readx; Chen Jingyun nodded: "Yes, localization does not necessarily mean that it is necessary to produce in enterprises controlled by domestic capital to be considered localization, and when Americans come to China to produce, it is also localized!" ”

Many people have some different views on the so-called localization, which in a narrow sense means that the domestic national capital includes the products produced by companies operated by state capital and private capital. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoAccording to this standard, even the products produced by Wuhu Iron and Steel Company cannot be regarded as domestic goods, because the main controlling shareholder of Wuhu Iron and Steel Company is the Bethlehem Company of the United States.

In a broad sense, domestic goods, that is, as long as the factory is built on Chinese soil, the workers choose Chinese, although the technology and capital are still foreigners, but the products produced can also be counted as domestic goods.

Perhaps for ordinary people, the former is domestic, but for Chen Jingyun, as long as the factory is built on Chinese soil and produces products, it is all domestic. Whether it is controlled by private capital or foreign capital is secondary.

The point is: China is able to produce and use these products!

The same concept has also been applied by Chen Jingyun to the construction of railways, over the years China's large-scale railway construction has been a Sino-foreign joint venture model, these railways will be completed by foreign capital will certainly take away a lot of operating profits, but for Chen Jingyun, as long as these railways on Chinese soil, as long as these railways can bring economic development to the areas along the railway, then it is enough.

The purpose of building railways is not to make money with railways, but to use railways to boost the local economy and consolidate national defense.

The same is true of Wuhu Iron and Steel Company, although most of the profits are divided by Bethlehem, but what is brought to China is advanced steel technology.

It is shameless to say that if a war breaks out, whether private capital enterprises or foreign-funded enterprises will all be included in the national defense economic system to serve the country.

Based on these concepts, Chen Jingyun's definition of domestic goods is quite relaxed!

However, the Navy did not expect this before, and the Navy had been trying to introduce the technology of 16-inch naval guns, but they had adopted the Shanghai Arsenal to accept the technology, but they did not think of letting the Americans directly set up a naval gun production plant in China.

However, when I thought about it, I was relieved that my naval artillery technology had also developed in this way.

Sa Zhenbing said: "Understood, then I will contact the United States to see if I can let them directly set up a factory in China!" ”

Chen Jingyun nodded: "Hmm! ”

At this time, Sa Zhenbing continued to talk about the design of the new battleship: "The main gun layout and armor layout of the new battleship largely follow the layout of the Yandi-class battleship, and the overall protection capability is limited by tonnage, which has been greatly weakened. However, according to the experience of naval battles in the East China Sea and many related experiments, the Navy believes that the distance of naval battles in the future will be further increased, and will be carried out at a distance of 20,000 yards to 30,000 yards or even longer, so the weakening of the side armor is acceptable, and the relative protection of horizontal armor is further increased! ”

As a result, the armor on the side of the new warship was 11 inches thickest at the thickest point, with a 15-degree inclination, and the front of the turret was 15 inches armored, and the horizontal armor was further strengthened, and the main horizontal armor reached 6 inches thick. At the same time, due to the increasing threat of torpedoes, the anti-torpedo armor belt is also used in the side underwater, although the protection ability of the new warship in this design is not as good as that of the Yandi class in the medium and short distances, but the protection ability at medium and long distances, especially the horizontal protection ability, is more than the Yandi class! ”

Chen Jingyun also knew that the battle distance of the battleship would become larger and larger, so he agreed with this statement, nodded and motioned for him to continue.

"The power system is expected to use the new steam turbine of Shanghai Power Company, and the Shanghai Power Company submitted the design plan of the new steam turbine, if the technology is mature, the domestic steam turbine will not be worse than foreign products. However, in order to prevent Shanghai Power Company from being unable to complete the research and development of new power in time, it also contacted Parsons Company in the United Kingdom, so that it can be replaced with imported power at any time when the domestic power is not up to standard! ”

The power system has always been a shortcoming in China's shipbuilding, although it is also a shortcoming in the firepower system, it is not possible to produce large-caliber naval guns, but there is no problem with small and medium-caliber naval guns under eight inches, but this power system is not very good whether it is loaded on battleships or heavy cruisers or light cruisers or even destroyers, and there has always been a gap compared with similar foreign products. This gap is tolerable on auxiliary ships, but not on battleships with the heavy weapons of the country. The Department of Ship Administration has already calculated that if the existing steam power system of the Shanghai Power Company is adopted, the maximum speed of the new warship in the initial design scheme is even 27.5 knots, and it will not be able to meet the 28 knots in the design requirements. Therefore, either Shanghai Power will come up with new products, or it can only choose to import.

Since the Admiralty was able to send this initial design plan to Chen Jingyun, it had naturally been approved in the internal discussion of the Navy, otherwise it would not have been sent to Chen Jingyun in a daze, Chen Jingyun saw it, and felt that although the speed was only twenty-eight knots lower, it was considered that it was only 1923 and knew that this speed was impossible to increase. As for other technical details of the battleship, Chen Jingyun did not pay much attention to it, such as the secondary guns, which continued to use the Chinese Navy's general-purpose Gaoping dual-purpose guns: five-inch and forty-fold guns, and the plan was to have a total of 20 guns with ten twin guns, and the number of secondary guns was the same as that of the Yandi class. The anti-aircraft guns were equipped with eight three-inch and fifty-fold anti-aircraft guns and eight triple 30-mm anti-aircraft guns.

The final design scheme was: 35,000 tons of standard displacement, three triple 16-inch 45-fold guns, 11 inches at the thickest part of the side side, 6 inches at the thickest part of the horizontal armor, 10 twin 5-inch 40 times high-level dual-purpose guns, eight single-mounted 3-inch 50-fold guns, and eight triple 30-mm anti-aircraft guns. It adopts an all-oil boiler and four-axle propulsion, with an estimated maximum power output of 120,000 horsepower and a maximum speed of 28 knots. When cruising at fifteen knots, the cruising range is 10,000 nautical miles.

When Chen Jingyun approved this design plan, the navy quickly took action and immediately began to prepare for the construction work, and there was no need to even apply for special funds for building ships, because during the war, the navy had already obtained a large amount of funds for the wartime economic shipbuilding plan, including the funds for two Yaodi-class battleships, which were now used on the new battleships.

As a result, just a few months after the signing of the Washington Treaty, that is, in January 1924, the first ship of China's new generation of battleships officially started construction at the Jiangnan Shipyard, and the second ship is also expected to start construction at the Jiangnan Shipyard in March. Its first ship was named 'Shundi', and the second ship was named Zhuan, according to the principle of the first ship being named as the class name, this class of battleships is called Shundi-class battleships.

The naming of Chinese battleships is based on the names of China's ancient emperors, but the names of battleships are all named by Chen Jingyun, and Chen Jingyun does not mean that he strictly follows the order of the Three Emperors and Five Emperors, as long as he thinks it is suitable, he will use it.

The reason why China's Shundi-class battleships were designed so quickly is that in addition to the fact that there was already a large number of reserve design fee plans within the Ship Administration Department, more importantly, the Kaohsiung and Tosa were about to be completed, especially the Tosa, which was urgently continued during the war last year, has completed the main construction work, and is currently in the final outfitting test stage, and according to normal circumstances, it will be able to be put into service by the end of this year at the latest, which is not good news for the pressure of China's seas.

Therefore, the design and construction of the Shundi class are all rushed all the way, striving to be completed in the shortest possible time and then enter service in the navy.

When the Chinese Navy began the construction of a new generation of treaty battleships, the Chinese Navy, like the navies of other countries, also discussed the design of treaty heavy cruisers.

The original heavy cruisers in the Chinese Navy were 15,000-ton balanced cruisers, that is, four ships in the Huatai-class and Shiguang-class classes. However, the Washington Naval Treaty limited the tonnage limit of auxiliary ships to 10,000 tons, and also reduced the four heavy cruisers in the Chinese Navy to capital ships. And this means that China cannot continue to build heavy cruisers of more than 10,000 tons, and it can be built if it wants, but it will have to occupy the tonnage of the capital ship.

Now the tonnage of China's capital ships has been used up, and there is not much at all. With the completion and launch of the two Shiguang-class heavy cruisers and the entry into service with the Navy, the Navy is also full of contradictions over how to build the next generation of auxiliary ships.

More than ten years ago, the Chinese Navy had already played with the 10,000-ton heavy patrol equipped with eight-inch naval guns, and the Xingshang held up the sky of the Chinese Navy, but more than ten years later, this year's 10,000-ton heavy patrol made the Navy unable to see.

But if you can't look at it, there is no way, who let the treaty limit the upper limit of 10,000 tons and the upper limit of the inch of naval guns, for this reason, the Department of Ship Administration, like other countries, put forward the design plan of the treaty-type heavy cruise.

In recent years, the choice of the navies of all countries in the world is basically the same, that is, to pile up eight-inch naval guns on the hull of 10,000 tons as much as possible, and then ensure the speed, as for the protection force, it has been abandoned by the warship designers of various countries.

However, these thin-skinned high-speed heavy cruises were really reassuring to the navy, so the treaty-type heavy cruises began to discuss the relevant design from 1922, but until 1924, the final design plan was still not determined, and by this time most of the British and American treaty heavy cruises had already started.

However, fortunately, the number of heavy cruisers in China today is not large, even after the sinking of the Huatai, China still has three 15,000-ton heavy cruisers, in addition to two old Xing 10,000-ton heavy cruisers, and there is not much urgency for heavy cruisers in the first few years. However, with the passage of time, with the United Kingdom, the United States and other countries after a large number of treaty heavy cruises were put into service, it is impossible for China to rely on these heavy cruises to support the scene. Therefore, the design of the next generation of heavy cruises has become a matter that many admirals have struggled with until now.

However, just when the navy was entangled in the re-patrol of the 10,000-ton treaty, Colonel Han Tonglin, chief of the shipbuilding section of the Ship Administration Department, put forward a very interesting idea, that is, to design an aviation warship!
