"No. 1, No. 2 launch tubes, G7U torpedoes, fixed depth of 10 meters, maximum speed. Pen ~ Fun ~ Pavilion www.biquge.info" Prion shouted loudly, his voice reaching the torpedo compartment in front of him through the intercom in the boat.

At this time, although the officers and men of the torpedo compartment 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, and for an ordinary warship within 10,000 tons, a fixed depth of 3 meters is enough, and 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 the U-47, several dozen torpedoes were armed, however, there were only two of these G7U torpedoes, and in general, only the most experienced submarines dared to carry such torpedoes.

This is a torpedo that has not been seen in history, where G, which indicates that the caliber is 533 mm, 7, represents a length of 7 meters, and U, which is behind, represents hydrogen peroxide.

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

When Shirek visited the island country, he signed many projects, including the introduction of the island country's Type 93 oxygen torpedo technology.

An oxygen torpedo is a kind of thermodynamic torpedo, which only replaces air with oxygen to allow the fuel to burn sufficiently, such a torpedo has a longer range, faster speed, and great power.

Throughout World War II, only Japan used it, for no other reason than 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 are reduced, and the enemy warship killed is 1.5:1 compared with the own warship killed due to self-explosion!

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

However, the United States was deeply impressed by the 93 torpedo, which suffered greatly, and organized special forces to develop two similar oxidizer (hydrogen peroxide) torpedoes: MK16 and MK17.

At least because the development was nearing the end of the war, neither torpedo was put into service.

After the introduction of this oxygen torpedo technology from Japan, Germany did not immediately copy it, but made great efforts to improve its reliability.

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

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

Even if a lot of effort has been made to improve the issue of safety, hydrogen peroxide is, after all, congenitally unstable, and cannot be carried by aircraft, and submarines are now carrying only a small number of trials, such as the current U-47, which has only two such things.

After receiving the order, the torpedo men in the bow of the boat immediately got busy.

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

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 launch canister.

Then, using chains and other devices, several shirtless torpedo men stuffed the torpedo into the front launch tube.

"Boom." Turning off the launch tube, the torpedo shouted loudly: "The torpedo is loaded, set to a depth of eight meters." ”

"Left rudder one." Prien continued to shout that if a torpedo was to be compared to a bullet, then his submarine was a gun, especially when it came to firing this special torpedo, and there was only one way to go straight ahead, and he had to aim.

"Turn on the launch tube."

The helmsman swung the rudder, the torpedo crews manually opened the launch tubes, and then the sound of the raging sea water was heard.

There are many ways to launch a 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 on its own.

Now, it's the latter way.

"Target confirmed, war weariness, two G7U torpedoes, direct flight, three seconds apart, launch!" Prion shouted loudly.

Launch!

The torpedo crews pressed the last button, and as the order was delivered, a terrible sound of water sounded at intervals in the No. 1 and No. 2 launch tubes.

Hydrogen peroxide and alcohol were mixed, entered the engine of this torpedo, burned violently, drove the tail propeller, turned rapidly, and quickly swam away from the torpedo tube!

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

The average electric torpedo is the limit when it soars to 30 knots, and this new torpedo can easily soar to a high speed of 46 knots! And Japan's ninety-three style can even soar to 48 knots!

Hydrogen peroxide and alcohol burned, waste melted into the water, it was difficult to see any bubbles, and two torpedoes rushed to the huge battleship in front of them.

At this time, the officers and men of the war-weary, still trying their best to save the warship, closed the compartment at the bottom, and activated the drainage pump to pump out the water, at this time, the hull had begun to tilt slightly.

Ten meters under the water, 7 meters long, a torpedo, whistling, and on the water, nothing can be seen!

The armor belts of warships are distributed on them, so the appropriate depth can allow the torpedo to dodge the single attack of the armor, and at the same time, the different fuses also make the attack depth of the torpedo different.

When there is no magnetic fuse, the general depth is that the target draft is about one meter less, and it will explode directly into the collision.

And with the magnetic fuse, it will be one meter more than the draft, explode at the bottom of the ship, and use the water pressure generated by the explosion wave to lift the boat from the middle, so that it will be broken directly!

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

If it is in an ordinary situation, after the submarine launches a torpedo, it must immediately dive and slip away, after all, once the fire is fired, the other party knows its existence and how far it can escape.

But now, Prion did not dodge, he was going to see the end of the Warweariness in the periscope.

War-weary, under the standard displacement, the draft is 9.2 meters, and the draft is 10.35 meters at full load, and now looking at the other party's appearance, it should be about nine meters in draft, and ten meters deep by itself, just right.

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

"Boom!" The magnetic fuse detonated the 400-kilogram charge of the torpedo, which, together with the unburned hydrogen peroxide and alcohol, exploded violently.

The explosion, pushing the surrounding seawater, formed a huge water pressure, pressing on the bottom of the Weathiness, surging seawater, hitting the middle of the Weathiness, in this terrible impact, only the sound of steel twisting that made the roots of the teeth soften.

Then, the bottom of the War Weary broke completely!
