From the second-class battleship Pingbo, to the second-class battleship Unification, to the armored cruiser Chongke, and even the first-class battleship Yonglin that is still in the final outfitting.

Almost every one of these four types of warships has achieved substantial leapfrog development, which has led to a huge gap in the performance of some warships in service in the past few years compared with newer warships.

For example, the Pingbo, which was commissioned in Yongchang for 52 years, has only been in service for more than four years, but the performance of the ship is already much behind.

Even the two second-class battleships of the Unified Class that were commissioned just last year have only been in service for one year, and the No. 2 ship Luohe has not even been in service for less than a year, but the performance is already lagging behind.

In fact, this situation did not only appear in the navy of the Great Heng Empire, but also in several other naval powers.

As soon as the navies of many countries wake up, they find that the new warships they have just commissioned are outdated......

Not to mention those battleships that have already been put into service, some of them are even under construction, which have not yet been built, but they are already facing the embarrassment of being outdated.

This is because the naval technology on the Blue Star has advanced too fast in the last four or five years!

A few years ago, the Daheng Empire began to equip the battleships with rear-loading rifled naval guns, and adopted an open-air rotating turret or turret design, and almost all the naval powers followed up quickly overnight, and even their movements were larger, such as the Krull Kingdom Navy even more than the Daheng Empire's Navy, which successfully came up with a naval gun of 300 mm and 30 times the caliber a few years earlier.

This is to move the naval artillery from the era of front-loading smoothbore guns and front-loading rifled guns to the era of rear-loading rifled guns.

At the same time, there has been a major change in the layout of firepower, with the entry into service of the long-barreled rear-loading gun, the ancient shipside guns have been completely abandoned, and the design of the central gun gallery has been completely thrown into the garbage heap by the designers of warships of various countries.

At the same time, it is equipped with four rear-loading large-caliber rifled guns.

These two main artillery fire layouts have completely swept the previous messy artillery layouts into the garbage heap of history.

In addition to the firepower layout, the layout of protection has also undergone a huge change.

Five years ago, everyone was still playing happily and using wrought iron armor, but since the Krull Kingdom took the lead in applying steel-faced iron armor to warships on a large scale, it has entered the era of steel-faced iron armor overnight.

Countries quickly followed up to build steel-faced ironclad battleships one after another, and the navy of the Daheng Empire was a few years late, because of the limitations of domestic technology, it was not until the Endless Sea-class battleships that they were ready to adopt the steel-faced ironclad that had just been successfully imitated.

The power is also very changeable, the Krull Kingdom began to apply the strong pressure ventilation technology originally applied to high-speed passenger ships on a large scale to the warship, this technology is actually nothing special, so it soon caused countries to follow suit, the Daheng Empire itself is also studying the strong pressure ventilation technology, although it has been tested several times, it has also been tested on a frigate, but it is not perfect, if it is perfected, it will also be quickly assigned to a series of new warships such as Endless Sea-class battleships.

It is expected that the technology of the upgraded and improved old warships will be upgraded in the future.

The three core technologies of firepower, protection and power have been broken through in just four or five years, and the continuous breakthrough of this technology has also made the upgrading of naval warships of various countries very fast!

If you don't pay attention to this, you will find that the main battleship under construction has become outdated......

But to put it mildly, after four or five years of radical technological changes, especially after the Krull Kingdom Navy announced their King-class battleships, the tone of development of the navies of the Blue Star countries has changed and stabilized again.

What's the tone?

Plagiarize a King-class battleship!

The boss of the world has been thundering in front of him, and he has come up with a king-class battleship that is strong and has a performance that comprehensively surpasses the active and under-construction warships of various countries, what are you still tossing, hurry up and copy it!

As a result, four years after Qiansheng, the navies of all countries in the world have basically reached a basic consensus on the construction of capital ships!

The speed is sixteen knots, and the last speed is fifteen.5 knots.

It is equipped with four large-caliber rear-loading rifled guns, and adopts a double-linked yellow front and rear central axis layout.

The turret adopts a semi-enclosed open-air turret with a low freeboard design.

The use of steel surface iron armor to further improve the protection strength, while expanding the protection area.

These technical characteristics have become a consensus that has gradually reached by the navies of various countries.

Not to mention the navies of large countries, even the navies of small and medium-sized countries are also keeping up with the world trend, such as the navy of the Orr Kingdom, when they ordered the princess-class second-class battleships before, they also hesitated about the firepower layout and turret design, but after hesitating and tossing, they still chose the central axis and semi-enclosed open-air battery layout.

The warship designs of the navies of various countries in the four years of Qiansheng were basically finalized, and even the Marshal Collin-class battleships of the Krull Kingdom Navy, which were exposed in the fifth year of Qiansheng, still did not deviate from this design framework, although they used very terrifying naval guns of 350 mm and 30 times caliber.

Time has entered the seventh year of Qiansheng, just when the navies of various countries thought that the design of warships would continue according to this design concept, but the navy of the Daheng Empire chose to change!

However, the Great Heng Imperial Navy was canceled in May of the seventh year of Qiansheng, and the construction of an Endless Sea-class battleship was originally scheduled to start in July this year.

At the same time, the third phase of the development plan of the Daheng Imperial Navy was submitted to Emperor Lin Ziran.

It is not a pre-plan or a medium-term plan in the second phase of the development plan, but a new stove and a third phase of the development plan.

More importantly, the strategic thinking in the third and second phases of the development plan has changed dramatically!

In the second phase of the development plan, the core idea is to attack the navy globally, and the core tactic is to directly drive the battleship to someone else's door and implement a close blockade!

Close blockade and anti-close blockade, this is the common naval idea of the Krull Kingdom and other naval powers, as well as the navies of small and medium-sized countries.

The naval powers blocked the enemy's ports with battleships and blockaded the coast.

Countries with weak navies have tried to use coastal defense ironclad ships and coastal defense batteries to carry out defensive operations and counter-blockades.

Although the two are opposites, they actually follow the same line of thought of naval warfare.

For many years before the Great Heng Imperial Navy, it also followed this line of thought!

However, in the third phase of the development plan of the Great Heng Imperial Navy, the navy no longer mentioned a close-range blockade, but began to raise a long-distance blockade.

Even according to this shift in core thinking, a series of new warship designs were submitted!

In particular, the design scheme of the new generation of battleships, which has been debated for a long time within the navy, was directly overturned and redone, and a design scheme completely different from the main warships of the navies of contemporary countries was chosen: the high-freeboard design scheme!
