Taiwan has begun flight-testing the upgraded C/D version of its F-CK-1 Indigenous Defence Fighter (IDF) with a new digital flight control computer supplied by BAE Systems. The C/D is the first major upgrade of the IDF since the locally designed and developed lightweight fighter entered Taiwanese air force service in 1993.
Taiwan’s Aerospace Industrial Development Corporation (AIDC) built 130 IDFs, delivering the last A/B Ching-kuo version in 1999. The C/D upgrade, also known as Shiang-Seng, was launched in 2001, and includes additional fuel, improved avionics and electronic-warfare systems and expanded weapons capability.

Replacing the IDF A/B’s 16-bit computer, the new 32-bit processor is faster, more reliable and “integrates easily with the aircraft’s air data, avionics and head-up display systems,” says BAE, adding that Taiwan plans to use the new computer to upgrade existing IDFs “and on new-build aircraft”.
