Tank, firepower is king, this is a basic principle, in the armies of the great powers of the East, has always advocated firepower first.

So, how exactly do you achieve firepower first?

Larger-caliber artillery is needed, of course! The larger the caliber, the more propellant it can launch!

So far, the 120 mm tank gun has shown the performance of the sky, Xie Huimin and others believe that the performance of this tank gun is enough for the tank troops to meet, but they did not think of the other problems caused by this, restricting the performance of this tank gun.

Qin Zhenhua was asked to analyze and investigate, Qin Zhenhua did a lot of work, and now, these reports have come out.

The shells are too heavy and need an automatic loader, and if you want to build a mature and reliable automatic loader, it is more appropriate to imitate the Soviet way, and if you imitate a qualified automatic loader, then you need to divide the ammunition!

120 mm tank guns, naturally, can also be used for sub-loading ammunition, but since they are all sub-loaded, why not choose a larger scheme?

Now, Xie Huimin has understood, and there is suddenly an endless sense of loss in his heart.

Is their 120mm gun going to fail like this? They have been studying this tank gun for so many years, and they are full of confidence, and now, are they going to start all over again?

Sure enough, after the voting began, one of the experts and one of the officers present all expressed their approval of the design of the 125-mm tank gun, and there was no room for turning back.

"Our 120 mm tank gun, the chamber is already 12.5 liters, if we do a 125 mm tank gun, the chamber can be further enlarged, I propose to increase it to 13.6 liters, how?" Zhu Lao said on the side.

Many people like to find their ancestors for domestic equipment, such as tank engines, which are related to German tank engines, and the same is true for tank guns, domestic 120 mm tank guns, in fact, have nothing to do with foreign ones, and from the launch room, you can also see a lot of clues.

The domestic 120 mm tank gun has a firing chamber of 12.5 liters, while the foreign one, such as the 120 mm tank gun of the Germans, has a firing chamber of 10.5 liters, and this gap is also very large.

At that time, the Germans also kept this tank gun secret, and it was impossible for them to obtain any information, and their tank gun was actually inherited from the past.

The domestic 125 mm tank gun, and the Soviets' 2A46 tank gun, also has nothing to do with the Soviets' tank gun, the Soviets' tank gun, the chamber pressure is not high, under normal circumstances is only 450 megapascals, and their own 120 mm tank gun, the chamber pressure is already 560 megapascals, as for the 125 mm tank gun, the chamber pressure is higher.

These data are all normal chamber pressure at 15 degrees Celsius, and the tank gun also has a maximum chamber pressure data, for example, the maximum chamber pressure of the Leopard-2 tank gun is 710 megapascals, this data sounds very unheavenly, but this maximum chamber pressure means that it can withstand such a launch, and wait until the next launch, whether to explode or not, then it is fate.

In terms of tank gun technology, with the proficiency of electroslag remelting steel and self-tightening of body barrels, the performance has surpassed the Soviets' tank guns, and this 125 mm tank gun has no relationship with the Soviets' tank guns, and it is its own self-developed equipment.

The caliber of the future tank gun was set at 125 mm, which was the result of comprehensive weighing, and after analyzing the problem of automatic loading and the problem of firepower, it was finally fixed on such data, and these key data, Zhu Lao had the right to speak.

Before the development of the tank, Zhu Lao was originally a cannon maker, and Zhu Lao's empty sleeve tube was caused by an accident during the test gun.

"That's right, our country's future tanks will be caliber 125 mm, which is the best plan to get from all factors, and we will build our tank guns according to this plan!" Zhang Lao said: "This task is still handed over to our second machine factory to undertake!" ”

The design and manufacture of a tank gun needs to go through many considerations, and it is not simply to expand the current 120 mm tank gun to 125 mm, and now, this decision is issued, which is equivalent to the need to overturn and restart, the caliber is determined, the chamber is pressed, and the medicine room is determined, and it will take several years to complete the manufacture of this tank gun.

At this time, Xie Huimin only felt a huge sense of loss in his heart, could it be that the 120mm tank gun was about to disappear because of this?

I'm really unwilling!

However, this tank gun was a failure after all, damn the reloading problem! It has nothing to do with tank guns, it has to do with loading, how can you use this reason to exclude 120 mm tank guns? That's a bullshit reason!

Not only Xie Huimin, everyone in the Second Machine Factory has a sense of loss, today Zhang Lao came over, they were very happy, especially when it came to the 120mm tank gun, they originally thought that they could be decided, who knows, they were actually denied!

What a dramatic ending.

"At the same time, since we have decided to adopt a 125-millimeter caliber tank gun, then, I suggest, perhaps we can simultaneously map and map the artillery missiles that imitate the Soviets." Zhang Lao said: "After all, this is a kind of equipment developed and matured by the Soviets, and it would be a pity if we didn't use it." ”

Although the medicine room is different, as long as the caliber is the same, it is a smoothbore gun anyway, and this kind of artillery missile can be used!

Missiles are generally propelled by their own engines, while artillery-launched missiles are an alternative type, which is to put missiles in the barrel and launch missiles with propellants.

However, due to the great technical difficulty, many countries gave up halfway, and the Americans only developed a matching missile on the Sheridan tank, with a super large caliber, and took an alternative route, and the rest was only developed by the Soviets.

The Soviets also have a hard time, after all, the Soviets' tank guns are not far enough, and they always suffer losses in the battle, and they can only work artillery missiles, and they have already gained something, the artillery missile codenamed 9M112 has now been equipped with their T-64 and T-80 tanks in the equipment sequence, which can be regarded as completing a gorgeous counterattack, long-distance strike? I'm better than you!
