The main way to deal with submarines is to detect them in advance.

The submarine must attack from the side to be effective, so as long as the opponent is spotted and turns 90 degrees by himself, then he can make the opponent's submarine go around in a big circle, and when the opponent reoccupies the launch position, then he will turn again.

This premise is to know that the submarine is there, and in later generations, there is advanced sonar equipment, and in this era, it depends on human intuition.

Cridis's instincts saved the ship again, and he turned twice and avoided two torpedoes, which was enough for Mohel to beat his chest, but their good fortune was stopped.

"Dodge." In the position of the tail gun, Clitis did not fire, his eyes were extremely sharp, and he actually saw the trajectory of the torpedo swimming under the water.

The movement of the electric torpedo is very small, but its navigation still relies on the propeller, which always brings some changes when stirring the seawater.

Dodge!

If he hadn't swerved, he would have been hit by the torpedo, and Cridis felt his back soaked, and every hair stood up again as he turned his eyes to the nearby sea.

"Damn, our port side, and the submarine, captain, quick, left full rudder, oh no, right full rudder, oh no, accelerate!"

He didn't know what to do.

If it's a warship, you can fill the rudder on the left and rush in the direction of the submarine, but they're cargo ships, why rush up? How to fight with someone with a bayonet?

If you can't have a full rudder on the left, then a full rudder on the right? This will not work, if the right rudder is full, it will be given a good chance to launch a torpedo by the submarine just now, so, after hesitating twice, he finally said it and accelerated.

This is useless, because just now the cargo ship was in the process of acceleration, and now the acceleration does not change the state of navigation at all, and it is not possible to slow down, there is no brake on the slow freighter, and the deceleration is just the propeller reversing, and at this emergency moment, reversing the propeller will not save them.

"Boom!" An electric torpedo made close contact with its side with ease, and then a massive explosion tore open the watertight compartment below, pouring sea water into it.

The German torpedo can kill a 10,000-ton warship with just one torpedo, and although the merchant ship is also 10,000 tons, the construction standard of the merchant ship is low, and it is not resistant to attack at all.

As the sea came in in a surging wave, everyone knew that the ship was about to sink.

They quickly threw off the lifebuoy and jumped into the water.

The same goes for Critis, who gasped and looked at everything around him as he struggled to catch his swim ring.

Cargo ships were being besieged, and under the blows of German submarines, they had no room to fight back.

This is simply a one-sided massacre, when the escort ships have been killed, the remaining cargo ships have only the fate of being slaughtered.

The U-107 submarine, which was the first to discover the fleet, was naturally the first to be discovered.

"Launch!" Heisler shouted loudly, and the torpedo came out of the water and headed for the ship, which was speeding away, and then the bottom of the ship exploded violently and stopped.

There were constantly crew members jumping from above, and the scene was chaotic, but unfortunately, their luck was very bad.

"Boom!" A few seconds later, the cargo ship suddenly exploded into an even more terrifying explosion, and in the explosion, the entire cargo ship was suddenly blown apart from the middle and turned into pieces.

"Quick, drop the periscope!" Heisler shouted, as soon as his periscope was lowered, debris was already flying over the surface of the sea, and at the same time, the water was shaking violently.

What is this cargo ship transporting? This explosion is too elaborate, isn't it?

With the exploding cargo ship as the center, the sea water radiated outward in a wave-like circle, spreading in circles, and the waves were actually five or six meters high!

Two nearby cargo ships were unfortunately hit by flying debris, and then, with the shaking of the waves, they actually lifted the hull.

This is simply an explosion at the level of an ammunition depot!

In the underwater submarine, the submariners also covered their ears, the sound was terrible.

When the explosion subsided, Heisler raised his periscope again, rolled up his sleeves and continued to work, murderously looking for their next target, and the sea was their prey.

Kamchatka Peninsula.

It was a long strip of peninsula located in the Soviet Far East. It is bordered by the Sea of Okhotsk to the west and the Pacific Ocean and the Bering Sea to the east. It is the second largest peninsula in the Soviet Union.

The earth's crust is unstable, volcanically active, earthquakes are frequent, and there are many hot springs and geysers. There are more than 160 volcanoes.

The climate is cold in winter and cool in summer, there are modern glaciers in the high mountains, and the central and southern parts of the peninsula are forest areas, widely distributed with conifers, birches and aspen trees dominated by larch; The northern part is forested tundra and tundra. Forests cover 40% of the peninsula's area. There are various mineral deposits.

Therefore, it is not suitable for human habitation at all, it has always been sparsely populated, and most of the area is in an undeveloped state.

Now, in the southern part of the peninsula, Petropavlovsk, the largest city and the seat of the capital, with a population of only a few tens of thousands, is dominated by fishing and fish processing in peacetime, and on the outskirts of the city, the naval aviation units of the Far Eastern Military District are newly built.

After receiving the news, they were extremely nervous, and one after another SB-2 bombers, carrying anti-submarine deep bombs, hurriedly left the runway of the airport.

"Our cargo ships are being attacked by German submarines, and we have to rescue them." On the long plane of the bomber, Major Evgeny said, his heart was extremely anxious.

Although in the Far East, they were also concerned about the battles on the Western Front, and the situation was quite unfavorable for the Soviets, who would probably not have been able to hold out without a blood transfusion from the United States.

If geographically, the United States and the Soviet Union are only separated by the Bering Strait, it seems that it is possible to take a boat and ferry from the Bering Strait, but in fact, this is not possible at all.

Because the vast Far East of the Soviet Union was deserted, there were no railways, the weather was cold, the forests were dense, and there were no roads at all. Sea freight is the lowest cost and most efficient mode of transportation.

They are tasked with protecting sea lanes.

The SB-2 bombers flew quickly to the southern coast, but when they arrived, all that was left was a mess on the sea.

The whole fleet, torn by the German wolves, was in tatters, leaving not a single intact cargo ship, and on the sea, a human head floated, as if telling something.

Why didn't you come here earlier, the Germans had already run away. Damn, the Germans' submarines, I'm afraid there are twenty of them.
