Chapter 1598: Pioneer Cannon

If you want to frighten the opponent, you must come up with a real big killer. In the past, Qin Guan had been fooling Dr. Bull and asked Dr. Bull to smash the 203 mm naval gun.
As expected, it is difficult for Dr. Bull to cooperate with others because Dr. Bull’s personality is too arrogant. Such a personality will offend many people. The project in Maple Leaf Country was good at first, but it was cut off. One big reason is that he is too innocent to live in the world. Otherwise, the Eagle Country's so much scientific research funding will be enough to let go.
Before Qin Guan had time to tell everyone, pay attention to cooperating with Dr. Bull. Now, everyone is cold. This guy, his mouth is full of fire, and the people here are like shit, and he needs a shot. The two broke up, but fortunately Qin Guan finally played.
When I saw Qin Guan, the eyes of other people also showed expectation. It would be good if Qin came here, but take a look at Qin. This Dr. Buhl can't communicate with people at all. Cooperating with people, he is completely stubborn, as long as he proposes it, it is absolutely correct, and everyone can only obey.
Truth, that was refuted. This guy's appearance is disgusting.
Everyone was looking forward to it, and now, Qin Guan hadn't taken care of everyone's emotions, but first moved Dr. Bull. When Dr. Bull heard about the development of this super cannon, he was immediately excited.
"In this case, the caliber must be at least 300 mm, if it can be put to 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 is not much. The main investment is to build this gun. Advanced alloy materials are needed. Han Guo now has electroslag remelting steel, which is completely enough. A few hundred rounds will reach the end of life. Large-caliber artillery has a low life span, but this does not mean that it will be scrapped. The rifling is flattened. You can continue to expand the bore, continue to use, and expand the bore twice. The side walls are not thick enough to fire smoothbore shells. In short, the life span can be guaranteed.
For example, Dr. Bull’s initial research was to connect two 406 mm naval guns used by Eagle Nation naval battleships and expand the caliber to finally make a 36-meter long gun with a caliber of 424 mm.
Expanding the naval gun is the most common way.
This kind of large-caliber artillery shells are destined to be specially developed, and Dr. Bull has already had a set of advanced experience.
In the old days, the most famous super cannon was famous for directly hitting the capital of the chicken country. At that time, the range was only more than 100 kilometers. But now, with the development of technology, the chamber pressure is increasing and the performance of the propellant It is improving, so it is no problem to hit 400 kilometers for the same caliber.
Various attachments, loading mechanisms, etc., Dr. Burr has already had a series of solutions to solve, and now the development of technology has made it easier to aim, and it can be specially developed for its aiming computer.
Dr. Bull was eager to try, and at this moment someone spoke up.
"Mr Qin, if we talk about large-caliber artillery, we also have something ready-made." The speaker has grayed hair, wearing glasses like the bottom of a thick wine bottle, he pushed his glasses, like It took a lot of effort to tell these things. After all, it was a past project, and it was no longer a leak.
"We have it?" Qin Guan was also very strange.
"Yes, yes, we used to have a pioneer cannon, project code-named 640-2 project, this project has a 420mm cannon."
420 mm? Hearing what the old man said, Dr. Bull suddenly looked excited: "God, it's really good news, I like you."
Dr. Bull is like a fickle kid who was still scolding everyone as shit, and now he smiled at the old man.
420 mm, this is a good caliber!
Han Guo is actually doing this kind of cannon, why didn't he know?
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 this old man telling the story of the 640 project.
In that era, both the bear country and the eagle country already had reconnaissance planes at three times the speed of sound. At the same time, the bear country had an anti-missile system, while the Han country had nothing. Therefore, the Han country was also there. I started my own project, the Pioneer Cannon, which was developed in that era.
Its main purpose is to launch nuclear warheads into low-Earth orbit to intercept low-earth vehicles and intercontinental missiles entering Han's airspace!
Han's air defense missile technology is backward, and it is impossible to break through. Therefore, at that time, how bold the people are and how productive the land is, there is no other way but to start with the anti-aircraft artillery.
The key development unit for this project is the 2210 Institute. They first tested on the 85mm smoothbore gun. This was the largest caliber anti-aircraft gun at the time.
After modification, the muzzle velocity of the 4 kg projectile reached 1200 m/s. However, this is only the initial experiment, and it is obviously unrealistic to hit the space.
Then, a rebuilt special antiaircraft artillery appeared. The smoothbore with a caliber of 140 mm fired an 18 kg warhead with a muzzle velocity of 1,600 m/s, a shot height of 74 kilometers, and a range of 130 kilometers.
If you want to intercept spacecraft and intercontinental missiles in low-Earth orbit, it is still impossible, but this is already a considerable achievement.
In this achievement, they continued to make persistent efforts, increased the caliber to 320 mm, and came up with special sub-caliber rocket afterburner and solid stamping afterburner. After experimenting on this cannon, they finally determined their plan.
This is the "Pioneer" super cannon with a caliber of 420 mm!
After all, only a cannon of this caliber has enough space for a shell to equip a nuclear warhead, and only a nuclear warhead can have sufficient destruction capabilities.
Like the anti-missile system deployed by the bear country in this era near the capital, nuclear bombs are used to deal with nuclear bombs. It is better to detonate the other party’s nuclear bomb in space than to explode in your own city, even if it suffers. To some harm, it is also worthwhile.
After all, if you want a precise impact, it will take a few more decades. By 2020, the NMD system will not be fully mature.
This old man was the project leader at the time. It was a crazy age. The West knew about Dr. Bull’s super cannon, but they didn’t know Han, who actually owned the same cannon.
