The most effective counter-drone system is not a radar dish on a tripod. It is a drone itself, flying a persistent, 360-degree overwatch. That is the foundational bet of Alpine Eagle GmbH, a Munich-based defense startup whose Sentinel system uses swarming UAVs equipped with K-band radar to detect and neutralize enemy drones. Since 2024, its technology has moved from prototype to operational deployment with the German Bundeswehr and into live testing against FPV drones in Ukraine [Dronelife, March 2026] [United24 Media, August 2025].
A technical wedge in a crowded field
The crowded counter-UAS market is dominated by ground-based systems, which face inherent limitations with terrain and line-of-sight. Alpine Eagle's wedge is to move the sensor and effector into the air. The Sentinel system deploys a network of UAVs, each carrying an active radar operating in the 24.45-24.65 GHz band. This creates a mobile detection bubble, with each drone providing a 120-degree field of view for collective 360-degree coverage [Unmanned Systems Technology, 2025].
The company claims a detection range of up to 4 kilometers for Group 1-2 drones (small, tactical UAVs) with an accuracy of 10 meters or less at a 1-kilometer distance [Unmanned Systems Technology, 2025]. Upon identifying a threat, the system can deploy airborne interceptor drones for kinetic neutralization or use electronic countermeasures, all coordinated by an edge AI layer for target discrimination. This architecture is designed for complex environments,urban areas, moving convoys, or GNSS-denied zones,where fixed systems struggle.
The founder's aerospace pedigree
Execution in defense hardware requires deep domain credibility, which Alpine Eagle's leadership appears to have secured. CEO Jan-Hendrik Boelens was previously chief engineer at Airbus, CTO at urban air mobility company Volocopter, and CTO at drone manufacturer Quantum Systems [HTGF, Unknown]. His co-founder, Director Timo Breuer, brings a research background from Microsoft Research and the Fraunhofer Society [HTGF, Unknown].
This technical pedigree was likely a key factor in attracting a seed round of €10.25 million (approximately $10.9 million) led by IQ Capital, with participation from General Catalyst, HCVC, HTGF, and Expeditions Fund [HTGF, Unknown] [Tech.eu, March 2025]. The investor group blends deep-tech and defense-focused venture capital, signaling confidence in the team's ability to navigate the long development and sales cycles inherent to the sector.

Traction beyond the slide deck
For a hardware startup founded in 2023, Alpine Eagle has moved with notable speed from development to documented field use. Its progression follows a clear, de-risking path common in defense tech.
- Initial deployment. The system was first deployed with the German Bundeswehr in 2024, providing an early, credible reference customer within its home market [Dronelife, March 2026].
- Operational testing. By August 2025, Sentinel units were undergoing operational testing in Ukraine, tasked with defending against first-person-view (FPV) and strike drones [United24 Media, August 2025].
- Commercial expansion. The company has since secured contracts with three additional European customers and expanded its commercial operations into the United Kingdom and the Netherlands [Unmanned Systems Technology, March 2026].
- Production scaling. In March 2026, Alpine Eagle announced it was scaling production of Sentinel systems at a new facility in Munich and had entered a partnership with Dutch UAV maker DeltaQuad to integrate Sentinel with the Evo platform [Dronelife, March 2026].
The company also reports it has achieved seven-figure revenues since launch, a critical milestone for a capital-intensive hardware business seeking further growth funding [Defense Advancement, 2026].
The scalability question
Alpine Eagle's technical approach is elegant, but scaling a hardware-and-software system for national defense introduces a different class of challenges. The most immediate question is manufacturing and supply chain resilience. Building swarming UAVs with integrated radar is not a software deployment; it requires sourcing specialized components, securing production lines, and ensuring consistent quality under potential export controls. The new Munich production facility is a direct response to this [Tech.eu, March 2026].
The second pressure point is algorithmic robustness. The system's effectiveness hinges on its edge AI correctly discriminating between threats and civilian drones in cluttered electromagnetic environments. False positives or missed detections in live combat scenarios carry extreme consequences. While testing in Ukraine provides invaluable real-world data, the leap from testing several systems to fielding hundreds across a continent is a test of software reliability at scale.
Finally, the competitive landscape, while not detailed in public sources, is formidable. Alpine Eagle is not just competing with other startups but with entrenched defense primes and electronic warfare specialists. Its wedge is technological, but its moat will be built on procurement contracts, certification, and the ability to integrate into broader military command-and-control systems,a sales and engineering marathon.
The next twelve months
The coming year will be defined by production execution and partnership depth. Scaling the Munich facility to meet demand from existing and new European contracts is the primary operational hurdle. The partnership with DeltaQuad is a smart move to use an established airframe, but the integration and joint go-to-market success need to be proven.
Financially, with over €10 million in seed capital and seven-figure revenues, the company is likely positioning for a Series A round to fund larger production runs and further international expansion. Landing a contract with a NATO member state beyond Germany would be a significant traction signal for investors.
Technical Breakdown: The Sentinel Stack Sentinel is a full-stack system. The hardware layer consists of COTS (commercial off-the-shelf) UAVs modified with proprietary radar pods and interceptor attachments. The software layer, Sentinel-OS, handles swarm coordination, sensor fusion, and threat classification at the edge. The radar's K-band selection is a tradeoff: it offers good resolution for small targets but can be attenuated by weather. The system compensates with multiple nodes and acoustic sensors for redundancy [Unmanned Systems Technology, 2025].
The sober assessment for scale is that the architecture's distributed nature is both its strength and its vulnerability. Network latency, drone endurance, and counter-swarm tactics from adversaries are unsolved problems at the deployment levels Alpine Eagle is now targeting. Their next phase depends less on the elegance of the idea and more on the grim, practical logistics of building, shipping, and supporting hundreds of complex robotic systems in active conflict zones.
