Zhang's topic led to the question of the caliber of tank guns. After hearing his words, Xie Huimin said: "Yes, so we also made 120mm tank guns, which were used in the 1224 and 1226 on the 1st machine factory.
Although the tank is similar to the previous 122 tank prototype, it is actually completely different.”
The three-hydraulic sample car in the past was a 122 tank sample car. It was still in the 1960s and built a 120mm tank gun. However, it was only the technology from the 1960s. In fact, it was used to build a 100mm rifled gun.
That equipment and technology, so how can the performance be compared with the current 120mm tank gun?
Now the 1224-like prototype is equipped with a newly developed 120mm tank gun, which uses electric slag remelting steel, which is completely the current quality standards. It is created in this way, and the performance has been completely transformed.
!
When talking about this, Xie Huimin's expression on his face was quite proud: "We believe that this tank gun can fully serve as a standard tank gun for future tank troops."
The caliber of the 120mm tank gun is now the caliber of the three generations of the main battle tanks in the West. Except for the British holding the technology of rifled guns, other countries use smoothbore guns. Germany first built the 120mm
Smoothbore guns, France and other countries followed closely. As for the United States, although the current M1 tank is equipped with 105mm guns, it has been discussing with Rheinmetall to directly purchase their 120mm tank gun technology.
The domestic caliber is also 120 mm, but this has nothing to do with the West, and it is not for political choices, such as facilitating the supply of shells in the war years, etc.
In fact, it is not possible to be used for ammunition with the same caliber. In addition to the caliber, the pharmacy is also a very important indicator. Domestic tank guns are completely self-developed, and the pharmacy chambers of the pharmacy chambers and Western tank guns are simply
Different, so it cannot achieve common purpose.
When we first got the 115mm smoothbore gun of the T-62 tank, we first reduced the caliber and built a 100mm smoothbore gun for experiments. Then, we also expanded the caliber to 120mm. The figure shows that the firepower is greater than the 115mm caliber firepower
Be more ferocious.
The tank gun that is equipped with three-hydraulic tanks has long been out of date. Now, after introducing advanced Western technology, the 120mm smoothbore gun rebuilt is completely new, with higher chamber pressure and lighter barrel.
, first-class quality!
Xie Huimin was quite satisfied with this tank gun, and the effect of the experiment on the 1224 tank was also quite good.
Although whether it is a 1224 tank or a 1226 tank, it is mainly for the experiment of tank chassis, since the artillery has been installed, of course, it has also undergone many test firings.
"Okay, in the afternoon, you can report on the specific situation of this tank gun." Old Zhang said.
Suddenly, Xie Huimin was overjoyed. Mr. Zhang asked him to report, which naturally means that there is hope for this tank gun? Is there still great hope?
His heart was already shocked by great joy. Although Zhang Laolai and his second machine factory were here to observe on the surface, in fact, Mr. Zhang's real purpose was to make their tank gun! I'll come here in the afternoon.
Special report, and then, maybe with Mr. Zhang, their tank guns can officially become standard tank guns for domestic third-generation tanks!
Now, of course he knew that the Tank Design Institute was surveying and mapping the T-72 tank, and at the same time, it was also investigating the 125mm tank gun. The future competition for tank guns must be this one, and China can only choose among them.
One is for equipment!
This is very important. It is related to the development direction of the tank soldiers in the next few decades. It can be said that it is of great significance. Therefore, several meetings were held internally, but they did not unify them. Now, Mr. Zhang is here, so he will definitely unify them.
!
Thinking of this, he felt even more excited. Looking at Qin Zhenhua over there, I wonder which solution he would support?
In short, Xie Huimin still has great confidence in his heart.
After the founding of the People's Republic of China, all the equipment in China was from the Soviet Union. Take artillery for example. Our largest caliber is 152 mm, the West is 155 mm, and our rifles also use the Soviet caliber. It can be said that
, moving closer to the Soviet Union was the most common thing in the past.
But now, the country's gates have been opened, and various domestic equipment have begun to move closer to the West. Take howitzers for example, they are already making 155mm howitzers. Of course, this tank gun is also moving closer to the West, with a caliber of 120mm.
The most suitable one.
With this idea, he was also in a state of mind during lunch. Finally, the afternoon meeting was held in the conference room of the Second Machine Factory.
"Our 120mm tank gun weighs 2.6 tons, and the barrel is 6 meters long, which is 50 times the caliber. We know that if we want to make the energy of the tank gun fully use the power of the launching medicine, we must increase the gun as much as possible.
Although we use this length to increase the difficulty of processing, it ensures the power of the shell."
At this time, the Western benchmark is Rheinmetallurgical Company's 120mm tank gun. This kind of tank gun is only 44 times the caliber, while its own side has increased to 50 times the caliber, just to ensure that the tank gun has sufficient power.
.
You should know that the longer the barrel, the more work the fired medicine will do. When the shells fly out, there will be a big fireball at the muzzle, which is also energy, but it has been wasted.
"In terms of specific performance, we launch our current tail wing stable shell-out armor-piercing missile, with a warhead weighing 7.33 kg, a length of 655 mm, an initial muzzle velocity of 1800 meters per second, and a homogeneity of 500 mm can be penetrated at a distance of 1500 meters.
If you change to another method, the effective penetration distance of the 150 mm/68-degree homogeneous deck exceeds three thousand meters, the direct shooting distance is greater than two thousand five hundred meters, and the kilometer target density deviation is not greater than 0.26 meters.
X0.26 meters. Moreover, this is just a first-stage shell. In the future, as we continue to develop new shells, the armor-piercing depth of this tank gun should exceed 700 mm, or even deeper."
When he talked about these data, many tank experts present sighed softly, and the officers of the tank unit stood up in surprise.
What, five hundred millimeters?
what does that mean?
Now that the 105mm tank gun was introduced in China, everyone was relieved. The emergence of this kind of tank gun finally made them no longer rely on their flesh and blood when facing the Soviet tanks.
Regardless of sacrifice, you will go around the side of the enemy to kill the enemy, and you can penetrate the opponent's main armor from the front of the enemy!
And this is just a penetration depth of more than 300 mm.
Now, the power of the 120mm armor-piercing bomb must be increased by one point. Since tanks such as 1224 are mainly for chassis test drives, and artillery testing is not the most important project, so everyone didn't pay attention to it. Now, it is the first one.
The official report, the 500mm depth of wear really scared everyone.
The statement behind is even more powerful, that is, they can operate this cannon and fire at the enemy's tanks at a distance of 2,500 meters!
