On April 26, 1942, the device named "Yormangund" (the giant serpent that surrounds the world in Norse mythology) was assembled and moored over Cyprus. It was at this time that he received information that the main forces of the British Mediterranean Fleet were departing from Alexandria.

"It couldn't have come at a better time." Lin Youde muttered a sentence after reading the telegram, and then gave the order to start the "British Operation". It was named "Operation Britain" because the ultimate purpose of this operation was to "scare the British monkeys".

The German units had been preparing for this plan for three weeks, and now all the units participating in the operation were in action.

The core of the Yiqiē plan is the 603 Technical Practical Brigade, which "has rich experience in using new weapons".

**

Technical Captain Oliver frowned and sat in the airship control room codenamed Giant Country.

The whole of Jormangun is made up of three airships, two of which are connected in parallel to carry the main body, and one of which is responsible for launch control and system support.

Oliver had a large display and an entire panel of indicators in front of him, and the number of switches was too numerous for the average person to count.

He muttered one last time checking the note attached to each switch, "Send us this useless new weapon...... again"

"How can you say that," Monica glared at Oliver, "although we are testing imperfect weapons, it is because they are not perfect, so we need to test them and provide technical information for improvement and refinement. After our continuous testing, the accuracy of the remote-controlled bomb has been improved. ”

"But our final conclusion is that it is not suitable for real combat." Oliver didn't back down, and retorted loudly, "And now I bring this thing, it's just a temporary patchwork, and I haven't even done a test, and the operation manual given to us by the scientific research department is full of estimated numbers, which is very unreliable at first glance." To put it bluntly, if you launch at such a distance, you can't aim at all, right? What is the point of such a weapon? ”

"That's okay, because I wasn't going to use it to aim and shoot, Captain."

A sudden sound from behind him caused Oliver to turn his head to look behind him, and then he bounced up from his position like a spring and saluted the person who made the sound. The entire bridge of the "Giant Country" is the same for everyone.

"Relax," Lin Youde waved his hand, and then walked in front of Oliver, "Captain, our submarines and high-altitude reconnaissance planes are tracking the British fleet, and when we are done adjusting, they will shoot directly at the area where the British fleet is located." ”

"Ah, but what's the point? It's just luck to be able to hit, right? ”

"yes, luck, but it doesn't matter if you don't hit." Lin Youde gave a thumbs up and waved left and right, "The key to the entire British war is not to cause actual damage to the British, but to make the British feel that they are about to suffer losses in vain." To do this, only one of the shells we projected would have to land at a more threatening distance from the British.

"Moreover, our target is not a single ship, but the entire British fleet, it is very difficult to hit a single ship with Jörmangund, after all, we estimate that its circular probability error will be calculated in kilometers, of course, Jörmangund's bullet speed is very fast, and it is from the sky to the ground, the gravitational potential energy has been decreasing, and it is constantly converted into kinetic energy, so its bullet speed will always increase, so the accuracy is better than those guns fired from the ground."

Lin Youde said that everyone present understands that if the shell is subjected to an external force during the flight process to produce an acceleration A that deviates from the flight path of the shell, the faster the shell flies, the shorter the time to hit, and the shorter the time left for the acceleration A to change the direction of the shell, and the relative accuracy of the hit is improved.

Therefore, high-precision rifles generally have a very fast muzzle velocity, which is the reason. And increasing the weight of the projectile of a high-precision rifle is to reduce the external force from the other direction to change the efficiency of the projectile motion: the acceleration is equal to the external force divided by the mass of the object, and in the case of a certain external force, the greater the mass of the object, the smaller the acceleration, and the slower the rate of change in motion.

Jormangund used the 280 mm shells of the K5 train gun, but the muzzle velocity of the shell leaving the launcher could be fifteen times that of the K5 train gun, and Schrödinger, after a ballistic calculation, thought that it might be about three times as accurate as the K5 train gun, taking into account the effect of the firing distance.

The problem is that this result was made at a steady stop before the launch platform itself. Unfortunately, this premise is a false proposition at all, even if the airflow around the airship is stable during launch, the momentum generated during the launch will push the airship backwards.

Many people think that the recoil is generated by the combustion of gunpowder, but this is not true at all, the root cause of recoil is the conservation of momentum, when the shell gains a forward momentum, the launch carrier will gain a backward momentum, and the values of the two are equal.

So Mikoto Misaka must be a fat girl with excellent weight, otherwise she would definitely fly backwards when she fires the super electromagnetic cannon, and crash into a mess of mud on anything.

In order to counter the strong momentum of the shells, Lin Youde's men have modified the airship, adding huge stable sails on both sides, and also equipped the rear of the gun with a solid rocket jet system.

Therefore, after the Jörmangand fired, it was necessary not only to replace the coil fuse, to load the shells, but also to replace the solid rocket group set up in the tail - that was a total of fifteen solid rockets, and now the German level of craftsmanship can only build such a large solid rocket.

In order to ensure the speed of the fire, all of these replacements will be taken care of by the de-armed Flying Wizard Armor piloted by Warrior Hime.

So on the whole, Jolmangund is definitely an inefficient, extravagant weapon system.

"But," Lin Youde gave his thumbs up again, "once we succeeded in projecting a cannonball close enough to any of the ships in the British fleet, it did its job. ”

It's unrealistic to attack a ship with Jörmangund, but if there is a fleet within range, the chance of a shell landing right near a ship is greatly increased.

"Our submarine forces will deliberately expose themselves to the British before Jorman Gunde fires, so that the British will put on a ring alert formation. That's when we attacked. We just need to fire the shells at the coordinates provided by the reconnaissance aircraft, and leave the rest to probability. Lin Youde paused, "Of course, before we can do this, we have to wait for a guest. ”
