Many times, when promoting, they will talk about how long their history is, as if this is their seniority. In fact, if a hero does not mention his bravery in the past, the past is in the past and has nothing to do with the present.

For example, a certain car brand promotes how noble its bloodline is, and uses the banner of BBBA to the outside world. We are four German brothers. In fact, BBA has developed to this day and is still the most awesome existence and is synonymous with luxury cars.

But the newly added B is a defunct car brand. No matter how old it was, it is now defunct. It still promotes its past. This is purely misleading to consumers.

Fortunately, consumers are not stupid, so this B did not last long before disappearing into the long river of history.

Now, the same goes for building warships. The old brands are old brands, so what. They have never built a modern stealth ship. It is normal for them to make serious mistakes in design.

After hearing Qin Tao's words, everyone was filled with emotion. Yes, it is useless to talk about the past. It depends on the present. The Mingzhou Group has the most advanced shipbuilding technology now! Look at the tonnage of the warships launched by the Mingzhou Group in the past few years.

I know, let’s not talk about anything else, just aircraft carriers. How many countries in the world can build them?

"Many old brands should be put into museums." Longwayne said with emotion.

At this moment, suddenly, a voice sounded from the bridge.

"There's a noise under the water!"

"Attention, switch to anti-submarine operations immediately! Prepare to take off the anti-submarine helicopter!" After hearing the news, Ma Tieshan immediately became serious.

The motherland's navy has become stronger and will sail around the world, but at the same time, it will also cause unnecessary troubles. Some people always regard the peaceful rise of the East as a threat and will always cause trouble. They are on the water

We can't resist it, so we look for trouble underwater. Every time a warship goes to sea, it will be followed by its tail. It's the same now. Just after completing the drill, something nasty is following behind it underwater!

The Rainbow Nation naval officers present also became serious.

This is the territorial waters of their Rainbow Kingdom, and there are unexpected guests!

"Attention, order the shore-based anti-submarine troops to be ready and take off at any time!"

The Rainbow Nation's navy is very weak, and is still dominated by missile speedboats. Their surface forces do not have anti-submarine capabilities, but this does not mean that they can't do anything. They have shore-based anti-submarine forces that can be dispatched at critical times.

The surrounding speedboats dispersed. The missile boats did not have any anti-submarine capabilities and would only interfere with No. 526's anti-submarine operations. At this time, No. 526 had reduced its speed to about ten knots. At the same time, it released its towed sonar, and the anti-submarine helicopter took off.

The bridge was quiet, everyone was waiting for the sonar operator's report.

Although things were rushed, the sailors remained calm in the face of danger, which reflected their well-trained skills.

Different operations require different tactics. When anti-submarine, the warship itself cannot be too fast, otherwise its own noise will interfere with the monitoring effect of the sonar. At the same time, in order to better avoid the impact of the warship's own noise, the warship will also use

Towed sonar.

Tow the sonar several kilometers or even ten kilometers behind the warship, so that it can avoid the influence of its own noise. At the same time, towed sonar is also divided into two types. If you only tow a sonar detection device, this is the towed body.

If the sonar towed out are connected one after another to form a sonar array, that is a towed array sonar, and the effect of the latter will of course be better.

When building the 112 destroyer, towed sonar and anti-submarine helicopters were introduced from France, which greatly upgraded Dongfang's anti-submarine technology. However, in recent years, Dongfang's technology has developed rapidly, and towed sonar has also been upgraded to towed

array, the detection effect is better.

Moreover, this thing continues to develop. In the future, fiber optic technology will be further integrated to make the performance of this sonar array more advanced, making enemy submarines invisible underwater.

"The target is approaching, with a distance of twenty nautical miles and a speed of five knots." The sonar operator reported: "The sound characteristics are different from any submarine in the database. It is probably a submarine we have never encountered before."

Being discovered twenty nautical miles away is already considered a dereliction of duty. After all, at this distance, underwater submarines are already capable of launching torpedoes. However, it depends on the target. This is a submarine that has never been encountered before.

, the quietness is also quite good. If the crew of No. 526 were not well-trained, their existence might not have been discovered at all.

"Maybe it's a sea wolf." Longwayne said.

There are very few advanced submarines in the world, and even fewer are not included in the database of sonar devices. The Seawolf class should be one of them.

The design of this kind of submarine started during the Cold War, but when it was built, the Red Empire was no longer around. Due to the pursuit of high performance, the price of this kind of submarine was ridiculously high. In the 1980s, its currency value exceeded one billion US dollars.

Therefore, a certain country with deep pockets could not afford to build one, and the Red Empire was gone. They only built three, and then turned to building Virginia-class nuclear submarines with lower performance but cheaper cost.

There are only three Seawolf-class ships, and the naming is also very strange. They are named after animals and presidents. It was only after the Virginia-class that they received the serial number of the Los Angeles-class and returned to normal. This also shows how powerful the three Seawolf-class ships are.

The first Seawolf class was put into service in 1997, but navies around the world only knew of its existence and did not know where it was. Now, hearing that a nuclear submarine that had never been seen before was discovered underwater, Longwayne immediately thought of it.

Sea Wolf class.

However, Longwayen doesn't know whether it is.

"This is the waters of the Rainbow Kingdom. Now that we have encountered it, we cannot make our own decisions. Mr. Longwayne, what are your instructions?"

"We do not welcome uninvited guests, force them out, or drive them away!" Longwayne said: "Our shore-based anti-submarine troops will also join in at any time."

This chapter is not finished yet. Please click on the next page to continue reading the exciting content! "No, let's do it. This is just a small thing." Qin Tao said: "Now, I have an idea..."

"Okay, then just follow Mr. Qin's instructions!" Long Wayne said with excitement on his face.

The anti-submarine helicopter had arrived at the target sea area and dropped the sonar buoy. As a popping sound was heard, the underwater noise suddenly disappeared, as if it had never appeared.

No. 526 recovered the towed sonar and began to accelerate. The four diesel engines started at the same time, driving the propeller at the tail to rotate at high speed. The warship was getting faster and faster, fifteen knots, twenty knots, twenty-five knots!

It surged at top speed for half an hour and headed straight for the target sea area!

"Attention, slow down to ten knots and prepare the rocket depth charge launcher!"

The huge noise disappeared, and No. 526 resumed its anti-submarine mode, but at this time, it was ready for its killer move!

"Attention, the target is directly in front, a distance of three nautical miles, a fixed depth of fifty meters, twelve volleys!"

Whoosh, whoosh!

Suddenly, flames burst out from the bow of the ship. An anti-submarine rocket left the launch tube and released a long tail flame, followed by the second and third rockets. Just like the multiple rocket launchers on land, the bow of the ship

Soon it was completely surrounded by white smoke!

Viewed from the bridge, it is even more spectacular.

"Times are developing and technology is advancing. Many people think that rocket depth charge launchers are outdated, but we don't think that in modern times, they are still of great use, such as driving away underwater monsters." Qin Tao

Introduce it.

During World War II, this thing was very common. Even an armed transport ship had to squat two seats. After all, if there were no rockets to propel it, the warship would have to go deep into the sea area where the submarine was and directly release depth bombs. At this time, it would be easy to be attacked by the submarine.

attack.

Adding a rocket propulsion engine to the depth bomb and allowing the depth bomb to fly by itself can make warships safer.

It is low in cost and can be used in large quantities. After flying over, it will explode at a fixed depth under the sea water. Use this method of casting a wide net to catch big fish to attack the enemy's submarine. If you are lucky, after a few rounds, there will be waves coming from the underwater

After the explosion, diesel stains and some personal belongings will float on the water.

If you are unlucky, you may fire hundreds of them and there will be no reaction underwater.

During the Cold War, all countries felt that this thing was too primitive, so they began to fiddle with more modern things, completely replacing depth bombs with anti-submarine torpedoes. However, the East did not give up. No matter how advanced the warship was, it always had two doors on the bow.

The 054-class frigate uses two 6-tube WHH003A rocket depth charge launchers. Although it is an old weapon, it has undergone modern improvements. For example, it has added the SS01A digital follow-up system and the shipboard sonar system.

After detecting the target, it will immediately turn around without manual control and is more maneuverable. At the same time, it also uses a special 3200 depth bomb feeding device. After firing one round, it can automatically load the second round.

, after all, the Type 81 rocket depth bomb it uses weighs 74 kilograms. If it is loaded manually, it will be very labor-intensive. In harsh sea conditions, it may even be an impossible task.

Swish, swish, one round of rocket depth charges was completed, and the automatic loading device began to load the second round. The people on the bridge opened their eyes wide, looking at the big killer in the smoke gradually dissipating below.

"It actually reloads automatically?"

"Can we play the second round next?"

"That's right, if the things below still haven't responded, we'll do the second round. We have a total of five groups installed on the warship, so I don't believe it won't come out."

Anti-submarine warfare is all about patience, and Qin Tao has a lot of it. After more than ten minutes, there was no movement under the water, so the second round of rockets flew out again.

"It doesn't seem to have a very long range, right?" Anderson asked.

"Yes, the range is only three to four thousand meters. If you continue to increase the range, you will have to increase the size, which will reduce the bomb load and reduce the power of the warhead. Therefore, it depends on the military's choice."

Everyone nodded.

"No matter how far you go, you can hand over torpedoes, or even rocket-propelled torpedoes." Captain Ma Tieshan added.

"Yes, that's true, but it's not enough to just scare the enemy." Longwayne shook his head.

"It is only one of its tasks to scare underwater enemies. Its more important task is to intercept torpedoes. As you all know, it will be very troublesome once it is attacked by a torpedo. Conventional anti-aircraft missiles can only be used to intercept various anti-ship missiles.

There is really nothing you can do about underwater torpedoes. For our warships, if they find that a torpedo is coming, they will calculate various data. When the torpedo rushes over, they will launch anti-submarine depth bombs to construct an underwater defense circle.

, directly blow up the incoming torpedo."

Anti-torpedo!

In modern warfare, torpedoes are used less and less. This is of course because with the development of technology, the distance between the enemy and ourselves is getting farther and farther. It is increasingly difficult for torpedoes that can only attack close to have a chance to be launched. Even submarines

All have begun to use anti-ship missiles. However, this does not mean that torpedoes are not a threat. Once a torpedo is fired from somewhere, warships have no way to intercept it.

Anti-submarine rocket depth bombs provide this capability: an interception net can be constructed underwater to allow incoming torpedoes to detonate in advance!

Everyone present opened their eyes wide. Yes, anti-submarine rocket depth bombs can indeed do various things! Orientals are so smart.

"In this way, the weapons from the East are very good, much better than the German warships we ordered!"

"Yes, the design is mature and the weapons are diverse. It's really good. We should choose Eastern warships!"

"What about the orders from Germany?"

"Their design is flawed. Even if we don't want it, it's normal. We were almost cheated by them," said a naval officer.

Qin Tao was very satisfied. It seemed that the play was well performed.

"Report, a target underwater was found to be sailing at high speed and leaving this sea area."
