When it comes to artillery, many people are familiar with it. This kind of heavy attack weapon, known as the God of war, has a long history and is destined to dominate the theme of war from the moment it was born.

The earliest artillery can even be traced back to the spring and Autumn period of Yan state more than 2500 years ago. At that time, a kind of military weapon called "Yi" appeared, which is the ancestor of today's various artillery.

It's just that the early so-called cannon, to a greater extent, was used to fire stone bombs or incendiary bombs made of pine and other things. It was not so much a cannon as a huge stone thrower.

However, with the development of history and the invention of gunpowder, the true artillery had its rudiment in the Song Dynasty. At the latest in the Yuan Dynasty, the true artillery, the smoothbore gun, was invented, which gave birth to all the cannons used in human history.

In the history of the great artillery, a powerful weapon appeared.

No matter who wants to win, he can't refuse the ultimate plan to win.

With the help of the ulban cannons, the Turks ended the Millennium glory of the Roman Empire, and since then there has been no fortress that will never fall.

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

Even on the other hand, in every famous battle since the large-scale use of artillery, has there been no artillery?

However, as the barrel of the gun becomes thicker and more powerful, its weight becomes heavier and heavier. Naturally, the mobility and use of the gun are also restricted.

Because of this, the Uban cannon was the largest caliber gun ever made by human beings for a long time.

Until modern times, with the development of industry and science and technology, there were super cannons whose caliber broke through the sky, and the way to transport them was no longer the traditional way of relying on human or animal power to transport, but to carry these big guys onto the train.

From this, the most powerful gun used in war in human history, train gun, was born.

This kind of super gun relying on the rail movement is undoubtedly the largest caliber super weapon ever used by human beings in the war. In the first World War, Germany used to bombard France with the Paris cannon, the Gustav cannon and Dora cannon in the Second World War, and the mass-produced K5 (E) train gun, etc

Although this kind of super gun is very troublesome to move or set up, it has to be said that once it is launched in war, its power is incomparable.

Gustav's cannon once shot through a 10 meter thick reinforced concrete fortification, leaving a crater as big as four football fields. It can be said that nothing can resist its shelling in the war.

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

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

The answer is yes, and someone has built it. The result is what Chen Xin mentioned in the document he received, the ultimate weapon of land war built in the suvian era - the land cruiser.

To tell you the truth, when he first saw it, Chen Xin seriously felt that it was made up by some 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, including naturally the train guns that had been brilliant in World War II and the Gustav heavy guns that had not been completely destroyed.

At that time, suvia did not attach much importance to this, but sent some weapon experts to study and try to imitate its own train gun.

However, with the confrontation between the Soviet Union and the Federation and the escalation of the cold war after the war, the suvians felt that they needed a land-based weapon that could withstand the invasion of the Federation from the east coast in Siberia. Naturally, the train gun became one of the key objects considered by the high-level officials of the Soviet Union at that time.

After all, there is only one Bering Strait between the easternmost end of the suvian territory and the westernmost end of the federal territory, and the narrowest part of the Bering Strait is only 35 kilometers.

The suvians could have set up their super cannons here and then bombarded the federal territory directly.

Although it is of little significance to do so, it is necessary if the Federation intends to cross the Bering Strait and attack suvia by land.

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

So when the weapon experts in suvia designed a 600mm caliber cannon with two rails, the plan was rejected.

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

Second, the senior management of suvia felt that the caliber and power of this device were not enough, especially at that time when suvia had already lit up its nuclear technology and train guns were no longer popular.So the weapon experts in suvia completely released themselves and created a second improved model.

They replaced the train wheels of the trailer at the bottom of the gun with tracks, and made a super chassis with 16 tracks, an 800mm caliber super cannon with a range of more than 70km, and equipped it with specially designed nuclear shells.

Satisfied with this, the high-level officials in suvia ordered the trial production of a door, and carried out the test firing at the Siberian weapons testing ground.

But it's not really useful. After all, it's too heavy.

Even with 16 tracks, it can barely walk on land, but in Siberia it can only drive normally after the soil freezes in winter, and 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 make it sink into the mud.

The key point is that this thing is powered by a steam turbine, which needs a lot of fuel to move.

So after the test launch, the senior management of suvia put forward new requirements to the weapon experts, hoping that this thing can be more practical. They can make it smaller and less powerful, but it should be practical and can be mass produced.

This time, the requirements are very reasonable. The weapon experts in suvia have narrowed their brain holes a little, 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 improved one have been completed.

This is what Chen Xin got from the document. It is a "Super Tank" with a length of 74 meters and a weight of 307 tons. It is equipped with a double 305 mm caliber main gun and uses a small nuclear reactor as the power source.
