The 10,000-ton Daqi 055 is the largest, strongest and most advanced destroyer of our navy, and also one of the most advanced destroyers in the world. However, although the 055 drive is very strong, it is now a peaceful era after all, so there are not many opportunities for 055 to "show their talents". Compared with the powerful 055, another ship of our Navy is likely to give the US military a "headache" in peacetime, that is, the 815/815A electronic reconnaissance ship of our Navy.
There has been a saying on the Internet, "If you are not afraid of 055, you are afraid of 815." The reason is that although this kind of electronic reconnaissance ship itself has almost no combat effectiveness, it can also cause great trouble to the US military by virtue of its powerful shipboard electronic equipment, especially since it will go to the exercise area of the US Navy and even the US Navy aircraft carrier from time to time and swagger through, but the US military has nothing to do about it. After all, on the high seas, your US military can exercise, and of course our electronic reconnaissance ships can pass by. So, what is the power of this electronic reconnaissance ship that can give the US Navy, which claims to be the best in the world, a headache?
First of all, this type of ship has powerful shipboard electronic equipment, including extremely powerful large-scale over-the-horizon radar, electronic arrays, and listening equipment, as long as this type of ship passes through the activity area of the US military, then every move of the US military can be "fully seen" by the ship, and not only that, because the US warships will produce a large number of electronic signals when they are active, these electronic signals will naturally be obtained by electronic reconnaissance, so after a long time, a lot of technical data of the US military will be leaked in large quantities, and this is the most uncomfortable for the US military. For example, if the U.S. military launches missiles and other simulated strikes during the exercise, then the time, trajectory, range, and landing point of the missile can be calculated, and this information is obviously data that the U.S. military is unwilling to make public.
Second, the electronic reconnaissance ship also has an important function, that is, it serves as a relay guidance ship for missile strikes, that is, it plays the role of a sea guidance ship. Once an electronic reconnaissance ship appears in the relevant sea area, then theoretically the ship will have the ability to collect and aggregate the information of the ships in the relevant sea area, and if this information is provided to the missile forces, then no matter how powerful the fleet on the other side is, it is theoretically possible to be fully covered by missiles in a short period of time. Therefore, once the seemingly unarmed and harmless 815 appears near the US aircraft carrier, it actually means that the aircraft carrier may actually be "terminated".
In the face of this kind of electronic reconnaissance ship, the US military can actually say that there is nothing to do, after all, anyone can go on the high seas. In fact, the only way for the US military to deal with it is to also use electronic warfare to develop electromagnetic over 815 in order to seize regional electromagnetic supremacy. However, due to power reasons, the electronic warfare capability of a large number of EA-18 electronic warfare fighters carried by US aircraft carriers cannot be compared with the electronic warfare capabilities of electronic reconnaissance ships, after all, the radar power that an aircraft can carry is much less than that of an electronic reconnaissance ship of several thousand tons. However, the United States is inferior to our military in the field of ships of the same type, so in the face of the "normal navigation" of our army's Type 815 electronic reconnaissance ship, the US military has no choice but to stare dryly.
Nowadays, with the progress of technology, the number of our army's 815/815A electronic reconnaissance ships has become more and more; in addition to countering the US aircraft carriers that dare to approach the coast of the western Pacific, this type of ship has also "taken the initiative" on many occasions and has gone to the vicinity of the Ryukyu Islands, the Japanese archipelago, and Australia.
