On 15 July 2010, a partnership was made with Indonesia, which would provide 20% of the funding for the KF-X project, cooperate with technological development through state-owned Indonesian Aerospace, and purchase 50 of the approximately 150–200 aircraft anticipated to be produced. Turkey had also considering joining with a 20% share, but wanted more control than South Korea had offered. The South Korean government committed to 60% of the cost. The remaining 20% was provided by domestic and foreign companies. Korean Aerospace Industries (KAI) won the production bid, and partnered with Lockheed Martin for technological support. The contract formed a plan for delivery of the aircraft to begin in 2026.
