"Director Qin, you haven't been to our Second Machine Factory for a long time." On this day, Qin Zhenhua appeared in the factory area of Second Machine Factory. Xie Huimin, who came to welcome Qin Zhenhua, said to Qin Zhenhua: "You are fine.
Go to the Three Treasure Hall, what's wrong with this time?"
"What else can I do? Of course, I'm here to see the development of tank guns on your side." Qin Zhenhua said: "I heard that your tank guns have been built, so I'll take a look."
The first machine factory manufactures tanks, but it is more responsible for the assembly. Many parts are purchased from various factories, and tank guns are purchased from the second machine factory.
The second machine factory built guns. In recent years, it has built many tank guns. For example, after introducing the technology of L7 tank guns, it has built a 105mm tank gun, which is still in use, and in China, it is in the
After confirming that the caliber of the next generation of tank guns is 125 mm, the second machine factory began to manufacture 125 mm tank guns. Although the caliber has not changed in recent years, the technology of tank guns has been upgraded.
The chamber pressure is getting higher and higher, and the penetration depth is getting bigger and bigger, becoming the most powerful weapon system for domestic tanks.
With the development to this point, the potential of the 125mm tank gun has been almost fully explored, so according to the plan of the final generation and the pre-research generation, the next generation of tank guns has also been put on the agenda.
"I just knew you came here for this tank gun. Let's go to our shooting range to have a look. After this tank gun was built, it has been sent to the shooting range. We have repeatedly studied the next generation of tanks from various countries.
The plan for the gun was finally decided to start a 140mm tank gun first.” Xie Huimin said.
The trial-making tank gun is different from the formally-formed tank gun. During the trial-making process, you can choose different plans. After repeated comparisons, you will finally determine the most suitable weapon parameters. After the finalization, it will not change again.
It takes a long time, after all, those shells cannot be wasted and must be used.
The caliber of the next generation of tank guns should also be carefully selected.
Although countries are continuing to repair and repair their current tanks to serve longer, the new generation of tank guns is still under development.
Take Europe for example. Of course, the most famous one now is the Rheinmetallr's tank gun used by the Leopard 2 tank. This 120mm tank gun is used in the main battle tanks of many countries. Even the United States directly purchases it.
Past.
As the continuous development, this tank gun is also growing longer. At the beginning, it was 44 times the caliber, but now it has been increased to 55 times the caliber. At this level, there is no possibility of continuing to tap potential. 55
The diameter is already very long. If it is longer, it will definitely be very uncomfortable to use a tank with such a cannon barrel to go to areas such as woods.
Then, if you want to continue to increase the firepower of the tank, you have to increase the caliber.
The Germans planned the caliber of the caliber is 130 mm, which is similar to 120 mm, so it can be easily stuffed into the turret of Leopard 2. The Germans' idea is also very simple, that is, the main body of the tank does not move, only
Upgrade the tank gun so that the weapon upgrade can be completed at the lowest cost.
However, there were not many changes in this caliber and could not satisfy other countries. Therefore, the French decided to increase their main gun caliber to 140 mm. Although their Leclerc tanks have not been in service for a few years,
The next generation of future ground combat systems will use 140mm caliber cannons. This cannon can increase the armor-piercing ability by 70% compared to the existing 120mm tank gun. It can be said that once it is put into use,
It will definitely be a nightmare for the enemy.
Other European countries have basically selected the caliber of 140mm tank guns, which made the French complacent. In terms of tanks, they came from behind and finally could guide the trend of tanks. Moreover, because on Leclerc tanks
, they have already used automatic loaders, so now, they will also install similar loaders for their 140mm tank guns, and there will be no problems.
Looking at Damao, since the collapse of the Soviet Union, Damao has not been nervous. He has been repairing their own T-72 tanks, and finally got a T-90 out. Of course, they also know that this kind of tank is
Those who cannot assume the mission of future ground combat are also developing new tanks. The tank code-named T-14 will use tank guns with larger caliber.
Therefore, the Eastern powers cannot lag behind, and they must pre-research the next generation of tank guns.
Of course, the caliber issue is the first. The current tank gun is already 125mm caliber, so if it is changed to 130mm caliber, the firepower increase is limited and there is no meaning at all. If it is
If the caliber of 150mm is too big, the strong recoil will have a great impact on the tank. Therefore, considering various factors, they first used the caliber of 140mm. Of course, if the test gun is not suitable
, and maybe it will be slightly enlarged to 145 mm.
When Qin Zhenhua came to the artillery test site, he saw such a big guy.
The 140mm caliber is quite thick, and the 50-distance setting makes this tank gun look thicker and longer. Qin Zhenhua actually feels like he looks at the barrel of a self-propelled howitzer.
"The larger the caliber, the more energy the cannon will be out of the muzzle. According to our calculations, the kinetic energy of this 140mm tank gun can reach 22 megajoules." Xie Huimin said to Qin Zhenhua: "Now, our 125
The maximum capacity of a millimeter tank gun is only 11 megajoules. Therefore, our new tank gun can penetrate one meter thick armor from two thousand meters away. All the tanks in service cannot block it.
Hold on to its bombardment.”
The current 125mm cannon can only shoot one meter deep at a distance of one thousand meters. This new tank cannon can achieve stronger destruction capabilities from two thousand meters away. In the world of cannons, it is in the world of cannons.
, The caliber is justice, and the caliber is truth. This sentence is correct.
"Of course, the corresponding recoil is also very large, so it is impossible to draw conclusions whether this cannon should be installed with a tank. However, our experiments are always carried out. If the army needs it, at any time.
They can be replaced, and even our current 99 tank can be tried to replace it." Xie Huimin continued.
