"The temporary solution is to install the b-109 on an engine that can perform performance over 11,000 meters," said Kesseling. "The aircraft is codenamed b-109h. Compared with other models of b-109, it improves the aerodynamic shape and increases lift. At the same time, it also has a supercharger and injection combustion aid device specially designed."

The air at high altitude is thin, and the output of the engine without a special supercharger will drop rapidly when it reaches a height of 10,000 meters. In order to increase the lift of the aircraft, the aerodynamic appearance must of course be changed accordingly.

In addition, because Germany has a leading advantage in fuel injection systems, it has developed an injection combustion-aided device for the engine to "take drugs" and temporarily increases the engine's power by injecting water and ethanol (the cost is to shorten the engine's life). This method has now been used on b-109h.

However, one advantage must have one disadvantage. Superchargers that can fly high altitudes are not easy to use in medium and low altitudes, and the aerodynamic appearance that focuses on lift is often not conducive to flexibility. Therefore, this b-109h is a dedicated high-altitude interceptor, and it cannot exert its power when it reaches high altitudes.

But this is nothing. Aircraft in World War II were divided into high altitude and low altitude. However, the b-109h was changed to aerodynamics and engine superchargers, but they could not change the problem of short legs. Because this aircraft was originally small, the fuel it could carry was naturally limited. Moreover, superchargers suitable for high altitudes were often heavier and larger in size, which was even more unfavorable for increasing the range.

The small range is not only not conducive to the b-109h acting as a high-altitude escort, covering Germany's high-altitude bombers against the United Kingdom, but also limiting its cover range and air stagnation time, so this is just a temporary solution.

"There are two final solutions," Marshal Kesseling continued, "One is the jet solution. The turbojet engine's inhalation method is different from that of the piston engine, and it is easier to adapt to high-altitude and oxygen-deficient environments. Moreover, the speed of the jet aircraft is much faster than that of the piston aircraft, which is a very ideal solution. Currently, we have two types of jet aircraft that have entered the prototype stage, belonging to Messerchmitt and Henkel. Among them, Henkel's prototype is relatively fast and can be tested in April at the latest. The jet engine jointly developed by BM and Folk Company used by Messerchmitt has not yet been completed, so the first flight time may be postponed until the end of the year."

Henkel's plan is the he-280, which is relatively fast and has an engine. The Messerchmitt's plan is the famous me-262. Because the strength of Messerchmitt's company cannot be compared with Henkel's company and does not have its own engine, although the prototype was built, there is no engine available for use.

"As for the second plan, it is the turbocharged engine plan of Folk," said Marshal Kesseling. "The turbocharger developed by Folk has been successfully tested in the Folk D31 aircraft. However, the Folk D31 is too big and too bulky, and is suitable for being a bomber rather than a fighter. Therefore, the Air Force technical experts recommend integrating the Folk turbocharger into the -190, but the -190 fuselage is too short to install the Folk turbocharger, so major improvements are needed and should be completed before the end of the year."

The Luftwaffe likes the -190 so much that it almost treats it as a "treasure of air combat" and doesn't even look down on other new piston aircraft. However, it makes sense for them to do so. Too many models are not conducive to large-scale production.

According to Marshal Kesseling's plan, in the future, the Luftwaffe fighter jets will transition to the Folk Zero medium-low altitude and the -190 series high-altitude and medium-high altitude (different sub-series need to be used to hit different altitudes), and the jet fighter jets will act as the final combination of killer weapons.

In addition, the Luftwaffe and Naval Air Force have now proposed a plan to change the -190 into a fighter bomber and carrier-based aircraft. They are even preparing to continue to improve the -190 into a "final plan" for piston fighters.

“How many b-109hs ​​are ready now?”

Hessman could probably guess what the UK and the United States were trying to make. Now, seeing the Mediterranean situation is in a hurry, the dignified formation cannot be defeated. So he wanted to massacre civilians to attack Germany and scare the European people at the same time.

"There are currently 10 squadrons ready, and there are 5 other squadrons undergoing training in high-altitude combat, and they can be put into combat at the latest by the end of February."

Hessman nodded and felt relieved. The 15 squadrons were 240 b-109h that could be put into combat. If there were not too many b-17s invading, they could deal with it.

Moreover, Germany will not only be beaten but not fight back. Now Folk has successfully developed a turbocharger, and BM has another 18-cylinder BM802. High-altitude high-speed bombers are not a problem for Germany.

As long as you take over the Middle East and have enough oil and non-ferrous metals supply, whether you are bombing or logging directly, you can solve the small trouble of the British mainland that hinders European integration.

As for how to deal with the last *oss of the United States, it depends on whether Japan is willing to cooperate with the invitation letter issued by Italy to invite the Japanese Military Observatory. With Hessman's intervention, he specially stated that the commander of the Joint Fleet, Irosaki Yamamoto, was invited to come. Hessman also wrote a handwritten letter to Japanese Navy Minister Fushiro Oikawa, specifically introducing the situation of the Scapa Bay air strike and the Eastern Mediterranean naval battle.

...

Wu Jungang, the flagship of the Japanese Navy Combined Fleet, "Nakamen".

After receiving the invitation letter from the Italian Embassy and the handwritten letter from Hessman, General Koshiro Oikawa immediately sent his subordinate official Toyota Sashijiro to arrive at the Nagatomon, which was anchored in Wujun Port.

Hessman's letter was written in English, and all Japanese Navy officers were proficient in English and could understand it without translation.

Yamamoto Iroku read it very carefully, and read it word by word twice before gently putting the letter paper on his desk.

"Yamamoto, this German Field Marshal also proposed a sneak attack on Pearl Harbor, which coincides with the suggestions you made to the Navy Minister Oikawa on January 7."

Toyota Sadajiro looked at Yamamoto with a slightly frown and said with a smile.

He is also a pro-German element in the Japanese Navy. Japan joined the German-Italy Steel League in September 1940, and he also made a contribution.

Inspired by the Scapa Bay bombing and the Toulon incident, Yamamoto Iroku began to imagine the surprise attack on Pearl Harbor. On January 7, he wrote to the Navy Secretary Iokawa, proposing the idea of ​​a surprise attack on Pearl Harbor.

"Martyr Hessman also proposed the same idea, and he also carried out a successful surprise attack..." Yamamoto Iroku smiled bitterly, "Maybe some people in the United States will think of the same way?"

"Yamamoto," Toyota Satojiro laughed and said, "The United States does not have Zero aircraft, and their naval training is slack, so it cannot be compared with us. The air strike against Pearl Harbor will definitely succeed regardless of whether it can achieve a surprise attack."

Yamamoto Izuru nodded. Toyota Sashijiro said it right. The US Navy is relatively lax now... No, it should be said that the entire United States is relatively lax, so the surprise attack can most likely be successful.

However, even if it successfully attacks Pearl Harbor and paralyzes the Pacific Fleet, it will at most win Japan a strategic window of 6 to 12 months. In the view of Iroku Yamamoto, it is not something that Japan can do.

This depends on Germany to fight! If Germany is defeated by Britain and the United States, then Japan will not be able to fight anyway.

However, judging from the current situation on the European battlefield, Germany seems to have great hope of victory.

"As long as Germany can conquer the Middle East," said Satojiro Toyota. "Our empire will take Singapore and open up Malacca, and then we can join India with both sides. The German, Japanese and Italian steel alliance will be unbeaten!"

He paused and said, "So Minister Oikawa hopes that Yamamoto can go to Italy in person and interview Marshal Hessman about joint operations."

Yamamoto Iroru glanced at Toyota. In fact, he knew that Oikawa Fushiro was not in charge. In fact, the second official Toyota Sashijiro was in charge of the Navy. Therefore, the one who wanted him to go to Europe to meet Hesman was actually Toyota himself.

"So what request does Oikawa want our official to make to the Germans?" Yamamoto Iroku knew that Toyota came here in person, so he must have been "face-to-face". However, Toyota's qualifications were not as good as Yamamoto and his military rank was lower, so he naturally had to speak in the name of Minister Kawa.

Seeing Yamamoto handing the steps, Toyota Sashijiro smiled and said, "There are some conditions. Minister Oikawa hopes that Germany can provide the technology of the ju88 bomber... This kind of aircraft is very powerful in attacking ships and can conduct dive bombing at a 60-degree angle. If the Imperial Navy can be equipped in large quantities, it will be conducive to establishing a defense circle against the United States.

Second, Minister Oikawa also hopes to jointly develop the next generation of Zero Fighter and Type 99-type ship bombers with Germany. He also hopes that Germany can transfer the most advanced engine technology to us, which is also necessary for the Empire to maintain long-lasting operations.

Third, Minister Oikawa also hopes that Germany can send some ace pilots with practical experience to Japan as instructors in order to provide intensive training for our carrier-based aircraft pilots. It is best to allow Japanese carrier-based aircraft pilots to fully understand the real air combat and the characteristics of British and American fighters before going into battle.
