Chapter 506: Guided Torpedo

Johnny Johnson is a sonar monitor in the US military fleet. For this job, it is usually a place where absolutely quiet is needed, because sonars can only distinguish different signals in the ocean based on their own hearing.

However, this job seemed to be a torture for Johnny during this period. Because the fleet is too large, the noise generated by various engines and propellers is simply unbearable. But Johnny still needs to continue wearing heavy headphones, because although the passive sonar is difficult to play a role, the active sonar on the destroyer still needs his monitoring to complete the underwater alert search mission.

Johnny has been in this noise and harsh working environment for more than half a month. He is suffering physically and mentally, and now he can't take much energy to continue completing his work. Moreover, the first mate once told him that there have been no ships other than the US military in this sea area, so why should he do?

Looking at the time, I had to switch shifts with others in half an hour to end the torture of a few hours, Johnny's heart was filled with joy.

Suddenly, a slight and dull "dong" sound came from the headphones. The sound made by this active sonar quickly hit Johnny's eardrum under the water with the propagation speed of 1,500 meters per second in the water.

And more than this sound, then there was a continuous thud of thuds coming from the headphones, beating Johnny's eardrums like a drumstick.

"Discover unknown submarine!! Direction 330!" Johnny, who was still silent in a good mood just now, was caught off guard by the harsh sound.

Fortunately, Johnny made an early warning at the first time, and the US fleet immediately made adjustments. Three anti-submarine ships were immediately divided into the escorted ships to expel and annihilate them. The fleet was not affected and continued to move forward in its original course.

There is no way, the fleet is too large to quickly adjust the overall course as a small fleet. Once the fleet needs to change its course, the fleet's commander needs to make a notice in advance to avoid chaos and causing unnecessary collisions when the entire fleet turns.

When there were still a few thousand meters away, he took the initiative to send out his sonar and exposed his figure. This was the first time that such a stupid submarine captain had seen such a stupid submarine. Many US ships were relieved after panic. At such a long distance, when it approached the fleet and reached its range, the anti-submarine ship that went to intercept had already sent it to the seabed!

The anti-submarine ships that were going to intercept were afraid of the unknown submarine that issued active sonar detection. They did not change their direction after being exposed, but continued to head and rush towards the US fleet with a constant speed of thirty-eight knots.

"What kind of damn submarine is this? It's faster than a surface aircraft carrier!" The three US ships in charge of intercepting missed the best area to intercept and cursed. If it were traditional submarines, they could easily run to the front of each other and throw deep-water bombs, leisurely admiring the splashing white water splashes on the water.

But this time it was different. The other party actually broke through his encirclement with a terrible speed. Before he could drop the deep water bomb, the other party had already passed by himself and pulled the fine white blister marks to continue to sail towards the fleet.

"Report, this is not a submarine! This is a torpedo! It is two torpedoes! It is two torpedoes that can make sonar sounds!" On the anti-submarine ship that came to intercept, the noise heard by the passive sonar has dropped to a certain level since it has left the large fleet at a certain distance.

At this time, Johnny, who had been monitoring the movements underwater, then he cried and found that the two active sonar noise sources were not conventional submarines, but clearly heard the noise from the torpedo propeller's rapid and fine rotation and stirring the sea water from the passive sonar.

"You're sure!" The captain couldn't believe his ears, his eyes staring at Johnny with great force.

"That's right! I dare to swear in the reputation of my dead grandfather, this is absolutely true!" Johnny dared to swear that if he heard not the tail sound of the torpedo, he would be willing to let someone put himself in the main guns of the battleships of the fleet as shells. Looking at Johnny's mourning and unbelievable expression, the captain was stunned.

"God! Can the Chinese put huge sonar detection equipment in the torpedo? But even if it is put in, what's the use? Can these torpedoes be searched and attacked surface ships by themselves, just like the German magnetic guided torpedoes?" The destroyer captain looked at the traces of the torpedoes outside Johnny and the porthole, and made a terrible speculation incredibly.

The destroyer captain speculated that the two torpedoes appeared in front of the US Navy were the two active sonar-guided torpedoes used to lure the enemy. These two torpedoes successfully attracted the attention of the US military's underwater monitoring.

In this era when sonar was just developed, the detection distance, accuracy and anti-interference background sound ability of sonar were very weak. What's even more terrifying is that these Americans did not know that the Chinese already had advanced sonar that they could not imagine.

Although the active detection sound emitted by the two torpedoes is not high, the closer they get to the main body of the US fleet, the faster the frequency of the sonar detection waves. The echoes of sonar taps made the US sonar monitors' hearts shatter.

These two torpedoes have a high depth and fast speed, making it extremely difficult to intercept seas with traditional deep-water bombs and ship artillery. In the face of these two sudden mysterious killing weapons, the ships of the main fleet of the US military began to appear in a trace of chaos.

No one knows who the target of these two torpedoes is, and no one wants to make themselves victims of these two torpedoes. It can be said that these two torpedoes not only broke through the escort line of defense on the periphery of the US military, but also broke through the psychological line of defense of human beings, causing artificial chaos in the US fleet.

Entering the last 1,500-meter distance, the two torpedoes began to part ways, and at this time the targets of the two torpedoes gradually appeared. They were two bulk cargo ships sailing in front, with an 8,000-ton body and a 12,000-ton physique that was enough to make these two valuable new torpedoes worth the money.

Unlike the original magnetic torpedo that is mostly close to or explodes after hitting the hull, this sonar-guided torpedo drills into three meters below the bottom of the hull. The navigation system inside the torpedo instantly releases current to the detonating device when it determines that it reaches the target. The precise and accurate detonating object instantly ignites the explosive temper of 260 kilograms of high explosion**.

The powerful chemical kinetic energy pushes away all the sea water around the torpedo, and the huge kinetic energy throws the hull on the top high into the sky. When the kinetic energy on the liftoff cannot continue to fly upward due to gravity offset, the higher the flight, the more painful it will fall, the better it will be reflected in the two ships.

With its huge weight and the acceleration given by gravity, the two ships fell heavily on the sea surface. The economic requirements of the construction of civilian cargo ships destined that the strength of their skeleton could not withstand such torture. The hulls and keel skeletons of the two cargo ships had large areas of cracks under such a fierce impact, and the hull also deformed under such impact.

So far, in addition to these self-guided torpedoes from China, most of the torpedoes in countries around the world are traditional direct flight torpedoes and hit trigger torpedoes.

Although hitting the trigger torpedo can cause certain loopholes and damage to the hull, if the hull is strong enough and has good sink resistance, the effect of this intuitive destructive attack will be greatly reduced.

In addition to the old direct flight torpedo, Chinese torpedoes often use soft-killing attacks that underwater explosion of the hull produces stress damage to the hull, in order to further expand the degree of damage to the hull. Don’t underestimate this soft-killing. If the hull is not strong enough, it will be a catastrophe for the ship being hit.

The 8,000-ton bulk cargo ship is a best example. Three large cracks were thrown out of the entire hull, and sea water surged into the hull. Faced with such a large area and multiple cabins, 80% of the watertight cabins leaked. Even when God came, he could only sigh.

The other 12,000-ton bulk cargo ship is fine. Its body is large enough, and the power of the torpedo at the bottom does not make it fly high. If it doesn't fly high, it means that the fall will not hurt too much.

But despite this, the freighter still produced a crack in the middle of the hull of five centimeters wide and more than 30 meters long horizontally.

With the outstanding performance of other watertight cabins, the cargo ship withstood the overload caused by the surging seawater did not sink directly, but the hull was seriously damaged, the water inlet in the boiler room lost power, and the hull structure was fatal. Even if it was still powered, the ship speed was reduced to a terrible low speed.

The serious injury that broke the spine and caused the ship to lose its practical value in the future. No one was willing to sail on a dangerous ship that could fall apart at any time. After the sneak attack of the No. 098 submarine, the US military sent people to evacuate the remaining crew members on the ship and finally sent them to end their life of drifting at sea.

These two cargo ships were just an appetizing snack for the No. 098 feast on the sea. After launching the first two sonar-actively guided torpedoes, the No. 098 submarine sneaked all the way, following the edge of the other party's sonar reconnaissance and sneaking all the way to another direction.

As the two cargo ships in front were hit by torpedoes, the fleet's route was disturbed, and the ships behind inevitably had some chaos. Although they were not so chaotic that they could kill each other like each other, the fleet's formation and speed inevitably deviated, which gave the submarine No. 098 a better attack opportunity.

Pulling the periscope, Chen Tao, as the captain, happily watched the little chaos that was passionately staged on the sea. Chen Tao saw the fate of the two cargo ships and was happy in his heart.

"If there is more charge and the explosion is more powerful, this torpedo is a magical tool that is against the sky!" Chen Tao quickly let out the observation port of the periscope, and the first mate quickly took the periscope and said with regret.

The navigation performance of these two torpedoes before breaking and automatically finding targets made him quite satisfied, but the power was slightly inferior, and it was so few dozen kilograms less than the first-generation magnetic guided torpedo charge.

"Stay it, it is normal to reduce such a large active sonar system to a torpedo guide head, and also have automatic judgment and control systems. It is normal to reduce the size of the warhead. Wait, when electronic technology continues to develop in the future, electronic equipment will become smaller and more precise, and increasing the loading of its warhead will not be a dream."

The last thing to enjoy the beautiful scenery on the water was the weapon. His focus was on the performance of the two cargo ships being hit, so that he could have enough understanding of the judgment report on the first experiment using this sonar-guided torpedo.

"How many torpedoes do we have?" Chen Tao asked his weapon to quickly descend down from the periscope and began to prepare for a new round of attacks.

"The two torpedo tubes launched on the bow of the ship are continuing to be loaded, and there are still two and a half minutes to be loaded, but there is only one sonar-guided torpedo, and the other five torpedoes are the first generation magnetic guided torpedoes. Among the two torpedoes waiting to be launched behind the stern, one magnetic guided torpedo and the last sonar-guided torpedo."

The weapons quickly reported that there were on standby combat torpedoes, because in the second round of attacks, it was up to see how these torpedoes created terrible results.

"Six magnetic and two sonars, very good! The first round will launch the torpedo at the bow every five seconds. Time does not allow the target to be calibrated twice. Everyone is a veteran of the old hands. Whether they can achieve the greatest results in this attack depends on everyone's performance." Chen Tao stuck out his tongue and licked his lips that were a little dry due to tension. In the eyes of other crew members, this action was more like a greedy demon ready to stretch out his claws.

"I understand, captain, just give orders!" The simple and low answer was filled with the crew's deep self-confidence.

"Very good, refloat to the depth of the periscope, one-third of the speed, periscope, and torpedo compartment report preparations at any time, all compartments are closed, all personnel in the power compartment should be careful, wear gas masks, and use fuel cells!"

In this way, when the US military was under unknown attacks, some minor chaos occurred, in the middle of their fleet, a Chinese submarine was quietly extending its claws to the chaotic flock ahead.

"The position is three, four or eight, and the target is a troop transport ship of at least 16,000 tons, and the No. 1 torpedo is launched!"

"Azip 3, 48, No. 1 torpedo is launched!" A sound and vibration of compressed air pushing out the torpedo, and the No. 1 torpedo was launched under the rapid calibration of the experienced veteran sailor No. 098.

"The torpedo launch hits the timing!" The first mate pressed the stopwatch in his hand, and the ticking sound of the stopwatch was as powerful as the heartbeat of the crew members.

"The target is 355, the target is 12,000-ton bulk cargo ship. The No. 2 torpedo launches!"

"The position 355, the No. 2 torpedo launches!"

"The target is zero or two, the target is 25,000-ton cruise ship, the No. 3 and No. 4 torpedo launches!!"

"Azip zero-zero-two, No. 3 torpedo launches, No. 4 torpedo launches!!" Every five seconds, a torpedo launched continuously attacked from the bow torpedo tube of the submarine No. 076.

"The position is zero one and two, the target is 15,000-ton tanker, and the No. 5 torpedo launches!"

"Azip 012, No. 5 torpedo launches!"

"Sonar-guided torpedo launch!"

"Captain, the No. 6 Torpedo has not determined its target!!" The weapon organ in the torpedo compartment immediately reminded Chen Tao of the order of steps before launching.

"I know that I have not determined the target, the direction is zero or zero, and the launch is instantly. Let's see if I bump into that unlucky guy and make him unlucky!"

"I understand, the direction is zero and zero, launch immediately!" The weapon kissed the No. 6 torpedo tube and then took a photo of the launch. After the last dull launch sound of the bow of the ship, only six empty torpedo tubes and the remaining torpedo cabins were left.

"All people pay attention, the right rudder is full, and the tail torpedo compartment is on the way!"

"The tail torpedo compartment is on standby at any time!" An excited voice came from the speakers inside the submarine. It seemed that the soldiers could no longer contain their excitement and were eager to try.

Taking advantage of the time when the submarine turned around, Chen Tao carefully checked the other party's escort ship. The launch of torpedoes was a huge noise. If the other party was willing, it would not be difficult to lock himself in for such a long time.

Sure enough, the other party obviously heard the noise of his torpedo launch, and the three destroyers and frigates quickly drove towards him in a fierce direction.

"Please note the tail torpedo compartment, position 200, No. 7 magnetic guided torpedo, launch!"

"Azip 200, No. 7 magnetic guided torpedo, launch!"

"Azip 185, No. 8 sonar-guided torpedo, launch!"

"Azip 185, No. 8 sonar-guided torpedo, launch!"

The last torpedo was launched in the vibration. Now the No. 098 submarine is temporarily trapped in a reloaded state without bullets. At this time, the No. 098 submarine has no counterattack ability and can only allow the opponent to attack wantonly and cannot fight back. However, the lack of counterattack ability does not mean that it does not have the ability to escape.

"Down from the periscope, continue to move forward at full speed, return to zero in the rudder, inject water from the bow balanced water tank, the horizontal rudder dives 35 degrees, dive to a depth of 160 meters! Brothers, the wind is tight!"

Chen Tao's joke about bandits did not dampen the enthusiasm of the sailors. It was the king to advance and retreat to preserve themselves. Although the three surface ships that came to attack them were aggressive, this did not make the battle-hardened sailors No. 098 feel any panic.

"The first torpedo hit ten seconds countdown!" When the stopwatch in the first time scale in his hand reached the first time scale, everyone was no longer worried about how they would run away later, but instead pricked up their ears and listened to the exciting explosion roar that they would hear later.

"Ten, nine, eight, seven, six, five, four, three, two, one... hit!" It was like cooperating with the performance of the first mate, and as soon as the first mate finished speaking, a dull explosion came from a distance.

"The first hit!" The sonar clearly heard the familiar and comfortable explosion from the passive sonar. Although I could hear a lot of this sound, I would never get tired of it!

The same mood as the sonar, the sailors No. 098 were also excited. This voice was the best encouragement and stimulation for them.

"The second hit!" Hearing the confirmation of sonar, the sailors became more and more excited, and the adrenaline was constantly secreting and stimulating the human body.

"The third hit!" "The fourth, the fifth hit!" As sonar continues to report results, the sailors are now calm, because everyone knows that the last three are the most critical.

"The sixth one..." The sonar failed to report the sixth one, which made everyone's hearts raise.

"Hit!" The sonar waited for more than ten seconds, and it attracted everyone's appetite. Only then did he confirm that the sonar-guided torpedo hit a bad guy accurately.

"Long live!"

With the sound of sonar's departure, the atmosphere of the submarine 098 sailors reached a peak.
