"Epirus 100% could fry these and turn them off." @JTLonsdale
In this clip, Joe Lonsdale weighs in on the mysterious drone swarms that buzzed Barksdale Air Force Base for a full week and whether the incident at our nuclear B-52 base was a foreign adversary probing our nuclear infrastructure or a psyop. Joe, the founder of defense tech company Epirus, then takes on the China and Taiwan question: if Beijing seizes TSMC, can America still build drones and AI weapons systems? He explains why losing Taiwan could set AI back 5 to 10 years and exposes America's hidden dependence on China across rare earths, chips, and the global drone supply chain. @JTLonsdale

The defense industrial base was built for a different era. Sixth Domain threats don't wait for five-year acquisition cycles. Neo-Prime OEM partnerships are the fix. Epirus @GD_LandSystems are proof. Read more: realcleardefense.com/article…

Could the Golden Dome Stop Drone Swarms? “Everything’s a target now. You can’t say anymore that you’re safe just because you’re offshore or away from the battlefield. It’s not improbable for even something like a carrier to become susceptible to a drone attack. Warfare is changing—it’s a completely new way of fighting.” @epirus

Andy Lowery joins me for an outdoor demo of cutting-edge defense technology, showcasing the Leonidas autonomous ground vehicle and its role in modern battlefield protection. Built through a collaboration between Epirus, General Dynamics Land Systems, and Kodiak Defense, this mobile system integrates advanced radar, autonomous navigation, and directed energy capabilities to detect, track, and neutralize drone threats in real time. I need one of these for the studio. 😂 @epirus

I’ve been waiting a long time to sit down with Andy Lowery, the CEO of Epirus, a defense tech company leading the charge in counter-drone warfare. We get into the development of their flagship Leonidas system, designed to neutralize drone swarms, and how this technology is changing modern combat. Andy shares his background as a U.S. Navy nuclear engineer serving aboard an aircraft carrier before transitioning into leadership roles at Raytheon and into the startup world. He also talks about bringing a Leonidas system out to Vigilance Ranch where he gave a complete breakdown of how it works. You can watch both his full episode and the Leonidas demo video now on the Shawn Ryan Show YouTube channel. @epirus

“We had 12 drones come and surveil a nuclear site multiple times, and there's a struggle. They got overflown by swarms—high-tech, with a much longer range, and totally impervious to jamming. A wave of 12 completely resistant. It flew over, surveilled everything, and flew back..." What do you think it was? @epirus

Speed offers no sanctuary for drones operating against Leonidas' electromagnetic interference. Leonidas defeats fast-moving drone targets with high-power microwave energy enabled by its active electronically scanned array, high-speed gimbaling and real-time targeting software. Rapid maneuvers and complex flight patterns are no match for software-defined HPM.

The threat of drone swarms presents one of the biggest challenges to the modern battlefield. And the million dollar question (likely billion) is… how do you stop them? Well if you ask @epirus, they think they’ve found the solution. On the latest episode of Access Granted, we’re diving into the technology being developed to counter the threat of swarms and most importantly, we’re putting it to the test. 🎬 Full video out now.

As the U.S. prepares to host the 2026 World Cup, we face an unprecedented security challenge. The threat of drones is putting our soft targets at risk. We must get the right infrastructure and counter-drone systems in place now to protect the public. go.shr.lc/4sEsikQ - @washtimesoped

Congrats to the @Epirus team on their new autonomously driven Leonidas HPM. Exactly the kind of counter-UAS capability America needs right now 🇺🇸. When swarms show up over our bases and critical infrastructure, operators should be able to flip a switch, safely fry the sky, and keep our people and assets out of harm’s way.
