200 meters below the surface of the rolling sea, the light has become very faint, and the blue-green light that is constantly sparkling and swaying is above, and the bottomless darkness is below, and it is quiet here.

In the midst of this silence, a huge oval artificial steel with a total length of 170 meters and a width of 13 meters quietly moved forward, this is an Ohio-class nuclear submarine, which was originally cruising in the Pacific Ocean and received an urgent order to enter Chinese waters to find a transmitter, a signal transmitter.

A week ago, several astronomical observatories in the Asia-Pacific region happened to observe a meteorite falling in the waters of the South China Sea, which is an extremely common thing, the earth is hit by various meteorites every day, most of them are directly burned by the atmosphere, and it is not surprising that occasionally one or two fall to the ground, astronomers can basically determine the composition of the meteor just by relying on the fire light from the meteor that fell to the ground, and in most cases, these are not worth paying attention to.

However, at the same time as the meteorite broke through the atmosphere, the signal receiving instruments of several observatories were affected by disordered clutter at the same time, which made researchers a little confused. It is also a very normal thing for all kinds of clutter to affect the receiver, usually the automatic filter directly filters out all kinds of clutter, but this clutter signal is relatively strong, and it will be repeated in the next few days, although each appearance is messy, but after analysis, there are still several fixed frequencies that will be mixed on the map every time, which attracts the attention of the observatory.

The analysis report finally pointed out that it was very likely that the meteorite that sent this inexplicable signal was the meteorite, and the researchers very much hoped to find the meteorite for research, and even the meteorite itself was a product of an extraterrestrial civilization.

This is a report by the head of an astronomical observatory, in fact, many astronomical researchers and enthusiasts believe in the existence of aliens in their hearts, once they find some so-called clues, they immediately write reports that alien civilizations may be discovered, and do their best to apply for research funds. But that signal was received not only by the Observatory, but also by the Kitty Hawk Aircraft Carrier Strike Group, which was conducting exercises in the Pacific Ocean. The comparison between the two has directly attracted the attention of NASA, which is why it will send the nearest nuclear submarine to secretly dive into the South China Sea.

Let's not talk about whether the meteorite is the signal source or not, anyway, the annual test of China's national defense forces is also a routine task, but this time the task of finding a specific object has been added to the test. But if that meteorite is really a product of an alien civilization, it must find a way to get it in its hands, and God knows if it is taken by the Chinese government, whether it will make a big leap forward in China's science and technology.

Therefore, the Ohio-class nuclear submarine is quietly moving underwater, and at the same time sending F35 fighters to provoke, and the agents arrange surface ships to use international disputes to impact the other party's ** to attract attention, which is just a simple strategy to attack the west. Although the level of China's navy can only be regarded as second-rate in the world, the US government has never underestimated China's coastal defense capabilities. Perhaps the offensive ability is slightly insufficient, but the defense is not compromised in the slightest.

The Ohio-class nuclear submarine is not the most advanced nuclear submarine in the United States, but after the renovation and upgrading, it is at least quietly ranked among the top in the world. Even so, it is not easy to enter China's territorial waters completely undetected, especially since it is necessary to search for things under the sea. However, the U.S. government didn't expect that at this moment, Xia Yu, who had fought with F35 in the sky, could directly determine the location of the signal transmission source, and was worried about how to notify his superiors of his discovery.

Since this signal transmission source can be received by human beings, it will be discovered sooner or later, in this case, it is better to directly let your country get it, not to mention whether it can be deciphered, at least not to let the Americans who often come to stir up the situation pick up the cheap. This was Xia Yu's most direct idea, so after thinking about it for a while, he decided to let the Americans carry a black pot.

Connecting the Liaoning, Xia Yu opened his mouth and said, "Swift calls the Liaoning." ”

"Liaoning received, please speak."

"I found a dark shadow under the water at XX degrees east longitude and XX degrees north latitude, I suspect it is a submarine and ask for confirmation."

After receiving Xia Yu's report, after the Liaoning inquired, there was no submarine of its own people in the area on the mission, and the combat alarm was immediately turned on, and the anti-submarine helicopter and J-15 carrier-based aircraft were urgently lifted into the air, ready to confirm the content of Xia Yu's report.

As a special ship that can pose a huge threat to surface ships, the threat is extremely high when it is not discovered, and it is one of the main functions of submarines to paralyze or sink surface ships, but once discovered, submarines almost lose the ability to threaten the other side, especially when their own position is determined and they are targeted by surface ships and anti-submarine helicopters, and the submarine that is not very fast almost does not even have the ability to escape.

Seeing the anti-submarine ships and anti-submarine helicopters coming, Xia Yu said hello to the other party and began to fly towards the Liaoning. There is no way, the fuel load of the J-31 is on the small side, and afterburner was used several times in the grappling with the F35, and now the fuel is not enough, so it can only land on the aircraft carrier and refuel.

Landing on the aircraft carrier, Xia Yu, who had just walked into the command cabin of the bridge, got the news from Mu Shaoqing that an Ohio-class nuclear submarine was forced to float.

No way. Xia Yu was dumbfounded, he just wanted the surface ship to be closer to the launch source, so that the surface ship would be easier to receive the signal, so as to find the signal transmitter, but he didn't expect that there was really a submarine in that position, which was too much of a coincidence.

"Comrade Xia Yu is a lucky star, he is coming back, and he has made you a great contribution." Successfully forced a U.S. nuclear submarine to float, Mu Shaoqing is so happy, although Xia Yu does not belong to the fighter formation of the aircraft carrier, he is also a member of our Air Force.

Submarines are different from surface ships and airplanes, and the military of any country can sink a submarine that does not belong to it without warning if it finds it within a warning distance.

Submarines, what is a submarine? Just come secretly, don't shoot a gun. A type of Assassin-like ship that hides under the surface of the water and attacks heavy targets. If you don't have any ill will towards me, then why are you sneaking close to me?

Once there is a suspicion that there is a submarine nearby, it is usually to throw down the sonar buoy, when the sonar buoy array is formed, if the submarine is really found in the array, the anti-submarine helicopter will throw down the towed sonar system to keep tracking, in this case, the captain of any submarine knows that his location has been determined, at this time if he does not plan to continue to escape, sorry, you are not negotiable.
