Space industry in South Korea

The Korea Aerospace Research Institute (KARI), headquartered in Daejeon, South Korea, is the nation's principal government aerospace research and development organization — responsible for developing South Korea's launch vehicle technology, Earth observation satellite programs, space exploration initiatives, and aviation research, operating since May 2024 as an affiliated research institute of the Korea AeroSpace Administration (KASA). Founded in 1989, KARI's signature achievement is the Nuri (KSLV-II) launch vehicle — South Korea's first domestically designed and manufactured orbital rocket, developed entirely without foreign technology transfer assistance following U.S. restrictions on Korean launch vehicle development. Nuri is a three-stage liquid-propellant rocket powered by a cluster of 75-ton-force KRE-075 engines burning liquid oxygen (LOX) and kerosene. After a partial success in October 2021, Nuri achieved its first successful orbital launch in June 2022, placing a 1.3-ton payload into a 700km sun-synchronous orbit — making South Korea the seventh nation to independently develop and launch a 1+ ton satellite. A third launch in May 2023 successfully deployed the Next Generation Small Satellite-2 (CAS500-2) and multiple cubesats. The Korea Space Launch Vehicle (KSLV-II) program cost approximately 1.96 trillion Korean won ($1.5B USD) and employed over 300 domestic companies. KARI's KOMPSAT (Korea Multi-Purpose Satellite) program has produced a series of Earth observation satellites since KOMPSAT-1 (1999), progressing through electro-optical, SAR, and hyperspectral imaging satellites. KOMPSAT-3A provides 0.55-meter panchromatic resolution and 2.2-meter multispectral resolution; KOMPSAT-5 delivers X-band SAR imagery. KOMPSAT imagery is used for national security, disaster monitoring, urban planning, and export to international customers. KARI is developing the Korea Pathfinder Lunar Orbiter (Danuri), South Korea's first lunar mission launched in August 2022 aboard a SpaceX Falcon 9, which entered lunar orbit in December 2022 and carries a NASA ShadowCam instrument to image permanently shadowed craters. South Korea's independent launch capability and growing deep space ambitions position KARI as a rising mid-tier space agency alongside JAXA, ISRO, and CSA.

Korea Aerospace Industries

Sacheon, South Korea commercial

Korea Aerospace Industries (KAI), founded in 1999 and headquartered in Sacheon, South Korea, is South Korea's national aerospace champion and the country's largest aerospace company — established through the consolidation of Samsung Aerospace, Daewoo Heavy Industries, and Hyundai Space & Aircraft divisions — manufacturing military aircraft, trainers, helicopters, satellites, and unmanned aerial vehicles while serving as the primary contractor for South Korea's KF-21 Boramae next-generation jet fighter program. KAI's space business has grown significantly as South Korea pursues satellite manufacturing sovereignty. The company developed and integrated the Arirang (KOMPSAT) Earth observation satellites for the Korea Aerospace Research Institute (KARI): KOMPSAT-3 (2012, 70 cm optical resolution), KOMPSAT-5 (2013, SAR), and KOMPSAT-3A (2015, 55 cm multispectral) — each generation pushing South Korean optical and radar imaging capabilities toward commercial-grade resolution. KAI manufactures satellite bus structures and integration at its Sacheon facilities, with payload instruments typically sourced from KARI, ETRI (Electronics and Telecommunications Research Institute), or international partners. In launch vehicle collaboration, KAI supported the Korean Satellite Launch Vehicle (KSLV-I / Naro) program as an integration partner, and contributes to the KSLV-II Nuri rocket's stage manufacturing — with Hanwha Aerospace producing the engines and KAI contributing structural components. KAI declined to bid for the next-generation KSLV-III launcher in March 2024, leaving Hanwha Aerospace as that programme's system integrator. KAI's military aircraft programs dominate its revenue: the T-50 Golden Eagle supersonic trainer (exported to Philippines, Indonesia, Iraq, Thailand), the FA-50 light combat aircraft, the Surion helicopter, and the KF-21 Boramae stealth-capable 4.5-generation fighter (first flight 2022) intended to reduce South Korea's dependence on F-35 imports for advanced air combat.
