"A reconnaissance spaceship discovered an unknown space fleet invasion during a routine patrol, and sent back a warning before it was destroyed, and the first mixed fleet immediately set off to the area where the incident occurred, searching for and annihilating the invading enemy!"

Wang Dao gave a brief introduction to the intelligence and gave the First Fleet an operational order.

The defense command center located on the moon was already full of people, including the three elders and senior generals of the army, all of whom were watching the exercise in real time.

Six months have passed since the war began, and two brand-new 100-million-ton universes have been built.

In the war of the space age, if there is no absolute technological superiority, the speed of resource exploitation and the production efficiency of weapons and equipment are the most important factors for decisive victory.

The exercise was conducted with two 100-million-ton warships as the core, and the first and second fleets, which had just been formed.

Under the circumstance that they cannot take part in actual combat, the exercise is undoubtedly the best means to verify combat methods and explore ways to use equipment.

Although this effect can also be achieved by combining wargame deduction on the computer with realistic training, the sense of participation of personnel is not as strong as that of the exercise, and the effect is not so meaningful.

Woowoo woo –

The poignant and piercing sound of battle sirens sounded in all the spacecraft compartments of the First Fleet.

"The fleet is in a state of war, all personnel are immediately at their posts, the ship's engines are ignited, and they are ready to go!"

Fleet Commander Liu Yuejun quickly gave the order to prepare.

The spaceships docked in the spaceport started their engines one after another and slowly began to move.

With a full load of 120 million tons, a length of 12,000 kilometers and a thickness of 2,000 meters, the flagship looks like a big cigar.

The main combat force is a thousand super-powered laser cannons and a hundred electromagnetic railguns scattered all over it, and the number of other low-power weapons combined exceeds 100,000.

The main protection of the spacecraft, in addition to the high-strength alloy armor with an average thickness of thirty meters on the outside, is also a force field shield.

Ten kilometers from the outside of the ship's armor, all of them are equipped with force field shields, which can counteract laser strikes, deflect, or control kinetic weapons.

The flagship is large and not slow, and after a day of full power acceleration, the top speed can reach one-tenth of the speed of light, which is 30,000 kilometers per second.

In addition to the flagship, there are 100 other main ships and 1,000 auxiliary ships, with a total weight of more than 3 billion tons.

The main spacecraft are all of the 10 million ton level, mainly fireships and defense ships, and most of the auxiliary spaceships are about 1 million tons, including reconnaissance, communication, supply, medical, rescue, storage and other functional spaceships.

Most of these ships are only equipped with basic self-defense weapons, and the combat effectiveness of the battlefield is not strong, but the multiplier of the combat effectiveness of the main fireship.

Especially in long-distance interstellar voyages, in addition to the materials carried by the spacecraft itself, other materials must be replenished by supply ships.

For example, the food supply ship is a complete agricultural production base, which is mainly engaged in the cultivation and production of animals and plants, and provides sufficient food for other ships.

Mining vessels are responsible for collecting all available resources found during the flight, including but not limited to various metals and water.

"Report to the Commander, all the ships of the First Fleet have left port, please instruct." The voice in the intercom woke Liu Yuejun up from his excitement.

As if in a dream, in less than three years, he had changed from the commander of the Eastern Theater in China to the commander of the space fleet rampaging in the solar system.

Without the slightest pause, Liu Yuejun began to give orders: "Take the reconnaissance spacecraft's missing coordinates as the center, and carry out a laser strike on the surrounding fifty light sky area!"

With the flagship as the core, all ships accelerate to maximum speed.

The fleet's reconnaissance ship went out to guide the fleet to fly, investigate more situations, and prepare for the follow-up battle. ”

"Yes!"

After the communicator answered, the whole fleet got busy in an orderly manner.

The reconnaissance spacecraft crash area is nearly 80 billion kilometers away from the First Fleet's home port, and the entire fleet needs to sail at full speed for more than a month to reach the combat area.

If the two fleets sail opposite each other, they can engage in battle after half a month, and either side starts to go around in circles, and the time does not know how long it will take, and maybe it will not be found in a lifetime, but it is also possible.

The universe is three-dimensional, and as long as you don't want to stay where you are, you can escape from any direction.

If you get the direction wrong, even a millimeter of deviation will be lost by a thousand miles after the distance is magnified.

Countless lasers were launched from each ship, forming an impenetrable net, enveloping the target area.

Subsequently, the 500 reconnaissance ships belonging to the First Fleet also began to accelerate first, speeding away closely behind the laser.

The reconnaissance spacecraft is like a flat, diamond-shaped shuttle, with a total weight of no more than 100,000 tons, but its speed can reach one-half of the speed of light.

The First Fleet's reconnaissance ships, a total of 500, were all dispatched, scattered, and searched towards the area of the accident.

The entire fleet also formed a battle formation and began to accelerate, sailing at breakneck speed.

"Why laser strikes in the first place? It's meaningless and reveals, so explain it to us. ”

No. 1, who was sitting in the general dispatch room, asked Wang Dao, who was personally the chief referee.

Wang Dao looked away from the fleet image, looked back at No. 1, and replied with a smile: "This is a simple fire reconnaissance to see if you can beat the enemy out."

This is the same as the previous wars on earth, shelling suspicious places, or strafing with machine guns, as long as the enemy does not deal with it properly, it is easy to show its feet. ”

Number Four listened and interjected: "Listening to you say this, it feels like the war hasn't changed much!" ”

"Everything changes!" Wang Dao summed up briefly and continued: "It's just that it has changed from a flat era on the earth to a three-dimensional battlefield in the cosmic era.

The law will not change, and there will be no major change in the thinking of war.

Like Sun Tzu's Art of War, it will never become obsolete, and the phrase 'a soldier who surrenders without a fight' in it can be regarded as the truth of war.

No matter who the opponent is, only if we can have the strength to crush it, can we force the opponent to surrender. ”

"Well, that's exactly what I said." Number One nodded in agreement.

Wang Dao began to illiteracy the elders again: "The distance between celestial bodies in the universe is very far, far away, if we use meters and kilometers as the unit of measurement that we use in our daily life, then the number of measuring the distance of celestial bodies is often more than a dozen or dozens of digits, which is very inconvenient.

So we adopted a unit of measurement created by astronomers – the light year, which is the distance that light travels in a year in a vacuum.

Distance is equal to speed multiplied by time, and the speed of light multiplied by seconds, minutes, hours, days, months, and years can represent the specific length. ”

Light seconds are the basis, representing 300,000 kilometers, 60 seconds a minute, and 60 minutes an hour.

Twenty-four hours a day, thirty days a month, three hundred and sixty-five days a year.

Depending on the actual needs, precise calculations can be made, calculated at the actual speed of light of 299,792,458 meters per second.
