Korea Aerospace Industries

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 is also developing the Korean Space Launch Vehicle Next Generation (KSLV-III) which aims for reusable first-stage architecture.

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.
