Chinese military scientists claim to have achieved a ‘huge breakthrough’ on laser weapon technology

- High-energy laser weapons can now operate ‘infinitely’ thanks to a new cooling system that completely eliminates the build-up of waste heat
- The technology could significantly change the face of battle by extending engagement times, and increasing range and damage, researchers say

Published: 5:00pm, 11 Aug, 2023

Chinese military scientists have announced a major breakthrough in laser weapon technology, claiming they have developed a new cooling system that allows high-energy lasers to operate “infinitely” without any build-up of waste heat.

According to scientists at the National University of Defence Technology, in Changsha, Hunan province, the new cooling system completely eliminates the harmful heat that is generated during the operation of high-energy lasers. The issue has been a major technical challenge for laser weapon development.

With the new technology, weapons can now generate laser beams for as long as they want, without any interruption or degradation in performance.

Lockheed Scaling Army Combat Laser to Cruise Missile Destroying 500 Kilowatts
August 13, 2023 by Brian Wang

Lockheed Martin will scale its combat laser technology to a 500 kW-class laser. It will be the most powerful laser Lockheed Martin has produced, topping its 300 kW-class laser power level developed under a contract from the Department of Defense’s Office of the Under Secretary of Defense for Research & Engineering, OUSD (R&E). The 500 kW-class laser, developed under a new contract just awarded by OUSD (R&E), is the second phase of the High Energy Laser Scaling Initiative (HELSI).

The U.S. Army is working through a variety of challenges with directed-energy weapons for air defense, including how to affordably manufacture the high-tech capability and sustain it on the battlefield.

German Navy completes successful sea trials of 100-kW laser weapon
By David Szondy
September 26, 2023

Laser weapons have begun to spread throughout NATO, as the German Navy has completed a year-long trial under realistic sea conditions of a 20-kW MBDA Deutschland/Rheinmetall Laser Weapon Demonstrator. It was installed aboard the 5,800-tonne (6,393-ton) frigate Sachsen.

Organized by the Federal Office of Bundeswehr Equipment, Information Technology and In-Service Support (BAAINBw), the trials were carried out by the High-Energy Laser Naval Demonstrator Working Group (ARGE) consisting of MBDA Deutschland and Rheinmetall.

In June 2022, a modular laser weapon system was installed on the deck of the Sachsen and integrated into the warship's command and control system. The weapon is made up of 12 2-kW laser modules based on coiled bundles of solid-state doped fiber, which generate high-quality laser beams. These go through a beam combiner that uses spectral coupling technology to form a single, much more powerful beam that can be scaled up to 100 kW.

Realistically, I think particle-energy weapons will become ubiquotous until at least the 2040's. I'm basing my guess off of how nuclear bombs were invented in the 1940's.

Raytheon to build microwave weapon antennas for US Air Force and Navy
By David Szondy
December 28, 2023

https://newatlas.com/military/raytheon- ... orce-navy/
The US Navy and US Air Force have tapped Raytheon to design, build and test two high-power microwave antenna systems. These will be used in field-grade directed energy weapons to counter aerial drones and similar threats.

Recent conflicts have dramatically shown the increasing role that drones play in modern warfare. Even a small quadcopter of the sort you can buy in a hobby shop can be easily repurposed as a reconnaissance platform for artillery, or even as a way of delivering hand grenades with deadly precision. Add to this the specially made military drones of various sizes and levels of sophistication, and you end up with a formidable force that can be deployed in shocking numbers.

To counter this threat, scientists and engineers have come up with a number of approaches. One of the most promising is the use of directed energy weapons that use lasers and microwaves to disrupt or destroy hostile drones. The beauty of such systems is that, if they work, they can operate with unlimited ammunition that costs a dollar a shot and travel at the speed of light. The weapons can also be programmed to cover large areas of the sky while sparing friendly aircraft.

Under a three-year US$31.3 million contract from the Naval Surface Warfare Center Dahlgren Division, Raytheon is tasked with developing prototype antenna systems by 2026 as part of the Directed Energy Front-line Electromagnetic Neutralization and Defeat (DEFEND) program.

Air defense for $13 a shot? How lasers could revolutionize the way militaries counter enemy missiles and drones
By Brad Lendon, CNN

Updated 12:08 AM EDT, Thu March 14, 2024

Britain this week showed off a new laser weapon that its military says could deliver lethal missile or aircraft defense at around $13 a shot, potentially saving tens of millions of dollars over the cost of missile interceptors that do the job now.

Newly released video of a test of what the United Kingdom’s Defense Ministry calls the DragonFire, a laser directed energy weapon (LDEW) system, captured what the ministry says was the successful use of the laser against an aerial target during a January demonstration in Scotland.

“It’s a potential game changer for air defense,” the video says as a bright laser beam pierces the night sky over a firing range in the remote Hebrides archipelago, creating a ball of light as it hits its target.

DragonFire: UK laser could be used against Russian drones on Ukraine front line

27 minutes ago

A UK high-power laser weapon could be sent to Ukraine to take down Russian drones, the defence secretary says.

According to Grant Shapps, the weapon could have "huge ramifications" for the conflict in Europe.

The DragonFire weapon is expected to be rolled out by 2027, but Mr Shapps said he wanted to "speed up" production and make it available sooner.

It follows a successful trial of the laser, carried out against an aerial target for the first time in January.

The laser was originally expected to be operational by 2032, but new reforms intended to speed up government procurement of weapons mean that it will now be ready five years earlier.

Directed energy weapon replaces million-dollar missiles at 13 cents a shot
By David Szondy
May 15, 2024

A new directed energy weapon is being rolled out to bolster British defense capabilities. And, at 13 cents a shot, it's just as effective, but a lot cheaper than the multi-million dollar missiles it's designed to replace.

The Radio Frequency Directed Energy Weapon (RFDEW) is part of the British government's policy to respond to a changing geopolitical situation, placing the country's defense on more of a war footing as it increases spending to 2.5% of GDP by 2030. This policy change also includes fast-tracking the rollout of lasers and other directed energy weapons.

The latter is extremely important, because, well, knocking out a drone that costs a few grand with a missile costing millions of dollars per round is bad economics – see, for example, the US$1.3-2.5 million Sea Viper missile used to take out a US$20,000 drone, as reported by Navy Lookout. Also, missile stockpiles tend to be pretty small, and swarms of cheap drones could easily exhaust them.

Advanced laser weapon field tests conducted on army vehicle
By David Szondy
July 23, 2024

In another step toward practical battlefield energy weapons, the UK has for the first time tested a laser weapon mounted on a British Army Wolfhound armored vehicle as part of the Land Laser Directed Energy Weapon (LDEW) Demonstrator program.

Ever since they were invented in the 1960s, lasers have been seen as a potentially game-changing weapon. At first, it makes perfect sense. Lasers can cut through steel. They move at the speed of light. They can engage multiple targets instantly. The rounds are potentially infinite and cost surprisingly little.

The problem has been figuring out how to move lasers off the workbench and onto the battlefield. A practical laser weapon has to be powerful enough to significantly damage a target. It needs to be able to lock onto targets long enough to complete the job. The system needs to be able to adjust the beam so it remains focused and can compensate for atmospheric distortion, fog, dust, and other factors. It also needs to be portable, robust, and compact.

US Navy Destroyer Fires 60 KW Helios Combat Laser
February 2, 2025 by Brian Wang

The US Navy released a new photo of USS Preble (DDG-88) firing her HELIOS laser weapon.



The USS Preble is the first U.S. Navy vessel equipped with HELIOS, a 60-kilowatt-class directed energy laser weapon developed by Lockheed Martin. It is also the first laser weapon integrated with the Aegis combat system, a key feature that enhances the ship’s ability to track, engage, and neutralize threats.

It provides a cost-effective countermeasure against drones, small boats, and other asymmetric threats. The U.S. Navy has been expanding its directed energy arsenal.

British Army energy weapon blasts drones by the swarm
By David Szondy
April 16, 2025

https://newatlas.com/military/british-a ... nes-swarm/
The British Army has successfully tested a Radiofrequency Directed Energy Weapon (RF DEW) that took out multiple swarms of drones simultaneously and near instantaneously using high-frequency radio waves at a cost of 10p (US$0.13) per shot.
Drones are becoming a major factor in modern warfare as well as a growing potential hazard to civilian air traffic. In 2024 alone, Russia launched 18,000 drone attacks against Ukraine and the Bard College's Center for the Study of the Drone claims that there were 241 near collisions between drones and civilian aircraft last year in the US alone.

The problem with drones is that many variants are very small and cheap and can be launched in swarms that could potentially overwhelm or evade conventional air defense systems. One approach to countering these swarms is to use directed energy weapons to attack all the intruders at once instead of one at a time.

Japan shows off electromagnetic railgun for blasting hypersonic missiles
By David Szondy
April 23, 2025
https://newatlas.com/military/japan-ele ... -missiles/

Looking like something out of Minecraft, the Japan Maritime Self-Defense Force has released a new image of its latest electromagnetic railgun being developed by the Acquisition, Technology, & Logistics Agency (ATLA) to counter hypersonic missiles.

First developed in the 1920s, railguns are simple to understand, have a remarkable potential, and sound seriously sci-fi. The principle behind them is fairly simple. In fact, any first-year engineering student could build a decent one without much effort.

Essentially, it's the equivalent of taking an electric motor and flattening it out so that instead of making the armature spin around, the magnets shoot it across the room, which can be a bit aggravating. It's the principle behind maglev trains and the fighter plane launchers on the latest US aircraft carriers. For the railgun, it's used to propel projectiles at tremendous speeds without the need for cordite or other explosives.

The United States, India, China, France, and Germany have all looked at developing a practical railgun for warships and land artillery, but Japan has shown the keenest interest since 2016, pouring in 46.3 billion yen (US$300 million) in the past three years.
