"The defense capability of our aircraft carriers is far greater than that of the aircraft carriers being built by the Americans. The main reason is that our aircraft carriers have armored decks that can ensure the safety of the hangar and part of the flight deck. But I think everyone understands,

It is impossible for the entire deck of our aircraft carrier to be covered with heavy armor, otherwise, this would really be a warship that would never be sunk." Yan Boxun said with a smile.

The British didn't react at first and didn't know what Yan Boxun meant by this sentence. "Because he will sink by himself when he enters the water because his center of gravity is too high and his weight is too heavy!" Yan Boxun's next sentence made the whole venue burst into laughter.

, a funny joke enlivened a somewhat dull atmosphere.

"The area protected by the armored deck of an aircraft carrier can only be the upper part of the hangar and the elevators connecting the hangars. Our hangar is 170 meters long. Together with the elevators at the front and rear, the entire armored deck is 200 meters long. This is probably the longest in the world.

Up to now

The longest horizontal armor so far? I remember that the length of your Queen Elizabeth-class fast battleship is less than 200 meters? And if we put an elevator in the middle, then the length of the armor plate will be longer."

Yan Boxun paused.

"Of course, you may say that the British Empire will not be stingy with money when building a maritime sword. It doesn't matter if the armor belt is longer. Now let's talk about what kind of hidden dangers it will cause if a lift is placed in the middle."

Yan Boxun said and took out a simple diagram. It marked the length of some decks and the schematic diagrams of the decks of two aircraft carriers with three elevators and two elevators respectively.

"Everyone knows that the internal equipment of a battleship will sometimes be disabled due to impact and vibration when the shell is not penetrated. For example, the gun rim is stuck. The same problem is faced by the elevator of the aircraft carrier, and because

The structure is more complex

The possibility of incapacitation is greater when bombing. Even if we add armor to the elevator, it cannot be completely avoided. Then we can look at this picture to discuss what happens if it is attacked by a bomb. Two-elevator aircraft carriers and three-elevator aircraft carriers

What difference can there be?"

"If one of the elevators in the dual-elevator aircraft carrier is attacked and disabled, it will not completely destroy our aviation capabilities, because no matter which elevator is destroyed, we have a runway of more than 200 meters to continue to take off and land aircraft, and even

It can take off heavy-laden aircraft. And if the elevator in the middle of our three-elevator aircraft carrier is destroyed, the entire aircraft carrier deck will be divided into two sections of almost equal length.

"The length of each section is about 130 meters, so tell me, what can be done at this distance? Is it a takeoff or a landing?" Yan Boxun asked. "This is an extremely dangerous hidden danger to maintain combat power! Of course. If you say what if

What if both elevators are destroyed? In that case, I think your commander will have to consider how to retreat rather than continue fighting."

At this point, Xu Jie left something behind, that is, he did not put forward the concept of side chord elevators in later generations. Of course, this is related to the fact that the lower hangar of the armored deck aircraft carrier is too close to the waterline, but even if it can simply communicate with the upper level

The hangar is also very nice.

"Now that everyone understands why we arrange the elevators like this, let us now talk about the following issue, the issue of arson on aircraft carriers. This is the biggest difference in the defense layout of aircraft carriers and battleships. There is a kind of flammable and explosive material on aircraft carriers that battleships do not have.

, that is highly volatile aviation gasoline. In a confined space or a place with poor ventilation, such as

If the concentration of volatile oil and gas reaches a certain level, it will explode if it encounters a spark. In actual combat, the possibility of generating sparks is too great. For example, a short circuit in a wire or an open flame. So let’s talk about our prevention methods against this threat.

There are mainly two types. 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 were two aircraft carriers that sank due to volatile oil problems. One was the Lexington, the largest aircraft carrier in the United States in World War II. It was hit by the Japanese fleet in the Battle of the Coral Sea.

After the hard fight, I felt good about myself and could still retract and launch the plane. However, due to oil and gas problems,

It caused an internal explosion in the hull and was ultimately unable to be saved. The other one was the famous Taiho armored aircraft carrier. This armored aircraft carrier, a masterpiece of Japanese World War II shipbuilding, was attacked by a torpedo, causing the front oil bulkhead to be shaken.

It cracked, and forced ventilation measures failed, eventually leading to an explosion 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, its speed was only reduced by 1 knot, and it could still launch the aircraft normally. However, due to severe vibrations, the front elevator was stuck. As a result, in order to release the aircraft,

The book filled the front lift with various items and then continued to take off and land. This was also the root cause of the ventilation failure.

In the face of this threat, Xu Jie's suggestion was to enhance the protection of oil depots, especially aviation gasoline depots. While using armor for protection, they also used concrete to build a surrounding concrete bowl similar to the concrete bowl in later nuclear power plants. Even though

The leakage and volatilization of fuel can also be effectively restricted. At the same time, the same treatment and protection have been done to the fuel delivery pipeline. At the same time, it also increases

With the addition of ventilation capacity, the air in the explosion hangar can be exchanged in a shorter time. Of course, the last step is to avoid refueling and loading in the hangar as much as possible during operation. At the same time, the spraying inside the warship should be strengthened.

and fire-extinguishing equipment. If something goes wrong after doing this, there is really nothing you can do. If the other party's firepower is too strong, there is nothing God can do.

After solving the fire problem caused by fuel, 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. The staggered layout and 5-layer underwater lightning protection system are necessary. Yan Boxun only proposed

A meaningful suggestion is to set up a mine protection protrusion when necessary to increase the defense depth. At the same time, use 4 rudders at the stern, and set the distance between the rudders to ensure that it will not be torpedoed.

That's it. Finally, the thickness of the part of the armor belt extending underwater should be larger. As for the rest, how thick the horizontal and vertical armor should be, that's another question. In terms of the thickness of the horizontal armor, what Yan Boxun means

The thickness is preferably 100mm, which can at least block the dive attack of 500kg armor-piercing projectiles. At the same time, another layer of armor is arranged on the upper hangar deck to defend against fish that slip through the net.

"Although I don't understand it very well, I think it's really powerful." A British designer who participated in the construction of the Wrath-class aircraft carrier later commented on Yan Boxun's talk at the first Chinese-British aircraft carrier design meeting, because there was too much in it.

There are many things that the British have never thought of. The aircraft carrier has just appeared, and no one can imagine what problems will arise in actual combat, let alone how to solve them. Yan Boxun seems to have the foresight to combine many possible problems.

Problems have been pointed out in advance, which will be helpful for the future

The survivability of British aircraft carriers in naval battles had a huge impact. In World War II, the deepest impression the Allies had of British aircraft carriers was that they were strong! They could not be sunk no matter how hard they were hit. Even in a later battle, when facing the British and American combined fleets,

German attack aircraft pilots

The order received was to sink the American aircraft carrier first, and the British aircraft carrier was listed as the second target. So in this naval battle, an American aircraft carrier was hit by 7 bombs in succession, and 3 torpedoes were directly canceled.

The British aircraft carrier next to it didn't hit a single bomb!

Designers sometimes just talk nonsense. Yan Boxun's words made the British designer suddenly enlightened. (Nonsense, there are certainly a lot of useful lessons learned from dozens of aircraft carriers in World War II.) The British naval officer was very excited. The only one who cried

It’s the British wallet that’s gone

. This ship is too big, and the construction requirements are too high. The original budget seems to be unable to withstand Yan Boxun's torture. And this is not over yet, Yan Boxun severely punished the British

When his wallet was bleeding, the Chinese navy also followed up with a stab!

"Aircraft carriers only provide a platform for the aircraft above. The real combat effectiveness still depends on the aircraft above. Carrier-based aircraft are to aircraft carriers like artillery shells to battleships. They are consumed very quickly, so the Chinese Navy hopes that you will

Being able to prepare enough aircraft for twice the full load of each aircraft carrier, for example, if the Fury-class aircraft carrier can carry 110 aircraft, then your country is best to prepare 220 aircraft and crews for it to supplement wartime losses."

Historically, the Japanese aircraft carrier fleet carried the largest number of aircraft when it was at Pearl Harbor. Later, with the continuous attrition of the war, its consumption was greater than supplies, so that in the Battle of the Coral Sea, the 25,000-ton Zuikaku aircraft carrier company

Even 60 carrier-based aircraft could not be assembled! This resulted in a significant reduction in combat effectiveness. Similarly, in the Battle of Midway, Japan’s four main aircraft carriers were outnumbered.

The advantage is not obvious. Looking at the aircraft carrier-based aircraft alone, they only have a slight advantage. An aircraft carrier as big as the Akagi only has 54 aircraft, while the Hiryu has only 44. The American Yorktown has 79 aircraft.

, (The information here may be different, I don’t know much about the history of the war.) It’s not that Japanese aircraft carriers can’t install it, it’s that there really are no aircraft to install it!

"This is really too expensive!" When the budget for this battleship was finally placed on Jericho's desk for him to review, looking at a long string of numbers, Jericho had not been excited for a long time since the end of the war.

Marshal Coe finally couldn't help it anymore! "I think if those politicians see the cost of building this aircraft carrier and the money spent on the aircraft to be equipped with it, I'm afraid they will regret converting it into an aircraft carrier."

"Marshal, they will definitely regret it, because as time goes by, fighter jets also need to be updated. And in order to accommodate these aircraft, corresponding airports must be prepared on the ground." Thomas said to Jericho helplessly. "

I believe our efforts are worth it.”
