The moon base I built was exposed

Chapter 30 Discovering Asteroids

"Sir, Xiaotian has successfully received the resources from the earth, do you want to build all the star destroyers?"

After pondering for a moment, Zhao Yu asked, "Can the Star Destroyer Cannon be installed on a U-shaped spaceship?"

"Yes, but with it installed, it will be difficult to install other weapons. In addition, I do not recommend that you install the Star Destroyer on the battleship..."

"How to say?"

"The Star Destroyer Cannon is very powerful and fast, but it also has two shortcomings..."

"One, it takes a long time to start, and it takes a long time to brew..."

"Second, it can only strike fixed targets. If it encounters other spaceships, it will be difficult to lock on..."

Zhao Yu nodded slightly and asked, "What weapons can be installed on the U-shaped spaceship?!"

"Laser cannon, plasma cannon, kinetic energy cannon..."

"The laser cannon's attack speed is very fast, reaching the speed of light, but because of the principle of diffraction, its power will decrease with distance. Unless the power generation power is increased, the current technology has a maximum range of only 1000 million kilometers. In the cosmic environment , the effect is limited..."

The closest distance between the moon and Mars is more than 5000 million kilometers. Using laser cannons to strike long-distance targets cannot even hit the doorstep.

"In addition, the laser cannon is limited by its caliber, and its attack range is not large. Even if it really hits a space battleship, excluding other factors, if it hits it with one shot, it will at most make a small hole in the battleship..."

However, the laser cannon is very useful as a defensive facility, and the original disadvantage has become an advantage.

For example, it can fly at the speed of light, the closer the distance, the stronger the power, etc.

Zhao Yu's moon base has more than half of its defense systems, all of which are based on laser cannons.

Uncle Da paused for a moment, and then said: "Plasma cannon uses lasers to heat deuterium to a high temperature of one million degrees to make it into an ion state, and then uses electromagnetic technology to launch it. Its range is not as good as laser cannon..."

"Compared to the first two, the kinetic energy cannon has more advantages in terms of attack..."

"Compared to laser cannons, using kinetic energy cannons, in the cosmic environment, can be said to have infinite range..."

"It's just that the power of the kinetic energy cannon is not great. This is not only its shortcoming, but also its advantage."

"Our existing kinetic energy guns mainly include rail guns and coil guns..."

"The shells fired by the railgun are in frictional contact with the orbit, and the power will also decrease with distance, but the advantage is that the rate of fire is high, the shells are very light, and the initial velocity will be very fast. It is very important to fight against warships in space Advantage……"

"The coil gun is slightly more powerful than the rail gun, and it can also be used as a common weapon for battleships..."

While explaining, Uncle Da projected a three-dimensional image, presenting the advantages and disadvantages of various weapons.

Among the four weapons, the most powerful one is the laser cannon. It is fired at close range, and there is almost no chance for the enemy to dodge. However, the rate of fire is limited. There is an interval between each cannon, and it takes up a lot of space. The same area, install a Laser cannons, ten railguns can be installed.

Compared with laser cannons, plasma cannons have more advantages when facing electronic products.

The other two kinds of kinetic energy guns are more flexible, and any rail gun can achieve a hundred shots per second.

The disadvantages are also obvious, the power is limited, the shells are very small and light, mainly to destroy enemy warships.

Uncle Da thought for a while, and then said: "In addition, regarding the situation of fighting other warships in the universe, I used the existing data to simulate..."

"What the actual combat situation is like, I don't know yet!"

Lacking actual combat experience, he doesn't know which aspect of data is the most important in space warfare.

Of course, the main reason is that there is no physical warship on hand, and I don't know what the configuration is on it.

Camouflage, stealth, detection, locking, etc., any item that pulls the hips may be destroyed by the enemy.

Zhao Yu glanced at the time when the system first warned of the arrival of the alien fleet, and there were still two months and ten days left.

Now, he also wants to understand that the alien fleet definitely does not refer to the earth, because when the title system appeared, it was clearly stated that the earth was his original planet.

So, before that, he needs to be ready to deal with the alien fleet.

As far as the moon base is concerned, its defense capabilities have been achieved to the extreme.

Zhao Yu believes that as long as a planet does not come to serve as a backup for civilizations of the same level, otherwise it is impossible to break through with the firepower of the fleet alone, no matter if they are a hundred or a thousand ships.

The only thing to do now is to increase active attack methods, such as various types of space battleships.

"Then build two more Star Destroyer Cannons, and the others are mainly ship-mounted laser cannons, ship-mounted plasma cannons and ship-mounted kinetic energy cannons..."

……

Association for the Exploration of Extraterrestrial Civilizations.

The association did not participate in this feast of curses.

After all, they are astronomy enthusiasts, and they prefer to focus on the universe rather than scolding people.

On this day, a member of the association discovered an asteroid in the dark universe.

He immediately followed up.

"The diameter is estimated to be 50 kilometers..."

"Start trajectory calculation..."

"The calculation failed, the speed is too fast..."

After thinking about it, the member uploaded the data to the Great Xia Space Agency.

"I hope this asteroid will not be captured by the eight major planets, so that it can be named after me..."

……

Bactria Space Agency.

These three days, they were also very busy, helping Chief Engineer Yang to think about cursing, communicating with colleagues in other departments, and synchronizing data to the United Earth Defense Bureau, etc.

Sun Mingyuan was doing routine work when he suddenly received an email from the non-governmental organization Association for the Exploration of Extraterrestrial Civilizations.

Their space agencies generally have certain connections with these folk astronomers.

At least half of the unknown signals in the universe come from folk enthusiasts.

Therefore, after seeing the email, Sun Mingyuan was not surprised, so he opened it casually.

"Huh? Asteroid?"

"50 kilometers in diameter..."

After thinking about it, he began to use the high-end equipment of the space agency to calculate the trajectory.

"Running track..."

"There is a 0.01% chance of hitting the Earth..."

"This!"

The chance of one in [-] is not small, and Sun Mingyuan quickly reported the situation of the asteroid.

　I wrote a chapter and it was blocked. I don’t know which paragraph is wrong. I was afraid that the unblocking review would fail, so I simply replaced it and skipped the plot that might be blocked.
