a little more complicated than that, Allison added. The team is combining a high energy laser with an advanced variant of Raytheon’s Multi-spectral Targeting System – a sophisticated package of electro-optical and infrared sensors – and installing it on a Polaris MRZR, a small, all-terrain vehicle.
In an homage to Austin Powers, Art Morrish, vice president of Advanced Concepts and Technology at Raytheon Space and Airborne Systems, said, «It’s not sharks with laser beams on them, but it’s pretty close».
A defense against drones
According to Allison, the idea grew out of a meeting with Raytheon’s CEO and Chairman Tom Kennedy earlier this year. Kennedy told Allison and Morrish that an allied nation had recently used a Patriot missile to shoot down a cheap, store-bought UAS that was outfitted with a grenade-like munition.
«That cost-to-kill ratio is high», explained Allison, «but the threat is clear. So, the question became, ‘What can we do for a counter-UAS system using a high-energy laser and do it quickly. We didn’t want to go out and do a bunch of research and development. We wanted to take the assets and capabilities Raytheon has today and use them to really affect this asymmetrical threat. We settled on a small system that’s hugely capable».
Good Things Come in Small Packages
The team first looked at putting its laser on a standard-size military container, but soon realized it only took up a quarter of the available space. At the same time, an undisclosed customer was exploring ways to put a laser weapon system on vehicles small enough to fit in an airplane’s cargo bay or inside a helicopter.
«When we saw how small we could make it and we saw a clear customer need, we immediately wanted to find a very tactically relevant vehicle that could get out to forward operating bases and do its mission», said Allison.
The system is standalone, with a footprint of roughly 30 square feet/2.79 square meter. On a single charge from a standard 220v outlet, the same kind you plug your washing machine into at home, the HEL system onboard the MRZR delivers four hours of intelligence, surveillance and reconnaissance capability and 20 to 30 laser shots. The system can also be coupled with a generator to provide virtually infinite magazine depth.
While the laser and the vehicle are sure to draw all the attention, it’s the weaponized MTS sensor package that is the core of the system. In this configuration, the MTS provides its standard setting ISR and tracking capabilities while also serving as a beam director.
That’s something Allison says sets this combo apart from bigger, more power-hungry systems. «If you have a good beam director, then you can use a smaller, more efficient laser. You can make your system smaller and more flexible», said Allison.
Hitting the Road
Morrish believes the solution is particularly suited for expeditionary missions. «Right now, it’s a shoot-on-the-halt capability», said Morrish. «You drive the vehicle wherever you’re going to drive it. You stop and then you fire up the laser. That makes it great for protecting forward-operating bases and places where convoys have to stop. The next step is to set it up so you can actually shoot on the move».
Raytheon began field testing the HELWS MRZR last week and is slated to demonstrate it at the U.S. Army’s Maneuver Fires Experiment at Fort Sill, Oklahoma, in December.
«The idea is to quickly take this solution out of the lab and put it in the hands of the operators», said Morrish. «The folks in uniform are going to find ways to use it that those of us in lab coats never have».
