testing

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.”

TWZ reached out to Lockheed Martin, the prime contractor for HELIOS, for more information and was directed to comments from Navy Vice Adm. Brendan McLane at the Surface Navy Association’s (SNA) annual symposium in January. McLane is the commander of Naval Surface Force, U.S. Pacific Fleet. As the Navy’s top surface warfare officer, he is also often referred to by the title SWOBOSS.

“The Surface Navy has a rare opportunity with leadership aligned on delivering lethality, capability, and capacity at speed. As an enterprise, we must continue to think big as we develop the future platforms within the world. We must lay the foundations for the systems on those ships now so that they deliver on their promise to the American people,” McLane had said at the SNA conference. “Continued iteration with USS Preble’s HELIOS laser weapons system is another example of this. Last fall, successful at-sea testing paved the way for future laser weapons systems. We need to continue on this path. I am committed to advancing laser technology to the fleet. The dream of a laser on every ship can become a real one.”

TWZ has also reached out to the Navy for more information.

HELIOS, which also carries the designation Mk 5 Mod 0, is a 60-kilowatt-class laser directed energy weapon designed to be powerful enough to destroy or at least damage certain targets, such as drones or small boats. As its name indicates, it has a secondary function as a ‘dazzler’ to blind optical sensors and seekers, which could also be damaged or destroyed in the process. In the past, Lockheed Martin has talked about potentially scaling HELIOS’ power rating up to 150 kilowatts.

HELIOS has been integrated on Preble since 2022, and is currently the only Navy ship equipped with the system. Several other Arleigh Burke class destroyers have received lower-powered Optical Dazzling Interdictor (ODIN) laser systems. The Navy has installed more experimental high-energy laser directed energy weapons on other ships in the past.

Preble successfully downed at least one drone using HELIOS in a previous test in 2024. That milestone was disclosed in an annual report from the Pentagon’s Office of the Director of Operational Test and Evaluation (DOT&E) released in January 2025.

A multi-target scenario is a logical evolution in the demonstration of HELIOS’ capabilities. The Navy’s experiences during operations in and around the Red Sea in the past few years have underscored the challenges defenders face at sea and on land when responding to large volume drone attacks. Uncrewed aerial systems layered in with other threats like anti-ship ballistic and cruise missiles present even more complexities. The potential for traditional air defense capabilities to be overwhelmed is real. The level of complexity will only increase as artificial intelligence and machine learning-driven capabilities, including automated targeting and fully networked swarming, keep proliferating globally.

Laser directed energy weapons like HELIOS offer functionally unlimited magazine depth, as long as there is sufficient power and cooling capacity. As Lockheed Martin’s Taiclet noted last week, lasers also offer a way to conserve traditional surface-to-air missiles for use against targets that they might be better optimized against. That is particularly valuable for ships operating in areas where opportunities for rearming may be extremely limited and/or force them to leave their assigned station for an extended period of time.

This all presents cost benefits, too. As an example, the latest versions of the RIM-116 Rolling Airframe Missile (RAM), used for point defense on many Navy ships, each cost around $1 million.

Many warships across the Navy are also equipped with Mk 15 Phalanx Close-In Weapon Systems armed with six-barreled 20mm M61 Vulcan rotary cannons, but the ammunition for those weapons is not unlimited, either. Each Phalanx has enough ammunition to fire for a total of around 30 seconds, at most, at the lower of two rate-of-fire settings, before needing to be reloaded. Many ships across the Navy also have a mixture of other guns, including 5-inch or 57mm main guns, as well as 25mm or 30mm automatic cannons, all of which can also be used against close-in threats.

There are still significant questions about the demonstration last fall, including how rapidly the USS Preble was able to shift HELIOS from one target to another and how long it took each one to be effectively neutralized. The proximity of the drones to the ship and what kinds of profiles they were flying are also unknown.

A single laser can only engage one target at once. As the beam gets further away from the source, its power also drops, just as a result of it having to propagate through the atmosphere. This can be further compounded by the weather and other environmental factors like smoke and dust. More power is then needed to produce suitable effects at appreciable distances. Adaptive optics are used to help overcome atmospheric distortion to a degree. Altogether, laser directed energy weapons generally remain relatively short-range systems.

In addition, laser directed energy weapons, especially sensitive optics, present inherent reliability challenges for use in real-world military operations. Shipboard use adds rough sea states and saltwater exposure to the equation. There is also the matter of needing to keep everything properly cooled, which creates additional power generation and other demands.

Despite the hurdles, the U.S. Navy, as well as other navies globally, have continued to pursue laser directed energy weapons, as well as high-power microwaves, because of the capabilities they promise to offer in the face of an ever-expanding drone and missile threat ecosystem. HELIOS and ODIN both feature prominently in the design of the Navy’s future Trump class “battleships.” There has been talk already about the potential for expanding that directed energy arsenal to include lasers with megawatt-class power ratings.

“You know, we have continuous electron beam, free electron lasers today that can scale to megawatt-plus, gigawatt-plus [power ratings],” Navy Adm. Daryl Caudle, Chief of Naval Operations, told TWZ and other outlets at the Surface Navy Association’s (SNA) annual symposium last month. “I’m telling you that I don’t think a one-megawatt laser is beyond what should be on that battery [on the Trump class].”

Beyond the Trump class, “this is my goal, if it’s in line of sight of a ship, that the first solution that we’re using is directed energy,” Caudle also said. “Point defense needs to shift to directed energy. It has an infinite magazine.”

“What that does for me is it improves my loadout optimization, so that my loadout, my payload volume is optimized for offensive weapons,” the Navy’s top officer added. Furthermore, “as you increase power, the actual ability to actually engage and keep power on target, and the effectiveness of a laser just goes up.”

Challenges to the Navy’s directed energy future clearly still remain. In speaking last month, Caudle was optimistic for the future, but he has been open about difficulties in the past. At the SNA symposium in 2025, the admiral, then head of U.S. Fleet Forces Command, said he was “embarrassed” at the state of his service’s directed energy weapon developments.

“I am not content with the pace of directed energy weapons,” Vice Adm. McLane had also said back in 2024. “We must deliver on this promise that this technology gives us.”

This is reflective of broader difficulties that all branches have faced in the development and fielding of laser directed energy weapons, in particular, for use in the air and on the ground, as well as at sea, as you can read more about here.

What we do know is that the Navy continues to use the USS Preble to prove out the HELIOS system, including with the recently disclosed demonstration of its drone-zapping capabilities last fall.

The car has now passed all its impact tests, Vowles added, and drivers Carlos Sainz and Alex Albon “stand shoulder to shoulder with me”.

“They’re clearly, as I am, disappointed,” said Vowles.

“They want to be out there testing the car, and whilst they’re in our driver and loop simulator in tandem now, to increase that programme, it isn’t the same.”

Vowles said the main problem was the factory was unable to cope with the demand put on it by the car build process.

“It’s more of an output than anything else, of pushing not just the boundaries of design but the boundaries of just simply how many components can be pushed through the factory in a very short space of time,” said Vowles.

“The car we’ve built is about three times more complicated than anything we have put through our business beforehand.

“So, to put that in perspective, it means the amount of load going through our system is about three times what it used to be.

“And we started falling a little bit behind and late on parts. There are compromises you can make as a result of it.

“In addition to that, we have absolutely pushed the boundaries of what we’re doing in certain areas. And one of those is in certain corresponding tests that go with it.”

However, he said the team were on target to make it to the second pre-season test, which takes place in Bahrain on 11-13 February.

Vowles added: “We could have made Barcelona testing. Simple as that. But in doing so, I would have to turn upside down the impact on spares, components, and updates across Bahrain, [the first race in] Melbourne, and beyond.

“And the evaluation of it was that for running in a cold, damp Barcelona, against doing a (rig) test, against the spare situation, and frankly, there was zero points for running in a shakedown test, we made the decision, and I stand by it, that the right thing to do is to make sure we’re turning up at Bahrain, correctly prepared, and prepared in Melbourne as well.”

Vowles did not directly answer a question as to whether the car was significantly over the minimum weight limit, saying it was impossible to respond to “murmurings in the media” because it was not possible to know the answer until the car was assembled.

He also said he had “experts and specialists” working with Williams to try to improve their factory operations.

Seven of the 11 teams were running on Monday – Red Bull, Mercedes, Racing Bulls, Haas, Alpine and the new Audi and Cadillac teams.

McLaren said last week that they would not take their car on to the track until after day one as a result of trying to maximise design time. Ferrari, after an initial test at their factory last week, had also announced they would not run on Monday.

Aston Martin have said their new car will not be ready until Thursday, and Williams are missing the test entirely after delays to their design and production programme.

No times were issued, and all teams ran into at least some technical issues as they learned about their new cars.

Rival teams were impressed by the amount of mileage the two Red Bull teams managed considering it was the first full day of running with their new in-house engine, which has been developed in conjunction with new partner Ford.

Before the test started, McLaren and Red Bull revealed images of their 2026 cars for the first time.

McLaren, who won the drivers’ and constructors’ championship double last year for the first time since 1998, showed the car in the one-off testing livery it will run in this week.

Red Bull showed studio shots of their car, carefully chosen to disguise key design features.

Russell added: “We are pleased with our day, but I’ve also been impressed by several other teams.

“The Red Bull power unit has completed a lot of laps which, given that it’s their first engine they’ve built, means they’ve clearly done a good job.

“Haas also managed a similar amount of running to ourselves, so the Ferrari power unit has also put together plenty of mileage. It’s not quite how it was in 2014! The sport has evolved so much since then and the level, in every single aspect, is so high now.”

Audi have taken over the Sauber team for the German car company’s first entry into F1. They suffered a reliability issue that prevented Bortoleto driving in the afternoon.

Team principal Jonathan Wheatley said: “We had a technical issue, spotted it and decided to switch the car off. Plenty of testing this year and wanted to really understand the problems, see what the weather conditions are and decide whether we run tomorrow.”

Rain is forecast for Tuesday’s second day of the test, during which teams are permitted to run on a maximum of three of the available days.

Bortoleto said: “The cars are very different. I feel these are going to be slower but it’s very cool to have the power unit being 50% electric – you go out of the corner and you have so much speed being deployed and you can see how strong the engine is.

“You need to adapt but it’s still a racing car.”

Racing Bulls’ Lawson said: “[The car is] very different to drive and I haven’t got my head around it fully yet. We will keep learning. It feels like there is a lot more we can do as drivers to make a difference, potentially, but right now it’s very early days, very hard to know where we are for now just trying to optimise the car.

“[The power unit] feels good. But it’s very hard to tell – the main thing is reliability at the moment.

“We have done a good amount of laps today and the only issues we had today were safety precautions, not actual issues. But hard to know where we’re at compared to everyone else.”
