"No. 1, No. 2 launch tube, g7u torpedo, fixed depth of 10 meters, maximum speed." Prien shouted loudly, and his voice reached the torpedo compartment in front through the telephone in the boat.

At this time, although the officers and soldiers in the torpedo compartment could not see the target, they knew that it must be a big target.

The larger the displacement of a warship, the deeper the draft. For ordinary warships within 10,000 tons, a fixed depth of 3 meters is enough. Now, a fixed depth of 10 meters is definitely a big guy with a displacement of more than 30,000 tons!

Moreover, special torpedoes are used!

On the U-47, dozens of torpedoes were equipped, but there were only two of this G7u torpedo. Generally speaking, only the most experienced submarine dared to carry this torpedo.

This is a torpedo that has not been historically, where g means a diameter of 533 mm, 7 means a length of 7 meters, and the u afterward represents hydrogen peroxide.

In this era, most torpedoes were electric torpedoes, and their technology had developed and matured, and this hydrogen peroxide torpedo is still a new thing.

This kind of torpedo from Germany also comes from the island country. When Cialek visited the island country, he signed many projects, including the introduction of the technology of the island country's Type 93 oxygen torpedo.

Oxygen torpedo is a thermally powered torpedo, which only replaces air with oxygen to allow the fuel to burn fully. Such torpedoes have a longer range, faster speed and great power.

During World War II, only Japan used it, for no reason, because this thing was unstable.

Due to the relatively backward technical conditions of the island country and processing technology, the safety and reliability of this torpedo are reduced. The enemy warships killed and their own warships killed due to self-destruction are 1.5:1!

Therefore, other countries are discouraged, and the probability of serious accidents is not something that the captain of the submarine is willing to carry.

However, the United States was deeply impressed by the Jiusan torpedo that had suffered a lot, and organized special forces to develop two similar oxidizing agents (hydrogen peroxide) torpedoes: mk16 and mk17.

At least because the development time was approaching the end of the war, neither of these two torpedoes were finally put into service.

Cyric's time travel brought various advantages of foresight. After introducing Japan's oxygen torpedo technology, Germany did not immediately imitate it, but instead made great efforts to transform reliability.

One of the key problems in the unreliability of the torpedo in Japan is that the collision fuse is too sensitive. After the magnetic fuse is used, this problem was solved.

After years of hard work, the current g7u torpedo, codenamed t11, is already mature and can be carried by submarines.

Even if the safety issue is improved with great efforts, hydrogen peroxide is congenital instability after all, and aircraft cannot be carried. Submarines are now only carrying a small number of trials. For example, the current U-47 has only two such things.

After receiving the order, the torpedo soldiers on the bow immediately became busy.

Using a special wrench, the torpedo's mechanical depth setting device was twisted, and the sound of a spring twisting came from inside. Soon, it was set to a ten-meter position.

Only in the late stage of World War II did torpedoes have the means to adjust the depth at any time, and now torpedoes must be adjusted before entering the launcher.

Then, using devices such as hanging chains, several shirtless torpedomen stuffed the torpedo into the launch tube in front.

"Bang." The launch tube was closed, and the torpedo shouted loudly: "The torpedo has been loaded, and the depth is set to eight meters."

"Left rudder 1." Prien continued to shout. If the torpedo is compared to a bullet, then his submarine is a gun. Especially when it is to fire this special torpedo, there is only one way to fly directly, and he must aim.

"Open the launch tube."

The helmsman swung the rudder, and the torpedo soldiers manually opened the launch tube, and then they heard the sound of surging sea water flowing in.

If you want to launch the torpedo, there are many ways, such as pushing it out with compressed air, or injecting water into the launch tube in advance so that the torpedo can swim out by itself.

Now, that's the latter way.

"Target confirmation, War-Welfare, two g7u torpedoes, direct flight, three seconds apart, launch!" Prien shouted loudly.

emission!

The torpedo soldiers pressed the last button, and as the command was conveyed, a terrible sound of water flowing sounded between the launch tubes No. 1 and No. 2.

Hydrogen peroxide and alcohol mixed into the torpedo engine, burning violently, driving the propeller at the tail, turning quickly, and swam quickly from the torpedo launch tube!

Soon, the torpedo accelerated to its maximum speed, a terrible 46 knots!

The average electric torpedo is the limit when it reaches 30 knots, and this new torpedo can easily reach a high speed of 46 knots! And the Japanese Type 93 can even reach 48 knots!

The combustion of hydrogen peroxide and alcohol, the waste was melted into the water, and it was difficult to see any bubbles. Two torpedoes rushed to the huge battleship in front.

At this time, the officers and soldiers of the War-Fat were still trying their best to rescue the warship, closing the cabin at the bottom, and starting the drainage pump to extract moisture. At this time, the hull had already begun to tilt slightly.

Ten meters deep under the water, a 7-meter-long torpedo whistled, and nothing could be seen on the water!

The armored belts of warships are all distributed on it, so the appropriate depth allows the torpedo to avoid single armor attacks. At the same time, the different fuses also cause the torpedo to attack differently.

When there is no magnetic fuse, the target draught is usually about one meter less than the target, and it directly collides and explodes.

After having magnetic fuses, they have to be one meter more than the draft. They explode at the bottom of the ship, and use the water pressure generated by the explosion wave to lift the ship from the middle, so that it will be broken directly!

Of course, this torpedo is deeper and needs to pass through the bottom of the ship, which means one meter more than the draft.

If it is in ordinary circumstances, after the submarine launches a torpedo, it must dive immediately. After all, once the fire is opened, the other party will know its existence and how far it can escape.

But now, Prien did not hide, and he wanted to see the end of War Warfare in the periscope.

The war-weary number, with a standard displacement, a draft of 9.2 meters and a full load of 10.35 meters. Now, looking at the other party, it should be about nine meters of water, and the depth of 10 meters is determined by himself, which is just right.

In almost one minute, the huge torpedo penetrated under the War Warfare, which was exactly the same as Captain Prien's guess. The torpedo was almost one meter deep below the opponent.

"Boom!" The magnetic fuse detonated the torpedo's 400 kilogram charge, and a violent explosion occurred along with the unburned hydrogen peroxide and alcohol.

The explosion pushed the surrounding sea water, forming a huge water pressure, pressing on the bottom of the War Yan. The surging sea water hit the middle of the War Yan. In this terrible impact, only the twisted sounds of steel that make people's teeth softened were heard.
