The Nazi Antarctic base was almost replenished by submarines, so several flagships can be seen in the port almost every day.

When Otowa and the others attacked the Antarctic base, there happened to be several submarines unloading here, and several submarines were also undergoing overhaul in the nearby maintenance station. There is no suspense that these submarines eventually fell into the hands of Otowa and the others.

"We're going to use these submarines to fight the Nazis in a moment?"

Otowa who was walking in the corridor of the Type 21 submarine suddenly spoke to Chizuru beside him.

"That's right. Chizuru nodded, and continued, "Those tanks and planes are our secret weapons, and now is not the time for them to be unveiled, so we have to use the existing equipment to deal with the Nazis." ”

The corridor of the Type 21 submarine was not very long, and before the two had time to say a few more words, they both came to the command room of the submarine.

"That's a lot of warships sent by the Nazis, Chizuru. Otowa tilted his head.

"I know. Chizuru sat down in the captain's seat, then said with a smile, "These submarines have all been modified by us, and they are all equipped with 'big killers'. ”

"Oh?"

Although I don't know what the "big killer" Chizuru is referring to, looking at her confident appearance, she shouldn't disappoint Otowa when the time comes.

"Otowa, that seat is for you?"

"What is this?"

The direction that Chizuru was pointing to was no stranger to Otowa was exactly where the sonar crew was, where Otowa had fought on this submarine before.

However, unlike last time, this time there is an arcade stick-like device on the table, and I don't know what this thing is used for.

"This is a wire-controlled torpedo operator, made for you. Chizuru said with some smugness.

"I see......"

This kind of manually controlled torpedo is indeed not good for ordinary people, but for Force soldiers who have their own battlefield maps in their heads...... This thing is an artifact that hits every shot!

Thinking of this, Otowa couldn't help but look forward to the next battle.

……

The hatch of the base located under the waterline slowly opened, and six U-boats of different types drove out from here one after another.

In World War II, submarines were generally slow underwater, making it difficult to catch up with ships on the surface, so ambush tactics were generally used to attack.

With Lisi's help, Otowa and the others were able to figure out the Nazi route without much trouble, and then set up an ambush in the path of the enemy fleet.

"Liz's information is correct, I feel it...... There is a large fleet approaching. ”

Just when everyone was a little tired, Otowa who was sitting in the sonarman's seat suddenly stood up.

The sea was pitch black at night, and Lori, who was in charge of using the periscope, couldn't see anything at all. But Otowa can find enemies with mental power, and I have to say that Force warriors can really do whatever they want.

"Finally...... It's coming!"

Chizuru, who was napping, instantly came to her senses, and then put the captain's hat on top of her head.

"Load the heavy torpedoes, I'm going to teach them a good lesson!" Otowa said with some excitement.

"Yes!"

As soon as the loli in the torpedo compartment received the order, they filled a heavy torpedo into the launch tube.

The big killer that Chizuru is referring to are these torpedoes that are clearly different from the G7E.

While weapons made with modern technologies are not yet useful, ammunition made with modern technologies does not have this limitation.

These torpedoes are powered by a thermodynamic swash plate machine, using Otto 2 type fuel, with a system power of 500 horsepower, high energy density, low noise, no wake and other characteristics, and can travel more than 50 kilometers at a speed of more than 40 knots

The torpedo warhead is a blasting warhead with a charge of 100-150 kg, which can sink a large submarine or medium surface ship with a single mine hit.

To put it simply, this is the MK.48 of a thousand crane copycats.

"Torpedo launch!"

Gollum –

Propelled by high-pressure air, four heavy torpedoes of 533mm caliber broke away from the submarine.

Each of these torpedoes has a wire behind her buttocks, and the operation of the Otoha will be converted into an electrical signal by the joystick in front of her, which will then be transmitted to the torpedo through these wires.

These torpedoes advance at a speed of 50 knots, or 1.5 kilometers per minute, and had to travel a long distance to reach their target.

Otowa maintained his highest concentration in the process, for fear of losing the torpedo's position due to distraction.

It was only after about 10 minutes that Otowa slowly raised his hand and held the joystick in front of him tightly.

The image of the enemy fleet was so clear in Otowa's mind that she was even able to distinguish the type of warship to a certain extent, and then guide the torpedo to hit the most valuable targets.

The MK.48 of Chizuru Cottage is difficult to spot during the day, let alone at night. Just without the complete knowledge of these Nazis, a torpedo slammed into an enemy ship.

There was a violent explosion from the aircraft carrier in the center of the procession, and the entire ship was lifted up by the force of the explosion, and it took a while to regain its position.

The power of this torpedo was so terrifying that a huge opening was made in the waterline of this aircraft carrier on the spot, directing the icy sea water in.

After letting a torpedo hit the target, Otowa did not hesitate and immediately guided the next torpedo.

Needless to say, this torpedo was also aimed at the aircraft carrier in the center of the fleet, that is, the most valuable target in the Nazi fleet.

After being hit by a heavy torpedo, the aircraft carrier had already begun to tilt to one side, apparently receiving serious damage.

However, before the ship's damaged pipe could be rescued, the ship shook violently again.

A loud explosion spread throughout the fleet, and almost all the crew members on deck could hear it.

The power of heavy torpedoes was quite terrifying, and after two such hits in a row, the aircraft carrier of tens of thousands of tons immediately began to capsize.

Although the warhead was only about 100-150 kg, Chizuru used a future high-energy explosive for this torpedo, which is not known how many times more powerful than ordinary TNT.

Rather than allowing the remaining torpedoes to continue attacking the doomed carrier, Otowa left it to find another target.

Before the Nazis could figure out what was happening, two explosions were heard in quick succession in the fleet.

This time it was two heavy cruisers that suffered, and this heavy torpedo with a displacement of tens of thousands of tons was still vulnerable in front of it, and it was blown in two almost instantly.

In the first round of torpedo attacks alone, Otowa achieved more than 50,000 tons, and I have to say that the torpedoes made by Chizuru are really terrifying.
