Technological progress is the first element in improving the performance of weapons and equipment. But the technology is involved... thugs, and in the end it becomes minimal.

submarine field. Technological progress has long passed the "tipping point"

According to the more accepted version. The comprehensive promotion and application of "all-electric propulsion technology" is the critical point to improve the silent performance of submarines. Since then, the impact of technological progress has increasingly been that small decibel noise requires a higher price. It is precisely for this reason that as early as around the year of the craftsman, it was proposed that if we do not change the way of thinking and still blindly pursue the best mute effect, the mute technology of submarines will reach an extreme value in the old years, and it will be difficult to improve again. The advent of "ferrohydrodynamic propulsion technology". Advance the fulfillment of this prophecy. Initially, the Republic and the United States were hesitant about "magnetohydrodynamic propulsion technology", not because the two countries did not have sufficient technical reserves, but because the progress brought by this technology to the silent performance of submarines was not as obvious as it seemed. In order to continue to improve the silence technology of submarines, major breakthroughs must be made in several areas, including "active noise control technology" If the previous silent technology is compared to passive stealth technology, then "active noise control technology" is active stealth technology. Judging by the exhibition of active stealth technology. "Active noise control technology" will surely replace passive mute technology and become the key technology for submarine stealth. It was also a breakthrough in this technology that the Republic spent a huge amount of money to build the "Manta Whale" attack submarine and spent several years testing the actual performance of the "Manta". As for the actual performance of the "Manta Whale", I am afraid that it is not optimistic, otherwise the Navy would not have repeatedly reduced the number of submarines built in this class. At one point, he even planned to abandon the construction work.

Not a technical expert though. He was not the first captain of the assembly chief of the "Manta Whale", but after working on the submarine for a few months, Xiao Jingbo had a very in-depth understanding of the "Mantahan".

The so-called "active noise control technology" is actually a method of noise cancellation using the principle of sound wave coherence.

The theory of this technique is very simple: i.e., it emits sound waves of the same frequency and intensity, but in completely opposite phases, so that the two waves cancel out completely.

It's easier said than done.

From written theories to real-world products, the Republic's scientists and engineers have spent a full number of years. That is, as early as the year of the blade. Scientists from the republic began to conduct relevant research. Although it is impossible to know how much time the United States spent in this field, it is certainly much more than the Republic, because as early as the beginning of the century, American scientists proposed a similar principle and considered the technology promising on submarines.

It can be seen that the strength of the "Bat" is not only a magnetohydrodynamic propulsion device.

According to Xiao Jingbo's information, after activating the "active noise control system", the "Bat Zuo" can be absolutely silent and will not radiate any noise to the outside.

Although this does not mean that the "Manta Whale" cannot be presented, for example, the active noise control system of the "Manta Whale" cannot interfere with the high-energy infrasonic waves generated by the active attack sonar, in addition, when the active noise control system is working, it will convert the energy of the sound wave into internal energy, so that the water temperature around the submarine is high, thereby exposing the whereabouts of the submarine. In previous tests, the anti-submarine patrol planes of the Republic Navy used thermal phasers to show the "Manhan" 10,000 meters below the sea surface, and the Navy also stipulated that the minimum diving depth of the "Manta" was phantom meters, and the photoelectric mast of the "Manta Whale" was lengthened to corn.

Thankfully. Not many people know that the "Manchai" is equipped with an active noise control system.

It's not hard to imagine. If the four find out the specific situation of the "Manta Whale", all US submarines will be equipped with thermal phasing equipment. The U.S. Navy will also intensify the research and development of thermal induction detection technology. Judging from the intelligence information obtained by the Military Intelligence Agency, the United States has not taken similar measures, which proves that the United States does not know about the situation of the "Manta Whale."

Unfortunately. The reliability of the active noise jamming system of the "Manta Whale" is very poor and does not work continuously.

In the eyes of the average person, noise control technology is much simpler and easier to implement than electromagnetic interference technology. At first, Xiao Jingbo also thought so, and after working on the "Bat Zuo" for a few months, he should now look the other way around. The ocean itself is a huge source of noise, and it is impossible to disturb all of it. It also makes no sense, because the result of disturbing all the noise is to vaporize the seawater around the submarine, turning the submarine into an extremely conspicuous heat source, even if there is no noise at all. It will also be very eye-catching. Therefore, in order for active noise control technology to be practical, it is necessary to find ways to identify the nature of the noise and only interfere with the noise that needs to be controlled, leaving the noise of nature alone. While this is primarily a software problem, it would take hundreds of software engineers more than a decade to write a computer program to collect the thousands of natural noises in the ocean, identify their main characteristics, and then treat them differently.

Arguably, the biggest problem with the "Bats" is that there are too many software vulnerabilities.

Since the launch of the sea trial in Libinian, the software for adjusting the active noise control system has been going on, and there are thousands of vulnerability patches alone.

Xiao Jingbo is not a software engineer, he doesn't need to know software technology, he just needs to know how to do it.

According to the indicators given by technical experts, in known sea areas, the active noise control system of the "Bat Zor" has to be re-entered into the control software every hour of operation, and in unfamiliar sea areas, it has to be done from scratch every hour. Prevent vulnerabilities in the control software from bringing the active noise control system down. Even so, it is impossible to measure when the vulnerabilities in the software will be affected, and the old Feigang noise control system may fail at any time.

For the dive micro-length, this annoying thing is the "uncertainty factor"

Imagine if the "Bat Zor" turned on the active noise control system in order to seize the advantageous attack position, and passed near the enemy ship as quickly as possible, and suddenly the noise control system failed, even if the captain immediately ordered the reduction, and the noise from the magnetofluid propulsion device was very low, in the case of close proximity to the enemy boat. The "Manta Jiao" will also be exposed to the enemy, and even more unfortunately, the "Manta" is grabbing positions and is not in a state of attack, so it will certainly not be able to shoot torpedoes in front of the enemy boats, and it wants to turn the situation around. One can only pray to avoid the torpedoes fired by enemy ships first.

In a sea trial shortly after launching, the "Bat" made a foreign appearance in front of the "Sea Lion". At that time, the captain of the "Manta Whale" just wanted to show off the active noise control system and scare the comrades-in-arms on the "Sea Lion", but when the "Manta Zo" maneuvered directly in front of the "Sea Lion" with high maneuverability, the active noise control system stopped due to overload, and the sudden loud noise almost made the "Sea Lion" regard the "Manta Whale" as a certain American submarine that suddenly killed It is quite possible that the captain of the ship, in accordance with the secret order issued by the submarine command, fired torpedoes at the "American submarine" that suddenly appeared.

There is no doubt that Xiao Jingbo does not want to repeat the mistakes of the past.

Exactly, at the time of the crossing. The submersibility of the "Batzo" has always been within the force section. In this range, even if the active noise control system is not used, the noise of the "Bat Zor" will not exceed the decibel level, and it is difficult for nearby submarines to detect.

The problem is that if the voyage is out of the festival, the noise of the "Bat" will be more than four points.

While this is still far below the background noise of the ocean, it is enough to expose the manta whale's whereabouts in the face of ever-changing passive sonar. Not to mention anything else, the "killer whale"-level towed passive sonar can detect the "manta whale" thousands of kilometers away, and determine the position of the "manta ray" when the distance is shortened to about a kilometer. The U.S. Navy's "Atlanta" class and the British Navy's "Fast" class have passive sonar comparable to the "Orca" class, and they are able to spot the "Bat" at a similar distance.

Of course, this does not mean that the "Bat Lock" is useless.

In the same situation, the "Manta Whale" even if it does not use towed sonar. It can also be used as an Atlanta-class attack submarine thousands of kilometers away. Even if the "Atlanta" class reduces the sailing degree below the old level, that is, controls the noise below the decibel level, the "Manta Whale" will be seen in advance when the distance is about 4,000 meters. In other words, with the use of more advanced passive sonar, the "Bat Zor" can be the first to appear before the enemy.

The problem is that American and British submarines don't necessarily need to maneuver around.

Xiao Jingbo is worried about this problem.

Although the U.S. and British navies are also "global navies" that have long eliminated electric submarines and are equipped with hybrid submarines, hybrid submarines are shutting down controllable fusion reactors; With only a composite battery, it can sit on the seabed for several days. In other words, if the U.S. and British submarines are deployed in advance, it is very likely that they will choose the tactic of waiting for the rabbit after reaching the waters near the Falklands. It is not necessary for all submarines to sink on the bottom of the sea, as long as one submarine sits on the bottom of the sea in the warring sea area that the "Manta Whale" must go to, or is suspended in the sea without making any noise, Xiao Jingbo can be given a pound when the "Manta Whale" passes by or attacks other submarines. "Surprise"

No matter how powerful the "Manta Whale" is, it is no match for heavy anti-submarine torpedoes.

After adjusting the route, Xiao Jingbo was still a little uneasy, and contacted the submarine command again to confirm whether the orders received were true. And whether there is any definite intelligence related to the front line.

Xiao Jingbo's reply from the submarine command was very disappointed.

The order was unmistakable, and there was no definite information about it, except that several British submarines had certainly reached the waters off the Falklands.

The so-called house leak coincides with a rainy day.

In the early morning of 24 July, less than an hour after the "Manta Whale" sailed, the passive sonar appeared its first target, a "Astute"-class attack submarine about 1 kilometer northeast of South Georgia.

When Xiao Jingbo returned to the command center. The sonar chief has confirmed the identity and route of the British submarine.

Fortunately, the British submarine went directly to South Georgia, and did not show the "Bat Ming, which was more than a kilometer away."

After tracking for several hours, and now that the other party had no intention of turning, Xiao Jingbo gave up the unexpected British submarine and let the "Bat Zuo" continue to move in the direction of the Falklands in the direction of the ugly festival.

Of course, Xiao Jingbo did not forget to report the situation. Unless there are enemy anti-submarine patrol planes and anti-submarine warships nearby, there is no need to worry that the release of the communication buoy will expose the whereabouts of the "Bat Chai."

Because Argentina did not send troops to capture South Georgia as it did more than half a century ago, the task of the British submarine was certainly not to transport special forces, but to establish the first line of anti-submarine defense east of the Falklands to guard against the possibility of Republic submarines at any time.

Deran's conclusion made Xiao Jingbo more cautious.

When there were still nearly a thousand kilometers away from the Falklands, he encountered a British submarine, which is enough to prove that there must be several British submarines in the waters near the Falklands, and Xiao Jingbo really has reason to believe that the U.S. Navy has sent submarines to participate in the war, and there is no reason for the Royal Navy to waste the already very limited submarine force fort

No matter how worried you are, the "Bat Guess" can't turn back.

The next three days. Xiao Jingbo has been staying in the command center, only occasionally dozing off.

Present on the road. It made him feel more and more like a self-defeating net.

In addition to encountering British submarines in the early morning of the same day, they encountered three British submarines and a ruthless American submarine in the afternoon and night, the morning and evening of 10,000 days, and the early morning of the sun.

Other words. The United States and Britain sent their best submarines.

The morning of the next day. Xiao Jingbo received the latest combat order from the Submarine Command: to go to the warring waters north of the Falklands to ambush and ambush nearby British and American submarines. Although the order clearly mentions that it can wait until the British and American submarines sneak attack the Argentine transport convoy, there is no need to consider the safety of the fleet. But the order also mentions that in the event of an attack by British and American submarines, there is no escape. Make sure that the submarine does not fall into the hands of the enemy.

Xiao Jingbo did not waste time, and immediately announced the combat order issued by the submarine command.

None of the officers and men on the "Bat Zor" were surprised, and in any case, the voyage "traveled 10,000 kilometers." Never come over to see the excitement. Besides, the submarines of the republic do not have the tradition of watching the lively. 、

The positive attitude of the officers and soldiers reassured Xiao Jingbo, after all, fighting spirit is more important than anything else.

As the "Bats" approached the war zone, Xiao Jingbo had to force himself to sleep.

Knife day and night. When he returned to the command center, the passive sonar of the "Manta Whale" appeared again to whip the "Atlanta" class attack submarine of the US Navy. What's more, these three U.S. submarines and the current U.S. submarines are also heading north. In other words, the Submarine Command must have received accurate information about the sea area where the other side would intercept the convoy heading to the Falklands, otherwise it would not have notified the "Bats" in such a timely manner.

Thankfully. Xiao Jingbo's experience has helped a lot.

Because of the use of higher navigation before this, when entering the sea area of engagement, the "Bat Zor" was able to control the navigation degree below the force joint. In other words, in the case of noise that is less than a decibel of Tian, Xiao Jingbo does not have to worry too much about being discovered by nearby enemy boats, and can arrange tactics relatively casually.

Unfortunately. The number of enemy ships far exceeded Xiao Jingbo's estimate.

10,000 nights. When the passive sonar of the "Batzo" detected the noise coming from the convoy from many kilometers away, and Xiao Jingbo ordered to reduce the degree to the mouth section, there were already as many as seven submarines in the vicinity. One of them is the "Atlanta" class of the US Navy, and only the thug ship is the "fast" class of the British Navy.

It's obvious. The American and British submarines did not want to risk their lives and intended to tackle the Argentine fleet with anti-ship missiles at a distance of several hundred kilometers.

The problem is that the American and British submarines have not yet entered the attack position, that is, the battle will not explode immediately, and it is very likely to drag on until the early morning of the flight day, or even the morning of the flight day. In this way, if the US and British navies believe that more than 8o anti-ship missiles fired at a time by seven submarines are not enough to solve the problem, they will send more submarines.

In fact, Xiao Jingbo also believes that the US and British navies are very likely to send a number of old submarines.

Although the Argentine fleet only has to move frigates, in order to deal with the frigates equipped with forced electromagnetic interference devices and electromagnetic guns, it is necessary to carry out at least three attacks with multiple anti-ship missiles of the thugs. In order to avoid being attacked by aviation anti-submarine forces, the US and British submarines participating in the attack must simultaneously fire anti-ship missiles, and by setting different attack routes, the anti-ship missiles will attack the Argentine fleet in batches. In this way, it is not only necessary to put in more than one old attack submarine, but also to shorten the attack distance to about one kilometer.

Obviously, the "Manta Whale" was in an awkward position.

Even if the "Manta Whale" is the most advanced attack submarine in the world, it is not realistic to deal with more than one old opponent at the same time. You know, in the case of a generation difference, it is very good to be able to do one against four. In previous submarine warfare, the republic's submarines attacked enemy ships at most once. What's more, the "Bat Zor" has only 4 fire control channels, and can only attack the enemy boat at a time. Of course. As long as Xiao Jingbo does not lose his mind, he will not attack first in front of his old opponent.

Only one thing is certain, with the performance of the "Manta Whale", as long as it does not make a move, it will not be revealed.

At a time when all the officers and men of the boat were eagerly looking forward to establishing their combat exploits, Xiao Jingbo was thinking about whether to let go of the "opportunity" in front of him and wait until the opponent ambushed the Argentine fleet before looking for an opportunity.

To this end, Xiao Jingbo must clearly consider a question, that is, the true meaning of the republic's navy's personal action.

It is certainly impossible to participate in the war, otherwise it will not be submarines, but aircraft carrier battle groups.

Since it is impossible to participate in the war, then there will be no open action, and there is no need to deal with the Yankees, after all, the Yankees are strong enough that the "Manta Whale" alone will not be able to turn the sky.

To deal with. It's just the British.

Thinking about this truth, Xiao Jingbo knew what to do.

When he looked up, several officers who were waiting a little impatiently immediately looked at him. After coming into contact with the captain's gaze, those officers knew that this ace captain, who was known for his steadiness, once again waved his specialty, and would not act rashly when the situation was unclear.
