…… Under the sky of resale, Yan is a large-scale, factory. A few towering sparks of black smoke billowing from the four skies. From time to time, the sound of the steam engine sounding from time to time, intertwined with the sonorous sound of the forging press. Play a symphony of the industrial age.

This is a branch of Wuhan Shipyard, located downstream of Wuhan. Immediately next to the Yangtze River, it's the start of the factory's opening day, and the entire factory can be seen busy with workers and technicians, sparks flying in the tall dry docks, and welders busy working. There was a strange smell that filled the scene.

Due to the relatively high terrain here. From the ships sailing on the Yangtze River, you can't see what's going on inside the shipyard. The nearby mountains were also military exclusion zones, so it was not easy to figure out what ships were being built in this shipyard.

In fact, even many of the workers working in the dockyards did not know what kind of ship they were building, and only a few technicians could give such ships an official name: submarines.

Unlike the near-shore alert submarines built by the Gaochangmiao shipyard in Shanghai, the shipyard in Wuhan made an ocean-going attack submarine, and it is especially worth mentioning. This submarine is not exactly a copy of the German ocean-going submarine. At the beginning of the design. The German shipbuilding technologists who were in charge of the design work took full account of the special requirements of the Central and Admiralty.

In fact, to be precise, it was a special request from Mr. President, who personally told these German shipbuilding technical experts. This new ocean-going attack submarine must have better underwater endurance and longer range. In order to meet this design requirement. German shipbuilding technologists had to find ways to put more and better lead-acid batteries in the bilges of such submarines. to ensure better underwater endurance and longer underwater range.

Originally, this design was very demanding, how to put more batteries in the submarine without affecting the submarine's sailing performance, which was a test in itself, after careful calculations and bold attempts, German shipbuilding technology experts widened the hull of the submarine. The broadside height is raised. And the length of the hull was appropriately lengthened, so that it came. You can install more batteries in the hull. In order to ensure the endurance of underwater navigation, and in order to save space in the boat as much as possible, shipbuilding experts have reduced the number of crew members, and more importantly, in the later improvements. They used the fuel injection mechanism of the improved diesel engine to modify the old bulky diesel engine, which reduced the size of the power compartment by nearly a quarter. All the space saved is also given to the battery pack.

As a result of the design of this new ocean-going attack submarine, it was finalized in the state rhetoric. Therefore, it was officially named the "Old Mouth Ocean Attack Submarine" by the Admiralty and was all built by the shipyard in Wuhan. Nine ships have been built, two of which have been completed and delivered to the Navy for service. Commanded, Shuai Tang was named "Shark" and "Dewfish" respectively, and the remaining seven are currently close to completion, because the submarine of this type in service is "Shark Concubine." Number. Therefore, this ocean-going attack submarine is also called the "Shark-class ocean-going attack submarine" by the Commander-in-Chief

This ocean-going attack submarine is quite combat-ready. For example, the former boat "Shark", which has a surface displacement of the boat. The underwater displacement is only a ton. There were six torpedo tubes and four boats. There are two stern torpedoes, and a total of eight torpedoes with a diameter of 450 mm are stored in the boat; due to the use of two heavy diesel engines as power, plus the flying shear type ships, the surface voyage of the boat has reached 17 knots, thanks to the original German high-power electric motors, the underwater navigation degree of the boat has also reached 9 knots, and if it sails on the surface at five knots, the range of the "Shark" can reach 4,000 nautical miles.

Theoretically. The technical indicators of the Shark-class submarine have reached the international first-class level. Although the submarine was designed by the Germans, its construction was done in Chinese shipyards, and most of the shipbuilders were Chinese workers, either way. These ocean-going attack submarines are all authentic Chinese goods. It is the top masterpiece of China's industrial technology in this era.

Knowing this, it is also possible to understand why Zhao Bei is now wandering around the shipyard. As the head of the country, he had every reason to come and see the factories and workers who made the advanced weapons of war, not to mention his contribution to the design of such ocean-going attack submarines. Flying scissors boats, amazing capacity of the battery compartment are his suggestions, or his requirements and orders, these historical experience is indeed very conducive to the realization of technological leaps, without Zhao Bei's suggestions and orders, perhaps this kind of submarine still can not get rid of the image of the French and German submarines.

In fact, German shipbuilding experts have also gained a lot of useful inspiration from this design work. The merits of the "Shark" were quickly summarized and reported to the German General Staff, and the German Navy even changed the orders that had already been placed for the shipyards. The shipyard was asked to immediately revise the design, to make sure to build a better submarine for the German Navy, and, of course, another side. Germany still hasn't really paid attention to the Submarine Department VI: Plant II. The German Navy was still obsessed with the construction of battleships. After all. The new naval warfare weapon of the second and sixth hearts of the submarine has never been tested in actual combat, and how much effect this underwater weapon can wield, except for Zhao Bei, I am afraid that few people in this era can say clearly.

In Zhao Bei's mind. This submarine is the real underwater killer, as its name suggests, the shark, which devours all its prey without mercy.

On the other hand. Zhao Bei was building submarine troops at the same time. It is also necessary to avoid giving enlightenment to Japan. Avoid the Sea of Japan shrug your attention to submarine warfare.

Since the Germans despised the strategic value of submarines, the Japanese, of course, did not attach importance to this new type of naval warfare weapon. In order to avoid irritating the nerves of the Japanese, Zhao Bei took advantage of the situation to formulate a strategic deception plan, and through a series of actions, the Japanese mistakenly believed that China's submarine force construction was focusing on coastal defense. At the same time, in order to further confuse the Japanese government. The Military Intelligence Bureau launched a series of anti-espionage operations, which not only destroyed a number of Japanese espionage organs in China, but also dug up a number of "rat-destroyers" from the Ministry of the Navy, the Ministry of Heavy Industry, the Ministry of Industry and Commerce, shipyards, and other departments, effectively guaranteeing the implementation of the central strategy.

But. China in this era. Society is full of holes. Zhao Bei was not absolutely sure that the news would not be leaked, so he had to urge the shipyard to complete the construction of the remaining ocean-going collection boats as soon as possible, so that they could join the naval forces as soon as possible, in the event of a war between China and Japan. These submarines will be fully functional.

In view of the strength of Japan's navy, it is far from enough to rely on these submarines built by China itself, so starting last year, the central government did not hesitate to allocate huge sums of money to order several ocean-going attack submarines from the United States and Austria-Hungary, which are now nearing completion, and once these foreign submarines return to China, the strength of China's naval submarine force will be greatly increased.

Originally, Zhao Bei also planned to order several submarines from Germany. But Germany is now stepping up to build warships for its own navy. Considering that the principle of warfare against Japan formulated by him is that the "war decision" will not drag down the development of China and China, therefore, as far as the current shipyard capacity is concerned, it may be too late to add a new ocean-going submarine construction plan, so before the outbreak of the Sino-Japanese war. It is impossible for the submarine forces to get more ocean-going submarines.

Right now. Zhao Bei has decided to devote the main energy and funds to the manufacture of tanks, not only the tractor factory will immediately switch to the manufacture of tanks, but once the construction of these nine ocean-going submarines is completed, some of the skilled workers of the shipyard will also be immediately transferred to the tractor factory. Help make the "King of 6 Wars" after all. The main battlefield of the two sides is on the land, and the maritime battlefield is not a stable battlefield for China.

According to Zhao Bei's strategic calculations, this war will be decided by the victory or defeat of the battlefield on 6. As for the ocean battlefield, it is only attached to the 6 upper battlefield, but this is not to say that the marine battlefield is not important, if China's diving micro-captains can hunt one more prey on the ocean battlefield, then, the military pressure faced by the Chinese 6th Army on the battlefield will be reduced by one more point, and if China's 6th Army can fight a decisive battle, then, China's navy will be able to preserve its strength to the greatest extent. And look forward to the arrival of that real "naval age".

Although the working environment of the dockyard was very harsh, Zhao Bei still stayed here for almost one. hours, talking with technicians and workers, and of course, with those German technical experts. These Germans not only designed an ocean-going submarine of their own for China. And a new type of high-altitude destroyer was also designed for China. In addition to the small fast warships being built in the docks of the Fuzhou shipyards, these German shipbuilding experts are designing a new, simple and standardized cargo ship on the orders of Zhao Bei, and a common, standardized dock and shipbuilding specifications for all shipyards in China. Once the design is complete, Chinese shipyards will be able to standardize the batch construction of the same type of ship in the same way as automobiles, which can greatly improve the shipbuilding capacity of Chinese shipyards.

Surrounded by the attachés. Zhao Bei walked through the construction site composed of rivets, steel plates, acetylene tanks, stoves, scaffolding, and sleepers. This atmosphere of the industrial age fascinated him. It's almost impossible to extricate yourself. He is not a proud person, but whenever he sees every step of China's progress in industrial construction, his heart is always filled with a kind of pride of "who else can I be", in his opinion. The reason why China has been able to achieve such jaw-dropping industrial progress in just four years is the result of his single-handed promotion, and he is the soul of the country's initial industrialization. Without his crossing, perhaps the country would have waited many years before it reached the threshold of industry.

But now, Zhao Bei has traveled to this era, then, the future of this country will definitely be rewritten because of him. Zhao Bei firmly believes in this.
