The is expected to have a tonnage of 26,000 tons, and the power system is expected to be powered by a steam turbine!

God knows why he would think of using steam turbines, the shipborne steam turbine technology of the Daheng Empire has not been developed for a few years, and it has just been tested in small shipbuilding, and it has not been successful......

According to the R&D plan, this thing can barely be used as a power for warships after five years, and if it is to be used as a power for capital ships, it will have to accumulate for a few years.

Hou Hai Shaoqing basically used the power system that was scheduled to be used in five years or even longer, and used it on the current battleship.

Because Hou Haishaoqing's design ideas were too radical and he always wanted to use advanced technology, many people in the Ship Administration Department persuaded him, saying that this time to unify the all-heavy artillery battleship, but it was about the imperial sea power, and it was not the time for you to toss and test it casually, you want to play, and you can continue to play with the cruiser Hetai in the future.

In the end, Hou Hai Shaoqing put forward a condition, let me give in and get some uncharacteristic battleship design, but you have to let me build a new cruiser, not just a paper design, you also have to build it, the navy senior management pondered, yes, who let the ship administration department can shoulder the design of the new battleship design, there are only a few designers, and the navy is not very satisfied with the design plans of several other designers, and now count on Hou Hai.

And Hou Hai just wanted a cruiser as a toy, saying that the tonnage was at most a thousand tons, and a thousand tons of toys were not worth a few dollars, let him toss it.

In this way, Hou Hai Shaoqing got a unified all-heavy artillery battleship for the navy according to the existing technical conditions.

The main gun adopts the 12-year-old 300 mm 45 times caliber main gun, which has completed preliminary research and development and will be mass-produced next year, and is equipped with a double-mounted integrated turret, which is also the main gun on the Fengshan-class battleship.

It adopts a five-seat twin installation, a total of ten main guns layout, one in the front and two in the rear, one on the side side, the side firepower can reach eight, and the front and rear firepower can reach six.

Its turret is also a relatively mature existing integrated enclosed turret, which can be loaded in all directions, with smokeless propellant and other technologies.

The rate of fire of its main gun can reach 1.5 rounds per minute.

Because the design idea of the new warship is to go to long-distance combat, especially the decisive battle of the fleet, and the pursuit is to use the main gun to kill the enemy ship at a long distance, so the elevation angle of the main gun is very large, reaching 16 degrees, and the maximum firing range can reach 18,000 kilometers.

The problem is that the Great Heng Imperial Navy does not yet have the technology to accurately hit a moving target at a distance of 18,000 meters......

This maximum effective range of 18,000 kilometers is actually a typical advanced design.

Under the combat idea of fighting at a distance, those rapid-fire guns of 150 mm caliber are useless!

Neither the range nor the power can be participated in in the decisive battle, and can only fight a dozen enemy light warships.

Considering that the role of the secondary gun was completely reduced to attacking light warships, the 150-mm rapid-fire guns with a larger caliber and lower rate of fire were also abandoned, and the 120-mm 45-caliber rapid-fire guns with a higher rate of fire were used instead, but the number was more deployed, and they were used in conjunction with the 75-mm rapid-fire guns to strengthen the striking capability of light warships.

The armor adopts the most advanced Luojing armor, the thickest armor of the main armor belt and the command tower, turret and other positions reaches 280 mm, adopts the idea of comprehensive protection, the protection area is increased, and the protection design of the torpedo is strengthened, and a special anti-mine compartment is designed.

In the Battle of Beauvois, although the torpedo boats on both sides were useless, the threat of torpedoes still existed, especially at night when the threat of torpedo boats was still huge, otherwise the two sides would not have chosen to avoid at night.

In addition, in the Battle of Bova, many warships on both sides hit mines and sank, at that time in the sea off Bova, both sides dropped a large number of mines, these mines caused a lot of trouble to the follow-up Daheng Navy, a Crane-class armored cruiser was sunk by mines and was forced to rush to the beach, and another destroyer and a cruiser were sunk, and several merchant ships were also smashed.

In other words, many of the mines that sank these warships and merchant ships were dropped by the Daheng people themselves......

In addition to mines, at the same time, the Daheng Imperial Navy itself is working on thermodynamic torpedoes......

This time, a special anti-torpedo compartment was directly added to the main battleship, which can also be used in combination with anti-mine nets to enhance the battleship's ability to defend against torpedoes and mines.

In terms of power system, it adopts the most advanced four-cylinder three-expansion steam engine, with mixed combustion water tube boiler, the maximum power can reach 23,000 horsepower, and the maximum speed is expected to reach 20 knots.

The standard displacement of the entire battleship reached 18,500 tons, and the full load displacement was expected to reach 22,000 tons.

In the first half of this year, the Fengshan-class battleships that were urgently started had a standard displacement of more than 1,000 tons.

And in terms of main gun firepower, it cannot be compared.

If it weren't for the fact that the construction of the Fengshan and Longshan was too fast because of the war, it would have been difficult to stop the construction, and perhaps the navy would have stopped the construction plan of these two new warships.

After all, these two battleships, together with the previous four Luohe-class battleships, were already obsolete when they were still under construction and not in service.

But this situation is also a normal situation, technology continues to advance, there will be huge changes in two or three years, and the construction cycle of warships is very long, so it is normal for warships to be still on the slipway but have become obsolete, and it is not only the case of the Daheng Empire, but also other countries.

After finalizing the design plan, the Navy's Ship Administration Department once again inquired about the research and development progress of various subsystem suppliers, and obtained that the main technologies of each subsystem, such as 300 mm and 45 times caliber naval guns, unified fire control, etc., patted their chests and said that the research and development must be completed according to the scheduled schedule, and the Navy can be regarded as finalizing the design plan of a new generation of unified all-heavy gun battleships.

And reported to the Emperor of the Daheng Empire, Lin Ziran, who quickly approved the construction plan of the class of ships, and preliminarily named the Ningyu-class battleships, and planned to build four ships of the same class, but the funds for this fiscal year were tight, so only two ships were built.

As for next year, let's see next year, even if it is built by then, it will definitely be an improved version with a new design.

The Ning Yu-class battleships are already similar to the dreadnought-class battleships in Lin Ziran's impression in all aspects.

That is, the power system is slightly worse, the design plan is very clear, limited by the power system, although the maximum speed can reach 20 knots, but this ultimate speed is difficult to maintain for a long time, and the jitter of the power system will be very large when the ultimate speed, which will affect the shooting accuracy of the naval gun.

However, there is no way to do this, with the current steam engine to push this kind of 20,000-ton battleship, and if you want to run twenty knots, you naturally need to pay a certain price.

This kind of defect can only be improved after the development of steam turbine technology in the future.

According to the traditional construction plan, at the same time as the construction plan of the new generation of battleships begins, the Daheng Imperial Navy will also start the design and construction plan of armored cruisers at the same time.
