KAI's T/FA-50 MLU Proposal announced in 2022. It was not officially created by the South Korean Ministry of Defense.

The T-50 family of aircraft has been in service for 18 years since it was first delivered to the Air Force and will reach mid-life (20 years) in 2025.

Why does the T/FA-50 require an MLU? In the meantime, aircraft components (IMDC, HUD, FLCC, CMFD, etc.) are being sourced overseas and manufacturers are discontinuing them. Last Time Buy (LTB) components are already reaching their limits.

Older avionics systems make it difficult to train pilots for the upcoming modernization of fourth and fifth generation fighters, which will lead to additional missions for combat squadrons and increased training costs, as combat units will have to designate fighters to complete limited tactical course training on trainers. Therefore, it is necessary to upgrade to the latest Avionics system and introduce a Embedded training system to fulfill the tactical training mission.

The FA-50, a light fighter, has the same problem. The L/M version of the AIM-9 series, the main weapon, has been discontinued, and the AGM-65 is too old to be used in the current battlefield. There is also the problem of the mission computer mentioned above, and the radar required for the future battlefield needs to be applied. Sensor pods for precision strikes, external fuel tanks to increase the mission radius, aerial refueling capabilities, and rear fuselage modifications are ways to improve this. It should also be capable of carrying Korean short- and medium-range air-to-air missiles, which were developed in the 30s.

This is the part that points out that overseas countries legislate the performance improvement cycle of the aircraft in operation and start the business when that time is reached, while Korea does not. In the end, the KT-1 missed the time for MLU and had to promote new development, and the T/FA-50 still has a chance, so we should not miss this time and promote MLU.

This part analyzes the requirements for improvements to the T/FA-50 by analyzing requirements from the KF-16 and the APT T-X program, a U.S. Air Force advanced training aircraft program. The KF-16 was upgraded to improve survivability, requiring protective equipment such as RWR/CMDS, GCAS, PARS, and TF, and to extend the life of the aircraft by modernizing aviation avionics, overhauling and reinforcing the airframe, while the APT T-X's requirements include aerial refueling capability, LAD, SFI, and integration of embedded training system capabilities.

Therefore, KAI proposed a plan to integrate aviation avionics, FLCC, and embedded training systems in common with T/FA-50 to improve internal fuel expansion of the 300G/L external fuel tank integrated fuselage for mission radius expansion, gas life extension, GCAS, TCAS, PARS, and individually apply specific performance improvement factors.

This is a detailed shape for each performance improvement element. I think it will be understandable just by looking at the picture without having to explain it separately.
