My Black Tech Shelter

The direct distance from Blue Star to Mars is 55 million kilometers at the closest position and 400 million kilometers at the farthest distance.

The maximum sailing speed of the asteroid-class cargo spacecraft is 400km/s, and the flying speed of the Hummingbird-class destroyer is 550km/s.

This means that an asteroid-class spacecraft can fly from Blue Star to Mars in only ten days at the longest and only one and a half days at the shortest.

The time for a Hummingbird-class destroyer is one to eight days.

Compared with comet-class spacecraft, this speed has been qualitatively improved.

At this time, it is April 1, 2022. Mars is 1.8 astronomical units away from Blue Star, which translates to 270 million kilometers.

Then even an asteroid-class cargo spacecraft can return from Mars to Blue Star in only seven days, and a Hummingbird-class destroyer can return to Blue Star in only five days.

And at this time, Jupiter is only about 4.5 astronomical units away from Mars, which is 700 million kilometers.

However, Lu Chen did not plan to go to Jupiter during this trial flight.

This time I plan to go directly to the asteroid belt and take some asteroids as a test.

However, only Hummingbird-class destroyers were tested this time. The test items included close-in defense guns, main guns, missile rain, etc.

The cargo spacecraft dragged an irregular asteroid with a maximum diameter of 10km directly from the asteroid belt to the blue star.

This asteroid was one that Lu Chen had already taken a fancy to.

From the outside, it looks like a rough sledgehammer,

Zero has roughly known the composition of this asteroid through detection.

The total mass of this asteroid is about 350 billion tons. The most abundant elements are iron and nickel, but there are also a large amount of rhodium, magnesium and other metals.

In addition, a large amount of ice cubes were found on it, and it is initially estimated that nearly 10 million tons of water can be extracted.

And because of its shape, it was named "Iron Hammer"

This asteroid is only about one-fifth smaller than the previous asteroid that hit the Blue Star.

Thinking of this, Lu Chen felt that the world was changing so fast.

Two years ago, let alone asteroids five times larger than this one, even the asteroid chosen now would make Blue Star extremely nervous once it flew to Blue Star.

But now, an asteroid of this size can be rubbed at will.

However, without this disaster, there would not have been so much technological development.

Without further ado, he turned around and looked towards the Mars base.

At this time, the two spacecrafts had reached their respective cruising speeds after an hour of acceleration.

Soon, the two spacecrafts reached the asteroid belt.

At this time, at the edge of the asteroid belt, the asteroid-class spacecraft began to move away from the destroyer and headed for the scheduled asteroid Hammer.

The destroyer continues to go to the predetermined area for testing,

The asteroid-class spacecraft continued to sail towards its target, encountering many asteroids of different sizes along the way.

However, they were all dodged by the shipboard artificial intelligence operating the spacecraft.

As for those who really can't dodge, just use the close-in defense cannon to smash them directly.

After all, although it is said to be a close-range defense artillery piece, its attack range is tens of thousands of kilometers.

After approaching the target, the artificial intelligence controls the spacecraft and the asteroid to be in a relatively stationary state.

Then the rear hatch opened, and the robot began to transport some equipment to the asteroid.

Because the flight speed of this asteroid is 300km/s, which is much slower than the speed of the spacecraft.

So this time the spacecraft carries eight fourth-generation ion engines.

Install these engines in the eight directions of the asteroid,

Then he took several ten-meter-thick steel cables and fixed them on the spacecraft and asteroid.

Lu Chen was also watching the construction on the moon. After seeing that everything was completed, he ordered the spacecraft to find a good angle and started to simultaneously start the ion engines on the spacecraft and the asteroid to push the asteroid away from the asteroid belt.

After receiving the order, the spacecraft began to adjust its angle and accelerate.

At the same time, the ion engine on the asteroid also began to start under the control of artificial intelligence. Through multi-angle collaboration, it exerted forces in different directions on the asteroid.

From the camera on Lu Chen's side, it can be clearly seen that the "Iron Hammer" asteroid began to change direction, deviated from its original orbit, and flew out of the asteroid belt under the drag of the spacecraft.

However, in this process, although the asteroids in this asteroid belt are very far away from each other,

But there will still be some small asteroids flying by,

In order to ensure that the asteroid can escape normally, the close-in defense cannon on the spacecraft began to eliminate these threats.

As time went by, the spacecraft dragged the asteroid and adjusted its angle, and began to gradually accelerate towards the moon base.

And by this time, the asteroid capture operation will basically be completed.

After this success, the next plan is to combine multiple spacecraft to pull "Ceres" out of the asteroid belt and send it to the moon.

Ceres also has a large amount of water resources, both liquid water and ice.

However, scientists previously speculated that Ceres still has a core that has not yet cooled down. I don’t know if this is true. Maybe we will know in a few months!

"Zero, continue to build four large space smelting factories near Blue Star and close to the sun.

At the current speed of spacecraft, 50 asteroid-class spacecraft are rolled off the production line every three months. A mere space factory is not enough. We need to increase production capacity.

Then, after the third batch of spacecraft comes off the assembly line, they will carry a batch of materials and equipment and go to Pluto to establish a defense circle on the outer reaches of the solar system! "

Seeing the success of this spacecraft test, Lu Chen also started the solar system defense circle plan that he had already prepared, preparing to build a large number of roadbed defense weapons on the eight planets and Pluto.

This is also a plan that has been decided with Long Guo.

Weapons are provided by Longguo, and installation and operating personnel are provided by Longguo.

Since Lu Chen's spaceship was built very quickly, the transportation task was handed over to Lu Chen.

Lu Chen had no objection to such an allocation. After all, he could be said to have purely mechanized production and had never hired any workers.

And as a private company registered in the Dragon Kingdom, it does not have the right to recruit troops.

So I own some robots, which are good at execution, but when it comes to tactical thinking, they are mentally retarded.

After looking at the cargo spacecraft, Lu Chen looked at the destroyer again.

Although in general, the tonnage of a destroyer is only 30,000 tons, in the interstellar era, large tonnage is not enough. It also depends on armor, attack, speed, flexibility, etc.

Not to mention anything else, this destroyer can destroy an asteroid-class spacecraft with one shot of its main gun.

In terms of the destroyer's energy, it can fire at least a thousand rounds of ion main cannon.

The hydrogen fuel cell stack used inside it is composed of 10 large hydrogen fuel cells, which can support the destroyer to patrol within a light-year range.

At this time, the destroyer was already approaching the target area.

In this area, the number of asteroids is slightly denser, and the diameter of the entire area is one astronomical unit in length, which is 150 million kilometers.

After arriving in this area, the main gun on the destroyer began to charge, and then aimed at an asteroid in front.

After entering the firing range, the main gun fires immediately.

In the dim space, two green charged ion clusters were quickly shot from the destroyer's main gun port and flew to the asteroid.

In the monitoring module of the hydrogen fuel cell, which is specialized in the use of main guns, the usable power is reduced by two thousandths.

Because the main gun is a two-unit main gun, one shot is two ion cannonballs.

So the actual number of rounds is 500 rounds for each main gun. There are six main guns in total, which is six batteries.

In addition to the energy supplied to the spacecraft for flight, there are a total of 16 hydrogen fuel cells.

In the original design, Lu Chen planned to use a nuclear power plant for energy supply, but because the nuclear power plant took up too much space, he replaced it with a hydrogen fuel cell.

At this time, after the ion cannonball flew, it hit the asteroid on the flight path.

The asteroid was immediately shattered, and there were signs of melting on the edges of each fragment, and some of the sandy surfaces had been burned into glass, which began to reflect sunlight under the sunlight in the distance.

This shot directly caused the asteroid's magnitude to rise a little.

Seeing this power, Lu Chen was also very satisfied. If nothing else, just this one shot, it is estimated that no one in that fleet could resist it, unless they developed an ion shield.

However, Lu Chen also took this situation into consideration and reserved a replacement port for the laser cannon at the beginning of the design.

Moreover, the ion shield consumes a lot of energy and cannot be turned on all the time.

After experimenting with the power of the main gun, next came the medium-range missiles.

As the launch silos on both sides opened, the Dongfeng 41 modified inside was ejected directly, and then the tail ion engine started and began to fly to the target.

This time it’s the same asteroid as before. Although it has been blown to pieces, there are still many large fragments.

After a period of flight, the missile successfully hit these fragmented asteroids,

I saw a small sun appearing in the distance, and these nuclear bombs with an yield of 10 million tons exploded.

Lu Chen had already put on the prepared sunglasses. After all, it was a high-definition camera and the light was still very strong.

Due to the emptiness of space, the shock wave quickly reached the destroyer.

Since the engine was not turned on, it was just pushed back a little by the shock wave.

However, because the tonnage is large, it does not have much impact.

This force test is basically over. After all, there are not many ship-borne weapons.

As for the speed and flexibility test, the speed can already reach 2% of the speed of light, which is enough for the time being.

As for flexibility, it can't be measured in a short while. It can't be like drifting in space!

The final armor can really only defend against some conventional weapons on Blue Star. It cannot defend against nuclear bombs, ion cannons, and laser cannons.

However, there is no other way around this situation. Lu Chen also really wants energy shields or energy armors like those in science fiction movies.

Unfortunately, due to technological limitations, this cannot be achieved for the time being.

After the basic test was completed, Lu Chen ordered the destroyer to return and then stand by at the Mars base.

Then I checked the situation of the asteroid-class spacecraft and found that there were still seven days to arrive, so I went to do other things first.

I will update one chapter first, and the next chapter will be updated in the evening.
