By the time the submarines were ready for the carrier battle group, all ten groups of submarines had already arrived at the side of the British Eastern Fleet.

They formed a huge encirclement, as if to guard it, and the division was on the perimeter of the British fleet.

It's just that these submarines are not here to be escorts, but to destroy the British Eastern Fleet.

When the group of dive bombers reached the skies over the British fleet, a message was sent to the aircraft carrier, and the aircraft carrier sent a message to the submarine.

"Report sir, here's a message from the Bird's Nest that the eagles have arrived and told us to get ready."

The command room of a normal submarine is very small, but there is something special about this submarine, and the command room is much larger than that of a normal submarine. A man in his early thirties was the commander of the submarine force, commanding the thirty merchant-class submarines.

The commander's name is Di Wolf, and like Liu Haijiang, he is a graduate of the first phase of the Naval Academy of the Chinese Military Academy. However, he is from the submarine command class, and Liu Haijiang is from the aircraft carrier command class. My luck is not bad at all compared to Liu Haijiang. Liu Haijiang is the acting captain of the aircraft carrier and is now the commander of the aircraft carrier battle group. Di Wolf is also the commander of this batch of submarine forces now, he did not rely on anything else to become this commander, but relied on consulting again and again, and immersed himself in various tactics, and won the first place again and again in the past competitions. Every day is a night reading, as long as it is a break, Di Wolf has not wasted a trace. It is his spirit of hard work that makes Chen Shao value it very much.

A person may not be talented now, or he may not be a genius. But as long as you have a heart of hard work, there will always be a successful day. Chen Shao just gave him a better stage to display his talents.

"Reply to the Bird's Nest, the message has been received." Di Wolf finished this with the signal soldiers beside him, and then said: "Tell the submarine teams to report their current location." ”

In this command room, there are not only Di Wolf and his group, but also two German ** officers here, who are wearing Chinese naval uniforms, standing aside and watching Di Wolf keep giving orders.

"Report to the sir, a submarine team has replied, and the first group is one nautical mile southeast of the British fleet, at a depth of one hundred and fifty meters. The second group ...... east of the British fleet. ”

"That is to say, now that we have completely surrounded the British fleet, it is good, inform the groups to wait for the order to attack." Di Wolf said with a smile on his face.

"The other party put down the sonar detector." There was a clatter coming from an instrument in the command room, and the sonar soldier in charge of the instrument whispered.

For a while, the entire submarine was as quiet as death, and everyone, including Di Wolf, was quiet. The radio was also quickly turned off.

The clatter has not stopped, which means that the other party's sonar has been detecting. Di Wolf asked in a low voice, "What is the depth of the dive now?" ”

"One hundred and sixty meters!"

"General Di, have we been discovered?" The German ** officer on the side walked behind Di Wolf and asked in a low voice.

"No, according to British detection technology, it is impossible to find us below 50 meters, let alone that we are still at the bottom of the sea at 160 meters, it is even more impossible. And our submarines did not rise either, basically all of them were below a hundred meters. It is very likely that the other party is suspicious, but this British commander is quite alert! There are two brushes. Di Wolf replied.

"I thought we were discovered, but we know Keith very well. In 1918 he was promoted to lieutenant general and served as commander of the Dover Patrol Fleet, where he fought against our submarines, and led the fleet to attack our submarine base in Zebrach, causing us considerable losses. This German ** officer looked indignant.

"Back then, my father was serving on the submarine, and he died at the hands of this guy, and the hated officer of this guy became bigger and bigger. It is really hateful to dare to offend our Chinese friends now. The other German ** officer also had an angry face, obviously this person hated this Keith very much.

"Now it's time to meet your old enemies, look at me, I will definitely avenge you. And it will also let everyone know that China is not easy to mess with. As long as they dare to offend our enemies of China, we will definitely make them regret it, and they will have a heartfelt fear when they mention China in the future. At this time, Di Wolf looked confident, because he believed in China, believed in the current Chinese National Defense Force, and believed in their principal Chen Shao.

"We in Germany need the confidence of General Di, and we hope that our two countries can go further hand in hand. Now I can't wait to see how the British end. "The second German ** official road.

After casually talking to the Germans, and having made up their minds, Di Wolf ordered the signal corps to turn on the radio and contact the other groups.

The two German ** officers did not speak again, stepped aside, and quietly became the audience.

Other submarine teams also found out, and the other side was bluffing. Because if they did find something, the destroyer would definitely shoot over them and drop depth charges, and now only the sonar sounded, and the ship was gradually moving away. This is obviously not found without being found. So many ships have turned on their radios.

"News from the Bird's Nest that the British fleet is approaching. The eagles will wait for them to get close before attacking. "As soon as the radio was turned on, the news of the aircraft carrier came.

"The enemy ships on the periphery have changed course and converged towards the center." The sonar soldier said to Di Wolf.

The two pieces of news came together, which made Di Wolf couldn't help but laugh.

"God is helping us, just now he praised the other party's commander for having two brushes, and now he is sending us such a big gift, it seems that we can't accept it." Di Wolf said: "Order all submarine groups to approach slowly, keep a distance from each other, and also pay attention to the distance between each submarine." At the same time, the ships were also informed to prepare their torpedoes, and the torpedo firing compartment began to be pressurized. ”

The torpedo itself has power, turning the propeller in the tail of the torpedo to push the torpedo. The launch compartment must be injected with sufficient air pressure before launching, so that not only can the torpedo be fired out of the detonator at high speed during launch, but also the high air pressure can be used to prevent seawater from pouring into the detonator, resulting in the launch compartment being filled with water and unable to continue firing immediately. At this time, the launch compartment was not as advanced as in later generations, and drainage was very troublesome.

There is a barometer in the launch compartment, and if the specified air pressure is not reached, the launch is absolutely not allowed. Because firing under insufficient air pressure will cause the torpedo to not have enough speed to cause an explosion on impact. In some movies in later generations, you will see that after the torpedo hit the ship, it did not explode, that is, because the torpedo was fired too early, the speed was too low, and the impact did not trigger the torpedo warhead, that is, the fuse, so the torpedo did not explode.

"News from the nest that the eagles have begun to attack." Again, the signal soldier said.

Because the submarine cannot see the sky in the water, and the radio of the aircraft cannot directly contact the submarine, it can only be transmitted back to the aircraft carrier, and then the aircraft carrier can be transmitted to the submarine.

"Ordered the ships to begin their ascent, to maintain an attack position 30 meters above the surface of the water, and to maintain a distance of 1,500 meters from the British fleet group. Wait for my command to attack. Di Wolf said.

At a distance of 1,500 meters, Di Wolf is not afraid that the other party's sonar will detect the submarine. He is very familiar with the performance of his submarines, and the attack of the aircraft will also affect the detection. And the position of 30 meters is also suitable for torpedo launch, and at a distance of 1500 meters, as long as the angle of the torpedo is adjusted.

"Order the teams to report on their readiness!" Di Wolf said.

The teams replied that the altitude and distance had been adjusted. As soon as the attack command is given, the torpedo can be fired immediately. After a while, the signal soldier said.

"Ordered each group to fire a salvo of four torpedoes, and immediately after the salvo was fired, a new round of firing was launched, and the second round of firing was to find a target nearby. At the same time, you should also pay attention to the opponent's counterattack, and once you are attacked, you must hide yourself as soon as possible. Di Wolf said.

Just as the signal corps spread the news, the bows of the thirty submarines that had surrounded the British fleet shot out four waves of white air at the same time, rolling up long strings of blisters in the sea.

Once again, the torpedo firing compartment was closed, and with the help of an automatic loading device, the four torpedoes placed next to it were quickly reloaded. A sailor, who was already waiting on the side, pulled down the valve that injected air pressure. After a minute, the barometer needle slowly shifted to the red zone, indicating that the air pressure was sufficient to launch the torpedo at any time.

When launching a torpedo underwater, the sonar equipment of the submarine observes the position and velocity of the target, and then calculates the speed of the torpedo and the speed of the target, and adjusts the attack angle of the torpedo.

There are two types of torpedoes that are standing on hand with merchant-class submarines.

One is an acoustic torpedo that automatically tracks the nearest propeller noise after cruising 400 meters, and this torpedo has a range of 6,000 m/44 knots, 7,500 m/40 knots, and 12,500 m/30 knots.

The other is a passive self-guided torpedo, which is guided by a simple noise detection device, and is designed for attacking ships. The firing range is relatively short, but the speed is high, and the maximum speed can reach 55 knots.

These two torpedoes are not too advanced, and they were already widely used by Germany during World War II, and Chen Shao just let them come out in advance.

This time, in order to deal with the British fleet, it was all this kind of high-speed passive self-guided torpedoes, 533mm torpedoes, once hit, no matter what warship it was for, it was deadly enough. Destroyers of thousands of tons, not to mention, will become scrap metal with one shot. The 10,000-ton cruiser is not spared, and once it hits the hull directly, it can blast at least a large hole of several meters. At that time, it is useless to let more watertight cabins be used, the sea water will continue to pour in, and it will sink sooner or later. However, such a torpedo, if it is against a battleship, it will take at least a few rounds before it can sink a battleship. Not only because of the large tonnage of the battleship, but also because of the thick skin of the battleship, it was difficult to work with only one torpedo.
