KF-21 Boramae — 2 museum-grade prints, engineered to a wall. The KF-21 Boramae — formerly developed under the KF-X programme — is South Korea's second indigenous fighter after the FA-50/T-50 family and positions the nation among the few states capable of designing a twin-engine multirole airframe with semi-stealth avionic architecture. Korea Aerospace Industries and the Agency for Defense Development shaped a canard-less delta with partially embedded weapons carriage, AESA radar, and a defensive-aids suite aimed at air superiority and precision strike between Block I and future Block III internal-bay stealth goals. The KF-21 Boramae programme represents South Korea's most ambitious indigenous military aircraft project — a twin-engine fighter designed to reduce dependence on US-built F-16 production lines while complementing ROKAF F-35A stealth capabilities. First flight on 19 July 2022 marked Korea as one of few nations developing clean-sheet fighters in the 2020s alongside Turkey's KAAN and India's AMCA ambitions.
