If you want to talk about the 152mm tank gun, there are indeed American M551 light tanks. This tank weighs only a dozen tons, but it is equipped with the thickest gun barrel.
Of course, it is not for increasing firepower. Ordinary tank guns use high-bucket pressure guns, just to increase the initial speed of shells. However, this gun has low-bucket pressure, and the speed of shells is not high.
Even so, they can only use armor-breaking missiles as anti-armor ammunition. Its caliber is purely for the ability to launch Xiaoliu anti-tank missiles. Speaking of gunfire missiles, the Americans definitely left earlier than the Soviets.
In the jungle area of Monkey Kingdom, this tank was somewhat adaptable, but it was non-mainstream after all, and it was not particularly widely used.
The mainstream tank guns are currently only 120mm and 125mm caliber. However, for the Soviets, the pre-research of the next generation of tank guns has already begun. In the pursuit of firepower, they are absolutely crazy enough.
It directly transitioned to 152 mm! This is the mainstream caliber of large-caliber howitzers. When firing shells, even if they just hit the tanks, they can destroy the current tanks.
In this era, the caliber is the truth.
Now, this 152mm tank gun is of course different from the 152mm tank gun of the American Sheridan tank. The barrel of this tank is thick and long, and it looks at least 50 times the diameter.
Left and right, so, it will be a smoothbore gun with high pressure.
If you speculate, the power of such a smoothbore cannon will be greatly increased, the internal chamber pressure will be further increased, and the speed of the cannon ejection may be as high as more than 2,000 meters per second. In this way, when the shells fly out
It is estimated that it can penetrate a thick armor of 1,000 mm in size within two thousand meters.
If the T-72 tank is swung over, it is estimated that two can be penetrated with one shot. Qin Zhenhua has no doubt about the power of this tank gun.
However, so far, no tank has carried such cannon barrels. After all, there are gains and losses.
Technology progress has never been achieved overnight, it must have to undergo slow development. So far, 120mm and 125mm tank guns have become the mainstream because all aspects of technology have matured and the engine's power has entered.
With more than one thousand horsepower, related fire control and so on have developed. When it reaches the 152mm level, further development of tank technologies is required.
After all, if you want it to run fast, a two-thousand horsepower engine is almost an essential element. At present, such power is definitely not a matter of saying a word, and there will inevitably be quite a lot of problems.
.
"Yes, tank guns of this caliber are like kings on the battlefield. However, the entire tank design must be surrounded by this tank gun." Qin Zhenhua said.
This design is weird, but it must be a compromise in helplessness. In order to have strong power, it is forced to use two tank engines. How to arrange these two tank engines is a big problem.
Now, we can see that the layout is clever, and Duraba must have thought about it.
The engine was deployed in the middle, and space was left behind. These spaces were arranged in the way of loading.
It does not adopt the existing loading method. All the reserved ammunitions are arranged in parallel in the tailgate, just like multiple rocket launchers. If you want to say that this automatic loading method is very similar to the Western world
The layout plan for the tailings is that the shells are loaded. Anyway, everything is done by automatic loading machines, so there is no one behind it.
32 shells are arranged in four rows, each row is eight, tilted upward, which means that the barrel can only be loaded into the shell at a fixed angle and a fixed position, and will be returned after each shot.
Obviously, it is not conducive to fast shooting.
There is no turret with the current meaning above, but the barrel can be rotated. In theory, the barrel can even be turned to the end to attack the enemy behind. However, considering the loading of shells, this kind of blow will be
It's meaningless. Instead of turning the barrel, it's better to turn the car body over.
"Director Qin, please give some of your views on the design of this tank." Du Laba said to Qin Zhenhua humbly.
He took out this design drawing, not to let Qin Zhenhua and the others praise him, but also hoped that Qin Zhenhua could put forward some opinions.
"The entire tank design scheme looks refreshing, and all the designs revolve around the 152mm tank gun." Qin Zhenhua did not hesitate and immediately began to comment: "However, it is still in operation.
There will be a lot of inconvenience, especially the poor backward shooting ability. Of course, if the Soviet army only attacks in the combat plan, this is not a disadvantage."
Dulaba nodded. Yes, shooting backwards is not easy, but in their combat plan, it is attack, just drive forward is enough!
"The plan is avant-garde and bold, and it is a good plan." Qin Zhenhua continued to praise the other party and said.
"No, no." At this moment, Wang Erzhu suddenly spoke: "I think this plan is still not good enough. Its layout seems to have been compromised, but there are still ways to change, such as
It said that it's crew cabin, I don't think it's good to deploy in the front, I suggest moving it to the back."
Normal tanks always put the tank's hands in front, but Wang Erzhu expressed his point and moved it to the end!
Duraba's eyes lit up: "Speak!"
"You have deliberately pursued front-back symmetry. In fact, I don't think it is necessary. The front is changed to two pairs of load-bearing wheels and four pairs of load-bearing wheels. In this way, the passenger compartment originally designed in the front cabin can be moved to the back
Come on." Wang Erzhu explained: "The biggest advantage of this is that the space in the crew cabin has been greatly improved. You don't have to look for small people from Central Asia anymore. Even tall Europeans can have good driving.
Experience.”
The front of the tank is low and the back is tall. The height difference between the front and rear is at least half a meter! It may even be about one meter! This means that the front passenger compartment, a small man, has to lie down and drive, and the rear passenger compartment,
You can drive normally!
This is definitely a big change, but after such changes, it seems more reasonable.
