South Korea\u2019s KF-21 Boramae fighter jet has officially entered the production phase, with the first mass-produced unit now in final assembly at Korea Aerospace Industries (KAI) in Sacheon Airport (HIN).\u00a0<\/p>\n
On May 20, 2025, the Defense Acquisition Program Administration (DAPA) held a ceremony to mark the start of final assembly for the first mass-produced KF-21 Boramae fighter jet.\u00a0\u00a0<\/p>\n
Since the launch of mass production in July 2024, the aircraft has advanced through various manufacturing stages, including component fabrication and the assembly of the front, center, and rear fuselage sections. Final assembly brings together the full airframe, fuselage, wings, and empennage, along with the integration of engines, avionics, and mission systems.\u00a0<\/p>\n\n
