All the experimental data stored in the computer was destroyed, causing a major blow to the curvature-driven research.

This means that if you want to continue to study the curvature engine, you need to do the experiments that have been done in the past three years again.

Re-experimenting and having experience will be faster than starting from scratch, but that will take at least more than a year.

However, what humans lack the most now is time.

Yang Yuping was once in despair and almost collapsed.

Today is a military exercise for the human space fleet, and Fang Yuan almost brought the old professor over.

The main purpose is to let the elderly relax.

"The experimental data is gone, and we can still do the experiment again. There is nothing to worry about, just start over. Today is a space fleet military exercise. In fact, we are not weak now. Even if the Purifier civilization comes, we will fight first."

Fang Yuan stood on the spaceport on Earth and pointed at the battleship anchored on the apron in front.

Looking at the battleships shining with metallic luster and the endless starry sky ahead, Yang Yuping felt a little cheerful.

Human beings are indeed much stronger than three years ago. They have built a spaceport and a lunar base, and have a fleet of 1,000 space warships.

Among them, the largest flagship Blue Star space carrier, with a total length of 1.2 kilometers and a volume of 30 times that of the largest aircraft carrier in the ocean era. It is an absolute giant space ship.

The crew of the entire ship requires 18,000 people to operate in full capacity, not including combatants.

The Blue Star also houses 500 carrier-based combat ships and 1,000 space unmanned attack aircraft.

In addition to the Blue Star.

There are also 5 Arctic Ocean-class space battleships in the human space fleet.

36 space cruisers, 125 space destroyers, and 800 space combat ships.

Several Shenzhou-class ships belong to the category of destroyers, but there was no further mass production in the future. This model.

Because the Shenzhou has undergone too many magic modifications through military scientific research classes, there is no possibility of mass production of materials using the hull with the number of strong nuclear force materials.

Therefore, the Shenzhou and Chixian have become military scientific research space destroyers.

Many advanced technologies will be placed on the Shenzhou for testing. After the technology is mature, they will be placed on other models of warships.

Today, the human space fleet conducts military exercises with the goal of fighting the coming Purger spacecraft.

The space fleet flew out of the spaceport neatly, covering the sky and the sun.

The light of the engine illuminates the entire sky.

The military exercises were played on TV stations around the world in real time, and countless people were filled with tears for this.

If it were ten years ago, who would have thought that one day humans would have such a magnificent space fleet?

All mankind is hotly discussing this military exercise.

However, the news about the arrival of the Purgator civilization has been strictly confidential.

Therefore, ordinary people do not know what is behind this military exercise.

Some people praise it, and naturally some people belittle it, and the content of the discussion is strange.

"There are battleships like battleships appearing in the space fleet again. Is it a regression in history?"

"The battleships re-emerge onto the stage of history is inevitable to move to space."

Those who have a little understanding of space warships began to explain to their friends: "Space is a vacuum, and the disappearance of air resistance is destined to the return of kinetic energy weapons.

"In the ocean era, why did battleships dominate the ocean? Because of the resistance to beating, huge armor can withstand shell bombardment.

"The emergence of missiles has allowed artillery to fall off the altar, because missiles can completely sink targets outside the range of artillery, resulting in the armor of battleships being useless.

"Space is different. Air resistance has killed the kinetic energy weapon such as artillery, but space has brought kinetic energy weapons back to the stage of history.

"On the contrary, in space, missiles have some disadvantages. The missile launches at a low initial speed, are easily intercepted, and require propulsion engines, which consume more energy and resources.

"In terms of cost-effectiveness, missiles cannot compare with kinetic cannons.

"Therefore, the return of kinetic energy cannons has become inevitable, and the super thick armor that defends kinetic energy cannons also returns naturally.

"So, it's not surprising that the battleships will return to the stage of history.

"Since the Supreme Council has built space battleships, it must have done an analysis."

Questions about the types of space warships.

In the past few years, it has been discussed continuously and has done many model analysis.

As the technology of electromagnetic guns becomes more and more mature, the power of kinetic energy weapons is indeed becoming greater and greater, and the shells of kinetic energy weapons are indeed more economical than missiles.

For ordinary people, the current space fleet of human beings is indeed extremely spectacular.

However, in the eyes of those who truly understand the truth, they still feel worried.

Yang Yuping looked at this space fleet formed by countless technologies and felt emotion in his heart, but at the same time he could not let go of his worries.

"Can our fleet really beat the Purgator civilization?"

Actually, this question does not need to be answered at all.

Luohu's smuggling aircraft used antimatter bombs, and the weapon power of the Purifier spacecraft cannot be lower than that of the antimatter bombs.

In the face of antimatter bombs, strong nuclear armor is difficult to withstand. Even the battleship with the thickest armor in the space fleet is not optimistic in the face of antimatter bombs.

Fortunately, humans also have antimatter bombs.

Therefore, the human space fleet cannot withstand the attack of the Purifier spacecraft, but also has weapons to break through the Purifier spacecraft's defense.

So, this battle can still be fought, but it will definitely not be easy.

"The Academy of Military Sciences said when did the Purifier spacecraft arrive in the solar system?" Yang Yuping turned and asked.

"After analyzing, it is expected to arrive within three months." Fang Yuan replied.

Three months, it’s not too short.

But when facing a civilization-level crisis, there is actually no major move to change the situation.

"Have the Fire Number set out?" Yang Yuping asked again.

"I've set out, I've set out last night and headed towards the Big Arctic Star." Fang Yuan replied.

The Fire, as the name suggests, is the spacecraft carrying the Fire of human civilization.

In fact, the Tinder Plan has been going on in secret.

Standing at the height of civilization, continuing the spark of civilization is an issue that a civilized decision-making class must consider.

Torment is a long-distance spacecraft modified by an armed transport ship, which is loaded with 300,000 human fertilized eggs, as well as the history, culture, and technology of human civilization, and is looking for new habitable planets.

However, in three months, it cannot fly out of the solar system, so I can only hope that the fire number has not been cleaned will be discovered in civilization.

Those who stay on earth must fight the civilization of the Purgator to the end, but they must also make the worst plans.

The Tinder Plan is the worst plan.
