In this case, the Germans can only use the Luoyang engine factory not long ago successfully developed and finalized the production of 1500 horsepower air-cooled engine emergency, with the help of China's current Shijie first exhaust gas turbocharger, its actual maximum output reached 1650 horsepower, although not as good as the 2100 horsepower of the American "double wasp" engine (the first mass-produced model is actually only 2000 horsepower), but at least it can barely make use of it

What's more, after obtaining the support of Jishu and personnel from Germany (after all, our foundation is still too thin, and we have taken advantage of ideas and materials before, so it is still very important to introduce them.) The development of the engine is certainly much faster than before, and it is entirely possible to launch a more Haode product before the F4U is finalized.

Besides, after obtaining new materials, the Germans themselves are also developing new aircraft engines, although the fighter engines are mainly liquid-cooled, but BMW is developing air-cooled engines for the FW-190 fighter under development at this time, and as a result, the German Navy hit it off and began to develop a new air-cooled engine for the F4U "Corsair".

It is worth mentioning that this incident also led to a series of laughable farces, BMW's development of aircraft engines for the Navy angered the fat man who has always insisted that "everything that can fly must be in my charge", which directly led to the FW190 fighter under development being forced to abandon the air-cooled engine developed by BMW and switch to a liquid-cooled engine produced by other companies, so that the aircraft design had to be greatly changed. As a result, the performance of the FW190 fighter was not as good as that of the F4U "Corsair", and after such a delay, the performance gap was even more huge. No matter how stubborn Goering was, he could not ignore the widespread call of the pilots and allocate funds for the Navy's carrier-based aircraft for the temporary use of the Air Force. I really knew this was the case, so why bother in the first place? Although Ge Fatzi used his power to force the Navy to name this model "FW190", it was he who lost face

For the same reason, the "FW190" fighter did not exactly copy the original design of the F4U Corsair. Absorbing some of the advantages of the original FW190 design, and also making certain improvements to some of the original defects of the F4U "Corsair", such as poor vision, etc., these changes make the appearance of the "FW190" quite different from the historical F4U "Corsair". Therefore, the Americans only thought it was a coincidence at first, and it was not until after the war that they understood that the Germans had copied their design, and the design drawings were actually provided by the Chinese, which was also one of the important reasons why McCarthyism in the early days of the Cold War in this time and space was more powerful than in history, but it was not the fundamental reason.

Hu Weidong's blueprints were not provided for nothing, and in exchange, Germany needed to help China build a production line with a production capacity of more than 150 aircraft per month. It is specially used to produce this carrier-based fighter, which is named "Hai Jian-1" by the Chinese side, so that Chinese pilots can accumulate experience in operating all-metal fighters and carrier-based fighters. It is also worth mentioning that in several revisions, there are certain differences between the design chosen by the Chinese side and the one chosen by the German Navy, plus both countries finally chose their own engines (after all, Germany has a thick foundation. After obtaining new materials, the level of engines soon surpassed that of China, but China has always maintained a certain advantage in turbochargers. So there is a certain difference in performance, to put it simply, the German "FW190" has better low-altitude performance, while China's "Sea J-1" has a greater advantage in high altitudes, although the former is more important for carrier-based aircraft, but China without an aircraft carrier actually uses these carrier-based aircraft as land-based aircraft, so there is no big problem

It must be admitted that the Germans, though conceited, were still very modest in areas where they were clearly not good at it, so Hu Weidong's suggestions for improving the Zeppelin aircraft carrier were quickly accepted by the German Navy, which knew that it was indeed inexperienced in this area, at least much more easily and smoothly than the big discussion around the design of the Hindenburg-class battleship. In addition, although the layout of the Zeppelin is a mess, the hull is still very good, and the armored flight deck in the original design (Note 1) will limit the number of aircraft carriers, but it can greatly enhance the survivability of the aircraft carrier, which is not necessarily a wrong choice for the German Navy, which has only one aircraft carrier in total, not to mention the lack of high-quality timber suitable for making flight decks such as teak. Of course, Hu Weidong, an expert, still put forward a lot of very constructive opinions and suggestions on the specific armor arrangement.

Therefore, in the end, the Zeppelin only removed the 16 150mm naval guns, appropriately adjusted the armor arrangement, strengthened the close fire resistance, and the number of carrier aircraft was only increased to 54 (up to 60), including 18 carrier-based Stuka dive bombers and 36 "FW190" carrier-based fighters. Considering the excellent performance of these two carrier-based aircraft and the non-human super-aces of Germany, the combat effectiveness is not necessarily worse than that of the aircraft carriers of the United States and Japan, which have more aircraft, but unfortunately, after all, there is only one, at least temporarily. It must also be noted that although the number of aircraft has increased, the total number of crew members of the Zeppelin has been greatly reduced due to the elimination of a large number of unnecessary personnel, and the flight wing is only more than 1,600 people, which further strengthens Zeppelin's endurance, albeit by a limited extent.

It is worth mentioning that at the beginning of Sino-German cooperation, the hull of the Zeppelin had been completed and successfully launched, and because the aircraft carrier did not have extremely strict requirements for survivability like battleships, there was no need to overhaul all aspects, only to drive to China to complete the necessary parts. And since much of the work in between didn't require a large dockyard large enough to accommodate the 30,000-ton aircraft carrier, construction could begin as soon as it arrived in Shanghai, which further saved time. As a result, the Zeppelin aircraft carrier was completed in 1939, which made Goering, who thought that the Chinese were not capable of building an aircraft carrier and did not want to have a headache over this matter and carelessly let it go east

Note 1: Most of the U.S. and Japanese aircraft carriers use wooden flight decks, although the protection is weaker, but it is easier to repair when suffering minor damage, unlike armored aircraft carriers that can only obediently go back for maintenance once they are injured, at least a month, more than a few months, and the number of aircraft carriers of armored aircraft carriers under the same displacement is much less than that of wooden deck aircraft carriers.
