South Korea’s fifth-generation stealth fighter KF-21, is likely to outsell US F-35s if exported, although their power may not be comparable.
According to information on Eurasia Times website, the Indonesian side recently reiterated its commitment to participate in the South Korean – led KF-21 stealth fighter project; would provide a cheaper alternative to the US F-35 stealth fighter.
In April this year, South Korea demonstrated the prototype of its first domestically produced, semi-stealth fighter jet as the KF-21. The Indonesian side agreed to invest $7.6 billion in the project, accounting for about 20% of development costs, in exchange for the acquisition of related technologies. It is expected that Indonesia will buy 50 KF-21 stealth fighters.
The KF-21 project, which began research and development in 2015, will eventually replace the aging F-4 and F-5 fighters of the Republic of Korea Air Force. Although Indonesia has a 20% stake in the KF-21 project, its commitment to the KF-21 fighter project has been questioned, due to Indonesia’s late payment due to poor domestic economic conditions; Besides, the opinion of the leader of the Indonesian Army is often “shaken”.
