American: Chinese fishermen, I have nothing to do! What mysterious underwater devices have been lo

Chinese fishermen caught torpedoes from the United States, submarines from Australia. The Australian submarine is equipped with advanced filming equipment and intelligence-gathering equipment, and if this device is not discovered, it will steal China's confidential information, so the Chinese fishermen have made a great contribution.

American: Chinese fishermen, I have nothing to do! What "mysterious underwater devices" have been lost by the US Navy? Missiles, torpedoes, underwater gliders, and detectors of various models.

Recently, a Croatian fishing boat recovered an unidentified underwater device in the Adriatic Sea. However, the U.S. Navy quickly retrieved the equipment after hearing the news, leading the outside world to speculate that it was likely to be underwater reconnaissance equipment dropped by the U.S. Navy's survey ship.

Chinese fishermen have caused tens of millions of losses to the United States, and even more disrupted their "spy plan", so they are called "sea nemesis".。Because China's development speed is too fast, the United States and some other countries feel jealous, so they try every means to drop spy equipment into our waters, just to find out more information. Fortunately, there is a group of "Chinese fishermen" along the coast of our country, which not only caused heavy losses to the US military, but also was able to take advantage of the opportunity to make money, which has simply become their second occupation.

First of all, I believe that many people have heard of the phrase "sonar has no copper, fishing is useless", although it is just a paragraph, but it also proves a fact while it is funny. Back then, the U.S. disguised itself as a regular vessel and dropped sonars into our waters in order to gather more information and send it back to the U.S. But what I didn't expect was that thousands of storage buoys were salvaged by Chinese fishermen as soon as they were put into the sea.

During that time, Chinese fishermen regarded it as the main economy, after all, the more you catch, the more rewards, and you can also get a good reputation, which is simply a lot of money. In the face of this situation, the United States can only "eat coptis dumbly, and can't say anything about it", which is why there is this funny joke.

Secondly, in 1978, several fishermen in Hainan Province caught an iron fish in the process of fishing, because the English letters on it could not be read at all, so they directly sent it to the relevant departments for identification by experts. It was later confirmed that it was an American-made torpedo, which was at a very advanced technology in the world at that time. You must know that our country is very backward in this regard, and the torpedoes salvaged by fishermen are like "free tutorials", and many experts in our country have studied and imitated them.

Later, some fishermen salvaged a number of torpedoes one after another, which invisibly promoted China's torpedo technology.

In the end, Chinese fishermen can simply be called "America's nemesis at sea." No matter what the other side throws down, it will be fished out, which can make the United States suffer heavy losses, after all, the ** of a sonar alone will reach 9,000 yuan, and these torpedoes are even more expensive. For Chinese fishermen, as long as you dare to throw me, I dare to fish, and they even dare to use fishing boats to warn those boats that illegally invade our waters, faster than the navy.

Ten years ago, the US military survey ship was dispatched again, sailing to the South China Sea area to carry out activities, Chinese fishermen appeared again, before the US military's sonar buoy was placed, the Chinese fishermen directly salvaged it, the US military almost spoke Chinese, even if it is worthless things, Chinese fishermen will never let go, helplessly, the United States can only watch its equipment being "snatched". Let the money lost by the United States be immeasurable!

The US military's sea nemesis is the "Chinese fishermen", who will always "pick up" all kinds of props that the US military has put in the sea and hand them over to the country, which has caused the United States to lose a lot of money.

They have caused the US military to lose a lot of money, which is still very bad, and they have also disrupted some of the plans of the US military.

The U.S. Navy, which occupies maritime hegemony and terrified many countries, is trapped by the Chinese fishermen, a non-governmental organization. In fact, the entanglement between Chinese fishermen and the U.S. Navy has a long history. In October 1978, when Chinese fishermen went out to sea, they caught the American MK 46 anti-submarine torpedo, which was the most powerful torpedo in the world at that time.

The United States originally wanted to detect the situation in China's coastal waters, but unexpectedly, it was caught by fishermen, and the US Navy suffered heavy losses. Later, the United States said that all kinds of detection and sonar equipment dropped into Chinese waters had been caught by fishermen, but because the United States itself had bad intentions, it could not openly criticize the behavior of Chinese fishermen, so it could only eat Coptis chinensis in a dumb manner. <>

As a matter of fact, the fishermen's behavior of fishing for US equipment on the one hand safeguarded the integrity of China's territorial sea sovereignty and prevented the military situation along China's coastal areas from being spied on by the United States, and on the other hand, the advanced equipment from the United States at that time also promoted the development of China's maritime military industry at a certain level. In order to encourage fishermen to act righteously, China has even set up relevant awards to give high bonuses to fishermen for catching torpedoes and other special equipment.

In 2011, Jiangsu fishermen salvaged an underwater drone from the United States, which uses optical fiber and satellites to transmit information. The robot can lurk underwater like a ghost, detect the coastal area, the military operations of the Chinese Navy, etc. Perhaps to the surprise of the Americans, it was not the Chinese navy that repeatedly broke their defenses, but the Chinese fishermen who made their living from fishing properties along the coast.

At the end of July 2022, fishermen, also located in Jiangsu Province, caught underwater detection devices from abroad while carrying out normal fishing operations. The Chinese side has carefully studied the detection devices caught by the fishermen, which has greatly made up for the gaps in China's relevant fields and promoted the development of the Chinese Navy's surveillance undertaking in a certain respect.

You must know that Chinese fishermen often catch some strange things when they are fishing, and there are many American-made reconnaissance equipment, so there is a saying that the US Navy is afraid of Chinese fishermen, but in fact this is just a joke.

This device is an eavesdropping device and detection device, and can be used to listen to some voice calls around and detect the surrounding terrain.

With the continuous improvement of China's comprehensive national strength, foreign countries have made use of their own scientific and technological advantages to increase the threat to China's maritime security. Some fishermen have salvaged a lot of suspicious equipment in the process of fishing. Fishermen send the caught objects to the relevant departments for research and identificationIt turned out that these unidentified objects belong to surveillance equipment, also known as underwater unmanned underwater vehicles, and their main purpose is to steal military information in China's coastal waters, understand the deployment of the navy in an all-round way, and carry out targeted strikes during special periods.

Development of underwater unmanned underwater vehicles. Early equipment was mainly used for civilian tasks such as shipwrecking, salvage, deep-water exploration, and submarine cable laying. Nowadays, with the rapid development of science and technology, unmanned underwater vehicles have been widely used in underwater battlefields.

The harsh deep-sea environment creates a natural battlefield fog that deters submarines. Unmanned underwater vehicles (UAVs) have demonstrated strong stability, risk tolerance and flexibility, and can dive into the deep sea area to perform various tasks, including underwater topographic exploration and mapping, and can also carry out underwater active attacks during special periods. Because the device does not require logistical support, it can perform tasks alone, and with the increase of volume, its endurance can be greatly improved, so it is favored by many countries.

Submersibles salvaged by fishermen. The submersibles fishermen salvage are relatively small in size, and their power systems mainly use batteries, so the sailing distance is relatively short. Therefore, according to such characteristics, it is very likely that such submarines will come from neighboring countries.

They carry out topographic surveys of China's coastal waters through remotely operated submarines, transmit the data to the server through radio communication technology, and draw a topographic map of the coastal waters. The manufacturing cost of small submersibles is relatively low, and there is no use value.

Protection against unmanned underwater vehicles. Because of the small size of the submersible, it is difficult for sonar systems to detect it. To protect port terminals and military facilities, electromagnetic interference equipment can be laid underwater.

Obstructs the transmission of signals from the submersible to the receiver. In this way, such incidents can be greatly prevented.

Recently, the U.S. Navy can be said to have been embarrassed again, Yemen's Houthi frogmen "captured" an unmanned submersible in the sea area, for this unidentified object, the United States declared after a few days of silence that the unmanned submersible is the equipment of the U.S. Navy, its main role is responsible for the detection of the marine environment, of course, the specific role is only known to the United States itself. However, even if the U.S. Navy does not express its opinion on this equipment, anyone with a discerning eye knows that this ** is produced by the United States, just because the English letters on its shell have indicated its origin.

You can see that there are such letters on this salvaged unmanned submersible - hydroid, hydroid company is currently the world's top underwater robot manufacturing company, this company was established in 2001 in the United States. At present, the research and development of unmanned deep diving robots can reach 6000 meters underwater for scientific research work, although the establishment is only a short 17 years, but the hydrogen company has more than 400 cableless underwater robot products, has a huge influence at home and abroad, the underwater robot it manufactures is quite complete, it is not an exaggeration to call it "underwater spy".

Judging from the published information, the product salvaged by Yemeni militants this time should be the new Remus 600 cableless underwater robot, which was invested and developed by the US Naval Research Office. As can be seen from its model, this robot can work at a depth of 600 meters, according to the data released by the U.S. Navy, although the robot is designed to work at a depth of 600 meters, it can enter 1500 underwater after simple modification.

Moreover, in order to meet the combat needs of the U.S. Navy, this underwater robot is equipped with a high-capacity battery, which can ensure that it works underwater for 24 hours on a single charge, and the charging process is as simple as our common electric vehicles, and it can be charged without disassembling the battery structure. The robot is equipped with state-of-the-art detection equipment, such as underwater positioning and navigation systems, inertial measurement units, Doppler velocity logging, etc., which can transmit real-time data with operators. Even through radio and communication operators, such a high-end underwater robot can be said to represent the world's top underwater robot technology.

The "capture" of this underwater robot is undoubtedly quite tricky for the US Navy, and this matter also reminds me of some of the previous feats of Chinese fishermen, the United States continues to drop similar underwater robots in the waters near China, but this tactic has been defeated by Chinese fishermen, and a large number of advanced US military robots have been salvaged by Chinese fishermen. And this time such an incident happened again in Yemen, where the U.S. Navy escaped from the Chinese fishermen in the Gulf of Aden, but not the frogmen.
