  • South Korea's KF-21 Boramae "Fighting Hawk" made its first supersonic flight in January.
  • The KF-21 is a fourth-generation airframe, but it has radar-evading capabilities like those of fifth-gen jets.
  • Roughly 65% of the KF-21's parts are domestically produced, a major feat for South Korea.

In January, South Korea's KF-21 Boramae "Fighting Hawk" successfully completed its first supersonic flight, showcasing the increasing strength of the ROK's Air Force.

The test was carried out by the 3rd Flying Training Wing of the Republic of Korea Air Force, or ROKAF, near the Sacheon airport in the country's south.
