The capital, which is full of peaceful atmosphere, is ushering in the midsummer season again. War has become an indispensable part of people's daily lives, but after the war has ceased for a while, people are not used to it. War is the main theme at the moment, and nothing whets people's appetites more than war.

In the president's office in Beijing, Deng Zixuan held a telegram in his hand and a smile bloomed on his face. The war has ceased temporarily, what good news makes Deng Zixuan so happy, it is definitely not ordinary news. Chen Jintang pushed the door and walked in: "The Prime Minister's Office called, the railway laid in the northeast of the capital has been laid to the Shanhaiguan line, and it is currently in trial operation. "Great, just in time Deng Qiang called, our first attack submarine was launched in Huludao. You go and arrange a special train, and tomorrow we will go to Huludao. ”

Chen Jintang continued: "The chief of staff sent a message from Taipei that the Pacific Fleet has been formed, and it is estimated that the three captured battleships will be repaired and added to the ranks in October. "Tell Pei Gejin and instruct Fan Tao to be sure to ask the three battleships to join the Pacific Fleet by November. After the typhoon season has passed, the naval sabotage warfare will continue to be carried out in order to exhaust our enemy from the ground running, and at the same time to create a false impression for the enemy and to create conditions for naval operations in the spring of the following year. ”

The train was running in the field, Deng Zixuan's eyes were staring out the window, but his head was thinking about other questions. According to the original historical records, the American Holland designed the first attack submarine of the United States, but due to underwater air and other reasons, it could not dive for a long time, so it was not put into sea combat.

But history has changed, war is the catalyst, anything can happen. But one thing can be proven. There is no doubt that the foreigners' submarines have not passed the test and cannot be put into actual combat, but the extent to which the submarines developed by the foreigners is unknown. How to compete with the mighty Western fleet. Only by putting submarines into actual combat in advance can we strike at the enemy by surprise and seize the initiative at sea. The last time a French submarine was captured in Vladivostok, Deng Zixuan began to develop submarines. In the past five years, the first submarine was finally launched, which gave the Chinese Navy the capital and weapons to compete for hegemony in the ocean.

In addition, what worries Deng Zixuan is sonar. One of the most effective means of detection in the ocean. Later histories record that sonar appeared in 1906 and was used on a large scale in the First Shijie War. Sonar was first invented by British naval officers Lewis and Nixon. History changes. I don't know if Lewis got the sonar out in advance. This time, the sonar system will be tested with the first attack submarine, and it is unknown how effective it will be at present.

"President, what do you want to be so engaged?" Chen Jintang asked with a smile. Deng Zixuan retracted his gaze and said, "I'm thinking about the submarine that was launched, I don't know what it looks like." I look forward to satisfying the results. Chen Jintang said: "Since the beginning of the year, you have paid special attention to the development of submarines. It seems to be very urgent, and there is no doubt about the concealment of submarines, but can it really play a peculiar role? Deng Zixuan said: "The key to the advantage of submarines is the depth of diving and the time of underwater navigation, if these two conditions are met, we will make the enemy frightened." ”

Deng Zixuan continued: "Submarines were invented by foreigners, and I don't know how far foreigners have developed. But one thing is certain, the submarine of the foreigners did not go into real combat. Therefore, we must be ahead of the foreigners and engage in attack submarine warfare. That's why I'm in a hurry. "President, submarines are so scary. Is there no way to deal with him? Deng Zixuan said with a smile: "Where there is a spear, there must be a shield, and naturally there is a way to deal with submarines." ”

"What's the solution?" Chen Jintang's eyes widened. Deng Zixuan continued: "At the same time as we developed the submarine, we set up a scientific research group to develop sonar. The so-called sonar is an instrument that uses an instrument to listen for sound waves in the sea. Submarines sailing in the water, including warships, emit sound waves. We can detect warships and submarines based on sound waves, and judge their location and distance based on wavelength. If the sonar problem is solved, our fleet will be able to compete with foreigners at sea. ”

"If we master the sound waves, know where the enemy is, and the enemy does not know where we are, our navy will be invincible." Chen Jintang was overjoyed. "But that's wishful thinking, Western technology is more advanced than ours, and they will soon be able to develop a sonar system." Deng Zixuan poured cold water and saw that Chen Jintang was a little discouraged and continued: "Back to the first question, that is, to come out in advance." My goal is that when the submarines and sonars of foreigners form combat power, our navy will be strong enough, and this is the scene I desperately want to see. ”

When Deng Zixuan and Chen Jintang arrived at the Huludao submarine base, the first attack submarine had already been launched and sailed for Shiyan in the open sea. In the research institute of the Huludao Submarine Factory, Deng Qiang explained to a model submarine. The submarine model is very different from the current submarine, the modern submarine looks like a whale, but the submarine in front of you is a ship. The front and rear decks of the submarine were open with a fixed 30-mm gun. There are balustrades on the deck, and the watchtower and entrance in the middle resemble the upper part of a modern submarine.

Frankly speaking, this submarine model is far from the submarine in Deng Zixuan's mind, but there is no way, the current industrial manufacturing capacity cannot reach what he imagined in his mind. "President, this attack submarine is 48.5 meters long and 5.2 meters wide, with a 30-mm fixed cannon on the front and rear decks. The watchtower is set up with a refractive periscope. Built-in air launchers, each carrying three 350-mm high-explosive torpedoes. ”

Deng Zixuan nodded, and Deng Qiang continued: "According to your concept, the president uses a 24-kilowatt diesel engine to drive surface navigation, and the cruising capacity can reach 1,000 kilometers. Underwater navigation uses a battery that can go unsurfacing for eight hours in a row. The submarine is 15 meters deep and has a crew of 14 people. These are theoretical data, and at the moment the submarine is shiyan in the sea, and how effective it will have to be tested in order to draw conclusions. ”

Deng Qiang continued: "President, after four years of continuous public relations, the sonar instrument was loaded on the submarine for the first time, and theoretically the sonar can detect ships and underwater submarines within 20 nautical miles, and the underwater preliminary shiyan can also reach the theoretical data." But loading on a submarine still needs to be repeatedly checked. Deng Zixuan said with satisfaction: "Very good, with a good haode start, you can have fruitful results, when will the Shiyan submarine come back?" "I've been out to sea for two days, and I'll be back tomorrow morning!"

The sunset reflects the Bohai Bay, and the sea surface reflects the ripples of gold. Deng Zixuan and Chen Jintang climbed high and looked out, and the vast picture on the sea was refreshing. "You see, Huludao stretches out to the Bohai Bay, it really looks like a gourd floating on the sea, and the scenery is very beautiful." Deng Zixuan couldn't help but admire. Chen Jintang was infected by it and said: "Huludao is worthy of being a natural harbor, and the great rivers and mountains of the empire are so beautiful that you can like it no matter how you look at it!" ”

"Brother Chen, in the future, Huludao Military Port will be built into the largest submarine base in the empire, and in the future, our powerful submarine fleet will set off from here to fight in the ocean, and the day when the Chinese Navy will be alone in the world will not be too far away." "President, the day you are looking forward to is coming step by step, does it feel like you are dominant?" Deng Zixuan said with a smile: "The result is not important, the important thing is the process." In the process of pursuit, you can experience the greatest happiness. ”

"President, you have said a philosophy, often after glory, there will be a trace of melancholy, but in the process of pursuing glory, that joy and excitement are worth remembering, and I deeply feel this." "Yes! Our generation is explorers, and it is only in the process of exploration that we can feel the true meaning of life. I'm in a good mood tonight, why don't you and I have a drink? "So what are we waiting for?" The two of them tacitly and happily.

The next morning, when the veil of dawn was lifted and the twilight was lifted, Deng Zixuan and others appeared on the dock of Huludao No. 1 Military Port. Many admirals craned their necks and looked into the sea, no one made a noise, everyone waited quietly for that moment. Suddenly, there was a swell on the surface of the sea, and the water was churning, and in the blink of an eye, the watchtower of the submarine came out of the water, followed by the deck and the hull. The submarine shook the sea water on its body and slowly approached the shore.

After a while, the captain came out of the entrance, and so did the scientists involved in the experiment. Seeing that the scientific researchers were very young, Deng Zixuan was extremely happy. What's most important? Talent is the most important thing. Nowadays, a large number of young scientific research troops have formed scientific research teams on all fronts, they are young and energetic, dare to think and dare to do, and do not conform to the rules.

Deng Zixuan shook hands with the young scientific researchers one by one, and encouraged them to make persistent efforts, bravely climb the peak of science and technology, and make greater contributions to the Empire's naval cause. "What's your name?" Deng Zixuan Zuihou held the captain's hand and asked cordially: "Report to the president, Major Yu Haiyang salutes you, please instruct!" "Yu Haiyang, you are the captain of the Empire's first attack submarine, do you have the confidence to sink the enemy's warship?" "Report to the president, with confidence." Deng Zixuan said loudly: "Now I announce that this attack submarine is named Hailong No. 1. The crowd burst into cheers.

At the submarine base command, Deng Qiang once again reported: "President, the first stage of the submarine Shiyan, surface navigation for 50 consecutive hours without obstacles, underwater navigation for 6 to 5 hours, and deep diving of 14 meters, there is a gap with our theoretical data. Deng Zixuan said with satisfaction: "Very good, after the second and third phases of shiyan are finished, I think I can consider the installation." What projects will be carried out tomorrow? "It's the highlight, the submersible torpedo attack!" Deng Qiang said.

"This is the most critical performance of the submarine, all the data is up to standard, and if the attack is greatly discounted, the submarine is gone." "The target ship is a medium-sized wooden steam freighter, and unfortunately there is no steel ship as a target." Deng Zixuan said with a smile: "Wooden boats can also test the effect of experiments. The next day, an hour after the submarine dived, it launched a torpedo attack 100 meters away from the target ship, and the torpedo accurately hit the target, and the explosive power of a torpedo shattered the wooden target ship of more than 600 tons, and initially achieved the Shiyan effect.

Before leaving, Deng Zongxuan instructed that after the completion of the submarine Shiyan, if there is no major improvement, it will be put into mass production, and strive to form a 10-submarine fleet in the spring of next year. As for the upgrading and improvement of submarines, they have been constantly tested and improved in actual combat. On the train, Deng Zixuan told Chen Jintang that with the submarine force, the Nanyang strategy began to be implemented, and it was time to wake up Lan Fang. (To be continued......)
