Cheng Xin's efficiency was not low. In just a few weeks, she and the people from the relevant departments gave Sai a report, which provided a model of the cargo spacecraft.

The appearance of the cargo spaceship is basically the same as that of the Chang'an. It also has no nozzle. The only difference is that it lacks the external electromagnetic gun turret and nuclear missile launcher.

"So, the cost of this kind of cargo spacecraft is only one-tenth of the Chang'an, but the transportation volume can be increased to five times the original?" Sai was surprised when looking at the contents of the report.

"Yes, the cost has been greatly reduced, at least much cheaper than the Chang'an, but it still requires a staggering amount of money. Of course, considering the increase in the number of space docks in the future, it may be reduced." Cheng Xinhui reported.

According to the report, the cost of the cargo spacecraft designed by Cheng Xin and others, if converted into money, is approximately 1.4 times the price of a Ford-class nuclear-powered aircraft carrier.

This price is naturally unacceptable on earth, even for a 200,000-ton cargo ship, it is less than one percent of the price, but as a spaceship, this price is completely reasonable.

As for the cost of the Chang'an, it was naturally even more staggering. The space dock had not yet been completed at that time, so the cost of building this thing was no less than the Soviet-American space race during the Cold War.

Therefore, the three major fleets do not yet have their own warships. On the one hand, the technology was not up to standard at the time, and on the other hand, the current warships are too expensive and no one is willing to afford them.

"Then how do you reduce costs?" Sai asked.

"Because there is no long-term combat requirement, we removed the Changan's weapon system and ecological circulation system, and reduced the power of its non-working fusion engine. These are the bulk of the cost." Vadim explained.

"I roughly understand it. It means that although we now have a space elevator to enter space, if we want to build something in space, for example, it would be very difficult for Ray Diaz to dig an ultra-deep well before."

"You want to mass-produce cargo spaceships?!"

"Yes, because the extraterrestrial environment is too harsh and the equipment coefficient requirements are too high, even now, only China and the United States have the technology to produce powered exoskeletons for space operations."

"No, no, no, don't think about it in terms of cost. I'm asking if the production speed of cargo spaceships can keep up. Can we produce one or even two cargo ships in one day, just like the United States produced aircraft carriers in World War II?"

"I understand, because this is a castrated version of the space battleship. Many functions have been omitted, so the energy consumption is also much lower. So can humans now mass-produce cargo spacecraft?"

"This is also impossible." Vadim quickly explained: "Because even the castrated version of the cargo spacecraft is still a spaceship, and its design time is about 1-1.5 years."

"Secondly, the space environment is too harsh. This harshness refers to all aspects. It is also very difficult to build a space dock to produce cargo spacecraft."

"It has both. First of all, the space elevator is an incredibly expensive project. Although the transportation cost of the space elevator is theoretically lower than that of an airplane, this is not the case if the construction cost of the space elevator is included."

"What makes building a spacecraft in space more expensive than on Earth? Transportation or construction?" Sai asked casually.

To put it simply, proposing the mass production of cargo spacecraft is as funny as proposing the mass production of nuclear-powered aircraft carriers in the past.

"No, its volume is much larger than the Chang'an. Considering the transportation operation, even the internal structure is completely different. We just borrowed a little bit of the Chang'an's design."

"When the Chang'an is propelled at full power, it can reach twenty times the third speed of the universe, but the speed at which the cargo spacecraft is propelled at full power is only one-tenth of that."

"Well, considering the cost, this is impossible." Cheng Xin weakly wanted to say something, but was directly interrupted by Sai.

"Then we will first increase investment and reduce the target of the plan, but the cargo spacecraft project must be started." Sai said decisively.

"And because of gravity issues, the construction process of the cargo spacecraft must be in the space dock, not on the earth, so the cost will soar. 2-3 ships a year is the ultimate speed."

"It means just build more space docks. For example, if humans have thousands of space docks, then on average they can build nearly ten cargo spaceships a day," Sai said.

"Because building a large number of space docks is a huge project, the human world cannot afford such a huge project," someone explained.

"Compared to the earth, construction work in space is very difficult. Not to mention the high temperature difference and radiation effects, just one worker's space-style powered exoskeleton is worth millions of dollars." Vader took the piece.

The words of man.

(Since there is no medium resistance in space, the engine power determines the acceleration, but acceleration requires fuel consumption, so the spacecraft must have a speed limit)

"You forgot one thing, speed." Cheng Xin stood up and opened the PPT and introduced: "Compared to the speed of the Chang'an, the speed of the cargo spacecraft can be said to be a turtle speed."

"Why do you say that? Isn't building more space docks the solution?" Sai said, turning away from Vader who had just been silent.

"You are very humorous." Wade, who had been silent all this time, suddenly smiled.

"As for those construction spaceships, they are just like chips. No country or even continent has the ability to produce them alone, not even the United States. We can only rely on multi-country cooperation." Cheng Xin reminded.

"It means that the template for the cargo spacecraft is the Chang'an?"

"Then why can the engine power be reduced even though the size is several times larger?" Sai asked again.

"Actually, this is quite cheap. The space suits of the Shenzhou spacecraft astronauts used to be much more expensive than this. In the 1990s, NASA's space suits cost tens of millions of dollars. I mean the U.S. dollars in the 1990s."

"Moreover, maintaining the ecological cycle and maneuvering combat objectives require additional energy, but the cargo spacecraft does not need these two, and the output power of the engine can be compressed."

Everyone sitting here was shocked when they heard this. Although this thing is said to be cheap, that means that compared with the Chang'an, it is actually a super project costing tens of billions.

"Chairman Say, I suggest you think carefully. Building a large number of cargo spaceships will directly compete with the mainstream defense plan for resources. The three major fleets will definitely provide great resistance." Vader persuaded.

Of course, he didn't know whether he wanted to appreciate Sai's despair or simply wanted to persuade Sai.

"You don't need to worry about this. I will communicate with the three major fleets and the nine major council members. What you need to consider is how to increase the production of cargo spacecraft." Sai rejected Vader's "persuasion".

"Chairman Sai, is your plan to produce a cargo spacecraft?" an expert suddenly raised his hand and asked.

In the tenth episode, Taylor almost attacked the Wall Breaker. To be honest, although I wrote it this way, I didn't expect the crew to actually shoot it like this. I look forward to the next plot where Ray Diaz destroys the Wall Breaker with one shot.
