Qingying sorted out her thoughts and said unhurriedly: "At present, the number of armored cruisers in the arrays of various naval powers is not a few, and it is developing in the direction of large-scale and heavy firepower; If Germany were to simply trot and catch up, it would take a lot of time and money, which is obviously not the best idea. Therefore, the new high-speed ships built by Germany must have the strength to completely crush these patrols; And all the existing or slipway patrols of the countries of the world will be desperately surpassed by our German warships in terms of firepower, protection, and speed! Only in this way will we be able to regain our current disadvantage in the fast fleet in one fell swoop. ”

"Desperate over? So how do you do it? William couldn't help but ask.

"According to the conclusion of the wargames, if a warship is to effectively catch up with its opponent, it should be at least 2 knots higher than its opponent. At present, the speed of the patrol is between 22 and 23 knots, and for the sake of conservatism, the speed of the new ship should not be lower than 25 knots. Qingying said without blushing and without a heartbeat.

"Verse 25!" Tirpitz's hand holding the coffee cup stopped in mid-air, a look of disbelief on his face. What are you kidding, the speed of ordinary battleships is only about 18 knots now, and the fastest armored cruisers can only reach 23 knots in the best condition; And just the increase in speed of these 2 knots, the output power will be increased by almost 50%! If another person had popped up this number with a mouth cannon, Tirpitz would have roared in anger long ago; However, he knew that Dao Qingying had attainments and foresight in the design of warships that were difficult for ordinary people to achieve, and it was impossible to fabricate this matter. Moreover, almost all the decisions made by this young man in the naval field before were proven to be the right ones after the fact. In light of this, after hearing this astronomical figure, Tirpitz did not rush to express his opinion, but quietly waited for what he was going to say next.

Qingying said: "In terms of firepower, 6 11-inch guns are actually barely enough; After all, the rate of fire of this gun can reach 2.5 rounds per minute, and the 11-inch shells equipped with the cap can easily penetrate the enemy's 6-inch armor. However, compared with 6 main guns, the density of blows caused by 8 guns can obviously make people feel trustworthy and reassuring, so the new fast battleship should have the outstanding firepower of 4 twin 11-inch L47 main guns, so that it is as easy to destroy the enemy's patrol as slaughtering a pig and slaughtering a dog. Of course, in order to reduce weight, the addition of a fourth main turret does not have to be carried on the bow, but can be placed in the middle of the hull. ”

"8 11-inch guns, 25 knots?" William muttered about the two data, bowing his head and groaning.

"As for protection, the ship's main armament is a 5.2-meter-high 250 mm armor, and the horizontal armor needs to be thickened to the same extent as our new battleships. This is because once the main armor is penetrated by enemy battleship-level shells, its fragmented shrapnel requires 70 mm thick main horizontal armor to be able to resist relatively safely; Although the dome armor has a coal seam on it as a buffer, it should not be thinner than 50 mm. Otherwise, if shrapnel is allowed to fly into the core compartment, the speed will be damaged at least, and the ammunition depot will be detonated at worst, and the entire battleship will be finished! This is also the reason why the total thickness of the two-layer horizontal armor of our class of Prussian ships is still 90 mm, despite the fact that the distance of the current naval battle is only 4 or 5 kilometers. Horizontal armor of this thickness is not intended for protection against shells at all, but for shrapnel. Qingying added. In the historical Battle of Jutland, the horizontal armor of the main ships of both sides was repeatedly pierced by shrapnel from artillery shells that penetrated the main armor, causing serious damage. The Americans thought that 64 mm thick horizontal armor would be sufficient, so the main horizontal armor of the standard Iron Tortoise was of this thickness; The British, on the other hand, believed that 75 mm was needed to effectively withstand the penetration of shrapnel. Since the British had actual combat experience, Qingying was more inclined to the British conclusion.

Hearing this, Tirpitz finally couldn't stand it anymore. His eyes gradually narrowed, and he said in a tone full of disbelief and anger, "Your Highness, do you know what kind of ship this is? The firepower of 8 doors and 11 inches and the speed of 25 knots alone are already extremely difficult indicators to achieve; Now you still demand its 5.2-meter-high 10-inch main armor and horizontal armor that reaches a total thickness of 90 mm? If you put it on the drawings, the standard displacement without fuel is at least 20,000 tons, and the cost will exceed 40 million marks! This one-sided pursuit of tall and complete design not only commits 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 know the essentials of ship design, how could you not even think of this? ”

Seeing Tirpitz's displeasure, even William shook his head, Qingying suddenly chuckled. He waved his hand slightly, and said hesitantly, "What General Alfred said is not accurate. If the conventional design is followed, a scale of 20,000 tons is indeed required to achieve these properties; But General, have you forgotten who I am? Since I dare to propose such a battleship with the all-round development of the three elements, then there must be a way to control the tonnage and cost; This was the case with the first decisive battle loadout, and the same is true for the perfect high-speed battleships now! ”

"But Etter, the reason why the original decisive battle was successful was because it didn't have a lot of speed increase, but now you can increase the speed from 20 knots to 25 knots, and double the output is not enough!" William's mind raced, and he instantly pointed out the real reason, "The 3.2-meter fully loaded aft freeboard is already the minimum and can no longer be compressed; And your requirements for the main armor belt and horizontal armor are so high, I really can't think of any other way to reduce the tonnage. ”

"Quite simply, we can use underwater protrusions." Qingying's thin lips opened lightly, and she said word by word.

"In order to effectively defend against secondary shrapnel damage caused by the penetration of the main armor, the thickness of the main deck must be 70 mm, and the average total thickness of the two decks is 90 mm; This thickness was already twice the thickness of the deck of the previous battleship, which consumed a lot of armor weight. So, if we want to reduce the tonnage, then we have to think about how we can reduce the deck area. ”

Qingying hastily drew a schematic diagram, and then pushed it in front of William and Tirpitz: "Since this is a high-speed ship, a long hull is needed to ensure a high-speed ship type; Taking into account the volume of the ship occupied by the high-power power, the length of the battleship cannot be compressed. Therefore, the only thing that can be done is the width of the boat. If the width of the ship can be effectively reduced, then the deck defense area can be reduced, the ship type can be reduced, and the tonnage can be reduced. ”

Tirpitz was puzzled, and said, "But as soon as the ship's width decreases, what will the ship use to drain enough water to maintain its freeboard?" In addition, since the width of the core compartment is fixed, the reduction of the ship's width will inevitably lead to insufficient underwater mine protection depth, and its anti-torpedo capability will also be greatly damaged. ”

"That's why we have to introduce underwater protrusions!" Qingying smiled slightly, and pointed her slender finger up the schematic diagram, "For example, the width of a boat was originally 26 meters, then we can reduce it to 22 meters, and then add 2 meters of protrusions on each side of the water to compensate." As a result, the width of the underwater part of the battleship has not changed in any way, and the freeboard and mine protection capabilities have been effectively guaranteed; On the other hand, the main deck on the water has been reduced due to the narrowing of the ship's width, which saves a lot of armor weight. In addition, this measure can also reduce the size of the ship, reduce the resistance of the traveling wave, and also reduce the area of the nose and tail lateral armor, and the tonnage and cost of the battleship will be greatly reduced. ”

"Good way......" William muttered; After a while, he suddenly slapped the desk hard, and his eyes lit up and he said loudly, "What a way!" Ettel, how did you guys come up with this? ”

Qingying smiled and said, "If you want to build a frantic battleship, how can you take the ordinary path?" Actually, I got inspiration from the Brandenburg-class battleships that we built 15 years ago. The French inclined hull was not worth the cost, but it could greatly reduce the deck area, so I took it a step further and created this underwater protrusion. I have already calculated that if this is done, 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. And once this kind of warship is built, it can not only form a one-sided slaughter of all the patrols in the world, but also join the battle line—praise God, isn't this as graceful and perfect as a cat? ”

At this moment, Tirpitz also reacted, and said slowly: "Not bad. This not only cut the deck area, but also reduced the size of the ship; Under the action of two phases, the displacement can indeed be greatly reduced. Since the ship's main guns are all arranged along the central axis, the deck width requirements are not high, and the impact of this is extremely limited. Speaking of this, there was a hint of surprise on his face, but more of an excited look: "Thank you, Your Highness." I'll ask the designers to change the design according to His Highness's wishes tomorrow, and I believe that it won't be long before this paradox-type battleship will appear in front of the Shilu interface! ”

While they were talking, there was a sudden knock on the door; William's brow furrowed slightly, and he spat out a syllable that allowed him to enter. When he saw the red wallet under the guard's armpit, the pupils in his eyes couldn't help but shrink.

(Yesterday, the author typed a few words, and the German overcalculated artillery double diameter is the tail of the cannon behind the medicine room, and I also thank the book friend Qing Ge Miao Wu Mulan Boat for the reward~~)
