Super Weapon Swap System

In later generations, the Chinese chose the 125mm tank gun. When it was finalized successfully, one was very embarrassing.

That is the 120mm tank gun developed by the Han state!

Probably in December of 1978, the development task of 120mm high bore pressure smooth bore gun as a new main battle tank and self-propelled anti tank gun was officially assigned by the five aircraft departments and armored forces. At the end of the year, three high bore pressure ballistic guns came out. The test was successful on February 19, 79.

This progress is quite fast. Just look at the period at that time. It happened to be the period when Hans leopard-2 technology was introduced.

It can be said that the 120 gun at that time was almost a replica of Hans's leopard-2 tank gun.

However, just as the development of 120 mm tank gun and its supporting ammunition was carried out smoothly, the supporting new tank ended without success. The 120mm artillery project, which is about to enter the design and finalization, was interrupted immediately.

Seeing that the gun was coming to an end, the 4447 factory responsible for R & D at that time decided to install the 120mm tank gun on the 321 chassis of the 83 type 152mm self-propelled howitzer in order to keep the upcoming labor achievements, and carried out the factory type test of the 120mm tank gun and armor piercing projectile.

Thus, the 89th type self-propelled anti tank gun was saved. At least the fire was kept.

Tanks are mainly charge and trap. They must have strong armor protection, strong firepower and mobility. However, self-propelled anti tank guns are not needed.

Its only use is to fight the enemy's tanks. Therefore, what it needs is fierce firepower. After the 120 mm gun is installed, it is more than enough to deal with the bear country in the north. It can even penetrate the front main armor of the bear country's T-72 at 2000 meters.

Its combat method is to hide and stand by, find the enemy first and fire first. To be frank, it is to hide secretly, shoot cold shots at the target and kill the target in a short time.

Because there cannot be only one target, sufficient fire speed is a prerequisite for achieving operational objectives.

The design index of this anti tank gun clearly puts forward that the time from the discovery of the target to the completion of shooting shall not exceed 12 seconds, and it can complete the rapid shooting of 3 rounds / 20 seconds and 5 rounds / 30 seconds, and the continuous firing speed shall not be less than 6 to 8 rounds / min.

At the same time, due to the large chamber and fixed loading design, the weight of armor piercing projectile and grenade reaches 23 to 30 kg. In order to solve the contradiction of high firing speed, automatic loading mechanism must be equipped.

However, if the full-automatic loader is adopted, the difficulty will be greatly increased, which will eventually lead to the abortion of the project. Based on the actual situation, 4447 plant has designed a semi-automatic loader with tail compartment structure, fixed-point automatic ammunition supply and manual ammunition taking and loading.

If we can take over this set of structures, we can effectively solve the problems we are facing.

The weight of 120 mm shell is too large, and automatic loading seems to be a good choice, so that all indicators of T-72 can be pressed in all aspects.

However, automatic loading is too difficult. If it is semi-automatic, the difficulty will be greatly reduced, the reliability will be improved, and it is suitable for our own industrial level.

Yes, that's it!

"Mr. Zhu, let's leave this problem to our 4447 factory." Qin Guan said: "we will spend one or two months to develop a semi-automatic filling system suitable for our new tanks. What do you think?"

In addition to automatic and human meat loading, there is another kind called semi-automatic!

Qin Guan can't directly understand the specific principle, but in short, it is to supply ammunition in the tail compartment, automatically deliver the shells, and then slide to the loader. The loader doesn't have to turn around, find the shells, carry the shells, and turn back. As long as the loader pushes his hand, he can stuff the shells into the chamber, greatly reducing the labor intensity of the loader, The risk is reduced and the reliability is high.

Qin Guan said it briefly. Sure enough, there was a spark in Zhu Lao's eyes: "Qin Guan, you are a genius! Well, the fifth Machinery Department will soon issue a formal notice that factory 447 will be responsible for developing this semi-automatic filling device."

We still need the loader, but the loader can save a lot of energy. It's a great idea to adjust measures to local conditions!

It also takes time for the military to test and compare. Maybe Qin Guan can develop it during this time. Zhu always has no doubt about Qin Guan's ability.

After a day at the shooting range, Qin Guan was almost black by the sun, and his skin was extremely dry. At night, there was a dust storm outside.

"How delicious." after returning, Qin Guan smelled a smell: "is this Quanjude roast duck?"

"Yes," said Chen Yutong. "Today, sister Xiang Jing took me to Quanjude. The roast duck there really deserves its reputation. We ate two and brought you back one."

He has been to the capital for many days, but it seems that Qin Guan hasn't visited any scenic spots in the capital, nor has he walked through the streets and alleys of the capital and eaten authentic street snacks.

"Well, it tastes good." without washing his hands, Qin Guan directly picked up a cake skin, put it on the roast duck, add some onions and sauce, and then put it in his mouth and chew it.

The roast duck is oily but not greasy. The taste of the sauce is sweet, and the pungent green onion is mixed into a unique taste in the mouth.

"Well, delicious."

Qin Guan continued to take a piece. At this time, without Qin Guan's hands, Chen Yutong had wrapped it for him and stuffed it into his mouth.

After eating five pieces in a row, Qin Guan finally ate almost. At this time, Chen Yutong continued: "also, sister Xiang Jing said that she may have other tasks and may not continue to follow us."

When saying this, Chen Yutong's black eyes looked at Qin Guan and wanted to see what expression was on Qin Guan's face.

Would it be a pity? Stay? Still happy?

Xiang Jing is a member of the vulture army. She can't always be a bodyguard for Qin Guan. Now she has a task and goes out. It's normal.

Qin Guan heard Chen Yutong's words without any expression. Yes, there was no expression. Chen Yutong didn't give it to him, so he grabbed it with his hand and ate it.

"Hello, brother Qin Guan, I said Sister Xiang Jing was leaving. Don't you have anything to say?" Chen Yutong yelled at Qin Guan.

"Xiang Jing, come out. Is it interesting?" Qin Guan said, "are you two betting?"

Qin Guan's mouth was full of oil and his speech was vague.

Is it fun to lie to yourself? When I came in, I found Xiang Jing hiding in the cabinet. There was a seam in the cabinet. From there, I should be able to see my expression.

Chen Yutong lied to himself that Xiang Jing wanted to leave. Xiang Jing wanted to see his attitude. This was a farce. Therefore, Qin Guan shouted Xiang Jing out without hesitation.

Has Xiang Jing forgotten that she has the ability to find others?

Xiang Jing could only pout and drill out of it. It's hard to imagine that she could put herself in such a small cabinet. It's like practicing bone shrinking skill.

"Well, I admit defeat." Xiang Jing said, "Comrade Qin Guan, I have told you a good news. I have been officially transferred from my original unit to serve as your personal protection task."

With that, Xiang Jing's face became very black: "now, let me teach you a lesson together with Yutong. It's you who transferred me from my original unit!"
