The Turtle-class multi-purpose combat platform roams the interior of the Imperial Navy's warport, showing that it is far faster than other surface ships, and then beginning to show its agile maneuverability. The hovercraft lowered its speed to 40 knots and began to make a sharp turn, and the entire hull tilted at a large angle, as if it was about to turn over......

This kind of large-angle sharp turn is difficult to achieve on ordinary warships, because the sides of the hull have to withstand extreme water pressure when turning, which can easily cause the hull structure to be damaged or directly broken. Therefore, at the beginning of the design, the ship designers limited the maximum steering angle of the universal ship.

And water pressure is not a danger for hovercraft.

The Turtle-class multi-purpose combat platform made a sharp turn of 180 at an incredible speed, and then began to accelerate towards a shoal in the military harbor.

With such speed and maneuverability, in a naval battle at a regular distance, it is really a matter of luck to hit it. However, once it is seized by the turtle-class multi-functional combat platform, it uses the speed to break through and release the torpedo at close range...... If you can sink a battleship, even if it is sunk, it will be profitable.

The Marquis of Whitehead and Field Marshal Hopkin had been shocked by the performance of the Turtle class, and their impression of the battleship had changed upside down.

This is the kind of ship that the Imperial Navy needs, its speed and maneuverability that can make it ignore its defensive weaknesses. It can perform multiple functions at the same time, and it is extremely suitable for the current Flamenck Navy.

Field Marshal Hopkin was already imagining what caliber of cannon he could put on this battleship.

And at this time, Rookes also realized the crisis, this battleship that broke the traditional way of thinking, not to talk about what level of its final combat effectiveness is, but now look at ...... It obscured all its weaknesses with its speed alone.

However, Rooks will never admit defeat easily, he can't see such a large order slip out of his palm without his eyes.

"Your Excellency the Governor, Your Excellency the Marshal. The performance of the Turtle-class multi-functional combat platform brought by Blackfire was indeed beyond everyone's expectations, and it can be said that it created a new ship design system.

But there is one thing I need to be reminded of.

The principle of the Turtle-class battleship is to use steam to create a strong air pressure between the bottom of the ship and the surface of the water, and this air pressure can hold the entire battleship above the water. It is not affected by water resistance in order to exhibit such high speeds.

However, the turtle class is not subject to water resistance, nor does it enjoy the benefits of buoyancy.

Before the formation of air pressure, the turtle class sails very slowly. And after the formation of air pressure, it takes a lot of energy and water to hold up such a heavy battleship. According to my experience estimates, the Turtle-class consumes three to five times more energy and water than the Sailfish-class corvettes.

This means that the cruising range and load of the Turtle-class multi-functional combat platform are very small, and it is not suitable for long-distance ocean voyages, nor can it perform high-intensity maritime combat missions. ”

Cruising range and load are both important indicators of a warship.

A warship with its hull lifted out of the water is certainly more energy-intensive than a warship floating in the water. If a battleship can't go far, its combat value will definitely be greatly reduced; If too much load is taken up in order to hold more energy and water, then the lack of weapons and ammunition will also put a warship in an embarrassing state.

Marshal Hopkin said: "Mr. Rookes is worthy of being an expert in the shipbuilding industry, and he can see at a glance the advantages and disadvantages of the Turtle-class multifunctional combat platform. However, for the current Frominck Navy, the immediate priority is to quickly build up an offshore defense fleet.

The short range of the Turtle class is acceptable.

Of course...... The Sailfish-class corvettes are also very good, and the Imperial Navy will definitely not miss this good frigate.

I think other torpedo boats, minesweepers, minelayerers...... These too complex warship models do not need to be considered, and the Turtle-class multifunctional combat platform can fully assume their combat functions.

And then the corvette ...... The Sailfish class of the Rookes shipyard was chosen, so that our fleet would have a certain ability to fight in the open sea.

Sailfish-class corvettes in the open sea.

Turtle-class multi-functional combat platform for offshore use.

Coupled with the security artillery, when we face an invasion from the sea, we can organize three lines of defense.

What do you think? Your Excellency the Governor. ”

The Marquis of Whitehead did not immediately agree, but asked Da Liang, "Young Master Liang, does the Black Fire Company's turtle-level multi-functional combat platform have any other advantages?" ”

Da Liang replied, "Of course there is...... The Turtle-class multi-functional combat platform can reach a cruising range of 3,450 nautical miles at an economic speed of 35 knots.

In addition, the current Turtle class only has a hull and power system, and the empty weight is 954 tons without any armament, and the full load weight is 1847 tons.

The cruising range was tested at full load. ”

"It can't be!" After hearing Da Liang reveal the range of the Turtle-level multi-functional combat platform, Rookes immediately shouted: "Even if you use all the loading weight to hold magic energy ore and water, your ship will not be able to last 3,450 nautical miles." It has to hold more than a thousand tons of dead weight, how can it be farther than my sailfish-class range? ”

Da Liang smiled: "That's because the turtle-level multi-functional combat platform doesn't need to be filled with water. Our latest steam engine can directly convert seawater that comes into contact with the bottom of the ship into steam. Without pipes and spouts, there is no excess energy loss.

Therefore, although the Turtle-class multi-functional combat platform consumes more energy than a conventional warship, it certainly does not consume as much as Mr. Rookes described.

In addition, the turtle class does not need to carry a large amount of pure water when sailing, which once again improves the interior space and reduces its own weight. ”

Rookes froze.

Directly turn seawater into steam...... How is this possible! Today's steam engines vaporize water instantaneously in a cylinder, but the sea surface is open, and turning seawater into steam is not a simple heating.

How did Blackfire do it?

Marshal Hopkin didn't care about this technical problem, he only saw that the Turtle-class multi-purpose combat platform could run farther and be equipped more than the Sailfish-class corvette. So...... If there is a simple and high-performance warship that can undertake combat missions in the open sea, why choose a frigate that is slow, less equipped and so complex?

The Flamenck Empire's sea power needs to be a turtle-level multi-functional combat platform.

But when Marshal Hopkin was about to announce the official purchase of the warships provided by the Black Fire Company, a sudden chaos broke out at the military port.

For some reason, the Turtle-class multifunctional combat platform that was returning to the coast did not reduce to a suitable landing speed when approaching the coast. It rushed towards a shoal, and the massive hull rushed headlong onto the gravel beach with a loud roar......

What happened?

Is it out of control!
