The Space Defence Forum takes place at a moment when Europe’s security debate is being reshaped by industrial constraints, geopolitical fragmentation and the growing strategic importance of space. Defence can no longer be viewed only through procurement or military capability; it now sits alongside supply-chain resilience, technological sovereignty, climate exposure and orbital infrastructure as part of the same strategic picture. Co-organised by Ratio, the Bulgarian Space Cluster, SeeNext and De Re Militari, the forum is designed to bring these strands together in one setting and connect European-level debate with practical regional capability. Attendees should expect a forum with clear practical value: a place to understand how the space and defence agenda is evolving, where the most important risks and bottlenecks are emerging, and which capabilities and partnerships are likely to matter next. For companies, institutions, researchers and investors, the event offers a focused opportunity to engage with the organisations shaping this agenda, test assumptions against expert analysis and position Bulgaria within a wider European conversation on resilience, security and strategic advantage.
