| Why it matters | IDET is Central Europe's leading defence procurement gateway, drawing military delegations from more than 50 countries and serving as the primary export showcase for the Czech defence industry. For SMEs and startups, it offers direct access to primes such as CSG, Rheinmetall, and KNDS, plus a dedicated startup and innovation focus, making it a practical venue to secure contracts and partnerships in a fast-growing regional defence market. | The anchor event for anyone selling to the US Army. Program offices and primes are present in force; ideal for SMEs seeking subcontracting and teaming opportunities. | The fastest way for engineers and early founders to plug into the European defence-tech builder scene, meet operators and get noticed by funds active in the space. | This is the primary procurement-facing event for Quebec's naval supply chain, where federal ministers have used the platform to announce National Shipbuilding Strategy (NSS) contracts and submarine procurement updates — making it a critical intelligence touchpoint for any company seeking Davie, Royal Canadian Navy, or Canadian Coast Guard business. With ~750 participants and ~65 exhibitors, it is compact enough for SMEs and startups to gain direct access to prime contractors such as Chantier Davie and Thales Canada. Pre-scheduled B2B meetings with national and international outsourcers give exhibitors a structured path to new contracts. |
