The first test flight was conducted on 19 July 2022, with manufacturing scheduled to begin in 2026. It was officially given the name Boramae ( Korean: 보라매, "young hawk" or "fighting hawk"). In April 2021, the first prototype was completed and unveiled during a rollout ceremony at the headquarters of KAI at Sacheon Airport. The KAI KF-X is South Korea's second domestic fighter jet development program, following the FA-50. Indonesia took a 20% stake in the program in 2010, and the remaining 20% are held by private partners including the manufacturer Korea Aerospace Industries (KAI). The program is led by the South Korean government, which holds 60% of the program's shares. The airframe is stealthier than any fourth-generation fighter, but does not carry weapons in internal bays like fifth-generation fighters, though internal bays may be introduced later in development. The KAI KF-21 Boramae (formerly known as KF-X) is a South Korean-led fighter aircraft development program with the goal of producing an advanced multirole fighter for the South Korean and Indonesian air forces.
