Drone-frying defense firm Epirus raises $250 million
Epirus plans to expand production of its directed-energy weapons and jump into overseas and commercial markets on the heels of a $250 million funding round.
Why it matters: Powerful lasers and microwaves are exploding in popularity as militaries scramble to more effectively — cheaply, quickly, sustainably — counter drones.
Widespread adoption, however, is still lacking.
Follow the money: This latest funding round, led by 8VC and Washington Harbour Partners LP, pushes Epirus' venture account beyond $550 million.
The company previously won a $66 million prototyping contract with the U.S. Army Rapid Capabilities and Critical Technologies Office.
How it works: Epirus makes Leonidas, which can be towed or mounted to combat vehicles like the Stryker. It zaps electronics with blasts of energy.
This can bring down handfuls of drones and kill small motors.
More than two dozen directed-energy initiatives are underway across the military, according to a study published by the Emerging Technologies Institute.
What they're saying: "A new era of threats mandates a shift from a 'one to one' mindset to a 'one to many' way of thinking for short-range air defense," CEO Andy Lowery said, "and we are primed to support the Department of Defense in this new way of warfare."
What's next: Epirus will open what it's calling an "immersive simulation center" later this year in Oklahoma, home to Fort Sill and the Joint Counter-Small UAS University.

Israel becomes the first country to down drones in combat with a laser weapon
Israel's military used new laser weapons to kill enemy drones, making it the first country to do so in a war. It marks a major development in the fielding and use of these experimental weapons, which militaries worldwide are developing to deepen their defenses against drones and missiles, reducing the strain on other missiles and other projectiles. Israel's Ministry of Defense announced that soldiers from Israeli Air Force Aerial Defense Array deployed and operated a high-power laser system prototype, which successfully intercepted enemy threats. It is a big step closer to strategists' vision of a future battlefield where the expanding threat of missiles and drones can be countered by the zaps of laser weapons that have an unlimited magazine. A video shared by the Israeli Ministry of Defense showed the laser systems in action, in at least 3 interceptions. One engagement shows the laser igniting the drone's wingtip, causing it to spiral and crash. Brig. Gen. Yehuda Elmakayes, head of the ministry's defense and research directorate, said prototypes have previously been deployed "culminating in the world's first successful high-power laser interceptions on the battlefield." Feedback from the use of the weapons will continue to inform their use and development, he and other officials said in a statement shared with BI. The systems are made by Israeli-based defense company Rafael Advanced Defense Systems. They're directed energy weapons that point an intense beam of light at a target and use heat to damage or destroy it; these processes demand pinpoint accuracy and high power. The defense ministry said the weapons "complement the more powerful Iron Beam system," a larger network of similar systems that's in the works. Iron Beam is estimated to cost $500 million and would add another layer to Israel's layered air defenses — one especially useful against the kinds of drones that Hamas and Hezbollah wield. Laser weapons have been a priority for militaries around world, especially in the Middle East, where countries are racing to field the technology. Besides Israel, Saudia Arabia is using Chinese systems to develop laser air defense capacities, while the United Arab Emirates is working on its own system. The US, too, is actively working on laser prototypes, such as the AN/SEQ-3 Laser Weapon System made by Kratos Defense & Security Solutions, as well as microwave emitters and other directed-energy weapons. Officials have suggested lasers are particularly useful for taking out cheaper enemy targets like drones rather than expending expensive missile interceptors. That's been at the forefront of conversations around conflicts in waters around the Middle East, where the US has expended over a billion dollars in munitions to shoot down Houthi drones. With Israel's landmark use of the weapon, Rafael CEO Yoav Tourgeman said the system "will fundamentally change the defense equation by enabling fast, precise, cost-effective interceptions, unmatched by any existing system." There remain issues, though, surrounding the amount of power and accuracy needed for a laser to destroy its target. Lasers have struggled to work around water or through clouds or smoke, because moisture or other particles diffuse the laser's beam. And even a functional laser weapon requires a high-voltage energy source and an accurate sensor system that are likely to become targets of attack.

Israel says it used air-defense lasers to shoot down drones
(NewsNation) — For years, laser warfare was the stuff of sci-fi — but on Israel's northern border with Lebanon, Israel's laser defense system just got real. Israel's defense ministry confirmed it has deployed a high-powered laser to shoot down Hezbollah drones. The system, dubbed the 'Iron Beam,' has shot down drones more than 40 times in recent years, the Israel Defense Ministry said on Wednesday. A play on Israel's 'Iron Dome' air-defense system, military analysts have said the technology could be the dawn of a new era in air defense. Hounds and Heroes pairs veterans with therapy animals The Iron Beam isn't a missile — unlike the Iron Dome, which fires costly interceptors into the sky. The laser system uses a beam of directed energy to melt targets midair with no explosion or impact, just instant heat and precision. According to military officials, more than 300 hostile drones were launched against Israel, and the laser helped stop dozens of them. Defense experts have said that lasers, unlike missiles, fire at the speed of light and cost pennies on the dollar to operate, making them an attractive option in a long conflict. 'It costs around $50,000 for one of Israel's Iron Dome to mirror interceptors. These bring those costs down to somewhere around $1. So it, you know, disincentivizes these kind of conflicts,' said Zev Faintuch, head of intelligence for Global Guardian. NewsNation celebrates Fleet Week skydiving with Navy SEALs The lasers have only been used on drones, which are relatively slow-moving targets, a potential downside. Then there's the weather to consider. 'Dust could be a big factor, but so can rain as well,' Faintuch said. 'So, it's unclear if this system can kind of overcome those inherent challenges with direct energy weapons.' While Israel is the first country to publicly confirm using the laser system in live combat, several other countries, including the United States, have also tested this kind of futuristic technology.

Israel Lasers Intercept ‘Dozens' of Drones in Major Leap
Israel's military used a high-powered laser to take out drones in combat, the Israeli Defense Ministry said, a significant step toward laser technology being used to intercept real-life threats on the battlefield. Two laser air defense systems have intercepted "dozens and dozens" of threats, most of which were unmanned aerial vehicles (UAVs) launched by Iran-backed militant group Hezbollah from Lebanon, retired Brigadier General Daniel Gold, the head of defense research and development for the Israeli Defense Ministry, told Newsweek. Israel first used a laser system in the early days of the war, Gold said. Israel launched a full-scale war on Palestinian militant group Hamas in Gaza following the organization's unprecedented October 7 attacks in 2023, and battled Hamas-aligned Hezbollah over Israel's northern border until a fragile ceasefire ended full-scale hostilities in November 2024. Israel is one of several countries developing high-powered lasers to take out threats in the sky, most suited to intercepting cheap drones that would be incredibly expensive to shoot down with interceptor missiles. While costing almost nothing to fire, the setup costs for these laser systems are huge. But interceptor missiles for Israel's vaunted Iron Dome short-range air defense system cost tens of thousands of dollars each, racking up an eye-watering bill when defending against high numbers of targets. Analysts say lasers, a type of directed energy weapon, can be very useful as part of a larger web of air defenses, able to knock out smaller, slower targets but vulnerable to bad weather conditions. The U.S. military said in 2024 the Army had used lasers to intercept drones in the Middle East, but did not provide further details. The U.S. military has tested directed energy weapons in the Middle East, the commander of the U.S. Central Command (CENTCOM), General Michael Erik Kurilla, separately told lawmakers back in March 2024. The Israeli Defense Ministry said the government, military and Rafael Advanced Defense Systems—Israel's state-owned defense giant—had accelerated the development of "revolutionary" systems and achieved "outstanding" results. It is a "major milestone," Gold said. Rafael's chairman, Yuval Steinitz, said Israel was the "first country in the world to transform high-power laser technology into a fully operational system—and to execute actual combat interceptions." Rafael is also building the Iron Beam laser system, expected to come into service in the latter half of the year. "This system will fundamentally change the defense equation by enabling fast, precise, cost-effective interceptions, unmatched by any existing system," said Rafael chief executive, Yoav Tourgeman. The two deployed laser systems are lower-powered, more mobile and slightly less costly than the Iron Beam, Gold said. The Israeli government published footage it said showed the laser systems in action during the war. One clip looks to show at least one fixed-wing drone falling from the air after one of the wings is damaged by a laser. The footage is "entirely plausible," said David Hambling, a U.K.-based weapons and technology expert. "Drones are great targets for lasers because they are much smaller and more fragile than crewed aircraft and generally fly at slow speed without evading," he told Newsweek. "This make sit possible to focus a laser on one for long enough to burn through the skin and cause real damage, which is exactly what the video appears to show." But with drone technology evolving at a rapid pace, they could end up fitted with countermeasures to make it much harder for lasers to intercept these targets, Hambling suggested. The U.K. military said in April that British soldiers had used an "invisible radio-wave weapon" to knock out swarms of drones for the first time. Radio waves can be used as another type of directed energy weapon. The U.K. is also developing a laser-directed energy weapon dubbed DragonFire.
