"The main reason why our aircraft carriers are far more defended than the ones that the Americans are building is that our aircraft carriers have armored decks that can keep hangars and part of the flight deck safe. But I think everyone understands that our aircraft carrier cannot cover its entire deck with heavy armor, otherwise it will really become a battleship that will never be sunk. Yan Boxun said with a smile.

The British didn't react at first, and they didn't know what Yan Boxun meant by saying this. "Because he will sink himself when he goes into the water because the center of gravity is too high and the weight is too large!" Yan Boxun's last sentence caused the whole venue to burst into laughter, and an interesting joke enlivened the somewhat dull atmosphere.

"The area protected by the armored deck of the aircraft carrier can only be the upper part of the hangar, and the elevator connecting the hangar, our hangar is 170 meters long, plus the length of the entire armored deck of the head and tail elevators reaches 200 meters, which is probably the longest horizontal armor in the world so far, right? I remember that the length of your country's Queen Elizabeth-class fast battleships is less than 200 meters, right? And if we put another elevator in the middle, then this armor plate will be longer. Yan Boxun paused.

"Of course, you may say that the British Empire will not spare money when building a sword at sea, and it doesn't matter if the armor belt is longer, so let's talk about what kind of hidden danger if an elevator is placed in the middle." Yan Boxun said and took out a sketch. The length of some of the decks and the decks of two carriers with three and two lifts are indicated.

"Everyone knows that the internal equipment of a battleship can sometimes be incapacitated by shock and vibration when the shells are not penetrated. For example, if the cannon ring is stuck. Similarly, aircraft carrier elevators face this problem, and because of the more complex structure, there is a greater possibility of incapacitation in the face of bombs, which cannot be completely avoided even if we add armor to the elevators. So we can look at this picture and talk about what it would be like if it was bombed. What can be the difference between a two-lift carrier and a three-lift carrier. ”

"If one of the elevators in the twin lift carrier is attacked and disabled, it will not completely destroy our ability to fly, because no matter which lift is destroyed, we have a runway of more than 200 meters to continue to take off and land aircraft, and even take off heavy aircraft. And if the elevator in the middle of the three-lift aircraft carrier were destroyed, the entire aircraft carrier deck would be divided into two sections of almost equal length. The length of each section is about 130 meters, so tell me, what can you do with this distance? Is it a take-off plane or a landing plane? Yan Boxun asked rhetorically. This is an extremely dangerous hidden danger to maintain combat power! Of course. What if you say if both lifts are destroyed? In that case, I think the commander of your country will have to think about how to retreat and not continue the battle. ”

At this point, Xu Jie left a back hand, that is, he did not put forward the concept of the side chord lift in later generations. Of course. This has something to do with the fact that the lower hangar of the armored deck aircraft carrier is too close to the waterline, but it is very good to be able to communicate with the upper hangar even if it is possible.

"Now that you understand why we arrange the elevators this way, let's talk about the following problem, the problem of arson of aircraft carriers, which is the biggest difference between aircraft carriers and battleships in terms of defensive layout, there is a flammable and explosive product on aircraft carriers that battleships do not have, that is, highly volatile aviation gasoline. In a confined space or a poorly ventilated place, if the concentration of volatile oil and gas reaches a certain level, an explosion will occur when it touches a point of sparks. And in real combat, the possibility of producing Mars is too great. For example, a short circuit in a wire or an open flame or something. So there are two main ways to defend against this threat. One is to hinder the volatilization of oil and gas, and the other is to prevent the concentration of oil and gas from reaching the explosion point. ”

In Xu Jie's plane, there are two aircraft carriers that sank because of the problem of volatile oil, one is the Lexington, the largest aircraft carrier in the United States World War 2 was hit by the Japanese fleet in the Battle of the Coral Sea. The oil bulkhead at the front of the guide was cracked, and the forced ventilation measures failed later, and finally the guide exploded after encountering an open flame.

It can be said that the sinking of these two battleships is the most regrettable, especially Dafeng, after being hit by a torpedo, the speed was only reduced by 1 knot, and the first aircraft could be launched normally, but because of the violent vibration, the front elevator was stuck, and as a result, in order to release the aircraft, the book filled the front elevator with various items, and then continued to take off and land, which is also the fundamental reason for the failure of the ventilation.

In the face of this threat, Xu Jie's proposal to build yì is to strengthen the protection of oil depots, especially aviation gasoline depots, while using armor to protect them, but also to make concrete around them similar to the concrete bowls in later nuclear power plants. Even if the fuel leaks and volatilizes, it can effectively limit, and at the same time, the fuel delivery line is treated and protected in the same way. At the same time, the ventilation capacity is increased, and the air in the explosion hangar can be exchanged in a shorter time. Of course, in the end, when it is running, try not to refuel and reload in the hangar as much as possible. At the same time, the sprinkler and fire extinguishing equipment inside the battleship was strengthened. If something happens in the end, there's really no way around it. If the other party's firepower is too strong, God will not do it.

After solving the fire problem of fuel guide, the next thing that needs to be emphasized is underwater protection, underwater protection can be said to be a cliché, there is nothing to say, staggered layout and 5-layer underwater lightning protection system that is necessary, Yan Boxun's only meaningful construction is to set up a lightning protection protrusion when necessary to increase the depth of defense, and at the same time the stern adopts 4 rudders, and the distance of the rudder is opened to ensure that it will not be torpedoed. Finally, the thickness of the part of the armor belt that extends underwater should be larger. As for the rest, how thick the horizontal and vertical armor will be, that's another question. IN TERMS OF THE THICKNESS OF HORIZONTAL ARMOR, YAN BOXUN MEANS THAT 100MM THICKNESS IS BETTER, WHICH CAN AT LEAST BLOCK THE DIVE ATTACK OF 500KG ARMOR-PIERCING SHELLS. At the same time, an additional layer of armor is placed on the upper hangar deck to defend against fish that slip through the net.

"I don't know much about it, but I think it's really powerful." Afterwards, a British designer who participated in the construction of the Fury-class aircraft carrier once commented on Yan Boxun's conversation at the first Chinese British aircraft carrier design conference, because there were too many things in it that the British had never thought of, and the aircraft carrier had just appeared, and no one could have thought of what problems would arise in actual combat, let alone how to solve them. Yan Boxun seems to have the foresight to point out many possible problems in advance, which will have a serious impact on the survival of British aircraft carriers in naval battles in the future. So much so that the deepest impression of the Allies on British aircraft carriers in World War 2 was that they were sturdy! No matter how you fight, you can't sink it. Even in a later battle, in the face of the Anglo-American combined fleet, the German attack aircraft pilots received an order to sink the American aircraft carrier first, and the British aircraft carrier was listed as the second target. As a result, in this naval battle, an American aircraft carrier was hit with 7 bombs one after another, and 3 torpedoes were directly reimbursed, while the British aircraft carrier next to it missed a single bomb!

Designers sometimes talk about cannons, Yan Boxun's words made the British designer suddenly, (nonsense, the lessons of dozens of aircraft carriers in the 2nd World War in the later generations, of course, there are a lot of dry goods.) British naval officials were excited. The only one who cried was the wallets of the British. The ship was simply too big, and the construction requirements were simply too high. The original budget doesn't seem to be able to withstand Yan Boxun's toss like this. And that's not all, just when Yan Boxun blooded the British's wallet, the Huaxia Navy also followed suit!

"The aircraft carrier only provides a platform for the aircraft above, the real combat effectiveness still depends on the aircraft above, the carrier-based aircraft is to the aircraft carrier is like the artillery shell to the battleship, and its consumption rate is very fast, so the Huaxia Navy hopes that you can prepare enough aircraft for each aircraft carrier to double the full load, for example, if the Fury-class aircraft carrier can carry 110 aircraft, then your country had better prepare 220 aircraft and crews for it, in order to supplement the loss in wartime."

In history, the Japanese aircraft carrier fleet carried the largest number of aircraft at Pearl Harbor, and later with the continuous attrition of the war, its consumption was greater than the supply, so that in the Battle of the Coral Sea, the Zuizuru aircraft carrier of more than 25,000 tons could not even make up 60 carrier-based aircraft! Similarly, in the Battle of Midway, the numerical superiority of Japan's four main aircraft carriers was not obvious, and if you look at the aircraft carrier-based aircraft alone, it was only a slight advantage, with only 54 carrier-based aircraft and 44 aircraft on the Flying Dragon. The USS Yorktown has 79 planes, (the information here may be different, and I don't know much about the history of the war.) It's not that Japanese aircraft carriers can't be installed, but there really aren't planes to install!

"It's a lot of money!" When the budget for the battleship was finally put on Jericho's table for him to look at, looking at the long list of numbers, Marshal Jericho, who had not been excited for a long time since the end of the war, finally couldn't help it! "I think if those politicians saw the cost of this aircraft carrier and the money spent on the aircraft to be equipped for it, they would probably regret changing it to an aircraft carrier."

"Your Excellency, they will definitely regret it, because over time, the fighters will also need to be renewed. And in order to accommodate these aircraft, a corresponding airfield must be prepared on the ground. Thomas said to Jericho helplessly. I believe that our efforts are worth it. ”
