readx; On August 16, 1921, the two battleships Yandi and Huangdi, which China had ordered from the United States, returned to China smoothly, and when the two cutting-edge warships arrived in Shanghai, tens of thousands of people arrived at the Shanghai docks, in order to witness the majesty of the two battleships. Pen, fun, pavilion www. biquge。 info

The battleships Yandi and Huangdi were already the darlings of the Chinese media almost when the second phase of the naval development plan was first proposed, and the Chinese navy often put these two battleships and two self-built Huatai-class heavy cruisers in newspapers in order to gain the support of the domestic public, attract more outstanding talents to join the navy, and compete for more military spending for the navy.

Although the data of these warships are absolute military secrets and cannot be disclosed to the outside world, the general data can still be said, such as the use of the latest 16-inch naval guns of the United States, such as the displacement of up to 40,000 tons, and according to the propaganda of the Chinese Navy, once these two battleships are built, they will be the most advanced and most powerful battleships in the world, and in fact this is indeed the case.

The standard displacement of the Yandi-class battleship reached 40,000 tons, using nine 16-inch and 50-fold naval guns, and it also had up to 12 inches thick side armor and 5 inches thick horizontal armor, and more importantly, its speed reached an unprecedented 28 times. Although due to the technical limitations of the power system, it could not reach the 29 knots when it was designed, but it still maintained a high speed of 28 knots. This is a battleship with a fairly balanced and outstanding firepower and maneuverability, as well as protection capabilities.

At the same time, the two Nagato-class battleships that were commissioned last year and this year were only two or two thousand tons in standard displacement, and their guns were only 16 inches and 45 times that of the four naval guns, and they were equipped with eight twin guns, and their speed was only 26.5 knots. The side armor is the same as that of the Yandi-class battleship, and the horizontal armor is only three inches, which is a cut off from the Yandi-class five-inch.

The standard displacement of the latest Colorado-class battleship in service in the United States is also 32,000 tons, and it is also the firepower of four twin-mounted eight sixteen-inch 45 times the firepower of the ship, according to the design standards of the American turtle speed battleship, the Colorado-class battleship is only 21 sections, but the protection capability is much better, the side side is 13.5 inches thick, and the horizontal armor is limited by early design ideas and is only 3.5 inches.

Britain's latest cutting-edge battleships were completed in the middle and late stages of World War I, the revenge class, with a standard displacement of only 28,000 tons, and the naval guns were eight fifteen-inch forty-two times the naval guns, but the British Admiral-class battlecruisers were mostly there, and their No. 1 and No. 2 ships were commissioned in 1919 and 1920 successively, and the No. 3 and No. 4 ships were ordered to stop construction in 1918 after the war was about to end and the German High Seas Fleet could not threaten the British Home Fleet, leaving only the No. 1 and No. 2 ships with faster progress. And its first ship was the famous battlecruiser Hood in later generations.

When the Hood was commissioned in 1919, it became the largest warship in the world with a standard displacement of 42,000 tons, and even two years later, China's Yandi-class battleships had a standard displacement of only 40,000 tons. The Hood-class battlecruisers had four twin eight fifteen-inch forty-two guns, a speed of up to thirty-one knots, and twelve inches of armor on the side sides, but the horizontal armor was thinner, only three inches thick, and in order to achieve a speed of thirty-one knots, the internal protection on the Hood was actually substandard. Don't look at the 'Chinese Yandi-class battleships and the Nagato-class battleships in this book are also 12-inch side armor, but their internal protection design is designed according to battleship standards, and the internal protection is much better than that of the battlecruiser Hood. The Yandi-class battleships took into account the needs of long-distance artillery battles, and raised the horizontal armor from the common three inches at that time to five inches thick.

Therefore, although the Yandi-class battleship is not the largest battleship in the world, with its nine sixteen-inch and fifty-fold naval guns, as well as its speed of twenty-eight knots and not weak protection ability, it is enough to make him the most powerful battleship in the world.

In fact, the battleships of the same class as the Yandi-class battleships are the South Dakota-class battleships under construction in the United States, the Kaga-class battleships and the Ise-class battleships that are under construction, and the British N3 battleships, which are under construction in various countries, are the comparison objects of the Yandi-class battleships.

It's just that the two battleships ordered by China started construction earlier, and the construction speed was faster, and they were commissioned a year or two earlier than them.

"With these two warships, our navy can have no worries about coastal defense!" When Admiral Sa Zhenbing returned home from these two battle armors, he was full of confidence and promised the people.

When these two Chinese battleships returned to China, they said that they had stepped up the construction of the Kaga-class battleships and that they would strive to complete the service of the Kaga-class battleships within a year, but in their hearts, they had already fallen behind before they were completed, and what was really used to counter the South Dakota-class battleships of the United States and the Yandi-class battleships of China was the Ise-class battleships that had just begun to be built.

Although it is a backward country, the Chinese Navy did not stop the pace after the second phase of the naval development plan, and the Chinese Navy had already put forward the third phase of the naval development plan in 1920, and put forward the plan of building two cutting-edge battleships and four heavy cruisers and two aircraft carriers independently.

Shut down

Chen Jingyun originally did not plan to build so many battleships, but at that time, Britain and the United States had already proposed to limit naval armaments, and Britain and the United States also strongly demanded that China must also participate in the naval treaty, otherwise a country with two battleships would not have signed this treaty if it had left it to be outside the naval treaty.

Based on the fact that China was about to participate in the Washington Naval Treaty, in order to be able to obtain more tonnage in the naval treaty, and knowing that these warships could not really be built, Chen Jingyun did not plan to make some paper plans, so he approved the third phase of the development plan proposed by the Navy.

And now China is ready to develop for many years, has mature technology Jiangnan Shipyard started the first domestic battleship, although its main gun still needs to be imported from the United States 16-inch guns, fire control system also needs to be imported, the proportion of parts and components of the whole ship accounted for less than 30%, the remaining important parts are all imported, but this does not affect China's idea of building its own battleship, in fact, it is okay if it can't be built, because Chen Jingyun did not expect this battleship to be completed. The battleship was named Yaodi after a slight improvement based on the Yandi-class battleship, and the design was formalized in September, the month after the Yandi-class battleship returned to China.

The battleship Yaodi officially started construction at the Jiangnan Shipyard in December 1921!

Long before the construction of the battleship Yaodi began, the construction of two heavy cruisers and two aircraft carriers in the third phase of the Chinese Navy's development plan had already started in the first half of the year. However, heavy cruisers and aircraft carriers are the top priority of the development of the Chinese Navy, so when the design of the Yaodi battleship has not yet been completed, the new generation of aircraft carriers improved from the Huashan-class aircraft carrier has already completed the design in 1919, and the construction began in April 1921. The construction of two heavy cruisers, improved from the Huatai-class heavy cruisers, also began in the first half and second of the year.

In 1920, countries began to negotiate to limit naval armaments, and in order to catch up with the formal signing of the naval treaty, they all accelerated their own construction, and in early 1922, Ben desperately rushed to complete the construction of the battleship Kaga and a Amagi-class battlecruiser, and directly entered the naval service before there was time for sea trials, and the following month, a South Dakota-class and a Lexington-class battlecruiser in the United States were also completed and put into service. At this time, the treaty had not yet been formally signed, and various countries had successively proposed warships of larger caliber and greater tonnage, such as the No. 13 battleship plan, although the nineteen-inch cannon planned to be equipped with it appeared during the test firing and forced the ship to return to the eighteen-inch road, but the battleship equipped with the eighteen-inch gun had already been proposed to the construction of various countries, and the United States was the same, and even the United Kingdom, which was financially tight after the war, was not in the pants pocket and followed the development of the N3 battleship.

However, this irrational naval race was never normal, and after many negotiations and exchange of interests, in October 1922, the countries finally signed the Washington Naval Treaty.

The treaty stipulates the maximum tonnage of the capital ships of the navies of various countries, and Britain and the United States have the same 600,000 tons, which is 450,000 tons, France and Italy have 200,000 tons, and China has also obtained 150,000 tons. He said that Ben tried his best to achieve the ideal of reaching 75 percent of the United States, but this was based on the threat of the Chinese navy at the same time. For the U.S. Navy, after achieving the same tonnage as the United Kingdom, it represents that the United States is on a par with Britain, and more importantly, the dissolution of the British Alliance after the Washington Naval Treaty, which is the biggest gain of the United States.

France and Italy make soy sauce, because although they were given 200,000 tons of tonnage, they had to continue to build if they wanted to reach this tonnage.

As far as China is concerned, although the tonnage of the capital ship is the least, it also has 150,000 tons, which counts all the warships of more than 10,000 tons in the Chinese Navy, and the two heavy cruisers in the third phase of the naval development plan are also counted into the capital ships, because the treaty stipulates that in addition to aircraft carriers and capital ships, other combat warships shall not exceed 10,000 tons and eight-inch naval guns, so that China's two Huatai-class heavy cruisers in service and the two heavy cruisers under construction are counted into the capital ships. Although China tried hard to say that the heavy cruiser was only equipped with eight-inch guns and not capital ships, the United States and Britain said that they would also build a large number of eight-inch gunboats with balanced protection of more than 15,000 tons in the future, so they insisted that the upper limit of auxiliary ships was 10,000 tons and eight-inch naval guns, but in order to compensate, China agreed to increase the tonnage of capital ships from 100,000 tons to 150,000 tons. However, in order to prevent China from using the tonnage of these heavy cruisers to start building new battleships, it is clearly stipulated that during the treaty period, these 15,000-ton heavy cruisers will be the same as the battleships of other countries, and they must meet the age of 20 years before they are allowed to build replacement ships, and the replacement ships are not allowed to exceed 15,000 tons, in other words, the total number of battleships in China can only be maintained at two, and even if there is a spare tonnage of capital ships in 20 years, battleships cannot be built, and only 15,000-ton heavy cruisers can be built.

According to the provisions of the treaty, China's capital ships can only retain two Yandi-class battleships, two Huatai-class heavy cruisers, and two new-style heavy cruisers under construction. The two former dreadnoughts in service and the two armored cruisers captured from Germany must be decommissioned, and given China's lack of training ships, China is allowed to convert one armored cruiser into a training ship, the remaining three ships must be dismantled, and the two battleships under construction in China must also be stopped and dismantled.

Compared with the tonnage of capital ships, the tonnage of aircraft carriers obtained by the Chinese Navy is very high, because China has many aircraft carriers, and the original Taishan, Huashan, and Huangshan add up to more than 50,000 tons, plus China and the two aircraft carriers under construction, which add up to 100,000 tons. Therefore, when he said that "the tonnage of China's aircraft carriers can only be limited to 60,000 tons," Chen Jingyun immediately instructed Wu Tingfang and other diplomatic representatives to leave the venue, and forced Britain and other countries to agree that China would have the same tonnage as "Ben" with 100,000 tons, which was not as good as the 135,000 tons of the United States and Britain, but was the same as the 100,000 tons of "Ben" and more than the 60,000 tons of France and Italy.

The signing of the Washington Naval Treaty is not only to limit the naval arms race of various countries, but also to rank the international status, although China has obtained the total tonnage ranked last, but can be forced to participate in the Washington Naval Treaty, this is already a proof of China's status in the eyes of the countries to improve, if it is like the former Qing Dynasty, people say, 'I don't bother to ask you to participate in the naval treaty.'

After 1922, the navies of the world began to enter the so-called period of naval falsehood!
