The Korean Air KF-5F "Jegong-Ho" lightweight Advanced Jet Trainer (AJT) is nothing more than the American Cold War-era Northrop F-5F "Tiger II" fighter / supersonic trainer aircraft. The designation signifies a locally-produced F-5F for the Republic of Korea Air Force (RoKAF) and the type was first introduced during September of 1982. Twenty airframes were acquired in this fashion. Similarly, the KF-5E are F-5E models also built in South Korea for its air service. Introduction was also had in September of 1982 and 48 airframes were procured by the branch.
The KF-5F and KF-5E models joined F-5A/B variants purchased in 1965 by the RoKAF. F-5E models then followed in August of 1974. This experience led to local production of the type from 1982 to 1986.
For intents and purposes, the South Korean fighters are faithful to the original American design. They seat two in tandem under independent canopies and each position has ejection seats. The cockpits are set aft of a radar-housing nose assembly. The monoplane wings are held low against the sides of the fuselage and each wingtip is usually reserved for short-ranged air-to-air missiles (if armed). The tail unit comprises a single vertical fin with low-set, all-moving horizontal planes to round out the control scheme. Side fuselage intakes aspirate the turbojet engine pairing within. A retractable tricycle style undercarriage allows for the needed ground-running.
As fighters "first", Tiger IIs have a limited ground attack capability. A jettisonable fuel tank is typically fitted at centerline. As Advanced Jet Trainer platforms, they excel in providing pilots their first taste of supersonic flight.

monoplane / low-mounted / swept-back
Design utilizes a single primary wing mainplane; this represent the most popular mainplane arrangement.
Mainplanes are low-mounted along the sides of the fuselage.
The planform features wing sweep back along the leading edges of the mainplane, promoting higher operating speeds.
