After Yu Feng finished speaking, he picked up the communicator and said, "Kirin, there is a very good chance that there is an enemy submarine hidden under the oil tanker of the Chief Gali, you must be careful to deal with the possible attack it may launch." ”

Su Lin, the captain of the Kirin, said: "Yes, we understand. After receiving Yu Feng's message, Su Lin thought to himself: "If the submarine in the water wants to attack us, it will inevitably use the method of launching torpedoes, so as long as we defend the torpedoes, we can ensure that our ships are not attacked by the enemy." ”

So Surin ordered: "The anti-torpedo system is ready, and all efforts are made to guard against the torpedoes fired by the opponent!" After Su Lin gave this order, he thought: "We can't just guard against their torpedoes, we still have to find and destroy the submarine, but the submarine is very close to the large oil tanker, and the noise from the movement of the submarine will be blocked by the noise of the oil tanker, so it is difficult for the sonar to find the submarine hidden under the ship, in this case, we have to take some special measures." ”

Surin said: "Immediately adjust the range resolution and azimuth resolution of the radar to the maximum, search the sea surface, and look for the periscope of the submarine!" The torpedo is ready to be fired! ”

At this moment, Surin suddenly received a message from Yu Feng: "Surin, immediately retreat and stop the operation against the Chief of Gali!" ”

Su Lin hurriedly asked, "What is this for?" We have prepared anti-torpedo systems to prevent the adversary from attacking, we have also prepared the radar to look for the periscope of the opponent to the surface, our radar resolution can do this, so we are not afraid of their submarines at all! ”

Yu Feng said: "If there is really a submarine under that oil tanker, it is very likely that they will attack you when they are very close to you, the No. 1 torpedo used by the Japanese army has a very fast speed, it can even reach forty knots, so close distance, such a fast speed, you may not have time to launch anti-torpedo weapons!" And the Japanese torpedoes are very lethal, if a torpedo hits our warship, it will undoubtedly have a devastating blow to our warship! ”

Surin said: "If we retreat, don'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 submarines!" ”

Su Lin said: "Okay, I'll withdraw it!" So Surin ordered the Kirin to turn around and no longer sail towards the Chieftain Gali oil tanker, at this time Yu Feng picked up the communicator and said to the torpedo launch department: "Torpedo launch department, quickly enter the battle position." ”

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

The staff officer said: "The standard draft is sixteen meters. ”

Yu Feng said: "Observation department, report the current draft depth of the Chief Gali!" ”

The observation department immediately replied, "About sixteen meters." ”

Yu Feng thought in his heart: "Since the draft of Chief Gali is sixteen 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 eighteen meters, counting the draft height of the submarine itself, I asked the torpedo department to mark the torpedo depth at twenty meters, which should be able to hit the enemy's submarine." Thinking of these Yu Feng ordered: "Torpedo department, mark the torpedo depth of twenty meters!" ”

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

Yu Feng said: "The minimum depth is thirteen meters!" "Calibrating the minimum diving depth" is a way to prevent the torpedo from accidentally injuring friendly forces, after the minimum diving depth is calibrated, the torpedo will not enter a depth smaller than the minimum diving depth, and the friendly warships are all operating at a depth smaller than the minimum diving depth, so even if the torpedo misses the target, it will not accidentally damage your own warship.

The torpedo firing department then said: "The minimum depth is calibrated!" ”

Yu Feng said: "Start the launch procedure immediately, target, the underside of the Ghary Chieftain oil tanker, launch!" "The torpedo department immediately began the firing procedure, and the high-pressure gas was filled into the launch canister, and under the impetus of the high-pressure gas, the torpedo rushed out of the launch canister and fell into the water, splashing a spill.

The torpedo used by Lin Yuan's troops is an electrically powered torpedo, which is a motor, while the torpedo used by Japan is a thermodynamic torpedo, which is a heat engine, and this torpedo of Lin Yuan's troops uses a silver-zinc battery as an energy source, and the battery drives the electric motor when it moves underwater, and the motor drives the propeller, and there is no exhaust gas spilling out of the torpedo during the whole process, and naturally it will not form a track in the water, so it is difficult to be found by the human eye.

The fire fired three torpedoes, and the sonar operator began to track them, but soon the torpedoes disappeared from the sonar soncer's screen, as the sound of the torpedo motion was obscured by the loud sound produced by the propeller in the stern of the Chief of Gali.

Lin Yuan's torpedoes have a variety of non-contact intelligent fuzes, including sound fuzes, magnetic field fuzes, and so on, but this operation is to hit submarines under oil tankers, so the three torpedoes have been replaced with the most primitive trigger fuzes.

After the three torpedoes were fired, the oil tanker of the Chief Gali did not move, still maintaining its original speed and moving into the distance, Yu Feng estimated the time, and thought in his heart: "It's almost time, the torpedo should be under the ship, I wonder if the road has hit?" If it hits, a violent explosion will definitely set off a column of water. So Yu Feng raised the binoculars and looked into the distance, but he didn't see the water column rising, and thought: "It seems that it didn't hit, no, could it be that the torpedo deviated from the course?" Probably not, our torpedo has a steady-state system with a laser gyroscope as the core, and the torpedo will not deviate if the course is set! ”

"Could it be that there are no submarines down there?" Yu Feng couldn't help but smile dumbly when he thought of this, and thought: "It seems that there may really be no submarine below, but we are thinking too much." In order to be able to observe whether the three torpedoes hit the target, Yu Feng ordered the Kirin to sail in front of the Sheikh Gali oil tanker, and use sonar in front of it to observe the trajectory of the three torpedoes, the sound of the bow is much quieter than the stern, the sonar on the Kirin can detect the torpedo, if you see the torpedo passing under the Sheikh Gali, it means that the torpedo did not hit the submarine below, or rather: there is no submarine under the oil tanker.

Ten minutes later, the Kirin overtook the Ghaerate with its speed of 25 knots, and Yu Feng immediately ordered three more torpedoes to be fired, and three minutes later, the Kirin reported: "The first torpedo has been found coming out from under the tanker!" Five minutes later, the Kirin sent another report: "The second torpedo came out from under the tanker. ”

Yu Feng heard these reports and thought to himself: "It seems that the third torpedo will also pass under the oil tanker, it seems that I really think too much, there is no submarine under the oil tanker at all, alas, it cost six torpedoes in vain." At this moment, a large column of water suddenly rose under the water, splashing down from both sides of the Chief Gali, and then saw the hull of the Chief Gali swaying slightly, Yu Feng thought to himself: "This torpedo, it won't hit the Chief Gali, right?" ”
