AIDC F-CK-1 Ching-kuo

The AIDC F-CK-1 Ching-kuo, commonly known as the Indigenous Defense Fighter (IDF), is a Taiwanese air superiority jet fighter with multirole capability named after Chiang Ching-kuo, the late President of the Republic of China. The aircraft made its first flight in 1989. It entered active service with the Republic of China Air Force in 1994, and all 130 production aircraft had been manufactured by 1999.

The IDF program was initiated when the United States refused to sell F-20 Tigershark and F-16 Fighting Falcon jet fighters to Taiwan following diplomatic pressure from the People's Republic of China. Taiwan therefore decided to develop an advanced indigenous jet fighter. The IDF jet fighter project was designed and built by the Aerospace Industrial Development Corporation (AIDC) based in Taichung, Taiwan, with some assistance from American defense corporations.

The AIDC officially began the IDF development project in May 1982 following the ROCAF's failure to purchase new fighters from the United States as a result of Chinese diplomatic pressure. The project was named An Hsiang and divided into four sections in 1983:

  • Yin-Yang: "Soaring Eagle". Development of the airframe. Some cooperation with General Dynamics.
  • Yun-Han: "Cloud Man". Development of the aircraft powerplant and propulsion. Cooperation with Garrett (Now Honeywell).
  • Tien-Lei: "Sky Thunder". Development of the avionics systems. Some cooperation with Smiths Industries, with some components purchased directly from Lear Astronics (today a subsidiary of BAE), Litton (today a subsidiary of Northrop Grumman) and Martin-Baker.
  • Tien-Chien: "Sky Sword". Development of air-to-air missiles.

In April 1997 American company Litton's Applied Technology division was awarded a production contract and options totaling $116.2 million by the Aerospace Industrial Development Corporation for Improved Radar Warning Receivers (IRWR) to be installed aboard.
