Moreover, this is only the initial penetration depth, with the continuous development of technology, a series of new armor-piercing bullets can be developed, so that its penetration depth can be further increased.

A penetration depth of 500 mm, in this era, is enough to be proud of all tanks, and even the threat of tank troops for a long time to come, there is no need to worry, if it is to tap the potential, to 700 mm, the scene is simply unimaginable!

Xie Huimin looked at everyone's expressions and knew that he had succeeded.

For comparison, the tanks of the Soviets, with 125 mm barrels, so what?

The one they got over must have been tested, just like a certain country in the desert in the current fierce war, although there are T-72 tanks, but they use the monkey version of the armor-piercing projectile, and the armor-piercing ability is only more than 200 mm, which is not even as good as a 105 mm tank gun!

So, do you need to talk about it? Choose your own 120mm tank gun and you're done!

In fact, no matter what the caliber is, now and in the future, all tank guns will definitely be produced from the Second Machine Factory, but the Second Machine Plant has been studying the 120 mm caliber for so many years, and in their eyes, this tank gun is like their child, and they naturally hope that this tank gun can thrive!

From scratch to develop a 125 mm tank gun, they had to give up the 120 mm tank gun, this mood can be found from the people of the Coal Province Diesel Engine Plant, they gave up their own development of the X150 engine for several years, in favor of the 150HB diesel engine of a machine factory, the depression in their hearts can be imagined.

Xie Huimin made a systematic report on the tank gun he had developed, and also showed the future prospects, and almost everyone present had a stunned expression.

"So, we strongly recommend, on our third-generation tanks, to choose this 120-mm tank gun as a standard tank gun." Xie Huimin said.

At this time, Xie Huimin was full of confidence.

"Well, this tank gun, it sounds good, by the way, it's mounted on the 1224 tank? Then let the comrades of the first machine factory make an evaluation of this tank gun. Zhang Lao said, looking at the seats on the other side of the first machine factory, and looking at Qin Zhenhua above.

Qin Zhenhua stood up, and then said, "First of all, let's find something. ”

Qin Zhenhua looked around, and then picked up a stick leaning against the corner: "Let's compare this." ”

What is he doing here?

Looking at Qin Zhenhua's appearance, everyone was very curious.

"The armor-piercing projectile is divided into two parts, the warhead in front and the propellant in the back, of course, the warhead of our current armor-piercing projectile is inserted in the propellant, even so, the overall length of the shell is close to about one meter, let's use one meter."

This stick is exactly one meter, Qin Zhenhua held one end, and then, making a very difficult appearance, holding the other end, and then, turning around, and then, his body suddenly shook.

What is this guy doing?

Everyone looked at Qin Zhenhua a little strangely, only the people in the army, but all of a sudden, their hearts were like mirrors, Qin Zhenhua was simulating the scene inside the tank!

Now everyone uses the 59 tank, or drive a distance, stop and put a shot, and then move forward, but even so, it is just a matter of stopping and aiming, and loading the shells is done on the move.

A tanker is definitely a physical job, not only repairing tanks, but also when maintaining tanks, and when loading shells, it is also the same, not only laborious, but also dangerous!

The shells of tank guns are very heavy, and when it comes to the caliber of 120 mm, it is even heavier!

Different shells, the weight is different, the Western, between 20 kg and 28 kg, and the domestic ones, in order to increase the power, the chamber is enlarged, that is, the weight of the projectile is greater.

If you compare it, it's about the same as a bag of flour, not a small bag of flour, or a big bag of flour in the supermarket!

Many people can carry such a large bag of flour, but what if the body is still shaking?

Loading while the tank is moving, the tank is constantly jolting, and at such times, it takes a lot of balancing skills to stuff the shell into the chamber.

What if you miss?

Fifty pounds of shells fell and smashed on the feet of the tankers, which was absolutely a comminuted fracture!

In fact, over the years, in the tank troops, such a thing has happened more than once, and this is just a 100-mm shell, and now, a 120-mm shell, heavy and long!

In a bumpy tank, holding such a big guy, you have to complete the turn, the small space inside the tank, the bumps of the tank, etc., all conditions are against the loader!

Then, Qin Zhenhua stuffed the "cannonball" into the barrel of the cannon, and then made a gesture of closing the cannon door, and continued to turn around.

Why?

Move the second shell!

Tanks, also pay attention to a continuous firing ability, the faster the rate of fire, the better, what to do when a tank faces a group of tanks? Whoever has a faster rate of fire will be able to throw shells faster and pose a huge threat to the other side!

In general, in a minute, several shells are fired!

Qin Zhenhua continued to do this action, again and again, and when he did it for the third time, he bent down and began to hammer his back.

"Qin Zhenhua, what are you doing?" Xie Huimin's face was a little unhappy.

I thought he would support it, but who knows, he came here to make a foreign appearance! We are all good friends, so why should we not be able to get off the stage?

"When I got into a tank, I usually worked as a commander, but that day, I was curious when I watched the hammer waist of the second pillar, so I became a loader." Qin Zhenhua said: "As a result, I am not as good as the second pillar, the second pillar is loaded with five shells, and I am loaded with three, and it is already like this." The loaders of our tank troops should be better, but I think we should have to make some changes, although the tanks are for war, the tankers should not complain, but to prepare a more comfortable environment for the tankers, so that they can maintain their physical strength, in order to better carry out the battle. ”

Looking at everyone, Qin Zhenhua said seriously: "For this tank gun, the test effect of our first machine factory is also very good, with strong armor-piercing ability, great power, and good accuracy, but we are not satisfied with its loading. When we make weapons, we have to take into account the feelings of the users. ”
