KAI KF-21 Boramae
South Korean advanced multirole fighter aircraft
The KAI KF-21 Boramae (Korean: KF-21 보라매; lit. 'KF-21 Hunting 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.
The Block I program is led by the South Korean government, which holds 60% of the shares. An additional 20% is held by the manufacturer Korea Aerospace Industries (KAI), with Indonesia holding the final 20% stake. Later, in August 2024, Indonesia's stake was reduced to 7.5% due to a request from the Indonesian government. The Block II program, which focuses primarily on the serial integration of air-to-ground and air-to-ship armaments, will be executed alongside new international partners through early 2027. This collaborative approach will extend into the Block III (KF-21EX) program, which is also set to be carried out with newly formed global partnerships.

Why this record matters
“KAI KF-21 Boramae” is worth following because a concise public description often conceals a longer documentary argument. Here, KF-21, Boramae and South provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 23, 2026. The linked authority identifier is Q495218. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2024 and 2027.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
