HISTORY: The AT-3 Tzu Chung was AIDC's second indigenous design to enter Taiwanese service behind the turboprop powered Chung Tsing, and serves with the Taiwanese Air Force as an advanced/ weapons trainer and light attack and close support aircraft. Up until the development of the Chung-Kuo fighter, the AT-3 was the most advanced aircraft to be developed by Taiwan's emerging aircraft industry.
 Serious design of the AT-3 began in 1975 with the placement of a development contract. The first of two prototypes flew for the first time on September 16 1980, while the first production aircraft flew on February 6 1984. In all, AIDC built 60 AT-3s for the Republic of China Air Force, the last of which was delivered in 1990.
 All 60 production aircraft were designated AT-3. The AT-3A Lui Meng meanwhile was a single seat dedicated light ground and maritime attack development. Two prototypes were known to have been built (the first one being converted from a two seat AT-3) and flown in the late 1980s, but the aircraft's current status is unclear, with development thought to have been suspended.
 The AT-3A could have been suspended in favour of the two seat AT-3B, which features the nav/attack system initially developed for the Lui-Meng. Twenty AT-3s were converted to AT-3B standard which features a Westinghouse AN/APG-66 radar and an internal weapons bay that can carry semi recessed machine gun packs. The aircraft can carry a variety of weaponry, including wingtip mounted infrared guided AAMs, in addition to bombs and rockets on four underwing and a centreline pylon. The AT-3B's maximum external stores load is 2720kg (6000lb).
 Power for the AT-3 is supplied by two Garrett TFE731 turbofans, while the airframe is of conventional construction. Other features include zero/zero ejection seats and the ability to carry and deploy an aerial target towing system.
