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.


    With the smooth progress of the construction of Pangu City, while focusing on the construction of Pangu City, Wang Bin will naturally not relax in the construction of other key projects of Tiangong technology. For example, Tiangong technology has not relaxed in the production of space warplanes, but since the production of the first space warplane, Up to now, the production of this space fighter has continued. Up to now, their Tiangong technology has produced more than 100 of this space fighter, excluding those taken by Lao Huang.


    At this time, the research and development of a larger production line of this space fighter is also in progress, and the progress is very gratifying. According to the progress, the design drawings of this production line with an annual output of thousands of aircraft have been issued, and have also been reviewed by professional departments. Now their processing plants of Tiangong technology have begun to produce the accessories of this production line, It is expected that this production line will officially enter the production and use stage in a short time.


    At the same time, Tiangong technology has not slowed down the research and development of new models. After all, there is only one model of space warplanes, which is far from enough for human civilization and Chinese civilization. Therefore, human civilization should have more styles and more advanced space warplanes.


    Moreover, with the experience of designing and manufacturing the first space fighter, the space fighter designers of Tiangong technology are familiar with the design of new models. The general has successfully designed the engineering drawings of the second space fighter in less than two months and is ready to start manufacturing.


    Of course, compared with space fighters, in fact, Wang Bin and Qin Lao are most concerned about the progress of the first space warship project of human civilization.


    After all, compared with space warplanes that can only fight in a small range, space warplanes have a much larger operational range, and their protection, attack power and speed are also faster. Most importantly, space warplanes can fight for a long time in the universe, while space warplanes cannot.


    Tiangong science and technology moon base, at this time, a huge spacecraft is under construction. Although it is said that the shape of the spacecraft is not very good, it does not have the sense of science and technology like the spacecraft in science fiction animation or movies.


    Although Tiangong science and technology planned to build the spaceship before, it was ready to directly assemble the spaceship in space, at this time, the largest space station of human civilization, that is, Ziwei space station, has a total tonnage of only one or two thousand tons, such a large space station, It is impossible to build a spaceship with a tonnage of more than 10000 tons or even tens of thousands of tons.


    As for building spaceships like building a space city, it is even more impossible. After all, human civilization has no experience in building spaceships in space. Therefore, Wang Bin and Qin Lao decided to establish an assembly base on the moon and finally transport them to the moon to build spaceships after producing various accessories on the earth.


    It seems that it is not very different from ordinary submarines in the earth''s sea, but there is only one command tower missing.


    At the same time, the position of the submarine''s original propeller has been replaced by a propeller module composed of multiple ion engines.


    At the same time, the original position of the tail rudder has lost its trace at this time, and four high thrust isotope engines have been replaced.
