Korea Aerospace Industries, Ltd. is a South Korean aerospace and defense company. It was originally established as a joint venture of Daewoo Heavy Industries' aerospace division, Samsung Aerospace, and Hyundai Space and Aircraft. During 1999, KAI became more independent of its founding members, acquiring their aerospace interests at the behest of the South Korean government following the financial troubles of these companies that had resulted from the 1997 Asian financial crisis.
