Is it actually a new prototype or a upgraded original prototype or a upgraded production A/B?? Several flight development frames were kept.This video is about the AIDC F-CK-1 Ching-kuo upgrade program. This is a plane that is not being talked about here and there is very little information out there about this platform. Now it says in the video that the new prototype of the AIDC IDF C/D was build around 2005. But I thought that the plant closed down in 2000 after the last of the production run of 130 planes has finished. So if they can still build new prototypes from scratch in 2005 after the plant has closed. Why can't they restart the program and build more production planes ? Because right now Taiwan isn't building any new planes but simply upgrading the older ones.
The IDF would actually make a good USAF TX platform!
