In the middle of January of the forty-second year of the galactic calendar.

The human fleet began to assemble on a large scale, and the fleet consisting of two satellite-class warships, twenty small planet-class warships, and three hundred meteorite-class warships slowly set sail, preparing to move forward to an area 150 astronomical units away from the flame gamma to meet the incoming enemy fleet.

The remaining reserve of one satellite-class battleship, eight small planet-class ships, and eighty-two meteorite-class battleships followed the airspace 10 astronomical units away from the main fleet in case of emergency.

This is the first time that humanity has been at war with aliens, and they know nothing about the enemy.

Of course, compared to the asymmetry in information, the bigger gap lies in the number of warships on both sides, the number of incoming enemy fleets is almost five times that of human warships, and the human race this time is more like Don Quixote charging towards the windmill.

Two hundred astronomical units away, the pirate leader Pruk was looking triumphantly at the data transmitted by the enemy fleet on the gravitational wave radar, and laughed: "There are less than four hundred warships, and there are still reserves left, is this group of earthlings funny!"

Kafra stood beside Pruk, and the two eight-character rat whiskers shook and smiled: "Your Excellency, great captain, maybe they are ready to fight to the death because they know that they will not be able to escape our pursuit!"

"Fight to the death?!"

Pruk sneered: "Since they are looking for death, then don't blame me for being ruthless! Order the fleet, reduce the curvature engine power, and start storing energy for the weapon station, when the time comes, our satellite-class battleships will attack the enemy satellite-class battleships first, and the small planetary-class battleships will cruise in the scene to hunt and kill the enemy's meteorite-class battleships!"

"Yes!"

Cazorla's mustache shook slightly, and she made a funny salute.

……

The Jiangcheng was hidden in the darkness, as if the war that was about to break out fifty astronomical units away in the distance had nothing to do with it.

In the command hall of the Jiangcheng, Eva was reporting to Chen Xin the latest situation on the front line.

"The hosts. The enemy's main fleet is still nearly 30 astronomical units away from our fleet, and at present, the enemy fleet has formed a battle formation and is rapidly approaching our side, and it is expected that the two sides will officially engage in battle in ten hours!"

Chen Xin nodded, looked at the two fleets that were approaching, and frowned slightly.

In general. The decisive battle of the fleets of civilizations below the third level will be carried out in the airspace of millions to tens of millions of kilometers.

The reason is very simple, the speed of light is 300,000 kilometers per second, and if the distance is too far, laser weapons and particle beam weapons will not work, and they can only rely on long-range gravity missiles, small and medium-sized warships, and interstellar fighters to attack the enemy's firepower network.

Therefore, it was only possible to close the distance between the fleets of the two sides.

But when the real decisive battle comes, it still relies on satellite-class warships and small planetary-class warships in the fleet.

Meteorite-class battleships are more like an assault force, with low defense and high attack, and can only take a bite at the enemy when they are not paying attention.

This kind of engagement is fundamentally different from missile warfare, air defense and anti-submarine warfare in modern naval warfare, but it is a bit like the era of artillery and giant ships during World War I, and it is more important to work in a team and cooperate. Starfighters and Meteorite-class warships serve as harassers.

Of course, this analogy is not entirely appropriate.

After all, at this time, no matter the number of warships used by both sides and the number of people participating in the battle, they are not comparable to the Earth era.

And in interstellar space, there are many times more factors to consider than on Earth.

However, these tactical issues were not something that Chen Xin needed to consider, and with the continuous transmission of intelligence from the stealth detectors secretly laid by Chen Xin along the way, Chen Xin also had a deeper understanding of this attack fleet.

The warships of this attack fleet are mainly the warships of the third-level and middle-level civilizations, and compared to the fleets tailored for humans by the Tianqin civilization, the two fleets are more than one grade behind each other in terms of vitality, mobility, and protection capabilities.

If you really had to make an analogy, it would be like comparing the battlecruisers of World War II with the battleships of the pre-dreadnought era. The enemy's only advantage is quantity, but in the face of absolute quality. This gap can be bridged.

Perhaps the only threat to the human fleet is the enemy's Pro-class ship.

The Pro-class spaceship is a civilian merchant ship of the fourth-level civilization, which is very favored by interstellar pirates, although this kind of merchant ship cannot even deal with the asteroid battleship of the fourth-level civilization, but when dealing with the third-level civilization, it is almost a devastating existence.

Especially after refitting, the weapon power and protection level of the Puluo-class merchant ships. It is a grade higher than the satellite-class warships of the third-level high-level civilization, and the only difference is in maneuverability.

Ships of civilizations below level 6 cannot fight when flying at a curvature, so the maneuverability of the battleship in the normal flight state has become an important indicator to measure the level of the battleship.

But the Pro-class merchant ships are too big, if a military warship is a strong lion. Then the Pro-class merchant ship is an elephant.

Therefore, the Pure-level spaceship is also to deal with a third-level civilization with low combat power.

Of course, those powerful third-level civilizations are not stupid, and they will directly buy small planetary-level warships from the fourth-level civilizations they are attached to to deal with the threat of pirates.

In this universe, it is not a great deal for a lower civilization to have a warship of a higher civilization.

However, the pirate leader, Mr. Pruk, obviously would not have imagined that the human fleet in front of him, which did not look amazing and had a limited number, was behind it was tailor-made by a fifth-level civilization.

Although the technology used by the third-level civilization is used, the actual combat effectiveness, except that it cannot fly faster than light, is not much different from those civilizations that have just been promoted to the fourth level.

……

Frank is a starfighter pilot aboard the USS Washington's small planetary spacecraft.

He is also a new human, a Chinese-American mixed-race, and his parents met and bonded after immigrating from Earth to the New Earth.

However, in Frank's brain, his concept of the state is not as important as that of his parents, and in his opinion, humanity has long since become one, and he will fight for humanity.

Frank's Wasp-class fighter jet, 28 meters long and 5 meters high, is armed with two 100 megawatt laser cannons, four electromagnetic railguns, and ten gravity bombs.

Both laser cannons and electromagnetic railguns are used against enemy meteorite-star warships and starfighters, and the real power is the gravity bomb.

The principle of this bomb is to instantly create an artificial gravity source through the gathering effect of the Higgs boson, and once it is close to the explosion, it can even tear a hole in a small planetary warship.

According to his flight school mentor, the most powerful gravity bomb would be a mass that compresses gravity to the extreme, with a gravitational force almost equal to that of a small black hole, which could even destroy a star if fired with a force field. (To be continued......)
