I said, Mr. Holland, when will your submarine be able to get my troops?" asked Wang Desheng, commander of the Sea Wolf Force, in the submarine base.

"Don't worry! Commander Wang, you will be able to try it out soon!" Holan said.

Since returning to the base, Wang Desheng's sea wolf troops have become landslides. Although the submarine achieved surprising results in the battle of the Yellow Sea, many problems have been exposed, such as the need to float up during communication and erect a long antenna pole. After the person hits his own people underwater, the damage pipe protection system cannot bear it at all. They were noticed by Holland and Lake, so they were all sold to the UK and Germany after simple repairs.

After research and demonstration, the two of them had strengthened protection for the command room, ventilation pipes and power chambers, in addition to using the double-hulled hull. For communication issues, Holland adopted Lake's suggestion to set up an antenna outside and change it to vertically lifting and lowering from the increased command room, so that the submarine can communicate with the coastal outpost or fleet through the lifting antenna at a certain depth.

Although this solves the complex problem of liaison work, it also brings new technical problems.

After a certain depth, radio communication cannot be contacted. For this reason, Holland designed a towing antenna ingeniously, which solved the submarine's underwater communication problem, but new problems also emerged. Towing antennas require huge winch space. For current small submarines, the space inside the submarine is hard to buy.

Amplification has become the bottleneck of Holland and Lake breaking through the small submarine ground. However, after amplifying the existing submarine, the tonnage is increased. In order to maintain the degree, the required internal combustion engine and electric motor must increase the power, so that the reaction space will be returned and it becomes a vicious cycle.

Finally, Zhang Yunfei's electric order solved this embarrassing situation. In Zhang Yunfei's view, the current submarine level and surface ships are too big, and this gap will become bigger and bigger with the emergence of steam turbines. Then, using submarines to fight cannot compete with surface ships in terms of degree. The mission of the submarine land makes it only a shark lurking in the sea, waiting for the prey to come to his door.

Since Zhang Yunfei no longer requires the degree of submarines, there is no obstacle or consideration for Holan's submarine amplification design.

The shark||| submarine is the product of this kind of idea. The standard underwater displacement of this type of submarine is 1, which is more than twice the original two submarines, and is nearly thirty meters long, reaching 60 meters. The double-layer shell technology and the new pressure-resistant and corrosion-resistant special steel make the hull solid and firm, and no longer cause minor collisions to cause serious damage to the hull.

With much larger space, many sets of power systems are naturally arranged. Rudolf-Diseldiel's latest Diesel-Disel-type diesel-powered compression ignition motor is adopted. This motivation has a large power, low fuel consumption, and low quality fuel can be used. This reduces the burden on the Honolulu petrochemical factory. After simply filtering the oil, it can be used. With a large space, it will be more air to be stored.

The vent pipe device is a pipe that can lift and lower the ground. When sailing in offshore waters or at night, the submarine sometimes floats to the depth of the periscope. At a place that is several meters or ten meters deep from the water surface, it extends out the periscope to observe the enemy situation on the water surface. If conditions permit, the vent pipe can be lifted out of the water surface. The air can enter the submarine compartment through the pipe. The dirty air in the cabin can be discharged by an exhaust fan installed at the rear of the podium enclosure. The air in the boat can be convection and fresh air can be maintained.

Periscope depth is called dangerous depth in tactical terms. For the sake of concealment, submarines generally do not dare to use this working state because they are very likely to be exposed by enemy anti-submarine forces. They are easily impacted or disrupted fishing nets in the near sea. However, according to the analysis of the Honolulu Naval Area Operations Sea Area, submarines basically move in the deep sea. Therefore, this class of submarines are equipped with long snorkel devices.

The Diesel-type diesel-motored underwater output power of 180 force. It can drive the submarine to sail at 9 junctions for 3,500 miles. The endurance is more than a little slower than the original submarine. However, it is equipped with torpedo tubes, two in front and back. There are 16 torpedoes. The officers and soldiers have made it a veritable deep-sea hunter.

"Mr. Holland. Although our new submarine looks big and strong, it's too low! How to fight!" Wang Desheng asked.

"Commander Wang. Although our submarine has decreased a lot, its survival ability has increased by more than twice. When facing enemy attacks, the chance of surviving is much higher. Moreover, there is currently no submarine warship in the world that can specifically deal with our submarines. In the deep ocean, we are the king." Holland said proudly.

Wang Desheng asked in confusion: "But we are so slow, how can we catch up with the enemy's warship? I'm afraid we can catch up with the transport ship at most!"

"That's right!" said Lake, who was standing by, "Your Mr. Yuan Zhang's submarine warfare theory is very correct. Since the submarine cannot improve in a short period of time, you must adopt other tactics to adapt to local conditions to the submarine's role. We cannot catch up with the enemy's warships, but we can ambush on the scheduled route.

Judging from the current military situation of our submarines, if operated properly, the number would be enough to sink a small fleet."

"Even if you cannot attack enemy warships, you can still attack passing merchant ships and transport ships. The strategic significance is no less than that of your attack on enemy fleets!" Holland added.

Wang Desheng shook his head and said, "Let me be the commander of the Sea Wolf Force attack the civilian ship?"

Facing Wang Desheng's questions, Holland and Lake looked at each other and smiled and walked away, leaving Wang Desheng thinking about the problem alone.

Just when Honolulu was reforming its new submarine, it was also conducting submarine tests in a secret base in Germany far away in Europe. However, even the German side was not very clear about these things, and Zhang Yunfei certainly could not obtain information. In fact, it was not difficult to guess that the German submarine suddenly appeared during World War I and fought a fierce unlimited submarine war, teaching the Allies a lesson. The performance of its submarines was the leader and was destroyed by a large number of American destroyers until the end of World War I. It can be seen that the German U-type submarine was advanced.

Without quantitative accumulation, there will be no qualitative leap. This is a common truth. Zhang Yunfei secretly displayed his submarine himself, so on the other hand, other countries naturally have many secrets, and Germany is one of them.

As early as the beginning of 185, Germany began to build submarines, hosted by the Ming family Wilhen Bauer (i1hhe1mmbauer). At that time, the submarines, as a new naval thing, had attracted the attention of some visionary politicians and military strategists. Although Germany did not think that the submarines at that time were very important, this did not affect the attention of the German scientific and technological research department.

The early research on submarines in Germany was slow. It was not until 1890 that Nordenfert designed the secret trial of submarines of 11 and 2 that attracted the attention of relevant German departments. Although there was strong support, the top military leaders did not think it was very powerful and practical. At the same time, William II was carrying out the Navy plan and following the path of giant ships and cannonism, he ignored the existence of submarines.

However, the sound of artillery fire in the first battle of the Yellow Sea in China and Russia made the keen Germans notice the practical significance of submarines. At the same time, France's exercises once again showed the huge role of submarines, so Germans turned their attention back to the long forgotten German submarines.

Fortunately, although the German submarine was forgotten, there was no fault yet. It was just progressing slowly. It also built its own "Karpp" ('karpp'), the U-11 class submarine. It has a double-hull structure and powered by a Kotine-type kerosene engine, with only one torpedo tube.

Subsequently, the Germans obtained advanced technology from Zhang Yunfei. After transformation, they immediately started to build the next-class submarine, the U-2 class, which was half larger than the original size and had two torpedo tubes. However, the Germans did not agree with the appearance of the shark-class submarine in Honolulu and believed that it was flashy. Since the submarine was an attack ship, it should have counterattack ability. Therefore, the Germans prefer French submarine designs, and equipped small fire cannons and heavy machine guns outside the submarines to attack the enemy.

The French missed the importance of the aircraft master Adel, which made Zhang Yunfei take advantage of the loopholes and go to the forefront in the field of aircraft. However, the French were always keen on the navy. It was also a new thing, but the submarine did not follow the old path of aircraft and received additional attention from the French government. In 1893, the French Navy "Gustav-Zid" submarine was launched. It had a displacement of 266 tons and used electric motors to drive the propeller to push the submarine forward. This was the most advanced submarine among all countries at that time. On November 5, 1897, the "Navier" submarine designed by French scientist Laubev was launched in France. All of this made France not lag behind Honolulu in submarines, and even many places were far more advanced than Honolulu's submarines, mainly because France had strong industrial support.

However, the Germans and French were not that far-sighted. Not only did they install artillery systems on the submarines, they even imagined that they would build an underwater battleship. The huge inertia of history was inevitable, so Zhang Yunfei naturally wanted to accept that the Europeans would take more detours.

However, after the Germans obtained Zhang Yunfei's technology in advance, the U-type submarines in history appeared in advance. Moreover, the submarines were tested in the Yellow Sea Battle, which prompted the Germans to focus on the submarine exhibition too early. Zhang Yunfei could not grasp the impact that would have in the future.

Germany and France's emphasis on submarines made the British uneasy, but the British's status as the world's largest naval power cannot be shaken by a few submarines that steal. The British Admiralty, with a gentlemanly demeanor, just barely perfunctory the members of Congress, and they were too lazy to build submarines.

Fortunately, Zhang Yunfei, the assistant, was exhibiting submarines, so he only purchased a batch of submarines in Honolulu, and then he got it done.
