This video features the KF-21 test pilot himself explaining the behind-the-scenes story of the aircraft's development.
What I’ve recently learned are the subtle differences between the KF-21 prototype and the production models.
출장땜에 사천 근처를 들릴일이 있었던데다가 마침 일정이 일찍 끝났음(직함은 연구원인데 전국방방곡곡을 다니는 듯. 2년전에 뽑은차가 벌써 5만 넘었네. 후...) 근데 95년 에어쇼 부터 꾸준히 본터라 이제 가봤

This is the tail boom of Prototype No. 3.
This is the tail boom of the first production model.
According to the test pilot's explanation, the production model features a thicker tailboom design to reduce airframe vibration.
In response to feedback that the aircraft was somewhat sensitive along the roll axis during flight, the control stick design was modified and the OFP was improved.
According to rumors circulating online, the first production model will be delivered to the Air Force on the 17th of next month.
The first Meteor launch from the KF-21 Block II prototype is scheduled for this month, August. The Block II prototype is equipped with not only the EO TGP but also a 480-gallon external fuel tank as standard. This test is intended to verify whether the Meteor can be launched safely with this configuration.
