China's recent project, the asteroid defense system, which can be completed by 2025, is indeed a project that exhilarates and prides the Chinese people.
Some Chinese believe that this system can effectively deal with Musk's StarLink, and some videos and posts about this kind have emerged in an endless stream.
It is certainly possible to use the asteroid defense system against StarLink, but it is not economical and does not have any cost performance. Of course, it is okay to use anti-aircraft guns to hit mosquitoes, it is too wasteful.
It is easy to destroy Musk's star chain, and superpowers can do it, and cost-effective means include microwaves, lasers, missiles, orbital capture devices, and so on. But none of the super-Powers can do so, because they abide by international rules and cannot attack satellites of other countries in peacetime.
Therefore, Musk's star chain mainly takes advantage of loopholes in international rules. Peacetime can not be destroyed, war suddenly and too late to destroy, this star chain is a rule rogue.
The most terrifying thing about Starlink is its suddenness, as long as the United States has a command, thousands of Starlink satellites hanging on its head can instantly become bombs falling from the sky, vertically striking hostile countries, and no country's anti-missile system can defend against such a large number of bombs that fall from the sky and attack vertically.
The main means of the continental asteroid defense system are high-energy missiles, strategic lasers, rocket boosts to change the orbit of the asteroid, small nuclear explosions and other methods. The cost of a single use of these means is very high, and the star chain used to deal with the extremely low cost is of course competent, but no country can afford to burn this money, and the cost-effectiveness ratio is extremely low.
If the continent's asteroid defense system can be used at the military level, its main purpose is to deal with missile raids by rogue countries. For example, some second-rate countries do not have many missiles in their hands, and they cannot form saturation strikes, and can only engage in surprise attacks. At this time, our system can easily shoot down these incoming missiles with a small hand.
In short, there is really no good way to deal with such a rule rogue as the starlink system, or to re-agree on the rules for the use of the orbit of the earth's satellites, or to establish our own star chain, and we can also achieve an instantaneous strike at the enemy country and achieve equivalent deterrence.
