However, the testing has not stopped, as there will be live-fire artillery tests of 100 kilometers and 150 kilometers to come.

In order to thank them for sending two Arleigh Burke-class destroyers to act as spectators, Lin Feng decided to further demonstrate the performance of the first-generation railgun.

That is to say, the attack distance of the test experiment has been adjusted to 200 kilometers. I believe that the fleet commander Mike Joseph will be very happy, right?

In this regard, when the commander of the aircraft carrier fleet, Mike Joseph, heard Lin Feng's decision, his face became as gloomy as the bottom of a pot.

After all, aircraft carriers are too big and their speed is not much faster, usually only around 30 knots.

Therefore, even if the aircraft carrier is given dozens of seconds to react in advance, if there are many shells and the movement trajectory of the aircraft carrier is calculated in advance, so that it can be fired in advance, the aircraft carrier will not be able to avoid the shell attack.

Therefore, even if the super-electromagnetic gun at this time is only a first-generation model, if several of them work together, it can put the US Empire's aircraft carrier under life and death pressure.

Faced with this situation, Mike Joseph could only sullenly say those words that made him extremely ashamed.

"I declare that from now on, no one is allowed to approach the 300-kilometer range of Daxia's coastline without orders!"

As Mike Joseph said this, he knew what it meant, that they would not dare to enter the South China Sea next.

Because Daxia has built a large number of artificial islands in the South Sea. Although the area of ​​these artificial islands is not large, it is still no problem to deploy several or even dozens of super-electromagnetic cannons.

In other words, as long as a few super-electromagnetic guns are deployed on an island, they can pose a great threat to aircraft carriers and other warships.

And how big is the range of 300 kilometers?
Taking Sanya as an example, the distance between Sanya and XSQD is 325 kilometers, while the coastline of Vietnam to the west of Sanya is only 300 kilometers!

Therefore, after Daxia deployed a super-electromagnetic gun position on an island in the South Sea, the area within a radius of 300 kilometers and a diameter of 600 kilometers became a death zone for enemy warships.

Daxia has built many artificial islands in the South China Sea. After multiple islands are equipped with super-electromagnetic cannons, 80% of the entire South China Sea can be directly turned into an inland sea!

This is the importance of the birth of the A Certain Scientific Railgun, and it is also the reason why Mike Joseph looked so unhappy.

It can be said that from then on, the U.S. imperial fleet no longer dared to enter more than 80% of the South China Sea, and only dared to sail in the remaining 20%.

How frustrating is this for their super fleet that has been rampant for many years?

However, it turned out that it would not be long before they were faced with something even worse.

Because on the third day after the first generation of the super-electromagnetic gun experiment, Lin Feng finally accumulated enough experience points to upgrade the electromagnetic gun in two days!
……

Xingtu Industrial Park, in a secret warehouse next to Xingtu's fully automatic production plant.

Lin Feng looked at the first-generation railgun that had just been assembled and manufactured, which showed 8600 million experience points, and directly gave the order to upgrade it.

"Buzz!"

The first generation railgun in front of him suddenly disintegrated into metallic smoke.

Then, accompanied by an inexplicable gust of wind, a railgun with a completely changed appearance began to emerge from the bottom. This was the second-generation railgun!
At this time, the appearance of this second-generation railgun is completely different from before, and its size has become three times the original.

The most important thing is that its appearance has become a structure with three wing blades, and it is obvious that it has three high-precision radars.

And behind this is its super-long gun barrel, which is much longer than before, almost twice as long.

It can be seen from the surface that the maximum speed of the projectile fired must have exceeded 10 times the speed of sound. Because the super-electromagnetic gun is different from traditional artillery, the super-electromagnetic gun relies entirely on the Ampere force to propel the projectile to accelerate.

Therefore, the longer the barrel of the electromagnetic gun is, the more Ampere force the shell can obtain, and ultimately the speed becomes faster and faster.

Theoretically, if the barrel is long enough and the energy is sufficient, it is possible to accelerate the projectile to the speed of light.

At this time, the barrel of the super-electromagnetic gun has reached twice its original length. It can be known that the speed of this super-electromagnetic cannon shell must exceed 10 times the speed of sound, and it is possible to reach 20 times the speed of sound.

Of course, people cannot judge exactly how many times the speed of sound it can reach based on its appearance alone, and can only make a rough guess.

At this time, in addition to the three radars and the super-long barrel, the device at the bottom of this second-generation super electromagnetic gun is also quite attractive.

Because below the bottom, in addition to a device that automatically adjusts the firing direction of the electromagnetic cannon, there are also 6 independent large boxes.

These large boxes all have some thick wires, which are connected to the tail of the railgun.

Just from the surface, you can tell that this is a place dedicated to storing electrical energy, that is, a supercapacitor module.

After all, the super-electromagnetic gun is mainly composed of three parts, namely the control system, electromagnetic coil, and supercapacitor.

The electromagnetic coil is composed of two major factors: the first is the material and the second is the structure.

In terms of materials, there are pure single-walled carbon nanotube superconductors, which have perfectly solved the material problem. After that is the design structure of the electromagnetic coil.

The difference in structure of this thing will affect how much propulsion the electromagnetic coil can apply to the projectile.

For example, the coin-shaped electromagnetic coil that Lin Feng made before, if it was simply wound into a circle, the driving force it could generate was only 2.6 joules.

But the specially designed and arranged electromagnetic coils can ultimately provide 3.7 joules of kinetic energy for bullets like coins!

The same coil, due to the different coil arrangement structure, ultimately increases the thrust by nearly half. This is the charm of the electromagnetic coil structure design.

Behind the electromagnetic coil is the supercapacitor, which directly affects the firing speed and thrust of the electromagnetic gun.

Because a super-electromagnetic gun cannot be directly connected to the power grid. Firstly, the voltage is not enough, and secondly, the power grid cannot withstand such a toss.

Therefore, the railgun requires a special energy storage device, which needs to be able to discharge and charge quickly.

This also leads to batteries being unqualified, and ultimately only capacitors can meet the standards because only capacitors can discharge and charge quickly.

But even for a supercapacitor, there is no way to charge and discharge completely within one second.

This will eventually result in the super-electromagnetic gun's firing speed not being fast enough, and in order to solve this problem, the only solution is to use more sets of supercapacitors.

That is to say, your supercapacitor module will be charged slowly first, and I will use other supercapacitor modules first.

By continuously increasing the number of supercapacitor modules, we can eventually reach the limit of what the electromagnetic gun coil can withstand or the limit of the shell loading speed.

However, the number of capacitor modules of this second-generation railgun is as high as 6 groups. I don’t know how fast this second-generation railgun can fire?
With curiosity in his heart, Lin Feng closed his eyes and checked the knowledge that was instilled in him! (End of this chapter)
