Wang Bin was not surprised by what Wang Xu said, that is, to compare the warship on the surface of the earth Shanghai with the cosmic research and exploration ship Dijiang. After all, for human civilization, the best comparison object is naturally the warship on the sea.


    But for Wang Bin, it''s different. With the technology mall system, he naturally knows the spaceship standard of the first-class civilization in the universe.


    A spaceship with a tonnage of tens of thousands of tons is actually a small and medium-sized spaceship for a first-class civilization, not a large spaceship at all.


    Even for the aerospace civilization that has just entered the first-class standard, the tonnage of the most common small space warships can reach tens of thousands of tons, while the tonnage of medium and large space warships can reach dozens or even millions of tons.


    In addition, when the level of civilization reaches level 1, its civilization also mastered the manufacture of larger space warships, such as super large warships with a length of one or two kilometers and motherships with a length of more than five kilometers.


    In terms of defense and attack power, although the ability of Dijiang class space research and exploration spacecraft is strong, it is still somewhat different from these real space warships, especially those medium and large space warplanes.


    Of course, if human civilization has really produced this spaceship with a tonnage of more than 10000 tons, it will mark that human civilization is no longer a primitive pre nuclear civilization, but a first-class civilization that really has the ability to design and manufacture large space warships. At that time, human civilization will officially enter the ranks of Aerospace civilization.


    After all, the ability to manufacture such a huge warship means that the earth will no longer restrict human civilization, and the whole solar system will become a real paradise for human civilization. Interstellar migration is no longer an illusion for human civilization.


    Therefore, the construction of this spacecraft is very key to the whole human civilization, which is why Wang Bin is very concerned about the manufacturing progress of this spacecraft.


    As time went on, in the expectation of Wang Bin and others, nearly half a year passed in the twinkling of an eye, and the Dijiang class "Dijiang" space research and exploration ship was finally successfully completed and ready for its first flight with the efforts of the whole Tiangong technology and Huaxia official.


    Of course, the completion here does not mean that all the equipment and instruments on the whole spacecraft have been installed. In fact, this is only the completion of the installation of the overall hull and engine of the spacecraft, which preliminarily has the ability of space navigation.


    The next equipment installation will not be carried out at the spacecraft assembly base on the moon.


    Because now the total weight of this spaceship has reached about 12000 tons. If all kinds of equipment are installed on it, the weight of the spaceship will exceed the maximum take-off weight of the spaceship. After all, all kinds of equipment to be installed add up and its weight will reach thousands of tons. If all kinds of weapons and external armor are added up, The weight can reach tens of thousands of tons.


    Moreover, due to the long-term scientific research and exploration mission in the universe, the spacecraft must be equipped with a large number of entertainment facilities and some green plants for the scientific research on board and the physical and mental health of the crew, and these things add up to at least several thousand tons.


    A spaceship of this weight can never take off with the current capacity of human civilization. Even on the moon, the gravity is only one sixth of that of the earth.


    Because of this, other equipment can only be assembled after the spacecraft enters space.


    With the completion of the assembly of the spacecraft, it is finally time to take off. However, because the spacecraft was manufactured on the moon, not many people participated in the spacecraft take-off ceremony. Basically, they are Tiangong technology and official spacecraft builders on the moon.


    In fact, the take-off ceremony of the first spacecraft of human civilization, whether Wang Bin or Qin Lao, is very much wanted to attend. They have even prepared an aerospace plane to go to the moon.


    However, before they got on the plane, Wang Bin was stopped by the order of the superior. Although it has been several years since Tiangong technology developed the aerospace aircraft, the flight sorties of all the aerospace aircraft produced by Tiangong technology have reached hundreds of thousands, and there has been no accident in this process.


    However, despite this, officials still don''t think that Wang Bin and his team are the right choice to go to the moon. After all, no one can guarantee that the aerospace plane Wang Bin and his team will not have an accident. After all, in theory, even the aerospace plane produced by Tiangong technology has a one in 100000 chance of an accident.


    The aerospace aircraft is different from the aircraft in the atmosphere. After doing a good job in safety, even if there is an accident, there is a great chance of survival.


    However, in fact, even if Wang Bin takes an aircraft in the atmosphere, he must make a series of reports before he can take it, and the aircraft he takes must be an aircraft produced by Tiangong technology.


    After all, Tiangong technology and Wang Bin himself are too important for China and human civilization. Once he has an accident, the loss is not only China, but also the whole human civilization. It may even directly lead to the stagnation or even retrogression of human civilization in the field of aerospace.


    It is precisely because of this that the superior directly ordered Wang Bin that they should not go to the moon to participate in the take-off ceremony of the spacecraft at this time.


    Although Wang Bin is very depressed about this, after all, since their Tiangong technology entered the aerospace field, they have developed and produced a large number of aerospace equipment and instruments, including various types of space planes and space stations, but as the boss of Tiangong technology.


    He has never been to space himself, so Wang Bin is also looking forward to when he can go to space in person. Officially, because of this, he wants to go to the moon in person to participate in the take-off ceremony of the first real spacecraft of human civilization.


    But now it seems that Wang Bin''s wishful thinking has obviously failed to start. He can only give up depressed and watch the take-off ceremony on the big screen of the command center.


    Although Wang Bing himself was unable to go to the moon to participate in the take-off ceremony, he still wanted to express his condolences and encouragement to these workers on the moon. Therefore, after the order from his superior, Wang Xuyue, general manager of Tiangong technology, was sent to express his condolences to these workers. After all, whether Wang Bin himself or the official, But it is very clear how much these staff paid for the successful take-off of the spacecraft, and even some people were seriously injured in the process of manufacturing the spacecraft.
