Space Base Arms Dealer

When a submarine is sailing underwater or conducting anti-submarine warfare, it mainly relies on the sonar system. The sonar system is divided into active sonar and passive sonar. Active sonar works like a radar, continuously scanning the target.

, to obtain its parameters to determine the orientation. Passive sonar only receives signals from the outside world to determine the surrounding environment and enemy situation.

Under normal circumstances, submarines mainly rely on passive sonar underwater and rarely use active sonar. Because the most important feature of submarines is concealment, if active sonar is used, it will be like a lurking killer jumping out and shining a flashlight on the target.

Again, it's extremely stupid behavior.

Undoubtedly, the detection distance of active sonar is longer, some reaching nearly 100 kilometers, and the data obtained by active sonar is also more reliable, but in most cases, active sonar will not be turned on easily.

In comparison, passive sonar has a shorter detection range and cannot make accurate judgments on many underwater situations, which is why submarines frequently collide.

Just like the two Los Angeles-class nuclear attack submarines in the United States, they are sailing slowly underwater. Without the use of active sonar, no one can even imagine their existence.

However, Fang Shijie's two submarines, relying on the advanced detection equipment on them, easily discovered their existence from fifty kilometers away. Moreover, this discovery was not only vague like the data detected by ordinary sonar, but was very clear.

You can see its rough outline on the screen.

This is the disparity in strength caused by technological generation differences!

The two American submarines are now almost stationary. Their mission is to block all approaching submarines. If a submarine sneaks in, they can easily detect each other due to the noise generated by navigation, but the other party cannot detect the relatively stationary submarine.

they.

Now, however, the situation has completely reversed.

The American submarine lurking at the bottom of the ocean did not notice Fang Shijie's two submarines approaching at high speed, but Fang Shijie's submarine had already caught sight of the two American submarines!

You must know that the United States has more than just these two submarines near the military port. The military port is an important place, and the American people's protective net is definitely more than that.

Within hundreds of nautical miles around the military port, the Americans have also installed hundreds of sonar arrays on the seabed. These dense sonar signal collection devices can monitor all abnormal conditions in the waters, let alone a ship.

It's a submarine. Even a big fish can be detected accurately.

But how could Fang Shijie's two submarines be so simple?

The female goblin is very familiar with the situation on the earth, and she also knows that the concealment of submarines is a guarantee of safety, so the surfaces of these two submarines use an advanced absorbing material that can absorb the energy sent by the sonar device to the greatest extent.

Detect signals, giving them effective stealth capabilities underwater.

The silent performance is extremely outstanding. This ensures that they will not be detected by the enemy's passive sonar; the advanced surface absorption coating can easily avoid the exposure of enemy sonar. This is completely a stealth submarine on the seabed!

This is why the American submarine cannot detect Fang Shijie's submarine, but Fang Shijie's submarine can discover the secrets of the American submarine.

Fang Shijie looked at the two American submarines on the screen and thought to himself: "Let's use you two roadblocks to sacrifice the flag!"

He immediately ordered an attack on the two American submarines: "Four torpedoes are on standby, and we have dual-band attacks. Kill these two enemy submarines for me!"

Soon, the two torpedoes rushed out of the launch tube and rushed towards the two US Los Angeles-class nuclear attack submarines.

As soon as the two torpedoes came out of the launch tube, the two American Los Angeles nuclear attack submarines immediately discovered the situation. After all, the speed of these two torpedoes was very high, they were boosted by rockets, and there was no stealth coating on them.

It is strange that the United States cannot discover it.

The two American attack submarines discovered that they were under attack almost immediately, and they were very surprised. Where did these two torpedoes come from?

This water area is exactly like a small American courtyard. The gate is full of guards. Where did the enemy sneak in?

It was discovered that it was not just the two submarines that were attacked. The sonar array installed by the Americans on the seabed had their main control room on the shore. As soon as these two high-speed torpedoes were launched, the control room on the shore immediately

It was a hectic mess.

"There is an enemy invasion! We seem to have been attacked! Our submarine has been attacked!" The shore-based sonar control room immediately reported the situation to the superiors.

In a very short period of time, the commander of the Seventh Fleet headquarters received news of the enemy's sneak attack.

"What? How did the enemy get in? Are all our precautions just for decoration!" the base commander was furious.

However, what is at hand is not how to figure out how the enemy entered their territory, but how to avoid the two Los Angeles nuclear submarines.

The battle under the sea is actually somewhat similar to the air battle. Facing the incoming torpedo, all the submarine can do is emergency evasion, and at the same time, it releases decoy bombs to attract the torpedo to crash into the false target and explode itself.

The two Los Angeles-class nuclear attack submarines, which had been moving slowly just now, immediately turned on their full power and moved sideways in a hurry, trying to avoid the torpedo attack.

But what frightened the two American submarines was that not only were the two torpedoes extremely fast, far exceeding ordinary torpedoes, they were also very flexible, and their forward direction kept correcting as the American submarine moved.

Trajectory, clinging to the target, rushed over without hesitation.

"No! These two torpedoes are very advanced! They are very fast and have automatic tracking function!" The people on the two American submarines panicked and urgently reported the situation to their superiors.

There was no need for them to report it. The sonar control room on the shore had already discovered this situation, and they all hurriedly reported it.

In fact, in modern warfare, due to the slow speed of torpedoes, they are easier to intercept on the water surface. As long as they are operated properly underwater, submarines can easily avoid torpedo attacks.

However, if it is attacked by a guided torpedo at close range, the submarine being attacked will be unlucky. Their evasive actions will be difficult to achieve and they can only fire decoy bombs.

Guided torpedoes actually mean that after the torpedo is launched, a long control line is dragged behind its buttocks. After launching, the crew can guide the direction of the torpedoes in the submarine and operate them to change directions at will so as not to deviate from the target.

However, the wires guiding torpedoes are generally not too long. If the target is too far away, the missile will be broken in the middle. Whether subsequent attacks can succeed depends on the luck of the torpedo.

But now, the two torpedoes seem to have exceeded the maximum distance of the control wires, but they still seem to be able to change direction independently. This is really scary!

Just as the naval officers and soldiers in the American submarine were panicking, they suddenly discovered that two more torpedoes were attacking!

"Damn it! This torpedo is already difficult enough to deal with, who knew there would be another one!" A submarine captain said in shock and hatred.

However, when Fang Shijie launched his second torpedo attack, the American soldiers on the shore who had already concentrated on finding his location finally determined the approximate locations of Fang Shijie's two submarines.

Even after the Americans encountered a very emergency situation, their combat network was still operating in an orderly manner. While some people were panicking about how to make the two nuclear attack submarines avoid this disaster, others were

Always searching for traces of the enemy.

"They are in area 52! The depth is about 580 meters! The torpedo was launched from there! The detailed coordinates are xx.xx."

At this time, there is no need for an order from the Commander-in-Chief of the Seventh Fleet. The combat center below has already issued the attack order on its own.

"All anti-submarine attack forces take action immediately! Destroy the enemy for me!"

The Americans have very high combat efficiency. Even in a peaceful environment, they can often start combat procedures in the shortest possible time. But I don’t know if these naval units stationed in the Japanese country were changed because of the Japanese attack on Pearl Harbor.

Act so quickly.

Two anti-submarine helicopters in nearby waters immediately rushed to Area 52. The anti-submarine missiles they carried were the biggest natural enemies of submarines.

At the same time, several high-speed fighter jets took off from the airport on the shore, roaring towards the target area.

In the naval port, the American sailors on the battleship who were busy having breakfast also threw down their tableware and ran to their work stations. One by one, the destroyers and frigates pulled anchor and set sail towards the battlefield.

Of course Fang Shijie knew that Americans were not vegetarians, and he would not just stay where he was and let the Americans bomb him.

After launching two rounds of torpedoes, Fang Shijie immediately ordered the submarine to change its course and sail to deeper waters, and ordered the submarine to dive to a depth of 950 meters, which was close to the limit.

"If you want to find out where I am, come find me! Speaking of which, I haven't played a hide-and-seek game for a long time!" Fang Shijie said with a cheerful smile while sitting in the submarine control room.

Just when Yokosu Naval Port was in a state of turmoil, the President of the United States' breakfast was also interrupted by this incident.

"Our submarine was attacked? And it was near the heavily guarded Yokosu Port!" Abama was shocked.

The Minister of Defense said solemnly: "Yes, Mr. President, and so far, it seems that no one has been found who did it."

Obama was worthy of becoming president. He was extremely shocked and immediately thought of who might have done this.

"Is it that damn guy again!?" Abama felt his head hurt again.

The situation is getting worse now!

That mysterious arms dealer not only owns an extremely powerful aircraft carrier, but also four cruisers with extraordinary power. Now, even a submarine has appeared. How many terrifying weapons does he possess?

Now Abama feels a little regretful. Maybe he shouldn't have gone against this arms dealer from the beginning. Now troubles are coming one after another. How should the United States deal with it?

"You just said that the enemy successfully evaded our blockade and broke into the inner defense circle?" Abama wanted to confirm again.

"Yes, Mr. President! The enemy's submarines are very advanced. According to preliminary estimates, there were two submarines involved in the invasion this time," the Defense Minister replied.

Although Obama is not a military professional, as the commander-in-chief of the three armed forces, it is impossible to say that he does not understand military aspects at all.

The underwater area within hundreds of nautical miles around Yokosu Military Port is almost covered with the U.S. sonar detection network. If the enemy's submarine can successfully break through this dense line of defense, what does that mean?

This can only mean that two more fearsome underwater monsters have appeared!

This arms dealer not only possesses powerful sea and air control weapons, but also possesses more advanced submarines, which has almost completely overturned the status of the United States as a military power.

Now, apart from nuclear weapons and space weapons, the United States has almost nothing to offer on the ground.

Abama suddenly felt a sense of sadness. Is the United States going to decline in his hands? The reason for this is not that the Americans experienced unexpected natural disasters, nor were they attacked by major powers, nor were they disintegrated from within...

The culprit of this situation turned out to be just an arms dealer! A small arms dealer actually made the United States, the number one power, appear to be in danger of losing its status. This made Obama very sad.

"I hope our two submarines will be safe and sound!" In the end, Abama could only resign himself to his fate.

In the depths of the ocean far away from Yokosu Military Port, the two American nuclear attack submarines finally reached the most critical moment. They fled separately, turning left and right from time to time, trying every means possible to get rid of the tracking of the four torpedoes.

However, no matter what maneuvers the two submarines made, the four torpedoes behind them still bit their butts tightly, as if they would not give up until they were destroyed.

"Come up as fast as possible!" the captain of one of the submarines suddenly shouted an order.

If it really cannot avoid a torpedo attack and the submarine is hit in shallow water, the chances of the crew inside escaping are relatively high. If it is hit in deep water, it can be said that the crew members have almost no way to survive.

Although submarines have relevant escape equipment and escape passages, and these facilities have fully taken into account the situation of distress in deep water areas, until now, after a submarine is in distress in deep water areas, almost no crew members inside can escape alive.

came out.

The captain had no hope of escaping the torpedo attack at this time.

Senior officers at the shore command were also aware of this situation, and in order to reduce losses, they also ordered another submarine to implement emergency self-rescue measures.

"The enemy torpedoes are too fast! Several times faster than ordinary torpedoes! And they can automatically track like missiles. Our submarines have no way to avoid them!" Whether it is the Americans in the submarine or the Americans on the shore, they are right.

This kind of torpedo is advanced and

Surprised. Of course, they are more sad because they are the ones being attacked. (To be continued. If you like this work, you are welcome to come to Qidian.com to vote for recommendations and monthly votes. Your support is my greatest
