Passive Detection. Naval Dominance. Infrastructure Protection.

​Join us and 100+ 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:

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

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

Undersea Infrastructure Protection

Sensing, tracking, and response for the cables and pipelines under the Baltic, and for the vessels that threaten them.

​​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.

​Visitors

​If you’re curious about the outcomes and what the teams have built, you can join the Demo Day on Sunday as an EDTH Community visitor by selecting a Community Visitor ticket.
