European Defense
Tech Hackathon
Held 6 to 8 November 2026 in Copenhagen, part of Danish Defense Tech Week.
A weekend to build for Europe’s defence.
The European Defense Tech Hub (EDTH) runs hackathons across Europe. Teams of engineers, developers and designers build for a weekend on challenges from frontline partners in Ukraine, NATO and across the EU, and show what they made on Sunday. In Copenhagen the focus areas were passive detection, unmanned surface vehicles and undersea infrastructure protection.
EDTH organises the hackathon. STAND helps students take part.
Part of Danish Defense Tech Week, 5 to 12 November.
The week opens with a Sovereign Compute Summit and the hackathon, 5 to 8 November, then moves to meetups in Aalborg, Aarhus, Odense and Copenhagen, 9 to 12 November, on electronic warfare, AI and autonomy, and drones. A Ukrainian delegation from IRON Cluster, a Ukrainian defence-tech cluster, joins the week.
The week is led by Defense Innovation Highway and the European Defense Tech Hub. They publish the full programme and the signup links.
