Currently, satellites are expensive and fragile and can be disrupted by relatively inexpensive weapons. Although several countries possess the latent capability to engage in space warfare, this option has never been exercised. A direct attack against a satellite would be a first and would be unlikely to be an isolated attack. The consequences of engaging in such a conflict would likely be severe. Depending on the scale of the exchange, it is possible that many low-Earth orbit assets could be affected, thereby denying both military and civilian users these resources. This is precisely why the United States must work to dissuade hostile parties from further developing these capabilities, deter them from using them if they do develop them, and be prepared to both respond and minimize the consequences should deterrence fail.
