Ten thousand I am across the heavens

Chapter 480 Naruto Navy
The navy already exists in the world of Naruto, and it will develop to a relatively advanced level in the future, and the existence of aircraft carriers will be developed. However, in the world of Naruto now, there is no relatively powerful naval force.

The reason is that ships are too fragile in the water and are easily damaged by ninjas. Facing ships, ninjas can dive underwater and use ninjutsu to destroy ships, and defending against such damage is far more difficult than destroying itself many.

This makes it very cost-effective to manufacture large ships in the ocean. Ninjas can completely use frogman tactics to easily destroy a large number of warships in the ocean with small gains.

If this problem cannot be solved, it will be difficult for Naruto to have a large-scale navy.

Akatsuki is also aware of this problem, and the idea to solve this problem is to enhance the ability to detect the bottom of the water and enhance the accuracy of the sonar carried by the fleet during the detection process.

In this way, once someone approaches from underwater, the difficulty of discovery will be greatly reduced, so there will be room for interception.

Torpedoes can be intercepted, not to mention ninjas who advance underwater. Ninjas may be very good at swimming underwater, and even transform themselves into a shark-like form, with extremely high speed underwater.

But compared with the torpedo that utilizes the supercavitation effect, the speed is much worse. It is not of the same order of magnitude at all, and it is not possible to make up for the gap by changing the body structure and speeding up the swimming speed.

As long as the enemy can be found, whether it is torpedoes or depth charges, there is always a way to intercept it, especially the shock wave of the explosion, which is faster and more powerful in water than in air. If it is hit, it will cause damage. For more serious injuries, it is difficult for ordinary ninjas to bear this level of damage.

Jonin may be able to withstand the shock wave of the explosion and continue to complete the task of destroying the ship, but to that extent, the ninja also needs to consider the cost on his side.

Is it worthwhile to exchange a Jonin for a warship of the opponent?To a country, Jonin is no less precious than the top fighter jets. If they implement the frogman tactic, the cost-effectiveness of this tactic will drop sharply and lose its strategic significance.

It was the maturity of radar technology and sonar technology that made Akatsuki determined to build his own navy. Although there is no sea outlet on the mainland, there is an outlet to the sea in the south of the neighboring country of Sichuan. As his firm ally, he borrowed the other party's port to There is absolutely no problem in building your own navy.

For a long time, the navy has been hidden in the snow and did not participate in the war. The ninjas of the major countries have actually discovered the fleets in the sea, but no one cares.

From their point of view, Xiao is purely a waste of money, what's the use of throwing so much high-quality steel into the sea?Any ninja who touches their boat can sink them.

It was with this mentality that the ninjas of the Land of Fire did not panic when they saw the huge fleet approaching the coastline, but instead showed a sneer of disdain.

"It's such a waste of money to invest so much money in building such a monster without understanding what kind of existence a ninja is. I'm a little bit reluctant to blow up such a beautiful model to the bottom of the sea." Jōnin, who is in charge of coastline defense Sigh with an exaggerated tone.

"You guys put on frogman equipment with me, and let's blow up all of Akatsuki's fleet. Although these fleets are all fake, when we report the credit, it can be said that we only used ten people. , just destroyed the enemy's fleet consisting of thousands of people, such a brilliant record is enough for us to brag about for a lifetime."

While the rest of the ninjas put on frogman equipment, they joked with their jonin captain. They didn’t have the slightest fear of the huge monsters at sea. As long as they dived underwater, it would be difficult for them to be attacked from the surface of the water. Water can Blocking most physical attacks, even the ninja who is the best at throwing, will lose all its power when his shuriken enters the water at most five meters away, and it can't even break the skin when it hits a person.

The explosion effect of bombs in water will indeed be improved to a certain extent, but sending bombs to them is not an easy task. They can be more flexible underwater than fish, and can hold their breath longer than dolphins and whales Time, unless there are ninjas of the same level with bombs and the awareness to die with them, they can use bombs to kill them underwater.

The ninjas trained by the sea are very proficient in the use of frogman equipment. Their ancestors relied on this equipment to easily wipe out the fleet of the country of water. Although the ships at that time were different from the steel monsters in front of them, It is a tall and majestic building boat built of wood, but the scene is similar to the present. They believe that they can reproduce the glory of their ancestors.

On the fleet, Xiaonan is monitoring the scanned image of the sonar. The breakthrough of sonar technology is also inseparable from her. Among the many ninjutsu, Zhidun is relatively peculiar, but after further developing her own After developing the ability, Xiaonan found that she could clearly feel the vibration of the paper. After a certain amount of training, she actually realized that she could hear the sound with her own paper after closing her hearing, and the effect was better than listening with her ears. The sound is clearer.

After discovering this, the research personnel in charge of the navy thought that her paper escape would be of great help to the development of sonar. Facts have proved that this is true. Xiaonan can use her own paper to hear ultrasonic waves. In the early days of the sonar project , that is, she uses her own paper to analyze the echoes of the ultrasonic waves emitted by the sonar.

During this process, Xiaonan herself also learned the echolocation technique. As long as she carries a sound source that emits ultrasonic waves with her, she can clearly distinguish the surrounding terrain with the paper around her.

Even so far, the accuracy of her ability detection is still higher than that of sonar equipment, which is also an important reason why she is in charge of the ship's reconnaissance.

There are frogmen stationed on the coastlines of various countries. This is something that almost all ninjas know. The frogmen in the country of water even have ghost lamps. After they turn themselves into water, they can’t even be found by sonar. They must be detected by chakra fluctuations. equipment, it is possible to detect the approach of the ghost lamp family.

The only good thing is that the chakra characteristics of the hydration secret technique are relatively obvious. Theoretically, it can detect the approach of the opponent within 500 meters. At this distance, it is theoretically still possible to intercept it.

Obviously, there are no ninjas of the Ghost Lamp family in the Land of Fire, maybe there are...but they should have been captured by Orochimaru and locked up in the laboratory for research, and they cannot appear on the battlefield.

The sonar swivels and scans. While observing the sonar, Xiaonan is also working on her own scientific research project. As for her project, it is phased array radar...

Ever since he discovered that his own paper can be sensitive to sound waves, Xiaonan seems to have developed a strong interest in waves. The principle of phased array radar is simple to say, and it uses peeling interference.

The waves released from two different sources will show interference fringes after being superimposed together, and the frequency of these two waves will be adjusted, and the abscissa of the superimposed wave on the image will change , that is, phase change, as long as certain settings are made, the interference fringes formed by this phase change can show a rotating posture. The most intuitive performance reflected on the radar is that the radar that originally needs to rotate in circles finally It can stand there honestly. Of course, the significance of practical application must be much more than this.

Xiaonan plans to start his own research attempt with sonar, which has a relatively small amount of calculation. The speed of sound is much slower than the speed of light, so it is much easier to collect data and perform calculations.

It's just that there were a few unusual fluctuations in the data she collected today, which also made her realize that her experimental project might need to be temporarily stopped.

The alarm sounded in the fleet, and the scanning direction of the sonar began to concentrate, and it was soon discovered that someone had entered the five-kilometer range of the fleet. Multi-level scanning had determined that the target was not fish or other suspended objects, but it was obviously an enemy frog. people.

"Sure enough, we are here to blow up the ship. We are about to launch torpedoes. The anti-submarine aircraft took off and dropped depth charges on the target coordinates." The fleet commander immediately issued an order. At the same time, the submarines below the fleet also locked on the enemy's position and launched torpedo attacks.

After diving into the water, the frogman jonin can also rely on his own water trap to have a vague perception of the surroundings, which is at least much farther than simply relying on visual search.

The sea water is not so clear. When you really go under the sea, the visibility will not be better than the fog. Without this kind of perception ability, if you want to go downstream to blow up the battleship, that is a fantasy.

Is it possible that you have to surface halfway through the swim to see if you are swimming in the right direction?Isn't that bullshit?The machine gun chugs immediately after surfacing.

He relies on the chakra line spreading in the water, which swings and sweeps through the water with the water flow to sense the situation in the distance. At the same time, he can feel the vibration in the water to a certain extent, which is somewhat similar to the principle of insect antennae.

Relying on this perception ability, he can roughly judge what the underwater part of the enemy looks like. Through brain supplementation, he can present a picture of the underwater scene in his mind.

Not as wide as radar, but exploration of localized areas may be clearer.

And what he sees now is a scene that makes him feel unbelievable. There is a ship that sank underwater, and it can sail underwater. The frogman Jonin, who has never seen much in the navy, saw a submarine for the first time. This kind of thing, the three views have been severely impacted.

The streamlined submarine looked like some kind of deep-sea monster, filled with a disturbing aura. At this moment, in his perception, a violent vibration came, and a certain source of vibration broke away from the submarine. They are approaching him at high speed.

"Quick retreat! The enemy has found us! Damn it, how did they do it? Is that a ninja that was dispatched just now? The speed is so fast, how can humans reach such a high speed underwater?" the frogman endured. Quickly approaching the source of his vibration, he felt the three views being severely impacted again for a while.

The other ninjas didn't have as strong perception ability as the leader, but the sixth sense still gave them a sense of danger, as if something bad was about to happen.

Immediately they made a decision to quickly dive to the deeper water. Ninjas are very resistant to pressure. Their bodies have been well trained and have already exceeded the limits of ordinary people's bodies, even without any equipment. , diving to a depth of about 500 meters is also completely tolerable.

Of course, if it exceeds this depth, even Jonin may be crushed to death by the water pressure. The water pressure at that depth has reached [-] atmospheres, and some submarines of poor quality cannot reach this depth.

However, apart from ninjas, there are no artificial objects that can reach this depth before. Therefore, ninjas who can hold their breath underwater for a long time often dive underwater instead of thinking about surfacing when they encounter danger. Dodge.

No matter what direction the attack came from, the ocean would weaken it.

However, the speed of the enemy is too fast, and it seems that they have locked their position by some means. When they dive, the shakers approaching at high speed also dive.

Although this reduced his speed, he still couldn't get rid of the pursuit by swimming. Even if the ninja used the instant body technique underwater, he couldn't move very far at high speed, so he could only watch helplessly. The torpedo is getting closer and closer.

After reaching the range where the field of vision can play a role, it was too late for any evasion. Frogman Jonin finally saw clearly what was approaching him at high speed. It was a strangely shaped underwater vehicle, which looked similar to The submarine he had seen before was similar, only more rounded.

He dodged as much as possible, and his dexterous body finally allowed him to avoid the impact of the torpedo. However, the torpedo was detonated remotely. Just when he was relieved and thought he had escaped the attack, it exploded underwater .

The shock wave spread out in the water. To the ninjas present, the shock wave was like hitting the concrete floor on their face at supersonic speed. There was almost no room for struggle, and they were torn to pieces in the explosion.

The depth bombs dropped by the anti-submarine aircraft whipped their corpses repeatedly to ensure that all the sneak attacking frogmen were wiped out.

On the shore, the ninja, who was waiting for the captain's return, saw a plane dropping bombs underwater, and couldn't help laughing out loud: "Who can be bombed with just such a mess? I think it can be used to fry fish." There was a burst of laughter from the shore, and no one realized that their captains had buried their bones in the deep sea, and they were still on the shore, looking forward to the spectacular scene of the fleet sinking to the bottom of the sea amidst the explosion.
