After so many years of all-out efforts to promote scientific and technological development, accompanied by many technological breakthroughs over the years, Li Qingsong believes that the time is ripe to develop and manufacture larger Earth-class warships that are more important on the battlefield. Since it is a higher-level battleship, it must have more powerful attack and defense capabilities. It must be able to act like a stabilizing force in the face of any chaotic situation. Once the Earth-class battleship arrives, it can stabilize the situation. It must have unparalleled long-range attack capabilities and be able to cause huge damage to the enemy at a distance of tens of thousands or even hundreds of thousands of kilometers. Only in this way can it cover a sufficiently large battlefield space and transmit its influence to every corner of the battlefield. It also needs to have the longest endurance. In extreme cases, it must be able to fight continuously in the battlefield for several months or even a year without external supplies. It must also have the most stable communication capabilities. It must be able to maintain contact with the strategic version of Goku at all times. At the same time, it can also deliver signals to every Venus-class and Mercury-class battleship on the battlefield, so that these small and medium-sized battleships will not be separated from the whole. Every aspect of it must be the best. Only in this way can it play the role that Li Qingsong hopes it can play. Compared with these places with extremely high requirements, its mobility requirements are not that high. It does not need to have an acceleration of tens or even hundreds of meters per square second like a Mercury-class battleship, nor does it need to be able to go from a standstill to a high speed in an instant. This is also unrealistic for such a huge battleship.
It only needs to have an acceleration between a few tenths of a meter and a few meters per square second. Although the acceleration is low, based on the huge fuel reserves of the Earth-class battleship, it can still maintain a higher cruising speed after accelerating for a period of time. Following this line of thought, Li Qingsong quickly completed the design drawings of the Earth-class battleship. Although the drawings have been designed, Li Qingsong still faces more than ten thousand technical obstacles of varying sizes in order to actually manufacture it. But it doesn’t matter. These obstacles are only technical ones, not related to the principles. We can just tackle them. With Li Qingsong's full commitment, many laboratories reported good news in just half a year. All technical obstacles have been overcome. During this period, various factories designed specifically to meet the needs of Earth-class battleships have been completed. So after completely upgrading the production line and improving the production process, the manufacturing of the first Earth-class battleship began immediately. Just half a year later, a brand new combat spacecraft appeared in Li Qingsong's sight. It is no longer butterfly-shaped like the previous Mercury-class and Venus-class battleships, but looks like two rectangles connected together. The total length of the two cuboids is about 210 meters, of which the larger one is about 150 meters long and has a side length of about 30 meters, while the smaller one has a side length of about 20 meters. One end is big, the other end is small. Its surface is not smooth, but is installed with various equipment, densely packed, almost filling up the total area of more than 30,000 square meters of the entire spacecraft. To go with such a huge size is its equally unprecedented huge mass. In Li Qingsong's plan, the total mass of a Mercury-class battleship fully loaded is about 300 tons, while the mass of a Venus-class battleship rises sharply to about 2,500 tons. At this moment, the Earth-class battleship has once again climbed on the basis of the Venus-class battleship. If fully loaded, the mass directly reaches 16,000 tons! Such a huge mass and such a huge size finally allowed Li Qingsong to let go and install almost all the advanced equipment he developed on it. It is equipped with 3,000 small electromagnetic cannons and laser cannons for defense!
Large electromagnetic cannons and laser cannons used for attack are deployed in various locations, with a total number of more than 100. In addition to these, it also has four super-giant electromagnetic cannons installed one after the other. Because of its extremely long hull, the barrel of the electromagnetic gun can be made very long, and accordingly, the acceleration capability is stronger. Therefore, this super-giant electromagnetic cannon has the ability to accelerate a 10-gram electromagnetic cannon projectile to 20 kilometers per second. The 10-gram electromagnetic cannon projectile is unprecedentedly large. The speed of 20 kilometers per second is also unprecedented for electromagnetic cannons. At this speed, one electromagnetic cannon projectile has an energy of 2 million joules! If converted into TNT explosives, it is equivalent to about half a kilogram of TNT explosives! In the Earth era, the charge of ordinary grenades is usually only a few dozen grams. Therefore, the energy of this projectile is equivalent to the energy of ten high-explosive grenades tied together and exploded. Moreover, when a grenade explodes, the energy is released in all directions. However, once this electromagnetic cannon projectile hits the target, its energy release is extremely concentrated, only in one direction, and the concentration is extremely high, almost no dispersion, and finally all the energy is poured onto the target without any waste, which is much better than ordinary grenades. The electromagnetic cannon projectile is so powerful, and based on the sufficient acceleration ability brought by the long enough hull of the Earth-class battleship, the firing rate of this giant electromagnetic cannon can even reach ten rounds per second! Almost as powerful as a machine gun. In addition to the giant electromagnetic cannon, it is also equipped with four large laser cannons. Also because the mass can be relatively large, the laser beams emitted by these laser cannons have extremely high energy and extremely small divergence angles. In actual verification, these laser beams have a certain lethality even when facing targets 50,000 kilometers away, far exceeding the killing range of Mercury-class battleships and Venus-class battleships, which are at most a few thousand kilometers. In addition to weapons, the high-speed radar it is equipped with also has the most powerful performance. A total of 1,024 deep space scanning modules continuously scan the celestial sphere, collecting information on any target approaching them. Once a target is scanned, up to 3,000 defensive weapons will immediately respond. The supercomputer that serves as the brain of this battleship has performance that is unmatched by other battleships. This supercomputer uses 2048 2-nanometer chips! Including the sensors, controllers, etc. on the spacecraft, the number of chips of various processes and models used in just one Earth-class battleship has exceeded 100,000! At this moment, this huge ship, which was armed from head to toe and had nothing left out, and could truly be called a war beast, began its first voyage since its birth under the control of Li Qingsong.
