The KAI KF-21 Boramae (Korean: KF-21 보라매; lit. 'KF-21 Fighting Hawk'; formerly KF-X; commonly KF-21) is a South Korean twin-engine fighter aircraft. The initial goal of the program was to develop an indigenous multirole fighter for the Republic of Korea Air Force (ROKAF). The airframe of Blocks I and II adopts semi-stealth technology with partially embedded external weapons and MUM-T (Manned-Unmanned Teaming) capabilities, while full stealth—including internal weapons bays—is planned for the Block III or KF-21EX variant. As South Korea's second domestic fighter jet development program following the FA-50 series, the KF-21 makes the nation the fourth in the world—joining the United States, China, and Russia—to produce an aircraft featuring stealth avionic architecture.
