It can be said that everyone at this time looked at each other in confusion, thinking that the performance of the second-generation super-electromagnetic gun developed and designed by Lin Feng was a bit exaggerated.

It is so exaggerated that it is not suitable for use in this era, but should be used in the future interstellar era.

Faced with such exaggerated facts, how could they not think it was too crazy?

Of course, although they thought Lin Feng was crazy, they had to admit that they were quite curious.

I am curious about the destructive power of this 25 times faster-than-sonic shell and whether it can sink an aircraft carrier with one shot.

However, the fact is that they are destined to never know the truth, because Daxia has no way to use an aircraft carrier as a target ship for test firing to verify the strongest power of this second-generation super-electromagnetic gun.

However, people's attention soon shifted away from their curiosity about the maximum power of the railgun.

Because the next major upgrade that Lin Feng introduced left them speechless.

"We just introduced the speed of the railgun's shells. Next, we'll introduce the automatic reloading system, which is the speed at which the shells can be fired continuously."

At this point, the projection screen behind him and the screen in the live broadcast room turned into a speed comparison chart of continuous artillery fire, without any internal structure diagram.

After all, the internal structure is confidential. Once researchers from other countries see it, it will greatly speed up the development process.

So at this time, people and scientific researchers can only roughly guess the principles and internal structure based on the appearance. They will never know whether the real situation is like that.

“10倍音速240发每分钟，15倍音速120发每分钟，25倍音速40发每分钟？”

The secretive agencies of the American Empire who were watching the press conference through the live broadcast room looked at each other in bewilderment.

"Damn, is this really just a railgun?
The firepower density of just one electromagnetic cannon is comparable to that of an entire battalion, right?!"

The people in the conference room looked at the parameters above and felt crazy. After all, this was a shell with a speed of at least 10 times the speed of sound.

When the speed of an object reaches 10 times the speed of sound, even a ball of water will have huge kinetic energy and terrifying power.

At this time, the thing that reached a minimum speed of 10 times the speed of sound was not a ball of water, but a piece of stainless steel with a mass of 124 kilograms!

Which tank or battleship can withstand a single shot from it without being deformed? Which tank or battleship can avoid being hit with a big hole?
Moreover, the firing speed of this second-generation super-electromagnetic gun can reach an astonishing 10 rounds per minute when it is in 240 times the speed of sound mode!

This means that a single second-generation railgun is a terrifying harvester!
A single second-generation electromagnetic gun could potentially destroy an aircraft carrier or even an entire fleet.

Of course, the prerequisite is that you can intercept other people's attacks on the second-generation railgun.

After all, while you are firing at others, others are also sending fighter jets or missiles to attack you.

However, this problem has obviously been taken into consideration by Lin Feng, which is why the so-called "ground-air-space integrated defense system" came into being.

So after Lin Feng introduced the firing speed of the second-generation super-electromagnetic gun, he quickly came to the most critical core part of the 'ground-air-space integrated defense system', which was the shocking guided artillery system.

"Okay, that's enough about the firing speed. Next, I'm going to introduce the guided artillery shell system."

When Lin Feng said this, the image on the projection screen behind him suddenly changed, and a picture of the shape of a cannonball appeared.

At this time, the appearance of the shell is somewhat similar to that of a missile, and it also has tail fins at the tail, but there are two adjustable tail fins, not four.

After all, the simpler the structure, the less likely it is to make mistakes, so this guided artillery shell only has two tail fins. "As you can see, this is a guided artillery shell, and it also weighs 124 kilograms.

Its appearance is similar to that of a traditional missile, except that it lacks two tail fins. However, it is not a real missile because it cannot spray gas.

However, our guided artillery shells do not require gas injection.

After all, our super-electromagnetic gun can accelerate the shells to a minimum of 10 times the speed of sound and a maximum of 25 times the speed of sound.

Under such circumstances, the kinetic energy of our artillery shells is completely sufficient, and even the amount of high explosive is several times that of missiles of the same size.

After all, traditional missiles need to be loaded with a large amount of chemical substances inside, which can generate huge thrust through chemical combustion reactions to propel the missile forward.

Since our electromagnetic gun shells don't need to do this, they can naturally load more high explosives and produce greater destructive power."

After hearing Lin Feng's words, everyone at the scene nodded slightly in approval.

It is believed that the shells fired by this electromagnetic gun will indeed be more powerful than missiles of the same size.

After all, let’s not talk about the terrifying kinetic impact brought by the shells being accelerated to 10 times, 15 times, or 25 times the speed of sound.

Just because it can carry more high explosives, the more high explosives you load, the final explosion power will naturally be far greater than that of missiles of the same size.

"Of course, the power of the shells is not the point, the point is our guided shell technology.

I believe that the guided shell technology alone is the most important and core function of our second-generation electromagnetic gun."

At this point, a short video of a sailboat gradually emerging from the sea appeared on the projection screen and live broadcast screen behind Lin Feng.

“As you can see, the sails first appear, and then the boat gradually emerges.

This is because the earth is an ellipsoidal sphere. When the distance reaches a certain range, if it is the direct-fire shells used by the first generation of electromagnetic guns, it actually has no effect on enemy ships at ultra-long distances.

Because the earth is an ellipsoidal sphere, when the distance between the enemy ship reaches a certain distance.

For a railgun that can only fire straight ahead, there is no difference between the enemy ship and the one under the sea, so it can be fired at with one shot.

In the end, the shells will hit the bottom of the sea, wasting materials and energy. On the contrary, guided shells are different.

The biggest advantage of guided artillery shells is that their direction can be adjusted to achieve a precision-guided effect.

To what extent can this precision guidance effect be achieved?

It can easily achieve the effect of a precision-guided strike on a room hundreds or even thousands of kilometers away!
Of course, if the target of our guided artillery shells is very close to the launch point, there is no way to attack the rooms on the other side of the building.

However, with its powerful kinetic energy of a minimum of 10 times the speed of sound and a maximum of 25 times the speed of sound, and a high-explosive charge that is several times that of a missile of the same size.

Everything is equal for all. No matter how big a building is, it will collapse after being hit by a few shells.

Therefore, the fact that guided shells cannot turn freely at close range like missiles is not a big disadvantage. (End of this chapter)
