The navy has always existed in the world of Naruto, and it has developed to a relatively developed level in the future, with aircraft carriers being 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 destroyed by ninjas. Facing ships, ninjas can dive into the water and use ninjutsu to destroy the ships, but defending against this damage is far more difficult than the destruction itself.
many.
This makes it very costly to build large ships in the ocean. Ninjas can use frogman tactics to easily destroy a large number of warships in the ocean with a small but powerful force.
If this problem cannot be solved, it will be difficult for a large-scale navy to appear in the world of Naruto.
Akatsuki is also aware of this problem, and the idea to solve this problem is to enhance the underwater detection capabilities and enhance the accuracy of the sonar carried on the fleet during the detection process.
In this way, once someone approaches from underwater, the difficulty of discovery will be greatly reduced, and there will be room for interception.
All torpedoes can be intercepted, not to mention ninjas moving forward underwater. Ninjas may be very good at swimming underwater, or even transform themselves into a shark-like form, allowing them to achieve extremely high speeds underwater.
But compared with torpedoes that use the supercavitation effect, the speed is much different. It is not at the same order of magnitude, and the gap cannot be made up by modifying the body structure and speeding up swimming.
As long as the enemy can be discovered, whether it is with torpedoes or depth charges, there is always a way to intercept it. Especially the shock wave of the explosion, both in terms of propagation speed and power are greater in the water than in the air. If it is hit, it will cause
For more serious injuries, it would be difficult for ordinary ninjas to withstand this level of damage.
The jonin may be able to withstand the shock wave of the explosion and continue to complete the task of destroying the ship, but at that point, the ninja needs to consider the cost on his own side.
Is it worthwhile to exchange a Jonin for a warship of the other party? A Jonin is as valuable to a country as the top fighter jets. If they implement frogman tactics, the cost-effectiveness of this tactic will drop significantly.
, lost its strategic significance.
It was the increasingly mature radar and sonar technology that made Akatsuki determined to build its own navy. Although there was no outlet to the sea on the mainland, there was an outlet to the sea in the south of the neighboring country of Kawa. As a staunch ally, Akatsuki borrowed the other party's port to build its own navy.
There is absolutely no problem in building your own navy.
All this time, the navy has been hiding in the snow and has not participated in the war. Ninjas from major countries have actually discovered fleets at sea, but no one paid attention to them.
From their point of view, Akatsuki was just out of money. What was the use of throwing so much high-quality steel into the sea? Any ninja who touched the bottom of their ship could sink it.
It was with this mentality that the ninjas of the Fire Country did not panic when they saw the huge fleet approaching the coastline. Instead, they sneered with disdain.
"I have invested so much money to build such a behemoth without fully understanding what a ninja is. It's such a waste. I'm a little reluctant to blow up such a beautiful model and sink it to the bottom of the sea." A jonin in charge of coastline defense
Sigh in an exaggerated tone.
"You guys put on the frogman equipment with me, and let's go and blow up all the Akatsuki fleets. Although these fleets are all fake, when we report the results, it can be said that we only used ten people.
, we destroyed the enemy’s fleet consisting of thousands of people. Such a glorious achievement is enough for us to brag about for a lifetime.”
While the other ninjas were changing into frogman equipment, they were joking with their jounin captain. They were not afraid of the behemoths on the sea. As long as they dived underwater, it would be difficult for attacks from the surface to do anything to them. Water could do anything to them.
Isolated from most physical attacks, even a ninja who is best at throwing will lose all power after his shuriken enters the water and can fly up to five meters. If it hits a person, it will not even break the skin.
The explosion effect of bombs in water will indeed be improved to a certain extent, but it is not easy to deliver bombs to them. They can be more flexible than fish underwater, and can hold their breath longer than dolphins and whales.
Time, unless there are ninjas of the same level who carry bombs and have the consciousness to die with them, they can kill them underwater with bombs.
The ninjas who trained on the beach were very skilled in the use of frogman equipment. Their ancestors once relied on this equipment to easily destroy the fleet of the Kingdom of Water. Although the ships at that time were different from these steel monsters in front of them,
It was a tall and majestic ship built of wood, but the scene was similar to what it is now. They believed that they could recreate the glory of their ancestors.
On the fleet, Xiaonan is monitoring the scanned images of sonar. The breakthrough progress of sonar technology is also inseparable from her. Among the many ninjutsu, Paper Release is considered to be relatively unique, and after in-depth development of its own
After gaining the ability, Xiaonan found that she could clearly feel the vibration of the paper. After some training, she was able to hear sounds with her own paper after closing her hearing. The effect was better than listening with her ears.
The sound is clearer.
After discovering this, the scientific researchers in charge of the navy believed that her paper escape would be of great help to the development of sonar. Facts have proved that this is indeed the case. Xiaonan can use her own paper to hear ultrasonic waves. In the early days of the sonar project,
, she used her own paper to analyze the echoes of ultrasonic waves emitted by sonar.
In the process, Xiaonan herself also learned the technique of echolocation. As long as she carries the sound source that releases ultrasonic waves with her, she can use the paper around her to clearly distinguish the surrounding terrain.
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 responsible for on-board reconnaissance.
There are frogmen stationed on the coastlines of various countries. This is something that almost all ninjas know. There are even frogmen from the Kingdom of Water, including the Ghost Lantern clan. After they turn themselves into water, they cannot even be detected by sonar and must use chakra fluctuations to detect them.
Only with this equipment can we detect the approach of the Ghost Lantern Clan.
The only good thing is that the chakra characteristics of the hydration secret technique are relatively obvious. Theoretically, the opponent can be detected within 500 meters. At this distance, theoretically there is still time to intercept.
There are obviously no ninjas from the Oniden clan in the Land of Fire. Maybe there are... but they should have been captured by Orochimaru and kept in a laboratory for research. They are unlikely to appear on the battlefield.
The sonar rotated in circles. While Xiaonan was observing the sonar, she was also working on her own scientific research project. As for her project, it was a phased array radar...
Ever since he discovered that his paper can be sensitive to sound waves, Xiaonan seems to have become very interested in things like waves. The principle of phased array radar is simple to say, it uses peeling interference.
When waves released from two different sources are superimposed, interference fringes will appear. By adjusting the frequencies of the two waves, the abscissa of the superimposed wave on the image will appear.
There is a change, that is, a 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 manifestation on the radar is that the radar originally needs to rotate in circles.
, it can finally stand there honestly. Of course, the practical application significance must be much more than this.
Xiaonan is going to try to conduct his own research first with sonar, which has a relatively small amount of calculations. The speed of sound is much slower than the speed of light, so it is much easier to collect data and perform calculations.
However, there were several unusual fluctuations in the data she collected today, which made her realize that her experimental project might need to be temporarily stopped.
The alarm sounded in the fleet, and the sonar scanning direction began to focus. It was soon discovered that someone had entered within five kilometers of the fleet. Multi-level scanning has determined that the target is not a fish or other suspended objects, but is obviously an enemy frog.
people.
"Sure enough, we are here to blow up the ship. Prepare to launch torpedoes. Anti-submarine aircraft take off and drop depth bombs at the target coordinates." The fleet commander immediately issued the order. At the same time, the submarine below the fleet also locked the enemy's position and launched a torpedo attack.
After diving into the water, the frogman jounin can also rely on his water escape to sense the surrounding lake. This is at least much farther than searching by sight alone.
The sea water is not that clear. Once you go under the sea, the visibility will not be any better than in the fog. Without this kind of perception ability, it would be impossible to swim under the water and blow up the warship.
Is it possible that you have to surface halfway through the swim to check if you are swimming in the right direction? Isn’t that nonsense? You have to let the machine gun go out as soon as you surface.
He relies on the chakra lines spreading in the water, which sweep through the water as the current swings, to sense the situation in the distance. At the same time, he can feel the vibrations in the water to a certain extent, which is somewhat similar to the principle of insect antennae.
Relying on this kind of perception ability, he could barely judge roughly what the enemy looked like underwater. Through brainstorming, he could present a picture of the underwater scene in his mind.
It does not have a wide range as radar, but the exploration of local areas may be clearer.
And what he saw now was a scene that made him feel incredible. There was actually a ship that sank underwater and could sail underwater. It was the first time that a frogman Jonin, who had never seen anything in the Navy, saw a submarine.
This kind of thing has severely impacted our outlook on life.
The streamlined submarine looked like some kind of deep-sea monster, and it was filled with an unsettling aura. At this moment, in his perception, violent vibrations came, and a certain source of vibration broke away from the submarine.
It was approaching in his direction at high speed.
"Quickly retreat! The enemy has discovered us! Damn it, how did they do it? Is that a ninja who just dispatched? It's so fast. How can humans reach such a high speed underwater?" The frogman Jonin felt.
He quickly approached the source of his vibration, and for a moment he felt that his three views were violently impacted again.
The other ninjas did not have as strong a sense of perception as the leader, but their sixth sense still gave them a sense of danger, as if something bad was about to happen.
They made a decision immediately and quickly dived to the deeper water. Ninjas are very resistant to pressure. Their bodies have been trained for a long time and have already exceeded the limits of ordinary people's bodies, even without the help of any equipment.
, diving to a depth of about 500 meters is completely bearable.
Of course, if it exceeds this depth, even a Jonin may be crushed to death by the water pressure. The water pressure at that depth has reached fifty atmospheres, and some submarines of inferior quality cannot reach this depth.
However, except for ninjas, no man-made objects have been able to reach this depth before. Therefore, ninjas who can hold their breath underwater for a long time often do not want to surface when they encounter danger, but dive into the water.
To avoid.
No matter which direction the attack comes from, the ocean will weaken it.
However, the enemy's speed was too fast, and they seemed to have locked their position through some means. As they dived, the vibrators approaching at high speed also dived.
Although this has reduced his speed, it is still not possible to escape pursuit by swimming. Even if a ninja uses the teleportation technique underwater, he cannot move very far at high speed and can only watch helplessly.
The torpedo is getting closer and closer to me.
After reaching the range where the field of vision was effective, it was already too late for any avoidance. The frogman Jonin finally saw clearly what was approaching him at high speed. It was an underwater vehicle with a strange shape. It looked similar to
The submarine he saw before was somewhat similar, only more rounded.
He tried to avoid it as much as possible, and his dexterous body finally allowed him to avoid the torpedo's impact. However, the torpedo was detonated remotely. Just when he breathed a sigh of relief and thought he had escaped the killing blow, it exploded underwater.
.
The shock wave spread out in the water. For the ninjas present, the shock wave was like a cement floor being slapped on their face at supersonic speed. There was almost no room for struggle and they were torn into pieces in the explosion.
Anti-submarine planes dropped depth bombs and whipped their corpses repeatedly to ensure that all the frogmen who made the sneak attack were wiped out.
On the shore, the ninjas waiting for the captain's return saw a plane dropping bombs underwater, and couldn't help but laugh: "Who can be hit by just such a random bombing? I think it can also be used to fry fish."
There was a burst of laughter from the shore, and no one realized that their captain had been buried deep in the sea. Everyone was still on the shore, eagerly waiting for the spectacular scene of the fleet sinking to the bottom of the sea in the explosion.
