When a staff officer heard Yu Feng's words, he took a chair and handed it to Ichiro Abe, who was so distraught that he forgot about it, and the soldier on one side took the chair and put it next to Ichiro Abe, and Ichiro Abe sat down in despair.

Yu Feng picked up the communicator and said loudly: "Sonar chief, report the target details immediately." ”

The sonar chief then reported: "Number of targets, five, target distance, three kilometers; Target azimuth, 75 degrees east-north; Target Speed: Eight knots! ”

When Yu Feng heard the report, he thought in his heart, "Eight sections? Didn't Ichiro Abe tell me that their speed was only three knots? It is also said that this is to save fuel! Our guess was correct, and Ichiro Abe wanted our warships to rush in front of their submarine so that they could attack us from behind. ”

Yu Feng then ordered: "Prepare for torpedo launch!" Anti-torpedo systems ready! The reason why Yu Feng ordered the anti-torpedo system to be prepared was because Yu Feng did not know the detection level of the Japanese sonar in the channel, let alone how far the detection sonar of the Japanese army in the channel could hear the sound of his warship.

Although Lin Yuan came up with a way to take out the sonar for research, he found that the sonar had been damaged, and it was almost impossible to repair it, because they didn't have the accessories used in Japanese sonar, and if they put their own accessories on it, it would be to study their own sonar, so the sonar was not repaired well.

Yu Feng did not know the range of the Japanese sonar, so he could only assume that the sonar on the Japanese submarine had discovered his warship, so he had to be prepared to defend against torpedoes.

At this time, a message came from the torpedo room: "Report to the captain, the torpedo is ready for launch, request the sonar room to transmit information on the movement of the target." ”

Yu Feng immediately said: "Sonar chief, transmit the target movement information to the torpedo room!" "Commanded, sonar chief immediately turned on the target tracking mode, sonar is the same as radar, at the beginning of the detection is the search mode, this mode only finds the target, does not track the target, when the sonar chief turns on the target tracking mode, the sonar will be based on the received sound waves for target tracking.

After receiving the order, the sonar chief sent back a message: "The tracking mode has been turned on, and five Japanese submarines have been locked. ”

Yu Feng then said: "Torpedo room, launch torpedoes!" ”

The torpedo room then set the parameters of the torpedo, pressed the button for the torpedo launch, and then reported: "Captain, the torpedo has been successfully launched!" The sonar chief then sent a message: "The sonar has detected the torpedo signal and is entering guidance mode." ”

The torpedo launched by the Lin Yuan warship is a "line-guided and acoustic self-guided" torpedo, and the attack process of this kind of torpedo is divided into two stages, the first stage is the "line-guided" stage, the so-called "line-guided" is the torpedo with a wire dragged on its body, and this wire is connected to the launch carrier, which transmits the target information to the torpedo through the wire to control the navigation of the torpedo.

The second stage is the "acoustic self-guidance" stage, in which the sonar carried by the torpedo actively emits sound waves, detects the target position, tracks the target, and hits the target at the last time.

This guidance method sounds very outdated, in fact, in Lin Yuan's era, the vast majority of models of torpedoes are guided by this method, and there are only a handful of torpedoes that use pure sound self-guidance, that is because the underwater sound transmission environment is extremely complex, and simple acoustic self-guided torpedoes are easy to miss the target, and if the civilian ship is sunk as a target, it will bring great trouble to the military.

The Fire Phoenix and Kirin each fired six torpedoes, and twelve torpedoes were directed at the Japanese submarines, but Ichiro Abe, who was sitting on the side of the command room, was a little relieved in his heart, because he heard the sonar soldier report that five submarines had been found! This means that there are five submarines that have not been discovered, and if those five submarines find Lin Yuan's warship after being attacked, then they still have the possibility of turning defeat into victory.

At this time, in the command room, a simulated image of a torpedo attack submarine had already appeared on the big screen, and five blue light spots appeared on the screen, which were marked as the No. 1 target and the No. 2 target from front to back...... At Target Five, twelve red dots of light in two rows were slowly moving towards them, and since the torpedoes were launched at an interval of twenty seconds, the torpedoes had a sequence in the water.

Yu Feng looked at the big screen, silently expecting the torpedo to hit the target, and then the sonar chief sent a report: "Report to the captain, the first torpedo has pulled the target into the acoustic self-guidance range, do you cut the wire and turn on the sound self-guidance?" ”

The accuracy of acoustic self-guidance is much higher than that of the wire guide, so at the end of the torpedo attack, the operator will cut off the wire and turn on the acoustic self-guidance mode. ”

"Yes, cut the wire, turn on the sound self-guidance!" The sonar chief pressed the "cut off" button while repeating Yu Feng's command, and the first torpedo immediately disconnected the wire, turned on the self-guided seeker, and rushed towards the target submarine, on the sonar screen, the torpedo slowly approached the target, getting closer and closer, and gradually coincided together, just when everyone thought that the torpedo hit the target, the sonar chief sent a report: "Report to the captain, the first torpedo did not hit the target!" ”

Yu Feng was not panicked or surprised, he was very clear in his heart: "There are too many accidents of torpedoes attacking underwater targets, and the probability of hitting the first shot is actually very small, but it doesn't matter, if the first one misses, the later torpedoes may still hit." So he looked intently at the second red dot, but at that moment, the sonar chief sent a message: "Report to the captain, the first torpedo exploded!" ”

Yu Feng said in surprise: "What? Exploded? Didn't it pass from the target? How can it still explode? ”

"We don't know, maybe there are more than five targets!" It is possible that the Japanese submarines were lined up in some kind of formation, and our sonar could not hear all the targets. ”

Yu Feng thought to himself: "The battle has begun, but we haven't even figured out the number of Japanese submarines, how can this work?" So Yu Feng picked up the communicator and said, "Submersible control room?" Immediately control the submersible, move to the side of the target group, and figure out the number and location of the target. ”

The submersible control room immediately began to control the submersible to move towards the Japanese submarine formation, and while moving, the second torpedo approached the No. 1 target, and at the moment of coincidence, the sonar chief sent a message: "Report to the captain, the torpedo hit the Japanese submarine!" We've heard explosions. ”

Yu Feng said happily: "Okay! Then he peeked at Ichiro Abe, and then said, "Cut the sound into the command room and let everyone listen!" ”

The sonar chief then said, "Okay, no problem! After a while, he cut a dull voice into the command room, and the sonar chief said: "This sound is the sound of an explosion, and this explosion happened underwater, so it doesn't sound like the kind of explosion you usually hear." ”

Yu Feng suddenly heard a "bang" sound in the explosion, as if someone was hitting something with a sledgehammer, and couldn't help asking, "What is this sound?" ”
