Transmigrated as the Crown Prince

Everyone in the V3 cannon base was afraid that something would go wrong, so they checked it carefully several times, and the time finally reached eight o'clock in the evening.

"ignition!"

Bang bang bang bang bang! !

The V3 cannon is a multi-stage artillery with many segments connected together like a multi-segmented centipede. Moreover, there are many horizontal short tubes on both sides of the main gun tube, which are the powder chambers. When firing, the main propellant is ignited first, and then the gunpowder in the first cross tube is ignited when the cannonball just flies over the first cross tube. The other cross tubes are also ignited in sequence as the cannonball flies over.

However, as the number of gun barrel sections increases, it becomes increasingly difficult to control the timely ignition of each powder chamber. Engineers gradually discovered that the boosting effect of each gunpowder chamber was not fully exerted at all, and only a few gunpowder chambers were effective. The reason was that the ignition time of each section of the gun barrel was inaccurate, so many bombing accidents occurred.

In the end, time control was still a mathematical problem. Yannick sent Turing to help, and Turing designed a set of automatic ignition mechanical devices with little effort, which perfectly solved the ignition time problem of each powder chamber.

Now the powder chamber at the bottom of the cannon is ignited first, causing the cannonball to start moving. As the cannonball flies quickly through the powder chambers of each section, each section of the powder chamber is also ignited in time, so that the cannonball is continuously accelerated. In this way, the initial velocity of the 83-kg artillery shell leaving the muzzle can reach 1800 meters/second, and the maximum range can reach 300 kilometers.

Standing in front of the window, Kunda couldn't help but sigh as he watched the muzzle located near the top of the mountain finally eject a ball of flame after a series of explosions. "Haha, the British never dreamed of it, right?" Goebbels's broadcast was obviously a trick, saying that London would be bombed. In most people's minds, bombing meant using planes to drop bombs. It was impossible to imagine that the Germans would use this method. A super cannon for bombardment.

The assistant standing next to him also had a surprised look on his face. "Yes, the Paris artillery in the last war was amazing enough. Your Highness is really a genius. Unfortunately, if Your Highness had been born ten years earlier, I am afraid we would have unified Europe last time."

Kunda patted him on the shoulder. "Fortunately, there is still a chance, right? We won't lose this time. By the way, how many cannonballs does His Highness want us to fire?"

"No instructions."

"Then each gun will fire 20 shells first, then check the condition of the gun barrel, and then decide the firing frequency."

"I think it will work."

"I heard that the latent agents in the UK will send bullet impact points. Let's wait and see."

Ten minutes later, the correspondent came in with a telegram. "Report, this is the impact point sent back from the UK."

Kunda, who received the telegram, took a look at it, smiled bitterly and shook his head. "Tsk, as expected, the accuracy is really not flattering. The impact point of the No. 1 cannon was three kilometers away from the expected, the impact point of the No. 2 cannon was five kilometers away, and the No. 3 cannon was a bit outrageous. It was off by ten kilometers, just a little bit. It hit the suburbs. The impact points of the rest of the shells were very different."

The assistant said disapprovingly. "It's better than the Paris cannon, isn't it? After all, they have all hit the city of London. And His Highness said that this kind of cannon does not count on accuracy, as long as it can hit the city, it will be considered a success. Now ten shells have hit the city of London, it can be said We have successfully completed the tasks assigned by His Highness.”

"Haha, last time the Paris Cannon didn't consider the deflection force of the ground, and I still wondered why the fired shells always deviated from the target to the right." Kunda ordered after laughing at himself. "Keep firing, firing another 19 rounds from each gun."

"yes!"

When the first shot fired by the V3 cannon flew over London, Old John was looking at the clear night sky on his roof, smoking leisurely.

"It seems those timid Germans don't dare to come!" He picked up his luminous pocket watch and took a look at the time. It was already past 7 o'clock (Berlin is one hour ahead of London).

I threw away the cigarette butt in my hand and was about to turn around and go downstairs when I suddenly heard a strange noise coming from the distance. Old John couldn't help but stop and look in the direction of the sound, trying to identify what the sound was in the air.

He swore that he had heard a similar sound before, but unfortunately he was old and his brain was not very bright, so he couldn't remember it for a while.

The voice became clearer and clearer, and Old John felt that the hairs all over his body stood up involuntarily.

The fear deep in his soul finally awakened his memory. This was the sound that he had been unable to adapt to for several years. This sound, somewhere between the bass organ in the church and the exhaust of the steam pipe, was what made him feel that way. Hiding in the trench, he almost peed his pants at the sound, that... terrifying sound of large-caliber artillery shells piercing the air! !

"Damn, this is shelling!!"

Old John was startled by his answer, shelling? !How could the city of London be bombarded? Didn’t the Germans want to bomb London with planes? !How can their cannons have such a long range? !Is it possible that the Germans have already landed in Britain? !

A series of unanswered questions popped up, and he couldn't care less for a moment. There were several cracking sounds in the air, there must have been eight or nine.

It was obvious that the Germans had more than one gun.

Listening to the successive explosions in the distance, Old John was so frightened that he ran downstairs and took his family to hide in the air-raid shelter dug during the last war.

"What's going on? Didn't the Prime Minister promise not to let a bomb fall into London?" Hearing more than one explosion outside, the family was frightened and at a loss. At noon today, Prime Minister Churchill also swore on the radio that he would never let a bomb fall on London.

Old John shook his head palely. "It's not a plane bombing, it's an artillery bombardment!!"

Everyone was even more shocked. "What? The Germans are coming?!"

After all, Old John is a veteran who participated in the last time and is still very experienced, he analyzed. "No, it was probably the Germans who shelled from across the coast. Maybe they built the 'Paris Cannon' again."

At this time, two men in janitor costumes were hiding on the top floor of Big Ben, one of the famous landmark buildings in London. One of them was looking into the distance with a telescope and reported the impact point, while the person next to him kept pressing the button. Radio keys.

After the ten impact points were sent, the operator asked while putting away the radio. "How far is the launch site from here?"

The strong man holding the telescope replied. "The launch point is in the Calais area, at least 150 kilometers away from here."

"Isn't that the Paris Cannon?"

The strong man said proudly. "The Paris Cannon is nothing. I heard that the shells this time can hit 300 kilometers."

"Ha!" The dispatcher was shocked. The last time the Paris cannon was shocking enough, this time the range of the cannon was more than twice that of the Paris cannon.
