"Sir, Xiaotian has successfully received resources from the earth. Do you want to build them all into star destroyer cannons?"
After Zhao Yu pondered for a moment, he said: "Can the Star Destroyer Cannon be installed on a U-shaped spacecraft?"
"Yes, but if it is installed, it will be difficult to install other weapons. In addition, I don't recommend that you install the Star Destroyer Cannon on the battleship..."
"How to say?"
"The Star Destroyer Cannon is very powerful and fast, but it also has two shortcomings..."
"First, it takes a long time to start up, and it takes a long time to brew..."
"Two, it can only hit fixed targets. If it encounters other spacecraft, it will be difficult to lock on..."
Zhao Yu nodded slightly and asked: "What weapons can be installed on the U-shaped spacecraft?!"
"Laser cannon, plasma cannon, kinetic energy cannon..."
"Laser cannon has a very fast attack speed, reaching the speed of light, but due to the principle of diffraction, its power will become smaller with distance. Unless the power generation power is increased, the current technology has a maximum range of only 10 million kilometers. In the cosmic environment , the effect is limited..."
The closest point to the moon and Mars is more than 50 million kilometers away. Using laser cannons to hit long-distance targets cannot even hit the doorstep of your home.
"In addition, the laser cannon is limited by its caliber and has a limited attack range. Even if it really hits the space battleship, excluding other factors and hitting it with one shot, it will at most make a small hole in the battleship..."
However, laser cannons are very useful as defensive facilities, and their original shortcomings have turned into advantages.
For example, it can fly at the speed of light, and the closer it is, the more powerful it is, etc.
Zhao Yu's lunar base has more than half of its defense systems, which are mainly based on laser cannons.
Uncle Da paused for a moment and then said: "The plasma cannon uses lasers to heat heavy hydrogen to a million degrees high temperature, turning it into an ion state, and then uses electromagnetic technology to launch it. Its range is not as good as that of a laser cannon..."
"Compared to the first two, kinetic energy cannons have more advantages in attack..."
"Compared to laser cannons, using kinetic energy cannons can be said to have unlimited range in the cosmic environment..."
"It's just that the kinetic energy cannon is not very powerful. This is both its shortcoming and its advantage."
"Our existing kinetic energy guns mainly include rail guns and coil guns..."
"The rail gun's shells are in frictional contact with the track, and the power will also decrease with distance. However, the advantage is that the rate of fire is high, the mass of the shell is very light, and the initial velocity will be very fast. It is very useful in fighting battleships in the universe. Advantage……"
"The power of the coil gun is slightly greater than that of the rail gun, and it can also be used as a common weapon on battleships..."
While explaining, Uncle Da projected a three-dimensional image, showing 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 gives the enemy almost no chance to dodge. However, the rate of fire is limited. There is an interval between each cannon. It also takes up a lot of space. In the same area, one can be placed. Laser cannon, ten railguns can be placed.
Plasma cannons, compared to laser cannons, have more advantages when facing electronic products.
The other two types of kinetic energy cannons are more flexible. Any railgun can fire hundreds of rounds per second.
The shortcomings are also obvious, the power is limited, the shells are small and light, and they are mainly used to destroy enemy warships.
Uncle Da thought for a while and then said: "In addition, regarding the situation of fighting with other battleships in the universe, I simulated it based on the existing data..."
“We don’t know what the actual combat situation will be yet!”
Lacking actual combat experience, he didn't know which aspect of data was 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 one of them may be destroyed by the enemy.
Zhao Yu took a look at the system's first warning of the alien fleet's arrival. 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 native planet.
Therefore, before that, he needs to be prepared to deal with the alien fleet.
As for the lunar base, its defense capabilities have been achieved to the extreme.
Zhao Yu believes that civilizations of the same level, as long as a planet does not come over to provide backup, will not be able to break through simply with the firepower of the fleet, regardless of whether they have a hundred ships or a thousand ships.
The only thing to do now is to add active attack methods, such as various types of space battleships.
"Then build two more Star Destroyer Cannons, and the others will be mainly ship-based laser cannons, ship-based plasma cannons and ship-based kinetic energy cannons..."
…
Association for the Exploration of Extraterrestrial Civilizations.
The association had no part in this curse-fest.
After all, they are astronomy enthusiasts, and they prefer to focus on the universe rather than curse.
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 was too fast..."
After thinking about it, this member uploaded the data to the Daxia Space Agency.
"I hope this asteroid will not be captured by the eight planets, so that it can be named after me..."
…
Daxia Space Agency.
They were also very busy these three days, helping Chief Engineer Yang think of curse words, communicating with colleagues in other departments, synchronizing data to the United Earth Defense Agency, etc.
Sun Mingyuan was doing his routine work when he suddenly received an email from the non-governmental organization Association for the Exploration of Extraterrestrial Civilization.
Their space agencies generally have certain connections with these private astronomy enthusiasts.
At least half of the unknown signals in the universe come from civilian enthusiasts.
Therefore, after seeing the email, Sun Mingyuan was not surprised and clicked it.
"Huh? Asteroid?"
"50 kilometers in diameter..."
After thinking about it, he began to use the space agency's high-end equipment to calculate the trajectory.
"Trajectory..."
"There is a 0.01% chance of hitting the earth..."
"this!"
The chance of one in ten thousand is not small, so Sun Mingyuan quickly reported the situation of the asteroid.
