AIDC AT-3/T-5 Brave Eagle

The AIDC AT-3/T-5 family covers Taiwan's indigenous two-seat jet trainer line, starting with the AT-3 Tzu Chung, which first flew in 1980 and entered service in 1985, and continuing with the T-5 Brave Eagle, a next-generation advanced jet trainer delivered to the ROCAF from 2021. AIDC and ROCAF sources describe the family as a pilot-training platform that also supported Thunder Tigers aerobatics, with the T-5 replacing the older AT-3 and F-5 trainer fleet.
