Transmigrated as the Crown Prince

“…We are facing an unprecedented crisis, which is a difficulty we have never encountered before…but we have the ability to solve the current difficult situation, and our military can protect the safety of our citizens and protect our homeland…Freedom and democracy The United States of America, the American people who advocate freedom, will never surrender... We will not let our democracy go backwards! Never!..."

President Wilkie delivered an impassioned speech, but as soon as he walked out of the broadcast room, his secretary reported news to him that surprised him. "Mr. President, the Germans have sent out another bomber group. They will invade our country's airspace in more than four hours."

"What?! How dare they come?!" The Germans stopped bombing the United States after their own XP-67 high-altitude fighter jets entered service. Why are they coming again now? !

"I'm not sure about this." The secretary naturally couldn't answer these questions, and President Wilkie hurried to the combat command room. "Commander Arnold, how come the German bombers dare to come?! Our fighter jets can be dispatched at any time, right?" He even speculated that it was because his own fighter jets collectively malfunctioned that the Germans dared to take advantage of the situation.

Commander Arnold looked a little serious. "Mr. President, I can't figure out why the Germans sent out another bomber group. Did their bomber ceiling increase?" Our XP-67 high-altitude fighter could barely climb to 14,200 meters, and it had almost no maneuverability. In other words, if the flying altitude of the German bombers can continue to rise, then there is really nothing they can do. "Our fighter jets have no problems and can take off for combat at any time."

"No way? Is it possible that the German bombers can fly to an altitude of 15,000 meters?" Is this too exaggerated? How did they do that?

Just as everyone was talking about it, news came from the Atlantic Fleet Command that a German fleet was heading straight for the east coast.

"!!" It's true that misfortunes never come singly. Last time, these guys almost destroyed most of Boston into rubble. This time, I don't know where they are targeting? But their navy can only continue to be a coward, unable to respond to the challenge.

However, compared to this fleet, the bomber group poses a greater threat. Commander Arnold ordered the XP-67 high-altitude fighter group to prepare for battle. Once the German bombers enter our own airspace, they will immediately take off and shoot them down!

Four hours later, when the German bomber group was about to enter U.S. airspace, a fighter group taking off from the German fleet aircraft carrier merged with them to escort them.

Soon, they encountered a group of XP-67 high-altitude fighter jets that came to intercept.

Looking at the large group of oncoming aircraft from a distance, the US fighter pilots couldn't help but exclaimed.

"Oh my God, they have fighter jet escorts!"

"Their fighter jets fly higher than the bombers! That's a liquid-cooled engine!" The cylinders of the air-cooled engine are arranged in a star shape and arranged in a circle around the crankshaft. It looks short and thick in appearance. The multi-position V-shaped arrangement or X/H-shaped arrangement of the liquid-cooled engine looks long and thin in appearance; therefore, it can be distinguished at a glance.

"Liquid-cooled engine?" Commander Arnold in the combat command room frowned slightly. Previously, all fighter jets mounted on German aircraft carriers had air-cooled engines. Why did liquid-cooled engines appear today?

Almost all carrier-based aircraft on World War II aircraft carriers were air-cooled, with few liquid-cooled models (the British Sea Spitfire was one of the few liquid-cooled ones). Because liquid cooling requires high-purity coolant, the liquid cooling system will inevitably leak. Although it will not cause a malfunction, the liquid level must be checked before each takeoff to replenish the coolant. It is necessary to reserve additional high-purity coolant on the aircraft carrier. Serving the liquid-cooled engine will affect the speed of carrier-based aircraft dispatching again, which is really unnecessary trouble. Coupled with the shortcomings of liquid-cooled engines, relatively sturdy air-cooled engines are naturally more popular among aircraft carriers.

"Did the Germans specially create a liquid-cooled type to deal with our high-altitude fighter jets?"

For piston fighters during World War II, the pursuit of speed and altitude was the constant purpose. The competition between the two types of engines, liquid-cooled and air-cooled, is naturally inseparable from the pursuit of speed and height. Increasing horsepower and reducing drag are the only ways to increase speed, and both liquid-cooled engines have advantages. Regarding altitude, the air at high altitude is thin, and the power of the piston engine will be reduced too much, making it unable to fly higher. Turbocharging or supercharging can increase the air intake volume, increase the air intake density in disguise, maintain power, and increase the ceiling of the fighter jet. It is difficult to apply turbocharging to air-cooled engines because each cylinder has independent intake and exhaust, and a compressor or exhaust gas turbine needs to be installed on each cylinder. The structure is complex and heavy, and the gain outweighs the loss. The liquid-cooled engines are arranged in a row, and the intake and exhaust can be unified with a converging device. A turbocharger or supercharger system is enough, with a simple structure and high efficiency.

Commander Arnold really guessed correctly. In order to deal with American high-altitude fighter jets, the German army specially rushed to build 20 liquid-cooled fighter jets and put them into battle.

As a result, the XP-67 high-altitude fighters, which had almost no maneuverability at an altitude of 14,200 meters, faced the German fighter jets swooping down from overhead. They could only be beaten and had no power to fight back. Soon, all thirty XP-67 fighter jets were shot down.

"Oh God!" Commander Arnold's face turned black. These were all the high-altitude fighter jets that he had managed to gather together! The enemy's entire army was wiped out without even being able to shoot down a single bomber! This is too frustrating!

Then the news that the German bombers separated made everyone in the command room look extremely ugly. The Germans are probably going to drop those damn carbon fiber bombs again, and the Northeast Industrial Zone, which has just recovered, is probably going to be paralyzed again. What's even more depressing is that they are completely helpless about it.

"Mr. President, let all cities cut off power." These carbon fiber wire bombs are simply unsolvable. So far, they have not found an effective countermeasure. They can only use the not-so-smart method of cutting off power. It is indeed a stupid method, because even if the power is cut off, those carbon fiber filaments will not be cleaned for a month or two, which means that the industrial area will also have to stop work for a month or two.

President Wilkie could only nod helplessly and ordered cities in the Northeast to cut off power.

The shrill sound of air raid sirens sounded over various cities.

People in the city hurried to the nearest air raid shelter.

"What's going on?!" In the broadcast just now, the president made an impassioned pledge to protect the country and protect the safety of the people. Why did the air defense siren sound in less than half a day?

The people next to me were angry. "What else could be going on? It must be the Germans bombing again."

"But didn't President Wilkie just say..."

"Every president talks like farts. If you believe them, that's called naivety."
