South Korea and Indonesia have opened a joint office to carry out consultations in the KF-X fighter aircraft development project.
The office has been set up in Sacheon, 437 kilometers southeast of Seoul, Yonhap News Agency reported Wednesday.
“Apart from helping both the nations exchange views on pending issues during KF-X project, the move of opening joint management program also allows them to effectively fine-tune differences,” Jung Kwang-sun director general for KF-X program Group at the Defense Acquisition Program Administration (DAPA).
South Korea and Indonesia signed an 8.1 trillion-won ($7.1 billion) deal to jointly develop the KF-X/IF-X 4.5-generation fighter in January last year, with the Jakarta investing 1.7 trillion won for a 20 percent stake in the project.
The project is led by South Korea's DAPA, with the Korea Aerospace Industries Co., the country's sole aircraft manufacturer, leading the development, the spokesman said.
Currently, Indonesia's state-owned aerospace prime, PT Dirgantara Indonesia, has sent 74 engineers and officials to KAI to participate in the development project, he said.
The preliminary design phase for the KF-X/IF-X began in December and is expected to be completed in the second quarter of 2018. A prototype is due to fly in 2021 or 2022, with deliveries scheduled for around 2025.
South Korea's military requires more than 100 KF-Xs, while Indonesia needs at least 50 IF-Xs. There will be minor differences in operating systems between the two, official sources said.
Once they become operational, the KF-X fighters are to replace South Korea's F-4 and F-5 jets. The 16-meter next-generation fighter is being built to reach speeds of up to Mach 1.97, or 2,411 kph. It can carry more advanced radar systems and electronic equipment compared to KF-16.
Seoul has beefed up its defense capabilities to better counter North Korea's nuclear and missile threats in the past decade. Last year alone, Pyongyang conducted two nuclear tests and a series of ballistic missile launches.
