A large ship with nine small ships lined up in the void not far from the fleet's station. Pen ~ fun ~ pavilion www.biquge.info

This scene is naturally not a big scene on the scale of the universe, but Zhou Chen's heart is surging.

Thousands of tall buildings rise from the ground, this is his fleet!

After calming down, Zhou Chen sat back on the command seat and gave an order with a calm expression, asking Dandan to report the relevant data of the current Earth Fleet.

"Yes!" The white robot projected in the void nodded, and then a large three-dimensional screen appeared next to it, showing the projection of various ships and related parameters.

"At present, the Earth Fleet has a total of 12 warships in formation, of which the 'Lanqiong', 'Meteorite', and 'Poseidon' are comprehensive ships, and the remaining nine are auxiliary ships, with the apparent parameters of the comprehensive ship: 15.65 kilometers long, 7.8 kilometers wide, and 5.2 kilometers high, which are divided into a comprehensive storage area, a comprehensive living area, a comprehensive support area and a composite power area, and are equipped with 325 fixed defensive weapons."

"The apparent parameters of each auxiliary ship: 7.24 kilometers long, 3.9 kilometers wide, and 3.1 kilometers high, are also divided into a comprehensive storage area, a comprehensive living area, a comprehensive support area and a composite power area, and are equipped with 75 fixed defensive weapons."

"At present, the flagship 'Lanqiong' and nine auxiliary ships have been repaired and can be put into use at any time. The other two large capital ships, the Meteorite and the Poseidon, are still under repair......"

The main ships of the fleet and the many engineering ships responsible for the construction of the base in the garrison are counted separately, and although they are also the creations of scientific and technological civilization, the scientific and technological content involved is very different. Therefore, Dandan's report only mentions the fleet's capital ships.

"And what about the station?" Zhou Chen asked.

"Returning to the commander, at present, the station has completed the layout and construction of the primary industrial system, and the energy side has achieved a balance between supply and demand in the short term."

"At present, there are a total of 900,000 special robots for various types of construction and maintenance in the station, which can complete various types of construction and hull maintenance tasks; In addition, about 70,000 immovable construction engineering smelting robots have been deployed, which can provide various raw materials required for construction to the station, and a total of 978,000 robots will participate in the construction of the station. And has built more than 200,000 exploration and mining robots of various types, and more than 30,000 large transport ships! It can basically ensure the material needs of the current station. ”

These are the current home of the Earth Fleet station, and through the almost crazy explosion some time ago, the planning of the primary industrial system of the Earth Station has been basically realized.

Zhou Chen nodded to show that he understood, and he couldn't help but feel that "science and technology are productivity" in his heart. Just imagine that the primary industrial system has such a huge construction capacity, so what kind of grand picture should it be for the intermediate and advanced levels!

Of course, the reason why the construction speed of the station is so fast has a lot to do with the relatively low scientific and technological content of the various construction tasks in the station. Strictly speaking, these supporting facilities do not have much technical content, but they achieve a certain degree of intelligent control and integrate them intensively.

For Dandan, who is at the level of a third-level civilization, building an industrial cluster of this scale is just a part of the computing power.

However, it is precisely because the technology content of these robots and engineering transport ships is not high, so Zhou Chen knows that their ultimate fate is very sad. If there are no accidents, these robots will be abandoned when the Earth fleet leaves the solar system, because sailing with them will only slow down the evacuation progress of the entire fleet.

This has to be regretted.

"In addition, the 'civilization-class' ships currently under construction include: five civilization-class warships and five large residential ships, and the construction period of each ship is expected to be three years." Dan Dan then reported.

Compared with other facilities in the station, which can be completed in a few days or dozens of days, the construction of the Civilization-class battleship takes three years, which is really a bit impressive.

This is a very stark contrast, and it also reflects from the side how difficult it is to build a Civilization-class warship.

Of course, the construction cycle will naturally be different depending on the technological content, and for civilization-class ships, the three-year construction cycle is actually not long at all.

For example, the large habitation ship under construction draws on the shipbuilding experience of the Odo civilization and is designed as a disc-shaped spaceship with a diameter of 30 kilometers and a center height of 10 kilometers. It's a behemoth, right?

The entire spacecraft is divided into two parts, the upper and lower parts according to the different functional blocks, which are the living area located in the upper part and the support area located in the lower part.

Among them, the support area is where the power system, protection system and ecological maintenance system of the living ship are located, accounting for nearly one-third of the longitudinal height of the whole ship. When the habiting ship follows the fleet for interstellar voyages, its role is mainly to create a stable environment suitable for life survival and activities in the ship.

The residential area, as the name suggests, is a residential area, which accounts for two-thirds of the longitudinal height of the whole ship, with 500 meters as a floor, divided into 14 floors, according to the calculation of 500,000 people living on each floor, the whole ship can carry a total of nearly 7 million people.

According to the scale of the evacuation of 300 million people, it means that the entire Earth fleet needs to build at least forty-five habiting ships of this type to meet the demand.

Due to the large size of this kind of ship, it is necessary to adopt long-span components in the construction process, and the mass of these single components can easily reach tens of thousands of tons, or even hundreds of thousands of tons, plus the huge inertial stress that the spacecraft has to bear when flying at high speed.

In order to ensure that the hull is not deformed and does not fall apart, it is required that special alloy materials with strong bearing capacity must be used in the construction!

Calculated on just one habitable ship, the consumption of this super special alloy for the construction of the whole ship has reached about 24 trillion tons!

What kind of concept is this? You must know that China's annual steel output is only 11 trillion tons.

This means that, without considering the difference in steel, even if it is built entirely of crude steel from the earth, the steel needed for a habitable ship would need to be smelted continuously by China for more than two years at its existing steelmaking capacity to be supplied.

Counting the difference in steel, different processes need to be added, and China needs to smelt continuously for ten years to obtain the steel materials needed to build a habitable ship. And China's steelmaking capacity accounts for more than half of the world's steelmaking, in other words, the world's large-scale steelmaking in ten years is only enough to build less than two residential ships.

This is a very scary thing! It takes five to six years to build a habitable ship just by providing steel, and if you add up the construction period of about 20 years, the entire construction period of a ship will take about 25 years.

This is still not considering the social effect, as well as the premise of supporting lifting and hoisting equipment, if it is taken into account, it is bound to be delayed!

In addition, about 40 billion kilometers of cables are needed inside a habiting ship (taking 1,000 kilometers of cables used by an aircraft carrier as a reference), Zhou Chen suddenly found that even if the most complex power system is not involved, he completely handed over the construction drawings of the habiting ship to the countries on the earth, and they may not be able to build it.

In the gravity-free environment of space, the deformation caused by the gravity of the steel and the difficulties that may arise when hoisting and placing can be ignored. But even then, it would take almost three years to build a habitable ship at the Earth Fleet station.

Unwillingly, the strength is not enough, and the technology is not enough!

What's more, a simple habitation ship cannot survive in the universe, it must also be mixed with the corresponding supporting ships, according to the plan given by Dandan, the entire earth fleet will form a "5:5:5:5:5" mixed formation mode in the future, in addition to the need for five residential ships, a formation must be equipped with five civilization-class warships, five supply ships, five engineering ships of various types, and five scientific experiment ships.

This is the best match model to maintain a civilization's survival in the universe!

At present, the construction of five residential ships and five civilization-class warships has been started in the station, which means that there are still five supply ships, five engineering ships of various types, and five scientific experiment ships that have not yet started construction before the completion of a mixed formation.

In the future, the Earth Fleet will have at least nine such formations in order to meet the needs of 300 million evacuees, so you can imagine how much pressure it is facing.

"The revolution has not yet succeeded, comrades still need to work hard!" Zhou Chen couldn't help but sigh.

Among all the ships, the most material-consuming is the habituating ship, and the most technological is undoubtedly the civilization-class battleship.

Although the Civilization-class warship is nowhere near the size of the habitation ship, its military use will only have a more complex internal structure, which greatly delays its construction.
