About the hackathon
"Flaming Shield" brings together technology developers, business, academia, and the defense community to create solutions that strengthen the security of Lithuania and the Baltic region.
The 2026 strategic mission is "Protect the Sky." Drone attacks, electronic warfare, and cyber threats are transforming the modern security landscape, so this year's hackathon calls for solutions that strengthen airspace monitoring, protection, and defense.
Organized since 2023 by the Lithuanian Riflemen's Union and Tech-Park Kaunas, "Flaming Shield" has become one of the most important platforms for defense technology (DefTech), space technology, and cybersecurity innovation in Lithuania. Here, ideas turn into prototypes, teams into long-term partnerships, and the most promising solutions reach the market and the defense sector.
Each year the hackathon brings together more than 300 participants, over 50 teams, and more than 100 mentors, experts, and investors. Its alumni — Luna Robotics, Astrolight, Broswarm, PDKinematics, TD Autonomy, and other teams — have already attracted more than 7 million euros in investment.
If you're developing technology, growing an idea, or looking for a team to solve real defense challenges — "Flaming Shield" is the place where your solution can become real change.
