The KAI KT-1 Woongbi is a Korean single-engined turboprop, basic training aircraft.
It was jointly developed by Korean Aerospace Industries (KAI) and the Agency for Defence Development (ADD).
The KT-1 is the first completely indigenous Korean aircraft ever developed.
Prototype primary trainer each with a different engine fitted, six built.
KTX-1 turboprop trainer in 1988, and the first prototype flew in 1991.
The first two prototypes were powered by the 550-shp. Pratt & Whitney Canada PT6A-25A turboprop.
KT-1 is the basic trainer of the ROKAF.
Compared to the KTX-1 prototype, the KT-1 is bigger, heavier, the tail surfaces are relocated and it has a more powerful P&W Canada PT6A-62.(950-shp)
An armed advanced trainer with light-attack and forward air control capabilities.
Several new features unique to the KA-1 are a head-up display and up-front control panel, MFD panels, and five hard points, two under each wing and one under the fuselage.
The hard points may be equipped with rocket launchers, gun pods or AIM-9 Sidewinder missiles.
