When Xiao Jingbo looked at the corner of the screen, he said

Beijing time Feiri thugs 4:00 Feng. The Malvinas Islands is Feiri 2:00 Feng, or Buenos Aires time reef Feng.

"Record the noise source."

“Recording is underway

Xiao Jingbo nodded to the sonar and his eyes fell on the fire control screen again.

With the US and British submarines lurking around, the icons on the screen changed from dark yellow to bright yellow, and they were marked with important parameters such as distance, depth, speed, and heading. Although in normal submarine, the target's orientation and approximate distance can be determined by the noise intercepted by passive sonar, it is difficult to accurately locate the target, especially in the case of a long distance, it is difficult to provide accurate fire control data by passive sonar, otherwise the submarine does not need to be equipped with active sonar. If you want to use passive sonar for accuracy.

Positioning is not impossible, but the target needs to make a lot of noise. Because submarines cannot use active sonar at all times, they always rely on passive sonar to obtain external information. Therefore, submarines must not only minimize noise to avoid being discovered by their opponents, but also try to improve the sensitivity of passive sonar to discover opponents in advance. In actual operation, Kuangweiweichang likes to arrive at the combat waters first and lurk, and wait until the enemy comes to the door to die, in order to minimize the noise emitted by the boat and find opportunities to kill the opponent.

What Xiao Jingbo wants is the opportunity in front of him.

The US and British submarines began to attack the Argentine fleet in the distance. Even if the submarines themselves were very quiet, they did not even make any noise. They would produce very obvious noise when launching torpedoes and missiles.

Of course, this cannot completely determine the exact location of the enemy boat.

The huge noise will be generated when launching torpedoes and missiles for a long time and has long been highly valued by the navies of various countries. The navies of various countries have also come up with many solutions, such as the launch method of self-driving pipes. However, these methods have not solved all problems. For example, the launch method of self-driving pipes can only be used to launch torpedoes. Moreover, due to the firmness of the tail cover of the torpedo launch pipe, the maximum combat depth is greatly limited. More importantly, in order to reduce noise, the initial speed of the torpedoes is very low, which seriously limits the maneuverability of the torpedoes. In an emergency, in order to take the lead in attack, the submarine will increase the speed of the torpedoes, thus making the launch method of self-driving pipes meaningless.

Relatively speaking, the noise generated when launching the missile is more obvious.

At the beginning, the missiles on the attack submarines, which did not include cruise missiles, were installed in special containers and launched from torpedo tubes. It was not until the second batch of the "Luo Alan" class that started from the old "Providence" class adopted vertical launch tubes. Before the "Drowned Whale" class, attack submarines in various countries, especially nuclear submarines and all-electric submarines, generally adopted vertical missile launch systems. The "Drowned Whale". Class opened an era. For the first time, this type of submarine adopted a "underwater integrated launch system" that can be assembled according to the task needs according to the modular design concept. It adopted an "underwater integrated launch system" that can be assembled according to the mission needs. Since then, submarines in various countries have adopted similar design methods. The "underwater integrated launch system can be quickly promoted and popularized. One important reason is that the noise generated when launching missiles is much smaller.

Because the "underwater integrated launch system" is a "ammunition module built separately." The deployment method is more flexible. When engineers from various countries design submarines, they almost always place the module behind the dock enclosure. Therefore, when launching missiles, they do not need to worry about collide with the dock enclosure. They can choose a lower outlet speed, so they choose a quieter launch method such as "hydraulic mechanical power".

The problem is that reducing noise does not mean canceling noise.

Actual measurements have proved that when launching missiles, it is still the most uneasy time for submarines.

In fact, it is precisely because there is a lot of noise when launching missiles, so there is no big catty. The captain is willing to use missiles first in combat. Even in relatively safe waters, the captain will first try to shorten the distance and use torpedoes. Only when there is no choice will the captain be used.

.

Are there no choices for submarines in the United States and Britain?

Xiao Jingbo must consider this issue and must consider it clearly.

In the intelligence sent by the Submarine Command, the submarines of the Royal Navy had intercepted the first fleet sent by Argentina a few days ago, sunk three escort warships with Yubei, and moved electric submarines and fast merchant ships. In the subsequent battle, the British Navy's attack submarines and the fierce Republic's electric submarines sank one after another, and only the thugs survived.

After receiving this message, Xiao Jingbo was thinking repeatedly.

It can be seen from this news that the Royal Navy's submarines are stronger than the Argentine Navy and have the ability to ambush the transport fleet to the Cabernet Island to deal with escort ships. There is no doubt that the US Navy's submarines also have this ability, which can completely shorten the distance and use torpedo to kill the opponent. The US and British submarines did not choose to shorten the distance. Instead, they used missiles several hundred kilometers, not afraid of the two escort warships, but the Republican submarines that may appear at any time. The problem is that the noise emitted by the missile can be heard hundreds of kilometers away, thus exposing the location of the US and British submarines. The Republican Navy's submarines will definitely not follow the Argentine fleet south, but will sail in front of the fleet. In other words, the US and British submarines choose to take action when they are far from Jinduo, which cannot guarantee their own safety.

Obviously, this violates the primary combat principle of submarines.

Due to the limitations of submarines and submarines, that is, submarines are very likely to sink after being attacked, and they will sink! The survival rate of compensation for Lianbei is almost zero. When any submarine is commanding a battle, the first thing to consider is its own safety, rather than fighting against the enemy.

The actions of the US and British submarines can only convince Xiao Jingbo that there must be several submarines nearby that did not participate in the attack.

The other party in the ambush sea area chooses, so the US and British submarines have enough time to arrive at the battlefield in advance. They also find the ideal ambush location, then shut down the reactor, and wait for the Republic's submarines to fall into the trap when they are powered only by batteries.

Xiao Jingbo was almost sure that as long as the "Faozou" took action at this time, the US and British submarines that acted as bait would be hit by the enemy's torpedoes before the torpedoes were gathered. There is no doubt that if the "Faozou" was to be extremely expensive, the US and British navies would have to pay an extremely high price to exchange it with at least four attack submarines. The problem is that the "Faozou" is a unique submarine, and the US and British navies not only want to kill the "Faozou," but also want to seize the evidence that the Republic intervened in the Cambodia conflict. In other words, the "Faozou" has something that the "Faozou" has. The Republic can only suffer a loss and watch Argentina fall in front of the United States and Britain.

It can also be seen from the combat orders sent by the Submarine Command that "The Bat Whale must not be missed."

Considering this problem, Xiao Jing took a breath and looked up at several officers.

"Old Xiao, it's the time now"

"Wait a minute. We are not here to fight Qiufeng." Xiao Jingbo sat down and closed his eyes.

.

The deputy captain Han Anbang, who spoke, hesitated for a moment, sighed secretly, and shook his head at the other officers.

Although most of the officers and soldiers on the "Bat Whale." were carefully selected, and each person had practical experience. On average, each person had received more than two combat medals, after Zhang Xuefeng left the front line, Xiao Jingbo was recognized as the number one captain. In front of him, those experienced submarine soldiers were nothing. Besides, the submarine troops were "one-manager" and the captains said, and the officers and soldiers below did nothing.

The restlessness quickly passed, and Xi, his face soon became quiet.

Under normal circumstances, the U.S. Navy's Atlanta-class attack submarine is generally equipped with ground-to-ground cruise missiles and anti-ship missiles in the vertical launch system. It is also equipped with micro-anti-ship missiles in the ammunition compartment. That is to say, in an attack, the Atlanta-class can launch at most old anti-ship missiles; because the submarine will carry ammunition according to the maximum standards when going out to sea, and the captain rarely chooses to load anti-ship missiles in the torpedo tube. Even in sea-making operations, the captain will retain several torpedo tubes in the torpedo tubes. Therefore, in case of no absolute necessity, the attack submarine will only use anti-ship missiles in the vertical launch system. It is rare to use the torpedo tubes to launch anti-ship missiles.

The situation of the British Navy's "Fast" class attack submarine is similar to that of the "Atlanta" class, and it also has a vertical missile launcher. However, the British Navy does not have the powerful long-range strike capability as the US Navy, so the British Navy's "Fast" class attack submarine generally carries old ground-to-ground cruise "Brother bullets and 8 anti-ship missiles. That is to say, without using torpedo launchers, the "Fast" class can launch 8 anti-ship missiles at a time.

According to the information intercepted by passive sonar, there are a total of 7 "Atlanta" class and thugs nearby.

"Fast" level.

In other words, this submarine can fire at most an anti-ship missile in an attack wave. Even if it does not use a torpedo tube, it can still fire the Zhaomei anti-ship missile.

Soon, a number appeared on the screen.

"Light" This is the situation recorded by passive sonar. That is to say, the eight nearby submarines launched a total of thugs. The submarines did not use torpedo tubes to launch anti-ships.

bomb.

Seeing this number, Han Anbang, who was still very excited at first, calmed down a little.

As the naval major who is most qualified to replace Xiao Jingbo and become the third captain of the "Baobao", Han Anbang followed Hua Jianfeng, Le Jiacheng, Liu Haifeng and Zhang Xuefeng on the broken submarines one after another, and participated in many naval battles, starting from the grassroots non-commissioned officer to become an intermediate officer. His submarine warfare will not be worse than other captains.

It is obvious that the American submarine is "used with both punches and feet." Only that British submarine has some reservations.

As long as Han Anbang calms down, he should know that there must be problems with this.

Just as Xiao Jingbo was worried, the eight submarines that "exposed" were just bait.

Although using anti-ship missiles to attack fleets that are many kilometers away, no matter how loud it sounds, it will not be threatened, and there is no need to leave a few torpedoes to prevent accidents, without considering underwater threats, the first choice of US and British submarines is to wait for the fleet to approach and launch an attack with torpedoes instead of collective appearances. US and British submarines are eager to attack, proving that they are not considering the threat from underwater, but fully considering the potential enemy. In this way, there is no reason for the seven US submarines not to leave one or two torpedoes in the torpedo launch tube. There is no doubt that the "fast" class plays a tiny role. If Xiao Jingbo issues an attack order, the first thing to do is to deal with

The one who paid for the British submarine, and first dealt with four targets in a quiet launch method, took this opportunity to reload the torpedo. When the American submarine found that it was attacked, the "Baozou" had already launched the second batch of torpedoes. Although it is not very likely to kill 8 enemy boats at a time, as long as you fire the torpedo first, you can force the opponent to give up the counterattack and avoid fish first. The "Baozou" can take this opportunity to escape! Good luck or transfer the array, the quasi-sale value-value attack is the second attack. Even if you take a step back, it is not the "Baozou" that enters the South Atlantic, but a "Killer Whale. Class attack submarine, which can also use the same tactics, and then escape when the opponent avoids the torpedo.

As long as the captain of the American submarine is not a fool, he should understand this truth.

The American submarine took risks and could only prove that there were several submarines nearby.

Because Xiao Jingbo did not issue an order, the "Baohan" did not take action. Soon, the US and British submarines that launched missiles left the ambushing waters and scattered at a relatively quiet speed. Because characteristic noise from US and British submarines had been collected, the central fire control computer of the "Baosa" could determine the approximate position of the US and British submarines based on the noise signals intercepted by passive sonar.

The US-British submarines did not go far, but were scattered within a radius of dozens of nautical miles.

This situation once again proves that Xiao Jingbo's judgment is accurate. If there is no other purpose, after ambushing the Argentine fleet, there is no reason for the US and British submarines to stay.

For the officers and soldiers on the "Faozou", patience is more important than anything else.

Waiting patiently quickly achieved results.

When the reading on the clock became a bad point, several blurry signals appeared on the fire control screen.

At this moment, Xiao Jingbo, who had been closing his eyes to rest, suddenly opened his eyes and looked at the sonar.

"The target data is being calculated." Sonar breathed a long breath, obviously startled by the captain's reaction.

Han Anbang was also shocked by Xiao Jingbo's actions, and even suspected that Xiao Jingbo had a sixth sense. You should know that in addition to a few violent sounds, whether it is a submarine or a large marine life, it emits infernal sound waves that cannot be heard by human ears. At this time, the submarines outside emit infernal sound waves. Even if the sonar is long, they can only hear the sounds transformed by the instrument, rather than the sounds made by the enemy boat. Xiao Jingbo is not a sonar, but has been closing his eyes to rest. However, he can react when the enemy boat appears, which is difficult to understand.

"It's an enemy boat!" Captain Sonar glanced at the captain and displayed the data on the fire control screen.

.

Xiao Jingbo glanced at Han Anbang and sneered.

Seeing the data on the screen, the deputy captain frowned slightly.

There are 4 targets in total, 3 of which are the Atlanta-class attack submarines. The target with the weakest signal has no corresponding identity, which means that it is a submarine that has never appeared before.

"It seems that the South Atlantic Ocean has become a big stage for advanced submarines in various countries." Xiao Jingbo smiled and said, "Those "fast, class will not be mentioned. I just met Him a few days ago, and now I have met another one. I see a hundred yuan, which is a US Navy attack submarine.

Han Anbang smiled and shook his head, saying, "No one bets with you, I think it's an American submarine."

The other officers had the same view, and no one bet on Xiao Jingbo.

"The fun is also ongoing. We missed the best time, so we just make a mistake." Xiao Jing gave a long breath, glanced at the officer around him, and said, "Although we can attack four targets at once, we must figure out our identities and be a little patient."

Han Anbang nodded and expressed his support for the captain.

"" is a temporary submarine for unknown submarines without classification. According to the rules of the Republic's Navy submarine force, if a boat is encountered, the captain's primary task is not to sink it, but to collect relevant information, especially characteristic noise, and bring this information back to the submarine command. The greatest significance of this rule is that, except for a very small number of test submarines, there are few submarines of individual class. In other words, there may be a large family with dozens of members in front of each. Only by timely understanding its specific performance can it gain the upper hand in future confrontations. Of course, this is not only the rule of the Republic's Navy, but also the rule of the US Navy. Otherwise, the US Navy would not have used many old attack submarines to find the traces of the "Swordfish".

"Preparing to start the noise control system, Xiao Jingbo stood up, "Reset the route, go back to the back of the butt first, and then find a chance to get closer. Prepare the underwater robot, if you have the chance, give a few close-ups and close-ups to make a pound. The album."

Hearing the captain's words, the officers in the command center laughed.

Because you have to live in a confined environment for several months, if you don’t know how to “enjoy in time”, even if you are strong in your will, you will be driven crazy by a claustrophobic environment. Therefore, submarine soldiers know how to find ways to create a relaxed atmosphere without conditions.

Xiao Jingbo is a relatively muscular captain, and he can also say a few cold jokes.

As the active noise control system began to work, the "Fuzou" became a "noise black hole in the depths of the ocean." Although this state did not last long, Xiao Jingbo only needed a few hours. No matter how advanced the submarine was, there was a blind spot for passive sonar surveillance. As long as you go behind the butt, the active noise control system can be turned off and the navigation can be followed at a lower speed. The most valuable information is gathered.

Xiao Jingbo didn't feel relaxed because he knew that it was very likely to be a submarine equivalent to the "Baohan".
Chapter completed!
