Qingying sorted out his thoughts and said slowly: "At present, the number of armored cruisers in the array of powerful naval powers is not a small number, and it is developing towards large-scale and heavy firepower; if I, Germany, just rushing and chasing, then there will be no small number of time and capital expenditures, which is obviously not the best idea. Therefore, the newly built high-speed ships of Germany must have the strong strength to completely crush these aircraft patrols; and all aircraft patrols in the world or on the ship platform must be desperately surpassed by my German warships in despair! Only in this way can we recover the current disadvantages in the fast fleet in one fell swoop."

"There is more despair than? What should I do?" William couldn't help asking.

"According to the conclusions drawn from wargame deduction, if a warship wants to effectively catch up with its opponent, the speed of this ship should be at least 2 knots higher than its opponent. Currently, the speed of the equipped patrol is between 22 and 23 knots. To be conservative, the speed of the new ship should not be lower than 25 knots." Qingying said without blushing and heartbroken.

"25 knots!" Tirpitz's hand holding the coffee cup stopped in mid-air, with an unbelievable look on his face. What a joke, the speed of ordinary battleships is only about 18 knots, and the fastest armored cruiser can only reach 23 knots under the best conditions of the ship; and the output power of these two knots alone will almost be increased by 50%! If someone else had used his mouth gun to pop out this number, Tirpitz would have roared angrily; however, he knew that Qingying had attainments and forward-looking in the design of warships that ordinary people could not achieve, and it was impossible for him to fabricate it randomly. Moreover, almost all the decisions made by this young man in the naval field were proved to be the right choice afterwards. In view of this, after hearing this astronomical figure, Tirpitz did not rush to express his opinion, but quietly waited for what he would like to say next.

Qingying said: "In terms of firepower, 6 11-inch cannons are actually barely enough; after all, the fire rate of this cannon can reach 2.5 rounds per minute, and the 11-inch shell equipped with capped can easily penetrate the enemy's 6-inch armor. However, compared with the 6 main guns, the strike density caused by the 8 main guns is obviously only trustworthy and reassuring. Therefore, the new fast warship should have the outstanding firepower of 4 dual-equipped 11-inch L47 main guns. In this way, it is as easy to destroy the enemy's mount patrol as slaughtering a pig. Of course, in order to reduce the weight, the added fourth main turret does not have to be carried on the bow of the ship, but is placed in the middle of the hull."

"8 11-inch main guns, 25 knots of speed?" William murmured these two data, and pondered.

"As for protection, since it is necessary to go to the battle line, the main equipment of this ship is a whole 5.2-meter-high 250mm armor, and the horizontal armor also needs to be thickened to the same level as our new battleship. This is because once the main equipment is penetrated by an enemy battleship-level shell, its broken shrapnel needs 70mm thick main horizontal armor to resist more securely; although the dome armor has the coal seam on it as a buffer, it should not be thinner than 50mm. Otherwise, if the shrapnel is allowed to fly into the core compartment, the speed will be damaged at the least, and the ammunition depot will be detonated at the worst, and the entire battleship will be done! This is also the same as the combat distance of the current naval battle is only 4,5 kilometers, we

The total thickness of the two layers of horizontal armor of that class Prussian ship still reached 90 mm. This thickness of horizontal armor is not to prevent shells, but is used for bulletproof sheets." Qingying added. In the historical battle of Jutland, the horizontal armor of the main ships of both sides was repeatedly penetrated by shells that penetrated the main armor twice, causing serious damage. The Americans believed that 64 mm thick horizontal armor could resist, so the main horizontal armor of the standard iron turtle was of this thickness; while the British believed that 75 mm was needed to effectively resist the penetration of shrapnel. Because the British had practical experience, Qingying was more inclined to the British conclusion.

Hearing this, Tirpitz finally couldn't stand it. His eyes gradually narrowed into a slit and said in an unbelievable and angry tone: "Your Highness, do you know what kind of ship this is? The 8-door 11-inch firepower and 25 knots are already extremely difficult to achieve; now you still require its 5.2-meter-high 10-inch main equipment and a total of 90 mm thick horizontal armor? If you put it on the drawings, the standard displacement of its unloaded fuel will be at least 20,000 tons, and the cost will exceed 40 million marks! This one-sided pursuit of high-end design not only violates the taboo of balancing the cost, but its tonnage of more than 20,000 tons is also an extremely severe test for the shipbuilding industry of the German Empire! Your Highness, you are well aware of the key points of ship design, how could you not even think of this?"

Seeing Tirpitz's face unhappy, even William shook his head, Qingying suddenly laughed softly. He waved his hand slightly and said, "General Alfred's words are not accurate. If it is designed according to the conventional method, it would indeed take 20,000 tons to achieve these performances; but General, have you forgotten who I am? Since I dared to propose this kind of warship with comprehensive development of three elements, then there must be a way to control the tonnage and cost; this is the case with the first generation of decisive battleships, and the same is true for the current perfect high-speed battleship!"

"But Etel's final battle armor patrol was successful because its speed increase quota was not large, but now you jumped from 20 knots to 25 knots, and the output power was not enough!" William's thoughts turned sharply and instantly pointed out the real reason, "The 3.2-meter full-load tail freeboard is already the lowest limit and cannot be compressed anymore; and your requirements for the main armor belt and horizontal armor are so high that I really can't think of any way to reduce the tonnage."

"It's very simple, we can use the underwater protrusion." Qingying said with a pause.

"In order to effectively defend against secondary shrapnel damage caused by the main armor being penetrated, the thickness of the main deck must be 70 mm, and the average total thickness of the two decks reaches 90 mm; this thickness is already twice the thickness of the previous battleship's deck, and consumes a lot of armor weight. Therefore, if we want to reduce the tonnage, then we have to think about how to reduce the area of ​​the deck."

Qingying drew a schematic diagram and then pushed it to William and Tirpitz: "Since this is a high-speed ship, it requires a longer hull to ensure the high-speed ship type; and considering the volume inside the ship occupied by high-power power, the length of the warship cannot be compressed. Therefore, the only thing that can be done is the width of the ship. If the ship width can be effectively reduced, it can reduce the deck defense area, reduce the ship type, and thus reduce the tonnage."

Tirpitz was very puzzled and said, "However, once the ship's width is reduced, what will this ship use to drain enough water to maintain its freeboard? In addition, since the width of the core compartment is certain, the reduction in the ship's width will inevitably lead to insufficient underwater lightning protection depth, and its torpedo resistance will also be greatly damaged."

"That's why we need to introduce underwater protrusions!" Qingying smiled slightly and pointed a little at the schematic diagram. "For example, the width of a ship was originally 26 meters, so we can reduce it to 22 meters, and then install 2 meters of protrusions on both sides of the water as compensation. In this way, the width of the underwater part of the battleship has not changed at all, and the freeboard and lightning protection capabilities have been effectively guaranteed; while the main deck on the water has narrowed the area due to the narrowing of the ship's width, thus saving a lot of armor weight. In addition, this measure can also reduce the ship's size and reduce the traveling wave resistance. The area of ​​the head and tail lateral armor has also been reduced, and the tonnage and cost of the warship will be greatly reduced."

"Good solution..." William murmured; after a moment, he suddenly slapped the desk heavily, and his eyes shone loudly, "Good solution! Etel, how did you guy think of this?"

Qingying smiled and said, "How can I take the ordinary path if I want to build a crazy battleship? In fact, I got inspiration from the Brandenburg-class battleship we built 15 years ago. Although the French tilted hull is not worth the effort, it can greatly reduce the area of ​​the deck, so I went further and created this underwater protrusion. I have calculated that if I do this, the standard displacement of the ship should not exceed 18,500 tons, which is only 2,000 tons larger than our new battleship, and the cost can be controlled at about 36 million marks. Once this kind of warship is built, it can not only form a unilateral slaughter of all the world's patrols, but also join the battle line - praising God, isn't this as elegant and perfect as a cat?"

At this moment, Tirpitz also reacted and said slowly: "Yes. This move not only cut off the deck area, but also reduced the ship type; under the action of the two phases, the displacement can indeed be greatly reduced. Since the main guns of the ship are all arranged along the central axis and the width of the deck is not high, the impact of doing so is extremely limited." At this point, a hint of embarrassment appeared on his face, but more of it was an excited look: "Thank you, Your Highness. I will ask the designers to change the design according to Your Highness's wishes tomorrow. I believe that this paradoxical warship will appear in front of the world in the future!"

While talking, a sudden and rapid knock on the door suddenly sounded; William frowned slightly and spit out a syllable that allowed entry. When he saw the red wallet under the guard's armpit, his pupils in his eyes couldn't help but shrink.
