So how will this end for Indonesia, will they be kicked out?
No. It's highly unlikely. Officials involved KF-X/IF-X have said that cooperation will continue whenever asked about the relationship with Indonesia.
Even after this incident.

An extraordinary report in defensenews...

MANILA, Philippines — South Korea will build 40 KF-21 Boramae fighter jets this year with the 238.7 billion won (U.S. $178.6 million) allocated for the Defense Ministry, even as the aircraft makes its way through flight and ground tests.


I wonder if this is inaccurately reported or mistranslated or if there is a typo (4 jets to be built this year, not 40).

An extraordinary report in defensenews...

The Defensenews journo got the story wrong and other media now spreading the wrong numbers.

Initial production volume KF-21:
40x Block I (air superiority) 2026-2028
Second production volume KF-21:
80x Block II (multi-role) 2029-2032

120 units in total for ROKAF.


Early Nov. 2023 the Korea Institute for Defense Analyses (KIDA) recommended in a business feasibility study to reduce initial numbers of Block I from 40 to 20 and to wait for successful air-to-ground performance tests to additionally produce 20 units in Block II configuration.

This report resulted in a parliamentary controversy with the opposition party demanding to stick to former „original“ production plans. Mudslinging between ruling conservatives and opposing liberals. Unfortunately the criticized KIDA director in charge of the study passed away in late Dec. 2023

Now they’re sticking to the „original“ plan of 40 units for initial production volume without waiting for air-to-ground performance validation.
So the partial amount of 238.7 billion won (~$178 million) in the defense budget 2024 reflect the calculation with total costs for 40 units til 2028 in mind.

Doesn‘t mean you can get 40 KF-21 produced in 1 year for a lump sum of $178 million. That would be a dream come true 😁

KF-21 fighter jet successfully completes aerial refueling test​


Without music:


Korea's supersonic KF-21 fighter jet successfully completed an aerial refueling test expanding its operational radius for the first time on Tuesday.

The Defense Acquisition Program Administration (DAPA) announced Tuesday that KF-21 prototype No. 5 took off from the 3rd training airfield in Sacheon, South Gyeongsang that morning and succeeded in an aerial refueling flight over waters off Korea's southeastern coast. The KF-21 fighter jet is set to be deployed in 2026.

The Air Force’s KC-330 tanker aircraft connected a refueling rod to the KF-21 and injected fuel into the fighter jet while flying.

The refueling test examined how turbulence during aerial refueling affects the operation of the KF-21, and whether the connection and separation of the tanker and the KF-21 can be done safely.

Aerial refueling increases the endurance time of a fighter jet by increasing how long it can fly and how many bombs it can carry.

“Although it can vary by timing and quantity, one aerial refueling is expected to increase the operational radius by about 50 percent," DAPA said Tuesday. “Aerial refueling can expand the operational radius and operating time of the KF-21, maximizing operational effects such as long-distance mission capabilities and the combat power of the Air Force.”

“We plan to continue verifying the KF-21’s aerial refueling capabilities at various altitudes and speeds about 60 times until March 2025,” said Noh Ji-man, head of the DAPA’s Korean fighter project division.

A total of six prototypes of the KF-21 have been built. They passed tests on assorted capabilities such as supersonic flight and air-to-air weapon separation to qualify as provisionally suitable for combat. The first production model of the KF-21 will be delivered to the Air Force in the first half of 2026.

The development project for the KF-21 was launched in 2015 jointly with Indonesia in order to develop a supersonic fighter jet to replace the Air Force’s F-4 and F-5 jets.

It hasn't been a smooth process for the jet. The police are currently investigating the alleged technology data theft related to the KF-21 after DAPA, the Defense Forces Counterintelligence Command and the National Intelligence Service jointly held an internal investigation into two Indonesian engineers involved in the project.

The engineers were first caught on Jan. 17 trying to leak KF-21 data by smuggling out a USB device from the KAI headquarters. The police stepped into the investigation on Feb. 22 and raided the Korean Aerospace Industries offices last week.

The two suspects are currently prohibited from leaving the country.

Indonesia promised to pay 20 percent of the $6.5 billion funding for the KF-21, but Jakarta has been delaying payments.

DAPA reaffirmed on Tuesday that Indonesia must complete its payment for the project by 2026.

"There is no change in our stance," an official from DAPA said.

Edit: corrected wrong Indonesian cost share sum in article.

Successful extreme weather conditions and environmental simulation test of KF-21 004 prototype:

  • simulation of low temperature, rainfall, icing
  • waterproofing and anti-icing performance test on the ground

Until now, it has been testing the stability of the aircraft and missile operation by flying at a low speed of 400 to 800 kilometers per hour, and it was confirmed that it exceeded Mach 1.8 of the top speed of the aircraft for the first time in a test flight on May 2.

On May 8, the South Korean Defence Acquisition Program Administration (DAPA) conducted a successful test of the Meteor long-range air-to-air missile from the KF-21 Boramae fighter jet.

.
Additionally, DAPA also confirmed the successful testing of the IRIS-T short-range air-to-air missile on the same day, further showcasing the KF-21’s versatile armament capabilities. The KF-21 Boramae is now the fourth aircraft type to be integrated with the Meteor missile, following the Rafale, Eurofighter, and Gripen.

Related photos and videos have not been released yet, but they are expected to be released soon. During the missile launch test, there is no video taken from the outside aircraft, but only video taken from inside KF-21.

Excellent news, meteor is extremely potent addition to the arsenal.

Is Korea working on its own A2A missile programs?

Iirc, They showed a similar mock up to Meteor. Only slightly larger. 200mm body for the BVR weapon and 400mm body for AShM.

I heard that the short-range air-to-air guided missile started planning in 2023 and will be completed by CDR in 2028. The long-range air-to-air guided missile started planning this year and is expected to be completed by the early 2030s.

Considering that both programs are scheduled to end in 2035, I think this image is an intuitive representation of the Korean air armament plan.

The CG of a South Korean mid-range air-to-air guided missile has been publicly available since 2020. It was published in ADD's own magazine when introducing the development strategy. Like Meteo, it applied Ducted Ramjet. Please note that the CG is only an approximate shape.
