At the first sound, Xiao Jingbo glanced at the left corner of the screen

Beijing time flying day hitter 4 o'clock Feng minutes. 【Full text reading】The Malvinas Islands is the 2 o'clock Feng minute of the flying sun, or the Buenos Aires Time Reef Feng fen.

"Record the source of the noise."

"Recording

Xiao Jingbo nodded at the sonar chief. Eyes fell on the fire control screen again.

As the US and British submarines lurking around made their moves, the icons on the screen changed from dark yellow to bright yellow, and important parameters such as distance, depth, navigation, and course were marked one after another. Although the location and approximate distance of the target can be judged by the noise intercepted by passive sonar under normal submersible conditions, it is difficult to accurately locate the target, especially in the case of long distances, it is difficult for passive sonar to provide accurate fire control data, otherwise the submarine does not need to be equipped with active sonar. It's not impossible to use passive sonar to accurately locate the target, but you just need to make the target louder. Because submarines cannot use active sonar at all times, they rely on passive sonar to obtain external information. Therefore, the submarine should not only reduce the noise as much as possible to avoid being seen by the opponent, but also try to improve the sensitivity of the passive sonar to show the opponent in advance. In practice, the dive and the commander like to reach the combat area first and lurk, and wait until the enemy takes the initiative to send him to death, just to minimize the noise of the boat and find an opportunity to kill the opponent.

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

American and British submarines began to attack the Argentine convoy in the distance, even though the submarines themselves were so quiet that they didn't even make a little noise. When firing torpedoes and missiles, there is a very noticeable noise.

Of course, this also does not fully determine the exact location of enemy ships.

It has long been a tradition of making loud noises when firing torpedoes and missiles, and has long been highly valued by the navies of various countries, and the navies of various countries have also come up with many solutions, such as the use of self-propelled and out-of-tube firing methods. However, these methods do not solve all the problems, such as the self-propelled tube firing method can only be used to shoot torpedoes. Moreover, due to the firmness of the tail cover of the torpedo tube, the maximum combat depth is greatly limited. What's more, in order to reduce noise, the initial degree of the torpedoes of the self-propelled tube is very low, which seriously limits the maneuverability of the torpedo. In an emergency, in order to preemptively attack, the submarine length will improve the torpedo navigation, so that the self-propelled method of firing will be meaningless.

Comparatively speaking, the noise produced when firing missiles is more noticeable.

Initially, attack submarines did not include cruise missiles, and the missiles on submarines were fired from torpedo tubes in special containers. It was not until the second batch of the "Lotrot" class, starting with the old "Providence", that a vertical firing tube was adopted. Before the "Killer Whale" class, attack submarines of various countries, especially nuclear submarines and all-electric submarines, generally adopted missile vertical firing systems. "Killer whales. The class ushered in an era when submarines of this type, in accordance with the modular design concept, adopted a "combined underwater launch system" that can be assembled according to the needs of the mission, which is used to fire not only missiles but also torpedoes. Since then, submarines of various countries have adopted a similar design approach. "Underwater integrated fire system. An important reason for the rapid popularization and popularization of missiles is that the noise generated when firing missiles is much smaller.

Because the "underwater integrated fire system" is a separately built "ammunition module." "The deployment method is more flexible, when engineers from various countries design submarines, almost all of them place the module behind the command station enclosure, so when firing missiles, there is no need to worry about colliding with the command station enclosure, and you can choose a lower outlet degree, so as to choose a quieter launch method such as "hydraulic mechanical power".

The problem is, reducing noise is not the same as canceling it.

Actual measurements have proved that when firing missiles. It's still the least quiet time for submarines.

In fact, it is precisely because of the loud noise produced when firing missiles that there is no catty, and the captain is willing to use missiles first in battle, even in relatively safe sea areas, the captain will first try to shorten the distance and use torpedoes, and only when there is no choice, will the missile be used.

Didn't the American with British submarines have a choice?

Xiao Jingbo must think about this issue, and he must think about it clearly.

The Submarine Command clearly mentioned in the incoming intelligence that the submarines of the Royal Navy had intercepted the first fleet sent by Argentina a few days earlier, and sank three escort warships, electric submarines and a fast merchant ship with Yubei, and in the ensuing battle, an attack submarine of the British Navy and an electric submarine of the Republic Navy were sunk one after another, and only the thug Qiang survived.

After receiving this news, Xiao Jingbo was thinking about it repeatedly.

As can be seen from the message. The submarines of the Royal Navy are more powerful than those of the Argentine Navy, and are capable of ambushing convoys bound for the Falklands against escort ships. There is no doubt that the submarines of the US Navy also have this ability, which can completely reduce the distance and take out the opponent with torpedoes. American-British submarines did not choose to shorten the distance. Rather, the missiles are used from a distance of several hundred kilometers, not to be afraid of those two escort warships, but to the submarines of the Republic that may appear at any time. The problem is that the noise from the use of missiles can be heard from hundreds of kilometers away, thus revealing the location of the US and British submarines. The submarines of the Navy of the Republic will certainly not follow the Argentine fleet south, but will sail ahead of the fleet. In other words, the fact that the US and British submarines chose to strike at a distance of many kilometers could not guarantee their own safety.

Obviously, this is contrary to the principle of the submarine's combat.

Restricted by submarines and submarines, that is, submarines are very easy to sink and sink after being attacked! The survival rate of the loss is almost zero. When any submarine commander is in command of a battle, the first thing to consider is his own safety, not to fight for the enemy's life.

The actions of the American and British submarines only convinced Xiao Jingbo that there must be a few submarines nearby that did not participate in the attack.

The ambush of the sea area was chosen by the opposing side, so that the American and British submarines had enough time to arrive on the battlefield in advance. And find the ideal ambush site, then turn off the reactor and, powered only by batteries, sit back and wait for the republic's submarines to fall into the net.

Xiao Jingbo was almost certain that as long as the "Manta" made a move at this time, it would be hit by the enemy's torpedoes before the torpedoes concentrated on the American and British submarines that were acting as bait. There is no doubt that in order to take out the "Bats", the US and British navies will need to pay an extremely high price, and at least four attack submarines will have to be exchanged. The problem is that the "Batzo" is a one-of-a-kind submarine, and the US and British Navies not only want to take out the "Batzo". and also wanted to seize evidence of the Republic's involvement in the Falklands conflict. In other words, the "manta whale" has three longs and two shorts, and 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 order from the submarine command, "Manta whales." There must be no mistakes.

Take into account this catty. Question, Xiao Jing took a breath and glanced up at several officers.

"Old Xiao, now is the time"

"Wait. We're not here to fight the autumn breeze. Xiao Jingbo sat down and closed his eyes.

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

Although "manta whales. Most of the officers and men on the ship were carefully selected, each of them had actual combat experience, and each of them had won more than two combat medals on average, but after Zhang Xuefeng left the front-line troops, Xiao Jingbo was recognized as the number one captain, and in front of him, those experienced submariners were nothing. Besides, there is absolutely no reason for the submarine force to say what the captain of the submarine force says, and the officers and men below will do it.

The restlessness passed quickly, and the evening and noodles soon quieted down.

The attack submarines of the "Atlanta" class of the US Navy under normal conditions. Generally, the vertical launch system is equipped with mouth-to-mouth ground-to-ground cruise missiles and mouth-shot anti-ship missiles. And in the ammunition compartment is loaded with micro-anti-ship missiles. That is, in one attack, the "Atlanta" class is capable of firing at most old anti-ship missiles; Because submarines carry ammunition according to the maximum standard when going to sea, and the captain rarely chooses to load anti-ship missiles in the torpedo tube, even in sea supremacy operations, the captain will keep a few torpedoes in the torpedo tube, so in the absence of absolute necessity, the attack submarine will only use anti-ship missiles in the vertical firing system. Anti-ship missiles are rarely fired from torpedo tubes.

The situation with the British Navy's "Fast" class attack submarines is similar to that of the "Atlanta" class, which also has a vertical tube for a missile. It's just that the British Navy does not have the same powerful long-range strike capability as the US Navy, so the British Navy's "fast" class attack submarines generally carry old ground-cruising "brother bombs" and 8 anti-ship missiles. That is, without the use of torpedo tubes, the "fast" class can fire 8 anti-ship missiles at a time.

According to information intercepted by passive sonar, there are a total of 7 "Atlanta" class and thug ships in the vicinity

"Fast" level.

Other words. This mobile submarine can shoot up to one anti-ship missile in one attack wave, and even if it does not use torpedo tubes, it can also shoot anti-ship missiles.

After a while, a number appeared on the screen.

"Light" This is what was recorded by passive sonar. Other words. In total, 8 submarines in the vicinity shot thugs, and submarines did not shoot anti-ships with torpedo tubes

Play.

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

As the naval lieutenant who is most qualified to replace Xiao Jingbo and become the third captain of the "Bat Bao", Han Anbang has followed Hua Jianfeng, Le Jiacheng, Liu Haifeng and Zhang Xuefeng in breaking submarines, and has participated in many naval battles, starting from the most basic non-commissioned officer until he became a middle-level officer, and his respect for submarine warfare will not be worse than that of other captains.

It's obvious. American submarines are "fists and feet." "Only that British submarine has reservations.

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

Just as Xiao Jingbo feared, the 8 submarines that "outcropped" were just bait.

Although with anti-ship missiles to attack such as the flotilla many kilometers away. No matter how loud the noise is, there is no threat, and there is no need to leave a few torpedoes in case of accidents, but without taking into account the underwater threat. The tactics of the U.S. and British submarines were to wait for the flotilla to approach and attack with torpedoes, rather than making a collective appearance. The rush of American and British submarines to attack proved that they did not fail to take into account the threat from underwater, but fully considered the potential enemy. In this way, there is no reason why 7 American submarines should not leave one or two torpedoes in their torpedo tubes. There is no doubt that the "ship" is fast. If Xiao Jingbo gave the order to attack, the British submarine would be dealt with first, and it would first deal with four targets in a quiet way, and take this opportunity to reload the torpedoes. Although it is not very likely to take out 8 enemy ships at once, as long as you shoot the torpedo first, you can force the opponent to give up the counterattack and avoid the fish first, and the "Bat" can take this opportunity to slip away! Daji. Or if you transfer the array, you will be able to attack the second time. Even if you take a step back, it is not the "manta ray" that enters the South Atlantic, but a "killer whale." The same tactics can be used for attack submarines, and then slip away while the opponent is avoiding torpedoes.

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

The American submarine made a desperate move, which only proves that there are several more submarines nearby.

Because Xiao Jingbo didn't give an order, "Bat Han." No action was taken. Not long after, the US and British submarines that had fired missiles left the ambush area and scattered in relative peace. Because the characteristic noise of the American and British submarines has already been collected, in the next few hours. The central fire control computer of the "Bat Zor" was able to confirm the general orientation of the US and British submarines based on the noise signals intercepted by the passive sonar.

The American and British submarines did not go far, but spread within a radius of tens of nautical miles.

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

For the officers and men of the "Bat Zor", patience is more important than anything else.

Patience quickly paid off.

When the readings on the clock turned into a sting, several vague signals appeared on the fire control screen.

It was also at this time that Xiao Jingbo, who had been closing his eyes and recuperating, suddenly opened his eyes and looked at the sonar chief.

"Target data is being measured." The sonar let out a long breath, apparently startled by the captain's reaction.

Han Anbang was also taken aback by Xiao Jingbo's movements, and even suspected that Xiao Jingbo had a sixth sense. You must know that except for a few violent sounds, whether it is a submarine or a large sea creature, it is infrasound waves that cannot be heard by the human ear. At this time, the submarines outside are infrasound, and even if the sonar is long, they can only hear the sound transformed by the instrument, not the sound of the enemy boat. Xiao Jingbo is not a sonar leader, and he has been closing his eyes to recuperate. But it can react when the enemy ship appears, which is difficult to understand.

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

Xiao Jingbo glanced at the fire control screen and sneered. Han Anbang looked over.

Seeing the data on the screen, the co-captain frowned slightly.

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

"It seems that the South Atlantic has become a big stage for advanced submarines of various countries." Xiao Jingbo smiled and said, "Those few ships" are fast, let's not talk about the class, I only met each other a few days ago, and now I have met another one. I saw a hundred, and it was a U.S. Navy attack submarine

Han Anbang shook his head with a smile and said, "No one bets on you, and I also think it's an American submarine." ”

The other officers also had the same opinion, and no one bet against Xiao Jingbo.

"The excitement is also on. The best time was missed, and we simply got it wrong. Xiao Jing let out a long breath, glanced at the officers around him, and said, "Although we can attack four targets at a time, we have to figure out the identity, and we have to be a little patient." ”

Han Anbang nodded in support of the captain.

According to the rules of the submarine forces of the Navy of the Republic of China, if a submarine is encountered, the captain's task is not to sink it, but to collect as much information as possible, especially the characteristic noise, and bring this information back to the submarine command. The greatest significance of this rule is that, except for a very few test submarines, there are very few submarines of a separate class. In other words, there may be a large family with dozens of members in front of each rear, and only by figuring out its specific performance in time can it gain the upper hand in future confrontations. Of course, this is not only the rule of the Navy of the Republic, but also the rule of the US Navy, otherwise the US Navy would not have used many old attack submarines to look for traces of the "Swordfish".

Preparing to activate the noise control system, Xiao Jingbo stood up, "Reset the course, go around the back of the ass first, and then find a chance to get closer." Get ready for the underwater robot, and if you have the opportunity, give a few close-up close-ups and make catties. Album. ”

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

Because you have to live in a confined environment for a few months, if you don't know how to "enjoy in time", you will be strong-willed. will also be driven crazy by the claustrophobic environment, so submariners know how to create a relaxed atmosphere when there are no conditions.

Xiao Jingbo can be regarded as a captain who is more Muna, and he can also tell a few cold jokes.

With the active noise control system in operation, the "Batzo" became a "noise black hole" in the depths of the ocean. Although this state of affairs did not last long, Xiao Jingbo only needed a few hours. No matter how advanced a submarine is, the rear is a surveillance blind spot for passive sonar. As soon as you go around the back of the buttocks, you can turn off the active noise control system and follow the sail at a lower degree. Gather the most valuable information.

Xiao Jingbo did not feel relaxed, because he knew that it was very likely to be a submarine comparable to the "Bat Han".
