"Report to the General! No, the sonar didn't find any targets, the entire sonar array didn't have any targets, we only had two of our submarines on the bottom of the sea, and they didn't find anything, and the anti-submarine helicopters just reported that they didn't find anything. Pen, fun, pavilion www. biquge。 info" replied loudly to the weapons officer on the side.

"General, are you sure there's a submarine here?" Wei Wuguang's face was full of disbelief, although it is said that China has the most advanced 093A improved submarine, and the decibel level of the submarine has been reduced on a large scale, but in such a dense sonar array, even the latest 093A improved submarine cannot be undetected.

"I'm sure." The admiral said dryly.

"Shall we have those two submarines turn on active sonar to find them?" Wei Wuguang thought about it, and still opened his mouth to suggest.

"No, active sonar, what's the difference between that and our own death, and the detection range of active sonar is limited, and it is impossible to turn on it twenty-four times a day, so don't turn it on yet." The admiral thought for a moment and then spoke.

Active sonar and passive sonar are two concepts, passive sonar is to accept the sound wave noise emitted by the other party, and then judge the position of the other party, but active sonar is like the ultrasonic positioning of bats, emitting active sonar waves by themselves, and then waiting for the sound waves to contact each other, and then reflecting back, and then determining the position of the other party.

And the active sonar will also reveal its position when it is turned on, which is almost telling all the submarines and ships around that I am here, you can attack me, so when the submarine is performing a stealth mission, it will almost not turn on the active sonar, even when it is a sneak attack, if the other party does not find it, it will not take the initiative to turn on the active sonar. Unless the other party has discovered themselves, and they have also discovered the other party, when entering such a state, they will turn on the active sonar to increase the hit rate of the torpedo.

But even in this case, whether to turn on the active sonar or not depends on the situation, unless you take a detour behind the opponent's butt, otherwise, when you turn on the active sonar, you are also revealing your position.

The duel of the submarine is almost the lives of more than a hundred officials on the entire submarine are bound together, and once hit, there is almost no possibility of survival in the deep sea.

The time was approaching minute by minute, and when there was less than a minute before the appointed time, suddenly the sonar officer in the weapons command room shouted loudly: "Report a discovery!" However, the voiceprint signature is very vague, it should be a submarine, the location cannot be determined, and the sound is too quiet. ”

Everyone fell silent, waiting for the sonar man's confirmation, and after more than ten seconds, the sonar man suddenly shouted loudly: "The target has been found, the distance is ...... Uh, less than ...... Less than 100 meters...... Target...... Target sea surface. ”

The more he talked about this sonar, the more he stammered, and he finally understood why he found out, because it must have been captured by the sonar when the other party's submarine rushed out of the sea, otherwise, he would not have been able to find the other party at all, and when he first found out, it was the huge sound caused by the air bubbles caused by the other party's rapid ascent.

"Let's go up and have a look." Admiral Tian Rongguang finally stood up and said with bright eyes.

"Really." Wei Wuguang was a little dumbfounded, he didn't expect that there was really a submarine around here, and at this moment, on another ship, because Liu Jianguo and the others had to hide Liu Fei, they had been waiting on the deck for a long time, until the sea area less than 100 meters away suddenly appeared on the top of the violent white waves, under the light of the helicopter, a black behemoth rushed out of the sea from the bottom of the sea, and Liu Jianguo and the others got a belated report in their headphones.

When they saw this behemoth rushing out of the sea, everyone was completely shocked, especially the naval personnel who carried out relevant anti-submarine missions on the two ships, and the pilots in the anti-submarine helicopters in the sky, they were the most shocked! Because they've just been searching for it, but they haven't found any submarines! And now the submarine has rushed to the surface from the bottom of the sea alive!

Tian Rongguang and Wei Wuguang, who were on the other ship next to them, also stepped onto the deck, and when they saw the behemoth with their own eyes, the two of them were also shocked. Because just now they knew that the two 054D missile destroyers were dragging and dragging sonar arrays all the way, but they didn't find each other.

And now that the other party has appeared in front of him, if this is hostile...... The other party's two torpedoes can directly send them to the bottom of the sea to feed the fish, thinking of this, Wei Wuguang broke out in a cold sweat, but now it is obvious that this submarine should be his own submarine, thinking of General Tian's expression just now, this submarine should not be a new type of submarine newly tested in China! This...... The performance is horrible! A submarine, it can be said that its level of silence is the most critical place for the entire submarine! Nothing else matters!

As long as the mute level is low enough, then it has enough combat power! And now this combat power has been demonstrated, and it is simply unimaginable that it will not be detected directly under the two towed sonar arrays, as long as there are two torpedoes, they can go to see the Poseidon.

"Let's go up." Liu Fei didn't know this, and in order to avoid some things, Liu Fei didn't communicate with Fluttershy, but although Liu Fei didn't know the truth of the matter, he could feel that Liu Jianguo's expressions were a little strange. Regarding Liu Fei's opinion, Liu Jianguo naturally had no opinion, and soon all the people who got on the boat got on the two small boats and sailed directly to the submarine.

When he arrived near the submarine, Liu Jianguo saw that there were already four soldiers wearing camouflage uniforms standing there on the submarine, but these camouflage uniforms had no military rank on them, nothing on them, and it was unknown whether this was a temporary replacement or something else. But at a glance, Liu Jianguo knew that these soldiers were all elite, and it seemed that their guesses were correct, and the other party really had its own armed forces, although these armed forces may not be very many, but they are definitely elite.

There were nearly twenty people in total, and soon all of them entered the submarine, and as soon as they entered, Liu Jianguo's first feeling was that they were big, that is, big! Although Liu Jianguo has not been to other submarines a few times, it is obviously impossible for other submarines to have such space, and unlike those submarines in China, many of the equipment in the whole submarine are quite advanced, and they are very advanced at a glance. And some touch screens can be seen in various parts of the submarine, which should be able to be used to query something.

"Mr. Liu!" After Liu Fei and the others came down, a T1000 robot who had been waiting on the side quickly walked over and gave Liu Fei a military salute. Liu Fei also nodded and replied, and then said, "Tell them about the performance of this submarine."

"Mr. Liu, just now I saw that the shape of this submarine is a little weird, and I want to ask, is this submarine different from the traditional propulsion method? What is the ferrofluid propulsion employed?" An old scientist pushed the glasses on his nose and asked directly.

"Yes, this submarine uses ferrofluid recommendations, so it can reach a maximum speed of more than 55 knots. Of course, if you want to run faster, you can do it, but in that case, it will cause some damage to the equipment. Liu Fei said with a smile.

What does the speed of 55 knots mean, all the people around who know about submarines are in an uproar, especially for a submarine, the engagement between submarines and submarines is more of an engagement between torpedoes, but the maximum speed of many torpedoes is only this speed, and now the speed of this submarine can reach such a speed. And it could be even faster!

Then Liu Fei didn't participate, all the places in the whole submarine were all visited, along the way, Liu Fei knew, the dozen or so old men were really engaged in research, and when they saw something, they were like filial sons, so they pounced directly and began to study themselves, and if there was a problem, they would directly catch it and ask, which was also fortunate that it was this noisy man who knew a little bit about everything, otherwise, let Liu Fei probably have a big head.

For this provocation scientist, they are concerned about the advanced technology of this submarine, but for other admirals, they are concerned about combat effectiveness, from beginning to end they can see that there are not many officers and soldiers in this submarine, but it has a lot of space, under the control of 110 submarine officers and men, it can also accommodate up to 96 fully armed special soldiers for dozens of days of sneaking, and then send the other party to the target location to carry out the mission.

When the final visit to the command room, the unique command room and the quite powerful communication capabilities, as well as the unique underwater holographic detection radar, simply looked at these people stunned, when the visit was completed, even people like Liu Jianguo were a little shocked, many of these technologies can be used beyond the times, especially the holographic simulation radar, although it can only establish a state around a radius of thirty kilometers, but this is also quite powerful.

This can almost simulate a battlefield in three dimensions, how much will this help the state of war, Liu Jianguo certainly understands, this can be intuitively reflected in many operations of the commander. Because such a stereoscopic simulated position allows the commander to immediately know where all the ships, aircraft, and so on of his fleet are located.

"Can this operational radar and holographic simulation technology be built on a large ship on the surface, and how much does it cost? And what technology?" Liu Jianguo asked Liu Fei very dryly.

"Of course, it can be built on a large ship on the water, and if it is a modified command ship, its maximum range can build a holographic detection map with a radius of 300 kilometers, and a complete three-dimensional space of land, sea and air." Liu Fei thought about it, in fact, this technology is not very difficult, but some of the materials in it are not found on the earth at all, and this requires some materials in space, so if you want to build such a radar, Liu Fei does not want to provide it for a while.
