The Second Reich: Beginning with the Prince of Prussia

Since the elder Anderson had seen what a submarine looked like, and had the corresponding drawings in his possession, Andrews tried to get him to start building it.

It took Anderson Sr. a month to successfully prototype a small submarine with a displacement of 30 tons.

Although the tonnage of this submarine is not large, it can dive to a depth of 150 meters, and can carry two crew members, one person is responsible for controlling the submarine, and the other can drop weapons.

Andrews equipped the small submarine with a torpedo tube, with 2 torpedoes in reserve.

This makes this submarine, although small, with a certain amount of real combat capabilities.

However, due to tonnage limitations, the number of torpedo equipment was not enough, and the number of crew members on the submarine was not enough.

So, it's imperative to scale up.

However, if the submarine is to be expanded, it will face a very serious problem, that is, the material used to make the submarine must be a special steel with very strong structure and can withstand seawater extrusion.

There is currently a lack of this kind of steel in the empire, although ordinary steel can also be used to make submarines, but the performance of the submarines produced will be relatively poor, and the maximum diving depth will not be too large.

For submarines, the maximum diving depth is a very important indicator in evaluating the performance of a submarine.

The greater the depth, the higher the survival rate of the submarine when evading the attack of surface ships.

Therefore, Andrews was reluctant to compromise on this matter.

"Your Highness, none of the few steel mills in the Empire are currently able to produce the strength of steel we need. "

Arnold, who was in charge of finding materials for construction, came back with not so good news after searching several steel mills across the country.

Andrews had expected this.

"Owner, if we can't find the right materials, will our construction work be put on hold for the time being?"

Old Anderson on the side heard Arnold's words and persuaded Andrews.

Without materials, it is naturally impossible to build submarines.

And the owners were not satisfied with the use of existing steel to build submarines, so they had to suspend it.

"It's okay, continue to build according to the original plan, and I'll solve the problem of materials!".

After letting everyone leave, Andrews turned on the trading system and searched for the kind of special steel suitable for building submarines.

The system lived up to his expectations, and he succeeded in finding a special material with a yield strength of up to 1,200 megapascals.

It's just that the price of this thing surprised him a little.

The price of this special steel is as high as 2,000 points per ton, which is almost $1,000 when converted into dollars.

If a submarine is calculated according to 1,000 tons, the price of purchasing special steel alone will cost at least $1 million.

And that's not even counting the losses in the construction process, and if you add that, the cost will only be higher!

Counting the construction costs, labor costs, and other weapons costs, the cost of a submarine may exceed 1.5 million US dollars!

Unlike later generations, the US dollar in 1885 was still very valuable, and the Dingyuan and Zhenyuan orders from the Second Empire in the same era only cost a total of 2.82 million taels of silver, equivalent to 1.85 million US dollars.

You must know that these two ironclad ships are both giant ships with a displacement of more than 7,000 tons, and the purchase price of the two ships is actually similar to that of a submarine!

This shows how outrageous the price of this steel in the trading system is.

"System, your thing is too expensive, can't it be cheaper?"

Andrews couldn't help but complain that he hadn't bought much in the System Trading Center since the crossing.

The cars he purchased before were sold to others, and the cost was borne by others, so he didn't care too much about the price.

But now, this thing is bought for his own use, and he has to care more about the price.

[The one selected by the host is the titanium alloy special material developed by the red woolly bear for the 705 nuclear submarine Alpha submarine in the 70s of the 20th century, the price is more expensive than gold, and the price given by the system is now very cheap, and the host can choose other products. 】

Ugh!

Listening to the system's words, Andrews was speechless for a while.

No wonder the yield strength of this material is so high, it turned out to be Lao Maozi's work against the sky.

Andrews, the famous name of the Alpha submarine, has heard of it, and since the day of its birth, this submarine has been called a product that transcends its time!

Compared to other submarines of the same era, the Alpha submarine was faster and descended deeper.

It can reach a maximum speed of 41 knots underwater and a maximum depth of 900 meters

Such a fast speed and such a large diving depth make this submarine an almost invincible existence on the sea.

The enemy had no means of threatening it, and even if they spotted it, locked it on with a sonar system, and attacked him with a large number of depth charges and torpedoes, they would not be able to do him any damage.

Because the maximum attack depth of torpedoes at that time was only 500 meters, and the speed was only about 45 knots.

After sensing the threat, the Alpha submarine can quickly dive to a depth of more than 500 meters, so that all the torpedoes fired by the enemy will lose their target and lose their effectiveness.

It stands to reason that such a powerful submarine should be vigorously built by the woolly bears.

If all of their submarine forces are like this, then what aircraft carrier formation and what ten major fleets of Eagle Sauce will be as vulnerable as a local chicken and a dog!

However, the price of this thing is really ridiculously expensive, and the price of its titanium alloy material is so high that even the deep-pocketed woolly bear can't afford it.

Andrews couldn't cry or laugh, and said in his heart that his vision was so good, and he chose such a good material at once.

No wonder the price is so outrageous!

Considering that most of the submarines they are building at present are experimental in nature and are not really used in real combat.

So there is no need to be so extravagant and buy such good materials.

When the war really breaks out, it's not too late to buy this material to build a supersubmarine.

So, Andrews listened to the advice of the system and abandoned this titanium alloy material.

Another special steel, which is much cheaper, was chosen.

The yield strength of this steel is about 750 megapascals, and the maximum diving depth of submarines built with it can reach about 320 meters, which is roughly equivalent to the standard of steel used by submarines in various countries in the sixties of the twentieth century.

Although there is a big gap with the top materials, it is definitely enough for submarines of this era.

Considering that its price is relatively cheap, it only costs 200 funds per ton, so the price of this material is quite affordable even for the large-scale construction of submarines.
