The first 8 submarines Bai Shujie saw seemed to be 8 tanks floating on the water, and he immediately remembered that this was a British P-class submarine. The bridge of this submarine looks like a tank no matter how you look at it.

The P-class submarine has a crew of 54 people, a depth of 95 meters, a displacement of 1,475 tons on the surface and 2,040 tons under the water; It is 88 meters long, 9 meters high, 4.16 meters draft, 4600 horsepower above water, 1350 horsepower underwater, 17.5 knots above water, 9 knots underwater.

7,300 nautical miles for 10 knots on the water and 60 nautical miles for 4 knots underwater; The 533mm torpedo launcher has a front 6 rear 2 layout, 1 133mm main gun, 2 7.7mm machine guns.

Bai Shujie is not interested in this kind of thing. Because the life of this submarine was not good, the construction of which coincided with the global economic crisis, and the British Navy simply did not have time to equip it.

As an intelligence officer, Wang Xinlan was able to discover the huge role of the submarine, and she fell into the ground and bought the British submarine back, which is commendable.

However, Bai Shujie was not interested in the power system of this submarine. Because the British saw an English Channel, their submarine engines were designed to be problematic and the range was too small.

However, Bai Shujie still can't take care of this problem, and when Meng En figured out the engine of the helicopter, these eight submarines need to replace the power system and install sonar detection equipment.

What Bai Shujie is concerned about is what the products made by the Germans will look like after the "submarine giant" was changed according to the little devil's later development.

It turned out that there were no real submarines at all in this era, and the name of the little devil was more reliable - a submarine. That is, warships capable of diving underwater.

Since it is a warship, it has the appearance of a warship, with main guns, secondary guns, and machine guns. Because of this, when Bai Shujie saw the British P-class submarine for the first time, he thought that 8 tanks had fallen into the water.

After looking at it for a long time and not discovering what he designed, Bai Shujie was a little strange: "Why haven't we seen our own new submarine?" ”

"It's in a sheltered harbor to the east, and it's hidden in a repair dock." Zhang Bingyang shook his head: "Those guys who stayed in the ocean and came back, none of them left. I heard that the Germans have a rule that this submarine must be used in secrecy and cannot be made public. ”

Under the leadership of Zhang Bingyang, Bai Shujie crossed a corridor and finally came to the covered maintenance dock, where 5 big black fish were pulled into a long slip and quietly docked at the edge of the still water dock.

"Report to the commander-in-chief: Lu Yunlong, the deputy captain of the cadet group, led 5 new ships and 609 cadets back to the base, please instruct!"

"Okay, good, brothers, hard work!" Bai Shujie said loudly: "If you go out to study for a year, you will be able to cross the three oceans and drive our submarine back safely, you are all heroes of the Flying Dragon Expeditionary Force!" Now, could you please tell us about your new ship? ”

"Report to the Commander-in-Chief, Commander: This submarine of ours adopts the world's most advanced teardrop-shaped shape, which greatly weakens the resistance of sea waves and sea water. Not only can it increase the speed, but it also reduces fuel consumption as much as possible. ”

"The new rubber tile cover effectively insulates noise and reduces the possibility of being detected by the enemy, and the streamlined double-hull design allows it to be in the cold and deep sea. The continuous combat capability reaches five months, and the combat radius can reach any corner of the world. ”

"It is 122.3 meters long, 9.6 meters high, 7.02 meters draft, 29 knots on water, 13 knots underwater, 33,000 nautical miles in 20 knots, 39,500 nautical miles in 14 knots and 80 nautical miles in 7 knots. The maximum diving depth is 120 meters, and the safe diving depth is 100 meters. ”

"3,530 tons of water displacement and 6,750 tons of underwater displacement; 4-seater 2-axle diesel engine with 9,600 hp; 2 x 2,400 kW generators; The total number of personnel is 176. ”

"The armament consisted of one 140mm 50x deck gun stern at the stern, one 40mm anti-aircraft gun on the conning tower, and three triple 40mm anti-aircraft guns above the hangar. There are 8 torpedo tubes in the bow of the boat, and 36 ammunition are in reserve. ”

"Looks like you're familiar with each other, yes, yes." Bai Shujie applauded and smiled: "How about it, after this voyage, have the brothers mastered all kinds of operational essentials?" ”

"Report to the Commander-in-Chief: As soon as you give the order, we will be able to attack immediately!" Lu Yunlong said loudly: "Since we saw this new type of submarine, we have admired the commander-in-chief's genius in our hearts. The German classmates all say that we have a genius commander-in-chief! ”

Speaking of this, Lu Yunlong was a little embarrassed: "However, I always have a question in my heart. I want to ask the commander-in-chief in person today, but I don't know whether to say it or not? ”

Bai Shujie scolded with a smile: "If you have a fart, let it go, you will be born after a year of fucking going out, how can it be justified!" ”

"That's right." Lu Yunlong said seriously: "When we were studying in Germany, we were specifically responsible for supervising the manufacture of this latest submarine. But the Germans referred to the drawings, but made a big modification, that is, 3 water bombers were added. ”

"I want to ask, why didn't the commander-in-chief adopt this approach? With such a large carrying capacity of this new submarine, wouldn't it be a great increase in our combat effectiveness if we had three bombers? ”

Bai Shujie also said very sternly: "Good question! Brothers, I know that Lu Yunlong is here to inquire on your behalf, and I am glad that you have such questions, which shows that you have not studied in vain, but have thought about it seriously! ”

"For the strategic thinking of submarine operations, I am different from others! This difference is reflected in the fact that I did not design an open hangar, and the whole submarine is a sealed whole. ”

"So, what is the use of the huge space that has been left and the rich displacement of 25 tons? This is the core of the problem, and it is also my future combat demand! ”

"You know, in our Wyvern Expeditionary Force, there is a mysterious unit called the Special Operations Brigade, right? Then, our future Flying Dragon Navy should also have its own special operations group. This special operations brigade is none other than you submariners! ”

"I don't need you to fight the enemy face to face on the water, and I don't need you to use carrier-based aircraft to bomb the enemy, because that's the matter of naval aviation, so I didn't equip you with bombers."

"And you should know that even if you have bombers equipped, you can only use a suicide attack, because you can't take back the planes that you let out. And the range of this seaplane is too small, it simply cannot find where its aircraft carrier formation is, and in the end it can only fall into the sea. ”

"From today on, you have to remember to Lao Tzu: you are the ghost killer in the depths of the ocean, and it is best to let the people of the world never see you! For those who see you will eventually become dead! ”

"At the moment these submarines are not yet operationally capable, because I have not yet installed radar and sonar systems designed specifically for you. If you want to be a ghost killer in the depths of the ocean, you need to be able to detect each other before your enemies. ”

"Therefore, the first role of the rich space is to install two monitoring systems, plus a fire control system. So that you can fire the first torpedo the moment you spot the enemy. ”

"The two systems weigh less than a tonne, which has no effect on the rich displacement of 25 tons. That's your second mission: a submarine capable of delivering a company, 226 marines and full equipment to Lao Tzu! ”

"You're fucking short-legged generals, and you can only stare dryly at the landing, so you need Marines to cooperate with the battle. These Marines are training in secret, and when you come back, you're going to start training together. ”

"We will have a total of 10 such submarines at that time, that is, we can send 10 companies overseas, that is, a regiment of 2,260 people. For this reason, your commander Zhang Bingyang trained two regiments of 4,600 marines. ”

"After consultation with your Commander Zhang, the submarine group under the Feilong Navy Command is now officially formed, which is at the regimental level. Captain Gao Shengkui has not returned to Germany yet, and Deputy Captain Lu Yunlong is temporarily in charge of the command and training of the entire brigade. ”

"We now have a total of 5 DW Ghost 1-5 ships, 8 DW Shadow 1-8 ships, and 3 DW White Shark 1-3 ships, a total of 16 ships. All of you, the 609 people who have returned from studying abroad, are now taking over these submarines. ”

"While the shipyard is being renovated simultaneously, you must familiarize yourself with each other's performance and find the entry point for coordinated operations. In view of the various changes in the enemy situation that may occur, various contingency plans have been formulated. As for how to coordinate with the surface fleet, your Commander Zhang and Deputy Commander Ge will continue to study with you. ”

After a banquet in the cafeteria of the Jiaodao Naval Base, Bai Shujie returned to the headquarters, but it was empty. Later, when I went to the telecommunications office, it turned out that the girls had gone back to listen to the old man's travel stories.

Bai Shujie did not go back, but began to think about a new problem, that is, his submarine group has begun to take shape. It's equivalent to the fighters having guns, but not bullets yet. Hand-to-hand combat without bullets is not allowed.

Therefore, Bai Shujie wanted to copy a high-powered torpedo. The launch canister 533mm is already OK, there is no need to make it too thick, although some people like to be thick, but they don't know that the thicker the better.

Bai Shujie now has a lot of 533mm torpedoes in his hand, each of which is 1.2 tons, about the same size as a 406mm shell, and his heart is numb when he sees it.

And there are also a dozen "oxygen torpedoes" of little devils, 610mm, which is even more terrifying. And it's too dangerous to put it nearby, so Bai Shujie is trying to find a way to destroy it. The destination of the destruction is likely to be airdropped to Wonsan Fortress by plane!

Bai Shujie calmed down and began to draw. Now that so many precision lathes are back, the conditions are ripe for torpedo improvement.

In order for Bai Shujie to re-produce his own torpedoes, he needed to solve four problems:

First of all, it is the torpedo engine that needs to be improved. Increase power while reducing volume and weight. Saves weight and space, increases the amount of charge. This problem can only be solved by the Jews, and Bai Shujie only has to raise the problem and ask for improvement.

Secondly, improve explosives. Safety must be ensured at the same time as a significant increase in explosion yield. In particular, submarine torpedoes must have a sufficiently large safety factor. The brushless motor does not generate sparks, making it particularly suitable for use and storage in explosive locations.

Thirdly, there is a need for further improvements in the guided magnetic detector. Increase the detection range while increasing the sensitivity.

Fourth, Bai Shujie was very dissatisfied with the fixed-depth control system of air-dropped mines. The mines of this era were so bad that they had little technical content.

After all, what happens next, let's see how it will be broken down next time.
