"First, from the perspective of warships, aircraft carriers are now too fragile. Facing bombers, it is very easy to lose their aviation capabilities. If an aircraft carrier of 20,000 tons is hit by a 35oo kilogram high-explosion bomb, it may lose its aviation capabilities. It is unlikely that we can use fighter troops to completely intercept the opponent's attack aircraft group. So in this case, we must improve the protection capabilities of the warship, especially the protection capabilities of the bombs. So, if possible, I hope that the new aircraft carrier can lay armor on some flight decks." Logan said.

"Does the armor be laid on the flight deck? This is a very big challenge for the design and tonnage of the warship. You asked the Imperial Naval Ship Design Institute and the Bavarian Ship Design Bureau a very challenging question." Redel said with a frown slightly. He did not expect that the first question raised by Logan was so difficult!

"This is a very big challenge for the tonnage and center of gravity design of the warship. It is not possible to achieve at least 20,000 tons aircraft carriers. The length and width of the armored deck must support the minimum take-off and landing of the aircraft. Otherwise, horizontal armor with too small coverage area will not be meaningful to the warship. Moreover, in order to protect the facilities under the flight deck, this armored deck must also cover the hangar and the lower ammunition deck, oil deck and other key facilities. This determines that the area of ​​the armored flight deck will not be small, and the weight will also increase! In order to support the weight of the deck armor, the support structure of the warship must also be enhanced, which is likely to fall into a vicious cycle." Raidel said.

Redell does not understand aircraft carrier design, but he still has research on the protection and center of gravity of warships. Judging from the current protection trend of German battleships, the proportion of horizontal armored armor accounts for an upward trend. After all, the area of ​​horizontal armor is large, and the height of the armor belts on both sides is only 5 meters, which is 10 meters on both sides. Now the maximum width of the armor deck of the battleship is 20 meters up! The armor weight paid for increasing one millimeter is not of the same level. What Logan wants to enhance is horizontal protection, and he lifts this armor plate very high! This is a huge challenge for the center of gravity of the battleship. The easiest way is naturally to increase the tonnage, but the tonnage cannot be increased casually!

"Your Excellency has made a very accurate analysis of the length of the aircraft carrier armored deck, and I think it is of great reference value." Logan said sincerely.

"I think the area of ​​the armored deck is at least 120 meters. In this way, even if the worst situation occurs, such as if the front and rear edges of the armored deck are hit at the same time, then the 120 meters deck length and the overtime wind of the aircraft carrier can still be used as a built-in takeoff fighter jet, at least one squadron or more fighter jets, or more than 6 bombers. At the same time, this distance is enough for recycling aircraft, with a margin of more than 40 meters." Logan was also prepared, and had even thought about this issue before this battle, but this fierce attack stimulated Logan, which made him formally raise the issue.

"But this length does not seem to be enough to cover the hangar. The current hangar length is generally around 150 meters. In the future, aircraft carriers will be larger. For single-layer hangars, the area of ​​armored decks that need to be covered will be larger. My colleagues and I once calculated that if the future aircraft carriers still use single-layer hangars, then the length of the lifts at both ends may reach 190 meters, and the 190 meters long flight armored deck is simply unimaginable." Logan said.

"So, under the tonnage limit, we need to change our thinking, such as turning a single-layer hangar into a double-layer hangar, which not only increases the operating area of ​​the hangar, but also reduces the defense area of ​​the aircraft carrier's armored deck." Raidel said.

"Can a single-layer hangar become a double-layer hangar? This can indeed shorten the area of ​​the armored deck, but there is a problem that we must consider. If it is arranged as a double-layer hangar, the elevator may not be able to use a side-chord lift, because the side-chord lift cannot communicate with the lower hangar, because the lower hangar is almost close to the horizontal line, and the side-chord opening is not realistic at all. If a lift in the middle of the hull is used, then this elevator is an important safety hazard and occupies the area of ​​the hangar." Logan said.

"This is a matter of choice. The larger operating area of ​​the double-layer hangar is still very attractive, so we should continue to study. It is a big safety hazard to open a large hole with an area of ​​nearly 150 square meters on the main deck. This problem must be solved. So, I think this is possible, an internal elevator can be set up between the two hangars, and a side-chord elevator is used for transportation between the upper hangar and the flight deck." Raidel thought for a while and said.

"In this way, it will still occupy the space of the two-layer hangar, and it will also have some impact on the hull structure. For example, we can adopt an open structure in the upper hangar, but the lower hangar can only adopt a closed structure. The open hangar is convenient for warming up, the structure is smaller, and once it is attacked, it can quickly discharge smoke or combustible gases. I personally prefer a single-layer large hangar open structure." Logan did not expect that Redell also had such deep attainments in aircraft carriers. The result of the communication is that it is difficult for anyone to convince the other party.

"We can't seem to convince each other." Redel said helplessly.

"Yes, both solutions have their own advantages and disadvantages, and detailed data still need to be argued. Why don't we give up the dispute for the time being? I won't talk about this issue in the report." Logan made a concession first. In addition to both parties being reasonable, Logan believed that it should also be given a certain amount of respect to the other party.

"So good, let's talk about the issue now. If I'm not wrong, you should be preparing to talk about the carrier-based aircraft, right?" Redell said with a smile.

"You really have a sharp look. Can you tell me why you were thinking of this problem?" Logan said.

"I guessed right?" Redell asked.

"You guessed part of it, but not all of it. There is indeed a problem with carrier-based aircraft, but it is not simply a carrier-based aircraft problem." Logan said. "But even so, I still want to hear your views on current carrier-based aircraft." Logan said.
