| Why it matters | Your entry point into the EU defence innovation funnel (EUDIS, EDF). Strong fit for startups and SMEs that want EU-level visibility and follow-on funding pathways. | As NATO's flagship public-communications event in Central Europe, it puts allied air, land and rescue capabilities in front of national leadership, ambassadors, military attachés and hundreds of thousands of visitors, giving suppliers high-visibility exposure alongside primes and government forces. The Special Partner Nation mechanism (Germany in 2026) has historically opened industrial and political cooperation opportunities, and the show serves as a debut platform for new platforms and modernization programs relevant to Czech and allied procurement. |
