In this era, the only way for submarines to attack is to use periscopes to aim. Under the captain's command, the torpedo comes out of the water and relies on the captain's experience to attack the target.

Without a periscope to aim, there would be no way to attack. The Soviet Union did not have the advanced sound-guided torpedo from Germany, but only direct flight torpedoes, just like using a sniper rifle to attack the enemy.

Now, the despicable means adopted by the Germans have only one purpose, which is to prevent the submarine from using periscopes to aim!

In fact, the Germans did do it. In this case, it is possible that anyone who uses a periscope will not be permanently blind and will not be able to see it briefly. If he wants to issue an attack order, he must observe the target continuously and determine the shooting of various elements. Now, this opportunity is gone.

He can't attack the opponent, so what will the opponent continue to do?

No need to think about it, of course, I used a deep bomb to blow myself up!

"Dive to fifty meters!" Bristov shouted loudly. After regaining his vision, he shook the turntable with his hand and lowered the periscope. Now, he can no longer use the periscope, but the Germans will use deep bombs to blow him up.

When using the deep bomb, there are many restrictions. You must estimate the depth of the target before you can blow it up. Now it has a periscope depth, which is less than twenty meters. Then he can dive to fifty meters and dodge perfectly.

At the same time, after the other party has passed, he will quickly float up and attack him from behind.

The battle is not over yet!

The m-class submarines are all small and exquisite, with a displacement of hundreds of tons, which makes their movements very fast and effective. As the rudder surface moves, the submarine quickly drills into the water.

At the same time, the entire submarine began to remain silent. The sailors even stood on tiptoe even when walking, while the sonar was the focus of the entire boat. He wore headphones and listened to the movements on the water.

At a depth of fifty meters, the submarine leveled and the motor at the tail stopped. The entire submarine seemed to be a fish that stopped swimming in the sea water, floating with the sea water.

Time passed by little by little, and the fleet on the sea was approaching.

"Bang, bang!"

In sonar, the sound of the anti-submarine deep bomb falling into the water was so clear that the sonar shouted in a low voice: "The other party has begun to drop deep-water bombs about one nautical mile."

After saying that, he was counting in his heart, one, two, three... When he counted to twenty, he heard the sound of a bomb exploding in the sea.

"The depth of the deep bomb explosion is about fifty meters." He calculated it carefully and got this terrible number.

"Go ahead three, dive, and dive to a depth of one hundred meters immediately!" Bristoff shouted loudly.

Fifty meters, the other party is simply a devil! Bristoff is already a little incredible now. How could the other party's commander know his current location?

The battle between a submarine and a surface ship is often more like two gamblers, guessing each other what cards they have in their hands.

Since the other party fires a flash bomb, it is to prevent one from attacking. Then one side should be still in the depth of the periscope. The depth of twenty meters is the most suitable. It is enough to dive to fifty meters by yourself.

Who knew that the opponent actually set the anti-submarine deep bomb to a depth of 50 meters. The opponent threw the deep bomb like a net, which would easily blow it up.

If you want to avoid it, you can only continue diving!

Their submarine of hundreds of tons is almost the limit of its depth of one hundred meters.

After receiving his order, the mechanics quickly adjusted the power to the forward three position, and the propeller at the tail began to rotate quickly. At the same time, in the submarine's cabin, all the idle people ran quickly towards the cabin in front.

At this time, don't worry about making a sound.

Unlike on TV, when the deep bomb is released, the deep bomb stirs the sea water and makes various sounds, which has long covered the noise of the submarine and then reflected through the seabed. As long as you start using the deep bomb, the sonar will not be able to work within an hour.

At the same time, if the submarine is not moving underwater, it will not be able to achieve the goal of diving. It must first move and continue downward like a plane diving.

Only when it moves can the rudder surface have force, and in order to increase the submarine's diving speed, additional manpower is required.

When all the crew members run to the front cabin and increase the weight of the front cabin, the front will sink and the tail will rise up. At the same time, as the tail propeller rotates, pushing the sea water, the submarine begins to move under the water, and it sails downwards like a thrust.

The floor of the submarine had already felt obviously tilted. After using the battery, the lights inside the submarine became extremely dim. Everyone grabbed the handrail beside them, waiting for the unknown fate.

When the depth meter showed up to ninety meters, Bristov ordered the submarine to be leveled.

The people in the front cabin began to run to the rear cabin, preparing to balance the hull, and at this moment, the huge explosion of the anti-submarine deep bomb came from far to near.

"Boom, boom!"

The explosions came one after another, and it made people feel soft and there was a cavity inside the submarine. The cavity effect would amplify this sound, which sounded even more terrifying.

There is no way to smoke in the submarines, and the sailors have no way to relieve this pressure. Only those with the strongest will can survive on the submarines. Therefore, even the Soviet Union, which was the most scarce, treated the submarine soldiers with excellent treatment, and all kinds of supplies will be given priority to the submarines.

Now, the sailors are holding the canned food they have just been sent, pick it open with a knife, and eat it in big mouthfuls. The canned beef from the United States tastes very good.

The explosion gradually became louder, indicating that the other party was approaching.

Bristoff leaned against the wall of the command tower. The wound on his head had just been bandaged and was still bleeding out. In the wet submarine, the wound was not easy to heal and even festered, but he didn't care.

He was waiting, as a submarine commander, he had to have enough patience.

"Boom!" At this moment, a unique voice came to the submarine.

It is not an explosion of an anti-submarine deep bomb, nor is it a sound reflected from the seabed. This sound looks very low, like a huge sea water, which is suppressing something.

Bristov's face suddenly became ugly. He guessed it all at once. No. M-172, who followed him, might be at a depth of fifty meters, and it seemed that it was bombed by an anti-submarine deep bomb!
