Indonesia has a long history of developing military and small commuter aircraft as the only country in Southeast Asia to build and produce aircraft. With its state-owned company, the Indonesian Aerospace (''PT. Dirgantara Indonesia''), Indonesia has provided components for Boeing and Airbus. The company also collaborated with EADS CASA of Spain to develop the CN-235 that has seen use by several countries. Former President B. J. Habibie played a vital role in this achievement. Indonesia has also joined the South Korean programme to manufacture the fifth-generation jet fighter KAI KF-X.
