Alpine Eagle Sentinel

Counter-drone warfare, moved into the sky — Alpine Eagle is the outlier of Europe's interceptor-startup wave: where everyone else launches the interceptor from the ground, this Munich company puts the whole kill chain in the air. Its Sentinel system is a reusable "mothership" drone that flies high, carries smaller interceptor drones, spots hostile drones with its own airborne radar and AI, and sends its chasers to net or ram them — from above, where terrain hides nothing and the sensor is not a stationary target. The Bundeswehr is its launch customer; Ukraine has trialed it in combat. It is the airborne answer to a problem everyone else is solving from the ground.

Overview

Alpine Eagle is a Munich defense-tech startup (founded 2023) whose product, Sentinel, is the airborne member of Europe's 2026 affordable-interceptor wave — and its most conceptually distinct. Where the Tytan, Frankenburg Mark 1, Sting and Merops systems launch an effector from the ground, hand or vehicle, Sentinel puts sensing, command and interceptors all in the air: a sophisticated, reusable "mothership" UAV flies at altitude carrying airborne interceptor drones, uses an AI-driven radar and electro-optical sensor suite to detect low, fast drones that ground radars miss, and dispatches its chasers to capture hostile drones with nets or destroy them kinetically — all orchestrated by the hardware-agnostic Sentinel-OS software so one operator runs a defensive swarm as a "mission manager, not pilot." The pitch is the airborne layer's advantages: a bird's-eye line of sight unobstructed by terrain, mobility (no stationary launcher to target), wide-area coverage, and "offensive" reach to hunt enemy ISR drones near or behind the front. Founded by ex-Airbus/Volocopter/Quantum Systems engineer Jan-Hendrik Boelens with sensor-fusion scientist Timo Breuer, Alpine Eagle has the German Bundeswehr as its launch customer (operational trials from 2024), has trialed Sentinel with Ukrainian forces, and raised a €10.25 million seed (2025). The honest caveats, as with every startup in this section: nearly all performance specs are undisclosed or company-claimed, there is no independently verified intercept tally, and a circulating "APKWS rockets / hundreds of intercepts" figure is a conflation with the VAMPIRE system — not Sentinel, whose effectors are interceptor drones.
