For the Huaxia Navy in 1997, if the air defense capability is to make up for the sky with Nuwa, then the anti-submarine capability is still waiting for the creation of Pangu -

It's basically equivalent to non-existent.

As for how bad it is......

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

The two warships, the Jingjiang and the Rongzhou, which were dispatched this time, had neither anti-submarine helicopters nor towed sonars, and not only could they only rely on the hull sonar to search for submarines, but even the weapons that could attack submarines were only rocket depth bombs......

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

However, the main role is to carry out testing and technical verification, because the performance of the sonar itself is limited, and the noise of the ship is huge, so the actual submarine search capability is better than nothing, so that in the new century after the refit directly dismantled this set of things.

Not to mention the tormenting service capability of the 051 series ships, the 166 ships are in the maintenance and overhaul period after the last voyage at this time, and they are simply unable to carry out this mission.

After hearing this news, the faces of the captains of the two surface ships were not very good-looking.

With the protection of comrades in naval aviation, the surface ships are indeed much safer than in the past, but the threat from below the ass has not diminished in the slightest.

Fight with the enemy, they are not afraid.

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

The thought that their warship might even be under the surveillance of the other party's nuclear submarine the whole time, the two only felt their scalps tingle.

"The Type 601 and Type 675 sonars equipped with our ship, even in the previous test state, have a detection range of only 6km for Type 033 submarines......"

Despite the cruel reality, He Hu, the captain of the Jingjiang, could only report the situation at that time.

"Moreover, because the Type 22 frigate sent by the other side to confront us is very fast, and the speed change is also very flexible and agile, in order to ensure that the ship can quickly speed up, our ship has to keep the boiler at a high power level, resulting in excessive noise on this ship, and in fact, it does not have the conditions to turn on the sonar equipment at all......"

By the end, his voice had become much quieter.

Because no matter how you listen to it, it seems to be shirking responsibility.

But this is the reality again.

This is true for steam turbine ships, not to mention the Rongzhou, which uses diesel engines.

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

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

"Comrade He Hu, don't have a psychological burden, we are all materialists, the objective situation is the objective situation, speak out boldly."

"Report, I had a period of further study on the destroyer Bingcheng of the North Sea Fleet last year, and I think that if you really want to strengthen your anti-submarine capabilities, you should first consider adding gas turbines in terms of power, so as to obtain the ability to search for submarines at medium and high speeds, and the other is the aviation anti-submarine power, and the search capability of an anti-submarine helicopter is at least equivalent to 2-3 surface ships......"

Encouraging, He Hu spoke his mind.

All in all, it is difficult for a clever woman to cook without rice, and this high-tech combat still requires new equipment.

Of course, with his position as a captain of a colonel, these words are just that.

Everyone knows that now the Navy wants to build new ships, especially new ships powered by gas turbines, which is not a matter of military spending at all, but after the supply of LM2500 gas turbines is cut off, even a reliable power source cannot be found.

If it weren't for the domestic manufacturers who urgently overcame the repair and remanufacturing technology of some wearing parts, then even the No. 2 ship of Type 052 would not have been built.

Because it is necessary to supply spare parts to ship No. 1.

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

Because at the moment there is really a new frigate project that is at the last moment of program selection.

Two schemes, one is full diesel power, to build a reduced version of 052.

The second is full combustion, or at least the alternating power of diesel combustion, completely the whole new thing comes out.

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

But it's not without risk.

The prototype of the domestic gas turbine is still in the manufacturing stage, and if the indicators do not meet the requirements, even a replacement cannot be found, so it can only be completely overturned and restarted.

On the other hand, although the localization rate of the Piertic diesel engine is average, it is a desirable thing that has been used smoothly, and there will be absolutely no mistakes.

And if you convert it at the exchange rate, the price is cheaper.

Anyone with a discerning eye can see that at the current speed of development, the country's shortage of foreign exchange may not last for too many years, and when such ships are built in batches, there is a high probability that such a strict foreign exchange quota system will not be implemented.

So the Navy was still hesitating.

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

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

But when the balance of the game is in the right place, even the weight of a hair is sometimes enough to change the overall situation.

……

The other side.

Not surprisingly, the next day, an encrypted letter was delivered to the capital.

According to the requirement of "not reading secrets in non-confidential 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, and then if you have similar military-related affairs that are inconvenient to deal with at home or school, you can come to work with us."

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

Now the Ministry of Science and Technology has arranged an official title for Chang Haonan as a 973 project expert group, and the Science and Technology Commission has to say something as Chang Haonan's "mother's family".

Although Chang Haonan thought this opinion was good, he was still embarrassed to ask for it.

In fact, he may not be able to come to the Commission of Science and Technology twice a month, and it is too luxurious to have an office alone.

Besides, it's a bit high-profile.

Not in line with his character.

Huai Guomo didn't force it, anyway, there are more opportunities in the future.

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

"I'll ...... This Englishman is really dishonest......"

After reading all the contents of the letter, Chang Haonan leaned back on the back of the seat and muttered to himself.

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

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

"What, this makes sense?"

Huai Guomo, who was on the other side of the room, was already ready to wait for a few hours or even half a day, but he didn't even sit on his buttocks, and he seemed to have already done it......

That's amazing efficiency.

"Is this...... Of course, it can't be something that I just started thinking about. ”

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

"This is something I thought about before at the 14th Institute of Electronics."

Chang Haonan said and began to write:

"In fact, they complicated things, and this situation is obviously that the sea harrier that took off on the other side brought electronic jamming equipment, and it should be a very old, simple noise jamming device."

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

"Isn't that a great skill for the British? Their previous pods worked better than the electronic warfare aircraft that we had just put into service, and the Sea Harrier should not have a professional electronic warfare modification, right? ”

"That's not it, although it is generally believed that the noise interference power demand is very large and belongs to non-accurate masking interference, but as long as the accurate signal carrier frequency and bandwidth characteristics of the radar can be obtained, it can still carry out targeted interference, which does not mean that the other party's technical level is higher than ours."

Chang Haonan, who was struggling to write, shook his head,

"This kind of operation needs to be analyzed after intercepting the signal for normal electronic jamming equipment, and the algorithm requirements are very high, especially the current agile frequency radar is even more difficult to deal with, but the Soshui 2000MS is originally a British thing, and they must have a standard answer, so they can directly save this most difficult step."

"It's equivalent to the math exam steps have been written, and the final answer is calculated, and the result is of course fast, but it doesn't mean that they have the ability to calculate the problem from scratch."

His original intention at the beginning was actually to comfort Deputy Director Huai, who was a little panicked.

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