However, to the Japanese Navy, it is a little regrettable that due to the limitations of large cranes (the warships that can be built with the modular shipbuilding method are only 10,000 tons), the modular shipbuilding method can only be used to build ships with smaller tonnage for the time being, the largest of which are destroyers and submarines, so although the construction speed of large and medium-sized warships, including aircraft carriers, is much faster than in history, it is still impossible to compare with light ships such as Akizuki-class destroyers, and the construction speed is only 30%-100% faster than the original. Well, that's pretty impressive

Although the overall strength of Japan's shipbuilding industry cannot be compared with that of the United States and Britain, due to the outstanding contribution of the Federation of Industry and Economic Affairs, by the end of 1941, the production and management level of Japanese industrial enterprises, especially the most basic shipbuilding industry, was not inferior to that of the United States. Hu Weidong brought a considerable part of his management experience beyond the times, so it is certainly in line with the Japanese national character (Note 1), and it is reasonable that the Japanese can quickly master these new management methods.

There is little difference in production efficiency (because the hardware level is still inferior to the United States and Britain, so it is still slightly inferior in general, but after all, it is much stronger than in history.) The gap in the industrial base was also narrowed by the aid of the United States over a period of time, and by the end of 1941. Although the United States' ultimate shipbuilding capacity is still more than 3 times that of Japan, compared with the 10-fold gap in history (only in terms of ship production, it should not reach a 10-fold gap, but in history, the United States has also built a large number of merchant ships, and some of this production capacity can be used to build ships, not to mention that the United States has not carried out a general mobilization), after all, it is still much smaller.

And under this premise, the output of several types of ships built by the Japanese with all their strength is quite amazing. Taking aircraft carriers as an example, they suffered frequent setbacks during the war of aggression against China. At one point, the Japanese Navy had only four aircraft carriers under repair. But in August 1939, the heavy aircraft carrier Shozuru was completed and commissioned, bringing the strength of the Japanese naval aviation back beyond its pre-war level, and this was only the beginning.

November 1939. The heavy aircraft carrier Zuihe was completed and put into service; February 1940. The heavy aircraft carrier Dafeng was completed and put into service; November 1940. The medium-sized aircraft carrier Yunlong was completed and put into service; In January 1941, the medium-sized aircraft carrier Amagi was completed and put into service; In February 1941, the medium-sized aircraft carrier Katsuragi was completed and put into service. At this point, the total number of aircraft carriers in the fleet owned by the Japanese Navy reached an unprecedented 10. And the aircraft carriers of the Japanese Navy are not only in quantity, but also in much better quality than the Japanese aircraft carriers in history.

On the one hand, this is because Japan's industrial base is much stronger than in history due to the aid of the United States and the emergence of the Federation of Industry and Economics in advance, so even the same products are of better quality than in history. On the other hand, due to the change in the course of history, Japan has also designed more aircraft carriers than in history, among which the Yamato-class giant aircraft carrier, which replaced the Yamato-class battleships, is regarded by the Japanese government and the navy as a trump card to participate in the Shijie War in the future

In order to ensure that the performance was ahead of Shijie, the Japanese Navy's top brass finally resolutely abandoned the Jihua that used the two Yamato-class battleships that had already completed part of the hull to convert into aircraft carriers, and decided to dismantle the completed parts of the two super battleships, and redesign and build the two Yamato-class giant aircraft carriers.

Having shaken off the shadow of the battleship, the Japanese Navy's designers decided to zoom in on the Daiho-class armored aircraft carrier and incorporate a number of newer designs to make it a masterpiece of considerable performance. It is worth mentioning that Emperor Shohito, who was a layman, also unexpectedly made a significant contribution to the design of the Yamato-class aircraft carrier, and after learning that the number of aircraft carried by the aircraft carrier could not meet expectations, he took it for granted and asked, "In that case, why not widen the flight deck additionally?" ”

Although the material cannot be compared with that of later generations, and the Yamato-class battleship has an external drift of only 5 meters, the flight deck has been greatly widened, so that the number of aircraft carried by it in normal conditions has reached as many as 90, and it can even carry 120 or more aircraft in the extreme state

The Yamato-class giant aircraft carrier secretly joined the Japanese Navy's combat sequence after completing a sea trial in Zuihou in October 1941, and this huge ship with amazing displacement surpassed any of the active aircraft carriers on Shijie at that time in terms of tonnage and performance, and was only slightly inferior to the Midway-class aircraft carriers built by the United States later, and at that time, the third and fourth Yamato-class giant aircraft carriers that had been further optimized were almost completed. And the Pacific War in this time and space is also more exciting than in history because of the showdown of these supercarriers

The performance parameters of the No. 1 ship "Yamato" of the Yamato-class giant aircraft carrier are roughly as follows:

Displacement: 51,200 tons (standard); 62,500 tons (full load).

Dimensions: 280 meters long (flight deck), 264 meters (waterline), 58 meters wide (flight deck), 36 meters (waterline), draft 10 meters, 5 meters drift.

Power: 4 ship-based steam turbines, 12 ship-based heavy oil boilers, 4 shafts, 204,000 horsepower.

Maximum speed: 32 knots.

Endurance: 10,000 nautical miles / 18 knots.

Establishment: 4,175.

Weapons: 12 twin 105mm anti-aircraft guns, 12 twin 40mm anti-aircraft guns, 6 quadruple 20mm anti-aircraft guns, 18 twin 20mm anti-aircraft guns, 12 single 20mm anti-aircraft guns.

Aircraft: 90/120.

Note 1: The serious, hardworking, and courageous character of the Japanese nation is now difficult to see, and during the Fukushima crisis, there was not even a single young man who was willing to take risks, so he could only let some middle-aged and elderly people go. Personally, I think that the Japanese are mainly because the blow caused by the sheep shearing by the Americans in the original Plaza Accord was too heavy, and the Japanese, who had previously wanted to rely on economic achievements to re-rise the motherland, finally recognized the reality and knew that no matter how hard they tried, as long as the United States refused to loosen the bonds on Japan, Japan would only be a dog of the United States after all, and if it was too rich, it would be cut by the Americans, and on the other hand, Japan has become a developed country after all, even if the Japanese no longer work as hard to build the country as before, It is also possible to continue to live a life of relative affluence. It's useless to work hard, and even to be unlucky, you can mix well without hard work, and the Japanese naturally start to mess around, and after a long time, after the habit is formed, the Japanese nation will be abolished (to be continued......
