Korea Aerospace Industries (KAI) is set to enhance its collaboration with Indonesia's PTDI for the KF-21 fighter jet.

Korea Aerospace Industries Co. (KAI) has announced an expansion of its partnership with Indonesia's state-owned aircraft manufacturer, PT Dirgantara Indonesia (PTDI). This agreement focuses on the production of the KF-21 fighter jet, emphasizing the strengthening of international defense ties.

The two companies signed three memorandums of understanding (MOUs) during the 12th South Korea-Indonesia Defense Industry Cooperation Committee meeting held in Jakarta. These agreements cover not only the KF-21 fighter jet but also flight simulators and commercial aircraft production.

Under the new KF-21 agreement, KAI and PTDI will collaborate on manufacturing various structural components in Indonesia, allowing PTDI to participate directly in the production process. This partnership builds on Indonesia's previous acquisitions of KAI's KT-1 basic trainer aircraft and T-50 advanced trainer jets.

KAI aims for Indonesia to become the first international customer for the KF-21, South Korea's advanced supersonic fighter jet, further solidifying the defense cooperation between the two nations.
