In Yue'an City, countless people took to the streets, raised their heads, and looked up at the sky.
In the sky, warships took off one after another, densely packed, blocking out the sky and the sun, and making people scared.
"With so many spaceships, what are the aliens going to do?!"
“Aren’t you planning to continue immigrating?!”
"Impossible, these spaceships carry a lot of cannons..."
"It seems like there is going to be a war. Who are they going to fight?!"
"In addition to blue stars, is there any other intelligent life in this solar system?!"
The residents fell silent, shocked by the revelation.
In the crowd, Chen Xiao and Zhuge Tao looked at each other with nervous expressions.
"Could it be that the exposed incident happened and they went to destroy Blue Star?!"
"I don't know, maybe I'm going to fight the Universe Federation..."
"With so many spaceships, we shouldn't need them to attack Blue Star, right?!"
The two of them felt that there was a high probability that these spaceships were going to attack the Space Federation.
"Hopefully, the Universe Federation can win..."
……
"Sir, the first wave of strikes has arrived. The main attacks are kinetic energy cannons, electromagnetic guns and rail guns. In addition to ordinary ammunition, there are also some magnetic bombs mixed with them. The diameter is 1cm. It can self-detect the explosion of enemy targets and has a close range of 1 kilometer.
Within, our base can be destroyed..."
"Can it be intercepted?"
"Yes, there are so many magnetic bombs like this. The number of detected bombs alone exceeds 100 million. Using laser interception consumes a lot of energy..."
Laser weapons consume more energy the farther away they are. If you want to have a certain interception capability, some of the energy must be wasted.
Zhao Yu frowned. In space battles, kinetic energy cannons are not considered advanced because there is no air to stop them in the universe, so the ammunition of the kinetic energy cannon has an almost unlimited range and will only stop when it encounters other celestial bodies or physical targets.
Ordinary kinetic energy cannons can be produced by zero-level civilizations, but the kinetic energy cannon launched by the Moro fleet not only utilizes the kinetic energy cannon's unlimited range and low energy consumption when firing, but also adds various types of ammunition.
Ordinary ammunition needs to hit the base point to be effective, but the ammunition with special characteristics is diverse. Some can release the magnetic net when the base point is detected, destroying the internal structure of the base point, and some will automatically hit the enemy unit when it is about to hit it.
Explode into smaller and more numerous fragments.
In this resistance-free environment of the universe, objects with extremely high speeds, even fragments of just a few millimeters, are enough to destroy the base point.
Zhao Yu looked at the data given by Uncle Da and frowned deeper and deeper.
Data shows that it is not cost-effective to use laser defense systems to intercept kinetic energy cannon ammunition.
In addition to competing in technology, space warfare is actually a competition in resources and energy.
In terms of resources, in addition to providing ammunition for various gun muzzles, they are also purified and converted into energy.
The energy conversion core of the Moro fleet is Type 2 particle black hole transmutation, which releases energy with an efficiency and power that is 20 times that of third-generation nuclear fusion.
When converting the same amount of energy, Zhao Yu consumes 20 times more resources than his opponent.
In addition, this war also includes the energy consumption of various weapons and facilities, such as the laser defense system. Assuming that the energy consumed by each intercepted kinetic energy cannon shell is 1,000, then the energy consumed by the kinetic energy cannon shells fired by others
Energy is only 1.
This is equivalent to someone else exchanging inferior horses for Zhao Yu's superior horses. The more lasers are used to intercept, the greater the loss will be.
For Zhao Yu, the loss of resources is secondary. The real key point is the replenishment of energy.
There is an upper limit to the energy released by third-generation nuclear fusion, which is 20 times worse than the enemy's Type 2 particle black hole.
Once the replenished energy cannot keep up with the consumed energy, the base point will be breached, and the entire line of defense will be destroyed.
"Are there other lower-energy ways to intercept these kinetic energy cannons?"
"Yes!"
Uncle Da nodded and said: "Many of our destroyers are also equipped with kinetic energy cannons, which can be used to intercept. However, due to the gap in energy devices, our energy consumption is still 20 times that of the opponent, but the loss is more than 1,000 times that of laser interception.
Be stronger..."
20 times. This is a technological gap. There is no other way. It is best to use kinetic energy cannons.
Zhao Yu nodded and said: "Then let the destroyers intercept these kinetic energy shells. If they are really unable to intercept them, use lasers to intercept them..."
Kinetic energy cannons have obvious advantages and disadvantages. The advantages are unlimited range and extremely low energy consumption. Even a random stone can be used as ammunition to be fired, but it is not as powerful as special ammunition.
But the shortcomings are also obvious. It can only be regarded as a physical strike, and the ballistic trajectory is fixed. It has almost no ability to turn independently. It can be intercepted by calculating the trajectory in advance. At the same time, it will be easily ablated when encountering other energy attacks. p>
Zhao Yu handled the frontline affairs one by one and made sure that there would be no mistakes in the first wave of attacks. Then he relaxed and asked, "Is there anything else?"
"Yes!"
Uncle Da hesitated for a moment and then said: "There are some small moves on Blue Star's side..."
"What little move?!"
"They mobilized public opinion and said that we blocked them and wanted to join the Universe Federation..."
"Cosmic Federation?!"
Zhao Yu was stunned for a moment and frowned: "The message sent by the Moro fleet penetrated the sky and reached Blue Star?!"
"Not sure, we can't rule out that the Moro fleet has this capability..."
Zhao Yu shook his head and said: "Let them make trouble, I don't have time to pay attention now..."
Uncle Da continued: "Sir, they seem to be mobilizing nuclear weapons and preparing to break the sky..."
"Breaking the sky?!"
Zhao Yu was speechless, "The canopy and Blue Star laser defense systems were built to protect them. Are they looking for death because they don't want to live long?!"
It would have been fine if it had been broken before, but now, with the Moro fleet launching a massive attack, any uninterrupted stray bullet hitting the Blue Star would be enough to cause a major disaster.
"How many battleships do we have in Blue Moon?"
"There are not many left. The front line is tight. All the warships that can be transferred have been transferred. There are only five frigates and more than a hundred transport ships left..."
"However, there are quite a lot of space combat robots, as many as 100,000, but they have no way to use nuclear weapons..."
Uncle Da added: "If Blue Star uses a certain point as a breakthrough point, there is a great possibility that the laser defense base point will be consumed..."
"Blue Star nuclear weapons are very powerful inside a planet with air. If they don't intercept, the base point will be damaged. If they intercept it, with their nuclear weapons reserves, the energy consumption of the base point should not keep up with the supply..."
Zhao Yu shook his head, too lazy to think about why Blue Star did this. He had done his best to establish the Blue Star canopy and laser defense system. Now Blue Star has to face the universe directly. It is their own decision, and they will bear the consequences themselves.<
/p>
"Sir, do you want to send frigates over? As long as we send 100 more frigates, we can prevent the sky from being broken..."
"No adjustment, the front line is tight, and there are so many frigate vacancies, there is no need to waste troops in these places..."
Zhao Yu thought for a while and said: "If they want to break the sky, let them break it. Don't worry about Lan Yue's frigate. Just protect our transport ship up and down..."
Looking at the video, many people rushed into the Blue Moon Factory and smashed it.
Although the Blue Moon Factory is in his name, all costs are borne by Blue Star itself. For him, the original purpose is to recover technology points. If it is destroyed, it will not be opened. They should not regret it. p>
In contrast, the resources Xiaotian mines are the top priority at the moment and determine the direction of the war.
Zhao Yu said directly: "Warning Blue Star, no matter what the reason, if our Xiaotian loses one of them in Blue Star, we will fire a Star Destroyer Cannon at the place where their biological activities are the most intensive..."
