"Submarine", a key player in the tactics of the wolf pack.

It is also Zhang Zongqing's determination that China should develop a maritime force in the short term in the future.

Asymmetric strategy!

Even in another period of history, in order to deal with the threat of certain powers, China has vigorously developed "submarine" tactics.

It can be said that at that time, the performance and tactics of the "submarine" in China could be called one of the best in the world.

As for the study of China's "submarines", Zhang Zongqing is also involved.

The proposal of the "wolf pack tactic" made the students of the Fengtian Military Academy fall into a feverish discussion.

The more detailed the discussion of the "wolf pack tactics", the more shocked and shocked these students felt by this tactic.

Zhang Zongqing looked at the enthusiastic students and was very satisfied.

Just as he was about to say something, a familiar voice appeared in his mind.

Zhang Zongqing only felt that his eyes lit up, and the whole person seemed extremely excited.

"Ding, the super military design system gift package has been delivered, whether the host will receive it."

"Receive!"

Zhang Zongqing did not hesitate at all, he was a little curious about whether the gift package sent by the system this time was exactly what he wanted.

Over the years, Zhang Zongqing found that the weapon design drawings he needed, the system always seemed to be able to send them directly to him in a timely manner.

Sure enough, Zhang Zongqing's voice had just fallen, and the voice of the system soon came.

"Congratulations to the host for obtaining the design drawings of the U-XXI submarine made in country D."

"Host receiving, please!"

As the system's voice fell, a golden light suddenly flashed into Zhang Zongqing's mind.

The detailed details of the design drawings of the U-XXI submarine made by country D are like a movie, clearly appearing in front of Zhang Zongqing.

As the most advanced submarine in World War II.

The U-XXI submarine of the D country can be said to be the naval machine at the bottom of the pressure box of the D country, if it were not for the insufficient number of U-XXI submarines.

It may even reverse the maritime power of country D with the country of eagles and the country of rice.

Thus affecting the direction of the entire battle situation.

It can also be seen from this that submarine tactics have cast a big shadow on the two naval powers, Eagle and the United States.

And now, Zhang Zongqing has obtained the design drawings of this cutting-edge weapon.

How could he not be excited?

"Instructor Sa, you can help me bring paper and pen!"

"I've got a new gadget, show you!"

Sa Zhenbing was a little confused, but Monk Wei quickly reacted.

His eyes lit up, and the paper and pen were placed on the desk of the lectern in an instant.

"Brothers of the guard company, guard the door of the classroom of the Naval Academy, and no one is allowed to break in on their own!"

"Students, the design drawings that appear in front of you today must not be leaked in the slightest, the weapon designed by the second prince will be the killer weapon of our country, and it is a cutting-edge weapon that will be coveted by all countries."

Following Zhang Zongqing for so many years, Monk Wei naturally quickly understood what Zhang Zongqing wanted to do.

So he reacted very quickly.

"Could it be that the second son, the second son has designed a new weapon? I heard that every time the second son designs a weapon, he draws on the spot and has a flash of inspiration! ”

"Could it be a new weapon for our navy? A new weapon that leads the world? If the second prince really designs a new naval weapon that leads the world, then we will have enough confidence to confront the naval fleet of the Japanese slave country! ”

"I guess it's a naval submarine, after all, what the second son explained to us today is submarine tactics. This shows that the second son has long studied the submarine in his heart, and if the submarine really appears, then we can put the wolf pack tactics of the second son into actual naval warfare. ”

"If the second son really designs an advanced submarine that leads the world!" There were naval cadets from the Fengtian Military Academy, who squeezed their hands tightly with excitement on their faces.

"If we really design a submarine that leads the world, once the Japanese people dare to attack China, then we can use submarines to limit the naval power of the Japanese slaves!"

"Let them tremble and fear for our ghost troops of Huaguo!"

The students were excited by the scene in front of them.

They even held their breath and looked at Zhang Zongqing, who was engrossed in drawing the submarine design in front of them.

Rustle rustle......

Between heaven and earth, there seems to be only one voice.

Zhang Zongqing drew the design drawings that appeared in his mind on the blank paper little by little.

Standard graphical drawing, detailed coefficient references.

If before, the cadets of the Fengtian Military Academy were just excited.

When the entire design drawings of the D-made U-XXI submarine were presented in front of everyone little by little, their faces slowly changed.

They are all top talents from the Naval Academy, and they have in-depth research on the world's top warships and submarines.

But any submarine that appears in this world, in terms of performance and design, is still fully crushed by the submarine in front of him.

Where is this just a diving weapon under the sea?

This is simply a ghost, a fierce beast hidden at the bottom of the sea, as long as they open their fangs and completely shred any warship that appears on the surface of the sea.

With the help of such an artifact, it is not impossible to block the navy of the Japanese slave country in the Japanese slave country.

It was a type of diesel-electric submarine designed and used by country D during World War II.

The U-XXI submarine can be called the world's first truly "submarine" boat.

Snorkels, hydropressure-controlled depth fixing devices, semi-automatic ** filling systems, improved underwater listening devices, sonar, radar warning receivers, radars, and the elimination of deck guns and external ** storage boxes and other designs, the U-XXI submarine is completely invisible in the ocean.

Today, radar technology, as well as the large-scale application of sonar, make it not too difficult for warships to search for submarine targets under the sea.

And the U-XXI submarine overcame this problem, that is, the U-XXI submarine completely became a ghost hidden at the bottom of the sea.

Once this ghost, show its fangs.

The warships on the surface of the water will be completely swallowed by this underwater beast.

Therefore, when the design drawings and relevant performance parameters of the U-XXI submarine were presented in front of the naval cadets.

This kind of shock, the excitement it brings to people, is simply difficult to describe in words.

"Whew!"

When Zhang Zongqing finished drawing the last stroke, the relevant performance parameters of the last submarine were transcribed on a blank piece of paper.

Everyone only felt that their minds were buzzing, and the instructor of Sa Zhenbing even picked up the design drawings on the table with trembling hands.

He looked at the drawing, and his breathing became rapid.

"Second son, is this our future submarine in Huaguo?"

"This ...... This ......"

"It's the work of God!"

The instructor of Sa Zhenbing looked at Zhang Zongqing and praised from the bottom of his heart.
