readx; When the United States started construction of two battleships, as a supporting development, the two heavy cruisers that will be used as the vanguard fleet of the battlefleet in the future were also started at the Jiangnan Shipyard, the first ship was "Huatai", the second ship was "Huawu", and the name of the ship continued to use the word "Hua" in "Long Live China", "Huaxia Rejuvenation", and "World Peace", while the predecessor Huazi-class ship "Huahang" has been converted into a coastal defense training ship, and the CA heavy cruiser number and the name of the Huahang have been revoked, and the name of the ship has been renumbered as HF-5; and the name of the ship has been changed to Shichang. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoThe naming rules of the Chinese Navy are that except for the capital ships with the symbols of the country and the nation, such as the Yan and Huang Emperors, the Yangtze River, the Yellow River, Mount Tai, Lushan, etc., the rest of the heavy cruisers, light cruisers, and destroyers all use the three short sentences of Huaxia Rejuvenation, Long Live China, and World Peace. However, there are no strict naming rules for auxiliary ships such as coastal defense ships, gunboats, and training ships, and in order to distinguish them and promote the spirit of the navy, the navy has decided to name some important auxiliary ships after some important figures in the history of the Chinese navy, and the others are relatively arbitrary, such as the Yingrui training cruiser, which has always used the old name of the former Qing Dynasty and has not changed.

The Huatai-class heavy cruiser is also designed by Wei Yuan, director of the Ship Administration, and is based on the current heavy cruiser of the United States in the Navy, and has carried out a comprehensive strengthening of firepower, armor, and speed, with a design standard displacement of 15,000 tons and a full load displacement of 18,000 tons, and the firepower has been replaced by three twin turrets on the Xingshang to a triple turret, and the number of main guns has also increased to nine eight-inch and fifty-five times the number of naval guns, and the surname energy data of this main gun is roughly the same as the main gun of the Xingshang class. Just a slight reduction in the weight of the gun. The thickness of the main armor belt on the side was six inches, and the horizontal armor reached three inches. Although domestic power units are used in terms of power, due to the increase in the tonnage of ships, the Huatai-class heavy cruiser is enough to accommodate a crew of up to 110,000 horsepower. And this power crew is even less than the Yandi-class battleships by 20,000 horsepower, so the maximum speed of the Huatai-class heavy cruisers can reach 32 knots.

Compared with the Xing-class heavy cruisers in the Chinese Navy, which have been in service for five years, the standard displacement of the Huatai-class heavy cruisers has been increased by 5,000 tons, the firepower has also increased from six to nine, and the speed has increased from 29 to 32 knots. And these are not the most important, the most important thing is that the Huatai-class heavy cruiser has increased the standard displacement of up to 5,000 tons, most of which is used for the strengthening of protection, so that the Huatai-class heavy cruiser has six-inch thick side armor and three-inch horizontal armor, and the protection capability is much higher than the four-inch side armor and forty mm horizontal armor of the Xing class heavy cruiser, and it is even close to the protection level of the American Lexington-class battlecruiser. The comparison between the two is that the Huatai-class heavy cruisers only have one inch less on the side armor, while the horizontal armor is equal.

In fact, considering that the role of the two navies in the two countries is almost always used as avant-garde fleets, once these two ships meet, the Huatai-class heavy cruiser will not be able to stop the sixteen-inch cannon on the Lexington-class battlecruiser, but the armor of the Lexington-class attack will also not be able to stop the eight-inch and fifty-five-fold main guns of the Huatai-class heavy cruiser. The estimated cost of the Huatai-class heavy cruisers is 15 million yuan, which is equivalent to 7.5 million US dollars, while the estimated cost of the Lexington-class battlecruisers is 40 million US dollars, a difference of 5.3 times, and the five Huatai-class heavy cruisers will definitely play a greater role than one Lexington-class battlecruiser.

It is precisely because of the outstanding surname-price ratio that the Chinese Navy has vigorously developed 15,000-ton heavy cruisers with balanced protection capabilities, and in fact, not only China has seen the potential of heavy cruisers, but the navy has also seen the potential of heavy cruisers, and it has now started construction and built heavy cruisers of more than 10,000 tons.

The reason why heavy cruisers in history give people an expensive and impractical image is because the Washington Naval Treaty stipulates that heavy cruisers shall not exceed 10,000 tons, and the guns shall not exceed eight inches, so the shipbuilding designers of various countries are tied hand and foot, either choose firepower or protection, and all countries choose firepower in comparison with the two, so there is a treaty heavy cruiser, which is equipped with eight-inch naval guns but the protection ability cannot even be protected by six-inch naval guns. The Xing-class heavy cruisers in service in the Chinese Navy are very similar to the treaty heavy cruisers, both of which are types with firepower but without protection. But when the tonnage of the heavy cruiser rises to the standard displacement of 15,000 tons, then the heavy cruiser can have a fairly balanced firepower and protection, and the heavy cruiser of this specification is a veritable heavy cruiser, and the heavy cruiser of this specification can be used as the avant-garde fleet of the main fleet, which can well meet the needs of naval strategy.

Shut down

In the second phase of the Navy's development plan, in addition to two battleships and two heavy cruisers, there are two 6,000-ton reconnaissance air defense cruisers, this light cruiser is not the design of Vice Admiral Wei Yuan, Director of the Ship Administration, but the design of Rear Admiral Qin Yi, Deputy Director of the Ship Administration, Qin Yi graduated from the Fuzhou Shipbuilding Bureau in his early years, and then went to the United Kingdom to study, participated in the construction and design of many warships in the former Qing Dynasty, and he also participated in the ordering of warships and other work when the Navy was rebuilt at the end of the Qing Dynasty. After the Nationalist Army accepted the Jiangnan Shipyard, he was appointed as the shipbuilding director of the Jiangnan Shipyard, participated in the construction and design of the Suiding-class destroyer, and then accepted the invitation of Sa Zhenbing to work in the Department of Naval Affairs of the Admiralty, with the rank of colonel, and then participated in important work as the deputy designer of the Chay-class light cruiser, and then he successively put forward a number of light cruiser design schemes and aircraft carrier design schemes, which was valued by Sa Zhenbing, the chief of the Admiralty, and was promoted to rear admiral last year, After the second phase of the Navy's development plan was proposed, his 6,500-ton light cruiser design was adopted by the Navy, and at the same time, the 20,000-ton aircraft carrier plan he designed was also adopted by the Navy, and he was promoted to deputy director of the Navy's Naval Ship Administration.

Rear Admiral Qin Yi's design type was mainly biased towards light ships, and because he was much younger than Wei Yuan, he was more enlightened in style, which was different from Wei Yuan's traditional design style.

For example, in the same 15,000-ton heavy patrol design scheme, Rear Admiral Qin Yi's design plan was to use twelve eight-inch guns, and required the speed to be increased to 35 knots, in order to achieve the above goals, part of the protection was sacrificed, but the navy gave up this high-firepower and high-speed design after thinking twice, and instead adopted Wei Yuan's regular balanced design.

Affected by the failure of the two design schemes of battleship and heavy cruiser, in the design of the 6,500-ton light ship, Rear Admiral Qin Yi's design was much more conservative, and he planned to use four triple turrets with a total of 12 five-inch and 40-fold high-level dual-purpose guns, instead of a larger-caliber six-inch main gun, which was mainly because he advocated that in order to take into account the needs of air defense and artillery warfare, the high-level dual-purpose gun should be used as the main gun in the future light ships, and the secondary guns on large warships should also use the high-level dual-purpose gun. This concept was adopted by the Chinese Navy, which valued the role of aircraft, and was prepared to equip the two new light cruisers and six destroyers with high-level and dual-purpose main guns, as well as the secondary guns of heavy cruisers and battleships.

Due to the factors of R&D cost and ammunition generality, Qin Yi once again put forward the plan of universal naval guns, planning to unify the secondary guns on battleships and heavy cruisers, as well as light cruisers and destroyers. However, due to the problem of caliber, this main gun makes it troublesome to shoot at the air, and it cannot be equipped with destroyers, so the Shanghai Arsenal has come up with the second Gaoping dual-purpose naval gun, which is a five-inch and fifty-fold naval gun, and this naval gun is the main gun on the Suiding-class destroyer, and the Shanghai Arsenal has also made small modifications to make it available for anti-aircraft shooting.

And these two guns failed to satisfy the navy, mainly because the two of them are too poor in the air surname, so the Shanghai Arsenal had to specially develop a five-inch and forty-fold caliber high-level dual-purpose gun, at this time to get the satisfaction of the navy and sent a large number of orders, ready to use this gun for the Yandi-class battleships, Huatai-class heavy cruisers on the secondary guns, but also for the new 6500-ton Xiahang-class light cruisers, the new 1500-ton Wanhui-class destroyers on the main gun.

In addition to the two battleships ordered in the United States, the other three warships have started construction at the Jiangnan Shipyard, Mawei Shipyard and Qingdao Shipyard in China.

In addition to the traditional artillery warships above, there are aircraft carriers that appeared not long in the history of warships, China's aircraft carrier road began in 1915 with the Taishan modified aircraft carrier, after three years of testing and training has provided a lot of valuable experience for the Chinese Navy's aircraft carrier development road, and the time entered 1919, it was said that "Ben and Britain have successively started to build aircraft carriers, the Chinese Navy naturally does not dare to lag behind, with a large number of test data of the Taishan modified aircraft carrier, And with Chen Jingyun's personal instructions, the basic data of this aircraft carrier began to be determined very early, such as the speed must reach 30 knots, such as expanding the hangar capacity to carry more aircraft, such as all-through deck design, etc., and although the aircraft carrier hull is 20,000 tons tall, it does not need to be equipped with a large caliber of main guns, and the Admiralty does not even equip the aircraft carrier with eight-inch guns like other countries, but only plans to equip some of the five-inch and forty-fold high-level dual-purpose guns for self-defense.

Part of its internal design is more about anti-sinking and how to expand the capacity of the aircraft, which is not too difficult for China's shipbuilding industry, and even the technical difficulty of building this 20,000-ton aircraft carrier is far less than the technical difficulty of building the two 15,000-ton heavy cruisers.

Affected by the fact that the first modified aircraft carrier Taishan was named after mountains and rivers, the State Military Commission also named the first domestic aircraft carrier after mountains and rivers, with its first ship named Huashan and the second ship named Hengshan.

In addition to making Chen Jingyun excited, the construction of the Huashan-class aircraft carrier did not cause any waves at home and abroad or even among the domestic people, and people are now turning all their attention to the Yandi-class battleships under construction in the United States, and in the domestic construction, people are also paying more attention to the construction of the Huatai-class heavy cruiser, as for the larger circle, the ship-building is higher than the Huatai-class 15 million Chinese yuan, and the Huashan-class aircraft carrier, which has reached 18 million Chinese yuan, is not of much attention. In the final analysis, this was because the people at that time, including the Chinese Navy itself, regarded aircraft carriers as reconnaissance auxiliary forces, rather than the main force of the navy, and for a group of naval generals such as Sa Zhenbing and Cheng Biguang today, the important surnames of these two aircraft carriers are not as important as those two heavy cruisers, and if it were not for Chen Jingyun's strong request, I am afraid that the navy would have moved the funds for building aircraft carriers to other types of ships.

However, in Chen Jingyun's heart, other ships of the navy, including those two battleships, cannot be compared with these two Huashan-class aircraft carriers, and if the Chinese Navy wants to compete with the navies of the great powers, it can only pin its hopes on these two aircraft carriers, and other battleships, heavy cruisers, light cruisers, and even submarines cannot make the Chinese Navy stand at the top of the world.
