The Republic of Korea and YIDEX

We sincerely welcome you to the 2026 Yi Sun-sin Defense Industry Exhibition (YIDEX), where the present and future of Korea’s defense industry come together in one place.

YIDEX has grown into a leading defense industry exhibition, held at the Republic of Korea Naval Academy, a venue unparalleled anywhere in the world.
Here, visitors can experience the technological capabilities of the maritime defense industry within an environment closely connected to real naval operations.

The 2026 YIDEX goes beyond a conventional exhibition.
It showcases the key technologies and industrial ecosystem shaping the future battlefield, including maritime and naval systems, manned-unmanned integrated systems, defense AI, advanced weapon systems, and defense manufacturing technologies.

Through exhibitions, academic sessions, and business programs linked to actual naval infrastructure, YIDEX provides a platform for meaningful exchange, where domestic and international defense industry stakeholders can engage in on-site discussions on technology, strategy, and future cooperation.

The 2026 Yi Sun-sin Defense Industry Exhibition offers a firsthand look at Korea’s defense industry as it moves beyond participation toward a leading role on the global stage.

We look forward to your interest and participation.

Thank you.
