This is a tool to protect Chinese Military assets if they have a confrontation with the U.S. over something (like taiwan).
The basic strategy of China in a war would be massive amounts of troops to overwhelm their adversary. While they have created/bought/stolen some very advanced weapon systems, they have not allocated the resourses to mass produce them and train their personel on them. So in a conflict with the U.S. it would be a classic manpower vs. technology conflict.
Problem for them is those are our ABSOULTE FAVORITE types of wars to fight. In a conventional war, which a war with China would be, our overwhelming technical superiority would at the minimum massively damage their military, and could defeat it all together. Remember desert storm? Saddam had the 4th largest military in the world and we crushed it like it was the second string of a pee-wee football team. Bosina? One of the things that shocked our NATO allies was that we could continuously and accurately bomb targets all day and night in ANY weather. They did not have this capability, and this is Europe, not some little third world country. Same with Afghanistan and the begining of the Iraq war.
A big part of that technological superiority comes from our gps satellites and spy satellites. If they could significantly destroy the gps and spy satellites it might significantly degrade our ability to crush their army from far distances. We may be forced to rely on more ground troops and our pilots may have to risk flying lower and closer to their targets to hit them. All of this will result in the increased likelyhood of American casualties. Thus the U.S. would be more likely to negotiate (i.e. give taiwan over to the chicoms) than we would have before.
So, if I'm America, I would be a little worried. If I was taiwan I would be shitting bricks right now
