한국·인도네시아, "KF-21 시제기" 인도 최종 협상 '합의' — 조만간 구매계약 체결도 가능

South Korea and Indonesia have virtually reached an agreement on final negotiations regarding the delivery of the fifth prototype of the KF-21 (Boramae). The key point is that the details of the delivery procedures are currently being finalized, and a purchase contract is expected to be signed soon. The production volume has been reduced from 48 units at the initial stage of the project to 16 units, a third of the original amount; the delivery of the prototype is reportedly contingent on the payment of the purchase price for the 16 production aircraft. The fifth prototype is a single-seat model equipped with an AESA radar, IRST, integrated electronic warfare system, and aerial refueling capabilities. While it possesses performance nearly identical to the production model, all core modules are "black boxes," making it fundamentally impossible for Indonesia to verify or steal the technology without authorization. It is analyzed that Indonesia intends to maintain the justification and momentum for its own IFX fighter development project by securing this prototype. 📌 Key Points Final Agreement: Final coordination of delivery procedures for Prototype No. 5; expectation of signing a purchase contract (THE GURU) Production Volume: Reduced from 48 units in the initial project to 16 units; prototype delivery conditional upon payment for production aircraft Cost Breakdown: Prototype 350 billion KRW + Participation Fee 173 billion KRW + Data Costs 75 billion KRW (Equivalent to a 600 billion KRW contribution) Security Structure: Core modules such as AESA, IRST, and mission computer are fully blackboxed — source code cannot be deciphered Indonesia's Objective: To secure momentum for independent IFX fighter development and maintain the foundation of the aviation industry through the continuation of the Boramae project 📰 Source: THE GURU (June 24, 2026)
