Homo sapiens

September 11th.

The disturbances from the outside world did not affect Li Qingye's daily work.

He was currently in the Hugang Basin of the Hongsawady Branch.

As one of the five aerospace cities that Homo sapiens has invested in.

Compared with the other four space cities, the military style here is stronger.

Wu Feng, who was previously in charge of the Langerang Mountain Base, was recently transferred here to be responsible for the management of this aerospace city.

In addition, people from the Space Division and the External Security Division also appeared here.

Mang Qingshan, who was dispatched by the External Security Division, explained to him: "Chairman, this is the Feathered Serpent Corps we recently formed."

"How do you train?" Li Qingye was a little curious. He knew about the formation of the Feathered Serpent Corps by the External Security Division. After all, such a major event must have his approval.

Mang Qingshan is the person in charge of the corps. When he heard the question, he quickly replied: "We cooperated with the Space Division and borrowed part of the astronaut training facilities. As for actual combat training, there is currently no way."

"I heard that the External Security Division is revising its previous plan recently?"

Mang Qingshan nodded: "Yes, it is because of the emergence of new technologies and technical adjustments."

"What part was adjusted?"

"Previously we planned to use the space shuttle to take off from the ground, but now we have modified it to take off at a position of 30,000 meters in the stratosphere."

Li Qingye's eyes flashed with clarity: "Vacuum airship platform?"

"Yes, when taking off in the middle of the stratosphere, the atmospheric resistance will drop by about 15 times, and the distance to the Kármán line will only be 70,000 meters, which can meet the needs of large-load space shuttles entering and exiting the atmosphere."

Li Qingye touched the stubble on his chin, and then ordered: "Take a look at the plans of the External Security Division."

"Please wait a moment, I will arrange it right away."

After a while, Mang Qingshan called up an internal planning document of the External Security Division and projected it on the holographic device.

There are not only various planning plans, but also many conceptual models and scenarios.

Specifically, it is to build an airship platform that is about the same size as the Dandelion airship, but with twice the vacuum volume. The platform will have a vacuum volume of 4 billion cubic meters.

At an altitude of 30,000 meters, the airship will have 40,000 tons of buoyancy, minus the weight of 10,000 tons of supporting facilities, and the remaining 30,000 tons of buoyancy will be used to carry the space shuttle.

To be precise, it is not a space shuttle, but an aerospace fighter and an aerospace transport aircraft.

The Quetzalcoatl Legion is the department responsible for managing the space carrier, and it is also a special security force, because the Quetzalcoatl Legion has three orbital airborne regiments that can land from suborbital airdrops to any area of ​​the earth.

As for why this is unnecessary.

The reason for the External Security Division is to avoid the airspace of other regions.

Airspace in the usual sense refers to the airspace below the Karman Line. Suborbitals and low-Earth orbits above the Karman Line are all international public areas and can be passed freely without the permission of other forces.

In other words, those inland areas actually have a "coastline", and that coastline is the Karman Line at a height of 100 kilometers.

If the Homo sapiens company wants to "invest" in the Mobei region, it must pass through Lucia or the Far East if it uses traditional transportation methods.

But if a suborbital route is adopted, the Homo sapiens company will not need to pass through Lucia and the Far East, and naturally it will not need the permission of the other party.

In this case, Homo sapiens companies can use the concept of "cosmic sea" to radiate their influence to inland areas and carry out various "investments."

Li Qingye looked at the cost again.

Among them, the total cost of the Space Carrier Type 2 is estimated to be 520 million gold dollars per unit.

An air and space fighter costs 7.5 million gold dollars.

An air and space transport aircraft costs 38.6 million gold dollars.

A set of orbital airborne troop armor costs 80,000 gold dollars.

In terms of operating costs, the space carrier uses a nuclear reactor, and the energy consumption cost is 6 million gold dollars in 50 years.

Aerospace fighters and aerospace transport aircraft use methane and liquid oxygen engines, and the fuel cost of a single flight is only about one-thirtieth of that of ground launch.

Li Qingye saw five aerospace aircraft designed by the External Security Division and the Ministry of Space.

One of the aerospace transport aircraft with a payload of 2,000 tons has a dead weight of 1,200 tons, but only 3,000 tons of methane and liquid oxygen.

If it were launched from the ground, it would require at least 60,000 tons of methane and liquid oxygen to send a 3,200-ton payload into suborbital space.

Launching at high altitude can indeed save a lot of fuel and effectively reduce operating costs.

As long as it enters the suborbital area, it can easily fly over the target and then drop the 2,000-ton payload.

These 2,000 tons of payload will be landed using a method similar to launch vehicle recovery technology. It can be a special aerospace container, a specialized airborne force, or simply a large number of bombs.

In fact, a solid-fuel rocket launched in suborbital space can easily reach more than ten times the speed of sound with the help of gravity acceleration.

You can even use an electromagnetic gun directly to launch tungsten steel rods at the target ground.

When one is condescending, there are too many methods that can be used. Even if one throws a steel ball, it will be as powerful as a bullet.

The purpose of the establishment of the Quetzalcoatl Legion is to enhance the mobile security force of the Homo Sapiens Company in suborbital space, and at the same time, it is also taking advantage of existing rules to exploit loopholes.

The cost of launching a 2,000-ton payload into suborbital space is actually 3,000 tons of methane and liquid oxygen. The cost is about 40,000 gold yuan, with an average transportation cost of 50 gold yuan per ton of payload.

The cost is not too high, but it is not cheap either.

But for some closed inland areas, the transportation cost of 50 gold yuan per ton is acceptable.

For example, if you transport some emergency supplies, special equipment, important items, etc., you can use this method to get them there quickly.

Li Qingye understands the thinking of the External Security Division.

They should have considered that the Homo sapiens company would "open branches" in other regions in the future, and did not want to waste time with other forces along the way, so they promoted suborbital transportation and suborbital airborne.

After all, the relationship between Homo Sapiens Company and many regions is not very good now.

Even parties in Africa, South America, and West Asia that cooperate with Homo sapiens on the surface are secretly very wary of various investments made by Homo sapiens companies in their territories.

This is mainly because the Homo sapiens company has a history of forcibly establishing full-power branches in some areas. This behavior is obviously unacceptable to most forces.

If Homo sapiens were not powerful enough, the great powers would have formed a coalition to take down the Homo sapiens company.

Therefore, it will definitely not be easy to pass through the airspace of other regions in the future. The forces along the way will definitely be very wary of the Homo sapiens air force entering their territory.

You can't fight all the way through, right? If you really do this, it will be like making a meal of dumplings just for a dish of vinegar, which is a bit outweighing the gain.

Li Qingye didn't say anything about this. It's a good thing that the External Security Division has this kind of strategic thinking.

The development and progress of technology will inevitably lead to innovations in tactics and strategies.

There is no need for the External Security Division to follow the rules too much. Just like when America developed information warfare, it was because of the military changes brought about by the development of information technology.

Now Homo sapiens are also exploring new tactical strategies to take full advantage of new technologies.

Suborbital, a special interstellar public area, was previously beyond the reach of technology. Many forces had no way of utilizing it and could only do some theoretical research.

Now Homo sapiens needs to lead the times and develop a new model.

He finished reading the internal documents of the External Security Division: "Wu Feng, put it away! Let's go to the training base and take a look."

Wu Feng quickly turned off the projection and ordered his assistant to clean up the traces of the document.

He took Li Qingye to the training base for the suborbital airborne troops.
