The KAI T-50 Golden Eagle (골든이글) is a family of South Korean supersonic advanced jet trainers and light combat aircraft, developed by Korea Aerospace Industries (KAI) with Lockheed Martin. The T-50 is South Korea's first indigenous supersonic aircraft and one of the world's few supersonic trainers. Development began in the late 1990s, and its maiden flight occurred in 2002. The aircraft entered active service with the Republic of Korea Air Force (ROKAF) in 2005.

The T-50 has been ordered by a number of countries and entered into service in some of them. Iraq ordered 24 planes in a T-50IQ variant in 2013, and received them in 2016. The TA-50 light attack variant have also been ordered by Indonesia in 2011, with 16 planes entering Indonesian service by 2014; an additional 6 were ordered in 2021. The Philippines ordered 12 units of the FA-50 light fighter variant in 2014, delivered over the next few years, and the country is considering ordering another batch of 12 planes. Thailand ordered 12 units of the T-50 advanced trainer variant (T-50TH) starting in 2015. In 2022, Poland ordered 48 FA-50s.

The KF-16 is a South Korean multi-role fighter. It is a license-produced version of the American F-16. It was locally produced by Korea Aerospace Industries (KAI). Production began in the early 1990s. A total of 140 KF-16 aircraft were produced. These aircraft are based on American F-16C (single seat) and F-16D (two seat) Block 52 aircraft. The first KF-16 fighters were delivered to the South Korean air force in 1994. At the time it was a modern warplane. The last aircraft was delivered in 2003. Today this aircraft is actively used in South Korea.

   While looking just like the F-16, the KF-16 has some changes to meet local requirements.

The KF-16 has air-to-air and ground-attack capabilities. Furthermore it can fly in all weather conditions and carry smart weapons. This multi-role fighter has 7 hardpoints and 2 wing tip mounts. These mounts are used to carry AIM-9 Sidewinder short-range air-to-air missiles. The KF-16 can also carry beyond visual range air-to-air missiles, such as AIM-120 AMRAAM, or air-to-surface missiles such as AGM-65D, cruise missiles, or anti-ship missiles. This fighter can also carry free-fall or precision-guided bombs, Joint Direct Attack Munition (JDAM), rocket pods, or fuel tanks. There is an integral M61 Vulcan 20 mm 6-barrel cannon.

   The KF-16 has limited air defense suppression capability. This aircraft has a provision of the HARM targeting system pod.

   This South Korean aircraft has an APG-68(V)7 multi-mode radar. Other features include a wide-angle Head-Up Display (HUD). This aircraft carries chaff/flare dispenser for self-defense against incoming missiles. The KF-16 also has a radar jamming system.

   The KF-16 is powered by a single Pratt & Whitney F100-PW-229 turbofan engine. This engine is fitted with an afterburner and generates 79 kN of dry thrust and 129.4 kN with afterburning. This engine powers late models of the F-16 and F-15E Strike Eagle.

   Despite its age the KF-16 is still actively used by the South Korean air force. There are plans to upgrade this aircraft with modern systems, such as new radar, armament, mission computers, electronic systems and cockpit instruments. It would improve its combat capabilities. In 2014 a deal between South Korea and BAE Systems was announced to upgrade some 134 KF-16 fighters, however later South Korean government cancelled it. In 2015 it was announced that Lockheed Martin company was selected to carry out upgrades. So if this deal comes through, the aircraft will be upgraded to the F-16V standard.

The F-15K Slam Eagle (Korean: F-15K 슬램 이글) is a derivative of the F-15E, operated by the Republic of Korea Air Force. Several major components were outsourced to South Korean companies under an offset agreement, wherein South Korea was responsible for 40% of production and 25% of assembly. The fuselage and wings are supplied by Korea Aerospace Industries, flight control actuator by Hanwha Corporation, electronic jammer and radar warning receiver by Samsung Thales, head-up display, airborne communication system, and radar by LIG Nex1, and engines by Samsung Techwin under license before final assembly at Boeing's St. Louis facility.

The F-15K has several atypical features to the F-15E, such as an AAS-42 Infra-red search and track, a customized Tactical Electronics Warfare Suite to reduce weight and increase jamming effectiveness, cockpit compatibility with night vision devices, ARC-232 U/VHF radio with Fighter Data Link, and advanced APG-63(V)1 mechanical-scanned array radar. The APG-63(V)1 radar has common digital processing equipment with the APG-63(V)3 AESA radar, and can be upgraded to an AESA radar via antenna replacement. The F-15K is equipped with the Joint Helmet Mounted Cueing System and weapons such as AGM-84K SLAM-ER, AGM-84H Harpoon Block II, and KEPD 350.

The KAI KF-21 Boramae (formerly known as KF-X) is a South Korean-lead 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 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 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% are held by private partners including the manufacturer Korea Aerospace Industries (KAI). The KAI KF-X is South Korea's second domestic fighter jet development program, following the FA-50.

In April 2021, the first prototype was completed and unveiled during a rollout ceremony at the headquarters of KAI at Sacheon Airport. It was officially given the name Boramae (Korean: 보라매, "young hawk" or "fighting hawk"). The first test flight was conducted on 19 July 2022, with manufacturing scheduled to begin in 2026. At least 40 aircraft are planned to be delivered by 2028, with South Korea expecting to deploy a total of 120 of the aircraft by 2032. It will also be available for export market.

In Indonesia, the KF-X development program is referred to as the IF-X program. The Jakarta Globe reported that the completed aircraft will receive the designation F-33.

The origins of the KT-1 can be found within the KTX programme, which had been launched during 1988 on behalf of the Republic of Korea Air Force (RKAF). The programme, which sought to develop an indigenously designed trainer aircraft, was a joint effort between aircraft manufacturer Korea Aerospace Industries (KAI) and government body Agency for Defence Development (ADD); the latter was responsible for overseeing the project, while the former performed the detailed design work as well as the majority of manufacturing activity. CATIA computer aided design (CAD) software was used to produce the design.

A series of nine prototypes were constructed, the first being complete during June 1991. During November 1991, the maiden flight of the KT-1 took place, after which the flight testing programme formally commenced.[citation needed] During 1995, the aircraft was officially named 'Woongbi'. In 1998, it was announced that the final test flight had been performed. During the following year, an initial production contract was signed for eighty-five aircraft, with provisions for an additional twenty, between manufacturer Korea Aerospace Industries (KAI) and the RKAF.

The Republic of Korea Air Force (ROKAF) purchased F-5A/Bs in 1965, and it purchased F-5Es in August 1974. KF-5 variants were built by Korean Air under license between 1982 and 1986.

The F-5E/Fs and KF-5E/Fs were to be replaced by FA-50s and after 2001, by the plans to eventually field the Korean F-X Phase 3.
