IDEF 2027 – the 18th International Defence Industry Fair will bring together the global actors of the defence and security ecosystem at the Istanbul Expo Center on 3–9 May 2027.
Hosted by the Ministry of National Defence of the Republic of Türkiye, supported by the Presidency of Defence Industries of the Republic of Türkiye, held under the management and responsibility of the Turkish Armed Forces Foundation, and organized by KFA Fuarcılık A.Ş., IDEF 2027 stands as a global platform where the most advanced defence and security technologies—primarily land, naval, and air systems—will be showcased.
Ranked among the world's most prestigious defence industry events, IDEF brings together state representatives, military and civilian delegations, decision-makers, defence industry companies, and technology developers under one roof, fostering strategic and sustainable cooperation.
Through panels, seminars, signing ceremonies, and product launch events held throughout the fair, IDEF aims to enhance sectoral knowledge sharing and strengthen engagement among defence industry stakeholders.
IDEF 2025, held with record-breaking figures, hosted 1,491 companies from 49 countries, 229 official delegations from 100 countries and international organizations, and more than 120,000 visitors from 114 countries—once again demonstrating its prestigious and strategic position within the international defence industry ecosystem.
Building on the strong momentum achieved in 2025, IDEF 2027 aims to set a new benchmark in international defence cooperation while contributing to Türkiye's defence industry vision and its high-technology-driven production capacity. By generating renewed momentum in global defence partnerships, the fair will continue to position Istanbul as one of the key meeting hubs of the global defence industry in 2027.
