Therefore, the most important thing is to not raise the indicators too high. To make the submarine have the ability to navigate underwater for a long time. Reducing navigation in the snorkel state can more effectively avoid danger.

The advantages of Stirling engines are high efficiency, low noise, low pollution, and low operating costs. However, Stirling engines have relatively small power, so they are generally used to drive submarines to navigate slowly underwater.

It is just like adding such a cabin. Once high-speed navigation is needed, the original technology is still required.

Cialek put forward low requirements for various indicators, which also played a catalytic role in the invention of this machine. In two years, Germany should not have a large-scale military conflict with the United States. Cialek needs time to buffer and first solve the Soviet problem.

At this moment, at the other end of the earth, a duel between submarines and surface ships had just begun.

Above the Pacific Ocean, the blue waves are rippling, and the waves are less than one meter high, which is a good time for sailing.

A large submarine is sailing on the sea in a floating state. For the submarine soldiers, it is already very good to be able to breathe the wet sea breeze.

This submarine is not small in size, with a total length of more than 100 meters and its underwater displacement exceeds 2,400 tons. It is definitely a big guy among the submarines.

The front end of the hull is painted with a crooked Yi-74 hull number.

Yes, this is the latest Haida 6b submarine to be put into service by the island country's navy!

The submarines of the island country are named "Yi, Lu, and Bo" after being divided into large, medium and small sizes. They are similar to the A, B and C in Chinese. The submarines of Yi belong to the first-class submarine with a standard displacement of more than 1,000 tons. A few years later, the navy of the island country has built a large guy with a displacement of 3,000 tons or even 5,000 tons.

A submarine soldier climbed up from the command tower in the middle. He was not tall and yellow-skinned. He spoke in his whispering birds, and then held a sun flag in his hand.

He climbed up and wanted to hang the sun flag on the mast above the command tower, but, just as he was about to pull the rope, suddenly, a gust of sea breeze blew, and the sun flag was blown into the sea by the sea breeze!

The birds singing below continued to be heard, roughly saying to the other party’s women in their homes and expressing their intimate contact with the other party’s women. Moreover, this is a kind of charity, and they do not dislike the other party’s ugliness.

"Sanlang, you idiot, why did you throw the flag into the sea?"

"Report, I accidentally go get another new one."

"This is the last flag!"

"terribly sorry."

"Sorry, I'm a bird. Take your sheets and draw the national flag with paints. Let's hurry!" The voice below was even more dissatisfied.

"yes."

The idiot Saburo ran to his cabin, and soon, a colorful flag was hung out.

"Idiot, why don't you use red?"

"There is no red pigment, only black ink."

"Baga, slap!" Several big slaps hit Sanlang in the face, and a few times, bleeding came out of his nose.

"There's red now, draw it!"

After a lot of trouble, it took half an hour to finally, the bed sheet, mixed with black paint and red blood-stained flag, was hung up and fluttered violently in the wind.

Blocking his nose, Saburo continued to stand on it. Now, he was going to be a lookout, which was a glorious and sacred mission.
