KAI KT-1 Woongbi (Hangul) "1991"

The KAI KT-1 Woongbi (Hangul: KT-1 웅비) 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.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 (RKAF). The programme, which sought to develop an indigenously designed trainer aircraft, was a joint effort between aircraft manufacturer Korean Aerospace Industries (KAI) and government body Agency for Defence Development (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.[1] Unusually, CATIA computer aided design (CAD) software was used to produce the design, being the first use of such techniques for an aircraft in its class


The Republic of Korea Air Force (ROKAF) is the primary customer for the type. During 2000, the first KT-1 Woongbi was handed over to the ROKAF; deliveries had originally been scheduled to commence two years earlier.[9] By the end of that year, eight aircraft had been delivered to the service; reportedly, a rate of production of two aircraft per month had been achieved by this point.[10] By November 2003, the assembly line was reportedly about to be put on hold following the completion of the ROKAF’s order; however, KAI aimed to restart production within two-three years based upon follow-on orders.[11][12] However, a follow-on ROKAF order for 20 aircraft was received that same month.[13] The majority of the ROKAF’s fleet can be armed with both gun pods and rockets, which are intended to be used for weapons training.[14]

One of the first export customers for the KT-1 was Indonesia. During early 2001, Indonesia exchanged 8 CASA/IPTN CN-235 transport aircraft for 12 KT-1 trainers.

On 6 November 2012, KAI and the Peruvian Air Force signed a contract for 20 KT-1Ps, comprising ten KT and ten KA versions as well as some offset and technology transfer arrangements, for an approximate amount of US$208 million. KAI was to provide the first four aircraft by the end of 2014, while the remainder were to be locally assembled by SEMAN, the maintenance air wing of the Peruvian Air Force.[27][28] The type shall progressively replace the aging fleets of Aermacchi MB-339 and Embraer EMB 312 Tucano aircraft. During April 2015, the first locally manufactured KT-1P was delivered to the Peruvian Air Force.
