Chapter 591 (1/2)

Wang Bin didn't know about the war in Lao Huang's universe until he got the data. After all, others are not in Lao Huang's world.

Although Wang Bin is also looking forward to the use of space warplanes in Lao Huang's world and the performance data already shown in the war, Wang Bin knows that things like this are not urgent. When the time comes, Lao Huang will naturally give him the data of using these space warplanes.

For Wang Bin, the most important thing now is naturally the construction of the space city. After all, it brings together the strength of the whole China and brings about the construction by tightening his trousers. Naturally, no mistake is allowed. If there is a problem, it will be a huge loss for the whole China.

Fortunately, since the construction of the Pangu space city until now, there has been no mistake in the construction of the space city, and everything is carried out in a tense and orderly manner according to the construction drawings.

Only half a year has passed since the construction of the space city. At this time, all the keels have been basically laid in the central core of the space city. Now the construction of the space city shell and core railgun in this area has begun.

Because the core area of the space city is a railgun barrel with a diameter of 15000 mm and a length of several kilometers, and there are dense superconducting coils on the outer layer of the railgun barrel, it is not easy to assemble. After all, the allowable error between each barrel should reach the nanometer level, so the construction is very slow.

In fact, it is precisely because the requirements of this railgun are very high that the attack power of this railgun is also very powerful.

According to the design data, this railgun can accelerate a shell weighing several tons to about 5% of the speed of light. Relying only on the kinetic energy of the railgun shell, its lethality is very amazing. It can destroy asteroids with a diameter of about tens of kilometers at one time. Of course, if smaller shells are used, Its railgun also accelerates faster. If a shell with a diameter of about 10 cm is fired with maximum energy, it can even accelerate the shell to about 10% of the speed of light. Therefore, this railgun can be said to be the most powerful weapon in the history of human civilization, The maximum energy released absolutely exceeds the energy released by the most powerful nuclear weapons of human civilization.

Of course, the energy consumption of such weapons is also amazing. If human civilization has not broken through nuclear fusion technology, human civilization really can't afford such railguns, and even manufacturing is very difficult.

In addition, in fact, each superconducting coil on the barrel of the railgun is also a superconducting battery, which can also store a large amount of power. Therefore, even if there is no other energy input, the energy stored by the railgun itself is enough for the railgun to launch many times with medium power.

Of course, at full power, it can only be launched once.

Even with the support of nuclear fusion reactors, it takes several hours for the most powerful nuclear reactor in human civilization to launch at full power again. It can be seen how much energy it needs.
