Long Hao and Inzaji finished talking about the past, and then asked: "So many years have passed, have you taken over the order to build a submarine?"

"Build a submarine?" Inzaghi, a little drunk, raised his head and showed his white teeth: "Who is wasting money to build that thing? Wait, it seems, there is..."

Long Hao asked anxiously: "What's there?"

"Pa Ji", Inzaji, who was so drunk, actually turned his body and got drunk!

Why did Long Hao ask about the submarine? Because he bought the shipyard, not planning to build BB ships (battleships) or CV ships (aircraft carriers), but instead made his mind on the submarine!

Insert forcefully and give you some knowledge about submarines: In 1620 (early?), Dutch physicist Cornelis Derell successfully built the first submarine ship in human history.

The 'ship' is not called a 'boat', because this diving boat is more like a circular water ball, which can dive into the water for 3 to 5 meters.

However, in the next few hundred years, submarines did not make great progress. Perhaps the reason was that they could not use war. Compared with the strong ships and giant cannons, submarines were indeed in the eyes of the naval commander.

Too petty.

The first submarine, the Turtle, used for war, appeared in the American Revolutionary War in 1776. Although it did not achieve any results, it aroused widespread interest from many scientists.

I have to say that the pioneering spirit of the Americans is really amazing, so it is not unreasonable to become the world's largest country in the future. For example, Irish-American Fulton improved the "Turtle" number afterwards, 1801

In 1861, the construction of the submarine "Natutilus" was completed. By the outbreak of the American Civil War, the Southern Army first developed the submarine "Henlai" and sank the Northern Army's light cruiser "Houston", but because

The design of the 'Henlai' is inherently flawed and has poor longitudinal stability, so it was sucked by the water flow from the large hole on the 'Houston' side after the explosion, and finally died together.

Despite this, the example of the submarine defeating the warship for the first time still shocked the Northern Army, so the research project of the "Smart Whale" submarine that Inzaji participated in. However, after eight years of preparation, it was not small to invest at that time.

With a $50,000 study and construction funding, the Smart Whale still failed!

Long Hao only knows the history of these submarines. The one that impressed the most was probably the "unlimited" submarine warfare announced by Germany during World War I, and the "wolf pack tactics" of German submarines, which caused the then marine overlord Britain to suffer.

The heavy losses, of course, also attracted the participation of the United States in the war.

Now, after visiting Kunpeng Shipyard, Long Hao was surprised to find that he did not see any submarine, so he found an old boatman like Inzaji to ask.

In fact, Long Hao didn't know that although the submarine was born now, it was still a long way from its formation during World War I.

The reason? That's because there is a key person missing! Long Hao just can't remember this character for a while!

The next day, after Inzaji sobered up, Long Hao came immediately.

Long Hao asked with a smile: "Inzaji, you said last night that someone had built a submarine in our shipyard. Who is that person?"

In the dark, Long Hao felt that the person who placed the order was the key to finding him.

After hearing this, Inzaji looked embarrassed, and seemed to regret his words after drinking, and hesitated and refused to answer.

Long Hao was very good at dealing with foreigners. He snorted coldly and took out the Winchester revolver. Inzaji's wine immediately woke up, and the things he was holding in his stomach were like pouring beans on bamboo tubes.

I answered it in 510.

Hehe, I have to toast and not eat the wine!

Inzagi said: "That person is an Irish man. I heard that he has been engaged in submarine research since he was a child. About 6 years ago, I went to our shipyard to customize some special submarine parts because I happened to be free at that time.

So I did it for him privately, the amount was not large, it was only eight or eight hundred dollars..."

Long Hao laughed, no wonder this handsome Italian guy refused to explain, it turned out to be involved in the old case of his use of public interest and personal gain six years ago.

Long Hao waved generously: "That's a thing in the past, and it's a loss to the Trapatoni family. I don't blame you, continue talking!"

Inzagi breathed a sigh of relief and said, "This incident has been a long time ago, and I forgot it, but until three months ago, the Irishman came here again and entrusted me to make a submarine propulsion device. The money was really given.

Not much, only more than $2,000. For the sake of cooperation, I took the time to manufacture it for him. You know, if this propulsion device is put in a shipyard on the East Coast, it will definitely not be able to get it without $5,000.

Oh! This Irish guy is really cheap!"

Long Hao's eyes lit up and he asked, "What's his name for that Irish?"

Inzaghi said: "His name is John Holland, a slender old man with a gentleman. I heard that he is from Savannah, Georgia!"

It's him! Long Hao was excited: John Holland, this great man who is known as the founder of modern submarines!

John Holland was born in Liskena, Ireland in 1841. In 1873, Holland came to the United States alone with some submarine design drawings. In 1875, Holland dedicated his submarine plan to the United States.

The Navy was ready to use it to fight the British army, but Holland was rejected because the shadow of the failure of the Wisdom Whale Project that lasted for eight years had not yet dissipated.

At this time, Holland received the support of the Irish revolutionary "Fennia Society" who was in exile in the United States. After three years of hard work, in 1878, the submarine "Holland-1" was successfully launched.

In 1881, Holland, who continued to work hard, built the improved submarine, the Holland-2. The success of Holland 2 was to solve the vertical stability of the submarine that led to the tragedy of the Henry.

Sexual issues, he creatively invented a lift. When a submarine dives, it does not rely on increasing weight, but uses a submersible rudder (horizontal rudder) to maintain depth. When floating, it uses a small amount of reserved buoyancy to float up.

This design is considered an important milestone in the history of submarine development, but unfortunately, Holland is a pure researcher and has no idea of ​​using submarines for combat. One night, the staff of the Finnia Society took Holland.

No. 2 and Holland 3 were secretly transported away, but poor Holland was abandoned like a puppy.

However, Holland's love for submarines was crazy. Soon he found an artillery captain named Zallinsky to cooperate and built the fourth submarine, and named it the "Zallinsky", but the bad luck again

It landed on Holland. In 1886, Zalinsky was launched for the first time for experiments, but the slide collapsed and the entire boat was destroyed.

Now, Horan has parted ways with Zalinsky, living alone in Savannah, looking for generous people around the United States who are willing to invest in submarine research. He just received a sum and immediately found Inzaghi.

Manufacture this newly designed propulsion device.

The reason is just as Inzaji said, the manufacturing charges of Kunpeng Shipyards are indeed much cheaper than those of the United States' East Coast shipyards. Holland's choice here is also a helpless move to simplify and save money. After all, the shipbuilding industry on the East Coast

It is much more developed and the manufacturing process is far better than the West Coast. If there is extra money, Holland would not have traveled thousands of miles to San Francisco to customize it.
