The battle lasted for a short time, and it was only ten minutes when the battle was full.

However, it took time and effort to clean up the battlefield, and it took four full days before and after to recover all the debris that could be found.

Because it is an item from an unknown civilization, the military immediately activated the isolation protocol, and every piece of debris must be salvaged and transported to implement a strict decontamination system.

It is not the usual kind of decontamination that is sprinkled with disinfectant and the whole thing is done, but a composite decontamination that is repeatedly irradiated with various high-intensity rays to ensure that no unknown alien microorganisms will approach the earth or other living environments related to humans.

As for the extraction and transportation of biological samples, it is a different system.

The place to study extraterrestrial objects is not on Earth, Jupiter, or other places with a risk of spreading, but a temporary space station has been built at the edge of the galaxy, and a group of researchers have been selected to settle in.

However, it is not pleasant to conduct research here, because all research is done remotely through heavy safety glass or simply walls, and researchers are never allowed to come into direct contact with extraterrestrial objects.

To tell the truth, after so many years of development, human beings have long accumulated a lot of experience in the disposal of extraterrestrial objects, and now, all the experience is used on the items of mysterious civilizations.

Due to the eagerness of the military, researchers worked around the clock and quickly came up with preliminary findings.

First, none of the biological samples found any known form of life.

Secondly, more than 30 unknown alloys were found in various fragments, most of which were mainly light elements, containing only a small number of heavy elements, but the mechanical properties were surprisingly good.

Prior to this, humans had been exposed to similar lightweight, high-performance alloys, but they had never been so strong.

The military's research teams that are working on materials are all going crazy.

The original research project has not yet produced results, and so many new materials have been obtained, which is the rhythm of forcing people to death!

Light element alloys have small mass, high strength, and other excellent physical properties, but light alloys are not a good choice, because the military must first consider the content of those light elements on the earth, and also consider the cost of mining and use.

This thing was only researched to facilitate interstellar immigration, and to go to those planets that are not rich in heavy elements.

The same is true for other types of alloys, the military's goal is to find the right recipe to create a qualified warship, regardless of the proportion of elements contained in the target planet.

This is not an easy task, and so far the military has had very limited formulas of light alloys, counting them on one hand.

This conflict provided enough samples for the researchers, but no one can guarantee when the results will be available - the recipe is only the foundation, the process is the key!

Although the researchers are all veterans in the industry and are familiar with the various smelting processes they know, the new materials come from alien civilizations, and the ghosts know what special processes the aliens don't know.

Then again, you don't have to know smelting technology to make a qualified alien alloy.

In the early years, the Luojianshan base conquered atomic-level 3D printing technology, as long as you know the formula ratio of the alloy, and then figure out the microstructure of the alloy, you can print the required alloy at the atomic level through 3D printing technology. ….

It's time-consuming and laborious, but it's much better than staring at it and not being able to make it.

Also because of the decisive breakthrough in 3D printing technology, various types of 3D printers are popular, and the high-end manufacturing industry is almost completely monopolized by the heavy-duty 3D printers produced in Luojian Mountain.

The cost of this thing is indeed relatively high, but compared with the traditional manufacturing method of cutting and cutting, it has an advantage, and it is at least half the cost.

Take the battleship as an example, there are strict requirements for the cutting and forming of each steel plate, not that there can be no mistakes, but the faulty steel plates are never allowed to be installed on the battleship.

Printing is different, directly out of the finished product, basically no scrap rate.

Originally a battleship, which could be printed from beginning to end, from

The skeleton and the shell are all formed in one piece, leaving no gaps.

Once upon a time, such a battleship almost became the main model of the military.

But if you think about it, is it really good to be molded in one piece?

In terms of intensity, yes.

But from a usage point of view, there are more disadvantages than advantages.

The most troublesome point is the maintenance problem, even if the traditional battleship is broken, as long as the damaged module is replaced, the battleship will immediately be reborn.

How to change the one-piece molding? Cut out the problematic part and replace it with a new module?

Isn't this just taking off your pants and farting?

Therefore, the military vetoed the one-piece molding scheme and changed it to an all-in-one module.

In other words, the two heavy-duty 3D printers that cost a lot of money to print warships directly are useless, and are replaced by medium-sized printers that are much smaller in size, much less expensive to use, and not much less effective.

Sometimes, the more advanced the better, and it is necessary to take into account all other issues and use the method and purpose comprehensively to arrive at the best solution.

Therefore, the current main warships are modular, but the military has great expectations for light element alloys, and after the research team has thoroughly understood the microstructure of the new alloy, the military immediately conducted an unprecedented comparative experiment.

The test subjects were two Meteorite-class warships, one made of pure light element alloys and the other an active warship.

The internal structure and dimensions of the hull are identical, with the only difference being the material.

After the start of the experiment, the two warships carried out experiments on speed, firepower, endurance, and resistance to strikes.

It turned out that, under all things being equal, the endurance of the Light Elemental Battleship was a quarter higher than that of the active campaign, and the consumption when jumping was much smaller.

The same goes for regular sailing conditions,

No way, with the same size structure, a battleship dominated by light element alloys is more than thirty percent lighter than a standard battleship.

The results of other comparisons are also out, and the approximate situation is that the cost will increase by 20%, the maintenance cost will increase by 35%, and the daily maintenance cost will also increase by 12%.

In other words, the use of light element warships is equivalent to exchanging cost for combat effectiveness.

But then again, as long as the combat effectiveness is improved, what is the point of adding some costs?

The content of some light elements on the earth is indeed not high, but the content of other civilizations on the planet is not low, and it is completely possible to import light elements in large quantities through trade to offset the increased costs.

In this way, the cost can also be reduced, so why not?

In this way, the Meteorite, which has only built a few dozen ships, ushered in its first large-scale improvement, and the improved model has a new codename: the Comet Star!.
