"Boom!" with the artillery commander's firing, a huge shelling came.

In the gun bore, the striker strikes the steel bottom semi combustible cartridge. The high-energy propellant in the cartridge is fired in an instant. It burns hot inside the gun barrel to generate high-temperature and high-pressure gas.

For tank guns, the more the charge, the greater the launch energy. At the same time, it also means that the pressure on the gun barrel is greater. If the gun barrel cannot bear it, it is the risk of blasting.

A gun barrel seems to be made of steel, but it reflects the metal smelting level of a country.

After ten years of turbulence, the level of metal smelting in Han country has not made any progress. Just like the original large-scale steel smelting, on the surface, the output of steel is hundreds of millions of tons, but there is no high-quality steel.

Now, the equipment imported from NiuGuo can meet the needs of gun barrel.

The first is electroslag remelting steel. As the name suggests, this technology uses current to melt metal and re smelt. In the smelting process, slag falls below and high-quality steel ingots fall above.

This is the first step in manufacturing high-quality gun barrel, that is, advanced steel, and then the gun barrel process. The barrel self tightening process is adopted to increase the compactness of the gun barrel and further improve the pressure carrying capacity of the gun barrel.

The last is internal chrome plating, which increases the friction life.

The previous 59 tank guns were bald when they fired more than 100 shells, while the imported L7 linear bore guns had a barrel life of hundreds or even thousands, which was used by others.

Now this kind of tank gun can easily bear the existing chamber pressure. Under great pressure, the warhead in front accelerates forward quickly driven by the sabot.

If it is a linear bore gun, it begins to rotate under the action of rifling in the gun barrel. However, now it is a smooth bore gun without any rifling inside. At the same time, it is also a newly developed projectile, with a slender core, which flies driven by the sabot.

Yes, it's thin and long.

The caliber of the tank gun is 120 mm, while the diameter of the bullet core is only 38 mm, which means that if there is only a bullet core, the gun barrel cannot be filled at all. If the gun barrel cannot be plugged, the gas just burned by the cartridge will be wasted.

Therefore, outside this armor piercing projectile, there is a sabot, which is consistent with the caliber of the gun. In this way, the sabot gallops in the gun barrel with a core.

Almost instantly, they were pushed out.

At the moment when it was pushed out, the hot flame inside followed out of the gun barrel. The high-temperature and high-pressure gas violently compressed the outside air and made a terrible shelling sound.

Boom!

At the muzzle, a big fireball with a diameter of one meter appeared. The big fireball was rapidly spreading around and becoming larger. At the same time, a black smoke was steaming above the fireball.

The firing of tank guns is so spectacular!

In the flame, the core flew forward at a speed of 1650 meters per second. The sabot on its body became two halves and flew away.

The so-called shelling refers to these two sabots.

After leaving the barrel, the sabot fell off and it had completed its mission.

The slender core, like an arrow, flies forward. Its tail opens four small wings.

Ordinary shells are stabilized by rotation, and the shells flying out of this smooth bore gun cannot rotate at high speed, so they need to be stabilized by the wing.

Ivanov was stunned when he saw the fire opposite. It's impossible. How is it possible? This is beyond his level of understanding.

2500 meters, at a distance of 2500 meters, the other party actually opened fire!

In contrast, almost no tanks in bear country can hit when firing from a kilometer away! How is this possible? The other party must be shooting blindly.

Yes, that's it.

The other party just wants to bluff. If he can really hit the target at a distance of 2500 meters, he will blind his eyes!

Just when he swore such a poison, the bullet core had come with a roar.

This distance takes less than two seconds, and when it aims, it has estimated the advance. Anyway, the target travels at a constant speed, and the fire control system can accurately calculate it. Even in a real battle, the other party needs reaction time to brake or speed up after discovering that its own side fires, and it can still hit to a great extent.

With great speed, the bomb core hit a 59 tank in the first row in front. At the moment of impact, the whole tank trembled.

Hit, hit?

Although the mass of the bullet core is very small, its speed is very high, and its huge speed brings huge energy. This is the same as when a bullet hits the human body, people will retreat under the impact of the bullet. When the tank is hit by such a collision, the whole body trembles.

At the same time, the pit began a hard fight.

This kind of core is a tungsten core with a steel sleeve on the outside. During the impact, the core began to move forward.

In front of it was the head of the turret of tank 59, the thickest armor part, and the bullet core, like a wedge, plunged into it.

In the process of penetration, the speed of the bullet core is also decreasing. If the speed is reduced to zero and still does not penetrate, the armor penetration fails. If the bullet core has drilled in when there is still speed, the armor penetration is successful.

Therefore, the pits are slender.

Drilling a small hole is much easier than drilling a large hole. The previous armor piercing shells were of the same caliber. In the late World War II, the sub caliber armor piercing shells were invented, and the armor piercing ability immediately went up to a higher level. This sub caliber means that the armor piercing core is smaller than the caliber of the fire gun, which is similar to the current shelling armor piercing shells.

At the same time, this is a hard fight. Naturally, the bullet core should be made of the hardest metal! Tungsten alloy armor piercing projectile is a common way.

At this time, as the core began to drill at a huge speed, the temperature of the friction part exceeded thousands of degrees, and the armor in this part began to melt and form iron slides one by one.

Then, the warhead is a loose, it has drilled in!

Is there any doubt about using 120 mm shell piercing shells to hit 59 tanks? As long as you don't get shot by the turret in the shape of avoiding bullets, the breakdown is a matter of minutes.

Moreover, after the breakdown, its storage speed is still three-quarters!

After all, the worst armor piercing ability of others is 500 mm. It's easy to catch a turret of more than 100 mm!

The direction of the warhead hardly changed and continued to move towards the back.
