The prototype of the KF-21 fighter developed by South Korea, prototype No. 5, made its first flight on May 16. The South Korean-developed KF-21 fighter, the No. 5 aircraft, has the same livery as the KF-16 fighter of the South Korean Air Force. Although the KF-21 fighter developed by South Korea is twin-engined, looking at the ratio of the pilot to the fuselage of the South Korean Air Force, it feels that the fuselage is not large, just a medium-sized aircraft. The KF-21 fighter developed by South Korea, the project management ability is good enough, in just a few years, the first flight of 5 aircraft, 6 manufacturing tasks. It is said that the KF-21 fighter developed by South Korea, the No. 5 prototype, will be sent to Indonesia and converted into a version suitable for the Indonesian Air Force, which will be delivered to the Indonesian Air Force for test flights. Indonesia plans to buy 50 KF-21 fighters. At present, the KF-21 fighter has completed more than 200 test flights and 260 flight test subjects. It is expected to start mass production next year and fully equip the ROK Air Force by 2026 to form combat effectiveness. After all, South Korea's KF-21 fighter progress is so fast, and the J-35 fighter itself flew many years earlier than the KF-21 fighter from the FC-31 fighter project, and now the progress lags behind the South Korean KF-21 fighter. Now it is necessary to speed up and increase the production of J-35 fighters, and we must not hesitate.
