Electromagnetic weapons range.
An iceberg stands tall above the vast wasteland.
Icebergs of this kind are common on Ganymede, because there is too much water on Ganymede and the temperature is too low.
Compared with ordinary rock peaks, the lifespan of this kind of iceberg is actually very short. With the geological movement inside Ganymede and the movement of ocean currents under the thick ice layer, coupled with frequent asteroid impacts and tidal gravity from Jupiter, this kind of iceberg may be born in just a few thousand years, and may disappear in just a few hundred years.
But at least while they still exist, they are just as towering and indestructible as rocky mountains.
The height of the iceberg in front of him was over 100 meters. It was made of ice that was harder than rock. Because it was mixed with many impurities, it was pitch black and looked like it was made of steel.
Faced with such a huge mountain, the most powerful model of the eighth-generation electromagnetic cannon studied by Li Qingsong was towed by a heavy truck to a place about one thousand meters away from it.
Yes, even the largest electromagnetic cannon can be moved. This is because when Li Qingsong first designed the electromagnetic cannon, he adopted a modular design, making them self-contained and usable as long as they are connected to external energy.
This will help improve the overall reliability of the spacecraft - even if the electromagnetic cannon breaks down, it will only affect itself and not the entire system.
At this moment, this giant electromagnetic cannon with a diameter of one meter and a length of 50 meters has completed the installation and fixation work.
Compared with the first generation of electromagnetic guns, its overall mass is greatly reduced and its diameter is also greatly reduced, but the length of the barrel has not been reduced.
It is even longer than the second-generation electromagnetic gun.
This is certainly because it is the largest model, but also because in order to accelerate the projectile to a high enough speed, there must be sufficient acceleration time, which means that the barrel must be as long as possible.
Thick cables spread from the power grid and were busily connected to the electromagnetic cannon by the clones.
The ammunition bay door opened, and some ellipsoidal projectiles made with special technology and with greater penetration and lethality were poured in.
This ellipsoidal projectile is about one centimeter long and has a total mass of about 5 grams, which is comparable to some gunpowder gun bullets.
There are a lot of them, as many as 1 million, with a total mass of five tons.
After everything was checked, I pressed the charging button and a slight vibration came from the ground beneath my feet.
Li Qingsong knew that if the air density on Ganymede was higher, he should still be able to hear the low humming sound.
That's the sound of the internal equipment starting to work, and the powerful electricity being converted into other types of energy.
In just three seconds, the launch preparations were completed and the launch process began.
The next moment, a projectile automatically entered the launch chamber from the ammunition chamber.
Inside the launch chamber with an inner diameter of 90 centimeters, or the gun barrel, it was lifted up by an invisible force and suspended in the center of the barrel, and began to accelerate rapidly under the push of this invisible force.
In just fifty meters, it accelerated from its initial speed of zero to a full 15 kilometers per second!
The acceleration reached 2250 kilometers per square second! Because the acceleration is equivalent to the gravitational field, during the acceleration process, the gravity exerted on the projectile is about 230,000 times that of the earth's gravity!
If a spaceship accelerates at this rate, without considering the effects of relativity and other physical effects, it will only take it about two minutes to accelerate to the speed of light!
This acceleration is undoubtedly extremely amazing. However, Li Qingsong knows that it can only be achieved in weapons such as electromagnetic guns, and the existing technology can only accelerate materials with a mass of 5 grams at most.
Under such a powerful acceleration, the projectile completed the entire acceleration process in just about milliseconds, and then flew forward violently at a speed of 15 kilometers per second.
This speed gave it an energy of 562,500 joules. The most powerful gunpowder gun that Li Qingsong had developed previously only had a kinetic energy of 30,000 joules per bullet. The kinetic energy of this electromagnetic cannon projectile was about 19 times that!
In just one fifteenth of a second, the projectile crossed the one thousand meter distance between the electromagnetic gun and the iceberg and slammed into the iceberg.
The next moment, this iceberg, which was as hard as steel and had a pitch-black color, was hit by a bullet weighing only five grams, and a huge ice hole was directly created, just like it had been hit by a meteorite.
But this is not the end, it is just the beginning.
Only seconds passed before the second electromagnetic cannon projectile of the same mass and speed whizzed in and hit the side of the ice cave.
Then, the third, the fourth...
The fierce bombardment lasted for more than five hours until all the one million shells were used up.
If it were an ordinary gunpowder gun, firing pellets at a rate of up to 3,000 rounds per minute, it would only take a few minutes for the barrel to overheat and have to stop. But for this electromagnetic cannon at this moment, such a firing rate is just ordinary.
Because it uses superconducting technology to transmit electricity, the overall heat generation is extremely low. Even if you play for a whole day, no parts will overheat.
The dust and debris gradually dissipated as the electromagnetic cannon stopped firing. Then Li Qingsong saw that the iceberg, which had been towering and indestructible, had been cut in half.
It only has about 100 meters of height left below it. The more than 200 meters of the mountain above have all collapsed.
Feeling the powerful force of this electromagnetic cannon, Li Qingsong's heart was filled with joy.
He knew that he finally had weapons suitable for space combat.
"Electromagnetic cannons are good, but they consume too much electricity."
Li Qingsong sighed in his heart: "After more than five hours of launch, with a total mass of only five tons, the power consumption has reached a terrifying 500,000 degrees, which is almost comparable to a supercomputer.
But it doesn't matter, it's acceptable. Nuclear fission reactors have been miniaturized and can be carried on ships."
After completing the shooting test of the largest model of electromagnetic gun, Li Qingsong pulled out many electromagnetic guns of different lengths, muzzle diameters, and even projectile masses, and launched another bombardment at another iceberg.
At this moment, electromagnetic gun technology has been roughly mature. At another experimental base, Li Qingsong once again received good news that he had been waiting for for a long time.
High-speed radar technology has finally achieved a breakthrough!
