The benefits of hovercraft are obvious. It can be suspended on the surface of the sea, and with less fluid resistance, it can reach speeds far beyond ordinary surface ships.

Also because there is no need to think too much about the influence of fluid resistance, the hovercraft can be designed in a flat direction, making it more stable in wind and waves than traditional ships.

Reduced design difficulty. When traditional warships need to balance the hull with weight because of the width of the hull, and need to be careful about every space, the air cushion warship is much more generous to the designer.

Its high fault tolerance rate is very suitable for ship designers of this level of Daliang.

In addition, the air-cushion warship is fast and suspended above the sea, and the torpedo and most of the mines are not dangerous to the air-cushion warship. In addition, the air cushion warship has low noise when sailing, and the hull is low and easy to hide. It is very difficult for submarines to detect it, and even if it does...... For this type of warship, you can only stare dryly.

Therefore, air-cushion warships can be competent for multiple tasks such as anti-submarine, demining, reconnaissance, and sneak attack, which are precisely the functions of corvettes.

Finally, the air cushion warship has another advantage that all warships do not have, that is, it can conduct landing operations. After filling with pure water, the air-cushion battleship can be driven directly onto flat land. A thousand-ton warship, whether used as a firepower platform or to transport combat units, is enough to turn the tide of a local war.

In this tonnage, the air cushion warship surpasses the traditional warships of the same class in all indicators, and the only disadvantage is probably that its deck area is larger than that of traditional corvettes, and it is easy to be hit by straddle shots. But corvettes mainly rely on speed to eat, and the many points of the air cushion battleship are enough to make people ignore this disadvantage.

After determining the power of the new corvette he wanted to design, Da Liang began to draw the design of the battleship on the drawings.

Keel laying.

Then there is the watertight cabin...... When sailing and fighting, it does not touch the surface of the water, and the complex design of the watertight cabin is omitted.

The bottom of the boat is surrounded by a rubber skirt to seal the steam......

The forward propulsion system is used...... The propellers on the airship can be ordered directly with the corresponding airship manufacturer.

Then there are the various functional cabins, which are then sealed to the deck.

Weapons modules above the deck?

At this time, Da Liang suddenly realized that he didn't know what weapons the empire had suitable for carrying on this corvette. So...... The deck is empty, anyway, there is enough space on the upper floor, and when the time comes, according to the needs of the empire, you can pack whatever you want.

Pipeline laying?

There are no weapon systems, and the corresponding pipelines certainly do not need to be laid. Anyway, the interior space is also very sufficient, so get the power system right first and let the boat move. The rest ...... Wait until you're sure you need the equipment on deck and inside the hull, and then get it.

So Da Liang, who had a limited level, really designed a "battleship" with an engine and a hull as the Marquis of Whitehead and Anne had expected.

Fortunately, a simple hull designed at the bright design level can still be relied on, at least there is no need to worry about water ingress.

It took Da Liang an afternoon to design this thousand-ton corvette ship. This is probably the shortest design time in the history of warship design in the world.

All that remains is how to build it, the Blackfire shipyard has not yet been built.

It's hard to shine.

There is no shipyard, it is built in a steel plant, and there are not many things anyway, and the hull is simple and does not have much technical content. After the steelmaking blast furnace produces steel, it can be directly forged and plasticized according to the size of the corresponding hull components, and then assembled the keel and welded to the hull.

Simplicity and crudence do not require a shipwright, and a steelworker can do it.

Someone sent the design drawings of the corvette to the steel factory for people to manufacture as soon as possible, and Da Liang looked through the information of the world's ironclad ships.

Corvettes can be designed with air cushion power, but no matter how large a warship is, it can no longer follow this idea of taking the sword to the edge. Not only because the current air cushion engine is not yet able to support large warships of several thousand tons, or 10,000 tons, but also because large warships have begun to pay attention to defense and firepower.

The hovercraft is suspended on the water, and while reducing the water resistance, it is also not possible to use the water to absorb the reaction force generated by the launch of heavy artillery. The decisive battle at sea still relies on strong ships and sharp guns.

Corvettes are nothing more than a stepping stone for Da Liang to get involved in the shipbuilding industry. If you have a good battleship design, you can attract the attention of excellent ship designers, so as to invite excellent ship designers to your own shipyard. Being able to get an order from the Flamenke Imperial Navy can establish the credibility of the Black Fire Shipyard, and the battleships designed by the Black Fire Shipyard will be able to attract more attention in the future.

In order to create a combat platform for space operations, the Great Tomb must first understand the functions and design of surface ships.

At this time, the Great Tomb had collected a lot of ship design data, most of which were stolen from some well-known shipyards. Among them were many battleships in service, and there were also some battleship ideas that were still on the drawings.

Each battleship drawing is much more complex than the corvette that Da Liang has just designed. In addition to the main drawing, there are also detailed drawings of the design of each cabin and module. These are all valuable treasures, and throwing out any of them can lead to a war.

What Da Liang is doing now is to supplement his knowledge of ship design, and then complete the design of a space battle platform based on the magic alchemy technology that will appear in the Great Tomb and in the future.

This is a weapon for his own use, and Da Liang does not dare to play like designing a corvette.

Every detail must be taken with care. When Da Liang retreated to learn about battleship design. According to the steelmaking technology provided by the Scarab Company, the Rookes Iron and Steel Plant has completed the transformation of steelmaking equipment, and the special materials needed for special steel alloys have also been secretly purchased.

In the steelmaking blast furnace workshop, which is built specifically for the production of special steels, magic detection devices monitor every corner of the workshop. All the workers working here were hand-picked by Rux Clues, and he couldn't let anyone know the secrets here.
