"No. 1, No. 2 launch tube, G7U torpedo, fixed depth 10 meters, maximum speed." Prien shouted loudly, and his voice was transmitted to the torpedo compartment in front through the intercom in the boat.

At this time, although the officers and soldiers of the torpedo cabin could not see the target, they knew it was definitely a big target.

The greater the displacement of a warship, the deeper the draft. For ordinary warships less than 10,000 tons, a fixed depth of 3 meters is enough. Now, with a fixed depth of 10 meters, it must be a big guy with a displacement of more than 30,000 tons!

Moreover, special torpedoes are used!

On U-47, dozens of torpedoes are equipped, but there are only two such G7U torpedoes. Generally speaking, only the most experienced submarines dare to carry such torpedoes.

This is a torpedo that has not existed in history. G, which means the caliber is 533 mm, 7, which means that the length is 7 meters, and the U behind it, which means hydrogen peroxide.

In this era, most torpedoes are electric torpedoes, and the technology has matured, and this kind of hydrogen peroxide torpedo is still a new thing.

The German torpedo also originated from an island country. When Cyrek visited the island country that year, he signed many projects, including the introduction of the island country’s Type 93 oxygen torpedo.

Oxygen torpedo is a kind of thermodynamic torpedo, but it uses oxygen instead of air to fully burn the fuel. Such torpedo has a longer range, faster speed, and great power.

Throughout World War II, only Japan used it for no other reason, because it was unstable.

Due to the relatively backward technical conditions and processing technology of the island country, the safety and reliability of this torpedo is compromised. The enemy warship killed and the own warship killed by the explosion are 1.5:1!

Therefore, other countries are discouraged. There is a serious accident probability that no submarine captain is willing to carry.

However, the United States was deeply impressed by the suffering of the nine-three torpedo, and organized a special force to develop two similar oxidizer torpedoes: MK16 and MK17.

At least because the successful development time was approaching the end of the war, in the end neither of these torpedoes were in service.

Cyric's crossing has brought a variety of foresight advantages. After the introduction of this oxygen torpedo technology from Japan, Germany did not immediately imitate it, but made great efforts to carry out a reliable transformation.

One of the key problems with the unreliability of Japanese torpedoes is that the collision fuze is too sensitive. After the use of magnetic fuzes, this problem was solved.

After several years of hard work, the current G7U torpedo, code-named T11, is already mature and can be carried by submarines.

Even if the safety issue is greatly improved, hydrogen peroxide is inherently unstable after all. Aircraft cannot be carried, and submarines now only carry a small amount of trial. For example, the current U-47 has only two such things.

After getting the order, the torpedo soldiers at the bow of the boat immediately became busy.

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

Only in the latter part of World War II did torpedoes have the means to adjust the depth at any time, and today's torpedoes must be adjusted before entering the launch tube.

Then, using slings and other devices, the shirtless torpedoes slid the torpedo into the front launch tube.

"Boom." Closing the launch tube, the torpedo head shouted loudly: "The torpedo is loaded and the depth is eight meters."

"Left rudder one." Prien continued to shout. If the torpedo is compared to a bullet, then his submarine is a gun. Especially when launching this special torpedo, there is only one way to go directly. He must To aim.

"Open the launch tube."

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

There are many ways to launch a torpedo, such as using compressed air to push it out, or you can fill the launch tube with water in advance to let the torpedo swim out by itself.

Now, it is the latter way.

"Target confirmation, war exhaustion, two G7U torpedoes, direct flight, three seconds apart, launch!" Prien shouted loudly.

emission!

The torpedo soldiers pressed the last button, and as the order was communicated, a terrible sound of water flowed between the launch tubes No. 1 and No. 2.

The mixture of hydrogen peroxide and alcohol enters the engine of this torpedo. It burns violently, driving the propeller at the tail, turning quickly, and swimming quickly from the torpedo tube!

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

The average electric torpedo can reach the limit of 30 knots, but this new type of torpedo can easily reach the high speed of 46 knots! The nine-three style in Japan can even reach 48 knots!

The hydrogen peroxide and alcohol burned, and the waste melted into the water. It was difficult to see any bubbles. The two torpedoes rushed to the huge battleship ahead.

At this time, the officers and soldiers of the War exhaustion were still trying their best to rescue the warship, closing the bottom compartment, and starting the drainage pump to pump out water. At this time, the hull had begun to tilt slightly.

At a depth of ten meters underwater, a 7-meter-long torpedo roared, and on the surface, nothing was seen!

The armor belts of warships are all distributed on the top, so the appropriate depth can allow the torpedo to avoid the armored single attack. At the same time, the difference of the fuze also makes the torpedo's attack depth different.

When there is no magnetic fuze, the target depth is generally set at about one meter less than the target draught, and it will directly collide and explode.

With a magnetic fuze, it would be one meter more than the draught ~www.novelhall.com~ It exploded at the bottom of the ship, using the water pressure generated by the explosion wave to lift the ship from the middle, so that it broke directly!

Of course, this kind of torpedo has a deeper set depth and has to pass through the bottom of the ship, which is one meter more than the draft.

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

But now, Prien didn't hide, he wanted to see the ending of War exhaustion in the periscope.

War-weary, with a standard displacement of 9.2 meters and a full-load draft of 10.35 meters, looking at the opponent now, it should be about nine meters in draft and ten meters in depth, which is just right.

In almost a minute, the huge torpedo got under the war exhaustion, and it was exactly as Captain Prien guessed. The torpedo was almost exactly one meter deep below the opponent.

"Boom!" The magnetic fuze detonated the 400 kg charge of the torpedo, and together with the hydrogen peroxide and alcohol that had not been burned, there was a violent explosion.

This explosion pushed the surrounding sea water, forming a huge water pressure, which pressed on the bottom of the war exhaustion. The surging sea water hit the middle of the war exhaustion. In this terrible impact, only one sound was heard. The twisted sound of soft steel from the roots of human teeth.

Then, the bottom of the war exhaustion was completely broken!
