In fact, there is another test that has not been conducted.

Test the armor protection of the Imperial Navy battleship with the 460mm cannon of the Navy.

Of course, it is definitely not for the battleship to be beaten, but instead of the battleship with armored steel plates of the same quality, and only armor protection is tested.

To put it bluntly, it is to test the ballistic performance of the 460mm naval gun at all ranges.

Initially, the Navy planned to use the assembled 460mm naval gun on the "Sayi" to test it, and even installed thousands of tons of armored steel plates on a landing ship, preparing to send these steel plates to a small island outside Changqi Port and then assemble them into targets for testing.

If so, the "Sayi" can survive ten days and half a month longer.

Later, when searching Wugang, the Imperial Navy discovered a 460mm naval gun that had not had time to install and several brand new gun barrels.

The key is that the design drawings of the 460mm shell were also obtained.

Now, there is no need to use the "Sayi" to test it.

Later, the test was arranged on the empire's land, to be precise, on an island in the northern part of the Turbid Sea, using a shore defense turret that had been abandoned for decades.

Although the Imperial Navy announced the test results to the public on the 20th anniversary of the end of the war, it is no secret that it really means.

If this 45-diameter 460mm naval gun is used to use a standard armor-piercing bomb with a weight of 1315 kg, the armor-piercing performance is only comparable to the 400mm heavy bomb of the Imperial Navy, or it is slightly better, and there is a clear gap between it and the 400mm super-piercing bomb.

The key is that the elastic weight coefficient is too low.

Due to the limitations of metallurgy, forging and finishing, the 460mm naval gun barrel pressure is much lower than the Imperial Navy's L55 400mm naval gun. Even if it is a full-charge armor-piercing bomb, its initial velocity is relatively low. Therefore, when fighting at long distances, the external ballistic performance is very poor.

If the range exceeds 20 kilometers, there is no accuracy at all!

In addition, the full charge life of the 460mm gun barrel is less than 100 rounds!

Whether it is the performance of the 460mm naval gun or the fragile armor of the "Sayi", it is all the backward industrial technology of the Sayi Empire, so it has to expand the caliber of the main gun and increase the thickness of the armor to ensure that it competes with the opponent's new battleships.

For the narrow-minded imperial country with weak industry, this is equivalent to digging a grave.

To put it another way, if two "Sayi"-class resources are used to build aircraft carriers, the Sayi Navy can add at least two fleet aircraft carriers when the war begins. If the Sayi Empire delays the war start for one year, it is even possible to have four additional fleet aircraft carriers. If the war is not defeated within a few months after the war begins, the resources for building two super battleships can be used to build eight fleet aircraft carriers.

Even if you only add 2 fleet aircraft carriers, the battle situation will be very different!

If there are 4 more aircraft carriers, the Navy will even have a chance to defeat the Imperial Navy!

Unfortunately, the Nai Navy led by Takano chose the battleship destined to be eliminated.

However, these are all off-topic words.

Bai Zhizhan and Zhao Yu returned to the imperial capital on the night of the 15th, and went to the official residence of the chief minister overnight. Zhao Yu introduced the naval shipbuilding plan to Xue Yuanzheng.

Zhao Yu focused on the "South Zhuhai" class rapid battleship, hoping that Xue Yuanzheng could come forward and cancel or postpone the construction plan of such battleships.

In order to enable the construction of small aircraft carriers to be started in time, Zhao Yu submitted a "South Zhuhai"-level design book before going to the Sayi Empire in early November.

Because according to the wartime construction plan, the first allocation for the start of construction was issued in June, Liu Changxun had no right to order the cancellation of construction work.

Only Xue Yuanzheng has this power.

Xue Yuanzheng did not agree immediately, but said that he would seriously consider the suggestions put forward by Zhao Yu, and asked Zhao Yu to quickly improve the next generation of main warships after returning, mainly the design of large aircraft carriers to ensure that construction can be started immediately after the second batch of "provincial"-level construction is completed.

According to Xue Yuanzheng's meaning, there are only two batches at the "provincial" level.

It’s not that this large aircraft carrier is not good enough, after all, it has not been officially put into service, and the Navy’s feedback during the construction process is pretty good.

Mainly not big enough!

Because survival performance is put first, the number of carrier-mounted aircraft at the "provincial" level does not meet the standard, that is, after two full-deck attacks are launched in a row, there will be no carrier-based aircraft available. According to normal standards, after the aircraft carrier, as the absolute main force, must retain air defense fighter jets, at least one squadron, and it is best to reach two squadrons.

It should be said that the number of more than 90 carriers at the "provincial" level is barely enough to launch two full-deck attacks in a row.

According to this standard, the capacity of the aircraft must be increased by at least 10 aircraft, preferably 20 aircraft.

The most direct way is to expand the size and increase the displacement.

Anyway, for an aircraft carrier worth tens of thousands of tons, even if the power system is not modified and the increase is thousands of tons, the speed will drop by 0.5 knots.

According to the navy, it is best to redesign.

Zhao Yu has been dragging on this matter, not just being lazy, but wanting to wait for the first batch of "provincial" to withstand the test of war and obtain feedback from the navy.

In fact, this is common sense in designing warships.

The "provincial" level is definitely not flawless, but what are the problems and how serious are they, you will only know after use.

In addition, the Navy's feedback is also very important.

It is precisely because Zhao Yucai advocated the construction of the third batch of "provincial"-level, postponing the start of the next large aircraft carrier by about a year.

In Zhao Yu's words, in the next three years, we will not encounter an aircraft carrier that is more powerful than the "provincial" level on the battlefield.

The implication is that the "provincial" level is good enough to defeat all opponents you encounter in the next three years, and there is no problem of lagging behind or being beaten.

However, Xue Yuanzheng's attitude also gave Zhao Yu a reassurance.

Obviously, the construction of large aircraft carriers will definitely not stop.

Zhao Yu was also very tactful. After finishing the report and receiving Xue Yuanzheng's instructions, he took the initiative to say goodbye and leave without staying to wait for the battle in vain.

"What do you think about this?"

"Old Zhao is a wooden man. I used to say that he had water in his head and likes to be serious the most, so..."

"It's not him, and what he said is a bit one-sided." Xue Yuanzheng breathed a sigh of relief and said, "Although I am not a naval general and don't know much about the navy, as far as I know, battleships still have value. For example, the "Yuejiang" played the role of a stabilizing sea needle on the island of Serbia. What's more, there is already information that the Newland Navy is building three types of fast battleships at the same time."

"The 'Yihua' level has started construction?"

Xue Yuanzheng nodded and said, "The first two ships sent by the Sixth Bureau a few days ago have already started construction, and the other two have also received funding, and will start construction in January next year. With the same information from the Sixth Bureau, this kind of post-treaty-type rapid battleship will definitely surpass our treaty-type rapid battleship."

Bai Zhizhan had already frowned, this was not good news.

"Just discuss these naval affairs with Liu Changxun."

Bai Zhizhan nodded. He had already thought that it was Liu Changxun's proposal to build the "Southern Zhuhai" level that Xue Yuanzheng did not adopt Zhao Yu's proposal.

Zhao Yu is just the chief technical consultant of the Navy, and his voice is definitely not as good as the commander-in-chief of the Shanghai Army.
