――――――

Li Lan's arrival made the originally peaceful valley lively.

Outside the mountain on the right, after two small doors opened, more than a dozen scientists in white coats walked out of the mountain, and because they were inside the mountain every day, everyone's face showed a pale face that had not seen the sun for a long time.

The most striking thing was not the scientists with messy hair, but the mountain behind them, a huge gate at least eighty meters high and hundreds of meters wide, and beneath this tight gate, a huge track stretched from the gate into that strange device in the middle of the valley.

Such a huge iron gate, placed on a steep cliff, is not much smaller inside. And there are also large iron gates like this on the other two sides of the valley on the steep cliffs. Three gates, facing the huge device in the middle of the valley. It's easy to think of something!

"Welcome Commander!" More than a dozen scientists got into a small car similar to an electric tourist car, came to Li Lan and the others, and as soon as they got out of the car, they all greeted Li Lan excitedly.

"Fortunately, after work, you have time to come out and bask in the sun. Also tidy up your own attire. Looking at these pale and sloppy scientists, Li Lan couldn't help but say.

"Thank you for the Commander's teachings, but I wonder where the Commander wants to visit first?"

"Let's take a look inside." Li Lan pointed to the mountain with the gate closed and said.

Surrounded by more than a dozen scientists, Li Lan got into the car. Head towards the mountain on the right.

Li Lan had only come to this place once since it was built, and now it was only the second time he had come here. The car was parked in front of the small door. Everyone got out of the car and walked through the small door.

As soon as you enter the small door, you will feel a burst of coolness and comfort, but anyone who comes here for the first time will not care about this. Because they were already deeply shocked by what they saw. The gate I just saw outside was surprising enough, but when I came inside, the surprise was insignificant.

There is no such thing as a cave. It's a word that doesn't encapsulate what it feels like to see. Because it is like another world inside, the space is very huge, and the whole mountain has been hollowed out. It was full of all kinds of large equipment, busy figures everywhere, and various passages criss-crossed.

Li Lan, who had already been here once, did not show too much surprise, and Tanya, who came here for the first time. It's a little distracted. Especially in the middle of the mountain. On a long giant orbit, an assembled launch vehicle has been placed at this moment, and the crew, who is at the head of the launch vehicle, is assembling the satellite into it.

"This is assembly plant No. 1, which can assemble two launch vehicles at the same time. And this No. 1 assembly plant and No. 2 and No. 3 assembly plants connecting the other two mountains. After the scientists led Li Lan and the others in, they began to introduce, one of the aerospace scientists. Pointing to the launch vehicle that had been assembled, he introduced: "This is our Red Alert No. 1 launch vehicle." Now it has been assembled, with three-stage solid-fuel propulsion, capable of sending satellites with a total mass of more than five tons into geosynchronous orbit, and the carrying capacity of low-orbit is 100 tons. With the help of the gravitational acceleration of the Earth at the equator, the carrying capacity can be increased by 25%. It's just a pity that these launch vehicles can only be used once, and when they are separated, they will explode and destroy themselves. ”

"How many launch vehicles have been assembled so far?" Li Lan asked.

"Three launch vehicles have already been assembled, and the retrofitting of satellites is underway."

Li Lan nodded, he was quite satisfied with this progress. In fact, the structure here was all completed by the base, and Li Lan just clicked the icon to confirm the construction. When the time came, the mountains had become empty, and the equipment inside appeared.

Except for that layer of cement on the valley outside, everything here was created by the base. Li Lan, who came here for the first time, was also shocked. It's not that Li Lan didn't have such a jishu to complete such a project, but time. If it is built and excavated by hand, it will take at least one or two years to complete such a project after meeting all the manpower needs and jishu support. And under the creation of the base, it is only a short period of time. It's a god-like speed.

The same is true for these launch vehicles, which are all produced at the base and are produced here. However, the base is not responsible for assembling it for you, but requires engineers and scientists to be in charge. The same is true for satellites, which are produced by the base, which need to be lifted off by a launch vehicle, and also assembled into the launch vehicle themselves.

In order to prepare for the launch, Li Lan has successively produced 12 spy satellites, and at this moment, these 12 spy satellites have been assembled in three assembly plants. Once assembled, the satellite is ready for launch.

As for the device in the middle of the valley, it is a horizontally lying satellite launcher, and the assembled haode satellite will be transported to the device through the orbit, and then slowly lifted and erected by the device, and after the preparation work of Zuihou is completed, the launch device will be slowly lowered, and the ignition device will be connected. As for the pool below, it is a heat dissipation effect, the flame is sprayed into the pool, and the water absorbs the heat and vaporizes, thus avoiding melting other objects. Of course, something like a launch mount must have been made of materials that are resistant to high temperatures. Moreover, there are deflector grooves on both sides of the launch frame, and the white smoke that comes out six seconds before the rocket is launched is actually water vapor! Even so, the launcher will be a little deformed after launch, and it will have to be repaired again after each launch! And immediately after the launch, firefighters sprayed water to cool down.

And this peculiar-looking launcher is also a product of the base. At least for the time being, Li Lan has not been able to produce titanium steel with such a high-strength structure, nor can he come up with a high-temperature resistant paint to coat it. Moreover, this launch frame mode, even if all the scientists in the integration base are integrated, cannot be manufactured.

There are a lot of subtleties involved, and it is not a very simple matter to lift such a huge launch vehicle. Not to mention, a device that looks so simple is enough. The advantage of this is reflected in the simple two words. A launch pad, a lift-up device, just these two things, the rest is nothing.

The development of space is one of the areas that Li Lan is most concerned about, and in his view, its significance is no less than that of the modernization of the navy, army, and air force. In today's Shijie, more attention is paid to the four branches of the military, and some countries have included the air and space in the direction of the development of the new service. It may not be obvious now, but in the future, aerospace technology, whether in the civilian or military fields, will only become more and more important.

The spy satellite given to him by the base, to be honest, Li Lan was very satisfied. How many generations of people dream of the sky, if it is starting from scratch, then Li Lan himself does not know when he will be able to catch up with the footsteps of Shijie countries. Without the support of the air and space, the modernization of the navy, the army, and the air force will be incomplete. Regardless of the considerations, the expansion of the aerospace domain is extremely important, and at the same time, the development of the aerospace domain is also the most powerful symbol of a great power.

Spy Satellites:

Efficient space reconnaissance and exploration experimental unit, construction price - 500,000 base funds, construction time 168 hours.

Note: When building, you can choose the type of satellite, space "messenger" communication satellite, space "remote sensor" earth resources satellite, space "weather station" meteorological satellite, space "guide" navigation satellite, space "spy" reconnaissance satellite, space "broadcaster" broadcast satellite, space "mapper" geodesic satellite. It can be mainly divided into two major capabilities, active and passive, with complete functions, and there are four major categories: photographic reconnaissance satellites, electronic reconnaissance satellites, missile early warning satellites, and marine surveillance satellites. There are various types of orbits, from low orbit to geosynchronous high orbit.

When the commander reaches the ultimate authority, perhaps, there may be a satellite with the ability to attack! There may also be a space station!

Special note: Its resolution can reach the leading level of Shijie with an accuracy of 0.05 meters, and it can detect targets 10 meters underground and thermal energy reaction ...... above minus 70 degrees Celsius. And it can realize the synchronization of information with the base vehicle.

Note: This unit does not have the ability to send satellites into space, it needs to be cooperated by the launch unit, and at the same time, it must produce additional launch vehicles, and it also needs to have a ground satellite control center or replace it with a base vehicle.

Suggestion: Aerospace equipment is the mainstream of future development and one of the important military means, and its existence is indispensable.

Li Lan has been pursuing spy satellites for a while, and there is still a lack of weapons and equipment in the current territory, but these things are nothing compared to the importance of spy satellites. Nowadays, there are thousands of satellites in the earth's orbit, all of which are concentrated in the eyes of Shijie first-class countries. Li Lan also wants a piece of the pie, and she also has her own eyes in the sky.

There's an old saying, stand tall and see far. There is no other means of reconnaissance that can be more rapid than satellites. Moreover, if there are no satellites, the satellite communications and navigation equipment of the navy, army, and air force will be completely useless. It's fine to be within the base's 400-kilometer scanning range, but if you go out of this range, it's a big difference. The communications of the three armed services all rely on satellites to transmit them.

The satellites given by the base are not single spy satellites, but also satellites for this kind of scientific and technological experiments. If Li Lan is just a pure war maniac, full of wars that are wars, then these satellites will not be of much use to him. For him, the emergence of spy satellites is also an important help for him to start his aerospace science and technology experiments.

And in addition to spy satellites, these types of satellites that seem to have little to do with war are actually all indirectly related to war. (To be continued......)
