Lasers are innovating modern warfare — for better or worse | Latest Tech News
[ad_1]
Earlier this summer time, Israel made navy historical past. Not with a missile, bomb or bullet — but with a beam of mild.
In a first for modern warfare, the Israel Defense Forces efficiently intercepted Hezbollah drones utilizing a high-energy laser weapon in live fight. The breakthrough weapon, developed under the Iron Beam program, quietly zapped dozens of targets out of the sky during the Iron Sword marketing campaign, marking the first confirmed use of laser cannon technology on an lively battlefield.
According to a joint assertion in late May from the Israeli Ministry of Defence, the Israeli Air Force and protection contractor Rafael Advanced Defense Systems, “soldiers from the IAF Aerial Defence Array operated high-power laser system prototypes in the field, successfully intercepting scores of enemy threats.”

The technology may sound like science fiction, but officers say this laser cannon, which resembles an outsized highlight, is something but make-believe.
Israel’s success might signal a turning level in the race to develop laser weapons, but it’s far from the only participant on the sector. China was accused last month of focusing on a German plane with a laser during an EU operation. Germany called it “entirely unacceptable,” although China denied the declare. Meanwhile, Chinese scientists are reportedly developing a microwave-based beam weapon that
resembles the Death Star and is succesful of combining a number of sources into one high-powered shot.
Russia not too long ago unveiled the “Posokh,” a laser weapon described as a “ray gun” for downing drones. Russian Airborne Forces also showcased a prototype laser rifle in March designed to defend civilian infrastructure from UAV assaults.
Laser weapons, formally recognized as directed power weapons (DEWs), have been on the global radar for a long time. But until now, they’ve largely lived in research labs and protection commerce exhibits. More than 30 international locations are developing the technology — and the US navy alone spends $1 billion yearly on high-energy laser (HEL) research.
“The Army, Navy and Air Force have all been developing laser weapons,” says Dr. Iain Boyd, PhD, director of the Center for National Security Initiatives at the University of Colorado Boulder. “The Navy has installed HELs on several ships, the Army is using them for base defense and vehicles, and the Air Force has studied installing HELs on fighter jets.”
Are lasers poised to turn out to be the weapon of selection for modern warfare? Boyd tells The Post he expects to see “a steady increase in the use of high-energy laser weapons in the coming years. It is still relatively immature technology, but as the remaining challenges are overcome, their potential to change some aspects of warfare will be realized.”

For the second, the Iron Beam — recognized in Hebrew as Magen Or, which interprets to Shield of Light —exhibits the most promise. An offshoot of the Iron Dome, Israel’s air protection system that’s been operational since 2011, the Iron Beam was designed to “complement the Iron Dome and work alongside it, not replace it,” says navy analyst Yaakov Lappin, who’s been intently following the technology for years.
But the Iron Beam guarantees one thing no other weapon can ship: photographs that value a few {dollars} apiece. “It’s vastly cheaper,” Lappin says.
Israel presently spends upwards of $100,000 per Iron Dome interceptor. That’s a steep price to shoot down enemy projectiles that may cost just a few hundred {dollars} to construct. The Iron Beam’s electric “bullets,” by distinction, are virtually free.

“They are described as having an ‘infinite magazine,’ ” says Dr. Boyd. “Unlike guns and rocket launchers that have a finite number of munitions available, as long as a HEL has electrical power, it can keep on firing ‘bullets’ of photons.”
The US, meanwhile, has yet to deploy lasers in real-world fight despite a long time of research. The Army’s Stryker-based laser, Navy’s ship-mounted HELs and Air Force packages all stay in take a look at phases.
“I am not content with the pace,” US Navy Vice Adm. Brendan McLane said in a keynote speech at the Surface Navy Association confab in 2024. “We must deliver on the promise this technology gives us.”

America’s laser weapon desires go back to Ronald Reagan’s 1983 “Star Wars” Strategic Defense Initiative, a $200 billion attempt to shoot down nuclear missiles with space lasers. That program fizzled out by 1993. Subsequent efforts, just like the joint US-Israel “Nautilus” laser in the late ’90s, also stalled for being too cumbersome, weak and slow.
The pivot got here with solid-state lasers which are smaller, more environment friendly and electric reasonably than chemical.
Israel had one key benefit over other nations in the race to develop lasers, says Brian Wang, a science author and co-founder of the favored tech weblog Next Big Future. “The US has spent billions over the decades, but Israel had actual fighting as a forcing factor to get this stuff working and deployed,” he explains.

The breakthrough got here when Israeli engineers deserted the outdated thought of firing one giant beam and instead developed a system that fires a whole bunch of small, coin-sized beams. These beams lock onto a single susceptible spot, often recognized via telescopic reflection, and bombard it in succession until the menace is neutralized.
The Iron Beam makes use of optical fiber lasers, which are basically souped-up industrial lasers, to destroy aerial threats. “Electricity is used to excite atoms or molecules,” explains Wang. “They emit high energy photons, and all the photons are concentrated using mirrors. The laser heats a critical area — say, the fuel tank or warhead — until the missile fails.”
Lasers convert electrical power “into a focused beam of light particles, or photons,” says Boyd. “Depending on the energy, they can cut, melt, combust or destroy a target.”
In sensible phrases, the Iron Beam vaporizes drones with surgical precision. But there are limits. HELs presently can’t intercept long-range ballistic missiles like those focused by Israel’s Arrow 3, which shoots down threats outdoors the Earth’s environment. For now, lasers stay short-range guardians.

Also, a weapon succesful of melting metallic at 2 kilometers isn’t precisely energy-efficient. A 100-kilowatt laser requires a huge energy source and cooling system. The most superior (and smallest) prototypes draw 300 kilowatts — enough to energy 30 properties — and are only about 50% environment friendly, which means they produce immense waste heat.
This limits where and how the weapons might be deployed. And there’s another catch.
“The effectiveness of laser beams can be diminished through interaction with a variety of environmental phenomena,” say Boyd. Rain, fog, mud and smoke can scatter laser beams, lowering their effectiveness. “The laser needs to stay locked on a target for several seconds to be effective,” he provides.
Which is why naval lasers, like those examined on the USS Preble, haven’t seen extensive use. The sea is a famously unforgiving place for precision optics.

A misplaced beam can also trigger severe unintended injury. As Boyd warns, there’s concern about potential collateral results. “A laser beam reflecting off a surface could blind someone,” he says. “Or if it misses a target, it could travel hundreds of miles. There is a need to ensure no innocent party is affected.”
The UN banned laser weapons designed to blind in 1995. But with nations like Russia and Turkey reportedly fielding HELs, up to date worldwide guidelines could also be overdue.
And then there’s the conspiracy crowd. Social media has fueled weird theories claiming authorities lasers have began wildfires in California and Hawaii, an thought consultants flatly reject.
“I am very skeptical about these claims,” says Boyd. “Installing a laser of sufficient power to start a fire on a drone is not simple. For a laser to be effective, you need to have very fine pointing control to ensure that the beam stays precisely on the target.”
Dr. Iain Boyd, PhD,, director of the Center for National Security Initiatives at the University of Colorado, says he expects to see “a steady increase in the use of high-energy laser weapons in the coming years.”
The Iron Beam guarantees one thing no other weapon can ship: photographs that value a few {dollars} apiece. “It’s vastly cheaper,” Yaakov Lappin says.
Achieving that during flight requires refined technology, Boyd says, and there are “probably more effective ways of starting wildfires from drones than lasers.”
In a world where a $500 drone can destroy a $10 million tank, militaries are determined for cheaper, smarter defenses. Lasers offer just that, if they’ll overcome their limitations.
Israel’s success might mark the start of a new period, one where the flash of a laser, not the roar of a missile, is what retains the skies protected.
