Yang Yonglin said for a long time, in fact, it can be summed up in a few sentences, first, the number of large armored aircraft carriers is not enough, and it is necessary to use medium-sized aircraft carriers that are easy to produce by attacking the strong and defending the weak to make up for the number. Second, the specifications and standards for medium-sized aircraft carriers need to be determined urgently. Thirdly, in order to ensure the smooth flow of lines of communication, light aircraft carriers are needed to ensure the safety of lines of communication. On the surface, the situation Yang Yonglin said is very similar to the 2nd battle in history, but Xu Jie still found many differences after careful consideration, if you start from the perspective of escort, then the light aircraft carrier of this plane must not be replaced by the crispy skin of the Jeep aircraft carrier in history, because their opponents are more ferocious than in history!

In addition to ground support, escort aircraft carriers in history undertook escort missions. And what is the essence of the escort mission? In fact, it is to deal with submarines, and not necessarily to sink submarines, as long as they can be suppressed under water and cannot pose a threat to the transport fleet. Although the speed of the escort aircraft carriers is generally not high, and the defense is also okay, it is not too much to say that some escort aircraft carriers are civilian ships. Even then, submarines under water are helpless in the face of various anti-submarine aircraft on escort aircraft carriers. Anti-submarine aircraft squads equipped with radar and self-guided torpedoes and depth charges can destroy any submarine that dares to show its head, while underwater submarines generally have a speed of only about 6 knots. It is simply impossible to launch an attack on escort carriers. So the result is that although the escort aircraft carrier itself can be on the coffee table, the cost is low, and at the same time, the submarine is difficult to have a chance to attack, and the weakness of the aircraft carrier itself is covered.

But this plane escort carrier has encountered an even more ferocious and difficult opponent. If all the escort tasks are handed over to those escort aircraft carriers in history, it will definitely not work. This opponent is an aviation cruiser that has never appeared in history, but has been carried forward in this plane! A very important task of the aviation cruiser when it is designed is to break the diplomatic battle, so in the future there will be a battle between the escort aircraft carrier and the aviation cruiser! But if the historical escort aircraft carriers are still used, this cheap low-grade cargo is undoubtedly more than auspicious for an aviation cruiser armed to the teeth.

If you look at it only from the point of view of aviation performance. The deck length of the escort aircraft carrier is between 150 and 170 meters, and the width is around 22 meters. The carrier aircraft capacity is about 30 aircraft. If you look at these data alone, the gap in aviation capabilities between escort carriers and air defense cruisers is not large. But in practice, it is much worse. The reason is simple. The speed difference between the two is too great. As a result, the deck wind speed required for take-off is insufficient, which in turn directly affects the efficiency of take-off. According to the standards of the Chinese Navy, the premise of the take-off and landing distance of the aircraft is calculated when the aircraft carrier is sailing at a speed of 25 knots. If the speed is faster, then the required take-off distance will be shortened, and vice versa. And historically, the speed of escort aircraft carriers generally did not exceed 20 knots! All heavy-duty aircraft must take off and land with catapults, you know, although the power of the catapult increases in the later stage, but at the same time the charging time will also increase, which is used for anti-submarine purposes. Small formations of 3-5 take-offs are okay. However, when put into the fierce naval and air battlefields, the tragic take-off and landing efficiency greatly reduced the combat effectiveness of the escort aircraft carriers.

As the saying goes, how can you stand by the river without getting your shoes wet, and the air defense capability of the escort aircraft carrier itself is weak, so it is almost inevitable to be stabbed! As long as a 500kg high-explosive bomb hits the middle of the hull, the ship will basically not be able to go back, the number and strength of the compartments of the civilian ship are already very poor, and the staggered layout of the armor and power compartment will not be there. But the 30 planes above are not cheap. And the need for at least 1,000 officers and men on an escort aircraft carrier is not something that can be measured by banknotes. Let an aircraft carrier sink to the bottom of the sea with about 2 dozen planes and hundreds of people with a single bomb? I guess no country would be so generous, right? …

On the contrary, looking at the aviation cruisers, the ability of escort aircraft carriers to take off and land heavy-duty attack aircraft is already limited, and they face interception in the air, dense anti-aircraft fire, and excellent fire control. Whether the single-digit aircraft that escort the aircraft carrier takes off and lands can cause damage to it remains to be seen. Even if a 500kg bomb falls on an aviation cruiser, with a little luck, the battleship can still have aviation capabilities, and the safety of the core compartment can be guaranteed by luck. In exchange for a moderate damage for an escort aircraft carrier and a bunch of transport ships, the air cruiser side can be said to have made a lot of money! Generally speaking, it is good for an escort fleet to have at most one escort aircraft carrier. Even if the aviation cruiser loses its aviation capability, people still have naval guns, right? There is no pressure to go up and pursue a merchant ship with a speed of about 12 knots, and if you run into a destroyer that is not long-sighted, you can be stoned to death along the way.

Therefore, in order to ensure the smooth flow of communication lines in this plane, then it is necessary to allow the escort aircraft carrier to suppress the aviation cruiser. What are the criteria for suppression? In short, there are more planes than you and more flying than you. The protection is passable, at least not seconds. In addition, the speed must be fast, if it is less than 20 knots. In the face of an aviation cruiser with a maximum speed of more than 30 knots and a cruising speed of more than 20 knots, how can you chase it! When fighting on the oceans, the maneuverability advantage of speed is enormous, especially when quick maneuvering is required in the face of war.

The design of the battleship should be based on the completion of the mission first, and other things such as cost and construction period should be put second. In order to fully suppress aviation cruisers, the number of carrier-based aircraft should be no less than 60 units. And the ability to release must also ensure that about 27 aircraft are released in a wave. To be more detailed, there must be about 8 torpedo planes out of 27 aircraft, and the remaining bombers must also be able to carry bombs of the 500kg class. The former, naturally, is the best weapon against battleships, while the bombs of the latter can also pose a serious threat to aviation cruisers.

In order to achieve this release requirement, the length of the flight deck must be more than 210 meters, which is justified, if a bomber loaded with torpedoes and 500kg bombs wants to take off by taxiing, it needs to be at least about 150 meters away, and 15 planes, it needs to be put in about 4 rows (in the state of folding wings). Counting the interval in between, a total of more than 50 meters is required for 4 rows of aircraft. Consider the width of the widest part that can fit four planes. Then the width of this aircraft carrier should also be more than 25 meters.

As for the defense capability? Xu Jie's idea is that the ammunition depot must be able to block the attack of 500kg semi-armor-piercing shells, so the armor thickness on the top of the ammunition depot should be more than 90mm. And it can be filled with water in time to prevent explosion. The protection standard of the power compartment is to defend some areas against 500kg high-explosive bombs. At the same time, the staggered layout is adopted, at least it is guaranteed that all the power will not be destroyed by a single bomb. And in terms of underwater protection, both the division of compartments and the thickness of anti-mine armor are set according to the standards of warships. As for speed? At least a speed of more than 25 knots must be achieved to ensure the deck wind speed of the carrier-based aircraft and the need for rapid maneuvering in the ocean. Under these requirements, the full tonnage of such escort aircraft carriers directly exceeded 15,000 tons. And the cost is definitely not very cheap.

"Why do I think this design standard is so familiar?" Xu Jie looked at the words on the paper and said depressedly. If you add a double-decker hangar, then reduce the defense level of the ammunition depot, and then set the speed at more than 30 knots, then it will be the cloud dragon in history! Xu Jie flipped through another piece of paper next to him, this paper was written on the data of the Independence-class light aircraft carrier in history, and after careful comparison, Xu Jie found that in the case of a difference of several thousand tons in tonnage, the combat effectiveness of the Yunlong was about twice as strong as that of the Independence. Moreover, the production cycle of the Yunlong is not very long, and with the industrial capacity of the historical Japanese coffee table, it takes no more than 2 years to build a Yunlong. The construction cycle of the Independence is more than 1 year, so in Xu Jie's opinion, the Yunlong aircraft carrier is obviously better in terms of combat effectiveness, construction cycle and cost performance. …

Moreover, the Yunlong aircraft carrier can also be used as a fleet aircraft carrier, and the better hardware performance allows him to fully serve as a fighter flight mission, and at the same time, it can also release some attack aircraft to make up for the lack of attack power. In Xu Jie's vision, the secondary fleet aircraft carrier based on the Yunlong aircraft carrier could be used not only for fleet operations, but also for hunting aviation cruisers on the ocean. But because Yunlong is not cheap after all, the number of such aircraft carriers will not be too much, and the number of escort aircraft carriers that have built hundreds in history is definitely incomparable.

Therefore, Xu Jie's arrangement of the secondary aircraft carrier is like this, dividing the sea surface into high-risk sea areas and low-risk sea areas, the former is naturally the area where the German fleet and aviation cruisers may appear, while the latter is such as the Bay of Bengal, the South China Sea and the Pacific Ocean, where large German warships generally do not go, but there will be submarines. On the one hand, the Yunlong aircraft carrier is responsible for making up for the shortcomings of the fleet's operations, and on the other hand, it is also responsible for intercepting and killing the possible Allied fleets in high-risk sea areas. As for the escort aircraft carriers with the bottom of various civilian ships, they can be used to hunt submarines in low-risk waters.

However, although it was decided to use the Yunlong aircraft carrier as the mother type, Xu Jie still had to improve it, and the first thing to do was to reduce the speed of the ship, and the overload speed could reach 30 knots. A 15,000-ton ship with 100,000 horsepower is enough. The second is to convert the double-storey hangar into a single-storey large hangar, which saves weight to increase the deck area. Insufficient number of aircraft can be solved with hang tickets and deck mooring. And after such a change, Xu Jie found that his aircraft carrier was a bit like a miniature version of Yorktown. Well, how do you say that? Count it as the tonnage of the cloud dragon, the design of York City!
