Adversaries can conduct attacks against our space capabilities using various methods both symmetric and asymmetric. Adversaries may have the capacity to develop counterspace capabilities but, in many cases, may simply acquire them from a third party. Near and far-term threats may include the following:

• Ground system attack and sabotage using conventional and unconventional means against terrestrial nodes and supporting infrastructure.


• Radio frequency (RF) jamming equipment capable of interfering with space system links.


• Laser systems capable of temporarily or permanently degrading or destroying satellite subsystems, thus interfering with satellite mission performance.


• Electromagnetic pulse (EMP) weapons capable of degrading or destroying satellite and/or ground system electronics.


• Kinetic antisatellite (ASAT) weapons capable of destroying spacecraft or degrading their ability to perform their missions.


• IO capabilities capable of corrupting space-based and terrestrial based computer systems utilized to control satellite functions and to collect, process, and disseminate
  mission data.
