Counter-Drone Tactics Using Autonomous Systems

"Unfortunately, most current counter-drone systems look like someone strapped $500,000 worth of sensors to a laser pointer and hoped for the best. Enter yet another tech marvel from Sweden: the Kreuger 100. A stripped-down, software-driven interceptor that’s less F-35 and more Ikea flat-pack missile. That’s not an insult. That’s the future. Launched by Nordic Air Defense (NAD), a Stockholm startup that clearly got tired of watching Europe buy defense tech from across the Atlantic, the Kreuger 100 was designed from the ground up to be cheap, scalable, and fast to deploy. What sets the Kreuger 100 apart isn’t just what’s inside but what’s missing. In the traditional world of air defense, interceptors come bloated with cost-heavy payloads: radar transceivers, laser rangefinders, gimbaled optics, complex gyroscopic stabilization, and propulsion systems that look like they were ripped from Cold War cruise missiles. The Kreuger 100 throws that model out the window and replaces it with a radical, minimalist architecture where the real brainpower lives not in hardware but in code. At the heart of this interceptor is a machine-learning-based flight control algorithm that adapts to environmental variables in real time: wind, angle of attack, target evasion maneuvers, and even thermal distortion caused by cluttered urban landscapes. Instead of reacting like a heat-seeking missile on rails, the Kreuger 100 behaves more like a predator drone with a nervous system. It doesn’t just follow, it predicts. It calculates an interception course based on probabilistic modeling of the drone’s behavior, a kind of anticipatory flight path generation that gives it a split-second edge in a knife fight in the sky. And unlike traditional systems locked into proprietary software ecosystems, the Kreuger 100 is designed to run on modular, updateable codebases. That means when a new drone threat emerges, say, a smaller, faster loitering munition or a decoy swarm, the Kreuger’s software can be updated without touching the hardware. In war, that adaptability is gold. Its infrared tracking system, while simple by Western standards, is fully integrated into this software layer. Rather than relying on heavy stabilization and high-end optics to isolate a heat signature, the Kreuger uses digital signal processing and software-based noise filtering to lock onto targets even with low contrast or amidst thermal clutter. It’s not the most powerful eye in the sky, but it’s smart enough to see through fog, rain, or smoke and still make the shot. [...] In short, the Kreuger 100 doesn’t match legacy interceptors feature-for-feature. It leapfrogs them by reducing complexity, cutting costs, and moving the brain from silicon to code. The result is a nimble, adaptable air defense solution that behaves more like a swarm AI than a missile." From https://archive.ph/pumek

A new “interceptor” drone prototype is being tested in Russia. It is designed to disable other UAVs by entangling their propellers with Kevlar threads. Insight: This is part of the growing counter-drone (C-UAS) trend, where instead of using expensive missiles or jammers, lightweight and relatively cheap drones are developed to neutralize enemy UAVs. Kevlar threads are strong, heat-resistant, and nearly impossible to snap under propeller stress, making them effective for tangling and stalling motors. Such “drone catchers” are especially useful against small quadcopters used for reconnaissance or kamikaze missions, which are hard to target with conventional air defense. Russia, Ukraine, and several NATO states are experimenting with similar concepts — from drone nets, entanglement mechanisms, to autonomous kamikaze interceptors. The advantage is low cost per kill, but the drawback is limited use against larger, faster UAVs or fixed-wing drones at higher altitude.

Drone Warfare 3.0: Autonomous Attack Systems Without Human Operators In recent months, combat operations in Ukraine have confirmed the use of V2U-class drones — fully autonomous loitering munitions. These platforms operate without radio links, without operator control, and make independent decisions using onboard AI. The V2U drone is equipped with a Jetson Orin module, GPS, and a real-time video analysis system. It is capable of detecting, identifying, and engaging targets autonomously based on image recognition — without any communication with the ground. Reports suggest that this system can detect and strike mobile air defense teams by visually analyzing their shape, spatial configuration, and signature — not by signal detection. Key capabilities of this threat class: No radio link = not susceptible to jamming No operator = no remote interception Autonomous target recognition and strike Immune to classic EW and GPS spoofing Scalable production using commercially available components Operational implications: Legacy counter-UAS strategies based solely on signal denial (jamming) are no longer sufficient. Modern countermeasures must include: ✅ Optical, thermal and radar-based early detection ✅ Programmed airburst munitions (30–35 mm) for kinetic response ✅ High-speed interceptors and directed energy weapons ✅ Mobile and visually-masked defense systems ✅ SOP revisions for autonomous threat timelines Strategic takeaway: Drone Warfare 3.0 is not future warfare — it’s current reality. Nations that fail to adapt their layered defense architecture to address autonomous systems will face growing vulnerabilities across the battlespace.

V Corps Just Battle-Tested 30 Counter-Drone Systems. Only 3 Passed the "Ukraine Test." Project Flytrap 4.0 revealed that most C-UAS tech fails against real drone tactics. What worked • Autonomous hunter-killers that match drone speeds • Passive sensors are invisible to enemy EW • Squad-portable jammers under 20 lbs What failed • Anything requiring perfect weather • Systems needing 5+ operators • Solutions costing more than targets FPV drones with fiber-optic control laugh at your RF jammers. 30-50km range. Zero emissions. Unstoppable with traditional tech. That's why Flytrap tested kinetic interceptors. When you can't jam, you hunt. The timeline that matters • October 2025: CMMC Level 2 required • January 2026: AI platform goes live • FY26: $13.6B in counter-drone funding Here's the play: Traditional defense primes are too slow. Startups like Allen Control and Hidden Level own the speed advantage. But they need manufacturing partners. Integration support. Cleared personnel. That's your opening. Drones turned every soldier into a target. Flytrap proved we can fight back. But only with systems that think like startups and scale like armies.

Epirus has just demonstrated something that deserves everyone’s attention. In a live fire event, their Leonidas system disabled 61 out of 61 drones, including a swarm of 49 flying simultaneously. That is not a lab test. It is proof that high power microwave pulses can defeat real threats at scale, with speed and cost firmly on our side. This matters because it proves the one-to-many effect is no longer theoretical. For years, counter-drone defense has meant expensive missiles, short magazines, and long resupply chains. Leonidas shows that pulses can flip the cost curve and reset the engagement balance. But pulses alone are not the complete solution. The Bio-Inspired Distributed DEW and AIRES framework was developed to fill out the entire kill spectrum. A resilient doctrine requires layered options: • Soft Kill: jam uplinks, confuse seekers, and create false corridors with deceptive signatures   • Medium Kill: adaptive countermeasures against hardened or EMI resistant platforms   • Hard Kill: pulsed energy, microwaves, or lasers that burn out circuits and disable optics  One node with three modes of action. When those nodes are distributed, capacitor fed, and connected through a resilient mesh, they deliver more than point defense. They create a kill web that enforces one rule: nothing flies without a green light. Leonidas proves the physics of the hard kill. The distributed DEW doctrine shows how to extend it into a grid that lowers peak power demand, reduces friendly fire risk, and keeps firing under GPS denial or communications blackout. Together, these pieces form a system that is scalable, resilient, and affordable in ways that traditional batteries or single point defenses cannot match. The opportunity now is to align these elements into a package that deploys right the first time. Not chasing salvos. Not reacting after the fact. Defining the standard of engagement for swarms.

AI-Driven Defense Systems Revolutionizing Counter-Drone Technology. These AI-driven defense systems are redefining counter-UAS (C-UAS) strategies by enabling real-time threat detection, tracking, and response. Autonomous interceptor drones, such as KAiDEN by Nearthlab, utilize advanced autopilot algorithms for precise threat neutralization. Companies like Anduril Industries are integrating sensors, machine learning, and drones to create adaptive C-UAS platforms. Legislative support for AI deployment underscores its strategic importance in enhancing airspace security against evolving threats. These innovations exemplify AI's pivotal role in modern defense systems.

Examples of Systems for Kinetic Defeat of Tactical Kamikaze Drones In an earlier post (see https://lnkd.in/dM2DKmYC ) I discussed why kinetic is definitely the way to fight short-range, unjammable (optical-fiber-based or autonomous) kamikaze drones. And I presented three categories of such kinetic counter-drone systems. In this post, I bring several specific examples of such systems that already exist, at reasonable levels of maturity, e.g. TRL7 or better. Let me restate the desired characteristics of such counter-drone systems: a. Suitable for short-range operation (under 100 m, because kamikaze drones must come close to you, and often ambush you from behind nearby trees and buildings). b. Small and light (under 100-200 kg?) to be installed on any tactical vehicle (without interfering with the vehicle's primary function. Or even on a small ground robot accompanying an infantry team, in mobile warfare. c. Able to defeat several (say, 3-5) attacking drones, on the move. d. Fully autonomous because humans don't react fast enough. So, here are a few examples in the categories I outlined in the previous post. 1. In the first of my categories, Iron Drone is a pod of several interceptors https://lnkd.in/d3kncs6n Each autonomous interceptor can guide itself towards the incoming kamikaze drones and defeat it. Although the video shows a stationary ground-based pod, Eric Brock tells me a vehicle based version is becoming available. 2. In the second of my categories (interceptor drones hovering over a vehicle or a team of dismounts), I and my contacts are unable to find any examples! Entrepreneurs out there, are you listening? 3. In the third of my categories, autonomous direct-fire RWS Bullfrog https://lnkd.in/d9fnhjuW can protect a vehicle, and Steven Simoni tells me they can do on-the-move fires and are developing a mini-Bullfrog to accompany dismounts. Finally, any counter-drone systems must be able to detect and track a kamikaze drones. Applicable to any of the three categories I outlined, a passive detection-tracking system from Data Capture Systems GmbH is compact and light, and Johannes Glasemann tells me they plan to put it even on a robo-dog. Several other well-known systems are similar to these examples, in some aspects. However, they are too far from the characteristics I listed above (too bulky, not autonomous, etc.), so I don't mention them. If I am mistaken -- please talk to me, I will be happy to stand corrected. Do you know other examples that do meet the desired characteristics?
