In the early morning, the sun rises in the east, and the cold wind and snow condense. At the Ninhagen shipyard on the southern shore of the Baltic Sea, a strange ship slowly slid from its slipway into the sea, bursting out with a large white splash. Unlike other surface ships, it was put into service directly after launching, without any outfitting work; A black vulture navy cross flag is raised on its freeboard, which is only 0.4 meters high, and the hunting flutter has a unique meaning.

On the viewing platform at the top of the slipway, several figures in gray coats stood near the sea, looking intently at the ship not far away. At 30 meters long and 3.2 meters wide, it is compact and slender, and most notably, it has a single conning tower on deck that can only accommodate one person, and nothing else.

"Mr. Khedira, I remember you told me before that it only takes one and a half years for this submarine to be able to make a finished product. But today is February 15, 1898, and nearly two years have passed since the day you made your promise. ”

With a sound like a jade-like sound, the figure standing in front of him turned his head; The brim of the hat was slightly raised, revealing a handsome white face. An ordinary military coat was worn on his long body, and there was a dazzling look of abundance and jade. Hearing the young man's words, the man standing on his left coughed a little embarrassed and said, "Back to Your Highness, this is indeed a little simple that I thought about at that time. I originally thought that it would only be necessary to solve the problem of the submarine rolling and pitching under water, and then install an engine to complete it; Unexpectedly, after this, some other factors were involved, so that the workload surged. By the time I had all the problems solved, it was November of last year. ”

"Speaking of which, little Khedira, you guy who delayed building it for more than 4 months can't be a thing that can only be seen but not used, right? In order to overcome the water pressure experienced by submarines when navigating underwater, special pressure-resistant steel is required, and the cost of this thing is comparable to that of a high-power power system. If the Navy were to come and buy the 130-ton little guy, it would take at least 280,000 marks to tow it away. If your work fails, even if you work for the rest of your life, you won't be able to repay Your Highness's investment. On the right side of the boy, a middle-aged man with one-sided glasses said in a slightly teasing tone.

"Shut up, Flick, how can you understand this cute little toy I designed by lowering the freeboard to improve performance?" Originally, Khedira was still standing in front of the boy with a guilty face because of the delay in the construction period, and when he heard this, he immediately jumped up like an enraged bulldog. He looked at his old partner's hateful toothy face, and said angrily: "Today is the time for this submarine to go on trial." You give me a good look, and if anything goes wrong with it in the process of forwarding, turning, diving, ascending, and torpedoing, I'll cut off my head and eat it again! ”

The boy was sandwiched between the two, slightly embarrassed. At that moment, a group of naval officers and men in straight uniforms stepped out of the front corner and ascended to the deck through the wooden bridge that went deep into the berth. Seeing this, the two involuntarily withdrew their annoyed or playful glances at each other, and refocused their attention on the submarine in front of them. Due to the cold weather, the officers and men wore thick winter coats, and the speed of entering the submarine appeared to be exceptionally slow; After a while, the team of about 10 officers and men entered the submarine through the opening in the center of the control tower, and one of them worked hard for a long time because of his strong physique.

Seeing this scene, the young man's sword-like eyebrows couldn't help frowning slightly. Fortunately, a moment later there was a rumbling sound; Listening to this uplifting voice, the young man's mood turned to anti-expectation. After nearly 2 years, he also made a submarine belonging to Germany; Although this speed is still more than half a year later than that of the American Horan, as long as there is a great support from his own traverser, Germany's attainments in this field will definitely be far superior to other powers!

The mechanical vibrations, the sound is deafening, and even in this windy weather, the roar of the gasoline engine still spreads far away. The propeller behind the submarine began to rotate slowly, from slow to fast; After a few moments, the entire barracuda-like hull shook slightly, and then began to sail offshore. The waves are flying, and the flag is hunting. Every once in a while, the submarine has to increase its speed slightly, and when it reaches its peak, it is already like a swimming fish cleaving the waves on the sea, sailing smoothly.

Suddenly, the port side of the submarine collided with a large number of surging water, Qingying's heart was slightly cold, and she knew that this was the rhythm of the ship that was about to turn. Before the thought could be lost, the barracuda tilted its bow and drew a smooth arc of water waves on the sea. Qing Ying stared intently at the blue sea below him, nervous in his heart, and his hands involuntarily clenched into fists, for fear that this submarine would be unhappy, so he would give him, the crown prince, his side-flipping stunt.

The clock ticked, and the beating atrium beat Qingying's chest one by one. Seeing that the submarine completed a 180-degree turn in an extremely stable attitude, the water splashed and the aftermath was faint; Qingying's heart finally landed on the ground, and she couldn't help but breathe a sigh of relief. He turned his head, faced the cold wind blowing in his face, and said with a smile to the two: "It seems that the water navigation performance of this submarine is indeed very superior!" Mr. Khedira, how did you do that? ”

Khedira was very proud to see that the submarine did not show any signs of shaking or jerkiness, whether it was whirling or turning left and right. Hearing Qingying's slightly approving inquiry, he glanced at Frick next to him demonstratively, and then said: "Returning to Your Highness, since considering that submarines still have to stay on the surface of the sea most of the time when they are carrying out activities in the open ocean, I have adopted some special methods and methods to appropriately increase the GM value of submarines. His Royal Highness also saw that although the freeboard of the boat was only 0.4 meters, its stability was still worthy of recognition. As for the barbarism of the roll period, it is only inversely proportional to the GM value of one-half of the square, and a little increase in the GM value will not weaken it too much. If the officers and men of our German Navy could not withstand even the slightest shaking, they would no longer have to put on that naval uniform! ”

Qingying nodded slightly, with a hint of approval in her eyes. He pointed to the submarine in the distance that was sailing at full speed, and said, "Mr. Khedira, do you see, what is the speed of this submarine?" ”

Khedira was slightly stunned when he heard this, and was about to take a closer look, when Frick next to him had already spoken: "Back to Your Highness, when Little Khedira designed it, he installed a large gasoline engine with a power of 40 horsepower, which can propel it to sail on the water at a speed of 7.1 knots. And according to my observations, the speed of this submarine has already reached 7 knots. However, it is only the first step of surface navigation, and the rest of the underwater navigation and torpedo attacks have not yet begun to practice, and it is still impossible to judge its overall performance. ”

"Flick, you guy, wait and see, the things I designed will never be a problem!" Hearing this, Khedira glanced at the man with one-sided glasses, then turned his head and said to Qingying, "Your Highness, you will soon see the last test of this submarine. We towed a barge in the open sea, which served as a target for the submarine to carry out torpedo attacks. It will start diving 6 nautical miles from the target ship, then sail to a distance of 1,000 meters with the power of an electric motor, and finally launch a torpedo attack underwater. Since the barge is 10 nautical miles away, I would like to ask His Highness to go out on a yacht and watch the scene up close. ”

When Qing Ying heard this, she looked far ahead, and with the pair of 1.5 titanium alloy eyes of this body, she saw a pitch-black dot at the junction of the sea and the sky. With his approval, the three men stepped down from the stands and boarded the yacht; Half an hour later, the dilapidated barge came into view.

Out of the port, the cold wind overseas was even stronger, and Qingying couldn't help but wrap her coat tightly. The waves on the surface of the sea swayed, constantly crashing against the side of the yacht. Looking at the endless sea, Khedira said, "The submarine has already dived and is heading towards the target ship. I installed a 15-horsepower battery-powered unit on this submarine, which can keep the submarine at 5.2 knots underwater for 50 nautical miles, and it is expected that in another half an hour, the submarine will reach the predetermined torpedo firing position. Since the development of the new 450-mm torpedo with a range of 3,000 meters has not yet been completed, the torpedo tubes equipped on this submarine can only fire the old torpedo with a range of 1,200 meters. ”

Qingying nodded slightly. Historically, the German Navy was only equipped with a new torpedo with a range of 3,000 meters in 1905. After another half an hour of the cool breeze, the waves parted, and a black periscope suddenly rose on the surface of the sea ten meters away from the side of the yacht. Under Qingying's dull gaze, it spun around on the swaying sea, and then focused the camera on the yacht that was close at hand! Seeing this scene, Qingying's hair stood on end, if this group of guys used their ship as that barge and carried out a torpedo attack, it would be a lot of fun!
