Chapter 333 Silence

Blue sea, blue sky and rough waves.

The waters near the Nansha Islands in the South China Sea have become lively these days, and many ships have traveled thousands of miles to come here.

As a narrow strip of water, all parties in Southeast Asia have more or less sent observation boats over.

There are also observation ships from other regions in the Pan-Pacific region, as well as the Western Continent Alliance, Lucia, and Tianzhu.

As for the eyes in the sky, there are many of them.

The world's attention is focused on this sea area.

In the stormy sea, a fleet came through the wind and waves, leaving white tracks on the sea. The fluttering flags and the sailors on the deck held their heads high, making the spectators involuntarily stare.

On the Japanese observation boat, in addition to a dozen Japanese people, there were also a dozen white people. Although these white people were all wearing casual clothes, there was an obvious military flavor in their temperament.

Since they were not invited, the Seventh Fleet borrowed Japan's spot for observation.

Lewis held a telescope and carefully looked at the fleet that was slowly sailing by. Although it was not as luxurious as the equipment of the Seventh Fleet, and there was no final aircraft carrier, he looked solemn.

Staff officer Ross on the side put down the telescope in his hand and said in a slightly low tone: "Their strength has increased a lot recently."

As the deputy chief of staff of the Seventh Fleet, Ross has been responsible for the collection and analysis of military intelligence in the Asia-Pacific region. He is the first person to know the intelligence in the Asia-Pacific region and the best understanding of the strength of the fleet in front of him.

In just over two years, the opponent's warships have nearly doubled in size.

If it were just the size of the warships, Ross wouldn't be too worried. After all, the United States accounts for half of the world's warships.

The problem is the technology involved.

Silicon nano-coating increases the strength of the ship's hull, and the part below the waterline is less likely to be parasitized by marine organisms, reducing the ship's underwater friction.

In addition, silicon nano-coating and nano-powder metallurgy technology have also improved the performance of engines, bearings, and propellers.

Many shipyards in China now use silicon nano-coating and nano-powder metallurgy spare parts, which have greatly improved their overall performance.

On the other hand, due to technical blockades, other shipyards around the world do not have this processing technology, or the processing cost is too high.

Among them, China Shipbuilding Industry Corporation, the most luxurious company, purchased steel plates made of nanopowder directly from Tongzhi Iron and Steel Co., Ltd. for shipbuilding.

If foreign shipyards do this, production costs will increase by more than five or six times. The core of powder metallurgy is to have cheap nanopowders, otherwise they can only be used for core parts.

Even the wealthy American shipyards cannot afford to use full nanopowder steel.

This kind of luxurious shipbuilding materials has greatly improved the overall performance of the ships manufactured by China Shipbuilding Industry Corporation. Relying on the advantages of materials, it has widened the distance from other shipyards and has become a new peak in the global shipbuilding industry. .

Ross judged part of CSIC's technological improvements through the civilian ships recently produced by CSIC.

Although civilian ships will not all use luxurious powder steel, the proportion of powder steel used in some core components is very high, reaching about 70 to 80%.

Sighing lightly, Louis said with some distress: "Those guys in China blame each other all day long. They don't know the pressure on our front lines, nor do they know the severe situation in the Asia-Pacific."

"Oh, look, Lewis!" Ross exclaimed, holding a telescope and pointing to the sea in the distance.

Lewis raised the telescope again, searched the sea for a moment, and saw the target that Ross exclaimed.

A huge black submarine suddenly appeared on the sea, its smooth surface densely covered with dark blue "scales".

Ross estimated the size of the snakehead fish, and after a while he came up with an approximate figure: "It's so big, with a displacement of at least 15,000 tons."

"There is no turtle back, which is another expected situation, Fake Squid!" Lewis gritted his teeth.

The appearance of this huge submarine aroused heated discussions among the spectators. Among them, the small groups watching the excitement were not too nervous. After all, if the sky fell, there would naturally be tall people holding it up. It was not their turn to worry about such things. .

The worried forces are those medium and large forces, such as the other four big gangsters who were observing the situation and were staring at the submarine intently.

Although this submarine, which was exposed for the first time, was slightly smaller than the Ohio class by 3,000 tons, Lewis and Ross did not dare to underestimate each other.

Lewis, with a solemn expression, turned to the Japanese respectfully and ordered: "Muto, take a look at the sonar data."

The respectful Muto Changji immediately nodded and bowed: "Hi! I have already given the order."

A few minutes later, a crew member hurried over with a report, handed it to Muto Nagaharu, and whispered a few words in his ear.

Muto Nagaharu's eyes were very complicated, and he immediately put away other thoughts, turned around and respectfully reported: "Mr. Lewis, this is the sonar data that was just compiled."

Taking the document, Lewis frowned and asked after reading it: "Muto, are you sure?"

Muto Nagaharu immediately replied: "Hi! Our ship has VDS (Variable Depth Sonar), so there won't be too much error."

"Wang Defa!" Lewis got a headache.

The reason why he felt a headache was because the sonar detection was unable to detect the existence of this black fish.

You must know that this Japanese observation boat is equipped with the most advanced variable depth sonar. The distance between the two sides is only about 8 kilometers at most. At such a close distance, the other party was not discovered.

It can be seen that the navigation noise of this submarine is basically as low as it can be.

"Lewis, a new discovery, this black fish has never wandered around."

No waves? Lewis raised the telescope again and locked his gaze on the sea surface at the rear of the submarine. Sure enough, there were no obvious waves.

Generally speaking, when the propeller propels the ship forward, due to its own structure and high-speed rotation, it will generate a large number of cavitation bubbles. After these cavitation bubbles explode in the seawater, they will produce obvious noise. If it is on the sea, it will A series of white waves appeared at the tail.

Lewis asked with an ugly face: "What do you think?"

Ross, who was thinking intently, expressed his thoughts after a while: "It may be shaftless pumping or magnetic fluid propulsion. I guess the shaftless pumping may be larger."

"It's so scary. The opponent is sailing right in front of us, but our sonar seems to be deaf." Lewis, who was frightened, looked extremely ugly.

But Ross continued to analyze: "Even if the shaftless pump can reduce navigation noise, why does the active sonar fail? Is it the sound-absorbing material?"

In fact, as Ross speculated.

The surface of this new submarine is covered with a very special sound wave absorbing material, which prevents the sound waves emitted by the active sonar from being reflected back.

It is the application of this material, coupled with the low-noise shaftless pump, and the elimination of the very abrupt turtle back, that completely turns this submarine into a black hole in the ocean.

Facing such a terrifying submarine, no wonder Lewis looked ugly, no one wanted to face such a silent killer.
