"By the way, do you only have this equipment?" Qin Zhenhua asked tentatively: "It should be more than that?"
Although it has not been officially proposed yet, the news has come out long ago, and everyone is working hard. The second machine factory is also one of the top military industry manufacturers. If you want to say that just such a piece of equipment will not make people no matter what.
Believe it.
Yimai Factory has made great efforts to this military parade. It is estimated that it can be used for seven or eight items, or even ten. As for how many can be selected, of course, I hope that all of them will be selected.
The first machine factory is the boss, and other factories are not to be outdone. There must be other factories’ special products. The second machine factory is the cannon, and the main business is the cannon. Do they have any new equipment to take out to participate in the military parade?
"Of course there is." Xie Huimin said: "What we developed is naturally a big guy."
Big guy? Qin Zhenhua asked curiously: "How big is it?"
"It's bigger than the active ones."
It is bigger than the current service? The largest one in service should be the 152mm howitzer? If it is bigger than this 152mm, what is it?
A super cannon with a caliber of more than 200 mm? Impossible. There is no such project in China. After thinking a little, Qin Zhenhua reacted: "It's just a few millimeters bigger, right?"
It's a few millimeters taller. This is how I played artillery with the British, but now I guess it's still the same.
Sure enough, after Qin Zhenhua said this, Xie Huimin nodded: "That's right, we have almost made a sample cannon, 155mm plus howitzer!"
The military parade just completed last year was a 152mm howitzer, which is also the caliber commonly used in China, while in the West, it is slightly larger, making it a 155mm caliber.
At the same time, there is also a combination of cannons and howitzers.
The main difference between these two cannons is the difference between the body tube and the caliber. The body tube and caliber of howitzer are relatively small, and the body tube is generally 20 to 30 times the caliber. The body tube of the cannon is generally more than 40 times the caliber.
This causes the difference in the combat methods of the two. The howitzer's barrel is short, so it has a small initial speed. In order to launch far, the elevation angle is generally pulled very large, so that the ballistics are more curved, while the cannon
The barrel is long, so that the shells are initially velocity and have a long range, so they can shoot by aiming directly.
The two were originally different, but now, they have been integrated. The howitzer ballistics are bent, which leads to inconvenience in aiming and requires complex artillery accelerator. However, at the same time, because it is a curved shot, it can attack the enemy behind the bunker.
You can also conduct long-distance over-visual strikes on the enemy's rear positions.
The cannon ballistics are straight and can directly aim at a single target to bombard. Therefore, if the tanks are classified, they are actually in the cannon sequence.
The two types of cannons have their own advantages and disadvantages. After the end of World War II, the functions of the two were combined and turned into a killing weapon. This is the Canon howitzer, referred to as the howitzer.
In China, since its founding, the Soviet Union has been introduced, so the Soviet Union's series of howitzers were produced, with calibers mainly 130 mm and 152 mm.
The Soviet Union was artilleryism, so at the beginning, the Soviets' suppressed artillery had the advantage in range and power. However, until the late 1960s, NATO created a 39-fold 155mm howitzer and fired ordinary bombs.
The range reaches 22 kilometers, and the range of launching rocket extended-range grenades reaches 30 kilometers. Not only does it have a long range, but the projectile is also heavy by 5 kilograms.
In this way, the West has begun to have an overwhelming advantage.
By the time the Soviets advanced bravely and developed the second generation of 152mm cannon, namely the 2A36 152mm cannon and the 2A65 152mm howitzer, the West had already begun to have better performance 52/54 times the caliber 155mm diert
gun.
In fact, the diameter is only three millimeters, which is not particularly large. If we talk about the gap in firepower, it is naturally mainly due to the gap in basic technologies such as metallurgy between the two sides. Western technologies such as electroslag recombination steel have long been improved.
With advanced gun steel, it can withstand greater chamber pressure and load more launching medicine. This is the process. At the same time, it is also Western countries in the technical fields of howitzer diameter, body tube, ammunition, sighting, chassis and other technical fields.
Performance advantages achieved after making large investments.
And what about the country?
Of course, the domestic can use existing technology to improve the 152mm howitzer, but in this era, the domestic needs to take its own path.
How should we choose the caliber of the next generation of artillery? In this special period of the 1980s, it was very marketable to move closer to the West.
After all, the overall advantages of the West are still very obvious, and the relationship with the Soviet Union has not yet dissolved. If you want to develop modern artillery in China, of course, you have to learn from the West. Is it necessary to change it back to 152 mm in order to take care of yourself?
On the other hand, of course, it is for export considerations. Now, the domestic economy is developing rapidly, the army is enduring, and military enterprises are racking their brains to sell their products, and in such a big environment
The new generation of caliber chooses 155mm, which means it will be natural. If you sell it, the 155mm caliber cannon will definitely be more marketable.
Even if the target country has 152mm ammunition inventory, as long as the bullet barrel is the same, an ammunition belt can be added and fired from the 155mm gun barrel.
"However, it is not easy to introduce this technology from the West, right?" Qin Zhenhua asked.
The West has let go of itself, but it is definitely not about opening the door. At most, it is just a crack in the door. People's most advanced things are definitely unwilling to take out, and those that can be sent are all backward.
It is not easy for our side to introduce the most advanced 155mm howitzer technology.
Xie Huimin smiled and said, "Yes, it's not easy. This matter is thanks to your push."
Me? Have I ever done such a thing? Qin Zhenhua touched his nose a little strangely. Are the good and bad things ours own?
"Do you still remember that we went abroad for the first time and went to the West to introduce advanced technology and then to Austria?" Xie Huimin asked Qin Zhenhua.
Of course, I know that the technology of electroslag re-fusion steel started to be discussed at that time, and Steyr Automobile also talked about it at that time.
"Actually, after we went there, we did something more confidential." Xie Huimin said: "Now, this matter can be declassified. We met Dr. Boer at that time!"
