"Lao Tzu's submarine force is raised by the stepmother, and there is no support! Just tossing in his own family, Sa Zhenbing, this kid is an anti-submarine destroyer and an airship, isn't this bullying? In the conference room, Cai Tinggan scolded and said. Cai Tinggan really didn't expect that at the last moment, he would be able to escape and go back to claim the prize, but he let a flying ship swaying in the air be disposed of!

IF IT IS IN ACTUAL COMBAT, THIS AIRSHIP CAN REDUCE THE ALTITUDE AND THEN USE THE 47MM RAPID-FIRE CANNON IN THE POD TO BEAT THE SUBMARINE INTO A SIEVE, BUT THE SUBMARINE HAS NO WAY AT ALL, IF YOU DIVE, THE AIRSHIP REALLY CAN'T HIT YOU, BUT PEOPLE CAN WAIT, YOU CAN'T CHARGE ON THE SURFACE, AND YOU CAN'T MOVE UNDER THE WATER, AND YOU ONLY HAVE TWO ENDINGS THAT EITHER SUFFOCATE UNDER THE WATER, OR COME UP TO DIE. If you dare to drive on the water, follow until you beat the submarine into a sieve!

"Okay, let's get ready for a meeting, it's not enough to sink a ship." Just as Cai Tinggan was complaining, Yang Yonglin walked in and knocked on the table, followed by Sa Zhenbing, who was pale. Sa Zhenbing was naturally not in a good mood if he lost the exercise, Cai Tinggan won, and it is okay to play a live treasure without doing anything, but it can't be too much, it will affect unity.

"By the way, Commander, we still have a submarine waiting at the entrance to Dalian Bay, how is this submarine? Why haven't you heard from them since you came back? Cai Tinggan asked suddenly. After being discovered by the airship, he immediately sent a telegram to the Sea Tiger 3 submarine, meaning that the mission had been completed and it was time to retreat. However, after sending the telegram himself, he did not receive a reply from the Sea Tiger 3 until the return voyage. This made Cai Tinggan very uneasy in his heart.

"You mean the Sea Tiger No. 3, now stranded and being rescued. But you don't have to worry about people, they have all been rescued, and now everyone is towing the submarine. Sa Zhenbing said with a wicked smile. Let you wait for the rabbit at your doorstep! Now dumbfounded, the port itself is very narrow, and there are lightning nets. The underwater environment can be said to be quite complicated, usually submarines walk on the surface of the sea to watch the buoy enter the port, and now it is abnormal to walk underwater and cannot find a reference object! ”

This is not to say that the level of training of the submarine forces of the Chinese Navy is too low. Rather, it was too difficult, and even in World War I, the German Navy sent 8 submarines to attack the British Royal Navy anchorage at the beginning of the war. Two of the submarines were forced to return due to mechanical problems, one submarine was sunk by the light cruiser Birmingham, and the other five did not achieve the slightest success, partly because the performance of the submarines at that time was really tragic. On the other hand, it is also because the environment is too complex. Various shoals, mine nets and mine arrays make it difficult for submarines to move an inch. By the way, there may be deliberately sunken ships blocking the channel, in short, it can be described as nine deaths. Therefore, Cai Tinggan's plan seems to be good, but the feasibility is not high.

Although the exercise was over, the smell of gunpowder at the venue was still very strong, and Sa Zhenbing repeatedly stressed that it was because of the fixed voyage that caused the "sinking" of the Weihai, and if his own voyage was not fixed, it would not be easy to sink the cruiser in the face of a high-speed voyage that was constantly changing course. Of course, Sa Zhenbing also admits that after "wrecking" a submarine. He was a little careless, he really didn't expect someone to have N more back-hands!

And for Sa Zhenbing's rhetoric. Cai Tinggan actually agreed very much, almost all members of his submarine detachment attacked an armored cruiser with so much effort, and almost all the troops were wiped out after the last day, if you face the Russian Grand Fleet, there are hundreds of capital ships and auxiliary warships, and you will be lined up on a battle line several kilometers long, if you go up, you will really be looking for death, and no matter how slow the movement speed of the Grand Fleet is, it is more than 12 knots, and you must not be on the water in the past, and if you go underwater, you will not be able to go long before the fire is extinguished! can only ambush, and the tactics of ambush may not work, at most once or twice, no matter how many people are prepared, it will be too difficult to attack the large fleet, don't be too troublesome, the escort battleship will not dare to take the lead when it opens the way in front, and if you change the route, you can't even find it! As for going to the port to directly "assassinate", the Sea Tiger 3 is already an example, unless it is absolutely necessary, Cai Tinggan is not like an adventure, the lightning protection nets and anti-submarine nets in the port of Batavia are definitely a nightmare for submarines!

"I think that the main task of the submarine forces should be to attack the transport ships of the opposing side, as well as reconnaissance. Attacking the fleet is really not a very reliable thing, the danger is too great, the difficulty is too high. Unless we know in advance the enemy's voyage, it will be very difficult to find a fleet in the vast sea, and even if we find the opponent's fleet, if there are many destroyers, the probability of failure is very high. Cai Tinggan said.

"However, although it is inconvenient to attack a dynamic fleet, and it is dangerous to attack a fleet in a harbor, submarine forces can still carry out offensive minelaying outside the opponent's harbor. In addition, considering that the range of submarines is on the short side, I hope to provide special camouflaged refueling ships and supply ships for submarine forces. The fuel load of a submarine is only about 60 tons, and a ship can provide enough fuel for 8 submarines of a submarine squadron for 1 month. Don't get too far ahead, just help from a base in Malaya and Sarawak. Torpedo replenishment is not very important, because in the face of merchant ships, it can be solved with naval guns. DON'T LOOK AT THE 105MM ARTILLERY, IT'S ENOUGH TO DEAL WITH MERCHANT SHIPS. Cai Tinggan added.

"Since Colonel Cai Tinggan talked about the practical methods of submarines, I basically agree, although my mistake caused the sinking of the Weihai, but I still think that the submarine force has limited lethality against a well-protected fleet. Of course, for a lone battleship or small formation, the tactics of ambushing at a predetermined location can still have a good effect. At the same time, I feel that the tactics of submarine cluster attack used by Colonel Cai Tinggan this time will be difficult to implement in the open sea, after all, our submarines are scarce, and the sea area to be taken into account is too large, plus the problem of communication. The actual effect of submarine group operations is actually not as good as that of single-boat safaris. Submarines are assassins, and who has ever seen assassins come out in droves to assassinate? Sa Zhenbing said.

"But this time Sa has something new about anti-submarine warfare, submarines are like those assassins with lethal weapons but a very close range, their range is extremely limited, and the time under water is not long, so what we need to do is to increase our anti-submarine depth as much as possible, the distance between the frigate and the capital ship must be large, and the number must be large, and we can also send frigates to sweep before the capital ship enters the war zone. Do not seek to sink the opponent's submarine, at least ensure that the opponent's submarine cannot attack. After Sa Zhenbing finished speaking, he looked at Cai Tinggan, who was sitting opposite.

"I would like to add that the amount of air power is very lethal for submarines!" Cai Tinggan added. It's not that airships can carry a lot of depth charges. The key is because of the relationship between the height, the airship can conduct a large-scale reconnaissance of the sea surface, even if a submarine escapes with all its might, it is impossible to escape the reconnaissance range of an airship, the range of 8 nautical miles is 15KM, in the face of a few hundred meters or even higher airships, in the case of an observation radius of more than 40 kilometers at this position, the submarine is almost impossible to escape, because once the power is out, it will be charged on the float, and the smoke generated by the diesel engine will also let the other party find your whereabouts, don't forget, Your background is a blue sea!

"At the same time, at the flotillary mooring, we should strengthen the mine array and anti-submarine nets, and if necessary, we can also sink ships in advance to block the channels that some submarines can use, if it is stationed at sea, the light control must be strictly enforced, and at the same time, each capital ship must put down the mine protection nets when it is berthed. In addition, we need to increase the number of convoys so that we can provide escort for troop carriers or quartermasters, even if it is one, it is a deterrent for submarines. Sa Zhenbing quickly jumped his mind from the fleet to the transport ship, after all, there are thousands of soldiers and thousands of tons of supplies on a transport ship, if one is dropped, of course it hurts!

"You mean the establishment of an escort system? This idea is good, but maybe there are not enough frigates, even if it is difficult to modify civilian ships, it is better to recruit a large number of high-speed merchant ships and large-range merchant ships, the former can effectively avoid encountering submarines, the maximum surface speed of submarines is about 14 knots, submarines are generally on the surface to search for the enemy, found before diving closer, the time on the water is much longer than the time underwater. If the merchant ship can reach a speed of 20 knots, it can easily shake off the tracking of opponents. How can an enemy submarine attack if it can't even track it? Gradually, Cai Tinggan actually considered how to deal with the submarine force as an opponent, after all, in the entire Huaxia Navy, he was the only one who specialized in submarines, and he also knew the characteristics of this kind of thing best.

In short, this meeting was very successful, after this confrontation exercise, both the submarine side and the anti-submarine side have gained a lot, Cai Tinggan will not go to the big fleet of the Russians all day long to think about as before, what he is thinking about now is how to send the fleet of supplies to Russia and the Netherlands to the bottom of the sea one by one, and then replace his epaulettes with a general star. This will be very good-looking, (the tonnage of ocean-going merchant ships is large~~) The effect is also very large, (even a shipload of coal can be worth a lot of money.) Of course, the biggest benefit is that there is less risk!

As for Sa Zhenbing, it is a little difficult, because there are two paths in front of him now, the first way is to enter the fast fleet after Liu Buyun comes back and serve as the captain of a certain capital ship, and the other way is to be a "child king!" "With a big ticket of boats and airships all day studying how to fight these loaches in the water! The former was his lifelong dream, while the latter fascinated him because, in his opinion, the work was very exciting and, more importantly, challenging!

As for Yang Yonglin, he is very busy now, because in addition to reporting the situation of submarine warfare to Xu Jie, he is also preparing for the return of Liu Buchan's fleet, after all, what about the 7 dreadnoughts, the berth supply and so on are all big problems.

Thank you for the reward of dsbghost~~~. (To be continued......)
