The Second Reich: Beginning with the Prince of Prussia

After identifying this material, Andrews spent 100,000 points and bought 500 tons to come back for trial.

The funds on his system account are not enough, but fortunately, with the help of the system, he can top up with real world money according to a certain percentage.

Thinking that he would have to purchase goods from the system in the future, Andrews spent $10 million and recharged 20 million points.

After spending 100,000 points of money to buy these steels, I bought 10,000 Beetle cars at the price of 1,000 points.

He had received a deposit from Rockefeller for the first car order, and if you calculate the time, it should be delivered in the near future.

By the time these cars are sold, he will have more than $20 million more in his account!

If Rockefeller's estimate of the potential of the North American market is correct, he will earn at least $50 million from cars this year alone.

If you include the revenue of various other products, this year's income should be around $100 million.

With this money, many of his plans can be executed.

Looking at the special steel that Andrews brought back, the old Anderson and several other skilled workers in the shipyard were all shocked!

"Do these things work?".

Andrews chuckled at the sight of their expressions, and had a premonition that something was not right.

The better the quality of the steel, the more difficult it is to weld.

He only cared about picking up the good ones and bought them, but he forgot about the stubble.

If these people don't have the skills to process these steels, then they will buy these things for nothing!

"It should work, these things are much better than the steel we have seen before, it may be a little difficult to weld, but it doesn't matter, we have a few masters here, and their welding skills are excellent!".

Although the old Anderson said so, Andrews was still a little uneasy, so he simply spent some money to buy a few sets of advanced welding tools in the trading system and handed them over to these old welders.

These welders, all of whom are shipyard special-grade workers, are well-informed and experienced, and after seeing the benefits of the new equipment provided by Andrews, they are all full of praise for it.

At first, they were a little apprehensive about how to weld the new steel, but after trying out the new equipment, they were completely relieved

As a result, the work on the second trial submarine went smoothly.

Three months later, the second submarine with a displacement of 200 tons was launched.

Andrews personally attended the launching ceremony and named the submarine U-2.

Compared with the previous U-1 submarine, the U-2 submarine adopts a new double-layer pressure-resistant shell design.

This allows it to dive to a greater depth, capable of diving below 300 meters, and thanks to excellent materials and excellent welding technology, it can even reach a maximum depth of 350 meters.

In addition, with the increase in tonnage, its interior space has also increased a lot.

The U-2 submarine could carry a crew of 8 people, carried 3 torpedo tubes, and was equipped with 9 torpedoes.

The maximum speed at the surface is 25 knots, the maximum speed under water is 18 knots, and the cruising speed is 18 knots.

Due to the limitations of battery technology, the U-2 submarine could not be underwater for too long, like later submarines, otherwise the battery would use up the reserve power and the submarine's engine would have to be used to provide kinetic energy.

The engine needs to consume oxygen, and in the deep sea, there is no way to supplement oxygen, once the engine works, the submarine will soon lack oxygen, which will lead to the life of the crew.

Therefore, when the U-2 is underwater, unless it is attacked by enemy forces and needs to quickly leave the engagement area, in other cases, they will generally only maintain a minimum speed of 3 knots and sail slowly.

Compared with the U-1 submarine, the U-2 submarine has greatly improved its various technologies, and it has initially possessed actual combat capability.

But this is not enough, the volume of only 200 tons limits its combat potential.

With such a small tonnage, the weapons and fuel it carries are very limited, so it can only operate in the near sea, and cannot go to the ocean to fight.

And their future opponent is the Empire, the sea route on which the sun never sets is at least thousands of kilometers away from the mainland of the Second Empire, and to cut off these routes, the Endurance of the Empire's submarines must be at least more than 5,000 kilometers.

So Andrews immediately began planning for the construction of the U-3 submarine.

The success of the U-2 submarine made everyone involved in the development and construction of the submarine very happy, and coupled with the early award issued by Andrews, they could not wait to prepare for the next stage of the development of the submarine.

"Do you think we have a bigger submarine to build 500 tons or 1,000 tons, which one do you think you have a better grasp of?"

The greater the tonnage of the submarine, the more complex it is to build and the greater the difficulty it will be.

Taking into account the fact that the special steel they use is not cheap, the cost of a submarine is more than hundreds of thousands of dollars.

Therefore, they must do what they can, slowly accumulate experience, and not start with too high ambitions, if they fail, not only will a lot of money be wasted, but also have a great impact on the confidence of the designers and builders who participated in the development work.

At the beginning, the submarines of the Second Reich also went through a long research and development process, and only then did they develop step by step from small submarines to large, even intercontinental ocean-going submarines.

Although the current international situation is tense, the war will not break out for a while and a half, and they still have time to develop slowly, slowly accumulate experience, and do not need to be greedy for more and faster.

"With our current technical reserves, a submarine of 500 tons should not be much more difficult. "

Old Anderson was still steady, without any impatience.

"A five-hundred-ton one should be nine out of ten, and a submarine of this level is not too difficult, but it is of little significance to our training.

And 1,000 tons is a bit too difficult, and we should not be able to cope with it at our current capacity. "

Another designer spoke.

"Oh, what do you mean?".

Andrews glanced at the man who spoke, Jonathan Norfolk, a designer he had dug from the Austro-Hungarian Empire and specialized in submarines.

Jonathan took part in the second half of the development of the U-2 submarine and had a preliminary understanding of the strength of the Volkeng shipyard.

Coupled with the fact that he had seen those very good submarine design drawings provided by Andrews, he was full of confidence:

"I think, with a compromise, it would be best to build an 800-ton one!".

Eight hundred tons?

Submarines of this class were already the main submarines of the Second Reich during World War II.

In the early days of World War II, most of Dönitz's holdings were submarines with a displacement of less than 500 tons, and it was not until after the war that a batch of 1,000-ton submarines were built and launched.

However, with excellent submarine tactics, Dönitz still achieved very dazzling results in the war with these small boats in his hands.

After the mass service of the thousand-ton submarines, the submarines of the Third Reich became a nightmare for the Allies at sea!
