When the war in Lao Huang''s world was fierce, Wang Bin and Tiangong technology were also very busy in Wang Bin''s world.


    With the successful development of the first space fighter of Tiangong technology and the start of the first voyage test flight, Wang Bin and his colleagues pay attention to the data information sent back by the space fighter at the command center of Tiangong technology every day. After several days of flight.


    The space fighter finally arrived at the first asteroid that will pass by on the way. The asteroid is not large, only less than 30 meters,


    However, even so, the weight of this asteroid has reached more than 1000 tons. Therefore, it is not easy for ordinary spacecraft to destroy this small meteorite. Even if a large amount of explosives are used, it may not be able to destroy this meteorite.


    It is precisely because of this that this space fighter will take this asteroid as the test flight and the test site for the first airborne weapons.


    As the distance between the space fighter and the meteorite gets closer and closer, Zhao Feng and others are naturally ready, one million kilometers, 900000 kilometers and 500000 kilometers.


    When the distance between the space fighter and the meteorite was only 500000 kilometers, the space fighter launched an attack, and the attack method used this time was an airborne electromagnetic railgun.


    After all, at this time, the distance between the fighter and the meteorite is 500000 kilometers, which is even farther than the distance between the earth and the moon. If ordinary guns are used, it is very difficult to strike accurately at the speed of ordinary machine gun shells.


    However, after all, such a distance is too far, and the speed of ordinary shells is too slow. In the solar system, shells will be affected by the gravity of various planets and the sun, which must be calculated by a large amount of data. Even so, it is very difficult to hit targets 500000 kilometers away


    At the same time, for the purpose of this test, Wang Bin, they also want to see the data calculation and processing ability of this space fighter, and also want to test the detection and positioning ability of this space fighter radar.


    Because when the space fighter set out, Wang Bin and his colleagues only gave the general direction and location of the meteorite of the space fighter, and did not give detailed data.


    When Wang Bin and his Tiangong technology designed this space fighter, according to the design data, the radar detection range of this fighter reached more than one million kilometers. Of course, this is only for targets with a volume of more than five meters.


    Don''t underestimate the volume of five meters. You know, in the universe, the volume of five meters is hardly even an ant, so it is very powerful to detect objects of five meters in millions of kilometers.


    Of course, if the volume of the target is less than 5m, the detection distance will be greatly reduced. If it is only about 1m, the detection distance will be reduced to less than 100000 km.


    However, this time, the volume of the detection target has reached about 30 meters, so according to the data, the detection distance is at least more than one million kilometers.


    This is only a theoretical value. In fact, the effective distance is very different from the theoretical value.


    Take the meteorite with a volume of 30 meters this time. The space fighter was not found until 800000 kilometers, that is, in fact, the radar detection range of this fighter is much smaller than the theoretical value.


    In this regard, Wang Bin and the people of Tiangong technology are not surprised. After all, in the actual use process, due to the influence of various factors, such as cosmic background radiation, solar radiation, the gravity of various planets and so on.


    Therefore, I am very satisfied with this subject matter from Wang Bin and others. After all, it is a detection distance of nearly one million kilometers.


    Don''t think that the detection distance of nearly one million kilometers is already very large. In the cosmic background, in fact, the detection distance of one million kilometers is close at hand, not even in front of him, but it is also very great for human civilization at this time.


    The distance of 55 kilometers, even for very fast railgun shells, is already a very long distance.


    After all, the railgun of the fighter is not a large land-based railgun. It can accelerate the speed of the shell to more than one thousandth of the speed of light. The shell of the fighter''s railgun is only one tenth of that of the Large land-based railgun. Therefore, it takes at least hours to hit a target 500000 kilometers away.


    Then, when the fighter plane was about 400000 kilometers away from the asteroid, the airborne railgun fired ten more railguns.


    However, to the disappointment of Wang Bin and the crew, five or six hours later, the distance between the fighter and the meteorite has been less than 300000 kilometers. However, the meteorite far away from 300000 kilometers has not changed at all, not even the surface dust. It is obvious that two waves of 20 orbital cannons have not hit the meteorite at all.


    Although this has long been expected by Wang Bin and others, according to the calculation data of Wang Bin''s central computer of Tiangong technology, if you want to use orbit to bombard an object with a volume of 30 meters away from 500000 kilometers, the hit rate will never exceed 1 / 1000. If it is about 400000 kilometers, the hit rate will increase to 1%, If it can reach 35 kilometers, the hit rate will reach 10%.


    Of course, this is for the fixed orbit target. If the needle can change the orbit target, its hit rate will be reduced by at least 100 times or even thousands of times.


    It is precisely because of this that Wang Bin will not be surprised.


    Just when the space fighter was 300000 kilometers away from the target, the fighter fired ten more orbital guns and then continued to fly forward.


    Wang Bin and others on the ground, after receiving the information transmitted by the fighter, are quietly waiting for the result of launching these railguns.


    At the same time, they are also very confident in the railgun launched this time. They believe that at least one of the ten shells launched will hit the target. After all, this is a fixed orbit target, not a moving orbit target.


    However, when the space warship approached the meteorite for nearly 200000 kilometers and fired the railgun again, the meteorite had not changed. It was obvious that the railgun fired at 300000 kilometers had not hit the meteorite, or even a shell.


    This result made Wang Bin and Tiangong science and technology look a little ugly. That is to say, the calculation of the target of about 300000 kilometers by the computer inside the fighter is still insufficient, which must be strengthened.


    However, as a space fighter with limited volume, at this time, the space occupied by the computer is very large. If the computing power is added, it will greatly occupy the space of other equipment of the fighter and greatly weaken the combat effectiveness of the fighter, which is very unreasonable.
