In the context of the times, there is never a shortage of wonderful stories. The love-hate relationship between individual human beings has constructed the diversity of human social development.

Five hundred meters away, Ren Di looked back at the eyes of a pair of young men and women behind him, and smiled lightly. He said softly, "Time is running out in the tower. The need to do is done. ”

The future of the tower is not over yet, but what Ren Di should do is done. The tower will go down on its own. In the future, the tower may perish because it will fall into the pit of history again, but it will not perish in the present era.

The cosmic tragedy in Ren Di's eyes is far more than just a civilization in the Iron Tower, every civilization is like a small fish stranded on the beach, bouncing, and Ren Di is now only throwing one of them back into the sea.

The camera switches, in the vast universe, space battleships are floating. These battleships look as big as 10,000-ton destroyers on the sea, but in fact they weigh less than two thousand tons. Massive amounts of steel foam and Kevlar plastic, as well as non-Newtonian liquid armor (early 21st century technology).

Such armor in space is not false, because there is no oxygen, so it will not ignite in space, and this space battleship is among several threats to be avoided in space. There are no cases where the armor is ignited.

The first space threat is an electromagnetic projectile with an initial velocity of seven kilometers per second and a mass of six kilograms per shell. The warships of both sides will shoot at each other at a range of 1,200 to 500 kilometers, and the accuracy of shooting at 1,000 kilometers is the same as that of battleships in the dreadnought era.

Although the accuracy of long-range shooting is not high, it is the most effective way to attack, and if a six-kilogram shell hits a battleship, the battleship must only use its own armor to withstand the damage, and there is no other way.

The outermost layer of ceramic radiation-resistant and heat-resistant armor will be directly penetrated, and the foam metal cannot block the penetration of kinetic energy projectiles, and the main force against electromagnetic shells is the internal Kevlar fiber, a plastic product, which is used in body armor in the 21st century. This layer of plastic armor is lightweight, insulated, and insulated, and when it is hit by kinetic energy, it will break a lot and reduce kinetic energy with its own destruction.

However, there will also be a layer of armor inside, and this layer of armor is the most popular liquid armor of the 21st century on Earth, which is scientifically terminated as a non-Newtonian.

When a large amount of molten flour is introduced into a tank of water, a snot-like thing will form, and if you press it slowly, your hand will easily press it. But if you raise your hand and slap it, sorry, you will feel like your palm is being pumped back. There will be only slight flutter on the liquid surface. It's like the jelly that flutters when it's flicked.

The non-Newtonian body of a large swimming pool can support a human to run on it, as if stepping on a large pool of snot. This is the distance of liquid armor, when the force is slowly applied, it will deform, but if the force is suddenly applied, the deformation will not change instantaneously, and the incompressibility of the liquid will be revealed. The technology of the 21st century wants to apply this to body armor, so that bullets can hit it, so that the incompressibility of liquid fibers can resist, and the only technical difficulty is to keep the fibers light enough to be worn on clothes, and it can also be effectively bulletproof.

And in space, the gigantic warships are able to apply this technology with ease. This is a direct contest between armor and ammunition. When the warhead hits the battleship, the operator inside the battleship will feel the whole battleship tremble violently, but the battleship will not be penetrated.

The second threat faced by space battleships is laser weapons, which must be hit accurately, and the outermost layer of ICBM ablation-resistant materials of the battleship will resist the laser, not that the laser cannot burn this layer of material, but will directly evaporate with the energy of the laser.

In space battles, each laser beam is extremely short interval, if you want to burn the opponent's warship for a long time, the long beam in space will become the most distinctive pointing symbol, and will become the target of other warships. So it's all like a laser gun, emitting beams of lasers. In space, warships are constantly moving in relative motion, which means that it is impossible for each laser to hit the same position.

The outermost layer of heat-resistant tile-like armor is not thick, and returning to orbital port maintenance and affixing new tiles is another good warship. Laser cannons are mainly used in space to defend against unmanned small aircraft.

The third threat is the magnetic pulse. And this layer of defense is given to thick foam armor. The metal layer effectively blocks electromagnetic waves. The metal layer can shield electromagnetic waves, but when the electromagnetic waves are shielded by the metal layer, an electric current is generated on the metal layer. When a strong current is attenuated, secondary electromagnetic waves are generated. So the metal shell of the space battleship is not a layer.

A direct impact of the magnetic pulse on the Foam Armor will bring electricity to the Foam Armor, but this part of the energy will be consumed on top of the Foam Armor and will not affect the internal computing equipment. This is the role of metal foam in space warfare,

The space warships of this era were only 2,000 tons and ranged in length from 150 to 70 meters. It's not that the sixth-level civilization doesn't want to build a larger space battleship, but it's stuck in the thrust, and the space battleship uses electric propulsion when cruising in space, and chemical propulsion in wartime. The power of the fission reactor could not keep up, allowing the mass of the battleship to reach its limit at two thousand tons. No matter how big it is, it will affect the cruising performance and maneuverability of the warship in space.

And the more advanced space warfare technology will have to wait until the more advanced power system, but that is the technical condition of the seventh-level civilization. Before the breakthrough of controlled nuclear fusion technology, the quality of all warships must follow the law.

Now in space, the warships of the sixth-level civilization are floating in space, and the appearance of the battleship is like a stealth fighter without wings. It's not J-20, J-20 also has to compound aerodynamic conditions, and J-20 has to maintain a streamlined curve replacement outside the diamond-shaped nose. If you compare the style of the fighter to the F-117 Nighthawk stealth fighter, the style is similar.

And it is more extreme than the Nightingale fighter, the whole body is water chestnut, the entire shape of the battleship is water chestnut, the raised turret on it is water chestnut, and the chemical afterburner jets on the left and right sides are like the wings of a juvenile quail. In order to avoid radar irradiation, the diffraction phenomenon of electromagnetic waves (light will be reflected when it hits the oblique plane of the object, and the oblique surface can be used as a mirror. Play to the extreme. The style of the space battleship is this style of pyramid to the sky.

The style of the pyramid in the sky is the universal nature of a space battleship. Just like in the era of dreadnoughts, all countries on the earth used the main guns to be arranged along the center line and unified the caliber of the main guns. This is the general trait that dreadnoughts must follow.

However, how many chemical thrust devices are there for each battleship's turret arrangement? The details of each space battleship are still different. After all, it is necessary to stuff various chemical fuel tanks, personnel living compartments, ammunition compartments, and nuclear reaction chambers into the limited internal space of the angular style warship, and each warship production plant has its own unique ship-building data.

If you are an expert in the military and martial arts of the Yager civilization, you can see that the fleet cluster that is now traveling in space is mainly produced by twelve forces. Among them are some pirate ships of unique style, which are loaded with various radars as well as enhanced cruising and cut down armor.

This is a mixed fleet, for a sixth-level civilization, a space battleship is not a rifle, it is not bearable, and the army can be replaced. In the space warships made by the sixth-level civilization, every piece of material is sent by chemical rockets on the ground, and there is no controlled nuclear fusion to greatly reduce the cost of materials. One can imagine how expensive these space battleships are.

Every space battleship with a tonnage of more than a thousand tons is a hard asset in the sixth rank. This is the capital ship. In the Yager civilization, the number of capital ships registered with a tonnage mass of more than two thousand tons is about thirty thousand.

On average, one or two planets support a thousand-ton warship in the sky. The limit of the Jager civilization is to have 200,000 warships. It was the era of chaos 8,000 years ago, with the rise of warlords in space and pirates entrenched in various systems. The era of war, which lasted for three hundred years, was the era with the largest number of space warships.

And now Yager is a republic, in fact, it is also the warlords who rule, the big warlords and the small warlords form an alliance to maintain the stability of the world, but in fact, the government that chooses a career is the same as the court in the late Eastern Han Dynasty, and the warlords rarely bird him. The warlords who controlled the government also planned to blackmail the Son of Heaven to order the princes.

Of course, the authority of the government is not even as good as Emperor Han Xian, and when Emperor Han Xian was there, the princes did not dare to point at Emperor Han Xian's nose and scold. And now, when the warlords are not satisfied, they openly contradict the government that chooses jobs. Careers are essentially the nature of the United Nations.

Whoever has more warships has the right to speak, although in this era, the total number of warships of various forces is small, but each warlord has not a lot of materials hoarded in space orbit. Because it costs too much money to produce space warships to maintain them from wear and tear, but if necessary, the era of the abundance of warships 8,000 years ago will come again.

At present, the number of capital ships of the Grand Fleet of more than 2,000 tons sailing in space is 283, and the number of warships of the rest of the ships of more than 1,000 tons is 1,526. This is a powerful fleet cluster in the Jager civilization. On a giant flagship of 3,824 tons in the fleet cluster, Chen Ru was sitting on the control platform inside the warship, and the hemispherical screen showed the vast space.

The metal position where Chen Ru was sitting was suspended on this platform, and below the platform, many soldiers in white space suits were busy, contacting the situation of the various warships in the fleet.

The letters Z, X, V, W, T (not the Latin alphabet) are followed by numbers that mark the symbols of the fleets, and warships are marked on a hemispherical screen that simulates a view of outer space. A large fleet in full view, so that those sitting in the floating seats know the positions of their various warships in space.

This is the flagship, Chen Ru is a warlord, a flagship of 3,800 tons, and the tonnage far exceeds that of other warships. And it has the performance of any warship. Because Chen Ru is an energy releaser.
