January 21, 2019 (Google Translation) – Regarding the case of firearm control radar irradiated to the P-1 patrol aircraft (Atsugi) belonging to the Maritime Self-Defense Force 4th Aviation Group from the Korean navy destroyer occurred on Thursday, 20 December last year, the objective fact that the Japanese side has We decided to publish the final opinion of the Ministry of Defense that we compiled and the sounds detected by the Aircraft at the occurrence of this case.
As for the Ministry of Defense, we strongly protest the fire control radar irradiation to the maritime P – 1 patrol aircraft by the destroyer of South Korea again strongly, and we strongly urge the Korean side to recognize this fact and thoroughly prevent recurrence . Furthermore, even if we continue discussing the working group further, we can not believe that it will lead to the investigation of the truth, so we will conclude that it is no longer possible to continue discussion with the Korean side on this case.
We hope that this announcement will lead to the prevention of recurrence of similar cases and will continue to strive for continued defense cooperation between Japan, Korea, Japan, the US and Korea.
The Ministry of Defense has been working closely with the defense authorities of Japan and Korea so far and we have repeated serious discussions between Japan and Korea on the issues surrounding fire control radar irradiation at this time. However, it is regrettable that we have not resolved the gap of recognition to the major issues including the presence or absence of irradiation until today.
For the Ministry of Defense, we decided to compile and publicize the objective facts that the Japanese side possesses from the perspective of taking the matter seriously and strongly seeking to prevent reoccurrence.
We hope that this announcement will lead to future recurrence of similar cases.
Since Japan is surrounded by a vast waters, the Ministry of Defense responds to various situations in a timely and appropriate manner, and in order to securely protect the life, body, property, territory, territorial waters and airspace of the people, in the surrounding waters of Japan We are monitoring warnings and gathering information for a wide range of foreign warships, etc, that are active from the beginning.
As announced in the movie on December 28 last year, as part of the general watch surveillance and information gathering around 3 pm on the 20th of the same month, the ocean P-1 patrol aircraft was sent to Japan’s exclusive economic zone (EEZ ) During the flight, confirmed the Korean Destroyer and the Korea Security Rescue Ship, and suddenly received the irradiation of the fire control radar from the destroyer, the naval P-1 patrol The machine immediately took actions to ensure safety.
Irradiation of fire control radar is an action to be carried out prior to the use of firearms and irradiation without a reasonable reason for other aircraft of a different country is a very dangerous act which can lead to unforeseen circumstances.
In the CUES (Code for Unplanned Encounters at Sea) adopted by the Navy, etc. of 21 countries including Japan and South Korea etc. in 2014, these actions are considered as simulation of attacks , It is stipulated as one of the actions the commander should avoid.
In response to the occurrence of such serious cases, the Ministry of Defense strongly protested against the Korean side and requested the prevention of recurrence, but the Korean side not only denied this fact but also informed the Ministry of Defense ” Distorted “and” responding to threats flying in low altitude “apologies for seeking apologies from the beginning.
As a result of careful and detailed analysis of the frequency, intensity, received waveform etc. of the radar wave irradiated on the maritime P-1 patrol aircraft by the Ministry of Defense, a military P-1 patrol aircraft carried out photographing etc. We confirmed that the radar wave from the Korean destroyer ‘s fire control radar (STIR – 180) was irradiated several times continuously for a certain period of time. The same radar was not installed in the South Korea security rescue ship located in the vicinity, and the fact of the irradiation from the Korean destroyer was also confirmed from the content of the movie released by the Ministry of Defense on December 28 last year it is clear.
As the Ministry of Defense, as a further basis for the irradiation of the fire control radar, the crew of the maritime P – 1 patrol aircraft took the preservation measures to convert the detection radar wave to sound, which was heard on the plane We decided to make it public on the website of the Ministry of Defense.
In general, the fire control radar is used to continuously hit a target with a radar wave in order to hit a missile or shell, accurately grasp the position, speed, etc., There is a clear difference between the data such as waveform and search radar for taking out and searching for and discovering the surrounding target. Therefore, by analyzing the radar wave, it is possible to specify the type and source of transmission, and the radar wave irradiated to the P-1 patrol aircraft this time showed the characteristic characteristic of the fire control radar .
It is clear from the analysis results of the Ministry of Defense that this radar wave was issued by the marine destroyer’s fire control radar that the photo shooter carried out the photo shoot, etc., but objectively and neutrally In order to recognize the facts, based on mutualism, we compare the information of the radar wave detected by Japan with the detailed performance information of the firearm control radar equipped by the Korean destroyer and make a comprehensive judgment It is essential to do.
Based on these facts, the Ministry of Defense conducted factual consultations on January 14 this year based on reciprocity principles, such as finding radar waves detected as the basis of analysis results and data converting radar waves into sound We suggested that the evidence contributing to the Korean destroyer and the performance of the firearm control radar of the Korean destroyer and the usage record of the radar were checked by collaborating with each other after thoroughly managing the information, but it was not accepted . Furthermore, we also propose the same purpose at the working-level consultation on December 27 last year. In the working-party talks on January 14 this year, as one of the evidence that contributes to the fact confirmation, bringing the radar waves that were detected into sounds and bringing the data and asking the Korean side to listen on the spot Although it proposed, the Korean side also refused the proposal.
Korean Ministry of Defense spokesperson condemned the Ministry of Defense’s proposal using diplomatically unusual terms as “rude” on the 15th next day, and informed the details of working-level consultations on 14th of the same month Contrary to the agreement, we unilaterally clarify the contents different from the facts. Such a speech by the spokesman is extremely regrettable because it will hurt the trust relationship of both parties and interferes with frank opinion exchange, and the Ministry of Defense will not repeat such behavior on the 16th of the same month I have strongly asked, but from the Korean side, no sincere answer has been obtained.
Considering that the series of Korean side as described above and the Korean side assertions so far are not consistent and lack credibility, the Korean side repeatedly makes allegations completely different from facts I can not but conclude.
Under such circumstances, it is difficult to objectively and neutrally make fact finding based on reciprocity, so continuing further negotiation of workers can not be considered to contribute to the investigation of the truth. As for the Ministry of Defense, we strongly protest the fire control radar irradiation to the maritime P – 1 patrol aircraft by the destroyer of South Korea again strongly, and we strongly urge the Korean side to recognize this fact and thoroughly prevent recurrence .
On the South Korean side, the maritime P – 1 patrol aircraft insisted that the “destroyed threat at low altitude” at a close distance to the Korean destroyer engaged in the “humanitarian rescue operation”, requesting an apology I will.
Although there is no international law to directly determine the minimum safety altitude of military aircraft, the maritime P – 1 patrol aircraft is flying according to the Japanese aeronautical law in accordance with the International Civil Aviation Convention in order to ensure safety, and to the Korean destroyer I have not done any threatening flights. We are also aware that the normal operations of the US military and NATO are conducted in accordance with similar standards.
In fact, as is clear from the contents of the movie released by the Ministry of Defense on December 28, 2008 and the navigation map of the maritime P – 1 patrol aircraft, this maritime P – 1 patrol aircraft is the most Even when approaching, we have secured sufficient altitude (about 150 m) and distance (about 500 m), and we are not doing any flight that interferes with the destroyer’s activities. Since there was no radio call from the Korean destroyer, the Ocean P-1 patrol aircraft could not recognize that the Korean side is doing rescue operations.
There is no basis to support the Korean side’s claim in the image of about 10 seconds that it seems that the marine P-1 patrol aircraft was taken from the security boat’s small boat announced by the South Korean side, There is no indication of any objective basis to support the Korean side’s claim that the aircraft “flew threatened with low altitude”.
Until now, at the Maritime Self-Defense Force, when checking not only South Korea but also foreign warships etc. during warning surveillance and information gathering, we do the same flight as this time and take pictures. After April last year, we shot three shots (April 27, April 28, August 23, 2011) to the Korean destroyer (“Kwanget de Wang”) which took a picture this time In doing so, we have never raised a problem from the Korean side.
Although the Ministry of Defense requested the presentation of further objective grounds at the working-level consultation, the Korean side did not show such things, but conversely, “If the threat is felt as a threat, It is a threat, “such as repetitive answers lacking objectivity at all.
Because of this, in the Ministry of Defense, the argument of the Korean side lacks persuasive power not based on objective grounds, it is not to say that it is to dilute important issues concerning irradiation of fire control raider I do not believe.
Generally, when a crew member of a ship feels danger, we will make a radio call, but the Korean destroyer calls for a danger to the Aircraft while questioning the flight of the maritime P – 1 patrol aircraft I have not done anything at all.
In addition, the ocean P-1 patrol aircraft made a call using the international VHF (156.8 MHz) and emergency frequencies (121.5 MHz and 243 MHz) after receiving the irradiation of the fire control radar, There was no response from the ship.
About this problem, the Korean side explained that the communication environment of the site was bad, hardly heard the call from the Aircraft, and he did not respond because he heard “KOREA COAST”. It also explains that one of the three frequencies was not setting communication equipment in a state where it could be heard.
However, the scene of the site on the day was fine weather and few clouds, the communication environment was very good. In addition, the Ocean P-1 patrol aircraft used Saitama prefecture (Saitama Prefecture) using the same communication equipment (previously confirmed that the communication equipment was operating normally before flight, during flight and after flight) In addition to having been communicating with the land stations of the Air Self Defense Force which had been flying at a distance of about 240 km from the site, I also confirmed that he was listening to the aircraft’s call for this destroyer.
Despite this good communication environment, it is not normally thought that communication could not be clearly received, and in the movie actually released by the South Korean side, it was confirmed that the naval P- 1 It is possible to clearly hear the content of the call of the patrol aircraft (“KOREAN SOUTH NAVAL SHIP, HULL NUMBER 971, THIS IS JAPAN NAVY.”). Regarding this point, the Korean side confirmed repeatedly the call from the maritime P – 1 patrol aircraft at the working – party talks on January 14 this year and confirmed later that it was a mistake in listening to the communication watch I explained it for the first time. Until now, the Korean side explained only that he did not respond because he heard “KOREA COAST” at a press conference and other places, and did not reveal such facts.
As for the Ministry of Defense, in order to prevent such problems from occurring again in the future, we will ask the Korean side to conduct appropriate communication with the SDF, etc., improve the standby state of communication, educate / train communication personnel etc , We will seek measures to improve communication at the site between the defense authorities of Japan and Korea.
For the above reasons, the Ministry of Defense strongly protests against the fire control radar irradiation to the maritime P – 1 patrol aircraft by the destroyer of South Korea again and acknowledges this fact to the Korean side to thoroughly prevent recurrence I strongly demand that.
Meanwhile, since there is no attitude to respond to objective and neutral fact finding based on reciprocity on the Korean side, even if we continue negotiations with workers on the presence or absence of radar irradiation, we have reached investigation of the truth It is considered that there is no longer any difficulty in continuing consultations on this case with the South.
On that basis, defense cooperation between Japan, Korea, Japan, the US and Korea is extremely important to maintain a stable security environment in the East Asia region, including North Korea’s nuclear and missile issues, and it is essential There is no change in recognition. We hope that this announcement will lead to the prevention of recurrence of similar cases and will continue to strive for continued defense cooperation between Japan, Korea, Japan, the US and Korea.
