Almost simultaneously, the three submarines activated the silent mode.

Under this mode, the power of the submarine will be reduced by 145%, and the power required for propulsion will be completely borne by the propulsion system composed of fuel cells and rare earth permanent magnet motor locks.

Under this mode, the three submarines will change from hungry tigers to hidden dragons, cruising almost silently at a depth of 100 meters under the sea.

Although the previous test has given Xing Yaxin absolute confidence in going to sea this time, because he does not know what the bottom line of the anti-submarine sonar system deployed by the United States in the international waters of South China Sea is, Xing Yaxin is still nervous at this time.

In fact, it's not just Xing Yaxin who is worried. All the officers and men on the three submarines were already holding their breath at this time. Even the operator's movements involuntarily stiffened slowly.

The incident two months ago was too hard for them.

Once bitten by a snake for ten years and afraid of the well rope, from the moment he walked out of the sea boundary, the three submarines were already pin dropping, and the birds were silent!

In silent mode, all unnecessary electronic devices and devices that can make noise are turned off.

So inside the submarine, there are only a few red ghost lights left.

In this silence, even the friction sound of the outer side of the submarine cutting through the sea water seems to be clearly audible.

Li Fan swallowed his saliva involuntarily - and then he regretted it.

That grunt, which usually doesn't attract people's attention at all, looks so huge in the submarine at this time!

"Don't be nervous,"

Looking at Li Fanyu's appearance, Xing Yaxin lowered his voice and said softly.

"Report the situation. After that, he asked the submarine commander.

"No active sonar found,"

"Dive according to the established route and be silent. ”

"Yes,"

Even the order was silent, as if these sixty people, together with the submarine, had turned into a rock on the bottom of the sea, a piece of seaweed.

………

McHaus was speaking to CNN reporters about the progress of the grand exercise to the whole of the United States and the politicians in front of the live screens.

With his continuous scheduling, the entire military exercise process was carried out in an orderly manner, and various high-tech war techniques were put into battle in turn, and under the continuous power of iron-blooded weapons, he looked quite heroic in reprimanding Fang Xuan.

In the West, it's called charisma. In the East, perhaps it should be described as a Confucian general.

The head of CNN has a close relationship with McHouse, and the reporter who was broadcasting at the front has already communicated with McHouse in advance.

Because it is necessary to show his face in front of the people of the whole country and the president and vice president, some outstanding questions have been told by the reporter in advance.

"General, according to the normal configuration of the aircraft carrier battle group, submarines must accompany them to ensure underwater safety, right? However, in the establishment of the combined fleet this time, it seems that there are no submarines accompanying them. Maybe I didn't notice?"

Inside the flagship, the reporter asked McHaus.

McHaus raised an eyebrow quietly and began your own performance: "No, no, no, sir." You read that right, there are no submarines in our fleet. ”

"Why?" Before the reporter could ask, the president over there had already spoken.

Seeing that the success had caught the president's attention, McHaus smiled slightly and explained, "Because of our underwater sonar detection system." With the presence of this system, the movement of enemy submarines is clear to us at a glance. If the enemy uses submarines in the middle of a conflict, we will destroy them as soon as possible. And as we all know, it is difficult for submarines to keep pace with the fleet because of the problem of the channel, so the formation with submarines will be insufficient in terms of reaction speed. Now that we have an all-round defense network, there is little need for submarines to exist in the fleet. ”

The underwater sonar system has been the main work of McHaus in the past six months, so it must be well publicized at this time.

Seeing that the president held his mouth and did not make the reaction he imagined, McHaus hurriedly struck while the iron was hot, "Our sonar system has achieved good confirmation. Two months ago, we successfully captured three Chinese submarines and used anti-submarine drones to locate them within half an hour. It has been learned that those three submarines are the most technologically advanced submarines currently deployed by the Chinese South China Sea Fleet. But such a submarine has nothing to hide in front of our underwater active sonar network!"

"Hmm!"

Listening to McHouse's explanation, the president and vice president were satisfied.

………

"Report! Sonar has detected a large number of surface ships ahead!"

Inside the 079 boat, the inspector put down the headset, couldn't suppress his excitement, and said in a low voice.

"How much?" asked Captain Wang Chunlei immediately.

"At present, 12 large surface vessels have been detected! They are more than 8 nautical miles away from our boats! The preliminary inference is that they are the US maritime exercise fleet!"

"Good! great!"

Wang Chunlei couldn't suppress the excitement in his heart, and hammered his head hard.

The fleet was found in front, which means that the 079 boat has entered the detection range of the other party, but it is at such a distance that the 019 boat is still not detected - this means that the opponent's underwater sonar system, as well as the Aegis defense system carried on the frigates and cruisers of the US fleet, have no ability to detect the 079 boat!

This means that after more than a month and costing more than a billion yuan, the submarine noise reduction project has been a great success!

Xing Yaxin's face was also full of excitement, he clenched his fists and waved it vigorously.

"The purpose of the test has been achieved, chief, will we return now?" Wang Chunlei asked Xing Yaxin with his eyes rested.

"Return?" Xing Yaxin snorted, "Since we are transparent and the information on both sides is not equal, then the time has come to repay grievances and revenge!

"Yes!" Wang Chunlei smiled and waved his hand to the non-commissioned officer operating the submarine, "Carry out the chief's order!"

"Yes!" the non-commissioned officer grinned evilly and adjusted the rudder slightly.

……

Inside the command compartment of the flagship USS Thomas Gates CG-51.

"Report, unidentified underwater objects were spotted ahead. Approaching us. ”

A lieutenant in charge of the inspection took off his headset and said aloud.

"Oh?"

Margayer, the combat analyst of the Thomas Gates, hurriedly walked up nervously and leaned his face closer to the sonar display panel.

He let out a long breath when he saw a small dot on it, intermittently, and then on the sonar display data.

"The reflection data shows that it's 30 decibels, I'm afraid it's not a whale or something. Leave it alone. If the Chinese submarine had appeared in this area, our underwater sonar system would have already alarmed the police. You know, our sonar system can distinguish all mechanical noises above 60 decibels. ”

"But the movement of this point is very suspicious," said the lieutenant, puzzled.

"Haha, Thor, you're too nervous. Look, this is a 30-decibel underwater target, 30-decibels, have you ever seen a submarine that doesn't turn off the flame and has such low noise suppression in the moving state?"

"Uh......" Lieutenant hesitated, "No, sir. ”

Magyar smiled slightly, "So relax, Lieutenant." ”

"Yes, sir!" Thor nodded, and returned to his seat. Seeing that on the sonar panel, the bright spot that seemed to be there just now had completely disappeared, Thor shook his head.

"Looks like I'm going to have some fun after the drill. ”

He thought so.

………

"General, I am proud of what you have accomplished in the Western Pacific! God bless America!"

In the flagship's operational command room, the president and vice president were deeply satisfied after listening to all of McHouse's layout of the South China Sea.

Especially after Bench McHaus showed everyone the scene of the three Chinese submarines "fleeing in embarrassment" captured by anti-submarine drones two months ago.

With such a defensive network, coupled with the strong maritime attack capability demonstrated by the military exercise at this time, the situation in the South China Sea is very reassuring to the two presidents.

A blush had already risen on McHouse's face at this time, and seeing the reaction of the two presidents and the Ministry of Defense, he knew that his promotion was a sure deal!

He had already taken the victory cigar he had prepared in advance in his hand, ready to enjoy the wonderful moment after a moment of communication.

"God bless America!"

Just as he said this sentence with joy, the Thomas Gates suddenly made a big tilt!

This was obviously caused by the warship's sudden and large-angle turn.

This time, Maihaus, who was saluting the screen, directly shrugged his head!

"What's going on!" asked Maihaus, scrambling up from the ground.

"Report to the general, there are submarines!"

A correspondent replied loudly and panting, leaning on the table.

Hearing the news, McHaus, the CNN reporter, the captain of the USS Thomas Gates, and the president and vice president who had not interrupted the communication on the big screen, as well as everyone who was watching the live broadcast of the military exercise, were stunned.

"What submarine?" said McHaus, a question mark on his face.

"Medium...... China's submarine is 0.7 nautical miles from the T side of our aircraft carrier!"

Click,

Hearing this, the cigar in Maihaus's hand fell to the ground.
