Chapter 1368: Dinghai Divine Needle
Therefore, in order to completely overwhelm the Allies in terms of technology and performance, Huaxia planned to develop a supercarrier capable of fully operating twin-engine aircraft and jet planes in the last period before entering the war! 30,000 tons of aircraft carriers can no longer meet the needs of China, and even 40,000 tons of warships are a little small, Xu Jie decisively asked the number of standard cards of the new aircraft carrier to be more than 45,000 tons, and the highest is not more than 52,000 tons!
"If I could, I would recommend a double-decker hangar for a new aircraft carrier, of course, only if there is enough hangar height to accommodate the new aircraft. If that's not guaranteed, consider using a single-storey hangar! Xu Jie hesitated and said the first request.
From the bottom of his heart, Xu Jie still prefers the double-storey hangar, in addition to the large internal usable area, the deck defense area of the double-storey hangar is actually smaller than that of the single-storey large hangar! In the case of the historical Essex-class aircraft carriers and the USS Taiho, if the armor plates are also required to cover the upper deck of the hangar, the length of the hangar in Essex reaches 200 meters! The length of Dafeng's hangar is only 150 meters, and the width of Essex's hangar is also larger, if you count the deck armor coverage area, Essex's required armor may be about 4% higher than that of Dafeng! The increase in the weight of the armor will inevitably cause a series of problems such as structural weight and stability. However, the biggest advantage of a single-story hangar is that the height is sufficient. In fact, the increase in the volume and weight of the aircraft is much faster than the increase in the tonnage of the aircraft carrier. If it were only a 2-battle propeller aircraft, then the design with a double-decker hangar and an armored flight deck would undoubtedly be the best. But once jets and twin-engines were on board. The height of the double-storey hangar makes it difficult to ensure the normal operation of the aircraft.
If you want to have both an armored deck and a double-deck hangar to maintain height, I'm afraid the stability of the battleship will be very problematic, look at the historical Dafeng, the hangar is smaller than the Zuihe, the deck is larger, and it is basically understandable that it has the same aviation capabilities. But the part above the water surface of the Taiho is almost one deck lower than Zuihe! Zuihe's lower hangar is one deck level away from the waterline, while the lower hangar of the Taiho is basically at the waterline! Single-storey hangars, on the other hand, generally have less usable area than double-storey hangars. Twin-engine aircraft and jet planes are generally very large, so this contradiction between hangars and airplanes will be unprecedentedly acute. The only solution for later generations was to throw most of the planes on deck.
It's a pity that Yan Boxun, who participated in the meeting, didn't know the intention of figuring out the leader, since Xu Jie said that he could use a single-story large hangar. Then Yan Boxun decisively ignored what Xu Jie said earlier, and directly chose a single-story large hangar on the issue of hangars for future aircraft carriers! Because this design is the easiest and most reliable!
"The beveled deck of the aircraft carrier must be increased, which can be made to 15 degrees as appropriate. And the length of the beveled deck must also be sufficient. Well, what about the shape? That's how it was designed. After speaking, Xu Jie directly took out a plan of the aircraft carrier Forrest that plagiarized the Americans, in fact, Midway is just a half-baked product, and only the USS Forrest aircraft carrier is the real origin of the modern supercarrier. Of course. This aircraft carrier is just a rough appearance, and the deck and size of the new aircraft carrier in China are still much smaller than Forrestal, after all, the latter is an aircraft carrier of more than 60,000 tons!
"Boss, you've said so, we're going to design a hair!" Yan Boxun said dissatisfied. "Anyway, it's about making sure the flight deck is as big as possible, the middle and rear of the deck is as wide as possible, and having a large deck area, right? Is the hangar closed or open? How is the armor arranged? Why don't you explain it all! Yan Boxun said, he found that in front of Xu Jie. It seems that the work of the battleship designer himself has become very small!
"Hangar? If it is a single-story large hangar, first make the front end open and the back end closed. The hangar was divided into three areas, namely the fighter hangar, the attack aircraft hangar and the maintenance hangar in the rear. The length of the hangar should be around 200 meters, and the width should be as wide as possible, preferably with a maximum width of more than 27 meters. IN ADDITION, THE HORIZONTAL ARMOR LAYOUT IS DIVIDED INTO TWO LAYERS, THE UPPER LAYER IS AN ARMORED FLIGHT DECK WITH A THICKNESS OF 100MM. The second layer of horizontal armor and the side armor belts were connected to form an armored box. THE THICKNESS IS DESIGNED ACCORDING TO 75MM. THE SIDE ARMOR DOES NOT NEED TO BE TOO THICK, 105MM IS ENOUGH. In addition, the defense of aviation gasoline depots and ammunition depots must be strengthened, especially the former, constantly with sufficiently thick armor around them. A concrete hood was also constructed of concrete to prevent the depot shell from rupturing and causing fuel to escape. Xu Jie thought for a while and said.
Thinking of this, Xu Jie couldn't help but complain about the defense designed by the Americans in history, the horizontal protection of Midway Island is divided into three layers, namely the flight deck steel and armor thickness of 3.5 inches, and the armor thickness of the hangar deck is 2 inches. Then below, that is, the thickness of the lower horizontal armor of the armor box formed on both sides of the 8-inch armor belt is 2 inches, and a horizontal defense is actually designed with 3 layers of armor, and Xu Jie is also drunk. In fact, the best way to defend is the 2nd layer, which is what the Japanese did when they designed Taiho, the flight deck armor and the bottom armor box horizontal armor, and the armor of the hangar deck is removed. In this way, even with the same physical thickness, the latter has better defenses than the former, and too many layers of horizontal armor will weaken the defenses.
"For the defense of the ammunition depot and fuel tank, we wanted to deal with a new defense system, because the ammunition depot and fuel tank are at the bottom of the battleship, below the waterline, so it is actually difficult for both shells and bombs to hurt these places, the former because it is difficult to hit, and the latter because there are two layers of horizontal armor protection with a total thickness of 175MM. If you want to penetrate, I'm afraid that the attacker's armor-piercing ability must be at the level of X-bullets in history to be possible. If you really want to be lined up in these positions by this bomb, then you can only admit it. The real threat is still torpedoes, especially submarine-launched torpedoes using magnetic fuses, these torpedoes are equipped with about 500KG of explosives, exploding in the hull, and the shock wave generated directly hits the bottom of the hull, which is the most vulnerable of the battleship's mine protection system. And aviation gasoline tanks and ammunition depots cannot be set up redundantly, like the power compartment, and once hit, it is fatal. So we deployed armor at the bottom of the ammunition depot for the new warship! Yan Boxun said.
In order to ensure the safety of the ammunition compartment, almost the entire ammunition compartment is in the armored package, and even the bottom of the ammunition compartment has a defense of about 5 inches. Because the depth of the bottom of the hull is definitely not comparable to the sides, the only way to improve the lightning resistance of the bottom of the hull is to replace the depth with armor, and use the bottom armor and 3 layers of hull, such a defense is basically enough. Of course, such a design is very costly, both in terms of cost and weight. It is not suitable for its deployment in the power compartment, so the defense of the power compartment can only depend on the alternate arrangement of compartments and power systems and luck!
"Isn't the variety of aircraft we deploy on aircraft carriers too mixed?" Ye Ming, who was on the side, looked at the carrier-based aircraft configuration of the future super-large aircraft carrier and said with some doubts. In Ye Ming's opinion, the jets of the above two squadrons are a must, because they are the core of the fight against the German fast fleet, they are the strongest shield of the fleet and the sharpest sword of the fleet. In defense, they could use their high speed to catch up with the opponent's bombers and smash them to pieces, while in the attack, they were responsible for tearing through the thick air defense nets of the Germans. Twin-engine aircraft of two squadrons were also needed, jet fighters were the basis of the fleet's self-preservation, and the large ammunition and high range carried by twin-engine aircraft were the sword of Damocles hanging over the head of the German fleet. Twin-engine aircraft with plates (radar antennas) on their backs, or sonar buoys with folded sonar buoys on their bellies, are multipliers of fleet power, and the former provides early warning from the air. The latter is used to hunt down deadly assassins hiding in the depths of the sea.
As for the Seagull fighters on the configuration table, he thinks it is necessary, after all, the number of jet fighters will be relatively small, and the low deck requirements of propeller aircraft allow these aircraft to make up for the lack of air fighters at any time, and the longer stay time in the air can also ensure that the air defense of the fleet will not be interrupted. Jets can only play an important role when they are used at the right time. And in Ye Ming's eyes, the Seagull is also a good attack aircraft, except that it is not very suitable for carrying torpedoes. It's very good as a dive bomber. Well, it has not yet adapted to the change in the status of the Seagull, and has always treated him as a bomber and not a fighter!
BUT WHAT ABOUT A PURPOSE-BUILT GROUND ATTACK AIRCRAFT ON THE LIST THAT HAS A MAXIMUM TAKE-OFF WEIGHT OF MORE THAN 20,000 POUNDS AND A MAXIMUM FLIGHT SPEED OF LESS THAN 600 KM? If this wasn't a document compiled by the Admiralty, Ye Ming would even think it was just a joke, he could hardly imagine that the Navy was planning to build such a heavy single-engine propeller bomber! And the speed of this aircraft is not outstanding, the maximum speed is only 312 knots, which is not even 600 kilometers. What is even more frightening is the bomb load of this aircraft, if the content of this document is true, then this aircraft has 15 hardpoints! Among them, the two hardpoints on the inner side of the wing and the hardpoint in the middle of the belly have a maximum payload capacity of 2,000 pounds! The outside of the wing has 12 hardpoints. Each anchor has a capacity of 500 pounds! And looking at the maximum design load, it actually reached a bomb load of 8,400 pounds against the sky! Ye Ming thought that the buddy in charge of HNA wanted to go crazy with attack power and designed such a terrifying Dongdong! In terms of bomb load, it is even better than the German JU88! By the way, this plane also has 380 gallons of internal oil! If it is converted to the weight of oil. THEN THIS NUMBER WILL BE 1150KG! Think about it, the total weight of the internal oil and bombs is about 5 tons! The Germans' JU88 doesn't have the ability to do this either! He is really suspicious now that the relevant personnel have made a mistake in the remarks of the information!
Well, this time Xu Jie plagiarized the classics of a certain great country in history, which is the AD Heavenly Raider attack aircraft that was called the last piston samurai by later generations! This aircraft is such a classic that when other piston propeller aircraft of his time have been retired from active service in the United States, this aircraft is still firmly in service with American aircraft carriers. Fight for the good of Uncle Sam. Even in the dense forests of Vietnam, in addition to competing with the opponent's ground units, this aircraft has also shot down MiG fighters at low altitudes, although there is some element of luck in it, but it is not easy for a professional piston attack aircraft to have such an honor. Of course, the tech tree of this aircraft may be a bit high, as it uses an R3350-26WA engine with a maximum output of 2700 hp (this is not WEP power, not a drug!). The normal output of the engine is 2300 horsepower! For the Huaxia and Entente countries, which have not even made a good deal of R2800 level engines, this aircraft may still be far from entering service.
"This aircraft is a bit out of place with the current pairing, the large range and bomb load are his biggest advantages, but the problem of air combat ability and slow cruise speed makes it difficult to group with existing aircraft. In the future aircraft carrier confrontation, the high-speed aircraft group is the main means of breakthrough, and the integration of fighters and bombers is the ultimate choice of carrier-based aircraft. Ye Ming asked questions in front of Xu Jie.
"Let's be the second wave of mending, and in the future our aircraft carrier fleet will definitely support ground operations, if you talk about cost performance, this new aircraft is the most cost-effective, and its large bomb load is not inferior to that of medium bombers. Imagine if one of our aircraft carriers could take off 24 planes carrying more than 3 tons of bombs at once, what a terrifying attack power! Xu Jie didn't care about the former's attitude and said. Everything must be prepared as soon as possible, now the fast attack speed of the Huaxia and German fast groups is an advantage, but the lethality is slightly insufficient, the best way is for the first wave of fast groups to tear through the opponent's defenses first, and then the second wave of the Huaxia version of the Heavenly Raiders with a large number of bombs take advantage of the situation to kill and sweep the tail. In the face of a super attack aircraft equipped with 3 torpedoes, there will definitely be no such thing as being injured but not dying. And from the point of view of ground support, the Skyraider is definitely the most cost-effective carrier-based aircraft in this era! Otherwise, it won't be used after World War 2!
