The KF-21 is a milestone for South Korea, which has until now fully relied on foreign-made fighter jets to meet its defense needs.
But the advanced aviation systems and parts of the KF-21 are being developed and produced locally.
Our Kim Ji-yeon reports.
The whole process of making South Korea's first homegrown fighter jet, the KF-21 Borame, from start to finish, including its design to production has been led by local technicians with locally developed technology.
The length of the new fighter jet is nearly 17 meters, its width is around 11 meters and height around five meters all-in-all it's slightly bigger than the U.S.'s F-16 fighter jets.
With a maximum payload of seven,700 kilograms, the KF-21 is known to be able to fly 22-hundred kilometers per hour.
Its range is two,900 kilometers and is equipped with air-to-ship missiles.
Other than being able to engage in midair combat it can also disarm enemy advances via land and sea as well as destroy enemy's air defense networks.
Meanwhile, Korea is also preparing for the new warplane to be able to be equipped with supersonic air-launched cruise missiles dubbed as a "game-changer" in war tactics.
The fighter jet is equipped with locally developed state-of-the-art aviation electronics equipment.
This includes the Active Electronically Scanned Array or AESA radar system which are the eyes of the aircraft enabling the jet to detect and track multiple targets simultaneously.
The beam of the radio waves is electronically steered to point in different directions without the need to move the antenna.
The radar system is crucial in the identification of enemy forces during aerial warfare, and also enables fighter jets to track enemy forces during ground surveillance.
The jet's AESA radar unit has been locally developed since 2016.
Its developers aim to meet the requirements of the South Korean military equivalent to that of U.S.'s F-16 fighter jets, which are able to simultaneously detect up to 10 objects from 50 to 60 nautical miles away.
With the rollout of the KF-21, South Korea has become the 13th country in the world to produce its own fighter jets equipped with advanced tech and radar systems.
