The KAI KF-21 Boramae is South Korea's first indigenously designed and built supersonic combat aircraft, a twin-engine multirole fighter intended to replace ageing F-4 Phantoms and F-5 Tigers in Korean Air Force service. It represents a major leap in South Korean aerospace capability.

WEFT is AircraftIQ's four-point recognition method — how it works.

Spot it by:

A large twin-engine fighter with a broad delta-like wing, diverterless supersonic inlets, and a general aerodynamic configuration reminiscent of the F-22 and Eurofighter Typhoon, though conventionally configured. The Korean markings and overall size distinguish it.

History

Developed under the KF-X programme beginning in 2015 with Indonesian co-investment, the KF-21 first flew in July 2022. It is designed to be produced in two blocks, with Block I providing external weapons carriage and Block II adding semi-internal weapons bays for reduced radar signature.

Variants

Block I is the initial production standard with external stores; Block II will introduce semi-conformal/internal weapons carriage. A two-seat KF-21B trainer variant is also planned.

Where you'll see it

In development for the Republic of Korea Air Force with first deliveries expected in the late 2020s; Indonesia is a partner nation with planned purchases.
