The Regional Defence and Security Summit brings together the key stakeholders that are building European security capacity in the Eastern Flank to advance concrete outcomes: joint procurement initiatives, investment partnerships, innovation pathways, and a shared policy agenda that reflects the region’s strategic roles.
📅 Date: October 21, 2026
📍 Location: Sofia, Bulgaria
🏢 Venue: Sofia Event Center
Europe is rearming at a pace not seen since the early Cold War. EU defence spending has risen 62.8% from 2020, exceeding the 2% NATO guideline. Defence investment alone is projected to reach €130 billion this year. The SAFE instrument is disbursing €150 billion, NATO DIANA doubling its 2026 cohort and European defence startups securing a record $8.7 billion in 2025.
On the other hand, Russia's war in Ukraine continues to define the eastern flank, while the US-Israel strikes on Iran in February 2026 brought US military assets to Sofia, put Cyprus under direct threat, and confirmed that the security environment facing this corridor is no longer single-front.
The role of NATO's Eastern Flank
The EU's Defence Readiness Roadmap 2030 places the Eastern Flank among its most important flagship projects and the largest recipients of SAFE funding.
NATO's eastern flank runs as a single strategic arc from the Baltic Sea to the Black Sea and into the eastern Mediterranean — one perimeter, one adversary, one logic. The Baltic states have spent a decade establishing the defence innovation infrastructure, procurement culture, and institutional relationships that the Balkans and Black Sea corridor is now developing at speed.
The eastern flank is also the stress test of European defence ambition as it concentrates the threat, the funding, and the industrial opportunity in the same geography.
