Red Alert Somalia

Chapter 647 Suspicious Sonar Signal

The departure of the Third Aegis formation is a huge boon for the sailors on the Hanoi submarine.

The detected warship was indeed a Somali navy warship or a powerful Somali Aegis warship.No country’s navy is unfamiliar with this arguably the best Aegis ship in the world.

A while ago, the Vietnamese side also saw the powerful combat effectiveness of this kind of warship. Although the missiles were not launched by the Vietnamese military, the ballistic missile defense capabilities that emerged from the Somali Navy’s defense of these missiles at that time really made everyone a feast for the eyes. Put.

And I think that during the naval battle in the Indian Ocean, the second ship of the US's most advanced Seawolf-class submarine was chased around the world by the Somali Navy’s anti-submarine forces. This shows the Somali Navy’s excellent anti-submarine capabilities.

Although Kilo-class submarines are known as black holes in the depths of the ocean, they really have no bottom on the true performance of this submarine.

When they were worried, the Aegis ship in Somalia immediately followed a series of actions that made them frighten. First they released the towed array sonar, and then the sonar buoy of the anti-submarine helicopter.

At that time, the captain was even ready to launch a torpedo. As long as he found the army was approaching the submarine's position, he would immediately order the torpedo pilot to launch a torpedo attack.

Fortunately, the seemingly series of actions quickly died down. When the sonarman told everyone that the Somali Aegis ship had moved away from the submarine, everyone seemed to breathe a sigh of relief.

To be honest, they are not optimistic about their own strength at all.

"Immediately reduce the speed. Just keep three knots." After seeing the danger has left, the captain finally said.When the submarine soldiers heard the captain speak, their nerves were a little relaxed.Obviously, it is safe now.

"It seems that this Somali warship just now must have discovered something. Fortunately, our speed is slow enough, and the submarine itself is very quiet, otherwise, we are all in danger. Now, it is not very safe here. Next Dive to two hundred and forty meters, hoping to really avoid the enemy's detection."

The captain explained to the people around.However, if you let him know that the Somali Navy has actually discovered the location of him and five other submarines, if it weren’t for an emergency order that depth bombs, anti-submarine torpedoes, and missiles had already come to them, I don’t know this boat. Long, what do you think now.Maybe it's a sigh of relief.But most likely is a stronger sense of crisis.

Now, he has admitted to the persuasion and took the initiative to lower his speed to maintain the safest and most economical sailing speed of three knots.Then use deep diving to keep yourself in a hidden state as much as possible.

It's just that they don't clear it out. Russia is a very interesting country.Weapons that are used outside will not only be weakened.The battlefield usage data will also be recorded.Especially submarines will record all submarine sonar signals.The reason is naturally very simple. There are no friends in the world, just in case.

The six Kilo-class improved submarines purchased by Vietnam from Russia naturally have the same treatment. Now, all the data of these six submarines have been sent to Li Lan by Putin, and the Somali Navy naturally discovered this all at once. Sonar signals from six submarines.

The real difficulty in sonar detection is to judge which one is a submarine from thousands of sonars. This cannot be replaced by instruments at all, but only to train the most skilled sonar personnel.And every sonar personnel must learn to filter the ocean and natural sounds, and then determine whether there is a submarine sound.

If the sonar signal of the submarine is known in advance, it is simple, it can save a lot of time, not to mention, it can also improve the probability of resolution.

Therefore, these six Vietnamese submarines have already been marked with bright marks in the Somali Navy. Once they appear in the sonar search range, as long as they are sailing underwater, there is no chance at all.Of course, if these six submarines enter the planned ambush position and sit on the bottom of the sea, it will be very difficult to find them.

And there is a very serious problem, which is why the sonar system on the Aegis ship can detect Vietnamese submarines so quickly, which is the result of the crowding of Vietnamese submarines.In modern naval battles, this kind of submarine crowding is definitely the most stupid tactic.

Modern submarines do not engage in wolves tactics, but book and plan to do so.The submarine of World War II sailed on the surface and dived during combat.If modern submarines do this, they will soon be sunk.

During World War II, submarines had no anti-submarine missions, and all targets were surface ships.The main task of modern submarines is anti-submarine. Although there are voice prints to identify the submarine model, the premise is that the sound can be heard clearly.In many cases, it is difficult to identify the enemy or friend of a submarine.Putting your two submarines together can easily cause confusion.

The navigating speed of modern submarines in the combat area is only about 5 knots, and it is easy to be found if the speed increases.Especially in the popularization of towed sonar arrays, the monitoring distance of underwater sound is very long.

At this speed, it takes too long to temporarily dispatch the submarine to the designated area. With this time, the airborne anti-ship missile has already solved the target, and the submarine is no longer needed.Coupled with the limitations of weapons during World War II.Submarines actually make up for the quantity and quality of surface ships, using small-tonnage submarines to achieve the combat capability of large-tonnage surface ships.

It is almost impossible for Germany to build a surface fleet capable of attacking the merchant fleet in the Atlantic Ocean.It can be done with a small-tonnage submarine, so a wolf pack tactic is used.

With current weapons, airborne anti-ship missiles can control a large area. Submarines have large tonnage, high cost, small number of weapons, and small control range.It is no longer suitable for the combat mission of anti-surface ships.

Low-speed and quiet submarines are suitable for attacking low-speed and quiet submarines.Therefore, the major countries in the world now don't expect to get any wolves.Because the submarine was formed into a pack of wolves, it happened to be a target for anti-submarine aircraft.Increase the chance of self-exposure. After all, sometimes a submarine cannot be found, but finding a group of submarines is a very simple matter.

The reason why Vietnam spends huge sums of money to buy these submarines is not to form a so-called wolf pack.Submarines are the naval equipment of choice for small countries in the world today to pursue "asymmetric" tactics-expecting the greatest deterrence capability with limited investment.

In response to the continuous improvement of the quality and quantity advantages of the Chinese Navy in the southern waters, Vietnam has begun to gradually adjust its military strategy in the South China Sea, trying to build a two-line battlefield and achieve a balance between North and South.

That is, while actively expanding in the central and northern parts of the South China Sea, focus on the construction of the southern South China Sea battlefield, especially the entrance of the Malacca Strait in the southern South China Sea, and the establishment of a submarine ambush area.

Now Vietnam’s tactical purpose has been achieved, but whether this submarine ambush area can be completed depends on good luck.

Hanoi, not everyone's face relaxed, there was one person who couldn't relax.That person was a sonar person with a sonar listener on his head, and his expression began to slowly become serious.

"The Somali warship is getting farther and farther away from us and has entered the Strait of Malacca." The sonarman said.His voice was very soft, obviously lowering the volume deliberately.And his words also really relax the people around him.

"However, I heard a very strange voice, very strange." The sonarman's next sentence made the atmosphere suddenly tense again.

"What's the sound?" The captain found the solemn and slightly confused look of the sonarman, and his heart naturally corrected.

The sonar shook his head and said: "Now I don't know, there is only one thing to be sure. The thing making this sound is not one, but a group. And it is approaching us, very fast."

"Then what did you hear?" The captain was also anxious.

"I don't know, it's like the sound of marine creatures, it looks big, but it doesn't look like the sound of a whale." The sonar was also very confused at the moment. He swears that this is the first time he has heard such a strange sound. Water ripple sound.

The captain didn't ask any more questions this time, but grabbed the earphone on the sonarman's head and placed it on his head. When he heard the strange sound, his brows couldn't help but frowned.

He hadn't heard this sound either, as if there were a lot of things approaching the submarine, and the speed was very fast, and the water ripple sonar was very diffused, to judge the size of the thing that produced the water ripple signal.

Hearing this sound, there is one thing that can be ruled out, and that is this suspicious watermark signal, not a mechanical sound.In other words, it has been possible to rule out the sonar signal brought by the suspicious submarine.

But since it is not a submarine, and its size is not small, what is it?In the captain's heart, a question similar to that of a sonar immediately appeared.

The water pattern signals are very scattered, and also very rhythmic, bursts, continuous, it seems a bit like the rhythm of octopus and squid swimming in the water, but how can there be such a big squid and octopus, even the world The biggest squid can't be in groups like this.

There are many doubts in my mind, and there is no clear answer. The earphones for monitoring sonar were returned to the sonarman, and the captain said: "Report the depth."

"The depth is two hundred meters, I am diving."

"What about other submarines?" The captain asked the sonarman this time.

"According to the sonar signal analysis, it seems to be aware that we are diving, and they are also diving." The sonar officer said.

"According to the plan, dive to a depth of 240 meters, and ignore the strange things. There are too many mysteries in the sea that we can not immediately see through." In the captain's view, as long as the opponent is not a submarine, everything is easy to say.
