According to General Lance Lord of the U.S. Air Force Space Command, the weaponizing of space is afoot. The Air Force has recently deployed an electronic-warfare satellite into Earth’s orbit which is capable of jamming the signals from other satellites.
Disrupting enemy communications isn’t a directly destructive act, but loss of satellite communication has the potential to devastatingly cripple an enemy, so this move will no doubt motivate other countries to deploy their own anti-satellite weapons (with built-in anti-anti-satellite systems). And some of these systems are certain to be destructive rather than just interfering. Not cool.
From the article:
Russia also in the past has deployed anti-satellite weapons and is developing anti-satellite jamming weapons.
Gen. Lord dismissed assertions by critics that the Air Force’s plans to use small spacecraft for maintenance could include using the craft as anti-satellite ramming devices.
Aside: The article also mentions the spiffiest military unit name ever… The 76th Space Control Squadron.
