Military: I came from a different world during World War II to make equipment

Chapter 113

Before the U-boat, other submarines in the world could not even be called submarines.

The reason is simple, those submarines always need to float on the surface of the sea to breathe air.

It is precisely because of these characteristics of submarines that this has led to the attitude of various countries towards submarines as if they were chicken ribs.

It's a pity to discard it if it's tasteless!

Some countries even use submarines as a means of transporting supplies.

However, due to the fact that the silence effect of submarines in some countries is really too poor.

In this case, the submarine is almost non-existent.

However, starting with the U-boat, the submarine of mankind, this can be regarded as truly entering a new era.

As the world's first real "submarine" boat.

The U-XXI submarine is a type of diesel-electric submarine designed for potential underwater patrol and combat.

For the first time, a snorkel device was used, which realized the transformation of the basic performance of submarines to underwater navigation.

The boat can reach an underwater speed of 17.5 knots and a silent speed of 6.1 knots.

If the U-XXI submarine has a cruising speed of 5 knots, it can even sail underwater for 2-3 days, so the submarine is several times more numerous than previous submarines in all aspects.

This is mainly due to the fact that the battery capacity of the 1,800-ton XXI submarine has been expanded to more than three times that of the Type VII submarine.

Because of the huge storage capacity of the U-XXI submarine, the U-XXI is also known as the "deep-sea electric shark".

In addition, the U-XXI submarine has six torpedo tubes in the bow and 23 torpedoes.

Its torpedo hydraulic loading system can load 6 torpedoes in 12 minutes, and 18 torpedoes

in 20 minutes.

On the other hand, on Type VIIC submarines, it takes 10 to 20 minutes to load a torpedo.

Moreover, the XXI submarine did not have to retreat to a safe sea area to reload after firing all the torpedoes in the launch tubes, as in the old model.

In addition, the submarine had two 20mm deck guns on its deck.

This allows the U-XXI submarine to fight against the ships on the surface even if it is on the surface.

The Type XXI submarine can have a cruising time of 1.5 hours at 18 knots, 12-14 knots and 10 hours at 10-14 knots, and up to 5 hours at a silent speed (with a cruising motor).

Tough performance, excellent evasion.

The U-XXI submarine was supposed to shine, but it was only produced at the end of the war.

This gives the U-XXI submarine a sense of heroic uselessness.

However, this U-XXI submarine fell into the hands of Lin Changxin, and Lin Changxin certainly would not let the U-XXI submarine be dusted.

At present, the naval strength of the Beifu Army is far inferior to the naval fleet strength of the Sakura Sword Country.

Taking advantage of the powerful performance characteristics of the U-XXI submarine will not only be able to strike a blow to the naval strength of the Sakurato Country, but will

also be able to gain the advantage of this asymmetrical battle.

It can even give Lin Changxin

and the Beifu Army time! Let the Beifu Army build a powerful fleet! The Beifu Army

and the Great New Kingdom need time, and they will not be able to build a powerful naval warship in a short period of time.

The U-XXI submarine is precisely the most suitable and the best weapon.

"In this way!"

"There are some guarantees for China's sea and airspace!" Lin

Changxin said to himself.

"Young marshal

!" "It's here!" Li

Jinguo said this, and Lin Changxin reacted.

He pushed open the door and stepped out.

......

Since Lin Changxin left Mingcheng, he has been fighting outside.

Now that the situation has finally calmed down, Lin Changxin can finally take some time to accompany his old father and his family.

After Lin Changxin vigorously promoted the anti-smoking campaign, the entire three northern provinces and regions took on a new look.

Lin Changxin's three younger brothers have also successfully quit their addiction to smoking, and compared with their previous debauchery and misdeeds, they are now much more pragmatic.

Especially Lin Changxin's second brother Lin Ziliang, after quitting his addiction to smoking, Lin Changxin sent Lin Ziliang to the grassroots area.

This is not Lin Changxin's attempt to suppress his second brother so that he cannot pose a threat to his position.

To be honest, Lin Changxin didn't care about these at all.

If his younger brother is really promising, Lin Changxin will be even more pleased.

After all, at the end of the day, they are all their own relatives.

Even if Lin Changxin once broke their legs, he just wanted to give them a lesson that he would never forget.

None of the prodigals were able to clean them up and give them a lesson they would never forget.

I'm afraid that their whole lives will be ruined!

Now, judging from the letter his father gave him, his second brother has performed quite well.

In the process of poverty alleviation in grassroots areas, his younger brother has experienced the hardships of the people and faded away from his youthful frivolity.

It's gradually stabilized, and I have the feeling of a real manly man.

The car stopped in front of the Marshal's Mansion, and Lin Changxin stepped down from the car.

He walked towards the inner room, and after walking a few steps, Lin Changxin heard a burst of laughter like silver bells coming from the courtyard.

Lin Changxin smiled lightly, and he walked towards the place where the voice came from.

Walking to the place where the voice came from, Lin Changxin saw his second brother Lin Ziliang holding his daughter Lin Zi'er and teasing.

The one who just let out a silver bell-like laugh was Lin Changxin's second brother Lin Ziliang's daughter, Lin Zi'er.

"

Daddy!" "Daddy, Uncle is here!" "Uncle is

here!" Lin Zi'er said to her father with a smile on her lovely appearance.

Lin Ziliang saw Lin Changxin walking towards this side, and looked a little restrained.

After all, his eldest brother Lin Changxin left him a shadow that would be difficult to erase in his life.

Although Lin Ziliang has completed his transformation, he will not be able to get rid of this shadow for a while.

Of course, Lin Changxin knew what Lin Zi's conscience was thinking.

He took the initiative to smile at Lin Ziliang, which eased the embarrassment.

Then, Lin Changxin bent down, "Zi'er

!" "Come here

!" "Uncle will give you candy!" After speaking, Lin Changxin took out several candies from his pocket.

When the little girl saw it, her eyes were straight!

She stepped away and ran quickly in the direction of Lin Changxin.

"

Uncle!" "Uncle!!"

The little girl threw herself into Lin Changxin's arms.

When Lin Changxin just wanted to praise the little girl, he found that a few candies in his hand were missing.

"Uncle, you're so good!" the little girl slapped a rainbow fart at Lin Changxin.

Lin Changxin was stunned for a moment, and then laughed.

"Hahaha

!" "Hahaha

!" "Zi'er, you little clever ghost!" Lin

Changxin was also amused by his eccentric little niece.

When everyone saw this scene, they also laughed.

For a while, the atmosphere was still a little tense just now.

Instantly relaxed.

There is a hint of family feeling in the marshal's mansion.
