Super Weapon Swap System

If you want to frighten the other party, you must take out the real big killer. In the past, Qin Guan had been fooling Dr. bull and asked Dr. bull to beat the 203 mm naval gun first.

As expected, Dr. bull is difficult to cooperate with others, because Dr. bull's character is too arrogant, which will offend many people. At the beginning, the project in maple leaf country was good, but it was cut down. One of the big reasons is that he can't deal with the world. Otherwise, it would be enough to loosen his hand a little with so much scientific research funds in Eagle country.

Before Qin Guan had time to instruct everyone to pay attention to the cooperation with Dr. bull, now everyone was cold. This guy was spitting fire all over his mouth. He said the people here like dog shit. It was about to break up in one shot. Fortunately, Qin Guan finally came on the stage.

When I saw Qin Guan, other people's eyes also showed expectant eyes. It would be good if President Qin came. Look at President Qin. Dr. bull can't communicate and cooperate with people at all. He is completely stubborn. As long as he put forward it, it is absolutely correct and everyone can only obey.

Truth, that's refuted. This guy looks like he's on top. It's disgusting.

Everyone was looking forward to it. Now, Qin Guan had not taken good care of everyone's emotions, but first talked about Dr. bull. When Dr. bull heard that he was going to develop this super cannon, he was immediately excited.

"In this case, the caliber should be at least 300 mm. If it can be 400 mm, it is definitely the best," Dr. bull said. "You are finally going to launch the super cannon project!"

Super cannon, does it cost much?

In fact, it's not much. The main investment is to build this gun, which needs advanced alloy materials. Now the Han country has electroslag remelting steel, which is enough. After it is built, this kind of gun will reach its service life by firing hundreds of rounds. The service life of large caliber guns is not high, but this does not mean that it will be abandoned, the rifling will be flattened, and the chamber can be expanded, Continue to use and expand the chamber twice. The side wall of the gun is not thick enough. It can also launch smooth bore shells. In short, the service life can be guaranteed.

For example, Dr. bull's initial research was to connect the 406mm naval guns used by the two Eagle Navy battleships, expand the caliber, and finally make a giant gun with a length of 36 meters and a caliber of 424 mm.

It is the most common way to bore a naval gun.

Such large caliber artillery shells are destined to be specially developed, and Dr. Bull has long had a set of advanced experience.

In the past, the most famous super cannon was famous for directly hitting the capital of Jiguo. At that time, the range was only more than 100 kilometers. However, now, with the development of technology, the chamber pressure is improving and the performance of propellant is improving. Therefore, it is no problem to hit 400 kilometers with the same caliber.

Various accessories, loading mechanism, etc. Dr. Bull has long had a series of methods to solve them. Now the development of technology also makes it easier to aim. We can specially develop a gun aiming computer for it.

Dr. bull was eager to try. Just then someone spoke.

"Mr. Qin, if we talk about large caliber artillery, we also have ready-made things." the speaker's hair is gray and wears glasses like the bottom of a thick wine bottle. He pushed his glasses. It seems that it took a lot of effort to say these. After all, it's a past project and it's no longer a leak.

"We have?" Qin Guan was also very strange.

"Yes, yes. In the past, we had a pioneer cannon, project code 640-2. This project has a 420 mm cannon."

420 mm? Upon hearing the old man's words, Dr. bull immediately looked excited: "God, that's good news. I like you."

Dr. bull is like a fickle child. He was just scolding everyone as shit. Now he has smiled at the old man.

420 mm, this is a good caliber!

Why didn't you know that the state of Han was also engaged in this kind of cannon?

A group of people got on the plane and went straight to the site of the 640 project. On the plane, only Qin Guan was qualified to listen to the old man tell the story of the 640 project.

At that time, both bear and eagle had three times the speed of sound of reconnaissance aircraft. At the same time, bear had an anti missile system, while Han had nothing. Therefore, Han was also thinking of launching its own project. The pioneer cannon was developed at that time.

Its main use is to launch nuclear warheads into low earth orbit to intercept near earth aircraft and intercontinental missiles entering the airspace of China!

Han's air defense missile technology was backward and it was impossible to break through. Therefore, at that time, there was no other way but to start with anti-aircraft guns.

The key research and development unit of this project is 2210 Institute. They first carried out tests on 85 mm smooth bore guns. This was the largest caliber anti-aircraft gun at that time.

After modification, the initial velocity of a 4 kg projectile reached 1200 m / s. however, this is only the initial experiment, which is obviously unrealistic to hit into space.

Then, the rebuilt special anti-aircraft gun appeared. This kind of smooth bore gun with a caliber of 140 mm fired an 18 kg warhead with an initial speed of 1600 M / s, a firing height of 74 km and a range of 130 km.

If you want to intercept spacecraft and intercontinental missiles in low earth orbit, you still can't, but this is already a considerable achievement.

In this achievement, they continued to make persistent efforts, increased the caliber to 320 mm, developed special sub caliber rocket afterburner and solid ram afterburner, and finally determined their own plan after experiments on this kind of cannon.

This is the 420 mm pioneer super cannon!

After all, only with artillery of this caliber can shells have enough space to equip nuclear warheads, and only nuclear warheads can have enough destruction ability.

Like the anti missile systems deployed by the bear state near the capital in this era, they all use nuclear bombs to deal with nuclear bombs. Detonating each other's nuclear bombs in space is much better than exploding in their own cities. Even if they will suffer some harm, it is worth it.

After all, it will take decades for accurate impact. By 2020, the NMD system will not be completely mature.

This old man was the project leader at that time. It was a crazy era. The West knew Dr. bull's super cannon, but did not know that the Han country actually had the same cannon.
