In the southeast coastal areas of China, in fact, many fishermen make a living by fishing, but some fishermen catch some underwater vehicles, that is, what we call torpedoes and other military weapons. What makes people laugh and cry even more is that Chinese fishermen get high rewards after salvaging torpedoes, which makes the fishermen at the seaside fall into the craze of salvaging underwater vehicles. Once an American submarine was salvaged by fishermen underwater. After seeing the sonar dismantled and towed away, the American warship fled directly.
First, the working principle of underwater vehicles that fishermen in China often salvage.
Anyway, these underwater vehicles that are often salvaged have certain working principles. Taking sonar as an example, sonar could have been placed offshore to explore the corresponding coastline. That is to say, if this kind of thing was placed offshore, we could accurately draw a map of China's coastline, which would cause a crisis to China's national defense security. Take torpedoes for example. In fact, more torpedoes will appear a little farther offshore, but this torpedo must be malicious at first, but it will have advantages and disadvantages if it is finally salvaged by fishermen. The advantage is that this advanced torpedo can be used to develop more advanced weapons, and the disadvantage is that it will pose a threat to the life safety of fishermen.
Second, it is extremely harmful to our country.
Of course, this is very harmful to our country. First, it will directly affect the life, health and safety of fishermen. After all, torpedoes explode when they say they explode. Once they explode, they will not only hurt fishermen, but also have a chain reaction to people around them. Secondly, more submersibles will actually spy on some secrets of our country, which means it may pose a threat to our national defense security. Judging from all kinds of disadvantages, this is really harmful to our country.
