Scheduled for May 20–21, 2026, Athens will host the inaugural Athens Defence Summit (ADS), an international platform aiming to address the future of warfare and strategies to defend freedom in a rapidly evolving technological landscape. Hosted by the Hellenic Ministry of National Defence and supported by various national defense organizations, this summit aims to gather key political and military leaders, as well as industry representatives, to discuss the preservation of democratic sovereignty in an era characterized by disruptive changes.

The ADS will explore crucial themes such as the impact of artificial intelligence, autonomous systems, and advanced aerospace technologies on modern conflicts. The objective is not only to assess how wars are fought but to delve into the integral role of alliances and military capabilities in ensuring national security and credible deterrence. Prominent figures in the transatlantic community and European leaders will contribute to the dialogues, emphasizing the need for robust partnerships in defense matters.

As global tensions mount and the nature of warfare evolves, the Athens Defence Summit represents a critical initiative aimed at enhancing collaboration among democratic nations. By focusing on structure, capability, and strategic alliances, the summit seeks to solidify frameworks that will assist countries in navigating future conflicts while maintaining the freedoms of their citizens. The outcomes of this summit could have significant implications for international defense policies and cooperative security measures across Europe and beyond.
