Development

Origins

The origins of the KT-1 can be found within the KTX programme, which had been launched during 1988 on behalf of the

Republic of Korea Air Force The Republic of Korea Air Force (ROKAF; ko, 대한민국 공군; RR: ''Daehanminguk Gong-gun''), also known as the ROK Air Force or South Korean Air Force, is the aerial warfare service branch of South Korea, operating under the Ministry of N ...

(RKAF). The programme, which sought to develop an indigenously designed trainer aircraft, was a joint effort between aircraft manufacturer

(KAI) and government body

(ADD); the latter was responsible for overseeing the project, while the former performed the detailed design work as well as the majority of manufacturing activity.

of the KT-1 took place, after which the flight testing programme formally commenced. During 1995, the aircraft was officially named 'Woongbi'. In 1998, it was announced that the final test flight had been performed. During the following year, an initial production contract was signed for eighty-five aircraft, with provisions for an additional twenty, between manufacturer Korea Aerospace Industries (KAI) and the RKAF.

Further development

During 2002, KAI revealed that they were working on the production of an upgraded and armed version of the KT-1 basic trainer. This variant, designated ''KO-1'', was intended to be used in the
