With the full picture view opened and contacted organizations in other regions, this activity was very curious and surprising at the beginning.

But when the actual contact work begins, people who do not have the ability and interest in this area will gradually become bored.

Xu Xingchen fought in the scientific research center, and saw Shenzhen dealing with other ship girls in an orderly manner, he subconsciously yawned.

Seeing this, Shenzhen smiled and reminded:

"Commander, daily diplomatic work is very boring. You should go and rest, don't wait here..."

"No...I want to stay all night, I don't need to rest..."

Xu Xingchen subconsciously shook his head and waved his hand. He really wanted to wait for all the satellites to enter orbit. He didn't feel tired and really didn't need to rest.

At this time, you instinctively yawn, just like when you were in school, listening to lectures by teachers in advanced mathematics or math, and you immediately became energetic after class...

Xu Xingchen, who understood this truth in his heart, immediately found something that interests him, looked at Yamato beside him and said:

"I'm just free now, and I'm idle anyway. Call Musashi, Shoto and the others over, and I'll make the transformation for you first..."

Yamato also went over to discover the excitement of other regional ship girls organizations. When he heard Xu Xingchen's ship girls, he immediately became energetic:

"Okay, so good, we've been looking forward to it..."

Xu Xingchen said goodbye to Yuanwang 1, Neptune and Shenzhen, and took Yamato to the room in the lounge area below.

Yamato sent a message to Musashi and others, and at Xu Xingchen's request, he lay down on the bed again, waiting for Xu Xingchen's actions.

Unlike the last transformation, Yamato's mentality has changed now. He smiled and watched Xu Xingchen sit down beside him. His instinctive resistance and vigilance have completely disappeared.

Xu Xingchen entered the system interface, looked directly at Yamato in front of him, tried to open the interface of her hull modification, and went in without any obstacles.

Xu Xingchen smiled in his heart and shook his head, and began to conceive her transformation plan.

Yamato is the largest battleship with the hull actually built in history.

There is a headache about her transformation, which is how to deal with her main gun.

This triple-mounted 460mm cannon is considered a top-notch product among battleships, but it is difficult for the current transformation fleet to play a practical role.

A triple turret including gun barrels and ammunition depot weighs as high as 2,774 tons, which is heavier than most destroyers...

It's useless, and it's big and heavy, but if it's removed, what can I change it to?

The most powerful naval gun here is the Pioneer series naval gun developed and designed based on the 420mm "Pioneer Anti-missile Cannon".

Modern naval guns have a very obvious feature, because of the improvement of technical level, the "caliber" of new naval guns has been significantly improved compared to World War II.

The diameter refers to the ratio of the length of the gun barrel to the caliber. The larger the diameter, the longer the barrel, the higher the initial velocity it can provide, the longer the range, the higher the accuracy and the greater the power.

Of course, the higher the requirements for production technology, the higher the requirements for production technology, after the barrel diameter is increased to a certain level, it will become very unprofitable to continue to improve.

The diameter of the main guns of traditional battleships is basically 45 times, the ancestral 15-inch guns of the British are 45 times, the standard battleships such as the Grand Canyon in the US, the Lexington Battle Cruise, and the South Da North Carolina are 45 times, the illegal Japanese buildings are 45 times, and the French Lisailiu is also 45 times.

The only exceptions are 48 times that of the German Bismarck, 50 times that of the Italian-Eli Veneto, and 50 times that of the American-Eli Iowa.

It can be seen that the reasonable diameter of the naval gun at that time was 45 times the diameter. At that time, it was believed that the diameter of the naval gun would continue to be improved above 45 times the diameter, and the theory was better than continuing to enlarge the diameter.

However, it is obviously effective to continue to amplify. The vertical armor-piercing depth of Veneto's 381mm super-charged cannon is comparable to 406mm, and the effective armor-piercing depth of Iowa's 406mm gun later shells has exceeded that of Yamato's 460mm gun.

These two 50-caliber large-caliber naval guns were also the only large-caliber naval guns in the World War II era, with a depth of more than 800 mm close to the face.

As a post-war product, the Pioneer Cannon was 60 times the diameter from the beginning.

Iowa's 406mm 50-caliber main gun was stuck in the selective data of "effective penetration depth" in the later stage, and finally surpassed the Yamato Cannon.

It is also because Yamato has already gone to sea to raise fish, so there is no possibility of further upgrading, but the maximum armor-piercing depth of the Iowa cannon is still not as good as Yamato.

Due to the design indicators, the Yamato cannon may not explode after reaching the maximum penetration depth, so it is not considered by American testers to be effective penetrating depth...

As for the Pioneer Cannon, there is no need to select data, it can suppress the Yamato Cannon in all aspects.

Even if we do not consider the automatic turret of the Pioneer Cannon, the modern technologies such as the sight tracking radar and the automated fire control system, it also has the same simple and effective weapon that all traditional battleship shells have: tungsten armor-piercing shells.

The specific gravity of tungsten is higher than that of steel. Making armor-piercing shells with tungsten steel can further increase the weight of the shells, thereby improving the shells' ability to retain speed and energy.

With tungsten steel armor-piercing shells, it can use a smaller caliber and lower shell speed, provide a larger range, obtain higher accuracy, and have a greater armor-piercing depth.

For artillery shells, it can be said to be a comprehensive improvement. The super bombs of the American battleships in World War II are the advantages they pursue.

The key is that the tungsten alloy armor-piercing shells can make the shells heavier than superheavy shells, and their technical level is not high.

However, all naval powers have no use, and there is no tradition of using tungsten alloy to build naval shells.

Because tungsten cannot be considered a rich resource on the earth, a country with a large number of tungsten resources in the world that can be used to build shells was not a major industrial country in the era of World War II.

Before the war began, when Germany and Bald, German tanks and air defense guns used tungsten steel bullets. After the war began, the notebooks were smuggled with submarines, but in the end they could not supply them, so they finally replaced them with ordinary steel shells.

The tungsten steel armor-piercing bomb designed for Pioneer Cannon reached 1,700 kilograms with a diameter of 420 mm, and the weight of the bomb alone exceeded the Yamato's 91 Type 200 kilograms.

According to American standards, this has reached the 460mm super-heavy bullet index.

Therefore, Xu Xingchen's 420mm 60-caliber Pioneer Naval Cannon is one level higher than the original Yamato Cannon and Iowa Cannon.

So you have to change the cannon for Yamato, of course you have to change the cannon.

Due to the modern design mechanized loading structure, the turret of the Pioneer Navy gun is much larger than the approximate caliber turrets in the World War II era.

Even a battleship with a 40,000-ton hull can only continue to use dual-equipped turrets.

However, the size of Yamato seems to be able to install the lower triple version.

Xu Xingchen asked the system to confirm that it was feasible after simulation, so he immediately consumed the spoils and assembled a set of triple-mounted turrets to replace Yamato.

The four Lianzhuang 460mm 45-caliber main guns of Yamato were replaced with four triple 420mm 60-caliber main guns.

The maximum range is increased from 42 kilometers to 70 kilometers, the effective range is increased to 50 kilometers, and the rate of fire is increased from 2 to 3 rounds per minute to 6 to 9 rounds per minute.

Although the appearance of the turret and barrel has been reduced, the overall performance has been improved in all aspects.

After changing the cannon, Xu Xingchen deployed 32 sets of four-unit Eagle Strike 12D missile launchers on both sides of her, and a total of 128 anti-ship missiles were installed.

The air defense secondary gun was upgraded during the last renovation, but it basically stopped moving this time, but new air defense missiles were installed.

Two rows of short hanging hairs were stuffed on both sides of the hull. These hanging hairs did not touch the main armor below. Even if they were destroyed, they would not affect the core compartment. They were specially used to deploy air defense missiles.

The power system was replaced again, and four steam turbines were added from eight boilers to nine gas turbines.

It is deployed in three rows, with three units in each row, each with 40,000 horsepower, totaling 360,000 horsepower.

Redesign the hangar, replace the 20 helicopter, add a small dock, deploy a 726 type air cushion landing craft with a load of 60 tons,

Use integrated power system transformation and use specialized hull transformation.

Reintegrate the crew living compartment, merge the residential compartment of ordinary low-level members, and retain the original features while re-arranged with modern living facilities.

Renovate the linear shape of the hull, slightly lengthen the hull, shrink the width of the core compartment, and make the overall linear shape of the hull slightly thinner to adapt to higher speeds.

The Yamato, which was finally transformed, was completely new from the inside out, becoming what Xu Xingchen wanted, and his combat capabilities also had a subversive upgrade.

However, her overall style has not changed. The pagoda-style bridge is still there, the wooden deck is still there, and the hanging hair on both sides is also hidden under the deck.

In addition to the shrinking of the turret, there are dozens of missile launchers around the bridge. At first glance, the overall ship is still the same.

This is the effect Xu Xingchen wants.

There was no large-scale centralized deployment of vertical hair, no bridge was changed to 055, and no four-sided phased array was installed around the bridge, because Xu Xingchen wanted to retain her original style.

After the power of a large number of transformed ship girls gradually showed, Xu Xingchen's fleet combat has long since no longer relied on a specific ship girl.

The ship girls of these super warships in Yamato cannot play much special role. They will be part of the transformation fleet in the future, but the hull is just a little larger.

Instead of completely erasing their characteristics in order to improve the ability of a single ship as much as possible, they become ordinary batch combat ships.

It is better to retain their personality and characteristics as much as possible while empowering them to integrate into the new fleet.
