Doomsday Bunker Upgrade

When it comes to cannons, many people are familiar with them. This heavy attack weapon, known as the god of war, has a long history. From the moment it was born, it was destined to dominate the main theme of war.

The earliest cannons can even be traced back to the Spring and Autumn Period of the Yan Kingdom more than 2,500 years ago. At that time, a military weapon called "Teng" appeared, which is the ancestor of today's wide variety of artillery.

It's just that the so-called cannons in the early days were to a greater extent fired stone bullets or incendiary bombs made of pine wood and the like. It was not so much a cannon as a huge stone thrower.

However, with the development of history and the invention of gunpowder, the artillery in the true sense had already taken shape in the Song Dynasty. At the latest in the Yuan Dynasty, the artillery in the true sense, the smoothbore cannon, was invented, and the subsequent human history was born. All the cannons ever used.

The appearance of the cannon, a powerful attack weapon, naturally aroused the love of many military strategists in history.

No matter who, as long as he wants to win, he cannot refuse this ultimate plan to win.

With the help of the Urban cannon, the Turks ended the millennium glory of the Roman Empire, and since then there has been no fortress that will not fall.

With the concentrated use of artillery, Napoleon conquered Europe, and since then, artillery has never been absent from every famous battle in human history.

Or even conversely, in every famous battle that has occurred since the large-scale use of artillery, which time has there been no artillery?

It's just that when the barrel of the artillery is made thicker and more powerful, its weight is also becoming heavier and heavier, and the mobility and use of the artillery are naturally restricted.

It is precisely because of this that the Urban artillery has been the largest caliber artillery ever made by humans for quite a long time.

It was not until modern times, with the development of industry and technology, that those super cannons with a caliber that broke through the sky appeared, and the way to transport them was no longer traditionally by human or animal power, but by carrying these big guys on board. the train.

From this, the most powerful artillery ever used in war in human history, the train cannon, was born.

This super cannon that moves on the rails is undoubtedly the largest caliber super weapon ever used by human beings in war. The Paris artillery that Germany used to bombard France in World War I, the Gustav artillery and the Douglas Cannon in World War II Pulling cannons, mass-produced K5 (E) train guns, etc...

Although this kind of super cannon is very troublesome to move or erect, it has to be said that once the super cannon is fired in war, its power is unparalleled.

The Gustav artillery once shot through a 10-meter-thick reinforced concrete fortification, leaving a crater as large as four football fields. In the war, it can be said that nothing can resist its shelling.

But this kind of cannon is still too slow and too troublesome to move, and the caliber of the mass-produced train gun is not large enough.

So is there a cannon that can not only meet the requirements of mobility on the battlefield, but also ensure the caliber of the artillery?

The answer is yes, and someone built it, and the result is what is mentioned in the document Chen Xin received, the ultimate weapon of land warfare built in the Suvian era-Land Cruiser.

To be honest, when I saw this thing for the first time, Chen Xin seriously thought that it was something made up by a science fiction writer, because it was too exaggerated.

After the end of World War II, the Suvians seized a large amount of German technical data, which naturally included the technical data of the train guns that once shined in World War II and the Gustav heavy artillery that had not been completely destroyed.

At that time, Suvia didn't pay much attention to this, and just sent some weapons experts to conduct research and try to imitate their own train guns.

However, with the confrontation between Suvia and the Federation after the war and the escalation of the Cold War, the Suvians felt that they needed a land-based weapon that could withstand the Federation's invasion from the east coast in Siberia, and the train gun naturally became the Soviet Union at that time. One of the key objects considered by the sub-high level.

After all, there is only a Bering Strait between the easternmost end of the territory of Suvia and the westernmost end of the federal territory, and the width of the Bering Strait is only 35 kilometers at its narrowest point.

The Suvians can place super cannons here and directly bombard the homeland of the Federation.

Although this would not make much sense, it was necessary if the Commonwealth were to cross the Bering Strait and attack Suvia by land.

It's just that Siberia is uninhabited, and it is a very troublesome thing to build a railway to deploy train guns.

So when the weapons specialists in Suvia designed a 600mm cannon on two rails, the plan was rejected.

The first is that the mobility is still not enough, because at that time missiles and rockets have been put into use, and the train gun has become less popular and practical.

The second is that Suvia's executives felt that the caliber and power of this thing were still not enough, especially at that time Suvia had already lit up nuclear technology, and the train guns were no longer fragrant.

So the weapons experts in Suvia let themselves go completely and created a second improved version.

They replaced the train wheels of the trailer at the bottom of the artillery with tracks, and made a super-large chassis with sixteen tracks, a super cannon with a caliber of 800mm and a range of more than 70KM, and equipped it with specially designed nuclear shells.

Satisfied at this time, the high-level officials of Suvia ordered a trial production of one, and a test firing was carried out at the weapons testing ground in Siberia.

But this thing has not really come in handy, after all, it is still too heavy.

Even with sixteen tracks, it can barely walk on land, but in Siberia it can only drive normally after freezing on the soil in winter, and the snow will seriously interfere with its progress.

When the temperature is higher and the ice and snow melt, the muddy frozen soil is enough to sink it into the mud.

The most important thing is that this thing is powered by a steam turbine and needs to consume a lot of fuel to move.

So after the test firing, the senior management of Suvia put forward new requirements to the weapons experts, hoping that this thing can be more practical, they can make it smaller, the power is not so great, but it is practical and can be measured. Produce.

The request this time is very reasonable. The weapons experts in Suvia have narrowed their brains a little bit, so a land cruiser that can be put into practical use in a real sense has been built, and two prototype vehicles and a Subsequent improvements.

And this is what is on the document Chen Xin got. One is 74 meters long and weighs 307 tons. It is equipped with a dual-mounted 305mm caliber main gun and uses a small nuclear reactor as a power source. tank".

Well, this thing is my mouth, but it is not impossible to make a train gun into a tank chassis in theory.

Taking the K5 train gun as an example, with a caliber of 280 and a total combat weight of more than 200 tons, it was carried by two railway flatbed cars. At that time, the chassis of two Tiger Kings was used as a support design, and a model was made.

With the technology of the Cold War, it is not impossible to make such a thing.
