Chapter 402 Hydrogen Peroxide Torpedo

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

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

The larger the displacement of the warship, the deeper the draft. For a normal warship within the 10,000-ton class, 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, the use of special torpedoes!

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

This is a torpedo that has never been seen in history, where G means the caliber is 533 mm, 7 means the length is 7 meters, and U at the back means hydrogen peroxide.

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

The German torpedoes also originated from the island country. When Cyric visited the island country, he signed many projects, including the technology introduction of the Type 93 oxygen torpedo in the island country.

Oxygen torpedo is a kind of thermodynamic torpedo, which just uses oxygen instead of air to make the fuel burn fully. 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 have been compromised.

Therefore, other countries are discouraged, and no submarine captain is willing to carry the serious accident probability.

However, the United States was deeply impressed by the suffering Jiusan torpedo that year, and organized special forces to develop two similar oxidant (hydrogen peroxide) torpedoes: MK16 and MK17.

At least because the successful development time was nearing the end of the war, both of these torpedoes failed to serve in the end.

Cyric's crossing brought various advantages of foresight. After the introduction of Japan's oxygen torpedo technology, Germany did not imitate it immediately, but made great efforts to improve the reliability.

One of the key problems with the unreliability of this Japanese torpedo was that the impact fuze was too sensitive, and this problem was solved with the introduction of the magnetic fuze.

After several years of hard work, the current G7U torpedo, codenamed T11, is mature enough to be carried by submarines.

Even with great efforts to improve safety, hydrogen peroxide is inherently unstable after all, and cannot be carried by planes. Submarines now only carry a small number of trials, such as the current U-47, which only has two such things.

After receiving the order, the torpedo soldiers at the bow immediately got busy.

Using a special wrench, twist the mechanical depth-fixing device of the torpedo, and the sound of the spring twisting came from inside, and soon, it was set to a position of ten meters.

Only in the late World War II did torpedoes have the means to adjust the depth at any time, and the current torpedoes must be adjusted before entering the launch tube.

Then, using devices such as slings, several shirtless torpedomen stuffed the torpedoes into the launch tube in front.

"Boom." After closing the launch tube, the torpedo officer shouted loudly: "The torpedo is loaded, and the depth is fixed at eight meters."

"Left rudder one." Prien continued to shout. If torpedoes are compared to bullets, then his submarine is a gun, especially when this special torpedo is to be launched, there is only one way to go straight, he must To aim.

"Open the launch tube."

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

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

Now, it's the latter way.

"Target confirmed, Warspite, two G7U torpedoes, go straight, three seconds apart, launch!" Prien shouted loudly.

emission!

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

The mixture of hydrogen peroxide and alcohol entered the engine of this torpedo, burning violently, driving the propeller at the tail, turning it quickly, and quickly swimming away from the torpedo tube!

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

General electric torpedo, Biao to 30 knots is the limit, and this new type of torpedo, it is easy to Biao to 46 knots high speed! And Japan's Nine-Three Style can even go up to 48 knots!

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

At this time, the officers and soldiers of the warspite were still trying their best to rescue the warship, closing the cabin at the bottom, and starting the drainage pump to draw out the water. At this time, the hull of the ship had begun to tilt slightly.

Ten meters deep underwater, a 7-meter-long torpedo came whizzing, but on the surface, nothing could be seen!

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

When there is no magnetic fuze, the general setting depth is that the target draft is about one meter less, and it will directly collide and explode.

With the magnetic fuze, it will be one meter more than the draft, it will explode at the bottom of the ship, and the water pressure generated by the explosion wave will be used to lift the ship from the middle, so that it will break directly!

Of course, this kind of torpedo is relatively deep, and has to pass through the bottom of the ship, that is, one meter more than the draft.

If it is under normal circumstances, after the submarine launches the torpedo, it must immediately dive and get away. After all, once the fire is fired, the other party will know its existence and can escape as far as possible.

But now, Priyan didn't dodge, he wanted to see the end of Warspite in the periscope.

Warspite, under standard displacement, has a draft of 9.2 meters and a full-load draft of 10.35 meters. Now, looking at the other party's appearance, it should have a draft of about nine meters and a depth of ten meters, which is just right.

It took almost a minute for the huge torpedo to get under the Warspite, exactly as Captain Prien had guessed, and the torpedo was almost exactly one meter below the opponent.

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

This explosion pushed the surrounding sea water, forming a huge water pressure, pressing on the bottom of the Warspite. The surging sea water hit the middle of the Warspite. In this terrible impact, only a sound was heard. The sound of steel twisting with soft roots.

Then, the bottom of the Warspite was completely broken!
