While Mu Feng helped IJN immigrants build infrastructure, he did not let them go freely.

They are immigrants who have been taken over by themselves, and they have provided the land and all the means of production by themselves, and of course they will not let go directly, and they must grasp everything they can in their hands.

When they arrived, Mo Yu arranged for a group of free ship girls to go over, and these ship girls were "instructors", and each fleet of 36 people arranged at least one "instructor".

The instructor has the same status as the opposing fleet commander, and the task is to guide them on how to better work, study, and live here, and the hidden task is to educate and transform their minds.

When you encounter a major change in your life and enter a new region and society, it is the easiest time to abandon your old way of life and embrace new cultures and habits.

After the long-term guidance and indoctrination of the instructors, the gap between the lifestyle of these original Japanese ship wives and their relatives in their hometown will become wider and wider.

As for the IJN headquarters, Yoko Yamato has never been seen, and several aircraft carrier veterans such as Akagi have almost given up looking for them now.

Now they are all concentrating on consolidating their power and organizing the second batch of immigrants.

Yamato finally made a decision to arrange one person from each of his family's three families to join the second batch of immigrants.

After a short period of thought, Akagi did not refuse Yamato in the end.

In the next few days.

Ninghai and Pinghai are in Tingfeng Island, following the two admirals of Xuelang Bay and Tingfeng Island, as well as Chen Ping of the Anping Admiral's Mansion, to study together as auditors.

Admiral Jiangnan watched the whole process from the rear through the vision of Pinghai and Ninghai, and gradually gained an in-depth understanding of the unique way of thinking and handling things of this overseas fleet.

The way of thinking of these people and the ship's mother has slowly changed.

The Nanchang Fleet went all out to carry out internal integration and transformation, and did not launch a battle against other Admiralty.

However, it completely took over the defense of the western entrance to the bay, and every time a deep sea wandered in, it was crushed and eliminated with absolute superiority, and there was no need for other admirals to be involved.

In fact, almost half of the deep sea that comes every time it hits will be taken back or taken prisoner, sent back to Newport by plane, and handed over to Crimson for transformation.

The other Admiral's Mansions and the Imperial Court further relaxed their vigilance, and couldn't help but begin to hope that the Nanchang Fleet would be content if they occupied the two Admiral's Mansions.

Their fleet is strong, and they also helped to resist the attack of the deep sea, and in the future, the interior of the bay is really peaceful.

Based on this thinking, on the issue of the organization of the encirclement and suppression fleet, all parties have gradually entered into a more long-term quarrel, and no one wants to have more people.

Admiral Izumo and Izumo also slowly relaxed their vigilance and prepared their plans with all their might.

Mu Feng has been active in the scientific research center, manufacturing center, and transformation center in the past few days.

Prepare a second fleet of detergents, specially prepared some equipment for transformation and upgrading.

First of all, Mu Feng wanted to design a larger caliber battleship main gun.

In fact, the power of the Crimson 380 main gun is sufficient, and the reduced version of the universal version is very good, and a 20,000-ton battleship can fit two triple turrets.

Now Mu Feng designed the new large-caliber main gun for two purposes.

The first is to increase deterrence, before the real war, for traditional commanders and ship mothers, the larger the caliber of the main gun, the greater the deterrent.

Although its 380 is more powerful than the average 406, it seems to be less deterrent.

For example, there is no obvious difference between the size of a 100,000-ton nuclear-powered aircraft carrier and an 80,000-ton conventional-powered aircraft carrier, and there will be no essential difference in actual combat effectiveness.

But for the deterrence of the people who eat melons, it is not a level at all.

The second is to use it as an upgrade reward, the battleship girls of the headquarters, change to a large-caliber main gun, whether there is a substantial improvement or not, they will always be happy for a while.

So Mu Feng decided to design a modern battleship main gun with a larger caliber that is actually useless in modern times.

The barrel and turret design, basically copied the Crimson 380, the key was to increase the caliber.

The 380 mm is the 15-inch class, and the next step up is the 406 mm in the 16-inch class.

The independent design of the metric country, of course, will not be limited to the strange caliber converted from the imperial standard, and Mu Feng decided to put it together.

Just like 15 inches is equal to 381 mm, but Germany and France, as metric countries, designed the main guns of the same level, and they all coincidentally cut 1 mm and took 380 mm.

It should be noted that although the Veneto-class main gun is 381 mm, it is not a British country, and the unit he uses is millimeters, not inches.

I didn't round up like France and Germany, maybe I didn't think I could afford to suffer.

The main purpose of Mu Feng's design of the new main gun is deterrence, of course, it cannot be reduced to a small size.

406 mm rounded up, then it becomes 410, and the 410 used in history has already had a Nagato class.

Modern main guns, because of the progress of the production process, the barrel will be thinner, and the same caliber, the new one will look slightly thinner.

Mu Feng groaned slightly, and finally set the caliber of the new main gun at 420 mm, the reason is very simple, it is guaranteed to be larger than the 406 at a glance.

As for how much it is converted into inches, Mu Feng didn't bother to care.

There are two types of turret designs, the standard row of more than 35,000 tons is equipped with triple, and the lower 35,000 tons is equipped with double.

Mu Feng consumes artillery equipment, directly completes scientific research tasks, and puts the drawings in the manufacturing center for production.

After the new main gun was completed, Mu Feng began to design a new aircraft.

Qingyu's hangar is very large, equipped with a modified version of the Panda, which can hold up to 120 aircraft.

However, in the actual combat of these two days, it was found that when there were more than 100 aircraft operating at the same time, Qing Yu began to be unable to take care of it, and the efficiency of deck scheduling was significantly reduced.

Mu Feng found that there seems to be a limit to the number of aircraft that an aircraft carrier can operate, and this limit is likely to be around 100.

Aoha's hangar and deck are large enough that if they are not full then they will be wasted.

So Mufeng decided to design a larger and more powerful propeller aircraft.

The original intention of designing this kind of aircraft was to fill the hangar for Qing Yu, but the ultimate goal was not just to help her fill the hangar.

The propeller aircraft has low power consumption, fast start, simple operation and maintenance, convenient take-off and landing, low requirements for airports, gravel roads, and even grass can fly.

Because of these characteristics, even in the jet age, propeller aircraft have not been completely eliminated, and there is still a wide demand in modern society.

Mufeng intends to take this opportunity to design a modern propeller aircraft.

First, it is used to upgrade aircraft carriers that have not changed their beveled decks for the time being.

The second is to give it to the human government in the later stage for low-intensity battles such as patrols, reconnaissance, and ground suppression.

The third is to serve as an internal rapid transportation tool for places such as Tingfeng Island and Xuelang Bay.

Fourth, specific improvements can be designed in the future, which can be used to extinguish fires, spread pesticides, fly teaching, air shows, and so on.
