In response to Japan’s video about the claimed use of a fire control radar against a patrol plane, the ROK Ministry Defense has now released their own video disputing the claims:
The first criticism in the video is that the Japanese aircraft flew at a low and threatening altitude. Here is a screen capture from the ROK perspective of the patrol plane. Does this look like a threatening aircraft?:

The next claim is that Japan is wrong about being in compliance with international law. The ROK video shows that the altitude and distance level the Japanese aircraft maintained was applicable only to civil aircraft according to international law:

This actually discredits Korea’s criticism because then the Japanese patrol aircraft could then fly at whatever altitude it wanted if there is no international standard military aircraft are held to. If there was a military standard between the ROK and Japan I would think they would have included it in the video.
The next claim in the video is that the Korean ship did not use its fire control radar against the Japanese plane. The video says the ship only had its search radar on. To counter the Japanese claim of the use of a fire control radar the video focuses on the fact that no guns from the ship were pointed at the aircraft. This is a completely separate issue that the Japanese side has never claimed. The issue was the use of the fire control radar.
The video also asks that if the fire control radar was used why didn’t the plane use emergency measures to escape. Watching the Japanese video it is clear the crew knew no weapons were pointed at them and thus likely did not feel threatened by the Korean ship.
The next claim is that the Japanese radio communications were unclear. The video had just one short snippet of audio which was unclear. However, there was much more broadcasts by the Japanese plane. I can understand though how trying to understand English spoken with a Japanese accident over a radio could be difficult for the crew on the ROK ship to understand.
Regardless the whole radio issue is really not important compared to the fire control radar issue. The ROK video concludes demanding that the Japanese release their radar data. The technology that nation’s use to collect radar frequency data is sensitive information that I would be surprised is released. However supposedly the Japanese are now considering it:
The South Korean video is “awful,” a senior Defense Ministry official said, adding, “We have to keep rebutting.”
Japan Times
The official noted that the South Korean video did not include radio messages sent by the Japanese patrol plane to the South Korean destroyer, which had been on the Japanese video.
Depending on the responses of South Korea, Tokyo is considering releasing radar wavelength data, usually a military secret, as additional evidence for its claim, sources familiar with the situation said.
Frustration is growing among an increasing number of Japanese government officials at South Korean President Moon Jae-in’s failure to act to resolve tensions over the incident.
Overall in my opinion the ROK video is not convincing, but will likely serve well for the domestic audience in Korea. Does anyone else have any other opinions on the ROK video?
Finally what is really amazing about this whole issue is that between most other countries this would likely be resolved internally between defense ministries instead of being fought over on Youtube. However, as we have seen with so many issues between ROK and Japan domestic politics get involved. As I have said repeatedly the Chinese and the North Koreans are loving this.
