KAI KF-21 Boramae

The KAI KF-21 Boramae/Fighting Hawk (formerly known as KF-X) is a joint South Korean/Indonesian 4.5 generation fighter aircraft development program with the goal of producing an advanced multirole fighter for the South Korean and Indonesian air forces. The airframe is stealthier than other fourth-generation fighters, but does not carry weapons in internal bays like fifth-generation fighters, though internal bays may be introduced later in development.[4] The program is led by the South Korean government, which holds 60% of the program's shares. Indonesia took a 20% stake in the program in 2010, and the remaining 20% is held by private partners including the manufacturer Korean Aerospace Industries (KAI). The KAI KF-X is South Korea's second domestic fighter jet development program, following the FA-50.
