The secondary gun of the Jingzhou is a 150 mm 40 times rapid-fire gun, this thing is also a big killer, the rapid-fire gun project is also one of the secret projects painstakingly studied by the Daheng Empire, the gun uses smokeless gunpowder, the rate of fire of the gun can reach five to seven rounds per minute, far exceeding the rate of fire of the previous naval guns of the same caliber per minute.

When this is fired, the cannonballs are like water splashing out, dense!

And the cost of this class of ships that apply a series of new technologies is also top-notch!

The navies of other countries are reluctant to even use nickel steel, so they simply continue to use steel-faced iron armor, and the hardened armor tossed by the Daheng Empire itself is more expensive than nickel steel armor!

According to the final calculation, the estimated cost of Jingzhou is 75 million Hengyuan.

This price far exceeded the previous Endless Sea-class battleships of more than four million, and even the two later improved ones were only five million Hengyuan.

Even if it is extremely expensive, the Daheng Navy is extremely firm to finalize the plan and decided to start construction of two ships immediately after completing the preparatory work next month, and strive for the first ship to be completed and outfitted next year, and strive to enter service the year after tomorrow, the navy will be put into service within two years, and quickly open up the performance advantages of warships of other countries, and lay the foundation for the next step of the Daheng Empire's 'two oceans connection plan'.

What is the plan to connect the two oceans, in fact, is to seize and control the endless strait, and open up the sea communication between the east coast and the west coast of the Great Heng Empire.

And this is bound to be at war with the Olisa Empire!

Therefore, the navy hopes to obtain a batch of advanced warships as soon as possible, and use these advanced warships to gain strategic advantages, so as to complete the plan.

Other countries have also acquired similar technology, causing their own advantages to lose!

In fact, from the naming of the ship, it can be seen that the Daheng Empire attaches great importance to the ship.

Gyeongshu!

This is also the first time that the Daheng Imperial Navy has used the names of the thirteen states to name the main battleship, and the previous Endless Sea-class battleships were named after the coastal waters of the Daheng Empire, including: Endless Sea, Xiyanghai, Shayangwan, Xiluowan, Jingbei Bay, and Qingbei Bay, a total of six.

In the previous Daheng capital ships, there was no obvious rule in the naming, Yonglin class, these two warships used the two adjacent peaks on the famous eastern peninsula of Daheng, Yong'an Mountain and Yonglin Mountain.

In the previous unification and Luohe, the unification of the number obviously has the characteristics of the times, implying the unification of Daheng, the Luo River is the second largest river of Daheng, and the Luohe River basin is also the starting place of the Daheng unified army at that time.

As for the Pingbo, it was named by Shao Bing of Luohai County during the Civil War in Nanhai Prefecture, and the subsequent Daheng Empire Navy did not change its name, but continued.

After the subsequent unification of the Daheng Empire, preliminary rules were also made for the new warships, requiring that the naming of the capital ships, that is, battleships, should have special significance, and the names of famous mountains, seas, rivers, states, or other important symbols could be used as the name of the ship.

The names of the sea areas for a series of capital ships of the Endless Sea class are named according to this rule.

The reason why it is not limited to the name of the state or the rivers and mountains is because there are only thirteen states in Daheng, and there are not too many famous peaks in the territory, and there are only two big rivers, but the capital ships of the Daheng Imperial Navy are not only a dozen, and the capital ships in the second phase of the development plan are planned to be more than 30 ships, although it has not been completed now, and the second phase of the development plan has been made ancient, but the ambition of the Daheng Imperial Navy has always been great, so there is enough space in the small detail of the naming rules.

Cruisers, on the other hand, are named after counties and counties directly under the state, such as Luohai, Luo'an, Guang'an City, famous people's names or other titles with special significance.

As for the naming rules for lower-level lightning strike ships, patrol ships, and gunboats, they are more arbitrary, and the larger tonnage can use the name of the county or the name of a famous historical figure or other names with special significance, while some small tonnage ships are directly numbered!

Generally speaking, the naming of warships in the Daheng Imperial Navy is still relatively arbitrary, which can be seen from the fact that battleships, cruisers, and lightning strike ships can all use the names of historical figures.

After determining that the Jingzhou-class battleships were a new generation of new battleships and preliminarily planning to build four of them, the meeting immediately decided on the plan for armored cruisers.

The same selection was made from a number of candidates, and there were more candidates for armored cruisers, and even the tonnage of the six main schemes varied greatly, from the small ones to more than 7,000 tons, and the large ones were more than 15,000 tons, even larger than the Jingzhou battleship.

The firepower layout is also different, some are equipped with 300 mm guns, some are equipped with 250 mm guns, some are equipped with 200 mm guns, and some are simply equipped with a large number of 150 mm rapid-fire guns, instead of being equipped with large-caliber guns.

Because the tactical positioning and technical indicators of battleships are very clear and different, the Daheng Navy does not have clear technical index requirements for armored cruisers, only tactical positioning requirements, but there are more tactical positioning requirements. Jin Yong Chinese

The Daheng Navy hopes that the armored cruiser can confront and annihilate the enemy reconnaissance fleet in the decisive battle of the fleet, and at the same time go out to reconnoiter the enemy's main fleet, obtain vital battlefield intelligence, block the enemy's intelligence sources, and make the battlefield unilateral and transparent!

This is the core task of the armored cruiser of the Daheng Navy!

However, in addition to this core task, the Daheng Navy also hoped that at a certain moment, the armored cruisers would be organized into a high-speed guerrilla formation alone to flank the weak points of the enemy's capital ships and create favorable conditions for the decisive battle of the main fleet.

That is to say, at a certain moment, the Daheng Navy needs armored cruisers to also go up to participate in the line duel.

Considering that in recent years, many countries have also begun to follow the example of the Daheng Navy to build similar armored cruisers, second-class battleships, first-class cruisers, so the Daheng Imperial Navy needs new armored cruisers with better performance in order to gain tactical advantages in the future.

At the same time, considering that the Daheng Empire itself has begun to secretly equip rapid-fire guns, and the navies of other countries have already equipped with semi-rapid-fire guns before, it is difficult to guarantee that they will not develop rapid-fire guns, and the expected service life of warships is very long, even in the modern era of rapid technological innovation, the service time of capital ships is more than ten or twenty years at every turn.

Therefore, it is necessary to take into account the threat of rapid-fire guns of enemy ships in the future, and it is necessary to adopt the concept of comprehensive protection for this purpose, of course, this is also the case hardened nickel steel armor secretly developed by the Daheng Empire, which can save a lot of armor tonnage and make the armor area larger to achieve comprehensive protection.

If it were the previous era of steel-faced ironclad, armored cruisers would not be able to achieve full protection under the condition of ensuring firepower and speed.

But the advent of hardened armor solved this problem!

Because of the particularity of hardened armor, and many other secret projects, such as smokeless gunpowder and rapid-fire guns, have adopted code names, and the surface carburized hardened nickel alloy steel will not directly use this name with technical characteristics, but use the manufacturer's name as the name, called Luohai armor.

The Luohai Iron and Steel Works is the developer and manufacturer of this kind of surface carburized and hardened nickel steel armor, and as for the Jingzhou Iron and Steel Company, another major armor steel R&D and manufacturer in the empire, they are also working on carburizing and hardening armor, but their hardened armor has not yet been developed.

In the end, after deliberations, the armored cruiser plan reached 12,000 tons, equipped with 250 mm 35 times the caliber main gun, and at the same time equipped with 10 150 mm 40 times rapid-fire guns, and fully used smokeless propellants, No. 2 armor-piercing shells, No. 3 armor-piercing bullets and other new ammunition.

The armor layout abandoned the previous focus on protection, but followed the Jingzhou battleship to adopt comprehensive protection, but the armor belt was not so thick, and the thickest part of the main armor belt reached 200 mm.

The speed reached twenty knots.

The scheduled cost reached 6 million Heng Yuan, which is very expensive and expensive.

The ship was finalized as a Fengyang-class armored cruiser, and two were initially planned to be built.

This class of ships is actually a reduced version of the Jingzhou-class battleship, weakening the main gun fire and protection, in order to increase speed, its tactical positioning in addition to reconnaissance missions, this class of ships will be used as a high-speed warship, auxiliary fleet for a decisive battle.

After finalizing the design and construction plan of the Jingzhou-class battleship and the Toyoyo-class armored cruiser, the next cruiser and lightning strike ship will be simple.

After discussions, a cruiser with a displacement of more than 4,000 tons became the main reconnaissance cruiser in the ocean-going fleet, and it was finalized as a second-class cruiser of the Charin class, and a batch of eight ships was planned to be built in the early stage.

The Xialin-class second-class cruiser, with a dome armor design, is equipped with four 150 mm 40 times rapid-fire guns, this is set as a seven-year type 150 mm 40 times gun, and it is also the secondary gun of the front Jingzhou-class battleships and Fengyang-class armored cruisers.

As well as eight 120 mm 40 times rapid-fire guns secondary guns, in addition to carrying torpedo tubes, according to the design speed is expected to be 21 knots, the maximum speed will have to be completed or tested to know, under strong pressure ventilation 20 to 23 knots are possible.

In fact, this class of ships does not have any big characteristics, that is, it runs fast, has good protection, and has strong firepower!

But this is not because of how good the design of the ship is, in fact, the hull design is just like that, these excellent performance is entirely due to the application of a series of advanced technologies, hardened armor to bring strong protection capabilities, rapid-fire guns to bring powerful firepower, and the above two to free up more space for the power system, to install more steam engines, and finally to obtain more power.

In the end, there was such a fast, well-protected, and firepower second-class cruiser of the Charlin.

In addition to this main reconnaissance cruiser, several other cruisers of different tonnages and different purposes will be built.

There was also a two-thousand-ton unprotected all-steel third-class cruiser, an eight-thousand-ton first-class cruiser, of which the eight-thousand-ton first-class cruiser was interesting.

The name of the design scheme is "Unified caliber full rapid-fire cruiser".
