The AIDC F-CK-1 Ching-Kuo, commonly known as the Indigenous Defence Fighter (IDF), is a multirole combat aircraft named after Chiang Ching-Kuo, the late President of the Republic of China.
The aircraft made its first flight in 1989.
All 130 production aircraft were manufactured by 1999.
The Republic of China initiated the IDF program when the United States refused to sell them F-20 Tiger shark and F-16 Fighting Falcon jet fighters following diplomatic pressure from China.
The Republic of China therefore decided to develop an advanced indigenous jet fighter.
The Aerospace Industrial Development Corporation (AIDC), based in Taichung, the Republic of China, designed and built the IDF jet fighter.
