On Feb. 22, Air Force Chief of Staff Gen. Son Seok-rak celebrated the arrival of the KF-21 supersonic fighter at Yecheon Air Base with visible enthusiasm, raising both thumbs and smiling broadly just a day after three South Korean soldiers were injured in a suspected North Korean wooden box landmine explosion. The public display by a top military leader immediately drew sharp internal criticism across military circles for clashing sharply with the severe security environment.
The controversy centers on a two-minute video distributed by the Air Force on Feb. 22 showing Gen. Son, a 40th Air Force Academy graduate, smiling, baring his teeth, and applauding as the domestic supersonic fighter touched down on the runway. This celebration occurred immediately following a landmine blast on Feb. 21 that wounded three soldiers near the Demilitarized Zone along the Military Demarcation Line in Paju, Gyeonggi Province.
North Korea had ratcheted up tensions over consecutive days by launching a hypersonic short-range ballistic missile on Feb. 20, crossing the Military Demarcation Line in the eastern sector on Feb. 21, and sending a MiG-class fighter south alongside test-firing a 240mm multiple rocket launcher on the morning of Feb. 22. These actions continually tested South Korea’s defense posture right up to the moment of the Air Force event at Yecheon Air Base, home to the 16th Fighter Wing.
Aggressive Promotion and Contrasting Official Visits
Air Force officials distributed three successive press releases regarding the KF-21 handover to Ministry of National Defense press pool reporters on Feb. 22 in an unusually aggressive public relations push. An official from a different military branch stated that while the landmine incident unfolded, Air Force representatives called reporters directly to ask them to run photo coverage of the event, questioning whether lower-ranking personnel would act with such boldness without high-level backing.
Meanwhile, newly appointed Defense Minister Kang Shin-chul repeatedly emphasized the concept of a "warrior community" during his inauguration ceremony held on the same day prior to the KF-21 event.
A military official noted that it was difficult to understand how Gen. Son could engage in such celebratory behavior hours after listening to the incoming minister’s calls for a warrior community. Footage of the event showed Gen. Son flashing double thumbs-up gestures while 16th Fighter Wing Commander Lee Won-hee stood to his right with his mouth tightly pressed together.
Did You Know? The KF-21 aircraft featured in the Feb. 22 event at Yecheon Air Base had previously completed its initial mass-production rollout ceremony in March under the supervision of President Lee Jae-myung, though the recent ceremony marked merely a handover from the developer rather than full operational deployment.
Status of the KF-21 and Official Air Force Explanations
The Feb. 22 ceremony marked a formal handover of the KF-21 from its development contractor rather than “jeonryeokhwa,” the formal designation meaning the aircraft is ready for actual combat deployment. At present, the KF-21 lacks surface-to-air attack capabilities, and domestic development of its air-to-air weaponry has faced delays, adding to criticisms that the grand promotional rollout was poorly timed.
Defending the event, the Air Force explained that the ceremony commemorated the historic and meaningful moment of the KF-21 being introduced to the Air Force for the first time, 10 years and nine months after system development began. The service added that the event aimed to convey encouragement to the pilots and initial operational personnel who successfully completed the first-unit delivery flight.

How did the Air Force defend the promotional event?
The Air Force stated that the ceremony marked a historic and meaningful milestone 10 years and nine months after system development began, intended to encourage the pilots and operational personnel who completed the delivery flight.
How did newly appointed Defense Minister Kang Shin-chul respond to the security situation?
How is the operational status of the KF-21 described?
The Feb. 22 event was an acceptance handover from the manufacturing contractor rather than full combat operational deployment, and the aircraft currently lacks surface-to-air attack capabilities while domestic air-to-air weapon development is delayed.
How do military observers view the public relations handling of the handover?
Critics within military circles argued that the high-level celebratory display and aggressive media outreach by Air Force personnel disregarded the severe security situation and contrasted sharply with the defense minister’s field actions.
How have defense authorities characterized the timing of the aircraft’s introduction?
Defense authorities have emphasized the technological achievement of completing the 10-year and nine-month system development phase, while acknowledging the ongoing developmental path for the aircraft’s full weapon systems.
What specific gestures were captured in the event video?
The video showed Gen. Son displaying repeated broad smiles, baring his teeth, clapping, and giving multiple thumbs-up gestures, contrasted with 16th Fighter Wing Commander Lee Won-hee standing nearby with a tight expression.
Where did the handover ceremony take place?
The ceremony took place at Yecheon Air Base, home to the Air Force’s 16th Fighter Wing.
How are weapon system developments affecting the aircraft’s current role?
Because the KF-21 currently lacks surface-to-air attack capabilities and domestic air-to-air weapon developments are delayed, the aircraft remains in an initial operational introduction phase rather than active combat service.
What broader implications does this incident carry for the military?
The event underscores the delicate balance defense leaders must maintain between publicizing domestic defense manufacturing milestones and managing troop morale during active border provocations and personnel casualties.
What role does the contractor play in the KF-21 program?
The development contractor manufactures and hands over the aircraft to the Air Force, a process distinct from subsequent operational testing and combat readiness deployment.
How did the Ministry of National Defense coordinate its messaging?
While Defense Minister Kang focused on the warrior community and visited injured soldiers, the Air Force pursued independent media outreach for the KF-21 arrival, revealing divergent communication priorities within the defense establishment.
What specific reaction did the Air Force receive from other branches?
An official from another military branch criticized the aggressive PR push by Air Force personnel to secure photo coverage for the handover while troops were recovering from a landmine explosion.
How does the 10-year and nine-month timeline impact the program?
The extended development period forms the core rationale used by the Air Force to justify the significance of the initial aircraft delivery to flight personnel.
What measures are being taken to address troop morale?
Minister Kang’s direct hospital and unit visits serve as primary administrative efforts to reinforce solidarity with front-line personnel following the border security incidents.
