#299 Andy Lowery - Inside the World’s Most Advanced Drone Killing Machine

Leonidas represents a new class of scalable, high-powered microwave systems designed to defend against drone threats by generating an electromagnetic shield. Its development focused on scalability, with configurations ranging from portable toolbox-sized variants to massive fixed installations capable of multi-kilometer coverage.

High-Powered Microwave System Functions as Electromagnetic Shield

Leonidas operates as a protective electromagnetic field—described by its inventor, Andy Lowery, as the first human-made force field—that disables drones and similar electronic threats. The core concept is to emit powerful electromagnetic interference (EMI) that couples voltages into a drone’s circuit boards, causing their computers to crash or servos to freeze, much like a “blue screen of death” on a PC. When a drone enters the electromagnetic bubble, its electronics succumb to the intense field, rendering it inoperable.

Protective Field Disrupts Drone Electronics Via Frequency Targeting and Beam Steering

Leonidas leverages both wideband and narrowband high-powered microwave capabilities. Unlike older narrowband systems, which were inconsistent across targets, Leonidas employs advanced hardware and AI-driven control loops to rapidly shift frequencies and algorithms to match each drone’s unique susceptibilities. This targeted approach maximizes electronic disruption, regardless of drone make.

Phased Antenna Elements Create a Single Beam, Electronically Steered Across the Sky At Microsecond Speeds

The Leonidas antenna features hundreds of miniature elements phased together to create a unified, highly energetic microwave beam. Each antenna element emits a fraction of total energy, and when all are precisely synchronized, their combined output yields a narrow, potent beam. This beam is steered electronically in microseconds, like the sweeping of a spotlight or a laser light show, allowing rapid retargeting across the sky so multiple drones can be engaged in rapid succession, seemingly simultaneously.

Spotlight-Like Beam: 5-10° Coverage, Repositionable in 60° Area Within 1 Second

The resultant microwave beam resembles a spotlight, covering an area of approximately 5–10 degrees. Electronically, the beam can be directed within a 60-by-60-degree segment of the sky almost instantaneously; combined with mechanical steering, the whole antenna can rotate at 30 degrees per second for comprehensive coverage.

[restricted term] Nitride Tech Converts DC Power to High-Powered Microwave Energy, Sustaining Pulse Durations Unattainable by Traditional Systems

At the system’s heart are [restricted term] nitride-based converters (“L-Rams”) that transform stored DC power into microwave energy with high efficiency. This technology allows Leonidas to deliver long-duration, high-energy pulses needed for comprehensive electronic disruption—a feat traditional vacuum tube-based directed energy systems cannot achieve. The continuous pulses account for multiple clock cycles of a target computer, ensuring deep and reliable interference.

Technical Specifications and Detection-To-engagement Capabilities

Leonidas’ detection and engagement workflow integrates a multi-tiered sensor network to guarantee swift recognition and takedown of threats.

System: 360-degree Detection Network; Includes Radar, Telescopes, and Sensors; Detects Threats Up to 20 Kilometers Away

Leonidas mounts a 360-degree radar, supported by electro-optical and infrared sensors, enabling detection of aerial threats—including small drones—at ranges from 10 to 20 kilometers. The collected data presents the operator with a “god view” of the operational landscape, overlaid with real-time drone positions sourced from integrated radar sensors and network-linked installations.

Engagement Range Varies With System Size: 50 Meters For Toolbox-Sized Variants to 1.5+ Kilometers For Building-Sized Installations

The modularity of Leonidas allows installations as small as a toolbox—portable but limited to engagement ranges of about 50 meters for use cases like armored vehicles or tanks—or as large as a building for defending embassies, airfields, or bases at standoff distances of 1.5 kilometers or more. Even larger arrays (up to 100×100 feet) could theoretically protect regions spanning several miles, suitable for major infrastructure defense.

System Engages Stationary Targets Via Fiber-Optics, Autonomous Drones Sans GPS/Radio, and 49-drone Swarms

Leonidas is effective against a broad spectrum of targets, including stationary objects via fiber optic detection, autonomous drones operating without GPS or radio signals, and even swarms—demonstrated by rapid sequential disabling of 49 drones in under a second. The system can focus its energy on individual drones or rapidly sweep across clusters in just fractions of a second.

Detection Systems Operate Independently or Integrate With Command Networks for Real-Time Battlefield Assignments

Detection units function autonomously or leverage network integration (such as with Anduril’s Lattice command network), facilitating early detection and optimal assignment of effectors (the Leonidas beams) to targets, similar to advanced air defense networks like Iron Dome. All installations can be networked over Starlink and UHF communication, further enhancing shared situational awareness and collective area defense.

Safety Features and Human Interaction Protocols

Leonidas is designed with comprehensive safety and operational flexibility for both battlefield and homeland defense applications.

Leonidas System Operates At Safe Frequencies and Power Levels For Biological Matter and Personnel

The system’s electromagnetic output operates at low-frequency microwave energies that pass harmlessly through biological tissue, similar to FM radio or broadcast TV signals. Andy Lowery attests to its safety for humans, animals, and plants—even standing before the active beam for up to 15 seconds is harmless, as the wavelengths used are non-ionizing and lack the energy required to damage living tissue.

Electromagnetic Beam Activates, Radiating For 10-20 Seconds per Cycle, Minimizing Exposure

Leonidas only emits microwave energy when a target is confirmed, and each engagement lasts just 10–20 seconds per cycle, minimizing overall environmental exposure.

No Risk to Aircraft or Infrastructure; Unlike Kinetic Missiles, Causes No Collateral Damage, Suitable for Homeland Defense

Because Leonidas relies on directed electromagnetic energy rather than physical projectiles, it causes no kinetic damage to surrounding structures, ...

Drone warfare is rapidly redefining the modern battlefield and homeland security, exposing vulnerabilities in traditional defense postures and accelerating the demand for adaptive, layered defense systems.

Asymmetrical Nature of Contemporary Aerial Threats

Drone Warfare: Affordable Unmanned Systems Threaten Costly Defense Assets

Shawn Ryan and Andy Lowery highlight a crucial asymmetry in today’s aerial threat landscape: affordable drones, often costing $10,000 or less, can threaten defense assets that require multi-million dollar missiles to counter. This mismatch is unsustainable and disproportionately favors attackers who can deploy large numbers of low-cost, off-the-shelf drones. The analogy is simple—using massive, expensive defenses to counter tiny, inexpensive threats is like having a lion’s cage with bars so wide that mice can run straight through it.

China's 30M Annual Drone Output Surpasses Western Missile Production, Straining Defense Replenishment

China’s drone manufacturing capability is staggering, with estimates of up to 30 million drones produced annually. This output dwarfs any Western military production capability, especially in missile manufacturing. As Lowery notes, "there’s nothing we can make 30 million of" in the U.S. military arsenal. Western defenses thus face a severe magazine depth disadvantage, compounding the challenge of countering drone swarms with traditional means.

FPV Drones With Fiber-Optic Tethers Enable Precision Strikes for Small Teams Without Advanced Military Infrastructure

The evolution of first-person-view (FPV) drones, some equipped with fiber-optic tethers, empowers small teams to conduct precision strikes without the need for advanced or resource-heavy infrastructure. These tethered drones resist radio frequency jamming, adding an element of resilience previously reserved for more advanced military systems.

Adversarial Networks: Russian Intel to Iran and Potential Chinese Drones Threaten US and Allies

The threat environment is global and increasingly networked. Russian intelligence sharing with Iran and the potential for Chinese-manufactured drones being used by adversaries heighten risks for the U.S. and its allies. Lowery and Ryan both suggest the possibility of drone threats at virtually any high-value location: military bases, intelligence agency headquarters, government buildings, and public venues.

Documented and Emerging Threat Incidents

Drone Swarms Overfly Barksdale AFB, Exposing Nuclear Storage Vulnerabilities

Recent incidents underscore these risks. At Barksdale Air Force Base, a site central to U.S. nuclear deterrence, swarms of drones in coordinated waves (twelve per wave, multiple waves) overflew critical infrastructure. The drones, impervious to jamming, completed their surveillance and departed undetected, exposing significant vulnerabilities. The origin of these drones remains unknown, underscoring the difficulty in attributing drone attacks.

Operation Spiderweb: Drone Swarms Overwhelm Air Defenses in Ukraine, Model Spreads To Middle East

Operation Spiderweb in Ukraine demonstrates how drone swarms can overwhelm even well-prepared air defenses. This same swarm tactic is now influencing attacks in the Middle East. The pattern points to drones as a vector for cheap, scalable, and devastating attacks that have a psychological and operational impact far beyond their immediate effects.

Tethered Drones With Fiber-Optic Links Resist Jamming, Requiring Physical Neutralization

Some drones employ fiber-optic tethers that make them immune to traditional radio frequency jamming. These platforms only become vulnerable to direct, physical neutralization, raising the bar for effective countermeasures.

Autonomous Drones Will Bypass GPS and Radio Signals, Becoming Immune to Jamming and Requiring Electromagnetic Pulse Defenses

The next generation of autonomous drones will not rely on GPS or radio signals, making them immune to current jamming technologies. In the future, electromagnetic pulse (EMP) defenses may be required as one of the few remaining effective means to neutralize these threats.

Layered Defense Requirements and Leakage Patterns

Defensive Layer Neutralizes 90% of Threats; 10% of Drones Penetrate, Leakage Scales With Swarm Size

Modern drone defenses are fundamentally layered, but every system admits "leakers"—threats that penetrate outer defenses. Lowery notes that nine out of ten drones are neutralized, but with swarms, ten percent still get through. When facing a swarm of a hundred, ten make it past. Against a thousand, a hundred leak through, which is alre ...

Economic Efficiency and Cost-Per-engagement Analysis

Electromagnetic defense systems like Leonidas deliver an extraordinary cost advantage in high-frequency scenarios. Andy Lowery explains that neutralizing a single drone with Leonidas costs merely five to 20 cents in energy. As usage increases—removing, for example, 50 drones per month—the per-drone cost settles into the hundreds of dollars, factoring in all operational expenses. This is a dramatic reduction compared to traditional missile interceptors, which can cost millions per shot.

The system’s economic superiority manifests when compared across use cases: it becomes especially cost-effective after neutralizing 50-100 drones, far outpacing missile-based systems. Unlike kinetic weapons, which require expensive and time-consuming resupply—often taking months for replenishment—electromagnetic systems depend solely on electrical power, enabling rapid, virtually limitless resupply during ongoing conflict. High operational tempo and system utilization continue to drive the per-shot cost lower, making Leonidas optimal for both high-value and high-volume defense scenarios.

Collateral Damage Mitigation and Homeland Deployment Suitability

A key benefit of electromagnetic systems is their minimization of collateral damage. EMP-based solutions disable drone electronics without causing shrapnel, fragmentation, or blast effects, thus avoiding risks to civilians and infrastructure. Kinetic systems, by contrast, often pose unacceptable hazards to non-combatants in populated environments, which severely restricts their homeland use. The Leonidas system’s non-destructive effects preserve much of the drone’s electronics; this allows forensic teams to recover onboard computers and trace origins, operations, and command chains—adding intelligence value to each interception.

Moreover, Leonidas avoids the shutdown risks associated with other directed energy weapons. Unlike laser-based systems—which can generate aviation hazards requiring temporary airspace or airport closures—the electromagnetic pulses operate safely around civilian infrastructure. The FAA has expressed interest in these systems due to their safety and reliability for urban or homeland defense.

Superiority in Magazine Depth and Sustained Operations

Western missile production is limited to thousands per year, while adversaries can produce tens of millions of drones annually, creating a significant disadvantage for traditional defenses. Leonidas changes this calculus—operating continuously with no need for ammunition resupply except for standard electrical power.

Electromagnetic systems like Leonidas execute attacks in rapid succession without interruption for maintenance, resupply, or reloads. Additionally, these systems can be networked; steering multiple beams at the same target can extend operational range by 50-60%, and overlapping coverage ensures robust, seamless protection without the logistical limitations faced by finite missile inventories. This adaptability and magazine depth provide a decisive edge in prolonged, high-tempo engagements.

Effectiveness Against Diverse ...

The deployment of advanced systems like Leonidas faces multiple hurdles ranging from bureaucratic inertia to regulatory constraints and production scaling challenges. The changing nature of modern conflict demands a shift from peacetime process adherence to a wartime mentality focused on rapid fielding and operational outcomes.

The "Frozen Middle" Bureaucratic Barrier to Rapid Fielding

Senior military and executive leaders increasingly mandate the urgent deployment of systems like Leonidas, recognizing the severity of drone threats, but encounter resistance from mid-level commanders and acquisition personnel. Andy Lowery describes this resistance as the “frozen middle,” where those tasked with implementation hesitate to depart from traditional, risk-averse acquisition and testing processes unless explicitly directed otherwise.

Career officers, accustomed to peacetime procurement, remain wedded to bureaucratic routines that demand exhaustive testing and the elimination of nearly all theoretical risk—targeting “99.999%” risk reduction—before new technology is fielded. This approach lags behind the urgency required by current conflict realities, as Lowery notes, “that’s a peacetime attitude... I’m not at war. We can take our time to run through the different exercises.”

However, Lowery cites examples such as the post-9/11 operational pivot and the rapid up-armoring response during the 2008 IED crisis to highlight the U.S. military’s capacity for transformation under crisis conditions. In such situations, clarity of purpose breaks bureaucratic inertia, enabling accelerated fielding and deployment that would be achievable now if the same mindset prevails. He observes that when true danger is recognized, personnel “snap into a new, like superhuman” operational mode, as seen on the USS Stennis after the 9/11 attacks and during the Army’s MRAP production surge.

ITAR Regulations and International Technology Transfer Restrictions

Leonidas, as a Category 18 directed energy weapon, is subject to U.S. International Traffic in Arms Regulations (ITAR), which impose significant constraints on export and allied provision. These controls distinguish Leonidas from less restricted dual-use drone systems, requiring additional layers of legal authorization and documented approval for international transfer.

Legal pathways for deploying these systems to advantageous theaters, such as Ukraine, remain incomplete, leaving a notable gap between the technical readiness of the system and its authorization for use by allies. Nonetheless, the ongoing Middle East conflict has accelerated efforts to remove deployment barriers. The administration is now working aggressively to enable allied access and operational deployment of such systems in response to urgent battlefield requirements. Lowery notes ongoing discussions with Israel and other partners, reflecting heightened international interest amidst active hostilities.

Path to Production Scaling and Manufacturing Expansion

California-based manufacturing currently supports a goal of building one Leonidas unit per week, with a target of producing 50 annually—a rate Lowery considers proven and feasible. Further production expansion is planned, with Oklahoma identified as the next major facility, geared toward multi-system-per-week output once sufficient demand materializes. Achieving rates above 100 units per year will require addressing asse ...
