Korea Aerospace Industries’ Sacheon headquarters is the company’s principal aircraft and space site, with development, manufacturing, final assembly, flight-test and sustainment capabilities. KAI’s current business pages cover the KF-21, FA-50/T-50 and KT-1 fixed-wing aircraft, helicopters, UAVs, satellites, launch vehicles and commercial and military aerostructures; its production infrastructure includes composite processing, structural manufacturing, final assembly and painting. KAI’s Aviation Center materials describe exhibition, education, outdoor-learning and factory-tour activities, while the company links the separate KAI Aerospace Museum from its main site. This is an operating aerospace and defense headquarters rather than a walk-in museum; confirm current program access with KAI. Visitor location: 78, Gongdanro 1-ro, Sanam-myeon, Sacheon-si, Gyeongsangnam-do, Republic of Korea.
