​Signal Intelligence. Combat First Aid. Maritime Dominance.

​Join us and 200+ hackers from across Europe and beyond for the European Defense Tech Hackathon on November 6-8, 2026, in Copenhagen, Denmark.

​Connect with fellow defense innovators, meet potential co-founders, and work on projects that have the potential to save lives!

​We'll prepare challenges based on real-world problems, and you can bring your own project. You'll get feedback from experienced mentors, and we'll put you in a position to deploy your project in the real world after the hackathon 🚀

​Challenge Tracks

​We’ll feature 10–15 challenges across domains, but this hackathon will focus especially on three mission-critical areas:

​Acoustic Detection
Develop passive, real-time acoustic systems that detect and localize battlefield threats—drones, gunfire, vehicles—faster than radar or vision.

​Combat Medics Support Systems
Build digital tools and biosensors that give frontline medics life-saving speed, accuracy, and automation under fire.

​Unmanned Surface Vehicles
Design autonomous surface platforms for maritime ISR, strike, and denial—delivering naval power without the navy.

​​Goals

​1) Solve urgent defense and security challenges: Each hackathon features a fresh set of challenges sourced directly from frontline partners in Ukraine, NATO, and across the EU—driven by real needs, not theory.

​2) Launch new careers and companies: Whether you're breaking into the defense sector or building your own product and company, we connect you with jobs, funding, and pathways toward real-world deployment.

​3) Strengthen Europe through defense innovation: Here is where Europe's top talent meets the most pressing threats. By building and shipping, we demonstrate what a fast, capable, and resilient European defense ecosystem looks like.
