"This, we are not sure about the first test shot. Let's do this, two thousand meters away, put a 450mm vertical target to give our guests insight." Qin Zhenhua said: "If you can't penetrate it,
, just saw it open and take a look.”
At present, the penetration depth of conventional armor-piercing bombs is about 300 mm, and only the most powerful German Leopard-2 tank can penetrate more than 400 mm. In the war in Israel, they
The M111 armor-piercing popped up well. The Germans introduced corresponding technologies to the past and developed a new generation of armor-piercing bombs. It is said that the depth of the armor-piercing bombs is very powerful, but the specific amount is still a question mark.
Now, opposite Lao Ba is the T-72. Although the armor of this tank is very powerful, it is actually at a level of about 300 mm. After all, the Eastern powers have always targeted Soviet tanks as their combat targets.
Even the 105mm cannon can penetrate it properly. (There is no reaction armor added, and the export monkey version is mixed with quartz sand, which is at this level?)
Even if the opponent strengthens it to 400 mm, it is the limit, so it is enough to put a 450 mm target here now.
"Okay, two thousand meters, four hundred and fifty millimeter targets, hurry up, prepare for it." Xie Huimin said.
As the site of the Second Machine Factory for the shooting test site, there are all kinds of targets here, so they were ready soon. In the attention of everyone, the launching medicine behind them was also stuffed into it.
"Is this kind of gun common to the T-72 tank gun shells?" Berg thought of something and spoke.
"Although the calibers are the same, our medicine room is different from theirs, so the shells are not universal," said Xie Huimin.
There are many different statements about caliber. For example, the two systems of the East and the West have different calibers. For rifles, the Soviets had 5.54 mm caliber, the Americans had 5.56 mm caliber, and the Soviets had 152 mm in terms of cannons.
There are 155 mm Americans. In short, there are always more Americans than Soviets.
Why is this?
So there was an analysis. Of course, for convenience, what should I do if my bullets were used up on the battlefield? I could use it by picking up the Soviets!
The Americans had a slightly larger caliber than the Soviets, so bullets could be used when stuffed in. On the other hand, the Soviets could not use American bullets because they had a small caliber and would explode.
Of course, this is just a random guess from an outsider. In fact, it is definitely not as simple as having a small diameter that can be stuffed into a large diameter. The launching medicine behind it is different, and the shell shell is different, so how to use it?
Needless to say, there is a slight difference in the diameter, even if the diameter is the same, it may not be possible.
Now, the 125mm cannon and shells on our own side cannot be used by the 125mm cannon of the Soviets, because the launching drugs behind them are different!
"The medicine room is different?" Berg looked over strangely.
"That's right, our medicine room is larger, more than 13 liters, which is the largest among all tank guns. In this way, more drugs are fired and the kinetic energy can be obtained by the shells. Of course, this also increases the pressure of the barrel.
There are higher requirements."
Increased ejection drugs can significantly increase the power, but the gun barrel must be able to withstand it.
Hearing this, Berg nodded, and then Qin Zhenhua, who was standing beside him, added: "Tanks, firepower is the king."
That's right, firepower is king!
After the reloading, aiming, and then, from a distance, someone pressed the electric shock button.
"boom!"
A huge roar sounded, and a huge ball of fire suddenly appeared on the other side of the muzzle, and black smoke rose. In front of the fireball, the 460mm tungsten alloy core abandoned the bullet holders on both sides and flew towards the
Come ahead!
"The initial velocity of the muzzle is about 1,700 meters per second." Xie Huimin said: "So, the target two thousand meters away only takes more than one second."
Every data is talking about the strength of this armor-piercing bomb. Now, just as I was speaking, the armor-piercing bomb has hit the target 450 mm thick, and then drilled hard into it.
Under the huge heat, the surrounding metal began to melt, melting, and a molten hole through which the elastic rod was left behind.
Then, the warhead stabbed the target, and the rear wing stuck at the end, and then it stayed in it, the bullet rod that exhausted the last kinetic energy was stuck in the target, like a dart piercing into the mud
generally.
"Pierced?" Everyone was extremely surprised when they heard the report from the target operator. They ran all the way to the target two thousand meters away. Looking at the bullet rod stuck inside, Berg made the decision immediately.
: "This cannon can meet our requirements."
Although the T-72 tank on the opposite side also carried a 125mm cannon barrel, it actually couldn't even reach 300mm deep. According to Qin Zhenhua, it was about 220mm, which was really bad enough.
, while the same 125mm tank gun of the Eastern power has penetrated more than 400mm!
The 450 mm target is just between passing through and passing through. In fact, it can be considered as penetrating. How can this performance not be satisfactory?
"Once we have completed this project, we hope that this supporting shell can be produced in our country." Berg then made another request.
A big country must be able to produce weapons by itself. They not only have to produce tanks, but also shells!
"That's the case." Qin Zhenhua sorted out his words and said: "The production of this kind of shell requires advanced technology. The processing of the support can only be completed by CNC machine tools. The smelting of the rod is even more complicated, so
, You should try to produce tanks first. When your technology improves in the future, we can consider exporting the production technology of this shell. However, recently, you really can't do it."
Berg laughed: "That's right, it's not possible now, but in the future, we can definitely produce it ourselves!"
Needless to say, Lao Ba, even the San opposite him does not have the ability to produce shells. Their shells are purchased, so there are often conflicts and fires a few days of cannons and then buy shells from abroad.
.
Lao Ba is stubborn about giving birth to himself, but they are not as obedient as Ah San, so they are still very clear about what they can do.
After seeing this tank gun, Lao Ba was able to return home satisfactorily after seeing the delegation. After sending Lao Ba away, Qin Zhenhua was left by Xie Huimin and others and discussed another important matter.
