For Yan Shao, if he can make a ship with a speed of about 40 knots, then even if Yan Shao pays a price of tens of millions or even hundreds of millions of yuan, it will be worth it.

Because such a ship will be very convenient for Yan Shao's travel in the future. Even if it is a voyage of 20,000 kilometers, it is only a matter of about ten days for Yan Shao.

There is no doubt about what this means in this era when aviation is not particularly mature.

This means that Yan Shao can complete many travel matters in less time than others. And as I said before, there are some things that can never be exchanged for time.

If such a ship can really be built, it will be worth it even if it costs more than 100 million.

And as I said earlier, in this era, no ship has ever reached a speed of more than 40 knots. So if you can really build such a ship, then even if there is no guard, the ship will not have any risk―――――― unless it encounters something like a storm, otherwise, it can only be dangerous if it sails into a place like the Strait of Malacca or the Strait of Gibraltar or the Suez Canal...

Because for a ship, the speed of more than 40 knots is already a very good self-defense measure in itself.

As I said before, what is the best precaution when dealing with torpedoes?

The correct answer is speed.

As long as you are faster than a torpedo, then naturally there will be no problem.

Again, as long as you're faster than a submarine. Then even if the other party wants to attack you, it will be difficult to catch up with you. It's just an ambush in front of your route. But there is also a premise, that is, you must know your route and time...

Ships at the moment. Usually the speed is more than 20 knots, and even cruisers and destroyers with very fast speeds are usually around 30 knots.

Considering that one nautical mile is equivalent to one kilometer and eight hundred and fifty meters, then 30 knots is equivalent to 55.5 kilometers, and the speed of a ship at 40 knots is equivalent to 74 kilometers, which is almost equivalent to almost 20 kilometers faster than a ship at 30 knots.

You can imagine how big the advantage is in terms of speed.

Of course, there are also some ships that will be faster, such as destroyers. These vessels usually reach speeds of up to 30 knots. Just like the Yamakaze-class destroyers equipped by the Wehrmacht Navy, they have a standard displacement of 1,300 tons and a full load displacement of 1,500 tons. It has a total length of 103 meters, a width of 9 meters, a power of 34,000 horsepower, and a design speed of 36 knots. In every sense of the word, it is a very good destroyer.

Of course, no matter how good it is, it is still many years ago, even when the national government was just established. It's been many years.

Although in later generations, it was not uncommon for a weapon to be used for decades and then slowly improve it little by little. But now it is an era of rapid technological advancement, in such an era. The easiest way to do this is not to update a weapon that is already a bit outdated, but to change it to a more powerful one...

That's what the current Wehrmacht is doing. After the end of the First World War. Based on the experience gained during the Battle of Jutland, the Defence Navy has learned a lot. In addition, this time is a period of rapid development of various technologies. Naturally, the Defence Navy, which has these technologies, needs to build a new type of ship that is more powerful than the original Shanfeng-class destroyers.

This kind of ship is the [Aoyama]-class destroyer named the [Aoyama]-class.

As a replacement for the Shanfeng class destroyer. The Aoyama-class destroyers have powerful combat capabilities that the Yamakaze-class destroyers do not have.

First of all, after multi-faceted improvements, the standard displacement of the Aoyama-class destroyers has been increased from the original 1,300 tons to 1,500 tons, and the full load displacement has also been increased from the original 1,500 tons to more than 1,800 tons...

There is no doubt that the increase in displacement brings about an increase in volume.

This is still somewhat beneficial for the destroyer, especially if the power system can keep up. After all, the larger the volume, the more stable it will be at sea―――――― but don't think that this is to make the officers and men on the ship comfortable.

You know, the sea is undulating. If an ordinary destroyer is tossed and turned by the waves during the battle, it is conceivable that the destroyer itself will not be able to aim accurately at the target by that time.

In fact, in previous naval battles, the so-called how many rounds out of a hundred and so on, it doesn't mean that the gunnery of these guys is really bad to this point. Rather, it is because the environment of naval warfare and land warfare is inherently very different, especially the undulating sea surface, which makes it even more difficult.

And at this time, it is obvious that ships with large-caliber guns, if their own weight is not enough, can easily become wobbly on the sea surface due to the recoil of the guns.

On the other hand, if the ship is large enough, then this recoil will not seem so strong.

How to say it, it's like attacking a battleship with a large-caliber machine gun on a battleship of more than 20,000 tons. There is no doubt that no matter how much ammunition this heavy machine gun fired, I am afraid that there is no way to make the battleship move even the slightest.

Not to mention a large-caliber heavy machine gun, even a 75mm caliber naval gun, I'm afraid it may not have much impact.

On the other hand, if a thousand-ton destroyer were to shoot with 75mm guns, the impact would be apparent...

Moreover, it is definitely not an ordinary manifestation.

――――――――――――――――――――――――――

Of course, the increase in the displacement of warships in later generations may not be due to this reason.

Because many people know one thing, that is, the history of the development of warships in later generations has actually gone through a very strange stage. First of all, because of the emergence of missiles, large surface combat ships began to be phased out. Because these ships with missiles on board, even if they are smaller. It is also very lethal, in this case. Naturally, there is no need for those military powers to maintain large surface combat ships that are very expensive and expensive.

Because most of the time, a small missile seems to be able to do a lot of things.

It can be said that in the first half of the Cold War, except for special ships such as aircraft carriers, other ships were in a state of shrinkage compared with those during World War II.

Not to mention the battleships that once dominated the sea, even large cruisers may not be able to compare.

But then, things changed. That is, the size of the originally reduced surface ships began to grow significantly again.

One of the main reasons for the occurrence of this situation is the increase in equipment. For example, a series of devices such as radar. It takes a lot of space. And as the threat from the air increases, these surface ships also need to be more armed.

There is no doubt that the vertical launch system is a good solution and does not take up much space―――――― but this is not very occupied, and it is only relative.

As a result, the warships were getting bigger and bigger, and by the time Yan Shao crossed over, the Americans had already begun to build large combat ships of more than 10,000 tons. And Yan Shao's hometown of China has also begun to build a 10,000-ton region...

It can only be said. It's really a reincarnation.

――――――――――――――――――――――――――

In any case, the tonnage of ships has increased, but this is a trend that no one can change. The Aoyama-class is a combat ship born under this trend.

The displacement of the Aoyama class has just been said, and compared to the Yamafeng class. The biggest change in the Aoyama class is still in the weapon system.

The original Shanfeng-class armament was 3 150mm L50 single-barreled main guns, 2 front and 1 rear layout, plus a number of 75mm and 37mm rapid-fire guns as secondary guns. At the same time, the most lethal weapons on the destroyer were three triple 18-inch MK.IX torpedo tubes (457mm). The 9 torpedoes in the launch tube can be used to deal with the enemy not only laterally but also vertically. The destroyer was also equipped with several spare torpedoes.

The new Aoyama class is equipped with the same equipment as the original Yamafeng class. Both are 150mm L50 single-barreled guns, and they are also two front and one rear layout.

That's it. It doesn't seem like much has changed.

However, as mentioned earlier, the increase in the size of the ship also reduces the recoil caused by the use of the main gun...

In any case, as the size increases, the hit rate of the gun will increase more or less.

What's more, although the main gun has not changed, the other weapons have changed greatly.

In fact, the biggest change in the Aoyama-class destroyer is its versatility.

In fact, the early destroyers were basically used as large torpedo boats, which can be seen even during World War II in the original time and space.

Destroyers were always used as large torpedo boats, and then played a series of key roles and so on.

However, the current Wehrmacht has no intention of doing so.

Because the navy really intends to use it as a multi-purpose ship.

For example...

Anti-aircraft, anti-submarine or rather anti-ship ...

Mmmm, I'm sorry, I'll make up for it in the next hour!!
