Type 72-k 25mm anti-aircraft gun. Just by looking at the caliber, you will know that this is definitely a rapid-fire braided barrage anti-aircraft gun.
It was developed in 1939 and put into production in 1940. Its iconic features are the long main gun barrel and
The excellent ballistic performance it brings has a good effect against any low-altitude raiding enemy aircraft.
After all, the aircraft these days are all fixed-wing electric fans, and jets have not yet spread to the battlefield. Low-altitude and low-speed targets are the targets that small-caliber rapid-fire anti-aircraft cannons are best at dealing with.
The 72Ks actually delivered to the Red Army were given the mission of regimental-level low-altitude defense. In most cases, they were equipped to the infantry regiments of the Red Army as towed anti-aircraft guns. A small number of them were loaded into the back of GAZ trucks and equipped with
A vehicle-mounted anti-aircraft gun group is a simple self-propelled anti-aircraft gun, which is quite similar to the Middle East green uncle pickup truck that traveled across the yellow sands in the 21st century.
Now, this anti-aircraft gun with excellent ballistic performance and simple and reliable structural design has been selected by Kogin as the main weapon of the new concept infantry fighting vehicle and mounted on the newly designed turret to prepare for testing.
Being able to choose such a small-caliber anti-aircraft gun, which seems to be a new approach now, as the main weapon is not like the traditional medium and heavy armored vehicles, which directly mount a single large-caliber artillery on a small car, horse-drawn
The role Shenke played in it and the opinions he put forward to Kejing can be said to be indispensable.
At the beginning of the design, according to Kogin's idea, a low-pressure artillery with low magnification but large caliber may be the most suitable for this kind of infantry fighting vehicle. After all, according to the design expectation, the mission of the infantry fighting vehicle is to transport
It also provides fire cover for the infantry on board the vehicle and provides fire suppression during the attack.
Since the enemy is suppressed with firepower, it is natural that large-caliber artillery is more effective.
Furthermore, there is no need to place too much emphasis on the range anyway. You don’t need to care too much about the curvature of the battle within visual range. Therefore, the relatively compact low-magnification large-caliber low-pressure main gun is simply the most suitable choice. Kojin’s subordinates
Those designers also think that this design direction is reliable. For suppressing the enemy, what weapon is more exciting and effective than a large-caliber artillery?
When Kogin relayed this design idea to Malashenko and said that he planned to equip the new infantry fighting vehicle with a 76mm low-pressure and low-magnification main gun, Comrade Ma immediately felt the smell when he heard this.
, so damn familiar!
The first-generation infantry fighting vehicle is equipped with a large-caliber main gun with "double low" characteristics. What is it doing here? Is it the BMP1, the ancestor of the BMP family? The entire weapon system is short of a baby anti-tank missile. Kojing can advance this
Over the years, the weapon system design of bmp1 has been restored to the "youth version". Isn't this too fateful to a certain extent?
Leaving aside the current dual low-characteristics main guns, they are still not up to the level of the BMP1 that can fire tail-stabilized armor-piercing projectiles. Even if it is against a hard target with armor protection, it will not be unable to fight back. Some people now think
The foreseeable bad flaws were enough to give people a headache, and Malashenko felt it was necessary to let Comrade Kotin know how bad this design idea was.
"No, no, no, this matter is not that simple, Comrade Kogin."
"You have to consider several issues. First of all, the design we made is to accommodate people, and it has to accommodate an entire infantry squad. Moreover, our body and chassis are not a new design. They are modified from the chassis of a medium tank.
, even the power system has not changed, just the layout has been changed."
"The front part is a longitudinally arranged power compartment, the middle part also contains the turret fighting room and the gunner and the commander who is a part-time loader, and the rear part is a special infantry cabin. This layout is already quite cramped and very crowded. Especially for a medium tank originally
The designed power system already takes up a lot of space, but the reality is that we cannot redesign it and can only use it universally."
"Think about it carefully, Comrade Kejin. Based on what I said above, let's think about the problem of large-caliber artillery shells and ammunition racks that take up a lot of space. To give a simple example, do you think there are too many people stuffed into a T3476?
After moving to a squad of infantry, other things including the original vehicle crew and internal structure remain unchanged. Is there still room for artillery shells? Even if you forcefully stuff them in, how many can be stuffed in? What about the continuity of firepower on the battlefield?
?Once the firepower is continuously interrupted, big problems will occur."
"..."
Malashenko raised a very simple and straightforward question: bomb load.
Yes, the space inside the chassis of the T43 is almost the same as that of the T3476. Strictly speaking, it is even smaller. After all, the height of the vehicle is deliberately lowered in order to reduce the front projection area and the chance of being shot.
In this way, it means that you have to put an entire infantry squad into a chassis that has a smaller internal volume than the T3476, and the things that are already there remain intact and unchanged.
Calculate how much ammunition it can hold - 76mm main gun ammunition and coaxial machine gun ammunition.
Ke Jing, who was very close to me, really didn't consider this issue. He was suddenly asked by Comrade Ma on the spot and was a little confused.
He wanted to refute it, but Kogin thought carefully about what Malashenko just said. Hey! It seems to make sense. This is the situation.
As far as Malashenko is concerned, Comrade Ma clearly knows that the various makeshift designs of the T43 are no better than professional infantry fighting vehicles like the BMP1. At most, this thing is easy to produce during the war years. In order to be able to
Although it was finalized and put into production and the output was quickly increased, it compromised on the design. The actual battlefield role was limited to a makeshift gadget that "sometimes has better performance than crushing it with human flesh."
BMP1 has a custom-designed body with a reasonable layout, but your T43 does not have a modified version.
The bmp1 has a specially customized and designed power system that is small in size but has plenty of power, and your t43 modified version does not have that either.
The length, width, height, height and internal structure layout of the BMP1's body and chassis are all optimal configurations based on the premise of a professional infantry fighting vehicle. You still don't have a T43 with a modified version, and the whole body is full of "make do" atmosphere.
In short, it is simply unrealistic to have this large-caliber main gun on an emergency infantry combat vehicle modified from the T43. In addition, Malashenko has not talked about high-rate fire suppression, suppression fire accuracy, and effective suppression distance.
There are many other problems, which are difficult to achieve under the current fire control equipment and technical conditions. It is simply not feasible for the previous "double low" artillery to be used as the main gun.
It may look ideal and awesome on paper, but Malashenko can completely guess how bloody this thing will be on the battlefield and how big of a problem it will expose.
It is no exaggeration to say that it is trivial to make people cry without tears, but to make people die without a burial place is the basic daily routine.
