Chapter 345: You still can't rely on outsiders for key equipment

For the Chinese Navy in 1997, if the air defense capability required Nuwa to patch up the sky, then the anti-submarine capability was still waiting for Pangu's creation—

Basically equivalent to non-existence.

As to how bad it is specifically...

In short, until the first decade of the 21st century, the propaganda of anti-submarine warfare in our military's propaganda materials mainly focused on the excellent hearing of sonar personnel...

The two warships Jingjiang and Rongzhou dispatched this time have neither anti-submarine helicopters nor towed sonar. Not only can they rely on hull sonar to search for submarines, but the only weapons that can attack submarines are rocket depth bombs...

In the entire South China Sea Fleet, only the "new" destroyer 166 Xiangzhou, which was commissioned six years ago, is equipped with a set of DUBV-43 towed variable depth sonar imported from France.

However, its main function is to conduct testing and technical verification. Due to the limited performance of the sonar itself and the huge noise of the ship, the actual submarine search capability is better than nothing, so that this set of things was directly dismantled during the modification after entering the new century.

Not to mention the torturous service capabilities of the 051 series ships, the 166 ship is currently in the maintenance and overhaul period after the last voyage and is simply unable to perform this mission.

After hearing the news, the captains of the two surface ships didn't look very good.

With the protection of comrades from the naval aviation, the tops of surface ships are indeed much safer than in the past, but the threat from below has not weakened at all.

They are not afraid of fighting the enemy with all their might.

It's just that this invisible opponent doesn't even have a chance to fight.

When they thought that their warship might even be under the surveillance of the opponent's nuclear submarine throughout the whole process, the two of them felt their scalps go numb.

“The Type 601 and Type 675 sonar equipped on our ship, even in the previous test state, the detection distance for Type 033 submarines is only 6km…”

Although the reality was very cruel, He Hu, the captain of the Jingjiang, could only bite the bullet and report the situation at that time.

"Furthermore, because the Type 22 frigate sent by the other party to confront us is very fast and the speed change is very flexible and agile, in order to ensure that the ship can speed up quickly, our ship has to keep the boiler at a high power level, causing the ship to make noise It's too big. In fact, it doesn't have the conditions to turn on the sonar equipment…”

At the end of the sentence, his voice became much softer.

Because no matter how you sound, it sounds like you are shirking responsibility.

But this is the reality.

This is true for steam turbine ships, not to mention the Rongzhou using a diesel engine.

The noise and vibration of an internal combustion engine traveling at high speed will only become more terrifying.

The leader sitting on the stage naturally saw He Hu's concerns.

“Comrade He Hu, don't have any psychological burden. We are all materialists. The objective situation is the objective situation. Speak out boldly.”

"Report, I spent some time on the North Sea Fleet's destroyer Ice City last year. I think that if we really want to strengthen our anti-submarine capabilities, we must first consider adding a gas turbine in terms of power, so that we can search for submarines at medium and high speeds. capabilities, and the other is aviation anti-submarine capabilities. The search capability of an anti-submarine helicopter is at least equivalent to 2-3 surface ships..."

He Hu was encouraged to express his thoughts.

In a word, it is difficult to make a meal without rice. This high-tech battle still requires new equipment.

Of course, with his position as a captain and a captain, these words can only be said.

Everyone knows that the navy's current desire to build new ships, especially new ships powered by gas turbines, is not a matter of military spending at all, but that after the supply of the LM2500 gas turbine was cut off, it could not even find a reliable power source.

If domestic manufacturers had not urgently conquered the repair and remanufacturing technology of some wearing parts, even the No. 052 No. 2 ship would not have been built.

Because it is necessary to provide spare parts for the No. 1 ship.

However, for Yang Shuyu, this is not the case.

Because there is currently a new frigate project that is at the final stage of program selection.

Two options, one is full diesel power and build a smaller version of 052.

The second is full combustion, or at least diesel-fuel alternating power, which is a completely new thing.

Party B, who is responsible for the design, is unabashedly inclined to recommend the second option. The advantage is that the potential is greater and the localization rate of the power system is higher. The foreign exchange saved can even buy a batch of 27PS anti-submarine cards at a ratio of 3:1. helicopter.

But it is not without risks.

Even the prototype of the domestic gas turbine is still in the manufacturing stage. If the specifications fail to meet the requirements, there will be no substitutes and we will have to completely overturn it and start over.

On the other hand, although the domestic production rate of the Pilstick diesel engine is average, it is something that is immediately available and has been used smoothly, and there will definitely be no mistakes.

And if converted according to the exchange rate, the price is cheaper. Anyone with a discerning eye can see that at the current rate of development, the country's foreign exchange shortage may not last for many years. When such ships are mass-built, there is a high probability that such a strict foreign exchange quota system will not be implemented.

So the navy was still hesitant.

But under today's situation, Yang Shuyu's heart moved a little.

Generally speaking, such a decision related to the overall development of equipment is definitely not decided by one or two people, and a small person like He Hu has no way of exerting any influence.

But if the balance of the game is in the middle, even the weight of a hair can sometimes be enough to change the overall situation.

The other side.

Unsurprisingly, an encrypted letter was delivered to the capital the next day.

According to the requirement of "not reading and handling secrets in unclassified places", Chang Haonan was taken to a conference room of the Commission of Science, Technology and Industry for National Defense.

"I think we can consider setting up a permanent office for you here. If you have military-related matters that are inconvenient to handle at home or school, you can come to us to work."

Huai Guomo, who accompanied Chang Haonan, said in a half-joking tone.

Now that the Ministry of Science and Technology has assigned Chang Haonan an official title as the 973 Project Expert Group, the Science and Technology and Industry Committee must express something as Chang Haonan's "native family".

Although Chang Haonan thinks this opinion is good, he still doesn't feel embarrassed to ask for it.

In fact, he may not be able to come to the Science and Technology Committee twice a month. It is too luxurious to have a separate office.

Besides, it's a bit high-profile.

It doesn't suit his character.

Hai Guo Mo did not force it, anyway, there are many opportunities later.

He just handed the letter to Chang Haonan, and then sat on a sofa in the corner of the conference room.

“Let me go...this British man is indeed dishonest...”

After reading the entire content of the letter, Chang Haonan leaned back on his seat and muttered to himself.

Having said that, there was no anger or solemnity on his face, but a mysterious smile.

Rubbing his swollen forehead, Chang Haonan picked up the paper and pen he had prepared long ago from the conference table and began to think about the wording of the reply.

“What, you figured it out now?”

Huai Guomo on the other side of the room was already prepared to wait for several hours or even half a day, but in the end, he didn't even sit down to warm his buttocks, and he seemed to have settled the matter...

This efficiency is truly astonishing.

“This...of course it can't be something I just started thinking about.”

Since the other party asked such a question, he must know the content of the letter, so Chang Haonan directly gave an explanation:

“This is something I have thought about before at the Institute of Electronics 14.”

Chang Haonan said and began to write:

“Actually, they have made things complicated. In this case, it is obvious that the Harrier that the other party took off brought electronic jamming equipment, and it should be a very old type of simple noise jamming equipment.”

Huai Guomo was born in chemical engineering and didn't know much about electronic information technology, but these basic things were not difficult to understand, so he was stunned when he heard:

“Then isn't the British technology very powerful? Their previous pods were more effective than the electronic warfare aircraft we just put into service, and the Sea Harrier shouldn't have professional electronic warfare modifications, right?”

"That's not the case. Although it is generally believed that noise interference power requires a lot of power and is an imprecise cover interference, as long as the precise signal carrier frequency and bandwidth characteristics of the radar can be obtained, targeted interference can still be carried out. This does not mean that The opponent's technical level is higher than ours.”

Chang Haonan, who was writing furiously, shook his head.

"For normal electronic jamming equipment, this kind of operation requires analysis after intercepting the signal, which requires very high algorithms, especially the current agile frequency radar, which is even more difficult to handle. However, the SouShui 2000MS is originally a British product. They must have a standard answer, so they can skip this most difficult step."

“It's equivalent to the math test steps having been written out, and they just have to calculate the answer at the end. Of course, the results will come out quickly, but it doesn't mean they have the ability to calculate the question from scratch.”

His original intention at the beginning was actually to comfort the somewhat panicked Deputy Director Huai.

But after saying the second half of the sentence, the other party seemed to be even more panicked...
