Liu Changxun did not mean to give Bai Zhizhan a holiday, nor did he say that he wanted to invite him to experience the narrow style, but asked him to accompany Zhao Yu to inspect the Daban Shipyard.

In fact, it also includes shipyards in places such as Lake Kinko.

Although the Imperial State had been defeated, and the imperial authorities had no plans to rebuild the Imperial State, or to use the Imperial State, the shipbuilding industry of the Imperial Kingdom was not backward, and a lot of infrastructure was completely preserved, even if it was not used to build warships, it could be used to repair warships, build civilian transport ships, especially oil tankers that would definitely be needed in the future and were in great demand.

In addition, there are many unfinished warships in several naval shipyards.

This was the main purpose of Zhao Yu's visit to the Imperial State.

The focus is not on the big board, and he came to the big board just to make peace with Bai Zhizhan.

Although Daban was the second largest city in the Imperial Kingdom of Sagi, second only to the Eastern Imperial Capital in terms of population and urban size, and was still the largest port city in Sagi, Daban did not have a decent shipyard, let alone a naval shipyard. Over the past few decades, large slabs have been built only for civilian vessels.

The largest shipyard in the Sagi Imperial Kingdom is actually in Changqi Port.

When the Imperial Navy attacked Chang Wai and the Marines landed outside the port of Chang Wai, the Sagai army destroyed all the infrastructure in the Nagau shipyard and blew up the super battleship under construction, that is, the second ship of the "Sagi" class, leaving not even a complete dock left!

Such a comprehensive and complete destruction has not returned to normal in Changsiao Harbor so far.

As for the former Changwee Shipyard, only ruins remain.

The Nishi-Sagi regime has been trying to get the Changqi shipyard back open, but all the infrastructure has been blown up, and the supporting factories have also been destroyed in the bombing. Even if the Empire is willing to provide appropriate assistance, I am afraid that it will not be until next year, or even the year after, that the relevant assistance will be in place.

It's not that narrow industry has no value, but the strategic situation doesn't allow it.

Until absolute strategic superiority is obtained, the Imperial authorities will never help the Narrow-Empire to develop its industry due to security concerns.

That's right, the first stop that Bai Zhizhan and Zhao Yu are going to is actually Wu Gang.

A few months earlier, shortly after the arrival of the National Guard, the National Guard of the Sagai had captured the port city in the western part of the island.

The key is that the Eastern Sayi army guarding Kure Harbor did not have time to sabotage before it was routed.

As a result, the super-battleship "Saji" under construction, as well as the main infrastructure of the Kure Port Shipyard, were preserved.

It's just that the fighting around the area, which lasted until the second half of the year, did not end.

By the time the Sagi National Self-Defense Force had occupied Kure Harbor and begun to advance eastward, the Imperial Navy had almost forgotten about the unfinished Sagi warships in Kure Harbor.

It was not until the defeat and surrender of the Sayi Imperial State that the officials of the Imperial Navy in charge of counting the spoils of war found that there was still a ship in Kure Harbor that had been fully completed, and the superstructure had been completed for more than half of the time, and even the main gun turret had been installed, but it had not yet had time to install the super battleship with the main gun.

In fact, the supporting 460-mm naval guns were also stored in Kure Harbor, but they were not loaded on the "Sagi".

In the Kure Harbor naval warehouse, there were even dozens of 460-mm shells that were produced and planned to be tested after the delivery of the "Sagai".

After sending people to investigate, the Imperial Navy learned that the completion of this battleship had reached 75%.

Through the field trip, a lot of doubts were also solved.

For example, it is equipped with a 460-mm main gun, which is not the previously claimed 16-inch main gun; The standard displacement is definitely more than 60,000 tons, and the full load displacement may reach 70,000 tons, which is 20% higher than previously claimed; There are only 12 boilers with a maximum pressure of only 3.8 megapascals, the power system output is about 150,000 horsepower, and the calculated maximum speed is 27 knots, which does not reach the minimum threshold of a fast battleship.

In addition, the hardness of the armor steel used in the ship did not reach the standards of the Imperial Navy!

According to calculations, the ship's main armor belt is up to 410 mm thick, and its equivalent protection thickness is equivalent to between 330 and 350 mm of armor steel used in the Imperial Navy.

In other words, the ship's protection capability is slightly better than that of the "Asahimi" class, which has a thickness of 320 mm in the main armor belt.

Because in order to obtain high speed, the "Xuhai" class did not require protection to meet the standard of battleships, that is, to resist heavy armor-piercing shells fired by its own main guns, so theoretically, the "Narrow" with comparable protection performance could not block the 400-mm heavy armor-piercing shells of the Imperial Navy within the effective combat range.

At least according to paper data, the "Sashiyi", which is more than 60,000 tons, is not much stronger than the "Xuhai" class, which is more than 20,000 tons lighter.

If the speed is taken into account, in a one-on-one battle, the "Saji" may not be able to defeat the "Asahimi".

If anything, it's just that the ability to resist blows is definitely much stronger.

Relying on thick armor and a huge hull, the "Saoyi" can withstand blows, especially the ability to resist torpedoes, definitely surpassing the "Asahimi" class.

It is difficult to give a definite answer from theoretical calculations as to how much it exceeds.

In fact, Zhao Yu came to the Imperial Kingdom to find out the actual performance of the "Narrow", that is, how powerful this behemoth is.

As for figuring out the reasons, it's more realistic.

Before, didn't He Yongxing always make efforts to build the "South Zhuhai"-class fast battleship?

In the design stage of this kind of fast battleship, it was actually aimed at the "Narrow" of the Narrow Navy, as well as the legendary "Yihua" class of the Newland Navy. Because of the previous information, the design displacement of the "South Zhuhai" class was only 50,000 tons, which is close to 50,000 tons to be exact.

In fact, before the outbreak of the Great War, the Sixth Bureau updated the relevant data of the "Narrow" and also re-evaluated the "Yihua" class battleships of the Nuland.

The last assessment report greatly increased the displacement of the "Narrow Yi" class, and also made a relatively accurate judgment on the caliber of the main gun. That is, after determining that the "Sagi" had only 9 main guns, intelligence analysts concluded that it was not equipped with 16-inch main guns. It was only at the beginning that it was judged that the Sagai Navy was on par with the Imperial Navy, and the "Saga" was equipped with a new naval gun with a caliber of 450 mm.

In addition, the Sixth Bureau identified the "Yihua" class as a post-treaty fast battleship with a speed of more than 30 knots and a standard displacement of about 50,000 tons.

It was only on the basis of this information that the Imperial Navy determined the design indicators of the "South Zhuhai" class.

In this version of the design, which is about to be completed, the "South Zhuhai" class will use nine 450-mm guns, with a standard displacement of not less than 50,000 tons and a speed of at least 32 knots.

Such a high index makes the cost of "South Zhuhai" level extremely high!

If it can be proved that the more than 60,000-ton "Narrow" cannot withstand bombing and shelling, it will also prove that there is no need to build the "South Zhuhai" class.

In Zhao Yu's words, the construction of 1 "South Zhuhai" is enough to purchase 3 "provincial" ships.

If the "South Zhuhai" class can be dismounted, the saved resources will be able to start the third batch of "provincial" class, and at least 8 ships can be built.

There are 8 more large aircraft carriers, what's wrong?

Liu Changxun also attached great importance to this matter, so he asked Zhao Yu to come to narrow the imperial kingdom, and also called Bai Zhizhan to let the 41st task force go to cry in advance.

A few days ago, the "Sagi" was towed to the test area west of Changwee.

The live-fire test is being conducted in the next few days!
