DEFEA – Defence Exhibition Athens Athens

DEFEA – Defence Exhibition Athens is an international trade fair that has established itself as a specialized platform for professionals from the armed forces, security agencies, and the defense industry. Since its debut in 2021, the exhibition has been held biennially at the Metropolitan Expo – Greece’s largest and most modern exhibition center, located near Athens International Airport. The event is organized by ROTA Exhibitions Greece, an experienced organizer with extensive expertise in international B2B events.

Exclusively open to trade visitors, DEFEA showcases cutting-edge technologies and systems in land, air, and naval defense, national security, and cybersecurity. The event brings together leading companies in the global defense sector with high-ranking decision-makers, government officials, and military delegations. The focus is on the latest advancements in defense technology, ranging from armored vehicles and weapon systems to reconnaissance technologies and digital security solutions.

A defining feature of DEFEA is its strategic role in enhancing Greece’s defense and security posture in Southeastern Europe and the Eastern Mediterranean. As an active NATO member with one of the highest defense budgets in the region, Greece leverages the exhibition to foster international cooperation—both within the alliance and with non-NATO countries. Athens thus becomes a hub for strategic dialogue, security policy exchange, and technological innovation. The event’s conferences and seminars further provide a forum for in-depth discussions on global security challenges.

With its strategic location at the crossroads of Europe, Asia, and Africa, its state-of-the-art exhibition facilities, and its growing geopolitical relevance, DEFEA has become a key meeting point for the international defense community—while simultaneously enhancing Athens’ profile as a forward-looking, security-focused capital.

The DEFEA – Defence Exhibition Athens will take place on 3 days from Tuesday, 18. May to Thursday, 20. May 2027 in Athens.
