At the beginning, when Qin Zhenhua was in charge of caliber selection, as a technician of a tank factory, what he had to consider was of course not the question of which gun had more firepower, but a comprehensive consideration.

Therefore, considering the end, it can be found that the problem of loading is the biggest problem! Moreover, he will not make a decision on how to choose, he is just here, laying out all the problems and solutions, so many experts and so many army commanders present, he can always come up with an opinion.

The plan for loading the tail compartment of the turret, in fact, Qin Zhenhua does not like it, the large turret has not changed, and the whole body will go up, which does not meet the needs of the domestic army with a low hull, and at the same time, the tail compartment can only put more than 20 shells, and the rest of the shells are still loaded in other places, so once the tail compartment is finished, it is necessary to manually move other places to the turret tail warehouse, of course, more than 20 shells in a battle, it is estimated that there are a lot.

Now, he introduced the loading scheme of the T-72 tank, which seems to be more complicated, but it does not need to increase the volume of the turret, and it can also ensure a low hull, which has obvious advantages. "The ammunition is deployed in this circle as a whole, and if it is hit here, will it bring about the destruction of the tank?" Just then, an officer asked.

This circle is right at the seat of the turret, and the position of this seat should be the weakest point.

"That's right, if it is hit here, the consequences are terrible, and there is a chance that this turret will fly." Qin Zhenhua said: "We can only increase the protection here, and at the same time, rely on more advanced fire extinguishing and explosion suppression systems to extinguish possible explosions." However, even the so-called tail warehouse method in the West is not a sure thing. Therefore, tank crews are very respectable. ”

When a tankman looks majestic, in fact, once the tank is hit, nine out of ten tankers will be killed, but so what? When you fight, can you be afraid of sacrifice?

Back then, there was a song about tank crews, which had such lyrics that if we were hit, then, our tanks, would give us a metal grave.

When you are a tank soldier, you have already made such an awareness, if you want to ensure your absolute safety, it is impossible, the best thing is to fight bravely, and blow up the enemy's tank first, won't you be able to ensure your own safety?

(The death of the T-72 in the Gulf War made the Soviet tank very discredited, and even had to be renamed the T-90 tank later, because the name of the T-72 has become stinky, but this is not entirely to blame for its turntable automatic loader, but more about the fire extinguishing and explosion suppression device that basically does not work properly and the pot with poor defense capabilities as a monkey version.) Later, for example, in the Syrian war, the turret of the T90 tank did not fly, and the blown miraculous Leopard 2A4 flew the turret, which can tell the story. ）

"I think that of the two automatic loader schemes, this turntable method is more suitable for us." After asking the question, the officer nodded in satisfaction, and then expressed his opinion.

As the caliber increases, the loader's physical strength is limited, and the automatic loader is a necessity, and in both ways, everyone almost unanimously prefers the latter.

Tankmen don't like turrets, which means a greater probability of being hit, and tank designers don't like turrets, which means more complex designs and more body weight.

At this time, Xie Huimin's mind was thinking rapidly, the duel between these two schemes, it seems, is a 125mm tank gun, more suitable?

No, absolutely not, they have been developing it for so long, will this 120-mm tank gun disappear from now on?

Since the sixties, they have been working on the 120-mm tank gun, and until now, they have put too much energy into this tank gun, and they definitely can't bear to watch this tank gun fail.

"Split ammunition is also problematic." Xie Huimin spoke: "Our full-mounted shells can be inserted into the projectile cartridge, which can reduce the overall length, and at the same time has greater potential, which is not comparable to the split-loading shells!" With our later development, the boom of armor-piercing shells will become longer and longer, so the potential of split shells in the future is limited. ”

Now, the tail stabilized shelling armor-piercing projectile is already the most common main armor-piercing projectile, and its important indicator is the length-to-diameter ratio, the larger this value, the stronger the armor-piercing ability!

In the overall way of loading, the rod can be stuffed into the cartridge, but the separate loading is not good, so he feels that this defect cannot be overcome by the other party!

"Now, the tank guns of the Soviets, regardless of the larger diameter of the muzzle, but the armor-piercing ability is not as good as our 120-mm tank guns, which is an example." Xie Huimin said.

Don't look at the thick barrel of the Soviets, however, the armor-piercing ability is not as good as the Western 120-mm tank gun, which has been obtained in practical tests, the tank is used to fight, the tank gun is used to penetrate the enemy's tank, naturally the greater the potential, the better.

That's the point!

Don't talk about an automatic loader! The problem of automatic reloading will always be solved, but the problem of theoretical power cannot be avoided.

"yes, that's a problem." Qin Zhenhua said: "Therefore, we need 125 mm tank guns even more, we have advanced artillery-making technology, we can develop advanced 125 mm barrels that can withstand chamber pressure far more than the Soviets' tank guns, we can also increase the medicine room, continue to increase the power of tank guns, so that down, the performance will definitely have a great improvement." Director Xie, what do you say? ”

What we use is not the original tank gun of the Soviets, don't look at it is a 125 mm tank gun, both domestic and Soviet, it is absolutely impossible to use it universally, and the domestic tank gun, the medicine room must be the largest in the world! Nothing else, it's always okay to plug the propellant to increase the power of the tank gun, right?

The caliber is 5 mm larger, and the propellant, of course, can be stuffed a lot more!

As for the problem of the boom of the armor-piercing projectile, it cannot be stuffed into the cartridge, and other ways can be thought of to solve it, to say that the power of the 125-mm tank gun is insufficient, it is a one-sided idea.

Xie Huimin was speechless, not knowing what to say, and after a long time, he raised his head: "So, you support the plan of the 125 mm tank gun?" ”

"I just said all kinds of advantages and disadvantages, if you want to make artillery, our second machine factory is an expert, how to choose, or everyone has the final say." Qin Zhenhua said: "However, there is one purpose that will not change, tanks, firepower is king!" ”
