Chapter 104

"How?"

"This is the kinetic energy weapon of aliens! Even if it is a super hydrogen bomb, there is no way to take it!"

"Even if the asteroid impactor is built, it can only slightly change the orbit of perishable star. It is almost impossible to capture it!" experts said.

"It's still possible." Du Xingyu took it seriously. "The asteroid impactor still needs to be built. Strictly speaking, the asteroid impactor also belongs to space kinetic energy weapons, which is the same as the death star."

"However, we can't create mass kinetic energy weapons such as death star, so we need to build multiple asteroid impactors to force Death Star to slow down and change its direction."

"Now that we have mastered the technology of controlled nuclear fusion, it is possible. But how do we capture the death star?" someone asked.

"This is where the scheme needs to be modified." Du Xingyu simulated hundreds of times with a science and technology simulator before the meeting, and came up with a feasible scheme.

"Our original plan was to use an asteroid impactor to force the death star to change its direction near the orbit of Mars. Now we want to extend the defense line to the orbit of Jupiter!"

"Using Jupiter's gravity to control the death star?" astronomers soon guessed his idea.

Jupiter is the largest and fastest rotating gas giant planet in the solar system. It is the fifth farthest planet from the sun, accounting for 70% of the mass of planets in the solar system!

And Jupiter's gravity is 2.5 times that of the earth. Many asteroids will be pulled by Jupiter's gravity and swallowed up before flying to the earth! During the formation of the earth, Jupiter blocked meteorites, comets and asteroids for the earth many times.

"That's right," said Du Xingyu. "It's really difficult to capture the Death Star by our technology alone. But we can change the orbit of the death star through the asteroid impactor, so that when it flies into the orbit of Jupiter, it can use Jupiter's gravity to capture it and become a satellite of Jupiter."

"In this way, our spaceships or space warships can go to study the death star and solve the Death Star crisis."

"The premise of all this is that the kinetic energy weapon of Death Star is indeed dormant, and alien civilization will not interfere with our actions," someone said.

"This is also our temptation." Du Xingyu also thought of this problem. "If our plan can proceed smoothly, it means that our enemy is not willing or able to project more powerful armed forces to the earth."

"Even if we can't capture the death star, we can also use the asteroid impactor to crash the Death Star into Jupiter! Destroy it directly! This can minimize the risk of hitting the earth!"

"I agree!"

"I also support it!"

"At present, this plan is really better than the previous one. If it goes well, we can get more information about potential enemies - only, the average distance between Jupiter and the earth is 780 million kilometers, that is to say, our asteroid impactor should be launched 780 million kilometers away and hit accurately!"

"Not only the kinetic energy needs to be met, but also at least four and a half years ahead of the previous plan. Is there time?" someone worried.

"If all parties cooperate fully, there is still a chance." Du Xingyu has calculated for a long time. He said: "ideally, we still have eight years to complete the manufacture of space warships and asteroid impactors."

After the meeting, the human Guardian alliance readjusted its crisis response plan. To the outside world, they did not announce the discovery of the products of alien civilization on the planet of death.

All parties agreed that since all mankind has united and has just achieved some results, there is no need to create panic now.

Also because of this, the cooperation between all parties is closer.

……

Du Xingyu has more to do. The plan of space defense and solar system satellite network has been further promoted. New exploration satellites fly to further areas of the solar system to look for traces of the enemy.

He himself is the main designer of space warships and asteroid impactors.

"The asteroid impactor is a space kinetic energy weapon, and its structure is not complex. The main difficulty lies in the high-power nuclear fusion propeller." Du Xingyu thought carefully, "that is to say, as long as the design of ultra-high-power nuclear fusion propeller can be completed, the asteroid impactor can be manufactured."

"As a kinetic energy weapon, its mass must be large. The ideal state is to make it with a high-quality metal creation. Prepare the shell first."

Du Xingyu first arranged the asteroid impactor project. He planned to use space elevators and spacecraft to transport materials to the moon.

In the new space weapons factory on the moon, the "main body" of the asteroid impactor is produced, a huge, solid large metal object.

In terms of thrusters, Du Xingyu plans to study together with the thrusters of space warships.

Since it is a space warship, its kinetic energy must be much stronger than the existing spacecraft, so it is also necessary to design a new nuclear fusion propeller.

On the science and technology simulator, Du Xingyu opened a new branch of science and technology - space warship.

"10 million energy points have been consumed to open the branch," prompted the technology simulator.

Under the branch, Du Xingyu can see many dim images. All kinds of space warships are also divided into various levels.

Planetary class: a space warship with the ability to strike and fly in a single star system.

Star class: a space warship with the ability to strike and fly in one or more star systems.

Star River class: a space warship with the ability to strike and fly in a river system galaxy.

……

Each class of space warships is divided into many types.

The explanation of the science and technology simulator is: "there is no real standard classification of space warships, which can only be roughly estimated. Now the nuclear fusion powered warships you can develop belong to planetary warships. Even if they are the same planetary warships, there is a big gap because of the differences in power, weapons and other scientific and technological equipment."

Du Xingyu points to the star warship and continues to watch.

There are also numerous branches of warships here, such as star cruisers, planetary battleships, planetary supply ships, planetary destroyers, planetary work ships, planetary supply ships, planetary landing ships... And the top presence of planetary warships - Planetary Star Destroyers!

The so-called Star Destroyer is the combat effectiveness of a warship, which can destroy a planet!

Of course, mankind has no ability to manufacture such super warships.

Du Xingyu's heart is full of longing. Only with such a space fleet can mankind embark on the first step of star civilization!

The previous rockets, spaceships, space stations and space elevators were all small things. In the final analysis, they were still playing near the earth.

"The first research and development goal is to choose the first generation Star Cruiser!" Du Xingyu quickly established the goal.

The planetary cruise ship, with sufficient power, will have the ability to enter the atmosphere freely, which is very suitable for construction on earth.

Secondly, although its firepower is not as high as that of battleships, it is faster and more suitable for going deeper into the solar system to find the earth and deal with the death star.

The material carrying capacity of the cruise ship is also excellent enough.

It is also a space warship with the most standardized combat effectiveness among planetary space warships. Du Xingyu wants to make more powerful warships. However, mankind does not have that industrial level and scientific and technological strength, so we can only start with standard warships.

Science and technology simulator: "does it consume 10 million energy points to start the simulation of Star Cruise Ships?"

Du Xingyu: "sure!"

Technology simulator: "Star Cruise Ship simulation has been started!"

From Du Xingyu's perspective, there are various planetary cruise ship models and user-defined model groups.

There are three main models recommended by science and technology simulator.

The first is a torpedo shaped cruise ship, which is closer to a rocket with its propeller at the tail. This is more convenient to manufacture and easier to get in and out of the atmosphere.

The second is a flat cruise ship with a surface area close to isosceles triangle. It looks like a sharp arrow, and the overall design has a sense of science and technology.

The third is the UFO shape, just like the UFO in science fiction movies.

The three shapes have their own advantages and disadvantages. Du Xingyu can also choose other simulation directions.

Since this is the first research and development, not only he, but also human manufacturing experience is limited, Du Xingyu chose the model II, arrow shaped space warship recommended by the simulator.

"The estimated length of the warship is 788 meters. The maximum width of the warship is 345 meters. The total mass is more than 30000 tons..." Du Xingyu began to plan the overall model.

From the appearance, the volume of the first generation of star cruise ship is three times larger than that of the largest Ford class aircraft carrier in the United States, but its total mass is much smaller.

In order to consider the problem of atmospheric flight, the planetary cruise ship should fully adopt brand-new carbon fiber and nano materials to reduce the mass of the ship body, so that the propeller can push it out of the atmosphere and break away from the planetary gravity.

"There are many problems in the design of the ship body. What is more difficult is the design of nuclear fusion thrusters of space warships and space weapons..." Du Xingyu found that even if he can get a lot of information and help by using the technology simulator, this thing can not be developed by him in a few months.

The most suitable way is to cooperate with the world's top experts, let them give advice, use their own technology simulator to overcome difficulties and eliminate inappropriate solutions.

The world's top military weapon experts, engineers and the most powerful aircraft carrier designers of several major countries were called to China to start a new project - "research and development of the" Silver Wing "planetary space cruise ship.

"Materials and structure are the first step for the team to consider." Du Xingyu said at the meeting of core members of the project team. "As for space weapons and nuclear fusion thrusters, I personally participate! I hope you can make every effort to come up with a plan in the shortest time!"

"Hmm!" everyone is very careful. They know that this project will determine the fate of mankind. Whether it will become an interstellar civilization or be destroyed by the enemy on earth, space warships determine everything!
