Luyere's exaggerated movements and surprised words made the Chinese escorts who followed him a little stunned, but before they could react to what was going on, Luyere suddenly turned around and looked at the cadre of the Military Commission who had been accompanying him:

"I'm sorry, but I take the liberty of asking, dear Chinese friend, can I take a tour of the cabin of this ship? Of course, on your part, to be honest, I'm really curious how you managed to make this ship so quiet and stable. ”

The cadre of the Military Commission was stunned for a moment, and then immediately communicated with the leader of G City, and then nodded: "No problem, please here, Mr. Luyère!"

……

Pleasure boats, engine rooms.

Huang Jianguo and Peng Jun took the acoustic wave detector they got from a university in City G and pointed it at one of the noise-reducing shells. A low hum resounded in the cabin as the engine continued to turn, and the wave-shaped needle on the acoustic detector manufactured by the Soviet Instrument Factory in the late fifties was rising and falling on a graphic piece of paper.

Huang Jianguo and Peng Jun, who had always been staring at the shape above, glanced at each other, and both saw irrepressible surprise in each other's eyes.

108 decibels.

This is the average result of continuous measurements over an hour.

In fact, they don't need professional equipment to measure, when the two 240 horsepower low-speed diesel engines are started, the two old engines with nearly ten years of experience in the engine know how much effort this cruise ship has put into noise and shock reduction.

You must know that even ordinary warships will be accompanied by strong vibrations when they start, and the vibrations will not weaken until they run smoothly, but they will still maintain a considerable frequency.

It's still slightly better diesel-powered, and if you run into a boiler-propelled steam turbine vessel, the noise and vibration will be even greater.

Therefore, the hearing of dry turbines is not very good in these years, without him, due to occupational diseases.

Huang Jianguo and Peng Jun are the same, otherwise the two of them talk like roaring, just because they are afraid that others will not hear it like themselves, but after the two engines in front of them started, the two of them were stunned to find that they didn't need to roar when they spoke to each other, and the normal communication was no problem at all.

What's even more rare is that the two engines run very smoothly and powerfully, and more than an hour has passed when they open their eyes, and there is no engine overheating problem that they are worried about.

This made the two of them shocked, but also thinking about how the powertrain in front of them was done?

"108 decibels, let's not talk about this value, just the feelings on this ship know that people are indeed better than our two soil experts in this regard. ”

I don't know how long it took, Huang Jianguo turned off the switch of the sonic tester, picked up the waveform paper on it and looked at it carefully, and finally exhaled a long breath, and handed the paper to Peng Jun on the side: "Old Peng, you have been on the big ship, have you done a similar test?"

The big ship Huang Jianguo mentioned is not the giant ship of more than 5,000 tons in later generations, but the 1,000-ton frigates of the N fleet.

Peng Jun shook his head: "I have been in both the 501 and 503 ships, and the noise of the whole ship has been tested, but I have never seen this kind of noise test of individual parts."

However, you also know that things from special periods are good to be made, and as for the results of the test, it is almost like going through the motions, otherwise how could it be used by Soviet submarines as a target for a simulated attack, and it was teased for nearly three hours!"

When Huang Jianguo heard this, a pair of heavy brows unconsciously erected, and his teeth were even more clenched, what Peng Jun said was the sea confrontation incident at the end of last year, and Huang Jianguo, who was the chief engineer of the 504 ship at that time, was a witness to the incident.

Ever since Dong Yimin, chief of staff of the N Fleet, put forward the request for strengthening the defense of islands and reefs in the South China Sea at a meeting of naval cadres, the Navy Headquarters and the central leadership have attached great importance to it and instructed the N Fleet to make specific plans for the construction of defense posts on islands and reefs, and to arrange for officers and men to be stationed in a timely manner.

In order to implement the spirit of the instructions of the Navy Headquarters and the Central Committee, the N Fleet entrusted Chief of Staff Dong Yi Minh to be specifically responsible for the implementation, and in view of the frequent actions of the Vietnamese Navy recently, in order to effectively complete the transportation of construction materials and the safety of construction at the outpost, Dong Yi Minh dispatched the No. 504 frigate and an oil and water supply ship to form a transport fleet and go to a certain island and reef in the Xisha Islands.

When I went, it was nothing, but when I came back, I was targeted by the Soviet Viktor-class nuclear submarine K-314 cruising in the South China Sea, so I used its strong concealment to follow the 504 ship for nearly three hours, during which it also carried out many simulated attacks on the 504 ship.

The 504 ship was unaware of this, and if it were not for the trawler of the distant-water fishery production team sailing here, it was inadvertently used to entangle the K-314 submarine with fishing nets, and it had to increase its horsepower to get rid of the entanglement of the fishing nets, so that the sonar operators on the 504 ships were aware of it, and then they hurriedly carried out anti-submarine evasion actions.

As soon as the Soviet submarine saw that it had been exposed, it simply raised the periscope and snorkel from under the water, and just swaggered away under the noses of the Chinese officers and men.

Huang Jianguo, who was on the 504 ship at the time, saw this scene, and wanted to jump directly into the sea to pull out the Soviet submarine, but there was no way, it was really the Soviet submarine's actions that were too humiliating, just like the players on the court giving the middle finger to the other party, it was definitely a slap in the face of Chi Guoguo.

And in fact, this is true, because the Soviet Union launched six simulated attacks on the 504 ship formation during nearly three hours of tailgating and tracking, and it was not detected, in other words, the Soviet submarine could destroy the Chinese fleet six times without being aware of it.

In the face of almost crushing superiority, the arrogance of the Soviets can be imagined.

Of course, all of this was reported to China by the US Navy intelligence through secret channels after the fact, otherwise China would not have known that its fleet was under a simulated attack on the way back.

As soon as the news came out, N Fleet said that it was impossible not to be indignant, and the internal war petition flew to the desk of the fleet leader like snowflakes, but unfortunately all of them were pressed by several fleet leaders.

It's not that they don't want to fight the provocative Soviets a few times, but the problem is that if all the capital ships of the N fleet are added together, it is estimated that they will not be able to deal with a nuclear submarine.

If the army is better, and the weapons and equipment are not as good as others, we can use the number of soldiers to make up for it, but the navy is a technology-intensive service, even if you have more personnel, if the equipment can't go up, you can only be pressed to the ground and rubbed hard.

The sorrow of the Navy is here, after all, no matter how elite the strong man with a scythe is, he can't beat the scoundrel with an AK in his hand, which is the reality gap brought about by the technological gap.
