Chapter 197 The Earth-shaking December (7)
The highlight of the reform in December was political and military structural adjustments, but it did not mean that he would do nothing in other fields. On December 8, five days before Hoffmann was about to set off for the UK visit, the Navy held a shipbuilding seminar to focus on the next generation of heavy aircraft carriers that had been designed.
This future-oriented heavy aircraft carrier is code-named Beihai class. It uses a 14-degree beveled deck, with an overall length of up to 321 meters. It is expected to have a standard displacement of 75,000 yuan, and is close to 90,000 tons after full load...
Hoffman frowned at the moment of hearing this technical indicator. The original displacement he set was 60,000 tons. There is a complete reason why he set this number but not a little higher: the Bismarck class has a displacement of 40,000 tons, and the H-class battleships repeatedly modified on the design drawings have a displacement of 55,000 tons. These two figures are within the affordable range of German ship construction capabilities. After years of shipbuilding development and European cooperation and coordination, it has been appropriately amplified to 65,000 tons. He believes that it can be done after a jump.
But the jump from 55,000 tons to 75,000 tons at once was too fast. Even if Japan provided the drawings of Yamato and Yamato class, it also expressed its willingness to provide relevant shipbuilding designers and engineers to help Germany build large warships. Hoffman also believed that it was too radical. After all, the Yamato class itself was at 65,000 tons, and 75,000 tons was also a new topic for Japan. Moreover, this was built by Japan under the strength of the whole country. Now that Japan has created another Yamato class or Yamato class, it is estimated that the other party will be unable to bear it.
After carefully studying the power system, he felt even more whimsical - the atomic bomb did not explode, so the designers wanted to use nuclear power on it?
He knocked on the table and shook his head slowly: "No, we cannot use the new power system. It is more than our experience to build this super aircraft carrier. Carrying new power that has never been verified and unknown when can be completed can only bring two results - either it will fail repeatedly after forcibly loading it and fall into the port every day, or it will be waiting on the ship platform for the new power system to mature. This aircraft carrier will not be able to get out of the sea without 10-15 years."
Several shipbuilding designers were stunned at first, and then nodded subconsciously - they actually didn't want to take the risk of adopting this new type of power that they had never seen before, but some people emphasized the need for innovation, so they moved this one up.
"Head of the People's Republic of China, we also have a plan for conventional power layout, with a standard displacement of about 77,500 tons."
Hoffmann opened the so-called drawing b and saw that 108 standard jets were equipped with a scale of 108.
The design prerequisite for the new generation of aircraft carriers must have the ability to carry jets, but the specific number was not stated at the beginning. Obviously, the Navy has not yet understood the meaning of precise strikes, and is still using the conventional attack capabilities of the propeller era as a measure, mistakenly thinking that a single aircraft carrier still needs to be equipped with so many aircraft after the war.
"These 108 planes?"
"Considering that the jet is larger and faster, it requires a longer take-off and landing deck, so..." Major General Ludwig, who was responsible for the overall design, subconsciously explained.
"I'm not thinking that it's too little, I'm not thinking that it's too much..." Hoffman pondered, "Cut off the indicators, and the standard displacement is recommended to be controlled at 60,000 tons, and it is absolutely not allowed to exceed 65,000 tons. It is not possible to carry 108 aircraft so many, 70-80 aircraft are enough, and I even think 72 is enough."
"72 enough aircraft" soon blew a gust of wind at the scene, and everyone looked at each other: the axial level with a displacement of only 25,000 tons can carry 70+ aircraft. The head of state actually said that only 72 aircraft carriers of 60,000 tons in the future will be enough? But Hoffman insisted that the future is an era of precision strikes, and there is no need for so many aircraft, and improving single-air combat capabilities is the king.
"In addition, heavy armor has little significance to aircraft carriers. I fully agree with strengthening airworthiness capabilities, but armored aircraft carriers wrapped in heavy armor are outdated." Hoffman inspired them, "Can any heavy armor withstand the attack of silkworm missiles with a warhead weighing up to 750 kilograms? Can it withstand the attack of 800 kilograms of armor-piercing missiles?"
"We evaluated and believed that the 750 kg missile could not penetrate the main defense zone."
"Then can I increase the missile warhead to 1,000 kilograms or even 1,500 kilograms?" Hoffman waved his hand, "Gentlemen, it is obviously much easier to increase a missile by hundreds of kilograms than an aircraft carrier to enhance its defense capabilities, let alone efficiency. You must pay attention to the construction time. If the aircraft carrier reaches the level of defense you designed, I am afraid that one can't be built in 10 years - what are the aircraft carriers going to do? They will be outdated when they are built!"
"You should also reconsider the runway and catapults. In the future, aircraft of the level of ju-288 must be able to take off with full load. The aircraft carrier needs an air command aircraft, which will be very heavy." The concept of early warning aircraft is not popular yet. After Hoffman described it as a command aircraft, everyone understood it.
In less than 2 hours, waiting outside and waiting for the head of state to summon several German aircraft carriers to explain technical details. The backbone designer of the Italian aircraft carrier was frustrated and got an answer - rework!
The directive is very clear: tonnage reduction, conventional power, aircraft reduction, weakened defense, and optimized layout... One ship must be built within 5 years!
In such a democratic country, some people must be rushing to complain about the layman leaders and the leaders intervene randomly, but now it is the country and society. Who dares to say something irrelevant to the head of state? Besides, the content of the head of state is also the focus and concerns of the controversy in the daily design of designers. Now, some people can naturally calm the debate by speaking publicly.
Sperer is obviously willing to tow the new aircraft carrier again. At present, the Yunlong and Dafeng classes in German and Italian shipyards have not yet been put into service, not to mention that the improvement time is very short. The axial levels who have just laid keels and built in batches have to complete these tasks at least after June 1947.
He immediately explained his idea to Hoffman: "First of the People's Republic of China, can we build a transitional aircraft carrier that is fast, medium-sized, and not too expensive, suitable for commonly used in the axial level?"
Hoffman nodded and expressed his approval: "I intend to make appropriate optimization and strengthen on the basis of the axial level to build a bevel aircraft carrier, so that Britain, France and Italy can participate together. If Japan is interested in it in the future, it can also participate together. Position it as the EU-level: appropriately amplify based on the axial level hull, standard bevel angle, standard displacement is controlled within 27,000 tons, and no less than 48 jet carriers. A joint meeting of four European countries to build ships will be held at an appropriate time for confirmation, and the drawings will be determined no later than June next year."
There were actually quite a few plans to build a ship by Hoffman at the meeting on this day, and the second batch of ship-building plans reported were also mercilessly rejected.
After Germany completed the construction of the Z-class destroyer, all the destroyers built were Hedgehog class. Then, due to insufficient tonnage, the naval system proposed to build an air-defense light cruiser that increased its displacement to 6,000 tons. The construction cycle of this class is longer and has not been put into service so far. Even the fast and batch-built Hedgehog class has only 18 ships - this has put in a lot of effort! I remember that it was not so fast when the Z-class was built.
The construction ideas of the Porcupine-class are easy to understand. They are designed in Hedgehog-class, and they adopt tonnage amplification routine. This is a conventional practice of the Third Reich Navy. Several battleships looked like heavy cruisers amplified, so that the British were able to make mistakes in the North Sea Navy and eventually ruined the Hood.
After several contacts with the Cleveland-class and Atlanta-class light cruisers in the United States, the Navy took advantage of the situation and proposed that 6,000 tons of water displacement was not enough, hoping to build a professional air defense cruiser of 10,000 tons. Hoffman decisively refused this idea.
He clearly knew that the mainstream trend of the world's naval after World War II was the process of the large-scale transformation of destroyers and the gradual disappearance of cruisers. From the perspective of the naval field, the core of the combat force was the aircraft carrier formation, and destroyers were the key auxiliary forces in the aircraft carrier formation. Only the Soviet Union focused on developing cruisers to perform single-ship or small-scale combat missions because of the ineffective aircraft carrier power, and built a batch of cruisers.
As the difference between cruisers and destroyers began to narrow, a major East Asian country has also introduced several modern-class ships - looking at the mighty, it really makes people have no survival in the battle between fleets.
But he did not simply deny the idea of air defense cruisers, but put forward a new concept: the new generation of destroyers must be larger, and the tonnage division between traditional destroyers and light cruisers will be abolished. New construction indicators include:
1. The tonnage is moderately amplified to 7,000 tons, which can accompany the aircraft carrier formation to perform strike missions;
2. Multifunctional integration, integrating air defense, anti-submarine, support, and reconnaissance integration;
3. Diversified attack methods can be used, naval guns, torpedoes, deep-water bombs and missiles;
4. Must have the ability to carry helicopters.
Considering that this 7,000-ton large destroyer is expensive, he also put forward the idea of "high and low matching" - to build a low-cost frigate. The frigate considers using 2,500-ton hull to perform regional sea combat missions, and focuses on single performance: including missile frigates, anti-submarine frigates, air defense frigates, etc., and only inherits 1-2 of the main functional modules of large destroyers.
However, both large destroyers and frigates are auxiliary members of the fleet and are not the core of the fleet's strike force. They cannot undertake front-line combat tasks alone. They must cooperate with aircraft carriers, submarines and other warships.
The Navy carefully interpreted the new concept expounded by the head of state and found that the difference between light cruisers and destroyers, light cruisers and heavy cruisers could not be completely separated.
There are almost no countries in the world to build heavy cruisers. Japan has the most heavy cruisers in the world - more than the total of other countries. Hori Teki also disagreed with the new heavy cruiser that took a long time in the new shipbuilding plan, but he expressed his strong interest in the Porcupine-class and the American Auckland-class air defense cruiser, intending to build a universal air defense cruiser for the Three Kingdoms after the Axis class, and even hopes that European countries will help Japan build after the war.
Chapter completed!
