"Lao Zhu, what do you think?"

After staying in front of this self-propelled gun for a short time, He Lao asked Zhu Lao, although the original purpose was to see the 80 tank, but in fact, the 80 tank has been seen many times, and the prototype is still in the troops in the capital, so it is not too rare, but the self-propelled anti-tank gun in front of him is unique and eye-catching.

"I think it's the right time for this weapon to appear." Zhu Lao spoke there.

"At the moment, we are replacing the existing 100mm rifled guns with 105mm rifled guns, which should be able to meet the needs for some time, but if the situation changes, we will still be in a hurry."

The main threat at home is the Soviet Union in the north, the Soviet Union is the biggest threat to itself, but it is not the main threat to the Soviet Union, the main target of the Soviets is the Western world, and their rolling torrent of armor is mainly prepared for Europe.

Therefore, those powerful T-64 and T-80 are deployed on the European battlefield, and in the Far East, the largest number is actually T-55 and other tanks.

If the Soviets put the most advanced T-80 to the north of their side, will their existing 105mm tank guns be able to penetrate it? After all, over the years, the T-72 has not been a secret, but the T-64, T-80 these tanks, there has never been any real and reliable news, no one knows what the real bulletproof capabilities of these tanks are.

It's like the conflict that broke out on a certain island in the north at that time, and all the weapons of our side could not penetrate the armor of the T-62 tank! At that time, it was a shock to the whole country.

You don't know how thick the opponent's tank is, what you can do is to increase your armor-piercing ability as much as possible, the higher the better!

"Now, we have set the artillery of the next generation of tanks at a caliber of 125 mm, but the maturity of a gun requires several years of testing and continuous adjustment, and before this tank gun is installed on our tank, our army has a gap of several years." Zhu Lao said: "I think that this weapon in front of me can just make up for this blank period." ”

Qin Zhenhua was moved by listening from the sidelines, and wished that the relationship between the old man and the First Machine Factory was very good, and now he came here and gave this self-propelled anti-tank gun a trust.

Of course, what Zhu Lao said is also the actual situation, and there is not too much exaggeration, this 120 mm caliber self-propelled anti-tank gun, in fact, the real role is to make up for the gap in their own firepower.

According to the current situation, the second-generation tank is a 105 mm tank gun, even if the barrel is lengthened, the increase in firepower is limited, and the 120 mm tank gun is congenitally powerful.

When the army has qualified tanks in the future, and when its own 125-mm artillery has completely matured, the self-propelled anti-tank guns in front of them will naturally lose their meaning.

After all, it is a self-propelled gun, not a tank, its mobility and protection are very poor, and in the modern battlefield, it cannot be attacked, but can only be passively defended on the position, which is not as useful as a tank.

However, as far as the current situation is concerned, the country is to implement the strategic goal of territorial defense, the country is to fight a defensive war, these self-propelled guns, when needed, can be arranged on the preset position, to attack the incoming enemy, this is the meaning of its existence!

After Zhu Lao's introduction, the accompanying officers nodded frequently, and his analysis was quite reasonable.

"How did you solve the problem of its reload?" Someone asked.

At the beginning, the tank on this gun was denied because of the problem of the automatic loader, and now, on this self-propelled gun, how is it solved?

"Well, you can go in and have a look." Qin Zhenhua said: "Let's see how we solve it. ”

The turret is large, the shells are placed in the tail bay, and at the same time this bay can also balance the weight of the gun, and then, you can see that from the tail compartment to the muzzle, there are special mechanisms, which are not particularly complicated.

"This is, a semi-automatic reloading scheme?" Someone has already seen the doorway.

"That's right, semi-automatic reloading." Qin Zhenhua said: "It not only reduces the labor intensity, but also reduces the mechanical difficulty, this is the most concise and effective plan we have come up with, anyway, our self-propelled gun does not need a low shape, only this large turret can accommodate it." ”

"Well, this weapon is cleverly designed." He Lao opened his mouth and said: "Wait until this parade is over, and make a detailed report on this weapon." ”

Hearing this, Qin Zhenhua was overjoyed, which showed that He Lao was already interested in this weapon, and the officers present were also interested!

Now the top priority is the military parade, so this self-propelled anti-tank gun can not be put on the agenda until the end of the parade, and it is time to continue testing and improving it for most of the year.

After chatting about this self-propelled anti-tank gun, the group entered the workshop and began to look at the final 80 tanks on the production line.

"This is a new tank, and we need to do a lot of training, so will the life of the engine be consumed during training?" This concern was asked.

The life of the tank engine is low, which is caused by many reasons, inheriting the characteristics of the Soviets, five big and three coarse, easy to produce, and the processing accuracy is not high, so the life is naturally not good. The engine of the B2 series only has a life of 500 hours, and if it is driven for five hours a day, it will only take 100 days to drive the engine to the end of life.

For other tanks, it is enough to train in a queue for an hour or two a day, but these 80 tanks are new tanks, and the troops must be trained more frequently.

Of course, the military parade is a major event, and if the engine reaches the end of life during training, it will definitely have to be replaced, but after all, this will cost a sum of money, and the troops still have to ask clearly.

"The original engine, the life is 500 hours, the 12150ZL engine produced by the Coal Province Diesel Engine Factory, in addition to increasing the power to 730 horsepower, but also to increase the life to 700 hours, and our further improved engine, in addition to the engine to 800 hours, has also increased the life to 1,000 hours, you can calculate, can it be used on the day of the parade."

Of course!

A thousand hours of life, that's more than enough, and everyone was very happy to hear this answer.

"How did you do that?"

"We researched a plasma spraying process that was applied to the cylinder wall to increase the wear time." Qin Zhenhua said with a smile.

The technology of the Germans is still good, so many 396 diesel engines have been purchased, and the Germans have also exported the technology of the 396 diesel engines.

The engine is most worn out of the cylinder and piston, and the overhaul is actually mainly to replace the piston and cylinder liner, which improves the wear resistance and naturally significantly improves the life.
