Chapter 255 Differences in Weapon Systems Regarding the equipment options of the ship category in the star domain market, Fan Ren then focused on the weapon turret category options. Among them, the forts are classified into five different categories. They are the electromagnetic railguns currently equipped on a large scale by humans, the missile turret system used by the battleships of the Hans civilization, and the projectile guns used by the dreadnought of the Fox Pirates. And the last type of laser weapon comes from the five major civilizations. Among them, the electromagnetic rails and laser weapons are powered by the integrated energy supply system inside the hull. The electromagnetic railgun is different from laser weapons. The electromagnetic railgun mainly consists of two parallel conductive rails and a movable armature located between the rails. When a strong current passes through these two parallel tracks, a strong circular magnetic field is generated around the tracks, and the direction of this magnetic field is perpendicular to the direction of the current and the plane of the track. At this time, the armature will move in the set direction due to the existence of the magnetic field.
The initial muzzle velocity of the projectile is determined by the above-mentioned reasons, such as the magnetic field strength caused by the current intensity and the length of the track. In short, the stronger the current, the longer the track, and the faster the projectile will leave the muzzle. Laser weapons are different. As a product of the fifth-level civilization with the highest technological level in the current Galactic Alliance, this laser weapon must use crystal media provided by the five major civilizations in order to exert its powerful lethal effect. This special medium can excite the atoms in the medium and make them jump from low energy levels to high energy levels after electric energy is input into it. The weapon turret system is then used to reverse the state of particles in these media, that is, the number of high-energy level particles is higher than the number of low-energy level particles. In this state, when a photon interacts with a particle at a high energy level, it will trigger stimulated radiation. The photons generated by stimulated radiation have the same frequency, phase and propagation direction as the incident photons, thus forming high-energy lasers. Among these, the most important core technology is the core device used to reverse particles in the medium and turret. Without these two core technologies from the fifth-level civilization, the power of laser weapons will be greatly reduced. In the Galactic Alliance, the worst spacecraft are built with ordinary silver-like supermetal materials, and ordinary laser weapons cannot cause any damage to them. Only the specific high-energy laser produced under this special medium can cause devastating damage to spacecraft built with these top-grade materials. Of course, this is also one of the most lethal weapons in the current Galactic Alliance in terms of power. In addition, there are missile turrets and projectile gun turrets. The physical properties of these two are relatively simple, and the former was the main lethal weapon used by human civilization in the Earth era. The same goes for the latter, the basic principle can be the same as for pistol and rifle bullets. The only difference is that it uses some materials with higher explosiveness that are currently unknown to humans to create a higher pressure environment in the barrel, making the bullet leave the barrel faster. There is essentially no difference. Fan Ren read through the lines one by one, and his eyes stayed longest on the laser weapons. According to Maile's explanation and his guess, except for the doomsday weapons of the Titan battleships, most of the conventional weapons of the Sirius civilization currently use the same type of projectile cannons as those used by the Fox civilization. Fan Ren looked at the prices and thought to himself that it was indeed the case.
The average selling price of laser weapon turrets is more expensive than other types of turrets. Moreover, the price of these laser media (ammunition) is not cheap. The price is between tens of thousands of star coins, which is hundreds of times higher than other types of ammunition. This may be due to the fact that the medium of laser weapons can be reused many times. But it cannot change its high price, so that even the Sirius civilization, the overlord of this star field, did not choose this more powerful weapon. The Hans civilization, on the other hand, was simpler and more brutal. The conventional weapons turrets on their warships used simpler and more brutal missile turrets. But as what happened in the previous blocking battle, the power of missile turrets will be greatly reduced when in close combat. Even when facing a blanket attack from a fleet that is several times larger than their own, the missiles cannot effectively penetrate the barrage. There is also a most important reason. Missiles are weapons and equipment that are limited by their tracking systems. If they are deliberately targeted, they are likely to be countered by ECM electronic equipment and become ineffective. As Fan Ren thought, his gaze lingered for a moment, and his mind continued to strengthen the decision that the human fleet should continue to use electromagnetic railguns. However, after looking up the range of similar orbital turrets sold in the Star Domain market, he couldn't help but feel a little anxious. These electromagnetic railguns with higher technological levels, which come from other civilizations, have a range of at least 50% of the electromagnetic railguns of human civilization. The difference is huge! Fan Ren rubbed his sore eyes and slowly closed these options, but his brain did not stop. This time I didn’t come to the Star Domain Market empty-handed. In his hand, he had 720 star coins from the Fox Pirates. Although compared with flagships that cost hundreds of millions or even billions, this amount of money is ridiculously small. But after getting a general understanding of the star domain market, he found that some technical products were completely possible and necessary to acquire. For example, Venus is the planet with the richest metal resources in the solar system. Venus is a planet with extremely valuable resources. It is close in size to the Earth, and due to its special atmospheric environment, a rare and huge amount of tritanium, a building mineral, appears on this terrestrial planet. Through scientific predictions, the mining sector also unanimously believes that silver-like supermetallic mines inside Venus will only appear about 10 kilometers below the ground. This is also a huge mining resource. Once Venus is transformed into an environment suitable for human activities, it is conceivable that humans will be able to set up a super-large mining center here. It is also equipped with ground refining plants and compression plants. It is conceivable that on this planet, which is like a blank sheet of paper and has never been visited by any life, human civilization can completely eliminate all other factors and turn it into a major source of mineral production and processing. This will provide a huge impetus for the development of human civilization. In addition, communication facilities are also an extremely important part. Although thanks to Fan Ren’s efforts, the single effective transmission distance of the quantum communication system used by human civilization has reached 25 billion kilometers.
But this distance is completely unfeasible for use in inter-galactic communications. (End of this chapter)
