In the past, these first-class protection cruisers were not bad compared to the previous patrols with key protection, and the price was lower, the speed was higher, and the cost was low, which was a good warship for the Krull Kingdom Navy that needed to maintain a large scale and escort the whole world.

But with the rapid spread of hardened armor and rapid-fire gun technology, they quickly became obsolete.

The two naval battles of Beauva, whether it was the Daheng Imperial Navy itself, or the first-class protective cruisers and second-class protective cruisers of the Gafia Imperial Navy, were all very unbearable, and their dome armor protection layout could not withstand the dense rapid-fire artillery fire at all.

Coupled with the fact that the patrol formation of the Great Heng Imperial Navy performed so well, the fool also knew that a large number of countries would definitely follow suit, and at that time, a large number of first-class protection cruisers in the Krull Kingdom would fall into the embarrassing situation of being many and useless.

At this time, they needed a new type of warship to replace the large number of first-class cruisers and a new type of cruiser to fight against the navy of the Great Heng Empire and other countries.

There is no doubt that this new battleship can only be a cutting-edge armored cruiser!

Not only do they have to engage in a new type of patrol, but they also have to engage in a new type of patrol that can completely suppress the navy of the Great Heng Empire and the navies of other countries.

Under such circumstances, the navy of the Krull Kingdom did not hesitate for too long, and soon began to quickly start designing a variety of armored cruisers.

For example, in order to fight against the Fengyang-class armored cruisers of the Daheng Imperial Navy, and also to fight against the large-tonnage armored cruisers of potential other countries, they thought it was necessary to have a faster, larger, and more powerful battleship, for this reason, they expanded the original Frank-class armored cruisers to be equipped with two single-mounted 230 mm rapid-fire guns and fourteen 150 mm rapid-fire guns. So the tonnage of this thing has reached more than 14,000 tons, and it can run a full twenty-three knots.

In terms of speed, it can beat the Fengyang-class of the Daheng Imperial Navy, because the Fengyang-class is only twenty knots!

But there is a give-and-take, and in terms of firepower, it is not as good as the Fengyang level.

However, this kind of large-tonnage armored cruiser is expensive, it is impossible to build a dozen and a dozen, and at the same time, among the armored cruisers of other countries, there are quite a lot of armored cruisers of about 10,000 tons or even seven or eight thousand tons, and the typical example here is the Crane-class armored cruiser of the Daheng Imperial Navy, this broken thing is not only the Daheng Imperial Navy itself has been equipped with eight, but also four will be put into service this year, and other countries have also ordered a lot, and the total scale of service in the world's countries must be able to reach more than 20 ships.

At the same time, other countries also have plans to build 10,000-ton cruisers, and there are quite a few, so the Navy of the Krull Kingdom also needs an armored cruiser that can maintain the number, so they have made a reduced version of the 10,000-ton cruiser.

But even if it is reduced, it still reflects the characteristics of the navy of the Krull Kingdom as always, that is, it pays great attention to speed, so this 10,000-ton armor can run twenty-three knots......

Even the firepower is inferior to the Crane-class armored cruisers, and the protection is not as good!

But people are going to build a dozen!

It can also be seen from the construction of these two levels of armored cruisers that the navy of the Krull Kingdom did not expect any decisive battle or anything like that, but used to suppress and resist the loading cruisers of other countries and protect the shipping routes, and the number one goal was to counter the breakdown.

As for the fleet decisive battle, they had a bunch of battleships of the first rank!

When the navy of the Kingdom of Krull began to continue to develop mixed main gun battleships and rapid-fire main gun patrols because of the Battle of Bova, the Keel Imperial Navy, the Valia Imperial Navy, the Olisa Imperial Navy, and the Gafia Imperial Navy all developed towards mixed main gun battleships and rapid-fire main gun patrols without exception.

Interestingly, in fact, another newly commissioned capital ship of the Daheng Empire was also exposed this year, that is, the Jinghe full-rapid-fire gun battleship.

However, this battleship did not cause much of a sensation, but it just made many countries think that the Daheng people are really crazy to engage in patrolling!

That's right, no country treats the Mirror River as a battleship, even the Daheng Imperial Navy itself is thinking about reclassifying this thing as an armored cruiser.

After all, it is equipped with a rapid-fire cannon of the patrol level, although there are a little more in number, a full six twin equipped with twelve.

But this is still only patrol-level firepower, and there is no 300 mm caliber tube, so I am embarrassed to say that I am a battleship?

As for the strong firepower, in addition to the four main guns, the Manning-class battleships of the Krull Kingdom Navy have twelve second-level main guns, and the twelve rapid-fire main guns of the Mirror River are nothing special.

Moreover, in the era when there was no unified fire control, this kind of battleship with a bunch of second-class main guns could only wash the deck at close range, and the combat effectiveness was actually not much stronger than the Fengyang-class armored cruiser of more than 12,000 tons!

Anyway, it's all for deck washing anyway, and what the Jinghe can do, the Fengyang class can do, and it's cheaper!

The reality is also that the battleship Jinghe, which does not have unified fire control, has behaved since it was put into service, and the two hundred and fifty mm shells thrown at a distance of four or five thousand meters are enough to make any enemy ship doubt his life.

However, it was very embarrassing to conduct long-range live-fire tests, because the number of main guns was so large and the rate of fire was so fast that the gunners of each artillery group could not even observe the water droplets stirred up by the shells fired by their own guns.

So that it is impossible to obtain shooting elements, and when firing rapidly, the long-range design has a very low hit rate, and it is not even as good as using only a few guns to aim slowly, so that at least you can see the water droplets, and it will not mess up!

But what is the use of the twelve rapid-fire guns?

In the end, the navy of the Great Heng Empire quickly came to the conclusion that this thing could only be used for deck washing close before the installation of unified fire control, and the efficiency of long-distance artillery bombardment was too low to bear the heavy responsibility of the decisive battle of the battleship.

However, this broken thing is 16,000 tons, and the original cost is more than 7 million, and it is not willing to only wash the deck in the future, so the navy can only count on this battleship to install unified fire control in the future, and then upgrade the main gun above, don't count on increasing the caliber, the ammunition car and gun mount are already designed and finalized, and there is no way to change it.

However, it is possible to upgrade the 250 mm 30 times caliber naval gun to the same caliber 45 times the caliber naval gun, although it will increase the weight, but it can also be balanced by reducing the number of main guns, the number of secondary guns, and the amount of coal loaded.

After this upgrade, it can barely be used in long-distance artillery battles.
