Chapter 58 High Cost

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

The appearance of the cargo spacecraft is basically similar to that of the Chang'an, and it also has no nozzle. The only difference is that the external electromagnetic gun turret and nuclear missile launcher are missing.

"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 of the original?" Said in surprise after reading the content of the report.

"Yes, the cost has been greatly reduced, at least much cheaper than 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 the others is about 1.4 times the price of a Ford-class nuclear-powered aircraft carrier if converted into money.

This price is naturally unacceptable on the earth, even if it is a 20-ton freighter, it is less than one percent of that, but as a spaceship, this price is completely reasonable.

As for the cost of Chang'an, it is naturally even more astonishing. At that time, the space dock had not yet been completed, 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 have their own warships. On the one hand, the technology was not up to standard at the time, and on the other hand, the price of warships at this stage is too expensive, and no one is willing to bear it.

"So how do you reduce costs?" Say asked.

"Because there is no need for long-term combat, we removed the Chang'an weapon system and ecological cycle system, and reduced the power of its non-fuel fusion engine. These are the most costly." Vadim explained.

"It means that the template of the cargo spaceship is Chang'an?"

"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 from the design of the Chang'an."

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

"You forgot one thing, speed." Cheng Xin got up and opened the PPT and introduced: "Compared to the speed of Chang'an, the speed of the cargo spaceship can be said to be slow."

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

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

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

"Understood, because this is a castrated version of space battleship, many functions have been omitted, so the energy consumption is also much lower. Can humans now mass-produce cargo spaceships?"

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

Hearing that everyone sitting here was surprised. Although this thing is said to be cheap, it means that compared with the Chang'an, it is actually a super project costing tens of billions.

To put it bluntly, proposing mass production of cargo spaceships is as ridiculous as proposing mass production of nuclear-powered aircraft carriers in the past.

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

"No, no, don't think about the cost. I'm asking whether the production speed of cargo spacecraft can keep up. Can one or even two be produced in a day, just like the US produced aircraft carriers in World War II."

"It's also impossible." Vadim quickly explained: "Because even a castrated cargo spacecraft is still a spaceship, and its design time is about 1-1.5 years."

"And because of the gravity problem, the construction process of the cargo spacecraft must be in the space dock, not the earth, so the cost will soar even more. 1-2 ships a year is the limit speed."

"What makes it more expensive to build a spaceship in space than on earth? Transportation or construction?" Sai asked casually.

"There are both. First of all, the space elevator is an extremely 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."

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

"It means just building more space docks. For example, if humans have thousands of space docks, then on average, nearly ten cargo spaceships can be manufactured a day." Say said.

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

"Why do you say that? Isn't building more space docks the solution?" Say said, turning to Vader who hadn't spoken just now.

"Because building a large number of space docks is an overwhelming project, the human world cannot afford such a huge project." Someone explained
"Compared to Earth, construction operations in space are very difficult. Not to mention the high-intensity temperature difference and radiation effects, just a worker's space-style powered exoskeleton is worth millions of dollars." Vader took the The words of people.

"Actually, it's pretty cheap. The spacesuits used by the astronauts of the Shenzhou spacecraft were much more expensive than this. In the 90s, NASA's spacesuits were as high as tens of millions of dollars. I mean the dollars in the 90s."

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

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

"As for those construction spacecraft, they are just like chips. No country or continent can produce them alone, not even the United States. They can only rely on multinational cooperation." Cheng Xin reminded.

"Then increase the investment first, and reduce the target of the plan by the way, but the cargo spaceship project must be started." Sai said firmly.

"Chairman Say, I suggest that you consider carefully. Building a large number of cargo spaceships is directly robbing the mainstream defense plan for resources, and the three major fleets will definitely give great resistance." Vader persuaded.

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

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

"Chairman Sai, is it your plan to produce cargo spaceships?" An expert suddenly raised his hand and asked.

　In the tenth episode, Taylor almost made a move on the Wall Breaker. To be honest, although I wrote it like this, I didn’t expect the crew to really dare to shoot like this. I look forward to the next plot where Rey Diaz shoots the Wall Breaker
