According to the design data, after one revision after another, the final confirmed tonnage of this spacecraft stayed at 12,000 tons.

After all, the place where the spacecraft is assembled is on the moon. Although the moon’s gravity is only one-sixth of that of the earth, it still has gravity. Therefore, after the construction of the spacecraft is completed, it must be separated from the moon’s gravity.

With the current technology of human civilization, it is already the largest capability to send a spaceship of more than 10,000 tons from the moon into space. If the tonnage of the spaceship continues to increase, then with the current technology of human civilization, It is impossible to send it into space at all, even if the moon does not have the resistance of the atmosphere, the gravitational force is only one sixth of that of the earth.

What's more, with China's current technology, although it is capable of building ships of 100,000 tons or even larger, in terms of building submarines, it has not yet built a submarine of more than 10,000 tons. On top of the submarine, of course, even if the construction of more than 10,000 tons is already very risky for Huaxia, let alone a bigger one.

In addition, there is another situation, that is, what Wang Bin and the others wanted to build was a purely military spaceship. After all, for the current human civilization, the most important thing is the military spaceship. After all, the threat of alien civilization is at hand.

But considering that the current technology is not mature enough, and compared with the military-type spacecraft, there is actually another kind of spacecraft, which is more important to human civilization, that is, the scientific research space measurement spacecraft.

Therefore, after discussions with high-level officials including Wang Bin and Mr. Qin, it was finally decided that military-type spaceships can be slowed down first, and a scientific research-type space exploration and space survey ship should be built first.

After all, in the next few years, Warm Civilization will build a large-scale base on Mars, but now human civilization's understanding of Mars is very limited, and it can even be said that there is no chance.

Therefore, before human civilization builds a Mars base, it is necessary to conduct large-scale exploration and understanding of Mars before construction can be carried out.

And if we don’t use large-scale cosmic scientific research, exploration and measurement ships, but use ordinary small spacecraft to detect Mars, then according to the situation, after human civilization wants to build Mars, it will take at least 20 or 30 years.

After all, the equipment and instruments that can be carried on a small spacecraft are very limited, basically only one or two types can be carried, and the functions of the equipment are also very limited due to the limitation of the size of the aircraft.

The large spacecraft is different, not only can carry a large number of equipment, but also large equipment,

It can even carry a large number of scientific workers on the spacecraft for a long time to conduct research on Mars on the spot.

In addition, since human civilization wants to build defense facilities in the asteroid belt, it is natural to have a certain understanding of some basic data of the asteroid belt, such as the magnetic field, celestial bodies, and ambient temperature.

And all of these require large-scale space research ships to be competent.

It is also for these reasons that in the end Wang Bin and his Tiangong Science and Technology related departments and the relevant official departments, after discussions, confirmed that the space research, exploration and measurement ship should be built first.

"Mr. Wang! Our scientific research ship was named the Dijiang class after consultation with multiple parties, and the first ship was naturally named the Dijiang according to the convention.

The Dijiang-class research ship is designed and manufactured by Wenming Tiangong Technology. It is the first generation of spaceships in our human civilization that can truly be used for deep space navigation. The ship is 195 meters long, 11 meters wide and 9 meters high. .

According to the previously proposed design requirements, this spacecraft can not only carry nearly a thousand people's daily necessities for more than two years, but also carry a large amount of the top scientific research equipment of human civilization.

Of course, at present, no possible equipment has been installed on this spacecraft, including any large-scale scientific research equipment.

After all, according to the design, the empty weight of this spacecraft has reached 12,000 tons. Such a weight is already the maximum weight for this spacecraft to take off from the moon and enter space. If various equipment is added, then With the maximum take-off weight of this spacecraft, it is impossible to let it take off.

Therefore, all scientific research equipment must wait until the spacecraft is completed and enters space before it can be outfitted. In this case, no matter how heavy the weight of these equipment is, it will not affect the take-off of the spacecraft on the moon.

In addition, since this spacecraft is specially developed for exploring the universe, this spacecraft has very powerful space exploration capabilities.

But this can only be in the solar system. Due to technical reasons, this spaceship does not have the ability to achieve super-light speed and sub-light speed, and even when sailing at full speed, it cannot reach one thousandth of the speed of light.

In addition, the size of this spaceship is still too small compared to traveling outside the solar system, and the materials it carries are also very limited. It is impossible to escape the solar system at all.

Of course, as a spacecraft that has to engage in dangerous tasks such as exploration in the universe for a long time, it will definitely encounter various dangers, such as asteroid belt impacts, etc., so this spacecraft not only has strong armor. It also has a strong attack power, not even worse than the firepower of the professional military escort spaceship we designed in the early stage.

First of all, the thickness of the armor of the hull itself, even the weakest part, has reached 500 mm, and there are installation points for external armor on the outside of the hull. If necessary, thicker external armor can be installed armor.

In terms of attack, this spaceship is not only equipped with four large bow missile launching units, and more than a hundred small missile launching units, but also equipped with various types of artillery, rail guns, and laser cannons, as well as a large number of Its ammunition, with its firepower, is enough to destroy an asteroid several times larger than this spaceship.

It can be said that the safety of this spacecraft in the solar system is completely guaranteed by the military. In the video, Professor Dai, the person in charge of the spaceship, introduced to Wang Bin.

Although Wang Bin already knew the data of the spaceship very well about Professor Dai's introduction, but Wang Xu who was beside Wang Bin didn't. stay.

You know, this is a scientific research ship! It's not a combat-type space battleship for fighting alien civilizations, but it's just a scientific research ship that has such a powerful firepower configuration, which makes him a little suspicious of life.

"Mr. Wang! This is a scientific research ship? You won't lie to me! With such a force configuration, even the most powerful warship on earth may not be able to defeat it!" Wang Xu said after recovering.
