Anyway, there is only one gun position in today's shooting range where they are shooting, so there is no need to worry about accidental injury, otherwise, you must be careful when you go to see the target, after the establishment of the exercise range here, there are accidents every year, of course, the troops are already in danger, and there is such data as casualty indicators at all.

Now, several people got on the motorcycle, jolting towards the target, no one spoke, and there was a kind of urgency in their hearts, go and see, go and see!

This is the first time to ride a motorcycle, especially, if Qin Zhenhua is in normal times, he must feel it beautifully, and now, he is also full of urgency in his heart, how is it?

The breakdown must be the breakdown, so, is there any excess potential? How accurate is it?

The inside of his ears was still rumbling, and in his head, all kinds of thoughts kept popping up, making Qin Zhenhua feel for the first time that his brain was a little insufficient.

Finally, the partiality came to the front of the target, and the target reporter, who was originally squatting in the bunker under the target, also came up and said to several people: "Our shell is too evil!" ”

I couldn't believe his eyes, the target was a standard homogeneous steel, one hundred and fifty millimeters thick, because their original armor-piercing shells could only penetrate a hundred millimeters, so it was said that the shells could be properly left on the target.

What now?

The target of homogeneous steel has already appeared a hole, the front is relatively large, showing a molten state, and you can even see that there is an iron chute underneath, and the thin rod of the armor-piercing projectile has completely passed through this target, although a relatively small bullet hole has been left in the back, but the warhead has not been retained.

That is, the purpose of a perfect breakdown of armor was achieved!

If it is pierced into the target, it is not powerful, the goal of this armor-piercing projectile is to penetrate the armor, and then drill into the inside of the tank, as long as it bounces back and forth a few times inside, it can stir up the inside of the tank.

When the warhead collides with the target, the high temperature even melts the surface of the target, and you can see that the distance from the reticle in the center of the target is about ten centimeters, and this accuracy is already quite high!

"Keep this target, waiting to be reported to the higher-ups." Bi Liansheng said: "Now, change to a target with a thickness of 200 millimeters, and let's continue the experiment!" ”

Originally, Bi Liansheng didn't attach much importance to this mission, and it was only because of Luo Ronggen's relationship that he came to participate in person.

He knows the performance of the Type 73 100mm smoothbore gun well, and it will definitely not be as unnatural as it is now!

And now, just by changing the warhead, a qualitative leap has been achieved, which is of great significance to the entire army!

200 mm thick, can it be penetrated?

Qin Zhenhua's heart at this time was also extremely excited, father, there is no problem with your design, the shell just now has been successfully launched, there is no explosion, and the performance can be improved a lot!

That accident was not my father's responsibility at all, but there was another reason, and for this reason, I went back and began to investigate!

In the process of assembling the second shell, Bi Liansheng became serious and observed Qin Zhenhua's operation, and at this time, he finally saw the doorway.

"This warhead of yours looks so thin!"

"That's right, according to the latest theories, if you want to get higher armor-piercing capabilities, you have to do it by increasing the length-to-diameter ratio of the warhead." Qin Zhenhua said: "The thinner and longer the warhead, the stronger the armor-piercing ability, and the diameter of my warhead is only half the thickness of the original warhead." ”

The armor-piercing shells of the Soviets are all thick and large, and they look like a small rocket when they are carried, thick in the middle and thin on both sides, I don't know what they think, is it for aesthetics? Or aerodynamic considerations when flying out?

If nothing else, just a simple long pole with a pointed head, just like a javelin, is enough, and the tail has a springy wing to maintain stability, which is enough!

"I'll shoot this shot." After re-aiming accurately, Bi Liansheng personally pressed the trigger, and at the moment when the cannon fired, he opened his mouth, which is one of the basic movements of artillery, which can balance the internal and external differences of the eardrum and prevent the eardrum from buzzing.

"Target reporter, report the situation." After Bi Liansheng made the call, he took the wireless telegraph and continued to talk to the other side.

"Report, our target, has been penetrated again!"

What the?

Two hundred millimeters! The 200-millimeter target was actually penetrated? What a cannonball this is?

Back then, in order to tap the potential of 85 mm, a factory developed a "cylinder-type tail stabilized micro-rotation armor-piercing projectile", which only hit the armor-piercing ability of 120 mm, which is already a limit, and now, this shell, which looks simpler in structure, actually fights so strongly?

The partiality moved to the front of the target again, and looked at this thick, homogeneous steel target, which was completely pierced and came out with a big hole, which was absolutely impossible before.

Only this time, the potential of the warhead was almost gone, so, after passing the target, it flew more than a dozen meters and fell.

"Qin Zhenhua, you have solved a big problem for our troops!" Bi Liansheng sighed and said: "If we had it back then, why should we be powerless in front of the T-62 tank." ”

The T-62 tank, the turret in front of it, was 220 mm thick at its thickest part, and at that time all kinds of anti-tank weapons were put on it together, but there was no way to take it.

Now, finally, we have something good on hand!

Although it looks almost hot now, this warhead was originally designed for the 69 tank, the tank gun of the 69 tank, the bore pressure is higher, and the speed of going out is faster, so the penetration depth will definitely be more, and it can definitely be done!

"This design is exactly according to my father's design." When Qin Zhenhua said this, the volume was not high, but his heart was trembling violently.

Father, your design is perfectly fine! Moreover, this is not the limit, with 69 slips on 100 tanks, the armor-piercing capacity can properly reach 250 mm!

Moreover, this is only a steel core, if you apply to the superior to get a denser tungsten alloy, the armor-piercing ability can also be improved by a section, reaching 300 millimeters, which is no problem at all!

Father, you are the best tank designer!

Qin Zhenhua closed his eyes, and in his mind, the figure of his father appeared, because his father was usually busy with work, so Qin Zhenhua couldn't recall the smiling face now, only the back was recalled.

It's not his design problem, then, it is likely to be in the processing, especially this kind of complex shape of the butt, processing requires a high degree of precision, is it because the accuracy of the processing is not enough, so it finally leads to the explosion of the chamber?

If you can find the shells that were processed at that time, you will be able to solve the mystery!

Luo Ronggen patted Qin Zhenhua's shoulder, as if to comfort him, at this time, Luo Ronggen's eyes were also moist, if Lao Qin was still there, how good would it be?

At this moment, in the distance, a 212 jeep was speeding up on the shooting range.
