Open an aircraft carrier to fight against Japan

After Yu Feng finished speaking, he picked up the communicator and said, "Kirin ship, there may be an enemy submarine hidden under the Chief Galli oil tanker. You must be careful to deal with possible attacks from it."

Su Lin, the captain of the Qilin Ship, said: "Yes, we understand." After receiving the news from Yu Feng, Su Lin thought to himself: "Submarines in the water must launch torpedoes if they want to attack us, so we only need to defend the torpedoes well." It can guarantee that our ships will not be attacked by the enemy."

So Su Lin ordered: "Prepare the anti-torpedo system, fully defend against the torpedoes launched by the opponent!" After giving this order, Su Lin thought: "We can't just defend against their torpedoes, we have to find and destroy that submarine, But the submarine is very close to the large oil tanker, and the noise made by the submarine's movement will be blocked by the noise of the oil tanker, so it is difficult for the sonar to detect the submarine hidden under the ship. In this case, we have to take some special measures."

Su Lin said: "Immediately adjust the distance resolution and azimuth resolution of the radar to the highest, search the sea surface, and look for the submarine's periscope! The torpedo is ready to launch!"

At this moment, Su Lin suddenly received a message from Yu Feng: "Su Lin, retreat immediately and stop the action on the Chief Gali!"

Su Lin hurriedly asked: "Why is this? We have prepared an anti-torpedo system to prevent the opponent from attacking, and we have also prepared a radar to find the opponent's periscope out of the water. Our radar resolution can do this Yes, so we are not afraid of their submarines at all!"

Yu Feng said: "If there are really submarines under that oil tanker, they are likely to attack you when they are very close to you. The No. [-] torpedo used by the Japanese army is very fast, and can even reach [-] knots. Then With such a short distance and such a fast speed, you may not have time to launch anti-torpedo weapons! The torpedoes of the Japanese army are very lethal, if a torpedo hits our warship, it will undoubtedly have a devastating blow to our warship!"

Su Lin said: "If we withdraw, won't we let the enemy go?"

Yu Feng said: "Don't worry, definitely not, I have already thought of a way to deal with the Japanese submarine!"

Su Lin said: "Okay, I'll withdraw!" So Su Lin ordered the Kirin ship to turn around at an angle and stop heading towards the oil tanker Galli. At this time, Yu Feng picked up the communicator and said to the torpedo launch department: "Torpedo Launching Department, quickly enter the battle position."

After Yu Feng finished speaking, he said to the staff: "What is the draft of the Chief Galli?"

The staff officer said: "The standard draft is 16 meters."

Yu Feng said: "Observation department, report the current draft of the Chief Galli!"

The observation department immediately replied: "About 16 meters."

Yu Feng thought in his heart: "Since Chief Gary's draft is 16 meters, then the submarine below should have a margin of about two meters from the bottom of the ship, so its diving depth should be about 18 meters, including the draft of the submarine itself. Height, I asked the torpedo department to calibrate the torpedo depth at 20 meters and it should be able to hit the enemy's submarine." Thinking of these Yu Feng orders: "Torpedo department, calibrate the torpedo depth to 20 meters!"

The torpedo launch department sent back a message: "The torpedo depth calibration is complete."

Yu Feng said: "The calibrated minimum dive depth is 13 meters!" "Calibrate the minimum dive depth" is a way to prevent torpedoes from accidentally injuring friendly troops. The friendly warships all operate at a depth lower than the minimum diving depth, so even if the torpedo misses the target, it will not accidentally damage the friendly warship.

The torpedo launch department immediately said: "The minimum diving depth has been calibrated!"

Yu Feng said: "Start the launch procedure immediately, the target is below the Chief Galli oil tanker, launch!" The torpedo department immediately started the launch procedure, the high-pressure gas was filled into the launch tube, and under the push of the high-pressure gas, the torpedo rushed out and launched. The barrel fell into the water, splashing a wave.

The torpedoes used by Lin Yuan's troops are electric torpedoes with motors inside, while the torpedoes used by Japan are thermal power torpedoes with heat engines inside. The torpedoes used by Lin Yuan's troops use silver-zinc batteries as energy sources. When moving underwater, the batteries The motor is driven, and the motor drives the propeller. During the whole process, no exhaust gas escapes from the torpedo, and naturally it will not form a track in the water, so it is difficult to be detected by the human eye.

The Fire Phoenix fired three torpedoes directly, and the sonar operator began to track the three torpedoes, but soon the torpedoes disappeared from the screen of the sonar detector, because the sound signal of the torpedo movement was generated by the propeller at the stern of Chief Gary The loud voice of the

The torpedoes of Lin Yuan's troops have a variety of non-contact intelligent fuzes, including sound fuzes, magnetic field fuzes, etc., but this time the battle is going to hit the submarine under the oil tanker, so the three torpedoes have replaced the most primitive trigger fuzes.

After the three torpedoes were fired, the oil tanker Chief Gary remained motionless and was still sailing at the original speed. Yu Feng estimated the time and thought in his heart: "It's about time, the torpedoes should be under the ship, don't you?" Do you know if you hit it? If you hit it, the violent explosion will definitely set off a water column." So Yu Feng raised his binoculars and looked into the distance, but he didn't see the water column rising up, thinking: "It seems that there is no water column. No, could it be that the torpedo has deviated from its course? Probably not, our torpedo has a laser gyroscope as the core of the steady-state system, and the torpedo will not deviate after setting its course!"

"Could it be that there are no submarines below?" Yu Feng couldn't help laughing when he thought of this, and thought: "It seems that there may be no submarines below. We are thinking too much." But Yu Feng didn't dare to be careless, he decided to launch again Three torpedoes, in order to be able to observe whether the three torpedoes hit the target, Yu Feng ordered the Qilin ship to sail to the front of the Galley oil tanker, and use sonar to observe the track of the three torpedoes in front of it. The sound of the stern is much smaller than that of the stern. The sonar on the Qilin ship can detect the torpedo. If you see the torpedo passing under the Galli Chief, it means that the torpedo did not hit the submarine below, or: the tanker below No submarines.

Ten minutes later, the Qilin ship surpassed the oil tanker Chief Galli with its speed of 10 knots. Yu Feng immediately ordered to launch three more torpedoes. Out!" Five minutes later, the Qilin ship sent another report: "The second torpedo came out from under the oil tanker."

Hearing these reports, Yu Feng thought to himself: "It seems that the third torpedo will also pass under the oil tanker. It seems that I am really overthinking. There are no submarines under the oil tanker. Alas, six torpedoes were wasted for nothing. "At this moment, a large jet of water suddenly rose up under the water and splashed down from both sides of the Galli Chief, and then saw the hull of the Galli Chief shake slightly, Yu Feng thought in his heart: "This one The torpedo didn't hit the Chief Gary, did it?"
