Open an aircraft carrier to fight against Japan

Hoshino Yasuka and Koyama Shiji were on the INO.17 submarine, which is also the latest submarine of the Japanese army. The submarine is equipped with a high-power communication system, which allows the submarine to communicate when it is on the water. At [-] o'clock in the morning on March [-], Hoshino An He picked up the communicator and said: "Attention all submarines, it is now three o'clock in the morning on March [-]th, and there are still three hours before sunrise. The snorkel sailing state, enter the submerged state, and head to the predetermined sea area."

Anhe Hoshino knew that his submarine was no match for Lin Yuan's surface ships in terms of speed or weaponry. Their only chance of winning was concealment, so they had to charge their batteries in the dark and then enter the submerged state during the day. Not to be spotted by the surface ships of Lin Yuan's troops.

At [-] o'clock in the morning on March [-]th, the sky was still in the darkness before dawn, and the submarines reported separately: "I-[-] is ready, I-[-] is ready..."

Hoshino Yasuka heard that all the submarines were ready, so he ordered: "All the submarines dive and head to the predetermined sea area." Down communication will also become extremely difficult, so it will be difficult to continue commanding after the submarine enters the water, and each submarine will fall into a situation of fighting alone.

However, Yasuka Hoshino has already formulated an action plan for the submarine team, and all ships should follow the action plan. So Yasuka Hoshino began to concentrate on commanding the No. 17 submarine. He picked up the microphone of the communication system in the boat and said loudly : "Fill the main ballast tank with water, deflect the elevator, and dive to a depth of 80 meters."

The main ballast water tank is used to control the lifting of the submarine. When the submarine wants to dive, the valve is opened to let sea water pour into the water tank. The gravity of the submarine itself increases, so it will dive. When the submarine wants to float At that time, air is injected into the ballast water tank to press the water out, and the gravity of the submarine itself is reduced, so it will float up.

If the submarine only depends on the water in the water tank to change the gravity to complete the flotation and dive, the hull will be difficult to stabilize, so elevators are needed to stabilize the hull. The elevators are usually arranged near the bow or stern of the boat. Japanese submarines Elevators were installed on the bow and stern of the boat, and the operator began to adjust the angle of the rudder when he heard Hoshino Yasuka's order, slowly sinking the submarine.

Hoshino Yasuka saw that the pointer on the depth gauge stopped at "eighty", turned his head and said to Koyama Shiji, "Little tiger, can we find the liquid seabed?"

Xiaoshan Shiji said: "That's right, you can search now." After speaking, he called the navigator over, and the navigator put the chart in front of Xiaoshan Shiji, drew a point on the map with the tip of a pencil, and said, "Please Look, this is the position of our Yi NO.17."

Xiaoshan Shiji said: "About ten meters further down, we should reach the liquid seabed, we should try."

Hoshino Yasuka then ordered: "Adjust the main ballast tank and descend another ten meters!" The operator in the command room immediately turned the handle and began to adjust the ballast tank and elevator. The submarine continued to dive downward. Xiaoshan Shiji kept staring at the density gauge on one side, when the density gauge turned upward at a large angle at a depth of 90 meters, Xiaoshan Shiji's eyes lit up suddenly, and he said, "Here we are! We've reached the liquid sea floor!"

Hoshino Yasuka then ordered: "Reduce the engine power to 5.00%, and wait for the arrival of the Lin Yuan warship!" The Yi NO.17 submarine then hid in the liquid seabed at a depth of 90 meters, waiting for the Lin Yuan warship, according to the original plan of the Japanese army , after the submarine team arrived at the liquid seabed, the Yi-[-] submarine would head north and enter the sailing area of ​​Lin Yuan's troop transport ship.

The captain of the I-[-] boat is named Ichiro Abe, and he is also a fanatical supporter of the Japanese Emperor. In the submarine force, his fanaticism is second only to Yasuka Hoshino, otherwise he would not have taken on such a dangerous mission. At this moment He was standing in the command room, his eyes fixed on the sonar soldiers on one side.

During the battle, submarines operate underwater, so the inside of the submarine relies entirely on sonar to perceive external information. The sonar soldiers are the only eyes of the entire submarine. At [-] o'clock in the morning on March [-], the sonar soldiers reported to Ichiro Abe: "In An acoustic signal was detected northeast of our ship."

Abe Ichiro immediately asked: "Which ship sent that signal?"

The sonar soldier said: "It should be a medium-sized transport ship."

On the early submarines, judging the type of target from the sound depends entirely on the operator's experience and feeling, so the captain will unconditionally believe the sonar soldier's judgment, so Abe Ichiro said: "Adjust the rudder and turn to the northeast."

The operator immediately adjusted the rudder and aligned the bow of the boat in the northeast direction,

As a result, the sound received by the sonar became louder, and the sonar soldier immediately said: "Report to the captain, the target is a medium-sized transport ship with a displacement of 27 tons, the bearing is 200 degrees, and it is about [-] meters away from our boat. , heading from east to west."

Ichiro Abe was excited, and thought: "Since there is a transport ship, let's sink it first!" Then Ichiro Abe ordered: "Climb to the height of the periscope, inflate the torpedo tube in the bow torpedo compartment, and be ready for launch at all times. "In a submarine, although the sonar can hear the target's voice and identify the target's location according to the target's voice, it cannot hear the target's ship name and nationality from the sound. Therefore, before the attack is launched, the periscope must be raised. Visually observe the target and identify its attributes.

After ordering the various departments on the submarine, they started to act. The first officer turned on the air pump of the ballast water tank. The air pump pushed the air into the ballast water tank and drained the water inside. Push it up, and the submarine slowly rises. The periscope height of the Japanese submarine is ten meters, so the submarine slowly rises to a depth of ten meters.

As soon as Ichiro Abe pressed the up switch of the periscope, the periscope rose straight to reveal the sea surface. During this process, Ichiro Abe kept his eyes on the eyepiece of the periscope, waiting excitedly for the scene on the sea to appear in front of him. I was also looking forward to it in my heart: "The best thing to appear in front of me is a warship!"

Soon the scene on the sea appeared in the periscope. On the blue sea, a large ship was driving. The large ship had a wide hull and was full of square containers. It was obviously a container ship. On the highest point of the ship, a five-star red flag symbolizing the People's Republic of China is fluttering in the sea breeze.

And behind this container ship, there are several container ships of similar size. Abe Ichiro secretly rejoiced: "My luck is good, I even ran into a transport fleet!" Abe Ichiro turned the periscope while thinking , when turning fifteen degrees, the sight in front of him surprised him.
