For a cannon, the larger the caliber and the longer the range, there is nothing to say. At the same time, the larger the caliber, the larger the warhead, and the greater the power of the shell. The 155mm cannon can kill a basketball
If you are on the field, the 203mm cannon can kill a football field.
However, at the same time, the larger the caliber of the artillery, the larger the weight and the less convenient it is to operate. Therefore, large-caliber guns can only be loaded on warships. After all, only warships have enough tonnage and space.
During World War II, the largest caliber naval gun had exceeded 400 mm. Iowa's 406 mm and Yamato's 460 mm naval gun were both top-notch at that time.
However, on land, the 155mm cannon has been the main force for a long time. After all, it is already very bulky at this caliber. The 203mm howitzer is even more bulky. Therefore, only the United States and the Soviet Union have such howitzers.
The existence of the Eastern Power has never been studied.
This is the first time!
Under the leadership of Xie Huimin, Qin Zhenhua came to the workshop beside him, and the super cannon appeared in front of him.
"I have to thank Dr. Boer," said Xie Huimin. "Dr. Boer not only brought us the technology of 155mm howitzer, but also brought us the 203mm howitzer plan. We carried out the plan according to the plan he provided.
After several years of research and development, the first 203mm howitzer was finally made."
45 times the diameter, in theory, the diameter is not very large, but the diameter is so large, multiplied by 203, you will get the terrible data of the gun barrel that is more than nine meters long.
Such cannons are definitely super cannons.
Because the gun body is too heavy, the tires under it also have two rows of front and rear! The tires are relatively flat, so when traction, they can also have better road performance.
At this time, the gun barrel was flat and stared at the front, and the gun mount behind was more than three meters long. This was a last resort to balance the impact force of the cannon when firing. This kind of cannon must be operated.
It's quite cumbersome.
"This kind of large-caliber cannon uses separate shells." Xie Huimin said on the side: "In order to increase the rate of fire, we have used a special ammunition transmission device next to it."
Xie Huimin said while giving Qin Zhenhua advice. This ammunition transfer device can ensure that the cannon using the ammunition can load ammunition from any angle and reach a maximum rate of fire of 3 rounds per minute, and a continuous rate of fire of 1.5 rounds per minute.
abilities. For such a super cannon, this rate of fire is already quite good.
At the same time, on the other hand, it is also because its shell is too heavy. Not to mention the launching medicine, just talking about the warhead, the bottom concave bullet weighs 95.6 kg, the maximum range is 40 kilometers, the bottom displacement bullet weighs 100.1 kg, and the maximum range is 5.
Ten thousand meters.
If we look at the range, it is no longer very different from our own 155mm gun. However, its warhead weight is several times that of the 155mm gun. Once this shell is fired, it will definitely suppress the enemy's artillery fire from a long range.
That's true.
To put it simply, after encountering enemy artillery fire, our side will immediately suppress the artillery fire. If it is a 155mm gun, it will only kill one gun position with one shot. However, this 203mm gun will definitely kill it with one shot.
The opponent's entire artillery position!
Those who are close to you will be blown away directly, and those who are far away will be shot to death, and there will be no survivor. The power of such a large-caliber cannon is so terrifying!
Qin Zhenhua nodded: "Yes, it's a good thing to have this bullet loss device, but I don't think it's enough. It's best to make this kind of gun into a self-propelled one."
155mm can be a tow artillery. At Qin Zhenhua's suggestion, a special auxiliary power device has been added, so you can temporarily move your nest. This 203mm cannon is too huge. If you want to operate an artillery squad, it is really
Quite complex.
Therefore, only by designing it as a self-propelled one can it be convenient for the operation of the army.
Hearing Qin Zhenhua's words, Xie Huimin frowned: "It's probably not easy to make this thing into a self-propelled one. We don't have this technical reserve, so why don't we work together?"
Just like the Type 83 self-propelled howitzer used to be, it was just a collaboration between everyone. Later, the second machine factory was used to cooperating with the first machine factory, and even dependent on the first machine factory. It is easy to enjoy the cool under the big tree, and the first machine factory is
Anything can be done.
"We don't have technical reserves, either." Qin Zhenhua said: "But Americans have it. If we find a way to get an American M110, that's great."
It is different from its existing self-propelled howitzer. Because the cannon is too large, this self-propelled howitzer is destined to be naked without a turret. Moreover, it is estimated that when it is launched, in order to resist recoil, relying solely on the track chassis is not enough.
There must be a hydraulic hoe. This thing has been developed too slowly by yourself, so it is better to find a mature product to learn from.
If you want to learn from it, of course it is the American M110.
This is the same 203mm self-propelled howitzer, which uses a tracked chassis and five pairs of load-bearing wheels. Because this self-propelled howitzer is older, its performance is not very good, and its maximum range is less than 30 kilometers, which is completely inferior to that of the company.
This 203mm howitzer from our side has powerful performance.
Get an American?
Xie Huimin looked at Qin Zhenhua with excitement, knowing that as long as he thinks, he can do whatever he can. If he can get it and change it to a self-propelled chassis, it would naturally be even better.
"Of course, after we got it, we just borrowed it. After all, we don't produce their chassis. We borrowed technology and could improve it on our 80 chassis or even the 59 chassis.
It is in line with our actual situation." Qin Zhenhua opened his mind and started talking too much.
It is impossible to produce a chassis specifically because of this howitzer. The chassis of that medium-sized armored vehicle has been promoted and widely used, but it is not cost-effective to produce one for it alone.
"In addition to the track chassis, we can also find the navy and whether their ships have the need to carry large-caliber artillery like ours, which can be converted into naval guns."
The navy's naval guns must have better moisture-proof treatment, etc., but the main body is still common. Qin Zhenhua is racking his brains to find more use occasions for this gun.
"This year's International Defense Exhibition can also bring this gun to the international market."
