Admiral Middle Age

Lin Jianguo suddenly thought that because of the influence of water, people's sight distance is extremely limited underwater, and as the water depth increases, this distance disadvantage will become more and more obvious.Especially after reaching Shi Linyao's current depth...

It seems... I have come into contact with the camera on the Shilinyao bridge before... At that time, what I saw under the light was only the small part of the bow where the light irradiated, even the position of the torpedo tube on the bow. Didn't see it, only saw the few newly added scars on the front deck.

That is to say, according to the water depth where Shi Linyao is now, the surveillance camera is simply unable to allow me to see how far beyond her hull in the dark underwater environment outside.

So what was it that she made herself look out of through the camera?

"I will work hard, and I will let you know if there is a situation. In addition, in terms of the function of the underwater camera, you can see if it can increase the low-light and infrared vision, and increase the observation effect and distance, otherwise I am afraid that it will not be able to monitor. You have to be more careful yourself, you can't completely rely on me, pay more attention to the observation effect of the sonar. Don't worry, as long as you need it, the admiral will try my best to help you."

No matter what the purpose of my ship girls is, as long as they make a request, then I will try my best to help them complete it. If I can help them a little, that is the best.

With such an awareness, Lin Jianguo sat upright and raised the tablet to his eyes: "I'm ready, I can link the data, let's start."

"...Thank you admiral." Shi Linyao was a little moved. When the admiral paused just now, Shi Linyao was still very worried that the admiral would refuse in the future.

Because of the admiral's pause, it is obvious that he may have discovered that he asked him to help monitor the underwater video. In actual underwater combat, it is actually not very useful.

At such a deep water bottom, there is no light, and the only places that can be seen by the line of sight are objects that emit light by themselves or within the range of the light emitted from the submarine, and they must also be objects that can reflect light.These make the distance that can be observed extremely limited.

It can be said that if the attack has reached the point where it can be seen by the eyes, whether it is evasion or interception, it will definitely be too late in terms of time-just above this distance, the shock wave when the torpedo explodes, It can cause irreparable damage to the submarine.

As for other countermeasures, let’s not talk about whether there is such a chance, encountering that kind of suitable terrain within such a short distance, can complete the isolation of the shock wave, there is... remember, I learned it in middle school Introduced in physics, the conduction standing under water is diffused in all directions.

So even if you have a suitable terrain that can block the impact of the first wave of direct shock waves, you still have to guard against the secondary shock waves that follow, and guard against this kind of shock waves that push you before you hit it. Hard objects that block the protective effect.

I don’t know if the admiral has already understood his intentions. Anyway, he has now discovered the limitation of detecting the enemy’s situation through the visual system underwater. He found that in this underwater position, ordinary optical photography equipment cannot Get enough vision.

So he reminded himself to replace the external optical collection equipment with a low-light camera or an infrared camera.

He also deliberately made himself pay attention to safety.

This made Shi Linyao feel very moved.

Looking at the admiral on the screen, his admiral has already made preparations with a serious face. This is because he is really helping himself: "Okay, I will link you with the data link of the video head on the bridge immediately, and as soon as possible Replace those cameras with the latest low-light lenses and infrared lenses, um, and leave a dedicated communication channel for you, if there is any situation, you can notify me at any time."

In the admiral's network, Shi Linyao contacted Peace Ark and asked her to help provide the latest and most advanced low-light lens and infrared lens data.Then she is ready to learn, understand, master, and manifest as soon as possible.

In terms of learning ability, she is still full of confidence in herself.

"Well, okay, be careful yourself." The data connection is fast, and at this moment, the tablet in his hand has switched to the screen.

Lin Jianguo nodded and began to seriously check the linked video data.

"Admiral, thank you for your hard work." The voice of Xiaojian Niang came from the player.

Lin Jianguo nodded, did not reply, but looked at the tablet in his hand seriously.

The flat screen is evenly divided into left and right halves, and the images on both sides are almost exactly the same darkness.

Shi Linyao, who is sneaking, has turned off all the light sources that can be seen outside the ship: when England issued a warning before, she discovered that as a ship's mother, she can stand outside the ship, use her eyes, and use her own visual system to directly Looking around, the ears can also receive the sound in the water, and the distance and effect are very similar to sonar.

This was impossible and difficult to do when she was a submarine before—but her eyes are equivalent to installing a visual camera on the ship that can move the entire ship.

This is great.

As far as others are concerned, she believes that the deep sea chasing behind should be able to do the same.

So she turned off all the luminous light sources outside the ship, and also controlled the lights on the ship, so as to avoid being seen by the deep-sea ship mother with the 'naked eyes'.

As for the hearing system... It is a passive sonar receiving system with a longer detection range and better detection effect-her pair of small fleshy ears.

Similarly, she felt that the deep sea should have the same function.

But that can't be helped. Whether it's engine silencer or hull noise reduction, it's not something that can be done in the short while after being chased. We can only record this matter in a small notebook and leave it in a less dangerous place in the future. Time to improve ideas.

Alas, this small book has already recorded the research tasks of the missile launch system, the precision guidance system, and the data communication system. Now add the tasks of engine noise reduction and hull noise reduction... In the future, there will be some busy.

The functional limitation of the hull also caused the tablet in Lin Jianguo's hand to be divided into two parts, the front and the back, but the two parts are almost exactly the same as a black screen—although in the legendary deep sea, There are some fishes or other creatures that can emit light by themselves, but the sound Shi Linyao made when walking was so loud that even the great white sharks were frightened and ran away early when they heard it. This made Lin Jianguo feel a little pity. Saving one side.

It’s just that if you stare at the tablet carefully for a long enough time, and compare the two sides, you can still find some differences on the screens on both sides: on the right side of the tablet, it corresponds to the orientation towards the rear of Shilinyao’s hull. That camera, on that digitized screen, you can see some dim red light that suddenly flashes indistinctly.

Like the faintly shining lightning behind thick dark clouds.

Then after a while, there will also be a faint dull voice - Shi Linyao also linked the sound collection equipment on the hull.

This, it should be that the deep sea behind is attacking with depth charges.

It seems that they have tracked down Shi Linyao, but they still can't predict the specific location of Shi Linyao: Although the speed of sound in water can reach more than 1500 meters per second, Shi Linyao's voice can be heard in the place where the water depth is nearly 300 meters. The sound, when they listened to it, the delay time was only about 15 seconds, but the falling speed of the depth charge was only 6 meters per second.

This speed is not too slow, and the speed of the average person's 20-meter sprint is only a little faster than this speed-this does not include those [-]-meter sprints that need to run for more than [-] seconds, and it is not necessarily guaranteed to be completed 'House' people.

It's just that even at this speed, by the time the bomb fell to the location of Shilin Kiln, nearly a minute had passed.

According to Shi Linyao's underwater speed of 30 knots per hour, she should already be 500 meters away when the depth charge falls to the position where she makes the sound. At this depth and distance, all Lin Jianguo can see is The red light that appeared when those looming bombs exploded.

Coupled with the absorption of nearly 300 meters of sea water, the cover of various background sounds, and the interference of the noise caused by the advance and attack of the deep-sea fleet.

So in fact, it is not so easy for Shen Hai to accurately determine the exact location of Shi Linyao.From time to time, they would lose Shi Linyao's trace on the sonar because of the interference caused by the explosion of the depth charges.

It’s just that compared to their sonar listening technology, if Shi Linyao really wanted to get rid of them, seize a chance of a depth charge explosion, suddenly shut down and stop, and disappear all sonar traces, they would be caught blind.

Fortunately, Shi Linyao had other ideas and did not intend to completely get rid of them, but sailed at full speed on the bottom of the sea arrogantly.

Therefore, their attacks can only be based on the faint traces of Shi Linyao's flickering and flickering observations, seize every opportunity, focus on the general direction, and cover a large area with firepower - it is also a loss It's the deep sea, and with other types of ships, I'm afraid they have run out of ammunition and food for such salvos again and again.

It's just that Shi Linyao's walk on the bottom of the water is not a straight line, but a three-dimensional wavy line with ups and downs. In addition, Shi Linyao adjusts the power of the engine from time to time, which makes the power of her hull The sound was even more unpredictable and variable in size - with an anti-submarine master like England by his side, if he didn't learn a few things well, it was obviously not in line with Shilin Kiln's habits.

This method of confusing the opponent by changing the position and actively changing the noise level was developed by Shi Linyao, England, and Katyusha together. From the current point of view, this method is the most effective in actual combat. It is still possible.

It's just that this kind of form of being chased and beaten by people is still quite dangerous for Shi Linyao, just like the previous time, if one is not careful, maybe a piece of cloud will be destroyed. A piece of rain fell—after all, when attacking underwater targets, the landing points of depth charges and torpedoes are also quite Buddhist: maybe, if you flick the tail of the inner fish you meet halfway, it will Let the depth charges and torpedoes deviate from the intended target.

Submarines are still too fragile when they are on the bottom of the sea.Under the huge pressure of the sea water, at this time, any explosion at close range may become the last straw that crushes the camel's camel: in the previous wave of torpedo salvo, two torpedoes were lucky enough to hit Shilin Near Yao, there was a problem with Shi Linyao's propulsion system caused by the concussion.

"Or... let Dafeng and Lexington send planes to bomb them." After hesitating for a while, Lin Jianguo said cautiously: "The minefield is reserved for any accidents that may occur behind Katyusha. Bar."

"It can be regarded as more preparation."
