KAI KF-21 Boramae

The KAI KF-21 Boramae (formerly known as the KF-X) is a joint Korean/Indonesian 4.5 generation multirole fighter aircraft development program with the goal of producing an advanced multirole fighter for the Korean and Indonesian air forces. The airframe is stealthier than other 4th generation fighters, but does not carry weapons in one or more internal bays like 5th generation fighters. The program is led by South Korea, which holds 80% of shares. Indonesia joined in 2010 for 20%, and the remainder is held by private partners including manufacturer Korean Aerospace Industries (KAI). The KAI KF-X is South Korea's second domestic fighter jet development program, following the FA-50.

The KF-X development program is also known as Boramae (Korean: 보라매, literally 'young hawk' or 'eyas'), and in Indonesia is referred to as IF-X. The first prototype was completed and unveiled in April 2021 with the name KF-21 Boramae. The first test flight is anticipated in 2022, with manufacturing scheduled to begin in 2026. Forty aircraft are planned to be delivered by 2028, with South Korea expecting to deploy a total of 120 of the aircraft by 2032. It also will be available for export market.
