Their latest model, the Kairy-class battleship, has a standard displacement of 20,000 tons, four main guns of 300 mm and 45 times the caliber, with a rate of fire of 1.5 rounds per minute, twelve second-class main guns of 250 mm and 45 times the caliber, a speed of 20 knots, and the use of nickel steel hardened armor, and its combat effectiveness is off the charts!

And the battleships of other countries with mixed main guns are a little worse.

Also using the 300 mm caliber main gun are the Orissa Empire, the Gafia Empire, the Orlan Kingdom and some other medium-sized countries, but the 300 mm caliber main guns they use are far inferior to the main guns of the Daheng Empire and the Krull Kingdom in terms of performance, not that their main guns are only 300 mm and 40 times the caliber main guns, but because they generally use ordinary loading mechanisms, they cannot achieve omnidirectional loading, and the rate of fire generally stays at one shot a minute,

Well, the main gun loading mechanism exported by the Daheng Empire is also similar to this, with a rate of fire of about one shot per minute.

The caliber of their second-class main guns is also relatively uniform, and rapid-fire guns with a caliber of 170 mm are generally used as the second-level main guns.

Why?

Because they haven't come up with a large-caliber rapid-fire main gun yet.

For example, the Gafiya Empire, they were able to break through the technology of 120 mm rapid-fire guns in the 12th year of Qiansheng, and only 150 mm and 170 mm rapid-fire guns were made in the 14th year of Qiansheng, and these rapid-fire cannons have a characteristic, that is, they can be manually loaded.

As for the larger-caliber rapid-fire gun, they haven't come up with it yet, because that thing involves more things, in addition to the stationing and re-entry of the main gun, it also needs the cooperation of the loading system, and it is a huge systematic project to really do it.

The countries on the Blue Star that want to quickly get large-caliber rapid-fire guns out of the country are actually only the three traditional powers, as for the Daheng people themselves, they have been secretly doing it for many years in advance.

Needless to say, the three traditional powers, the Krull Kingdom, and the Kyle Empire and the Valia Empire have been more embarrassed when they built ships in the past two years.

Because they haven't come up with a rapid-fire main gun of 300 mm caliber for the time being, but they have barely made a rapid-fire main gun of more than 200 mm.

But there are two countries that are more special, and that is the Kkarl Empire and the Walya Empire.

These two countries are the three traditional industrial powers, and if it were not for the strong rise of the Great Heng Empire, they would be firmly in the second and third places in the world.

Like the Krull Kingdom, they developed large-caliber rapid-fire guns relatively late, but they did not have the strong technical background of the Krull Kingdom, and in just two or three years, they caught up with the large-caliber rapid-fire cannon technology that the Daheng Empire had spent seven or eight years developing.

Until now, their 300-mm rapid-fire gun technology has not been solved, but they are not, like other countries, they can't even make a rapid-fire gun of more than 200 mm.

Therefore, the road of shipbuilding in the past two or three years of these two countries has been very tangled, and even a little repetitive.

In the case of the Kekel Empire, for example, the first few battleships with mixed main guns were traditional 300 mm main guns with 200 mm secondary guns, and later several traditional 300 mm main guns with 230 mm secondary guns were started.

But after they came up with a two-hundred-and-fifty-millimeter rapid-fire gun, they were a little entangled.

The rate of fire of the traditional 300-mm main gun is not enough, and the rate of fire of the 250-mm rapid-fire gun is higher, but the power is somewhat insufficient.

In the end, they gritted their teeth and still thought that the rate of fire was more important, so they began to build a relatively special six-gun battleship, using three twin 250 mm naval guns as the main gun and a 170 mm rapid-fire gun mixed main gun battleship.

Don't look at the small caliber of the main gun of this kind of battleship, but they are also big guys of more than 15,000 tons, and their combat performance is not bad.

Later, on the basis of this kind of battleship, the Kehl Empire built battleships with a tonnage of more than 17,000 tons, equipped with six 280 mm rapid-fire main guns and many 230 mm secondary guns.

Their six-main gun battleships seem to be the same as the six main guns of the Great Heng Empire themselves, but in fact, the concept is very different.

This depends on the difference between the secondary guns of the two sides.

Their six-gun plan was that they could not get a 300-millimeter rapid-fire main gun, so they were forced to use a smaller-caliber rapid-fire main gun, and at the same time, in order to ensure firepower, after all, everyone's battleships were 15,000 tons or more these days, and the newly built ones were 17,800 tons or even 20,000 tons.

If you get four second-class main guns, and the little guy in his early 10,000s comes out, I'm afraid that he will be laughed at by other countries.

When other countries see you little guy, they probably don't bother to use the main battleship against you, just send an armored cruiser out, after all, the main forces of the powerful countries in these years are all starting at 12,300 tons, and 14,500 tons at every turn.

But the Great Heng Empire is different, their six-gun battleships are purely for upgrading and refitting in the future, and then conducting long-distance operations.

Of course, these six-gun battleships are also transitional for the Kell Empire, and their target is still equipped with rapid-fire main guns of more than 300 mm caliber and large mixed main gun battleships with a tonnage of more than 20,000 tons.

Judging from the development of contemporary warships in various countries, the top mixed main gun battleships of various powers have good combat effectiveness, especially in the classic combat distance between 5,000 and 7,000 meters, which can fully exert their powerful firepower.

At a distance of 5,000 to 7,000 meters, the Luohe-class battleships and Fengshan-class battleships, which had six main guns but only some 150-millimeter secondary guns, really couldn't beat the Kaili-class battleships of the Krull Kingdom Navy without unified fire control.

But all this has changed after the unified fire control system was successfully developed and installed on the ship!

In the 14th year of the reign of Qiansheng, the Daheng Imperial Navy installed the first unified fire control system on the Jinghe and conducted numerous live-fire tests.

After the successful test, the Daheng Imperial Navy quickly ordered six sets of the first batch of unified fire control systems for four Luohe-class and two Fengshan-class battleships with six main guns.

Today, these six-gun battleships have been fully equipped with a unified fire control system, and after live-fire tests, although their six main guns are still a little less, they can barely meet the needs of unified fire control and sighting, so as to engage in long-distance combat.

But all this, the outside world does not know anything about it!

They knew that the Great Heng Empire had a group of six-main gun battleships, and they also knew that the main guns were extremely powerful, but they didn't know that these six-gun battleships were not born for medium-distance engagement, but for long-distance engagement.

They didn't even know that the Daheng Empire still had a series of unified all-heavy artillery battleships such as Ningyu-class battleships, and they had already begun to serve one after another.

Of course, other countries are estimated to have their own secret plans, such as the latest Kairy-class battleships exposed by the Krull Kingdom, which are all battleships that started construction the year before last and were commissioned this year.

And after the Kaili-class battleships to the present, there will definitely be an updated ship-building plan for the Krull Kingdom Navy in the past two years, but what they have built, only they know by themselves, at least the intelligence department of the Daheng Empire has not been able to know the true face of their Kairy-class battleship follow-up ships.

After all, the special terrain of the Blue Star makes the navy very important, and it is normal for the new warships in the navy to be widely valued by all countries.
