Due to the success of the research of the warp engine, the Ming Empire has also begun to enter a new era, the warp era, and when manufacturing the warp engine, the Ming Empire has also made a major breakthrough in materials, so now the Ming Empire can already make a more huge spaceship with the existing technology, and if the materials for the new breakthrough of the Ming Empire are used to make spaceships, then the Ming Empire can make the size of the spaceship into a spaceship of more than 100 kilometers.

This is a huge breakthrough for the Ming Empire, because whether it is in the mall or in the galaxy, there are very few civilizations that can build such a huge spaceship, and such a spaceship is already a real heavy space warship.

Because such a spaceship has reached the mothership level of spaceship, so after the breakthrough of new materials, the Ming Empire immediately launched a new shipbuilding program, but because the spaceship that needs to be manufactured this time is too large, there is no way to manufacture it in the earth orbit and the lunar orbit, because such a spaceship can already have an impact on the earth and the moon due to its own gravity.

Therefore, Zhu Lei has to consider reconsidering the construction of a shipbuilding base, and it is already very reluctant to make fifteen-kilometer warships in these shipyards near the earth, so there is no need to think about it near the earth.

And there are many addresses for Zhu Lei's new shipyard in the solar system, but considering the development of the Ming Empire in the future, there are actually not many places for him to choose, among which Zhu Lei values four places the most, the first is the original asteroid belt between Mars and Jupiter, but now this place is very empty, and even meteorite fragments can not be seen.

All asteroids and meteorites have become the raw materials of Mars and the materials of spacecraft, so the empty asteroid belt has become one of Zhu Lei's choices for building a new shipbuilding base, but this place also has its own shortcomings, that is, with the development of the Ming Empire, it is getting faster and faster. The entire solar system is getting busier and busier, and in the future, this place will definitely be the gathering of many factories in the solar system, and so Zhu Lei still chose to give up here, after all, it is enough to only make large and super-large spaceships here, but if you want to make a mothership-level spaceship, this place is still not good enough.

The second is in the Kuiper Belt, but the asteroids in the Kuiper Belt are too threatening, and the distance from the earth is too far, which is very inconvenient, and because it is far away from the sun, the energy consumption in the Kuiper Belt is also very large, and there is no energy provided by the sun, all energy consumption depends on nuclear fusion, which is too expensive for a shipbuilding base, not to mention that there are no factories here except for an airport, all the factories are in the inner circle of the solar system, There is not even a factory for refining minerals, so the construction of a spaceship manufacturing center in the Kuiper Belt was also vetoed by Zhu Lei.

So there are only the last two options left, but the difference between these two options is actually not very big for Zhu Lei, and Zhu Lei has thought about these two places in the future, and he will definitely build a shipyard in the future, but it is just a matter of size.

The first of them is in the orbit of Jupiter, because of the huge size of Jupiter, it is very feasible to build a shipyard in Jupiter's orbit, and Jupiter also has a strong magnetic field, which can effectively resist the damage caused by the solar wind to transform various instruments in the shipyard, and because Jupiter's volume is very large, Zhu Lei even if he makes the largest spaceship in Jupiter's orbit, the impact on Jupiter is minimal.

And since there is no living life on Jupiter at all, even if the spacecraft is made to have a slight impact on Jupiter, it does not affect the big picture.

However, there are still certain limitations to making spaceships in Jupiter's orbit, and the nature of making spaceships in Earth's orbit is almost the same, when the size of the spaceship exceeds a certain level, the gravitational influence between the spaceship and Jupiter will be very serious, but that will be a matter for the future, and that will wait until humans can build fortress-level spaceships.

Therefore, the second location is because the orbit of Jupiter and the orbit of Saturn are at a long distance, so the shipbuilding base of the fortress level will be selected here in the future, these two places are the most important to Zhu Lei at present, but for the fortress-level spaceship, the Ming Empire can't make it at all now.

So this matter is not in a hurry, so Zhu Lei's main thing now is to build a shipbuilding base in the orbit of Jupiter that can make a mothership.

With Zhu Lei's order, the entire Yongan Group began to get busy again, and the spaceship design department of Yongan Group not only had to design new spaceships, that is, mothership-level spaceships, but also to design shipyards that could manufacture mothership-level, so it can be said that the entire Yongan Group began to be busy from top to bottom.

You must know that Zhu Lei's Yongan Group is not the Yongan Group of decades ago, and the current Ming Empire is not the Ming Empire of decades ago.

However, even with the current efficiency of Yongan Group, it will take twenty or thirty years to build such a shipyard, so the difficulty of borrowing this shipyard can be imagined.

The new shipbuilding base has a diameter of more than 1,000 kilometers, and it is also in the form of a honeycomb like the old shipbuilding base, but the spaceships that can be built in this shipbuilding base are not only incomparable in size and efficiency compared to the old ones, but also cannot be compared with the spaceships that can be built at the same time.

The largest spacecraft can be built at the new shipbuilding base at 1,500 kilometers, and there will always be five such spaceships at the same time at this new shipbuilding base.

The technology of the 1500-kilometer spaceship is not yet available in the Ming Empire, even if it is the latest material in the Ming Empire, it can't be done, after all, the 1500-kilometer spaceship is already a large space carrier, and such technology people don't have it at all, but for the future development of the Ming Empire, the shipyard must be owned, and after the technology is available, it can be manufactured immediately, or when the Ming Empire has the ability to manufacture such a spaceship, it is trying to make a shipbuilding platform. Then a lot of time will be wasted, which is completely unnecessary.

With the passage of time, mankind's first spaceship with low-speed navigation finally drove out of the shipyard of the lunar shipbuilding base, which is no less significant to the entire human race than the launch of the first satellite of mankind, and also marks the Ming Empire has become a higher civilization in the galaxy, of course, in Zhu Lei's mall system, the Ming Empire is only a middle-level civilization.
