This Dunz is also kind, or rather a sense of honor.

After a few tentative idle words, seeing that Bai Zhizhan didn't talk, he didn't talk about it anymore, and returned to the topic of friends' feelings.

This is also the reason why Bai Zhizhan is willing to associate with Dunz.

If it is said that attaching importance to honor is a common characteristic of all military personnel in the world, then a strong sense of rules is certainly a major characteristic of military personnel.

In layman's terms, no matter what you do, you will take the initiative to break the rules.

On the battlefield, the strictly disciplined Rangman soldiers have amazing combat effectiveness, and the legion composed of tens of millions of Rangman soldiers is an invincible war machine.

It's just that in life, it's not necessarily a good thing.

In Gui Boyong's words, his face is relatively thin, and he can't pull it off many times, and no matter what he does, he looks very stereotypical.

Good for working together, not for drinking together.

It didn't take long for the hall to be packed.

The negotiators of the Empire had only arrived today, and they had not yet settled down, so everyone had lunch in the main courtyard cafeteria.

When he went to pick up the food, Bai Zhizhan met Wang Kaiyuan.

After being introduced by Bai Zhizhan and getting to know Wang Kaiyuan, Deng Zi said goodbye and left.

"You know him well?"

"Sort of."

"Then you'll have to hurry."

"Hurry up and do what?" Bai Zhizhan didn't understand what Wang Kaiyuan meant.

"He is now the chief of staff of the submarine force of the Manman Navy, and he will soon be able to rise to the ranks." Wang Kaiyuan said, walked over and closed the door. "In this negotiation, if there is anything that the Imperial Navy wants, it is the ocean-going submarines of the Manman Navy, especially the technology for building ocean-going submarines."

Bai Zhizhan frowned, Wang Kaiyuan's words were not nonsense, it was true.

Compared with the Liang Xia Navy, the Manman Navy is not worth mentioning at all in other aspects, not to mention that there is no aircraft carrier so far, even if it is a traditional capital ship, it is a sword sharpened in ten years.

The only thing that can take the table and surpass the Liangxia Navy is the submarine.

The Liang Xia Navy has always attached little importance to submarines, and has not even regarded submarines as major combat ships, let alone in-depth research.

Submarines are really useless?

Apparently not!

Submarines have been of great value in all the war plans developed by the Imperial Navy over the past decade or so, but only in the late stages of the war.

At the beginning of the war, there were really not many places for submarines.

Even the strategic blockade of the Imperial State was dominated by ocean-going ships such as light cruisers and destroyers.

The most crucial reason for restricting submarines in the early stages of the war was to avoid providing a casus belli to the Nuland Federation and other powers.

Unrestricted submarine warfare is an act of war expressly prohibited by the international laws of war.

The Liangxia Empire, one of the founding signatories to the international laws of war, was adamantly opposed to unrestricted submarine warfare even during the last war.

If the combat actions of submarines are restricted, it is better to build light cruisers.

Submarines, which were originally torpedo boats capable of diving, relied entirely on sneak attacks and lost the ability to sneak attack, and they were inferior to destroyers in tonnage.

It was not until the latter part of the war, when the Newland Federation and the Kingdom of Bran entered the war, that there was a need to vigorously develop submarines.

In Zhu Shijian's words: If it is necessary to launch unlimited submarine warfare against the Narrow Imperial State, this battle should not be fought, and it is better to compromise as soon as possible.

The submarine forces of the Imperial Navy have always been developing in accordance with the "long-term goal".

The main thing is to train talents, and the construction of submarines is not in a hurry.

Almost all of the dozens of small submarines that can only operate in coastal waters are training boats, and their value is to train submarine officers and men.

According to the original plan, the large-scale construction of ocean-going submarines will be 100 years after the new calendar.

It's just that for now, I'm afraid I have to start early.

If the Nuland Federation is going to enter the war this year, or even in the second half of the year, the Imperial Navy will have to consider immediately expanding the size of the ocean-going submarine fleet.

At the very least, the pace of construction should be accelerated immediately.

Obviously, this is the problem.

Not that there is a lack of industrial strength to build submarines, but that there is no suitable design!

To build submarines, small shipyards are sufficient, and there are ten shipyards in the lower reaches of the Nanjiang River and the northern coastal areas of the empire.

However, until the outbreak of the Great War, the Imperial Navy did not have a suitable design plan for ocean-going submarines.

The twenty ocean-going submarines were all emergency products improved after the end of the last war, with the last large submarine built during the war.

To put it mildly, it is used to fill the gap in the total tonnage of submarines stipulated in the treaty.

Obviously, it has long been outdated.

The reason for this situation is, fundamentally, the Imperial Navy itself.

Over the past decade or so, almost all capable designers have been poached by projects such as fleet aircraft carriers and fast battleships.

There are not enough cutting-edge talents such as ship designers in any country.

Besides, designing a submarine is not so easy.

In terms of sophistication, submarines surpass any kind of surface warship.

Theoretically, all surface warships are open architectures, and only need to increase the size and displacement to achieve the design indicators.

Submarines are just the opposite.

Because it is a closed structure, all the basic parameters, dimensions and displacement cannot be changed at will once they are set. What the designer has to do is to achieve all, at least the main design indicators, in strict accordance with the limited tonnage in this limited space.

This feature determines that it is difficult for the designers of surface warships to switch to designing submarines.

Zhao Yu tried, but finally gave up halfway.

It was only after hitting a wall that Zhao Yu proposed to the Navy Command to fund a shipbuilding consortium integrating design and construction in Wuzhou and Changzhou in the lower reaches of the Nanjiang River, competing with other large shipyards in a dislocation position, mainly engaged in the design and construction of submarines and other special ships.

The result of this proposal is the current Wuzhou Shipyard and Changzhou Shipyard.

Unfortunately, the integration of the two shipyards was completed only at the beginning of the new calendar 99.

In addition, the problem of lack of designers has not been solved.

Before the outbreak of the war, Wuzhou Shipyard and Changzhou Shipyard each submitted several submarine design documents, all of which were sent back by Zhao Yu.

Because the designers seriously lack experience in designing ocean-going submarines, these schemes are all amplified on existing small submarines.

When enlarged in equal proportions, it is an ocean-going submarine?

It's as simple as that, where you need a designer, it's enough to find a few tape measure workers.

According to Wang Kaiyuan, one of the goals of the negotiations is to strive for the introduction of ocean-going submarine design plans from the Empire in the form of technology exchange.

There is a ready-made plan, which can first let the shipyard practice and train the workers.

By improving the introduced schemes, submarine designers will have the opportunity to exercise and gain a new understanding of advanced ocean-going submarines.

Wait until everything is ripe, and then design a new ocean-going submarine from scratch.

If it goes well, it will actually take a year or two.

These things do not need to be kept secret, they will be informed to the negotiators of the Empire as soon as the negotiations begin, and it is not a secret that the Liangxia Navy lacks ocean-going submarines.

When it comes to business, Bai Zhizhan is interested.

After lunch, he followed Wang Kaiyuan back to the East Courtyard.

In Wang Kaiyuan's words, he slept all the way, and there were still many classes that needed to be made up, so it was best to go outside to surf less.
