Episode 123 The road is one foot high, and the magic is one foot high

This is not a design adapted to the current mode of submarine warfare. On the contrary, it is tailor-made for future submarine warfare. Every new feature of the submarine warfare will be adapted to the new mode of submarine warfare in the future.

"Oh?" Sun Tingyu asked, "How can you see it?" ”

Xiang Xiaoqiang says:

"The current submarine warfare is nothing more than a submarine single-handedly roaming the sea, finding a cargo ship approaching, warning, ordering the ship to stop for inspection, and then sinking it. Of course, the other party will not stop the boat as usual, but will only step up and escape. And our submarine, as usual, went through the motions and fired a torpedo and sank. This is regular submarine warfare, or 'limited submarine warfare', which is very inefficient, but barely sustainable. Why? Because the other side does not have a warship to escort it. Our submarines can chase cargo ships at high speeds on the surface of the water, and there will be no problems.

"But what happens when you run into an enemy warship or an enemy plane? Our submarine has only one option: abandon the prey and make an emergency dive. The problem is that the current submarine can only reach a few knots underwater, and once it dives, it means that it will not be able to do anything, and it is equivalent to declaring that it has given up hunting, giving up combat, and only seeking to save its life. Not only was the prey that he finally encountered lost, but it was difficult to say whether he could even save his own life. It can be said that from the moment the submarine gave the emergency diving order, the fate was not in its own hands, and it was all left to God. ”

Qiu Yu felt the same way, and nodded vigorously:

"Uh-huh!"

Sun Tingyu said with a smile:

"But Lord Xiang, what is the probability of this situation you are talking about? How many times have our submarines encountered Japanese warships in the vast ocean? How many times have you encountered Japanese planes? Ten times we sink a Japanese freighter, we will not necessarily encounter a Japanese warship. For the sake of this one-tenth, one-tenth encounter, is it necessary for us to design a submarine specifically? Then again, if you really have to encounter it once, then the dive is. …… Hehe, the old man speaks more straightforwardly, don't be surprised by the adults. ”

Xiang Xiaoqiang smiled:

"Where is it, I, a junior junior, have an axe in front of your old man, and I ask your old man not to be surprised. …… Yes, at present, the probability of our submarines encountering Japanese ships and planes is not high. But don't forget, old man, that in the Great War in Europe, the Atlantic battle between Britain and Germany was also in our current situation at the beginning. The Entente cargo ships sailed alone, and the German submarines also hunted alone, and the probability of directly encountering the Entente ** ships on the ocean was quite low. But what happened then? After suffering huge losses, the Entente learned the power of submarine warfare and adopted a new tactic: the convoy escort system. They assembled the cargo ships that had been sailing alone into a large fleet, escorted by warships.

In this way, the cargo ships that were originally scattered on one surface were concentrated into one point, and the probability of being discovered by German submarines was greatly reduced, and even if they were discovered by German submarines, then German submarines would have to face several or a dozen destroyers single-handedly. What to do with the submarine at this time? To dive or not to dive? If you don't dive, it will definitely be a dead end in the face of the absolute superiority of the enemy ships. diving, it is equivalent to announcing the withdrawal, just seeking to save your life. Even if it's not a deep dive, but only a dive to the periscope depth, then you can only hit and run. Because as long as they stay below the surface, submarines can't catch up with even the slowest cargo ships. Moreover, as long as a torpedo explodes, it is equivalent to announcing its existence to the escort ships of the entire fleet.

"Then at this time, even the most brave captain can't help but give the order to dive. At least you have to dive to a few tens of meters, or you have to dive to hundreds of meters. Once you dive deeply, not only can you not even use the periscope, but it is not said that you can float up if you float up. As you know, there is a limit to the amount of compressed air stored inside a submarine. Toss up and down a few times, and once the compressed air runs out, you can't float anymore. If you want to replenish the compressed air, you need water. Out of the water is out of the water, and other escort ships are raising cannons, waiting for you to get out of the water.

"The whole fleet will take advantage of the submarine to dive, accelerate, turn, and use the speed advantage to disengage the submarine, while the destroyer constantly throws depth charges on the submarine. It is best to blow up the submarine, and if it is not blown up, it can also force the submarine to stay underwater for as long as possible, giving the fleet as much time as possible to diverge. A few hours later, or a dozen hours later, when the submarine surfaced with half a dead and frightened body, the sea was empty and there was nothing. Everything had to start all over again.

"After so much effort, I almost put my life on the line, in exchange for what? Sink a maximum of one or two cargo ships. Sometimes even one was not sunk, but only half of it was damaged. And let this fleet go, and for a long time, nothing will be touched. This mode of submarine warfare, compared with the early mode of hunting down a single cargo ship, is obviously much harder, more dangerous, and much more effective with half the effort. Germany's unrestricted submarine warfare ended up being such a failure. …… And, of course, there's an acoustic detector. But that thing doesn't work well, and that's not the main reason. The main reason was that the Entente countries adopted a fleet escort system, and German submarines failed to adapt to this new model, either technically or tactically. ”

……

After Xiang Xiaoqiang finished speaking, Sun Tingyu was quite surprised, but he didn't expect Xiang Xiaoqiang to be an intelligence officer, and he was still an army officer, and he really knew a lot about submarine warfare. Not to mention an army officer, even if it is a naval officer, as long as he is not engaged in submarines, he is a half-understood. Listening to Xiang Xiaoqiang's tone now, he is like an old captain who has participated in the European War.

Sun Tingyu glanced at Qiu Yu next to him again, and was also relieved: Also, the wife of the person is the captain of the submarine, and she still has actual combat experience. Xiang adults must have made up lessons at home.

Anyway, he put away his contempt for Xiang Xiaoqiang. He knew that Xiang Xiaoqiang had really put in a lot of effort, not on a whim, and he came here with a slap on the brain.

Sun Tingyu pondered for a long time and said slowly:

"Lord Xiang, the old man understands what you mean. You are saying that we cannot repeat the mistakes of Germany. Just because Japan has not adopted a convoy escort system does not mean that it will never be adopted. What you mean is that we need to be prepared to get to the front of Japan, and when Japan adopts a fleet escort system, we will be able to come up with something new that adapts to it. ”

Xiang Xiaoqiang smiled and nodded:

"Hehe, exactly."

Sun Tingyu said with a smile:

"But...... Did Lord Xiang think that this new submarine would always stay below the surface and remain hidden and undetected even when attacking the fleet? ”

Xiang Xiaoqiang knew what he wanted to say. He also laughed:

"Hehe, I didn't think so. All-weather diving, this concealment is first for aircraft anti-submarine, and secondly, for underwater attacks. Today's submarines, as Mr. said, should be called "surface ships that can dive", and they usually sail on the surface of the water, and only dive for a short time when they are hiding from the enemy. Then enemy aircraft are cruising in the air, and submarines on the surface can be seen from afar. Submarines, on the other hand, often don't have time to dive safely.

"And the new submarine is cruising even below the surface, exposing the periscope and snorkel at most. It's hard to see these two tubes on the surface of the water at an altitude of a few hundred meters. Even if it is found, the submarine can quickly retract the tube and make an emergency dive. It's not the same as floating on the surface and making an emergency dive. At this time, the submarine was already below the surface, and if it wanted to dive deep, it was very fast. To exaggerate, as soon as the emergency diving order is issued, the submarine can sink like a stone. ”

Sun Tingyu thought and nodded slowly. After a while, he asked again:

"Don't forget, my lord, bombers can carry depth charges in addition to ordinary bombs. As long as the bomber sees the approximate position of the submarine when it dives, it can fly over and drop a few depth charges. ”

Xiang Xiaoqiang nodded and said:

"Sir is right, airplanes can drop depth charges. But how many depth charges can an airplane carry? One? Two? Three? It's at the top. And if you ask any destroyer captain, he will tell you how difficult it is to sink a submarine with depth charges. Sometimes it takes hours, sometimes it takes an entire day. During this period, he constantly captured sonar information, modified the depth fuse of the bomb, stopped, accelerated, reversed, left and right full rudder, and fought with the submarine, competed with patience, and dropped depth charges one after another...... In this way, it is difficult to say that the submarine was sunk. It can only force the submarine to stay underneath and buy time for its own fleet to leave. It is not easy for an airplane and a dive to blow up and sink a submarine that has already dived. ”

……

Sun Tingyu has almost been convinced. He thought about it for a long time, and then asked:

"So, my lord, what does this have to do with the 'wolf pack tactics' you mentioned?"

Xiang Xiaoqiang smiled:

"My 'wolf pack tactics' are specifically designed to deal with the 'fleet escort system'. This is called one foot high, and the magic is one foot high. Didn't they gather all the cargo ships? Didn't we not find our submarines? It doesn't matter, they cluster, we cluster. At the time of the European war, it was the British fleet that was clustered, while the German submarines were not, so that often one submarine faced a large group of escorted cargo ships alone, sinking at most one or two, while the other submarines were idle on the empty ocean, and the overall result fell geometrically. Our submarines now have to be brave enough to make contact with each other, and as soon as one submarine discovers the fleet, while keeping in touch, it sends a telegram to inform the other submarines, and immediately rush to attack in groups. It's only fair that a group of submarines attacks a group of cargo ships. The tonnage of the results can also go up.

"So what are the advantages of the new submarine? First of all, they dared to send telegrams to each other. Because it is always submarine, only the periscope, snorkel, and antenna are exposed, so even if the approximate location is detected by the enemy, it is not afraid. The enemy sends planes, often without seeing submarines. If the enemy sends destroyers, then it will not be known that the Year of the Monkey will arrive. Even if it does, it won't be overhead in the blink of an eye like an airplane. The submarine had plenty of time to dive and dodge.

"And once several submarines of our army meet up and start attacking the fleet together, the advantage of submarine navigation is great. Because of its high speed underwater, submarines can maneuver with destroyers in a fleet. At the same time, it can constantly wait for opportunities to attack cargo ships. At this time, many submarines of our army have become wolves into the flock, the entire fleet has been on fire everywhere, explosions are coming one after another, and cargo ships are sending distress signals everywhere. The sound of the engines of several submarines and the engines of dozens of cargo ships are mixed together, the smoke from the snorkels of several submarines is mixed with the billowing smoke from the sea, and the destroyers are not able to take care of one thing at all, and they want to capture submarines and have to keep saving people. Our submarines can go on a killing spree. The more cargo ships hit, the more chaotic the scene becomes, the busier the enemy destroyers, the safer our submarines will be, the more opportunities there will be, and the more cargo ships will be sunk. -- Once these two new technologies and new tactics are combined, the results will be far beyond the old mode of submarine warfare. ”

……

At this time, Sun Tingyu and several engineers stopped talking. They were all looking down in thought, staring at the blueprints of the idea of the new submarine. Qiu Yu had long been excited by Xiang Xiaoqiang's words, and sat next to him with a blushing face, as if he was already eager to command such a new submarine and go to the ocean to tear it apart.

Xiang Xiaoqiang also drank tea and looked at them with satisfaction. He knew it was almost there. The project of the new submarine can be fully supported by the old specialists of the R&D department.
