Because compared with the King-class battleships announced by the Navy of the Krull Kingdom, the Yonglin-class battleships that are still under construction on their side can compete in firepower, but they are at a huge disadvantage in terms of armor protection and power speed.

As for the high probability of existence, not to mention the new generation of capital ships of the Krull Kingdom that use three-hundred-and-fifty mm caliber naval guns, the large-caliber main guns alone are scary enough.

The performance is estimated to kill all the warships in service and under construction or even on the drawings in the world!

In the face of such huge pressure, there was naturally a call within the Daheng Imperial Navy to build capital ships with larger tonnage and larger caliber naval guns.

But the Daheng Empire not to mention more advanced naval guns, even the 300 mm and 30 times the caliber of the naval guns were barely managed with the strength of the whole country, and it was impossible to want a larger caliber naval guns in a short time.

Therefore, the Daheng Navy can still only build warships equipped with 300 mm and 30 times the caliber.

As for why a large number of warships that seem to be backward are still being built, it is because even if the performance of the Yonglin-class follow-up improved battleships is a little backward, it does not mean that they are useless.

No matter how advanced the warships of the Krull Kingdom are, they also have the limitations of the times, and they are supported by 350 mm caliber breech-loading guns, steel-faced ironclad ships, and three-expansion steam engines with strong ventilation technology and higher air pressure.

However, even if the other side has a comprehensive advantage in firepower, protection and power through stronger industrial technology capabilities, it is still impossible to be one-sided.

The Yonglin-class naval guns of 300 mm and 30 times the caliber are powerful enough to threaten any warship in service, including the King-class battleships of the Krull Kingdom, and even their secret new warships are estimated to be unable to stop them.

If the opponent's armor is too thick, then it is a big deal to get close to fight.

This is also the reason why many years of countries have chosen to build shore defense ironclad ships or second-class ironclad ships with smaller tonnage.

As for the performance gap, what to do?

According to the consistent idea of Daheng people, the performance is insufficient and the number is made up!

Originally, it was planned to build two improved battleships of the Yonglin class, but the Navy has changed its plan, and two is not enough, so it has to build four.

The idea of the Navy is simple and simple!

Lin Ziran didn't say much about this, anyway, in the early stage of the second phase of the naval plan, there were eight battleship plans, according to the previous plan, in addition to the existing two unification-class battleships, two ships were started in the second year of Qiansheng, three ships in the third year of Qiansheng, and three ships in the fourth year of Qiansheng, making up a total of eight ships.

However, Qiansheng has not started construction of any ship for three years, and it has not started construction for the time being this year.

So it's normal to make up for it later.

Anyway, the funds have already been booked, and since the navy has made a decision, let's start construction!

Soon after, the navy's shipbuilding plan was approved, and it is expected that two ships will start construction in the second half of the fourth year of Qiansheng, and two more in the first half of next year, making a total of four new-type battleships.

The lead ship of the new battleship is the Endless Sea, also known as the Endless Sea-class battleship.

The Endless Sea-class battleship is a mature and improved version of the Yonglin-class battleship, with a standard displacement of 10,500 tons, and the Yonglin-class battleship belongs to the same low-freeboard semi-enclosed open gun design, equipped with a double-mounted 300 mm 30 times caliber main gun at the front and rear of the central axis, with six 150 mm 30 times secondary guns and multiple 75 mm and 40 mm small-caliber secondary guns.

Its main armor belt is made of steel-faced iron armor, which reaches 380 mm at its thickest point, 300 mm at the thickest point of the gun mount armor, and 300 mm at the thickest point of the conning tower.

A new type of steam engine was used, with a power of 7,500 horsepower and a speed of 15.5 knots.

The design of the Endless Sea battleship is also a typical design scheme for the capital ships of the Daheng Imperial Navy in recent years, using the central axis front and rear double-mounted large-caliber main guns, semi-enclosed open battery low freeboard design, although this design has poor seaworthiness in complex sea conditions, but in the case of the main gun is becoming more and more powerful, and at the same time, even the steel surface iron armor is difficult to resist the main gun, in order to ensure the protective performance, the armor must be very thick, which also leads to the inability to take a fully enclosed turret, and the center of gravity can not be made too high, But also need to control the tonnage, control the cost.

In this way, the low freeboard design became the inevitable choice of designers in the early years of the Daheng Imperial Navy.

Interestingly, the King-class battleships of the Krull Kingdom Navy also used a low-freeboard semi-enclosed open-air turret design.

Of course, the navy of the Krull Kingdom is not a copy of the battleship design of the Daheng Navy, and people play this design much earlier than the Daheng Navy.

If you have to be more serious, it is actually the battleship designers of the Daheng Navy who borrowed a little from the design of the Navy of the Krull Kingdom.

What's that, the battleship can't be said to be plagiarized, just borrowed!

In general, the Endless Sea-class battleships and Yonglin-class battleships have not changed much, the details have changed, and the biggest change is the change in armor, which also represents the rapid technological change on the Blue Star in recent years.

In just a few years, the armor of the warships of various powers has changed from wrought iron armor to steel-faced iron armor.

Luohai Iron and Steel Plant according to foreign samples of this kind of armor, after three or four years of technical research, successfully copied and produced this kind of armor, although this kind of armor is more expensive, but the protective performance is much better than wrought iron, after live ammunition test, 300 mm of steel iron armor can obtain 400 mm of wrought iron armor of protective effectiveness.

This allows the ship to reduce the weight of the armor per unit area, allowing the armor belt to be laid over a larger or thicker area, and freeing up weight for more secondary gun fire or an increase in the power system.

Although the barrel length of the caliber of the attached gun has not changed, the barrel life is longer, and at the same time, the bore pressure is better, and it can even be fired with a strong charge.

In terms of power, the three-expansion steam engine is still used, but the processing technology of the steam engine is better, which makes the power of the steam engine improved, and when the maximum power is turned on, the bearing time is longer, and it has barely reached the average level of the steam engine of various powers.

In addition, it will also be equipped with a new four-year armor-piercing bullet, which is an armor-piercing bullet product developed by the Jingzhou Machinery Bureau, well, it is said to be a research and development, but in fact it is a pointed-nosed armor-piercing bullet copied from the Krull Kingdom.

The warhead is made of hardened high-strength steel, and the tail of the projectile has a cavity and is loaded with explosives, which uses strong kinetic energy to penetrate the armor of enemy warships and explode to kill enemy soldiers.

And according to the different internal charges, they are divided into armor-piercing shells and semi-armor-piercing shells!

Although the Endless Sea-class battleships that adopt a series of new technologies do not seem to be much different from the Yonglin-class battleships on the surface, and even have similar tonnage, the performance gap between the two sides is actually relatively large.

To a certain extent, the Endless Sea-class battleships are actually going to the Navy of the Krull Kingdom, especially the steel-faced ironclad technology, which is actually not very mature, and the cost is also very expensive.

But in order to fight against the King-class battleships, even if the technology is immature and the cost is expensive, the navy is gritting its teeth.
