For battleships, even for the same tonnage, it becomes quite difficult to upgrade here, and the synchronization rate increases very slowly.

Only a very small number of ships can increase the synchronization rate to 60 and then unfold the hull.

Even in the new battleship families such as Veneto, Richelieu, Iowa, and Yamato, only a few individuals in each family can do it, and most of them can only settle for the next best thing and use the 058A ship, which is much easier to operate.

And what makes Mu Feng feel strange is that there are 4 avant-garde families, 3 Missouri families, and only 2 Yamato families.

Except for a slight gap in the level of science and technology, Mu Feng can only think that it is because Yamato's family is too small, and there are only 6 people.

As for the relatively old battleships, only one or two people in the family could carry them.

As for the upgraded version of 059A, the number of people who can control it has been cut in half again, and even the most cutting-edge battleships can only be operated by one or two people in a family.

In the era of Nelson, Colorado, and Nagato, only parents can drive it.

In the earlier battleships, except for the war-weary and the head of a special family like Hood, the others were basically wiped out.

In the end, in the entire alliance, among the ship girls from various headquarters, there are only more than forty ship girls who can use 059a, the ultimate ship equipment.

Among the deep-sea transformation ships, there are 16 deep-sea first-class battleships such as Snow Feather, 64 second-class battleships such as Condensation, 32 third-class battleships such as Crimson, and 16 fourth-class battleships such as Binghe, a total of 128 deep-sea transformation ships have been upgraded to 059A.

The higher the level of the deep sea, the higher the success rate of leveling up, but the higher the level, the lower the number of deep oceans.

The lower the level of the deep sea, the larger the number, but the success of leveling up is very low.

So the end result is a spindle-shaped data with a large middle and a small end.

As for the total number is more than the ship's mother, it is because the overall number of the deep sea is too large.

Of the 2 million ship mothers now, only about 500,000 are native ship mothers, and only one-third of the deep-sea transformation ship mothers, so the final number is almost three times that of ship mothers.

As for Mu Feng's modern Chinese ship mother, and the new ship girl born through research and development later, the upgrade ratio is completely different from both of them.

For the twelve 059s such as Taiwei, Shaowei, Lingtai, and Emperor's Throne, upgrading the ship's equipment to a larger 059A is only a fairly small increase, so all of them were easily upgraded successfully, and the synchronization rate was not reduced much.

For Qinglong, Xuanyuan, Teng Snake, Tianmen and other 058, it is equivalent to the previous 052c upgrade to 055, the difficulty is not great, and all 32 people have been successfully upgraded, but the synchronization rate is high and a little low, but they can be quickly improved through exercise.

Then most of the 055 in Nanchang and Lhasa, some 057 in Yunzhong, Qiancheng, Changping, Daxia, etc., a small number of 052c and 052d in Changchun, Taiyuan, Lanzhou, Kunming, etc., as well as a few other earlier guides in Hangzhou, Shenzhen, Qingdao, Guangzhou, etc., have been successful.

There are only a few hundred modern ship girls in total, and the total number of people who have completed the upgrade is almost a hundred.

And almost two million ships and the transformation of the deep sea, there are only more than a hundred people, this proportion is not an order of magnitude at all.

The reason for such a big gap is actually simple, one is that Mu Feng's modern ship mother has a small technical span, the second is that their system fit is high, and the third is that Mu Feng's ship mother will not repeat, so there is only one person in the family, which means that everyone is a parent.

If you compare all the battleship families of World War II ships separately, the gap between the two sides will be narrowed to single digits.

Like 059a, the upgrades of Mufeng's other modern ships are actually quite large.

Some of the missile boats have been upgraded to 057A, most of them are 054A, most of the frigates have gone to 058A, a small number of 055B and 055A, and some of the 057 have even been upgraded to 059.

Most of the modern missile destroyers have reached 059, and a few have stopped at 058a.

The landing ships, amphibious ships, and aircraft carriers on the other side, Mu Feng has also prepared similar upgrade routes.

The family of landing ships and amphibious ships has 072B with 10000 tons, 071B with 20000 tons, 071C with 30000 tons, 075A with 40000 tons, and 075B with 66000 tons.

The aircraft carrier series includes the 20,000-ton 707, the 30,000-ton 707A, the 40,000-ton 891, the 50,000-ton 891A, the 60,000-ton 002A, the 80,000-ton 003A, and the 130,000-ton 004A.

These are all commonly used drains, and a full discharge needs to be added.

Simply looking at the arrangement of these hull tonnage data, the excess between each other is relatively smooth, and the proportion of each increase is not too large.

However, the size of the hulls of the landing ships, amphibious ships, and aircraft carriers of the headquarters is significantly smaller than that of the battleships.

The landing ships and amphibious ships of the headquarters are all converted from escort aircraft carriers and light aircraft carriers

The hull tonnage of escort aircraft carriers may only be a few thousand tons, and most of the larger light aircraft carriers are only in their early 10,000s, and only a few can reach more than 20,000 tons.

The standard displacement of fleet aircraft carriers, most of which are only a little more than 20,000 tons, has tripled all of a sudden when upgraded to 003, and nearly fivefold when upgraded to 004.

The tonnage gap between the hull and the target ship at the beginning of the Yuan Dynasty was too large, and the upgrade rate was much higher than that of the missile ships.

And the number base of aircraft carriers is already lower than that of missile carriers.

Coupled with the soaring technical complexity, for the aircraft carrier Niang of World War II, when upgrading to the 60,000-ton 002A, the difficulty is already comparable to the battleship upgrading to 059A.

Purely looking at the difficulty and quantity ratio, the aircraft carrier mother may all stop with 002a.

However, due to the willpower and control ability of the aircraft carrier girls, they are very strong.

In the end, there were almost 20 of all the World War II aircraft carrier mothers who were upgraded to 004A-class aircraft carriers.

These ships are either Enterprise, Forrestal-class Saratoga, Midway, and other very few high-level aircraft carriers.

Either Lexington, Essex, Guanghui, Dafeng, Zeppelin and other families, heads of families, patriarchs.

At least it is also the first ship mother directly created by stars such as Victory, Lexington Essex, and Richelieu.

Among these few aircraft carriers, there is one of the most special, and that is Richelieu.

Richelieu was converted from a battleship to a modern aircraft carrier, but he did not encounter too many problems in the process of upgrading, and he succeeded all the way through his efforts.

Mu Feng felt that Richelieu might have been an aircraft carrier in the first place, so there was such a result.

Because the overall difficulty of the upgrade is very high, even if it is the second-level 003 change, the number of aircraft carriers that have been successfully upgraded has not exploded on a large scale, and there are only more than 40 people in total.

The upgrade status of the deep-sea transformation ship is also relatively ugly.

There are 16 deep-sea first-class aircraft carriers including Xingyue and Qingyu, 16 deep-sea second-class aircraft carriers including Xuehai, and 8 deep-sea third-class aircraft carriers, and a total of only 40 deep-sea transformation aircraft carriers, which have been upgraded to 004.

upgraded to 003, less than a hundred.

Finally, there is the modern Chinese aircraft carrier Niang.

Liaoning, Shandong, Guangdong, Fujian, Jiangsu, Zhejiang, and other six 003 and previous aircraft carriers, Ziwei, Huagai, Wenchang, Gouchen, Xuange, Beidou and other twelve native 004, all have been successfully upgraded.

The problem is that the total number is too small, only 18 in total.

Although the number of aircraft carriers upgraded to the highest level can be said to be pitiful compared to the huge number of ships, Mu Feng is already quite satisfied.

With 80 160,000-ton supercarriers and more than 160,000 80,000-ton large aircraft carriers, this fleet is already a force majeure on the earth.

The last to start the activity are auxiliary ships, which have not stopped upgrading compared to the constantly upgrading combat fleet.

Yuanwang series space survey ships, 815A series electronic reconnaissance ships (Neptune), 901A series ocean-going supply ships (Hulun Lake), 920A series hospital ships (Peace Ark) and other types of auxiliary ships have also developed a new generation of ship equipment, and formed different numbers of native ships.

The original auxiliary ships have all been upgraded, and the energy system has been completely renewed.

In fact, because we know that the space age is coming, the design of these latest ship equipment takes into account the environmental needs of space, and the ship equipment and hull can be deployed normally even in the space environment.

The ship girl is not a human in the first place, and her physical strength is completely different, even if she is directly exposed to outer space, there will be no danger.

Now, as long as the space engine is installed and the specific cabins and equipment are sealed, it can be used in a small range of activities in the space environment.

Moreover, now that there is an aerospace plane, the ship's mother takes the plane into space, and when she unfolds the hull in space, it becomes a space battleship.

Of course, this is only an excessive state, and in the future, it will be necessary to specially design the ship's equipment to adapt to the space environment, and then gradually replace it for everyone.

Mu Feng understood the situation of the alliance as a whole, let out a long breath, turned off the system, went to the nearest scientific research center, and began to plan for future work.

Now everyone's first job is to tackle key problems in scientific research.

After entering the Earth's universe, scientific research work was divided into two general directions.

One direction is to cooperate with the stars to restore the function of the final fortress, and the ultimate goal is to restart the original universe.

This is a long project spanning hundreds of thousands of years, and the technologies involved are the most cutting-edge, the most core, the most basic and the key.

Including space-time coordinates, super-space-time navigation, space compression, mass-energy transformation, cross-universe positioning and transfer, etc.

In this direction, a large number of basic technologies will be born, while the other direction will mainly be the expansion of applied technologies.

It is necessary to design and build a space base, design space warships and corresponding weapons, and transform the ship's equipment and hull.

Assemble a space exploration fleet and shift the scope of civilization from land and sea to sky and stars.

The road ahead may be difficult or long, but I will not hesitate if I have a goal.

After all, I and everyone in this world have already experienced the rise and fall of a universe, and now nothing can stop it.
