Less 300 kilometers from Tokyo!Why can Chinese reconnaissance vessels detour the Japanese islands repeatedly?

[Military Bills Plane] Author: Lele

On June 26, the Ministry of Defense of Japan stated that the Chinese Navy's "794" electronic investigating ship passed from the Izou Islands on the southern Japan Islands in the early morning of the day. This is the first time that my country's naval military ships have taken the Royal Tibetan Island route near Tokyo. It is only less than 300 kilometers away from Tokyo recently, which can be imagined on the impact on Japan. In fact, this is not an electronic reconnaissance ship equipped with my country's navy equipment. The first time the first record is close to the Japanese islands. On May 20th, the "795" electronic investigation ship also attracted great attention from the Japanese media because of only 90 kilometers from Kyushu Island, Japan. So the question is, why did the 815 series electronic investigation ships equipped by my country's navy have repeatedly broken the previous records in the near future?

On September 8, 2017, the seventh domestic 815A electronic investigation ship was launched. This is the sixth warship that has been launched since 2014. It indicates that its construction technology has made a comprehensive breakthrough. attitude. In fact, the Navy has been equipped with eight 6,000 -ton 815A electronic investigating ships, which are affiliated with three fleets. The most important task is to monitor the surface ships of the waters near the Japanese islands and the Western Pacific waters. And the radar and communication equipment set on the surrounding islands. This time the "794" ship departed from the Bohai Sea and crossed the Hippo Strait, the Kyojin Strait, and the south of the Royal Tibetan island all the way. In fact, most of the islands of Japan have been sailing. Complete the feat of a single ship around the Japanese islands with auxiliary warships.

In addition to the propaganda significance brought about by itself, the substantial military significance behind it is actually not to be underestimated. Specifically, the 815A electronic reconnaissance vessels are in the front of the hull, with a mast of nearly 50 meters high, with a variety of antennas of different uses. It is generally believed that this is the core equipment area of ​​815A, which can monitor the radio of the vast majority of common frequency bands. Especially when facing large radar and communication facilities set on the mainland or islands, it can collect and analyze the electromagnetic information of these electronic devices more accurately and sensitively, and provide basic data for the navy to develop the corresponding electronic interference devices. However, the 815A electronic reconnaissance ship monitoring the various types of equipment of radio is limited after all, and the distance between the function is also greatly affected. In order to ensure the effect, it requires the target equipment, so it will have repeatedly broken the record of the Japanese islands in the near future.

And the Navy 815A is not just around the Japanese islands. On May 12 this year, the Australian military released news that the Chinese Navy's "792" electronic reconnaissance ship was close to the Australian military communication station twice in the previous week. It is only 50 nautical miles away from the coast, setting up the two records close to Australia and the farthest sailing in the southwest. As for the purpose of the "792" ship, it is naturally almost the same as the "794" ship's bypass the "794" ship above. Therefore, when domestic public opinion has repeatedly focused on investigative vessels and planes in the United States, Japan, Australia and other countries, and rarely realized that the domestic 815A series advanced electronic investigation ships have been realized when they are active.

More importantly, the 815A electronic investigating ship, as a medium -sized ship with self -reliance in about 50 days, can hardly go to the surrounding waters to observe the military exercises of the United States and Japan and Australia at close range. Among them, the more well -known ones include the "853" ship to the Hawaii waters in the north in 2014 to monitor the US Navy's "Pacific Pacific" military exercise in 2014. This is the first time that the 815A series has completed such a long distance. The "794" ship completed the recent investigation operation of similar recently detouring Japan Islands, which was also a sensation at the time. Even in April of this year, the "794" ship also entered the Sea of ​​Japan, approaching the Japanese Sea from the nearby seas of the nearby waters and the US Navy's "Lincoln" aircraft carrier. After the performance of the Navy 815A series of electronic reconnaissance vessels, the excellent characteristics of the excellent characteristics of the excellent characteristics are evident.

In addition, in addition to the towering masts, 815A is also equipped with three more conspicuous large antenna hoods. Among them, the largest antenna cover is located in the middle of the hull. Missile test. When the Navy built a more basic 815 electronic investigation ship more than 20 years ago, the ship has not set up a large antenna cover that protects and improves accuracy. The measurement and control antenna. However, the Yuanwang series is to ensure the smooth launch of domestic ballistic missiles and carrier rockets, while 815/815A is to monitor the movement of ballistic missiles in other countries.

In 2017, the Navy's "852" ship went to the sea near the sea of ​​Alaska. At that time, this very impactful action caused global attention. The American media even the action of the "852" ship with the Soviet Navy during the Cold War to maintain a close contact with the US Navy's aircraft carrier formation, monitor the launch of American ballistic missile launch Link with interception tests. Although the US media reported at the time, it was obviously exaggerated. After all, the Chinese navy started late in this field and could not compare the size of the Soviet Navy during the peak, but the positive attitude of active activities has caused the U.S. Navy to feel the pressure. ▲ The "Ural" nuclear power reconnaissance ship of the Soviet Navy legend

In recent years, the focus of the domestic navy has been concentrated on large and medium -sized destroyers such as 001/002/003 aircraft carriers, 055/052D and other large and medium -sized destroyers. Warships such as 815A have a limited tonnage and belonging to auxiliary ships. However, in fact, such combat nature is not strong, and it will not easily lead to heating up. At the same time, with the advanced electronic equipment equipped, it will have excellent formal reconnaissance characteristics. Whether it is the past or the future, the surrounding countries will not be under the main destroyer of the Navy's main destroyer.
