"How far are you from your destination?"

After a brief wash, Otowa returned to the bridge.

The Lori's are still working in an orderly manner, in fact, when the crew has the same consciousness, the significance of the captain is actually not very big.

"8000 nautical miles, commander. ”

The one who reported to Otoha was still the maid Lori from last time.

"At the current rate, will it take a month......

Thinking of this, Otowa couldn't help but sigh.

The Type 21 can be said to be one of the most advanced submarines now, but after all, it is still a product of World War II, and the surface cruising speed is only about ten knots.

Sure enough, it is still the deep-sea fortress of the Federal Army, the nuclear fusion furnace + magnetohydrothruster can be used for 200 knots at will, and the voyage of 8,000 nautical miles can be completed in less than two days.

"There's no way around it, because there's not a lot of safe way to get to Antarctica. ”

The hatch behind Otowa was opened, and a purple-haired loli slowly walked out of it.

"But it's going to take a month......," Otowa said helplessly.

"Don't worry, it's going to be a very exciting month. ”

With a familiar voice, a silver-haired Lori with a three-headed body appeared in front of Otoha's eyes again.

Even though she has become a binding equipment for Otowa, Liz seems to still have the ability to manifest her own body...... Although it's still a three-headed body.

"What do you mean?"

When he said this, Otoha suddenly had a bad premonition.

Ding——

A familiar voice came from outside the ship, none other than the sound waves emitted by active sonar as it worked.

"It's a Nazi destroyer, we've been discovered!"

Chizuru's reaction was very fast, and she guessed the source of the sound wave at the first time.

"Turn off the silent cruise motor, start the electric motor, and go full throttle!"

"Understood. ”

Under Chizuru's order, the two electric motors located at the stern of the ship immediately ran at full power, increasing the speed of the propellers several times in an instant.

"Otowa, you go to the sonar officer's position. Chizuru took a deep breath, and then said quickly: "Think of a way to fuck the hell." ”

"Hey, I don't know how to use sonar. ”

Despite saying so, Otowa still walked to the position that Chizuru said.

"Whoever wants you to listen with your ears, mobilize your mental power. ”

"I'll try ......"

Otoha slowly closed his eyes, then pressed the sides of the earphones with both hands.

The original chaotic voice rearranged in Otowa's mind, and it didn't take long for it to turn into a three-dimensional battlefield map.

"The ships are now under your command, and there are still many torpedoes, so don't be stingy. ”

“OK。 Otoha nodded, and continued, "Hmm...... Tilt the bow up first, not too big, about 15°. ”

The sound of the pumping machine sounded in the cabin, the sea water in the front tank was slowly slapped out, and the bow of the submarine began to slowly tilt up.

The Lori's boating skills are very good, and Otowa said that 15° they really tilted the boat 15°, and there was almost no deviation.

"Turn right...... 36° Okay. ”

After only a moment's thought, Otowa gave instructions for the next stage.

In the map of the battlefield in Otowa's mind, her submarine began to turn again, and soon encased the destroyer on the surface into the attack envelope.

"Torpedo launch!"

Otowa did not hesitate and gave the order to attack directly.

Propelled by compressed air, two G7E torpedoes of 533mm caliber were quickly drilled out of the launchers in the bow.

The electric motor in the torpedo quickly worked, driving the tail propeller to a very high speed, allowing the two torpedoes to be sent at a very high speed towards the warship in front.

Although the German's electric mine is inferior to the book's perverted oxygen mine in terms of power, speed, and range, it is not without advantages, for example, there are almost no traces when this thing sails.

The Type 21 was the most advanced submarine of the Nazis, and the torpedoes carried were also the most advanced. The two G7Es that have just been shot are not ordinary goods, and they are all equipped with sound guide systems.

The early sound-guided torpedoes were actually unreliable, and there were many embarrassing situations where the launcher was destroyed after going around in a circle. But Otowa and the others didn't worry at all, because the destroyer that was conducting the underwater exploration was so noisy that they didn't have to worry about the torpedo finding the wrong target.

Although the trajectory of the electric torpedo was almost impossible to see when it was sailing, the sonar crew on the eviction was not disabled, and the sound of bubbles when the torpedo was fired was detected at the first time.

The Z-drive immediately accelerated, and at the same time made an evasive maneuver, but it was still too late.

If it was an ordinary torpedo, it might have been dodged by this thing, but unfortunately it encountered a top-of-the-line torpedo that cost a lot of money.

In addition to the sound guidance system, the G7E torpedo was also equipped with a magnetic fuse, which detonated the charge inside the torpedo without a direct hit.

Even without a direct hit, the torpedo detonated at extremely close range still caused serious damage to the enemy ship, directly opening a big hole in the waterline of this Z-drive.

The Germans developed sound-guided torpedoes to protect submarines, and now they are coming in handy...... It's just that it's their own expulsion that is blown up.

Not to mention continuing to pursue Otowa and them, this Z-drive is now a problem for self-preservation.

"Enemy ships lose power...... One more shot and they're screwed!"

Through the three-dimensional map in his mind, Otowa quickly analyzed the damage to the enemy ship on the sea.

"Then don't give them any chance, load the torpedo right away. Chizuru said with some excitement.

In addition to the powerful torpedoes on board, the quality of the Type 21 submarine itself is also very good. Using the hydraulic torpedo reloading equipment, the loli in the torpedo compartment quickly loaded a new round of torpedoes.

"Fire!

The two torpedoes had just been stuffed into the launcher before they were shot out, and they stayed in the torpedo launcher for no more than 10 seconds.

Although the sonar crew on the destroyer heard the sound of torpedo firing, they were now powerless, and the broken Z-drive could not move at all.

Knock –

The sound of the torpedo explosion was so loud that even the girls in the submarine could hear it.

The destroyer in Otowa's mind was gone, and if she was not mistaken, it must have been blown to pieces, sinking so fast that she didn't even feel it.

For a destroyer with a small tonnage, the torpedo is really a dead and injured if it hits.

"There should be a lot of Nazis coming to pursue, it's time to slip away. ”

Chizuru did not float up to confirm the results, but chose to run away.

Sometimes curiosity can kill people, and it's better to keep a low profile at this juncture of escaping.
