We are dedicated to overcoming the asymmetric challenges inherent to the future of national security.

Los Angeles, CA
At the XVIII Airborne Corps’ counter‑UAS proving ground, Leonidas software integrated with the U.S. Army’s sensor and C2 network and went head‑to‑head with live red‑team UAS threats, including swarm scenarios at Scarlet Dragon 26-3.​ We fielded a DFT Sensor Tower and Manta AI-Assisted Sensing system and demonstrated Leonidas’ full C2 stack via an API now in the Army API Marketplace, supported swarm ops, and proved readiness in real‑world field conditions alongside Soldiers.​ Grateful to the @18airbornecorps for the opportunity to show how Leonidas fits into the Army’s integrated counter‑UAS architecture.​ Read more about the exercise from the Department of War: war.gov/News/News-Stories/Ar…

We’re excited to welcome Justin Jordan as SVP of Growth. A former Marine and drone-industry operator, Justin has scaled government and international defense businesses by winning programs and expanding federal and allied partnerships. He’ll own our growth strategy across the U.S. Government, commercial, and international partners so our systems protect warfighters, civilians, and critical assets, and stop autonomous threats before they reach the fight. Welcome aboard, Justin.

SPEAKER ANNOUNCEMENT: Andy Lowery, CEO of @epirus will be joining the Space & Defense Investor Summit. Epirus is scaling Leonidas, a solid-state high-power microwave system that defeats drone swarms non-kinetically with what the company calls an unlimited magazine. The company has raised over $550M from @8vc, @WashingHarbour (& others) and is moving Leonidas into Army programs and allied fielding. 📍 The Beverly Hilton 🗓️ November 3 - 4, 2026

One system to defeat many threats, wherever Marines go. HAVOC is the second generation of Epirus HPM built for @USMC following the Expeditionary Directed Energy Counter-Swarm (ExDECS) system we delivered in 2025. Based on ExDECS feedback, the HAVOC system will introduce step-change improvements: more power, greater electronic lethality, wider coverage and better operational reliability.

🚨 JUST IN: @USMC has awarded Epirus an $11M contract for the High-power Microwave Autonomous Vehicle Operational Capability (HAVOC) program. Epirus will deliver a sled-mounted HPM system for universal integration with manned & unmanned ground vehicles. Learn more: epirusinc.com/press-releases…

With support from Epirus, engineers & Soldiers are building side-by-side in Lawton, Ft. Sill. As we continue to build in Oklahoma, the @FISTAinnovation has selected an Epirus-developed high-power RF amplifier for use in its two new anechoic chambers. This commercial test instrument, the EPW-2001, will enable FISTA to independently conduct specialized RF testing & evaluate HPM effects on electronic targets.

@TomColeOK04, Chairman of the House Committee on Appropriations, joined Epirus & FISTA leadership for a ribbon cutting ceremony to mark the facilities’ opening. The chambers sit near the Joint Counter-small Unmanned Aircraft Systems University & the U.S. Army’s Fires Center of Excellence & Air Defense Artillery School.

Happy 250th, America! 🇺🇸 Two hundred fifty years ago, the idea of defeating a swarm of drones with a high-power microwave system would have sounded like witchcraft. The pace of change in defense technology has compressed what used to take decades into years, and capabilities like high-power microwave that were theoretical for most of our Nation’s history are now operational realities. That innovative leap says as much about American ingenuity as anything else we’ll celebrate this Fourth of July. The founders bet on a nation that could out-invent anyone. Two and a half centuries later, that's still the bet we're making.

On both sides of the Atlantic, the drone threat has become more sophisticated, more accessible & more urgent. To discuss the capabilities needed to meet this challenge across NATO states, we welcomed officials from the Hellenic Ministry of National Defence to Epirus HQ. And, yes, our Greek-inspired company name may have come up, too!

Yesterday, Epirus high-power microwave was demonstrated to @SecWar & @USWREMichael. Its one-to-many capability pairs low-cost, low-collateral effects with an unlimited magazine to defeat swarms, fast-moving and fiber-optic-guided drones. HPM is effective, proven and ready to deploy at scale as part of a layered defense architecture.

Time to scale.
Today, the first milestone test of Golden Dome for America (GDA) was a full mission success — and I was honored to witness it firsthand. Cutting edge directed energy was harnessed and the Dynamic Defense Autonomous Defeat (DDAD) system flawlessly and autonomously cued, targeted, and eliminated a multitude of incoming threats. This test was executed on schedule — and dynamically defeated every threat. I watched our elite warfighters integrate with next-generation technology to stop incoming drones and cruise missiles dead in their tracks. Traditional Primes and emerging Primes are competing, collaborating, and winning—delivering on President Trump’s priority. This historic milestone was only made possible by the One Big Beautiful Bill—giving us the funding to deliver on the ultimate shield to protect America. President Trump is making President Reagan’s Strategic Defense Initiative (SDI) vision a reality. With Golden Dome, the War Department will defend our homeland more powerfully than ever before. Golden Dome is real, powerful, and on track.

Threats are scaling. So are we. As we enter a new phase of operational growth, we're pleased to welcome Mark Cuyler as COO and Mark Horton as CPO, two leaders who have built at this level before. Read more: epirusinc.com/press-releases… Welcome aboard, Mark & Mark.

"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…
