In the 1940s, because of the double limitations of sonar technology and depth charge technology.

At that time, no one knew exactly where the submarine was when the depth charges exploded. Moreover, depth charges are dropped in dozens and hundreds, and no one knows how powerful a single shot can be after being thrown into the deep sea. Some of them are just theoretical reference data.

For example, a "hedgehog" bullet has a charge of 35 pounds. Use trigger fuzes instead of depth fixing fuzes. Bomb only with a direct hit. This kind of submarine will hang up with 2-3 rounds in a round, but only if the depth charge happens to collide with the submarine intimately. Ordinary depth charge 300 pounds. You can brainstorm this kind of ......

Anyway, if the submarine is hit by a close distance, it will definitely become scum. There is also the fact that deep bombs are generally graphic throwing, throwing a bunch of them.

This is why Li Gengxin will feel like hail outside in the submarine.

Of course, these "hailstones" exploded one after another after reaching depth.

"Stopped? Has our plan worked? Although Li Gengxin was still ringing in his ears at this time, there was no longer a feeling of being swayed madly in the submarine at this time. There was no more endless tremors, just some pipe walls were still squirting water.

"Holy! Great......" Li Gengxin cheered alone, and suddenly saw that the people around him were looking at him with sharp eyes.

Li Gengxin suddenly froze, and Dai Mengrao whispered in Li Gengxin's ear at this time: "If you are not afraid that they will hear it with sonar, you will shout!" ”

At this time, there was a quiet silence in the submarine of the Shooting Fish. The engine of the accumulator has long been turned off. And Li Gengxin's voice and the sound of water spraying in the submarine are so abrupt.

"Uh...... Oh, oh, oh......" Li Gengxin's face turned white instantly. Hurriedly nodded to show that it understood!

At this time, Dai Mengrao took two steps towards Li Gengxin, leaned next to him, poked his head out and muttered, "Wait until you go back." I'll be your wife, okay? I ......"

"Huh?" Li Gengxin subconsciously froze.

"What? Don't want to? Dai Mengrao wrinkled his little nose, and there was such a cute smile on his face.

"Uh......" Li Gengxin didn't understand what was going on from beginning to end. But looking at Dai Mengrao's eyes, there was a lot of affection. He just nodded perfunctorily first, and showed a few snow-white teeth with a bitter smile.

"Major! What do we do now? "The first mate standing next to the nautical chart. He asked Li Gengxin speechlessly.

"Wait! Wait a minute! The Shinano was about to sink. They will lean over to the Shinano in a moment to save people. When the time comes, we are quietly retreating! After Li Gengxin finished speaking, everyone felt that it made sense.

But only Dai Mengrao, who was standing aside, frowned slightly. It always seems like a wise choice to play dead here. Then Dai Mengrao gently said to Li Gengxin: "I think it's better for us to leave now!" I was always unsure, thinking that something might happen. ”

"Now? Now, if we move, we will be discovered by the destroyers that are still cruising above! Li Gengxin frowned, not taking Dai Mengrao's question too seriously.

"At this time...... What are we going to do at this time? Dai Mengrao asked Li Gengxin.

Li Gengxin shrugged his shoulders helplessly, and complained in his heart: "I don't know what to do yet." You come and ask me? ”

Time passed quickly, but everyone in the submarine felt like they were living like years. Li Gengxin held the watch in his hand and read the changes in the second hand above. I finally waited for fifteen minutes, and was about to give the order. Suddenly, I heard the sonar soldier behind me shouting with a crying voice: "Depth charge!" Depth Charge ......"

Actually, depth charges after the explosion. The sonar of the Japanese takes 15 minutes to be undisturbed. The recovery on the Shooting Fish was slightly faster than that of the Japanese, but the gap was not large.

Because Lee ordered the clothes to be sprayed out with torpedo tubes, the action and the final explosion of the depth charge was the time of the front and rear feet. Everyone subconsciously thought that Li Gengxin's "Ecstasy Array" had mistakenly let the Japanese fall for it.

However, everyone did not expect that the sonar that was actually supposed to be Japanese could no longer find the location of the Shooting Fish. Only then did the continued dropping of depth charges stop.

Subsequently, the clothes that Li Gengxin ordered to spray out and some fuel from the submarine came to the surface of the sea, which indeed made the Japanese mistakenly believe that their depth charges had sunk the Shooting Fish.

However, because it has not yet reached the rescue time set by Toshio Abe, and the commander of the two destroyers wants to avenge the "classmates" who died. The commanders of the two destroyers discussed it, and only after fifteen minutes did they make up a few more slashes.

The last batch of depth charges was "mercilessly" dropped by them. After the last depth charge is ejected into the air. The destroyer began to turn the rudder on the surface of the sea.

With a muffled pop, the depth charge plunged headlong into the depths of the sea.

The two destroyers hurried towards the Shinano, which was already leaning more and more.

After all, during the period when they could not attack after the sonar failed, the two destroyer commanders were more anxious than Li Gengxin and others in the sea, and they also wanted to rush to rescue the officers and soldiers on the Shinano and a large number of skilled workers.

Destroyers chasing submarines in the deep sea from head to tail in games and movies are non-existent in reality and obviously unscientific.

The dropping of depth charges is actually the same as the straddle that occurs when a battleship hits a counter-bombardment. When the opposing shell completes the straddle and the shell falls behind it. In fact, people have already mastered the shooting point. The rest of the matter is like using a pencil to poke in this circle quickly. As long as you poke enough, there will always be black dots that will land on the spot you want to touch.

Depth charges are based on the same principle as straddle fire. It is also to poke the approximate position in the sea. Enough of them. There will always be a time when you can tear open the thin shell of the submarine.

But sonar is sad.

In fact, after the first explosion, the sonar loses its target. It will take more than ten minutes before you can start positioning again. From positioning to finding to throwing, it was at least half an hour.

When the time came, the sonar once again spotted the Shooting Fish, which was almost sitting in the depths of the ocean.

Under the divine mending sword, there was a bitter shout from the sonar soldiers.

"Bang...... Boom...... Bang bang ......"

A series of explosions occurred again in the depths of the ocean. At this time, Li Gengxin, who was in the submarine of the Shooting Fish, gritted his teeth. Get ready for a new baptism of the wind! (To be continued.) )
