Although he had been on the warship for more than a month, all the officers and soldiers of the Kunming ship were very tired, but they were all soldiers after all. Therefore, after receiving the order from the Military Commission, there was no objection. He asked the Huaihua ship to return to the port first, and he joined the Sanya ship, Qingzhou and Yizhou to be responsible for monitoring the trial sailing of the submarine.

The captain of the trial submarine was Hu Wei. It turned out that he was the deputy leader of the sonar team of the radar department of the Kunming ship. In fact, there were no professional submarine soldiers in the crossing army, but the sonar of the warship was used to deal with submarines. Therefore, the soldiers of the sonar team had a very profound study of submarines, and in the old time and space, they had visited submarines and were very familiar with the performance characteristics and operation methods of submarines. The Kunming ship is the most anti-submarine warship in the Chinese naval sequence. The hull sonar and anti-submarine electronic equipment are also the best, and the sonar team equipped is naturally the best. Among them, they are suitable for selecting the captain of the first submarine built by the East China government, at least they know much more about submarines than others.

However, Li Lina, the leader of the sonar group of the Kunming ship, is a woman and is suitable for working on a submarine. Deputy leader Hu Wei naturally became the best candidate. The other three officers on the submarine are also soldiers on the Kunming ship, namely the team leader Chen Yuantao, the steering commander Huang Dajun, and the power team leader Yi Xuan. These four people formed the officer group of the submarine.

This time it is just a test* launch. As long as the * can be launched from the submarine, it is enough. Although the performance of * will be tested, the hit rate is not within the range of the test. Therefore, the target ship is not arranged, but launches * on a cliff facing the shore. As long as * can hit the cliff and explode, it is considered qualified.

* is one of the important weapons in modern naval warfare. Although the performance of this era is still very behind, it is already a naval warfare weapon that all countries attach great importance to. Because of the emergence of *, small ships have the ability to sink battleships. Therefore, in the 1880s, France developed a set of green water naval strategy theory based on *, namely: * is the magic weapon to defeat the enemy at sea, and the one that determines the victory or defeat of the sea will no longer be huge battleships but * attack ships. Therefore, France canceled all battleship construction plans in 1884 and specially built * boats. Although it was later proved that France's Green Water naval strategic theory was completely failed, the role of * was something that no country dared to underestimate.

Of course, when the East China government was first established, it did not have the ability to use it. The * used were purchased from Germany. However, the East China government never gave up the ability to open the * independently. Therefore, based on the * purchased from Germany, it entered the retrograde development. Now it has finally achieved results. The ship-based * was established in 1904 and was officially named "Piracle" type *, and it has begun to be equipped with the People's Army Navy. After the research and development of submarines was on track, the development of the submarine-launched model was also carried out simultaneously, and now it is tested at the same time as the submarine.

The Barracuda type* is a heavy-duty* with a diameter of 530 mm, a length of 5.4 meters, a total weight of 1.32 tons, a warhead charge of 165 kilograms, a trigger lead, a speed of 32 knots, and a maximum range of 5,000 meters.

The mission of the Kunming ship is not only to monitor the submarine's actions underwater, but also to monitor the trajectory of * in the sea to determine the performance of the submarine-launched * and find the direction for further improvement.

A group of warships came to the test waters. The submarine captain Hu Wei ordered the submarine to sink. Although the submarine cannot use radio calls in the sea, it can emit floating antennas to receive radio signals, so it can also contact other warships under the sea.

After Hu Wei gave the order, the submarine was also busy. Because of the sinking of the submarine, on the one hand, the gate of the water pressure tank must be opened and sea water should be injected. In addition, the head of the boat must be injected first to ensure that the head of the boat tilts downward; on the other hand, the horizontal rudder must be adjusted to cooperate with the water pressure tank to inject water.

"Reported to the captain, injecting 80 tons of water, diving depth of 15 meters, inclination of 12 degrees, and speed of 5 knots."

Hu Wei grabbed the handrail with one hand and said, "Stop filling water and restore balance."

Although the maximum submarine depth of a submarine is 100 meters, in actual combat in this era, submarines basically will not dive below 50 meters, because submarines in this era still advance on the seabed by eye sight. When they reach the seabed below 50 meters, their visibility will not exceed 100 meters, which will basically lose their value. Moreover, at this time, the * cannot be launched at the seabed below 30 meters. Therefore, unless you want to hide your whereabouts, the general activity area of ​​submarines is within 50 meters below the sea surface.

After the submarine recovered its balance, Hu Wei ordered the release of a floating antenna to contact the surface ship, and at the same time raised the periscope to observe the direction of the target cliff.

The periscope rose out of the water, Hu Wei put it on the observation hole, looked for a while, and said, "Turn the left rudder by 11 degrees, keeping the speed unchanged."

At this time, the communications soldier reported to Hu Wei that he had resumed contact with the Kunming ship. Hu Wei said: "Tell them that we are going to launch *." Then he ordered: "Water injected from the No. 1* launch tube."

In fact, the principle of underwater emission * is not complicated. It is to inject compressed air into the tail of the emission tube, use the squeezing of the air to push the * out of the emission tube, and then rely on the *'s own power to push the * forward. Therefore, before launching the *, you must first inject water into the emission tube, so that the function of compressed air can be better played.

However, after the * launch, the * launch tube should be closed immediately, and the air is absorbed by the air recovery compartment located near the * launch tube port, which prevents the air from entering the sea water, generating a large number of bubbles and exposing the whereabouts of the submarine.

At this time, the distance of the submarine is about 630 meters from the cliff, which is basically the effective range of this era. It takes about 40-45 seconds to run this distance. During this period, the distance that the submarine can move is about 150 meters, and it is basically impossible to escape on the spot. It can only dive to the maximum dive depth to hide its whereabouts.

"The water injection of the No. 1* launch tube has been completed."

"emission."

With Hu Wei's order, the submarine trembled suddenly. Looking at the lookout window at the bow, you can clearly see a water line shot out from the bottom of the submarine and extending forward.

The Kunming ship on the water surface has already opened the hull sonar of the ship's bow and closely monitored the situation under the sea. In the command room of the Kunming ship, the three-dimensional map of the seabed is displayed on the main display screen, which can clearly see the location of the submarine and the movement trajectory of the *. Of course, the three-dimensional map of the seabed has been prepared long ago. After the establishment of the East China government, it conducted a comprehensive scan of the seabed along the coast of Shandong and generated a three-dimensional map of the seabed as the basis for warships and ships to sail. Now it can save a lot of resources.

*After launching, Hu Wei's eyes kept pressing on the lookout hole, staring at the cliff in the distance, and was reading seconds in his heart, calculating the time. When Hu Wei counted 43 seconds, a column of water suddenly surged up on the edge of the cliff, and dazzling fire and rolling smoke emerged from the sea. A large number of rocks fell off and fell into the sea.

Hu Wei said: "Everyone hurry up and fall carefully." Before he finished speaking, the submarine shook violently. Although Hu Wei had already issued a warning, three soldiers still couldn't stand firmly and fell to the ground. As the submarine shaking, they rolled around on the ground. Although Hu Wei grabbed the handrail tightly and did not fall to the ground, his head hit the periscope. He didn't care about the pain and shouted at the top of his throat: "Stick the rudder, stabilize the rudder."

This is because the shock wave generated after the explosion has an impact on the submarine. Although the submarine is more than 600 meters away from the center point of the explosion, the amount of charge is too much, almost three times that of a 305mm shell, so the impact force generated is naturally greater; the second is that the explosion in the water, and the impact force generated in the water is much greater than that in the air; the third is that the submarine is too small and only more than 600 tons underwater, so the impact force is naturally weaker, and the few warships that are similar to the submarine are much better. Although they also feel a shaking, they are not much different from the big waves.

After about 10 minutes, the submarine stabilized. While touching the position of the hit on his head, Hu Wei said: "Each department reports the situation."

Although the submarine was hit hard, it was only shaking for a while, and there was no loss. Even the floating antenna released from the sea was basically normal and communication was resumed. Of course, several soldiers were injured in the bump just now.

Hu Wei nodded and said, "The second* test shot."

The second * was launched with the No. 2* launch tube. This time, Hu Wei also learned to be smart. Before the * was launched, he took back the floating antenna. After the * was launched, the submarine immediately sank to 70 meters. Sure enough, the impact was significantly smaller this time. The submarine quickly stabilized its balance. After the shock wave subsided, it floated up to the launch position again. The floating antenna was re-released, contacted the surface warship, and understood the results of the launch, and naturally it was successful again.

The third test was the 1 and 2* launch tubes were launched at the same time, and the submarine was still the same. However, only one of the two* exploded and the other was stranded in the shallow reef. The Qingzhou ship sent a small boat to pick up the unexploded * and take it back for testing. Although this method was very risky, it had to be done. Only by bringing the unexploded * back for testing can we find out the problems and improve it.

The fourth test launch was to test the No. 3* launch tube, which is the* launch tube located at the rear of the submarine. After this launch, the submarine did not sink, but immediately drove at full speed and ran backwards. When the explosion occurred, it had already set off more than 150 meters. When the shock wave arrived, it continued to drive with the impact of the shock wave, and it was not affected too much.
