'Seoul International Aerospace and Defense Exhibition (ADEX 2025)' held at Seoul Air Base and Goyang KINTEX from October 17th to 24th, 2025, is an important event showcasing the present and future of South Korea's aerospace and defense industries. This ADEX, the largest ever, will feature 600 companies from 35 countries, presenting cutting-edge weapon systems and future aerospace technologies. In particular, the development of indigenous aircraft technology is attracting global attention, and this exhibition is expected to encompass the results of research and development over the years. Beyond simple military technology, it will present a vision for future air mobility (AAM) and the space economy, presenting a blueprint for South Korea's leap toward becoming an aerospace powerhouse.
The KF-21 Boramae, the next-generation main fighter of the South Korean Air Force, is one of the biggest points of interest at ADEX 2025. The KF-21, which successfully completed its first test flight in July 2022, is scheduled to begin full-scale deployment from 2025, with 40 aircraft planned to be delivered to the Air Force by 2028. Classified as a 4.5th-generation fighter, the KF-21 is equipped with excellent maneuverability, state-of-the-art AESA radar, IRST, and EO TGP, maximizing situational awareness on the battlefield. Furthermore, it has the potential to continuously evolve through performance improvements by block, solidifying its position as an indigenous fighter optimized for the future battlefield environment. A demonstration flight of the KF-21 is scheduled at this ADEX, raising expectations among many visitors.
Unmanned Aerial Vehicle (UAV) technology is another key area to watch at ADEX 2025. Korean Air is leading the development of advanced UAVs such as the low-observable unmanned formation aircraft (Loyal Wingman) 'KUS-RP (Replicator),' and is advancing its autonomous mission performance and swarm flight control capabilities through AI pilot technology. This shows the potential of a future combat system that can be operated alongside manned fighters and perform various missions. In addition, Airbility will showcase next-generation manned and unmanned aerial vehicle solutions based on electric vertical takeoff and landing (eVTOL). In particular, the tactical small UAV 'AB-U10' has the ability for rapid close-range reconnaissance and drone threat response, and the long-range mission UAV 'AB-U60' adopts a mother ship structure that can carry small drones, presenting multi-purpose utilization possibilities.
The development of the Korean Multi-Purpose Transport Aircraft (MC-X) will also be an important topic of discussion at ADEX 2025. Korea Aerospace Industries (KAI) is researching the development of a 30-ton class multi-purpose transport aircraft that uses turbofan engines, which is expected to contribute not only to enhancing military transport capabilities but also to non-military uses such as international peace activities and disaster relief. Although some discussion is needed in the development process, it has the potential to expand into various special-purpose aircraft such as anti-submarine patrol aircraft, air-to-air refueling aircraft, reconnaissance aircraft, and electronic warfare aircraft, and is considered an essential element in strengthening future national defense capabilities. Korean Air and KAI are also engaged in fierce competition in the electronic warfare aircraft development project, which is an important step in securing core technology to neutralize enemy air defense systems and wireless command and communication systems.
ADEX 2025 also presents a vision for future air mobility (AAM). AAM, including Urban Air Mobility (UAM) and Regional Air Mobility (RAM), is at the core of the future urban transportation system, and eVTOL physical aircraft and related technologies will be on display at the New Technology Hall. Furthermore, the development of avionics technology is essential for improving the performance of indigenous aircraft. SK Telecom is announcing plans to dramatically expand the operational radius of unmanned aircraft through the development of a 'communication relay drone' that combines AI, low-frequency, and satellite communication technology, solving communication blind spots and leading innovation in military communications. These advanced avionics technologies play an important role in maximizing the autonomy and efficiency of indigenous aircraft.
This ADEX 2025 will focus on raising awareness of the space economy and promoting related industries beyond aerospace technology. The Korea Aerospace Administration (KASA), launched in January 2025, announced its 2025 business plan with the goal of 'Leaping into the Top 5 Spacefaring Nations,' and is promoting the acceleration of a private-centered space economy, securing future global technology in advance, and establishing a strategy for domestic production of aviation gas turbine engines. Various space technologies, such as reusable launch vehicle physical models, advanced satellite communications, and space-grade carbon fiber, will be on display at the New Technology Hall, which will be an important opportunity to further strengthen South Korea's space industry competitiveness.
ADEX 2025 will be a venue showcasing the remarkable achievements and bold visions for the future that South Korea has made in the aerospace and defense industries. The successful development and deployment of the KF-21 Boramae, the development of various unmanned aerial vehicle systems, next-generation transport aircraft and special-purpose aircraft, and active investment in future air mobility and space technology clearly demonstrate that South Korea is leaping towards becoming a global aerospace powerhouse. This technological innovation will not only strengthen national defense capabilities but also revitalize the domestic industrial ecosystem and have a positive impact on the 'K-Defense' entry into the global market. We invite you to directly witness the brilliant future of South Korean aerospace technology through ADEX 2025.
