Chapter 1826 Dahan Class Ironclad Ship
Dalian Bay Imperial Shipyard, which has produced generation after generation of famous steam ironclad ships for the Admiralty.

The experimental ship "General Fubo" of the main ironclad ship of the first generation of the Daqin class, the official sister ships "Weiqing" and "Huo Qubing", and dozens of ironclad cruisers and frigates.

Chu Yun came here again for no other reason. The official sister ship of the second-generation Dahan-class main ironclad ship was finally launched.

It is not technology that hinders the Imperial Shipyard from building official ships now, but the lack of demand.

In short, the five fleets of the Kyushu Army are now capable of traveling across the world, and with more cost-effective armored cruisers, they can complete tasks such as deterrence, escort, and patrol. The official ships of the second-generation steam ironclads are long overdue.

If it weren't for Chu Yun's strong advocacy that even in peacetime, even in peacetime, he still needs to develop ironclad ship technology even when he is extremely ahead, maybe the two sister ships would not be launched.In order to build these two ships, it cost 100 million taels of silver, and in the future, funds will be allocated to them for maintenance every year, and each ship will be equipped with hundreds of crew members.
In peacetime, it is better to build several smaller steamships than to maintain a capital ship.

"I imagined that China should have [-] capital ships and [-] cruisers, but if you think about it carefully, that kind of burden is too big, even if you can build it, you can't afford it."

"That's right, even an ironclad cruiser costs several 10 taels of silver, and the annual maintenance fee is tens of thousands of taels, as well as the cost of various supplies. Capital ships are even more expensive."

Chu Yun came to the Imperial Shipyard with a group of officers from the Admiralty, and they chatted as they walked.

He came here during the Liugong Island exercise a few years ago. At that time, the Imperial Shipyard built a test product of the second-generation main ironclad ship-a shallow-water heavy-gun ironclad ship with a turret.

Now, the official ship of the second-generation ironclad ship has just come out.

The director of the Imperial Shipyard rubbed his hands: "If the design of the first generation of ironclad ships is still in the age of sails, then I can guarantee that the second generation of ironclad ships, the Dahan class with a turret structure, is definitely different. vessel!"

Chu Yun and the others walked into the secret dock area of ​​the Imperial Shipyard, which was guarded by naval soldiers layer by layer, because there are the latest ships here, which have not yet been displayed in front of the world.

Chu Yun entered the secret dock more than once, and when he saw two Dahan-class sister ships parked in the dock, his eyes lit up.

The huge main gun protrudes from the turret, and the thick armor covers the hull and turret. Without sails, it relies entirely on steam power to travel!

This is the steam ironclad ship he really wanted!
"The Dahan-class ironclad ship is about 94 meters long, 18 meters wide, and has a draft of 6 meters. Its full-load displacement can reach 7500 tons, which is smaller than the Daqin-class ironclad ship. However, the structure of the Daqin-class ironclad ship is outdated. Now it seems that it uses a large number of ships. Steel is useless on the blade. The Dahan class is completely different. After the tonnage is reduced, the firepower and protection are stronger. It is unimaginable, right? The power is two horizontal three-cylinder reciprocating steam engines, and 8 circular combustion engines. The coal boiler has a power of about 6800 horsepower, a speed of 15 knots, and a range of 4500 nautical miles."

The director of the Imperial Shipyard proudly introduced the parameters of the two Dahan-class main ironclad ships to them.

This is the first capital ship to use the turret structure - "Wendi" and "Jingdi"!
Chu Yun and others boarded the ship full of praise.

The armor of the main ironclad ship of the Dahan class is so thick that it eclipses all the shells of this era.

"In order to save costs, the armor layer above the waterline is thicker, 35 centimeters, and the armor layer below the waterline is difficult to be attacked, so the armor layer is only 30 centimeters." The factory director introduced to the big customers and bosses who came to Chu Yun The armor of the Dahan-class ironclad ship.

30 cm armor, this is also called cost saving?

What level of armor is this? Small-caliber shells fall on it, and it probably doesn't feel like it at all!

Except for the armor-piercing shells equipped by the Kyushu Army itself, it is estimated that there are no other shells that can penetrate the armor of the Dahan-class ironclad ship.

Even if it is fried with black powder, it will not explode.

In other words, the two ships in front of them are invincible, and the sharpest spears and strongest shields are concentrated on the two iron-clad ships in front of them.

"There are other equipment on board to ensure the normal operation of the ship. Searchlights are already standard equipment for ironclad ships. Each ironclad ship is equipped with two searchlights, with illumination levels of 1 candles and 2 candles respectively. Three power generators are also equipped. The machine provides 3 kilowatts of electricity, which can provide lighting in the cabin." The director continued.

Equipped with a steamship equipped with searchlights, generators, and steam engines, Chu Yun found that human intelligence is more terrifying than he imagined. He used to think that steamships were commonplace, but when he personally experienced the transition from sailing wooden boats to iron-clad ships, he realized that I realized that the changes in technology have condensed the unimaginable wisdom of ship designers and workers.

The more complex the technology is, the more it relies on accumulation, and every breakthrough is based on the research of the predecessors.

The Dahan-class armored ships have already used technologies such as turrets, reciprocating steam engines, searchlights, generators, and thick armor. The complexity is not comparable to that of the original steam ships.

"In fact, the reason why the work has been delayed for a while is that there is another important reason besides the fact that there is no need to rush the work. The Imperial Arsenal originally told us that they provided 18 tons of front-loading rifled guns, but they provided us with 31.5 tons of rifled guns the year before last. Tons of breech-loading main gun! The core of the Dahan-class ironclad ship lies in the armor and turret. The main gun used has been greatly changed, and our turret and ammunition supply system have also been greatly changed, so we spent more time than imagined. Refit the ship," complained a ship engineer.

"I know about this. It's really not your shipyard's fault," Chu Yun said.

Chu Yunren has been researching breech-loading artillery for a long time, focusing on Armstrong artillery. However, the research on Armstrong artillery has been full of twists and turns, and it has not been so smooth. Bomb explosions often occur during experiments.

It was not until three years ago that Chu Yun finally started the breech-loading artillery technology and summoned a group of talents from the Krupp company to solve the problem of breech-loading artillery.

Therefore, the Krupp breech-loading main gun was temporarily required to be equipped on the Dahan-class steam ironclad ship.

The ship engineer patted the huge naval gun: "Two double-mounted turrets, a total of four 4mm breech-loading main guns, using hydraulic power. Only such artillery with armor-piercing shells can penetrate its ships. Also That is to say, it is its own artillery that can penetrate its armor. In addition, there are one 305mm breech-loading secondary guns at the bow and stern, each weighing 1 tons, to make up for the lack of fire rate of the main gun. All in all, the big man Class ironclads are invincible."
